18 Series ZSE/ISE Pressure Switch Precautions Be sure to read before handling. Refer to pages through 2 for safety instructions and pressure switch precautions, and to page for specific product precautions. Warning Design and Selection. Operate the switch only within the specified voltage. Use of the switch outside the range of the specified voltage can cause not only malfunction and damage of the switch but also electrocution and fire. 2. Do not exceed the maximum allowable load specification. A load exceeding the maximum load specification can cause damage to the switch or shorten its operating life span.. Do not use a load that generates surge voltage. Although surge protection is installed in the circuit at the output side of the switch, damage may still occur if a surge is applied repeatedly. When a surge generating load such as a relay or solenoid is directly driven, use a type of switch with a built-in surge absorbing element.. Since the type of applicable fluid varies depending on the product, be sure to verify the specifications. The switches do not have an explosion proof rating. To prevent a possible fire hazard, do not use with flammable gases or fluids. 5. Operate the switch within the regulating pressure range and maximum operating pressure. Malfunction can occur if the pressure sensor is used outside the regulating pressure range, and the sensor may be permanently damaged if used at a pressure that is above the maximum operating pressure. Mounting Warning. If the equipment is not operating properly, do not continue to use it. Connect air and power after installation, repairs, or modifications, and verify proper installation. The switch should be checked for proper operation and possible leaks. 2. Mount switches using the proper tightening torque. When a switch is tightened beyond the specified tightening torque, the mounting screws, mounting bracket, or switch may be damaged. On the other hand, tightening below the specified tightening torque may cause the installation screws to come loose during operation. Warning Warning. Never use in the presence of explosive gases. The switches do not have an explosion proof rating. Never use in the presence of an explosive gas as this may cause a Warning Wiring. Verify the colour and terminal number when wiring. Incorrect wiring can cause the switch to be damaged and malfunction. Verify the colour and the terminal number in the instruction manual when wiring. 2. Avoid repeatedly bending or stretching the lead wire. Repeatedly applying bending stress or stretching force to the lead wire will cause it to break. If you believe the lead wire is damaged and likely to cause malfunctions, replace it.. Confirm proper insulation of wiring. Make sure that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.). Damage may occur due to excess current flow into a switch. Operating Environment Maintenance. Perform periodic inspections to ensure proper operation of the switch. Unexpected malfunctions may cause possible danger. 2. Take precautions when using the switch for an interlock circuit. When a pressure switch is used for an interlock circuit, devise a multiple interlock system to prevent trouble or malfunctioning. Verify the operation of the switch and interlock function on a regular basis. Nominal thread sizes M5 R /8, NPT /8 Tightening torque /6 rotation after tightening by hand 7 to 9 N m. Apply wrench only to the metal part of the main housing when installing the pressure switch onto the system piping. Do not apply a wrench to the resin part as this may damage the switch.

19 Series ZSE/ISE Digital Pressure Switch Precautions Be sure to read before handling. Refer to pages through 2 for safety instructions and pressure switch precautions, and to page for specific product precautions. Warning Selection. Monitor the internal voltage drop of the switch. When operating below a specified voltage, it is possible that the load may be ineffective even though the pressure switch function is normal. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load. Supply voltage Internal voltage drop of switch > Caution. Data of the digital pressure switch will be stored even after the power is turned off. Input data (set pressure, etc.) will be stored in EEPROM so that the data will not be lost after the pressure switch is turned off. (Data will be stored for up to, hours after the power is turned off.) Warning Warning Mounting. Operation Refer to the instruction manual for the operation of the digital pressure switch. 2. Do not touch the LCD indicator. Do not touch the LCD indicator face of the pressure switch during operation. Static electricity can change the readout.. Pressure port Do not introduce any wire or similar object to a pressure port as this may damage the pressure sensor and cause a malfunction. Wiring Minimum operating voltage of load. Do not wire in conjunction with power lines or high voltage lines. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Control circuits including switches may malfunction due to noise from these other lines. 2. Do not allow loads to short circuit. Although digital pressure switches indicate excess current error if loads are short circuited, all incorrect wiring connections cannot be protected. Take precautions to avoid incorrect wiring. As for other pressure switches, the switches will be instantly damaged if loads are short circuited. Take special care to avoid reverse wiring between the brown power supply line and the black output line.. Connect a DC( ) wire (blue) as close as possible to the DC power supply GND terminal. Connecting the power supply away from the GND terminal can cause malfunctions due to noise from devices that are connected to the GND terminal.. Do not attempt to insert or pull the pressure sensor or its connector when the power is on. A switch output malfunction may occur. Air Supply Warning. Use the switch within the specified fluid and ambient temperature range. Ambient and fluid temperature operation is as follows: Digital pressure switches: to 5 C Other pressure switches: to 6 C Take measures to prevent moisture from freezing in circuits when below 5 C, since this may cause damage to the O-ring and lead to a malfunction. The installation of an air dryer is recommended for eliminating condensate and moisture. Never use the switch in an environment where there are drastic temperature changes even when these temperatures are operated within the specified temperature range. 2. Vacuum switch An instant pressure pulse of up to 5kPa (.5MPa) (at the time of vacuum release) will not affect the performance of the switch. However, a constant pressure of 2kPa (.2MPa) or more should be avoided. Warning Operating Environment. Do not use in an area where surges are generated. When there are units that generate a large amount of surge in the area around pressure switches (e.g., solenoid type lifters, high frequency induction furnaces, motors), this may cause deterioration or damage to the switches' internal circuitry. Avoid and protect against sources of surge generation and crossed lines. 2. Operating environment In general, the digital pressure switches featured here are not dust or splashproof. Avoid using in an environment where the likelihood of splashing or spraying of liquids (water, oil, etc.) exists. If used in such an environment, use a dustproof and splashproof type switch. Caution Maintenance. Cleaning of the switch body Wipe off dirt with a soft cloth. If dirt does not come off easily, use a neutral detergent diluted with water to dampen a soft cloth. Wipe the switch only after squeezing the excess water out of the dampened cloth. Then finish off by wiping with a dry cloth afterwards.

20 Series ZSE/ISE Specific Product Precautions Be sure to read before handling. Refer to pages through 2 for safety instructions and pressure switch precautions. Handling Warning. Do not drop, bump, or apply excessive impacts (98m/s2) while handling. Although the body of the sensor may not be damaged, the internal parts of the sensor could be damaged and lead to a malfunction. 2. The tensile strength of the cord is 5N. Applying a greater pulling force on it can cause a malfunction. When handling, hold the body of the sensor do not dangle it from the cord.. Do not exceed the screw-in torque of 7 to 9 N m when installing piping. Exceeding this value may cause malfunctioning of the sensor.. Do not use pressure sensors with corrosive and/or flammable gases or liquids. 5. Allow a sufficient margin of tube length in piping in order to prevent application of torsional, tensile or moment load to the tubes and fittings. 6. When a brand of tubing other than SMC is used, make sure that the tolerance of the tube's O.D. satisfies the following specifications. ) Nylon tubing: ±. mm or less 2) Soft nylon tubing: ±. mm or less ) Polyurethane tubing: +.5 mm or less,.2 mm or less 7. The applicable fluid is air. Please consult SMC if the switch is to be used with other types of fluids. Warning Connection. Incorrect wiring can damage the switch and cause a malfunction or erroneous switch output. Connections should be done while the power is turned off. 2. Do not attempt to insert or pull the pressure sensor or its connector when the power is on. A switch output malfunction may occur.. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Malfunctions may occur due to noise from these other lines.. If a commercial switching regulator is used, make sure that the F.G. terminal is grounded. Warning Operating Environment. Our pressure switches are CE marked; however, they are not equipped with surge protection against lightning. Lightning surge counter measures should be applied directly to system components as necessary. 2. Our pressure switches do not have an explosion proof rating. Never use in the presence of an explosive gas as this may cause a serious explosion.. Do not use in an environment where static electricity can cause problems, otherwise system failure or malfunction may result. Caution 2.

Lever DC polarity indicator Lead wire (brown) Lead wire (black) Lead wire (blue) Do not attempt to insert or pull the pressure sensor or its connector when the power is on. A switch output malfunction may occur. Caution Cut the tube perpendicularly. Hold the tube and insert it into the One-touch fitting carefully and securely all the way to the bottom. One-touch fitting Regulating pressure range and rated pressure range Piping Set the pressure within the rated pressure range. The regulating pressure range is the range of pressure that is possible in setting. The rated pressure range is the range of pressure that satisfies the specifications (accuracy, linearity, etc.) on the sensor. Although it is possible to set a value outside the rated pressure range, the specifications will not be guaranteed even if the value stays within the regulating pressure range.

24 Series ZSE/ISE High speed response: 2.5ms or less With anti-chattering function Stable switch output is possible even with sudden changes in the primary pressure (when operating large bore cylinders, etc.). Pressure Set value P P2 Momentary change Anti-chattering function Devices such as large bore cylinders and high-flow vacuum ejectors consume a large volume of air when they operate, and this may cause a momentary drop in the primary pressure. This function prevents such momentary pressure drops from being detected as abnormal pressures by allowing the response time selection to be changed. [Selectable response times: t] 2.5ms (normal), 2ms, 92ms or 768ms The normal setting is selected when shipped from the factory. (Operating principle) The pressure values measured within the user-selected response time are averaged, and switch output (ON/OFF) is determined by comparing this averaged pressure value with the set pressure. Switch output operation when normal ON OFF Switch output operation when ON anti-chattering OFF function is used t (ms) (Averaging) t (ms) (Averaging) Time Time Time With auto shift function Allows switch output unaffected by variations in primary pressure. Auto shift function Erroneous operation may occur if there is fluctuation in the primary pressure. The auto shift function compensates for pressure changes to ensure proper ON/OFF switch response during such fluctuations. (Operating principle) At the point when the primary pressure fluctuates, the set pressure value is compensated by setting the auto shift input (external input) to low (no-voltage) input, using the pressure measured at that point as a standard. Compound pressure (ZSEF) Able to detect suction pressure (vacuum pressure) and release pressure (positive pressure) with a single pressure switch. Without using auto shift When the primary pressure fluctuates, a correct determination becomes impossible.

36 Series ZSE/ISE5/6 Auto Shift Function This function uses the measured pressure at the time of auto shift input as the reference pressure value and corrects the set point values "P_" and "P_2" of switch output and "P_" and "P_" of switch output 2. "P_" to "P_" correspond to "n_" to "n_" in case of normally closed circuit. When auto shift is not used: Fluctuations in the primary pressure interrupt correct judgment. Pressure Time Auto shift function conditions and explanation Keep the pressure constant at least for 5 ms after the last transition signal of auto shift input. At the time of auto shift input, the display unit displays "ooo" for about second. The pressure value at this time is saved as the correction value "C_5". The set point values "P_" to "P_" or "n_" to "n_" are corrected based on the saved correction values. The time between the auto shift input and start of switch output is ms or less. If the set point value corrected by auto shift input falls out of the possible set range, the correction value is not saved. The display will show "UUU" if the set point value is above the upper limit and "LLL" if it is below the lower limit. The correction value "C_5" set by auto shift input disappears when the power is turned off. The correction value "C_5" for the auto shift function is reset to zero (the initial value) when the power is turned on again. When auto shift is used: When the primary pressure changes, set the auto shift function to Lo. The pressure value at this point will be saved as the reference value to correct the pressure set point values in order to make The correction value is not stored on the EEPROM. The possible set range for types with auto shift function is as follows: correct judgments.

49 5 5 Series High ZSE Precision 6F/ISE Digital Pressure 6 Switch Series ZSE/ISE5/6 Pressure Switch Precautions Be sure to read before handling. Refer to pages 7 through 9 for safety instructions and pressure switch precautions, and to page 2 for specific product precautions. Warning Design and Selection. Operate the switch only within the specified voltage. Use of the switch outside the range of the specified voltage can cause not only malfunction and damage to the switch but also electric shocks and fire. 2. Do not exceed the maximum allowable load specification. A load exceeding the maximum load specification can cause damage to the switch or shorten its operating life.. Do not use a load that generates surge voltage. Although surge protection is installed in the circuit at the output side of the switch, damage may still occur if a surge is applied repeatedly. When a surge generating load such as a relay or solenoid is directly driven, use a type of switch with a built-in surge absorbing element.. The fluid compatibility varies among products. Be sure to confirm the specifications. The switch does not have an explosion proof rating. To prevent a possible fire hazard, do not use with flammable gases or fluids. 5. Operate the switch within the regulating pressure range and maximum operating pressure. Malfunction can occur if the pressure sensor is used outside the regulating pressure range, and the sensor may be permanently damaged if used at a pressure that is above the maximum operating pressure. Warning Mounting. If the equipment is not operating properly, do not continue to use it. Connect air and power after installation, repairs, or modifications, and verify proper installation. The switch should be checked for proper operation and possible leaks. 2. Mount switches using the proper tightening torque. When a switch is tightened beyond the specified tightening torque, the mounting screws, mounting bracket, or switch may be damaged. On the other hand, tightening below the specified tightening torque may cause the installation screws to come loose during operation. Nominal thread size M5 R /, NPT /, G /, URJ /, TSJ / Proper tightening torque N. m /6 rotation after tightening by hand.6n. m. Apply wrench only to the metal part of the main housing when installing the pressure switch onto the system piping. Do not apply a wrench to the resin part as this may damage the switch. Warning Wiring. Confirm the colours and terminal numbers of cords when wiring. Incorrect wiring can cause the switch to be damaged and malfunction. Verify the colours and terminal number in the instruction manual when wiring. 2. Avoid repeatedly bending or stretching lead wires. Repeatedly applying bending stress or stretching force to the lead wire will cause it to break. If you believe the lead wire is damaged and likely to cause malfunctions, replace it.. Confirm proper insulation of wiring. Make sure that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.). Damage may occur due to excess current flow into a switch. Warning Warning Operating Environment. Never use in the presence of explosive gases. The switches do not have an explosion proof rating. Never use in the presence of an explosive gas as this may cause a serious explosion. Maintenance. Perform periodic inspections to ensure proper operation of the switch. Unexpected malfunctions or incorrect operation may cause possible danger. 2. Take precautions when using the switch for an interlock circuit. When a pressure switch is used for an interlock circuit, devise a multiple interlock system to prevent trouble or malfunctioning. Verify the operation of the switch and interlock function on a regular basis. PSE5 PSE5 ISE7/75/75H ZSE/ISE5/6 ZSE/ISE ZSE/ISE PSE55 PSE56 PSE2 PF2D PF2W PF2A ISA2 PSE 5

50 5 Series ZSE/ISE5/6 Series 6F/ISE 5 6 Digital Pressure Switch Precautions Be sure to read before handling. Refer to pages 7 through 9 for safety instructions and pressure switch precautions, and to page 2 for specific product precautions. Warning Warning Selection. Monitor the internal voltage drop of the switch. When operating below a specified voltage, it is possible that the load may be ineffective even though the pressure switch function is normal. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load. Supply voltage Caution Mounting. Operation Refer to the instruction manual for the operation of the digital pressure switch. 2. Pressure port Do not introduce any wire or similar object to a pressure port as this may damage the pressure sensor and cause a malfunction. Warning Internal voltage > drop of switch. Data of the digital pressure switch will be stored even after the power is turned off. Input data (set pressure, etc.) will be stored in EEPROM so that the data will not be lost after the pressure switch is turned off. (Data will be stored for up to, hours after the power is turned off.) Wiring Minimum operating voltage of load. Do not wire conjunction with power lines or high voltage lines. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Control circuit including the switches may malfunction due to noise from these other lines. 2. Do not allow loads to short circuit. Although digital pressure switches indicate excess current error if loads are short circuited, all incorrect wiring connections cannot be protected. Take precautions to avoid incorrect wiring. As for other pressure switches, the switches will be instantly damaged if loads are short circuited. Take special care to avoid reverse wiring between the brown power supply line and the black output line.. Connect a DC (-) wire (blue) as close as possible to the DC power supply GND terminal. Connecting the power supply away from the GND terminal can cause malfunctions due to noise from devices that are connected to the GND terminal.. Do not attempt to insert or pull the pressure sensor or its connector when the power is on. Pressure Source Warning. Use the switch within the specified fluid and ambient temperature range. Ambient and fluid temperature operation is as follows: Digital pressure switches: to 5 C Take measures to prevent moisture from freezing in circuits when below 5 C, since this may cause damage to the O-ring and lead to a malfunction. The installation of an air dryer is recommended for eliminating condensate and moisture. Never use the switch in an environment where there are drastic temperature changes even when these temperatures are operated within the specified temperature range. 2. Compound pressure switch Although application of a momentary pressure around.5 MPa will not affect the performance (at the time of vacuum break), be careful to not to apply constant pressure of.2 MPa or more. Warning Operating Environment. Do not use in an area where surges are generated. When there are units that generate a large amount of surge in the area around pressure switches (e.g., solenoid type lifters, high frequency induction furnaces, motors), this may cause deterioration or damage to the switches' internal circuitry. Avoid and protect against sources of surge generation and crossed lines. Caution Maintenance. Cleaning of the switch body. Wipe off dirt with soft cloth. If dirt does not come off easily, use a neutral detergent diluted with water to dampen a soft cloth. Wipe the switch only after squeezing the excess water out of the dampened cloth. Then finish off by wiping with a dry cloth afterwards. 6

51 5 5 Series High ZSE Precision 6F/ISE Digital Pressure 6 Switch Series ZSE/ISE5/6 Pressure Switch Precautions Be sure to read before handling. Refer to pages 7 through 9 for safety instructions and pressure switch common precautions. Warning. Do not drop, or apply excessive impact (98m/s 2 ) while handing. Although the body of the sensor may not be damaged, the internal parts of the sensor could be damaged and lead to a malfunction. 2. The tensile strength of the cord is 9N. Applying a greater pulling force on it can cause a malfunction. When handling, hold the body of the sensor do not dangle it from the cord.. Do not exceed the screw-in torque of.6 N m when installing piping. Exceeding this value may cause malfunctioning of the sensor.. Do not use pressure sensors with corrosive and/or flammable gases or liquids. Warning Caution Handling Connection. Incorrect wiring can damage the switch and cause a malfunction or erroneous switch output. 2. Turn off the power before connecting the wires.. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Malfunctions may occur due to noise from these lines.. If a commercial switching regulator is used, make sure that the F.G. terminal is grounded. Operating Environment Warning. Our pressure switches are CE marked; however, they are not equipped with surge protection against lightning. Lightning surge countermeasures should be applied directly to system components as necessary. 2. Our pressure switches do not have an explosion proof rating. Never use it in the presence of an explosive gas as this may cause a serious explosion.. Do not use in an environment with spattering liquid of oil or solvent. 2. In an environment where the body of the switch is exposed to water or dust, there is possibility of water or dust invasion of the switch through the atmospheric release port. Insert a ø tube (with inside diameter of ø2.5) into the atmospheric release port and pipe the other end to a place with no spattering water or other liquid. Do not fold or clog the tube or the pressure cannot be measured properly. To a safe place with no water or dust Air tube Atmospheric release port Confirm that the air tube is inserted to the bottom of the atmospheric release port. Use SMC TU25 (Material: Polyurethane, O.D.: ø, I.D: ø2.5) as the air tube. Warning Pressure Source. Use of toxic, corrosive or flammable gas. The materials of the pressure sensor and fittings on the switch are SUS6 and SUS. Do not use toxic or corrosive gas. The switch is not protected against explosion. Do not use it with flammable gas, either. 2. Compatible fluid The fluid contact areas are SUS6 (pressure sensor) or SUS (fittings). Use fluid that will not corrode the materials. (For corrosiveness of fluid, consult the manufacturer of the fluid.) <ZSE6F/ISE6> Helium leakage test Helium leakage test is conducted on the welding parts. Use a ferrule a ferrule by (Swagelok fittings) as the TSJ fittings and packing, ground, etc. by Cajon (VCR fittings) as the URJ fittings. If a ferrule, packing or ground by other manufacturers are to be used, conduct helium leakage test before using those products. Mounting Method Caution. Mounting with panel mount adapter Panel mounting adapter A 2. Mounting with brackets Mount a bracket to the using two M x 5L mounting screws and install on piping with a hexagon socket cap screws. The switch can be installed horizontally depending on the installation location. Mounting screw M x 5L Bracket A or D Front protection cover (optional) Panel mounting adapter B Panel The tightening torque for bracket mounting screw should be.98n m or less.

61 Series Digital ISE7/75/75H Pressure Switch for General Fluids Series ISE7/75/75H Pressure Switch Precautions Be sure to read before handling. Warning Design and Selection. Operate the switch only within the specified voltage. Use of the switch outside the range of the specified voltage can cause not only malfunction and damage of the switch but also electrocution and fire. 2. Do not exceed the maximum allowable load specification. A load exceeding the maximum load specification can cause damage to the switch or shorten its operating life span.. Do not use a load that generates surge voltage. Although surge protection is installed in the circuit at the output side of the switch, damage may still occur if a surge is applied repeatedly. When a surge generating load such as a relay or solenoid is directly driven, use a type of switch with a built-in surge absorbing element.. Since the type of applicable fluid varies depending on the product, be sure to verify the specifications. The switches do not have an explosion proof rating. To prevent a possible fire hazard, do not use with flammable gases or fluids. 5. Strictly adhere to the rated pressure range and the maximum withstand pressure. Operating the switch under pressures exceeding the range may cause the switch to malfunction. If surge pressures exceeding the maximum withstand pressure are likely to arise, take measures to prevent such surge pressures from being applied to the switch. Operating the switch under pressures exceeding the maximum operating pressure may destroy the switch. Mounting Warning. If the equipment is not operating properly, do not continue to use it. Connect air and power after installation, repairs, or modifications, and verify proper installation. The switch should be checked for proper operation and possible leaks. 2. Apply wrench only to the metal part of the main housing when installing the pressure switch onto the system piping. Do not apply a wrench to the body part as this may damage the switch. Warning Warning Wiring. Verify the colour and terminal number when wiring. Incorrect wiring can cause the switch to be damaged and malfunction. Verify the color and the terminal number in the instruction manual when wiring. 2. Avoid repeatedly bending or stretching the lead wire. Repeatedly applying bending stress or stretching force to the lead wire will cause it to break. If you believe the lead wire is damaged and likely to cause malfunctions, replace it.. Confirm proper insulation of wiring. Make sure that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.). Damage may occur due to excess current flow into a switch. Operating Environment Warning. Never use in the presence of explosive gases. The switches do not have an explosion proof rating. Never use in the presence of an explosive gas as this may cause a serious explosion. Maintenance. Perform periodic inspections to ensure proper operation of the switch. Unexpected malfunctions may cause possible danger. 2. Take precautions when using the switch for an interlock circuit. When a pressure switch is used for an interlock circuit, devise a multiple interlock system to prevent trouble or malfunctioning. Verify the operation of the switch and interlock function on a regular basis. PSE5 PSE5 ISE7/75/75H ZSE/ISE5/6 ZSE/ISE ZSE/ISE PSE55 PSE56 PSE2 PF2D PF2W PF2A ISA2 PSE 57

62 Series ISE7/75/75H Series ISE7/75/75H Digital Pressure Switch Precautions Be sure to read before handling. 58 Warning Warning Warning Selection. Monitor the internal voltage drop of the switch. When operating below a specified voltage, it is possible that the load may be ineffective even though the pressure switch function is normal. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load. Supply voltage Internal voltage drop of switch > Caution. Data of the digital pressure switch will be stored even after the power is turned off. Input data (set pressure, etc.) will be stored in EEPROM so that the data will not be lost after the pressure switch is turned off. (Data will be stored for up to, hours after the power is turned off.) Mounting Wiring Minimum operating voltage of load. Operation Refer to the instruction manual for the operation of the digital pressure switch. 2. Pressure port Do not introduce any wire or similar object to a pressure port as this may damage the pressure sensor and cause a malfunction.. Do not wire in conjunction with power lines or high voltage lines. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Control circuits including switches may malfunction due to noise from these other lines. 2. Do not allow loads to short circuit. Although digital pressure switches indicate excess current error if loads are short circuited, all incorrect wiring connections cannot be protected. Take precautions to avoid incorrect wiring.. Connect a DC( ) wire (blue) as close as possible to the DC power supply GND terminal. Connecting the power supply away from the GND terminal can cause malfunctions due to noise from devices that are connected to the GND terminal.. Do not attempt to insert or pull the pressure sensor or its connector when the power is on. 5. A cable with a right-angled connector is also available. The right-angled connector faces down (toward the piping). Do not attempt to rotate the connector, as it is not rotatable. Pressure Sources Warning. Use the switch within the specified fluid and ambient temperature range. Take measures to prevent moisture from freezing in circuits when below 5 C, since this may cause lead to a malfunction. The installation of an air dryer is recommended for eliminating condensate and moisture. Never use the switch in an environment where there are drastic temperature changes even when these temperatures are operated within the specified temperature range. Warning Operating Environment. Do not use in an area where surges are generated. When there are units that generate a large amount of surge in the area around pressure switches (e.g., solenoid type lifters, high frequency induction furnaces, motors), this may cause deterioration or damage to the switches' internal circuitry. Avoid and protect against sources of surge generation and crossed lines. Caution Maintenance. Cleaning of the switch body Wipe off dirt with a soft cloth. If dirt does not come off easily, use a neutral detergent diluted with water to dampen a soft cloth. Wipe the switch only after squeezing the excess water out of the dampened cloth. Then finish off by wiping with a dry cloth afterwards.

63 Series Digital ISE7/75/75H Pressure Switch for General Fluids Series ISE7/75/75H Specific Product Precautions Be sure to read before handling. Refer to pages 7 through 9 for safety instructions and pressure switch precautions. Warning. Do not drop, bump, or apply excessive impacts (98m/s2) while handling. Although the body of the sensor may not be damaged, the internal parts of the sensor could be damaged and lead to a malfunction. 2. The tensile strength of the cord is 5N. Applying a greater pulling force on it can cause a malfunction. When handling, hold the body of the sensor do not dangle it from the cord.. Do not exceed the screw-in torque of N m for ISE7 and 8 N m for ISE75/75H when connecting the pipe to the switch. Exceeding these values may cause the switch to malfunction.. Do not use pressure sensors with corrosive and/poisonous or flammable gases or liquids. 5. When connecting the pipe to the switch, engage the wrench horizontally to the chamfered barrel of the fitting. Be careful not to apply excessive force to the switch's main unit. Warning Handling Connection. Incorrect wiring can damage the switch and cause a malfunction or erroneous switch output. 2. Connections should be done while the power is turned off.. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Malfunctions may occur due to noise from these other lines.. If a commercial switching regulator is used, make sure that the F.G. terminal is grounded. Warning. Our pressure switches are CE marked; however, they are not equipped with surge protection against lightning. Lightning surge countermeasures should be applied directly to system components as necessary. 2. Our pressure switches do not have an explosion proof rating. Never use in the presence of an explosive gas as this may cause a serious explosion. Caution. Do not use in an environment with spattering liquid of oil or solvent. Warning Operating Environment. Regarding poisonous, corrosive or combustible gases Do not use the switch for poisonous or corrosive gases. Also note that the switch is not explosion-proof. 2. Regarding use of the switch for fluids Do not use the switch for any corrosive or flammable gas or fluid (ISE7 series). Do not use the switch for any fluid capable of corroding SUS or SUS6 stainless steel; or for any flammable gas or liquid (ISE75/75H series). (For information on the corrosiveness of fluids, contact the fluid manufacturers.) Caution Bracket B Pressure Sources Mounting. Connecting pipe to the switch When connecting the pipe to the switch, apply a torque of.6 N m or greater for the ISE7 series and a torque of 25 N m or greater for the ISE75/75H series. 2. Bracket-mounting the switch Interlock the neck of the switch's piping port between the bracket assembly and bracket B. Using two M6 screws, mount the switch onto a wall. If the panel thickness is less than 5 mm, use nuts or other alternative means to increase the mounting strength. OUT U P SET DOWN Bracket B and the bracket assembly make up one set.

100 Series PSE2/ Function Details A Auto shift function When there are large fluctuations in the supply pressure, the switch may fail to operate correctly. The auto shift function compensates such supply pressure fluctuations. It measures the (differential) pressure at the time of auto shift signal input and uses it as the reference (differential) pressure to correct the set value on the switch. Set value correction by auto shift function Supply pressure Supply pressure normal drop (Differential) Pressure Switch output (2) Auto shift input Rectified value When the auto shift is selected, ooo will be displayed for approximately second, and the pressure value at that point will be saved as a rectified value C_5 (for CH of PSE2 and PSE) or C_ (for CH2 to for PSE2). Based on the saved rectified values (Note), the set value P_ to P_ (for PSE2) or P_, H_, P_, H_2 (for PSE) will likewise be rectified. Note) When an output is reversed, n_ to n_ (for PSE2) or n_, H_, n_, H_2 (for PSE) will be rectified.

B Auto preset function Auto preset function, when selected in the initial setting, calculates and stores the set value from the measured (differential) pressure. The optimum set value is determined automatically by repeating vacuum and break with the target workpiece several times.

101 Digital Pressure Sensor Controller Series PSE2/ Function Details G Error indication function Error name Overcurrent error Residual pressure error Applied pressure error Auto shift error System error Error code PSE2 PSE Description H Copy function (Series PSE2 only) Information that can be copied includes the following: q Pressure set values, w Range settings, e Display units, r Output modes, t Response times. When CH is copied to CH2, CH, and CH, information of OUT in CH will be copied. When CH2, CH, or CH is copied to CH, information of OUT in CH2, CH, or CH will be copied only to OUT in CH. Note) When the copy function is used, the regulating pressure value of the copied channel may change ± digit. I current of switch output (OUT) exceeds 8 ma. current of switch output (OUT2) exceeds 8 ma. Pressure applied during the zero reset operation exceeds ±7% F.S. After displaying the error code for seconds, the switch automatically returns to the measuring mode. Due to individual product differences, the setting range varies ± digits. Supply pressure exceeds the maximum set (differential) pressure or upper limit of the display pressure. A sensor may be disconnected or miswired. Or, supply pressure is below the minimum set (differential) pressure or lower limit of the display pressure. The value measured at the time of auto shift input is outside the set (differential) pressure range. After displaying the error code for one second, the switch returns to the measuring mode. Internal data error Internal data error Internal data error Internal data error Auto identification function (Series PSE2 only) This function automatically identifies the pressure range of the pressure sensor that is connected to the multi-channel pressure sensor controller, thus eliminating the need of having to reset the range again after replacing the sensor. This function will be activated either when Aon is set in the auto identification mode or when the power is turned back on in that condition. However, this function only works in conjunction with specific pressure sensors (SMC Series PSE5). When other pressure sensors are used, this function will not work. When using other types of pressure sensors, first set the auto identification mode to AoF, and then proceed to setting the range. Turning the power back on while in the Aon setting can cause a malfunction. J Anti-chattering function A large bore cylinder or ejector consumes a large volume of air in operation and may experience a temporary drop in the supply pressure. This function prevents detection of such temporary drops in the supply pressure as an error. <Principle> This function averages pressure values measured during the response time set by the user and then compares the average pressure value with the pressure set point value to output the result on the switch.

104 Pressure Switch Precautions Be sure to read before handling. Refer to back page for Safety Instructions, and back page 5 through to 8 for Specific Product Precautions. Warning Design and Selection. Operate a switch only within the specified voltage. Use of a switch outside the range of the specified voltage can cause not only malfunction and damage of a switch, but also electrocution and fire. 2. Do not exceed the maximum allowable load specification. A load exceeding the maximum load specification can cause damage to the switch or shorten its operating life span.. Do not use a load that generates surge voltage. Although surge protection is installed in the circuit at the output side of the switch, damage may still occur if a surge is applied repeatedly. When a surge generating load such as a relay or solenoid is directly driven, use a type of switch with a built-in surge absorbing element.. Since the type of applicable fluid varies depending on the product, make sure to verify the specifications. Switch is not of an explosion proof construction. To prevent a possible fire hazard, do not use with flammable gases or fluids. 5. Operate a switch within the regulating pressure range and maximum operating pressure. Using beyond the specified range may result in a malfunction. If surge pressure exceeding the maximum withstand pressure are likely to arise, take measure to prevent such surge pressures from being applied to the switch. Use of a switch beyond the maximum operating pressure may result in a breakdown. Warning Mounting. If the equipment is not operating properly, do not continue to use it. Connect air and power after installation, repairs, or modifications, and verify if installed properly or not by conducting a performance and leak test properly. 2. Mount a switch by observing the proper tightening torque. When a switch is tightened beyond the specified tightening torque, the mounting screws, mounting bracket, or switch may be damaged. On the other hand, tightening below the specified tightening torque may cause the installation screws to come loose during operation. Connection thread: M, M5, Rc, R, NPT Warning Wiring. Verify the colour and terminal number when wiring. Incorrect wiring can cause the switch to be damaged and malfunction. Verify the colour and the terminal number in the instruction manual when wiring. 2. Avoid repeatedly bending or stretching the lead wire. Repeatedly applying bending stress or stretching force to the lead wire will cause it to break. If you believe the lead wire is damaged and likely to cause malfunctions, replace the product. (Grommet and lead wire is irreplaceable one.). Confirm proper insulation of wiring. Make sure that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.). Damage may occur due to excess current flow into a switch. Warning Warning Operating Environment. Never use in the presence of explosive gases. The switches do not have an explosion proof rating. Never use in the presence of an explosive gas as this may cause a serious explosion. Maintenance. Perform periodic inspections to ensure proper operation of the switch. Unexpected malfunctions may cause possible danger. 2. Take precautions when using a switch for an interlock circuitry. When a pressure switch is used for an interlock circuit, devise a multiple interlock system to prevent trouble or malfunction. Verify the operation of the switch and interlock function on a regular basis. Thread M, M5 /8 / Proper tightening torque (N m) /6 rotation after tightening by hand 7 to 9 2 to. Apply a wrench only to the metal part of the main housing when installing a pressure switch in the system piping. Never apply a wrench to the resin part, since it may result in damage to a switch.

105 Digital Pressure Switch Precautions Be sure to read before handling. Refer to back page for Safety Instructions, and back page 5 through to 8 for Specific Product Precautions. Warning Selection. Monitor the internal voltage drop of a switch. When operating below the specified voltage, it is possible that a load may be ineffective, even though the pressure switch functions normally. Therefore, the formula below should be satisfied after confirming the voltage of operating load. Supply voltage Caution Warning Internal voltage drop of switch. Pressure switch for placement verification Use the Air Catch Sensor/Series ISA for the purpose of placement verification of a work. The ISA series is both dustproof and drip proof. 2. Data of the digital pressure switch will be stored even after the power is turned off. Input data (set pressure, etc.) is stored in EEPROM, so that the data will not be lost after the pressure switch is turned off. (Data is stored for up to, hours after the power is turned off.) Mounting. Do not drop or apply the excessive force to a switch when handling. Do not drop, bump, or apply excessive impact ( m/s 2 or greater) while handling. Although the body of the switch case may not be damaged, the inside of the switch could be damaged and lead to a malfunction. 2. Hold the body of the switch while handling. If the product is held by its cable, it could lead to a breakage. Hold the body of the switch while handling.. Operation Refer to the instruction manual for operating by the button for the digital pressure switch.. Do not touch the LCD readout. Do not touch the LCD indicator face of the pressure switch during operation. Static electricity can change the readout. 5. Pressure port Do not introduce any wire or similar object to a pressure port as this may damage the pressure sensor and cause a malfunction. > Voltage of operation load Warning Wiring. Do not wire in conjunction with power lines or high voltage lines. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Control circuits including switches may malfunction due to noise from these other lines. 2. Do not allow loads to short circuit. (-wire type) Although digital pressure switches indicate excess current error if loads are short circuited, all incorrect wiring connections cannot be protected. Take precautions to avoid incorrect wiring. As for other pressure switches, the switches will be instantly damaged if loads are short circuited. Take special care to avoid reverse wiring between the brown power supply line and the black output line. PSE5 PSE5 ISE7/75/75H ZSE/ISE5/6 ZSE/ISE ZSE/ISE PSE55 PSE56 PSE2 PF2D PF2W PF2A ISA2 PSE

106 Digital Pressure Switch Precautions 2 Be sure to read before handling. Refer to back page for Safety Instructions, and back page 5 through to 8 for Specific Product Precautions. Caution Piping. Piping hose, etc. When panel mounting the product, if excessive force is applied to the switch by piping material such as hose, it could lead to the connecting parts of the switch becoming damaged. Therefore, be careful not to apply such excessive force. Caution Maintenance. Cleaning of the switch body Wipe off dirt with a soft cloth. If dirt does not come off easily, use a neutral detergent diluted with water to dampen a soft cloth. Wipe the switch only after squeezing the excess water out of the dampened cloth. Then finish off by wiping with a dry cloth afterwards. Warning Air Supply. Use the switch within the specified fluid and ambient temperature range. Ambient and fluid temperature operation for the PSE56 series should be within to 6 C. Meanwhile, other remote type pressure switches should be within to 5 C. Take measures to prevent moisture from freezing in circuits when below 5 C, since this may cause damage to the O-ring and lead to a malfunction. The installation of an air dryer is recommended for eliminating condensate and moisture. Never use the switch in an environment where there are drastic temperature changes even when these temperatures are operated within the specified temperature range. 2. Vacuum switch An instant pressure pulse of up to.5 MPa (at the time of vacuum release) will not affect the performance of the switch. However, a constant pressure.2 MPa or more should be avoided. Warning Operating Environment. Do not use in an area where surges are generated. When there are units that generate a large amount of surge in the area around pressure switches (e.g., solenoid type lifters, high frequency induction furnaces, motors), this may cause deterioration or damage to the switches internal circuitry. Avoid and protect against sources of surge generation and crossed lines. 2. Operating environment In general, the digital pressure switches featured here are not dust or splashproof. Avoid using in an environment where the likelihood of splashing or spraying of liquids (water, oil, etc.) exists. If used in such an environment, use a dustproof and splashproof type switch. 2

130 Series ISA2 Series ISA2 Common Precautions Be sure to read before handling. Warning Design and Selection. Operate the switch only within the specified voltage. Use of the switch outside the range of the specified voltage can cause not only malfunction and damage to the switch but also electric shocks and fire. 2. Never apply a load above the maximum load capacity. It can damage the air catch sensor or shorten the life time.. Do not use a load that generates surge voltage. Although the output circuit of the air catch sensor is equipped for surge protection, repeated application of surges can damage the air catch sensor. When a load, such as a relay or solenoid, which generates surge is directly driven, use a type of switch having a built-in surge absorbing element.. Be sure to observe the set pressure range and maximum operating pressure. Use of the air catch sensor outside the range of the specified pressure can cause failure. Use at a pressure exceeding the maximum operating pressure may damage the air catch sensor. 5. Be aware of internal voltage drops of the air catch sensor. When the air catch sensor is used below the specified voltage, even if the air catch sensor operates normally, the load may fail to operate. Confirm the operating voltage of the load and adjust it to satisfy the formula below. Power supply - Internal voltage drop > voltage of air catch sensor operating voltage 6. Quality of operating air. Use clean air. Do not use compressed air which includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction. 2. Install air filters. Install air filters at the upstream side of valves, The filtration degree should be 5µm or finer.. Install an after cooler, air dryer or water separator, etc. Air that includes excessive drainage may cause malfunction of valves and other pneumatic equipment. To prevent this, install an after cooler, air dryer or water separator, etc. Warning Mounting. Do not use the switch unless it operates normally. After installation, repair or reform, connect air and electricity and conduct appropriate function and leakage tests to confirm proper installation. 2. Observe the prescribed tightening torque in installation. If screws are tightened with a force beyond the tightening torque range, it can cause damage to the mounting screws, mounting brackets and switches. If the force is below the tightening torque range, the fixing screws can come loose during operation. connection thread :/8, / Nominal size M5 /8 /.

131 Series ISA2 Modular Air Catch Sensor for Work Detection Series ISA2 Common Precautions 2 Be sure to read before handling. Warning Warning Wiring. Confirm the colours and terminal numbers of the wires when connecting. Incorrect wiring can lead to damage, failure and malfunction. Confirm colours and terminal numbers in the operation manual when wiring. 2. Avoid repeatedly bending or stretching lead wires. Broken wires will result from applying repeated bending stress or stretching force to the lead wires. Replace any lead wire that is damaged and can possibly cause malfunction.. Confirm proper insulation of wiring. Be certain that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.) Damage may occur due to excess current flow into an air catch sensor.. Do not run wiring near power lines or high voltage lines. Wire separately from power lines or high voltage lines, avoiding parallel wiring or wiring in the same conduit with these lines. Control circuits containing auto switches may malfunction due to noise from these other lines. 5. Do not allow short circuit of loads. Take special care to avoid reverse wiring with the power supply line (brown) and the output line (black). Operating Environment. Never use in an atmosphere of explosive gases. The construction of air catch sensor is not intended to prevent explosion. Never use in an atmosphere with an explosive gas since this may cause a serious explosion. 2. Do not use in an atmosphere of corrosive gases, chemicals, sea water, water, or vapor or in an environment where such a substance adheres.. Do not use in environment where vibration or impact occurs.. Do not operate in a location near a heat source or where radiated heat will be received. 5. Take proper protection measures in an environment where water splashes, oil or spatters from welding may adhere to the product. 6. Do not use in locations where surge is generated. If there is equipment generating a large surge (such as a solenoid lifter, high frequency induction furnace or motor) around the air catch sensor, it can deteriorate or damage the circuit elements inside the air catch sensor. Apply surge protection measures to the source of the surge and keep the lines apart from each other. Pressure Source Warning. Use the air catch sensor within the specified fluid and ambient temperature range. The fluid and ambient temperature are to 6 C. Take measures to prevent freezing, since moisture in circuits may be frozen at or below 5 C, which can cause damage the O-ring and lead to malfunction. Installation of an air dryer is recommended to remove drain and moisture. Do not use the air catch sensor in an environment with sudden temperature changes even if the ambient temperature range is compliant with the specifications. Caution Piping. Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. Do not allow tensile, contracting or bending forces by piping to be applied to the valve body. 2. Wrapping of pipe tape When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealing material do not get inside the piping. Also, when pipe tape is used, leave.5 to 2 thread ridges exposed at the end of the threads. Wrapping direction Expose approx. 2 threads Pipe tape PSE5 PSE5 ISE7/75/75H ZSE/ISE5/6 ZSE/ISE ZSE/ISE PSE55 PSE56 PSE2 PF2D PF2W PF2A ISA2 PSE 27

132 Series ISA2 Series ISA2 Specific Product Precautions Be sure to read before handling. Air Catch Sensor Series ISA2 Warning Operating Environment. Do not use in an environment where vibration or impact occurs. Use a bracket in an environment with vibration exceeding m/s The enclosure of the switch conforms to IP66 and that for the solenoid valve to IP65. The pressure gauge and the regulator have open constructions. Take proper protection measures in an environment where water splashes, oil or spatters from welding may adhere to the product.. Since steel piping lacking flexibility is easily affected by moment loads or propagation of vibration, employ flexible tubing, etc., to prevent interactions of such factors.. Although CE accredited, this air catch sensor is not equipped with surge protection against lightning. Necessary counter-measures for possible lightning surge should be fitted to system components as required. 5. Do not operate in locations having an atmosphere of flammable, explosive or corrosive gases, which can result in fire, explosion or corrosion. The air catch sensor does not have an explosion proof rating. Caution. When an air catch sensor is contained in a box, provide an air outlet to constantly keep the atmospheric pressure inside the box. Internal pressure rises will hinder normal air discharge and may lead to possible malfunction. 2. The air outlet is provided on the setting dial section of the air catch sensor. Do not turn off air supply to the switch if water or cutting oil splashes around the setting dial. Caution Mounting. If the detection nozzle is exposed to splashes of water or cutting oil, do not allow backflow from the detection nozzle to the switch body. Install the switch body at a position higher than the detection nozzle wherever possible. Caution Piping. Piping equipment In the piping between the switch body and the detection nozzle, do not use equipment or fittings that can possibly cause leakage or serve as resistance. Do not use one-touch fittings in an environment where the air catch sensor is exposed to water or other liquid. 2 Port Solenoid Valve Series VCA Warning Precautions on Design. Energised continuously Consult SMC if the product is to be energised continuously for long periods of time. Caution Selection.

177 Series PF2A/PF2W Specific Product Precautions Be sure to read before handling. Refer to page 7 for safety instructions. Digital Flow Sensors & Switches for Air/Water Series PF2A/PF2W Warning Design and Selection. Operate the switch only within the specified voltage. Use of the switch outside of the specified voltage range can cause not only a malfunction and damage to the switch, but it can also cause electrical shock and fire. 2. Do not exceed the maximum allowable load specification. A load exceeding the maximum load specification can cause damage to the switch.. Do not use a load that generates a surge voltage. Although the circuit at the output side of the switch is surgeprotected, damage may still occur if a voltage surge is applied repeatedly. When a load which generates a surge, such as from a relay or solenoid valve, is directly driven, use a switch with a built-in surge absorbing element.. Since the type of fluid varies depending on the product, be sure to verify the specifications. The switches do not have an explosion proof rating. To prevent a possible fire hazard, do not use with inflammable gases or fluids. 5. Monitor the internal voltage drop of the switch. When operating below the specified voltage, it is possible that the load may be ineffective even though the pressure switch function is normal. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load. Supply voltage Internal voltage drop of switch > Minimum operating voltage of load [For air] 6. Use the switch within the specified flow rate measurement and operating pressure. Operating beyond the specified flow rate and operating pressure can damage the switch. [For water] 7. Use the switch within the specified flow rate measurement and operating pressure. Operating beyond the specified flow rate and operating pressure can damage the switch. Especially avoid the application of pressure through a water hammer, which is above the specification. <Examples of pressure reduction measures> a) Use a device such as a water hammer relief valve to slow the valve s closing speed. b) Absorb impact pressure by using an accumulator or elastic piping material such as a rubber hose. c) Keep the piping length as short as possible. 8. Design the system, so that the fluid always fills the detection passage. Especially for vertical mounting, introduce the fluid from the bottom to the top. 9. Operate within the flow rate measurement range. If operated outside of the flow rate measurement range, the Karman vortex will not be generated and normal measurement will not be possible. [Series PF2A7H]. Sudden increase in flow rate may destroy the flow sensor. Ensure to open/close the flow control valve not to exceed the maximum flow rate measurement values. Design and Selection Caution. Data from the flow switch is stored even after the power supply is turned off. The input data is stored in EEPROM so that the data will not be lost after the flow switch is turned off. (The data can be rewritten for up to one million times, and stored for up to 2 years.) 2. Accumulated flow rate is reset when it is turned OFF. Only the PF2A7H series (for air) will maintain, its accumulated flow rate value, even though the power supply is cut. Warning Mounting. Mount the switch using the proper tightening torque. When the switch is tightened beyond the specified tightening torque, it may be damaged. On the other hand, tightening below the specified tightening torque may cause the installation screws to loosen during operation. Thread Rc /8 Rc / Rc /8 Rc /2 Tightening torque N m 7 to 9 2 to 22 to 2 28 to Thread Rc / Rc Rc, /2 Rc 2 Tightening torque N m 28 to 6 to 8 8 to 5 8 to 5 2. Apply a wrench only to the metal part of the piping when installing the flow switch onto the system piping. Do not apply the wrench to any part other than the piping attachment or the switch may be damaged.. Monitor the flow direction of the fluid. Install and connect piping so that fluid flows in the direction of the arrow indicated on the body.. Remove dirt and dust from inside of the piping by means of air blow, before attaching to the switch. 5. Do not drop or bump. Do not drop, bump, or apply excessive impacts (9 m/s 2 ) while handling. Although the external body of the switch (switch case) may not be damaged, the switch inside could be damaged and cause a malfunction. 6. Hold the body of the switch when handling. The tensile strength of the cord is 9N and applying a greater pulling force than this can cause a malfunction. When handling, hold the body of the switch. 7. Do not use until you can verify that equipment can operate properly. Following mounting, repair, or retrofit, verify correct mounting by conducting suitable function and leakage tests after piping and power connections have been made. 8. Avoid the mounting orientation with the bottom of the body facing up. The switch can be mounted in any way such as vertically or horizontally, however, avoid the mounting orientation with the bracket on the bottom of the body facing upward. 7 PSE5 PSE5 ISE7/75/75H ZSE/ISE5/6 ZSE/ISE ZSE/ISE PSE55 PSE56 PSE2 PF2D PF2W PF2A ISA2 PSE

178 Series PF2A/PF2W Specific Product Precautions 2 Be sure to read before handling. Refer to page 7 for safety instructions.. Verify the colour and the terminal number when wiring. Incorrect wiring can cause the switch to be damaged and malfunction. Verify the colour and the terminal number in the instruction manual when wiring. 2. Avoid repeatedly bending or stretching of the lead wire. Repeatedly applying bending stress or stretching force to the lead wire will cause it to break.. Confirm proper insulation of wiring. Make sure that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.). Damage may occur due to excess current flow into a switch.. Do not wire in conjunction with power lines or high voltage lines. Wire separately from power lines and high voltage lines, and avoiding wiring in the same conduit with these lines. Control circuits including switches may malfunction due to noise from these lines. 5. Do not allow a load to short circuit. Although a switch indicates excess current error if a load is short circuited, all incorrect wiring connections such as power supply polarity cannot be protected. Take precautions to 7 Warning Warning avoid incorrect wiring. Mounting [For air] 9. Never mount a switch in a place that will be used as a step stool during piping. Damage may occur if an excessive load is applied to the switch.. Be sure to allow straight pipe length that is minimum 8 times the port size upstream and downstream of the switch piping. When abruptly reducing the size of piping or when there is a restriction such as a valve on the upstream side, the pressure distribution in the piping changes and makes accurate measurement impossible. Therefore, flow restriction measures such as these should be implemented on the downstream side of the switch. [For water]. Never mount a switch in a place that will be used as a step stool during piping. Damage may occur if an excessive load is applied to the switch. Especially when the switch supports the piping, do not apply a load of 5N m or more to the metal part of the switch. 2. Be sure to allow straight pipe length that is minimum 8 times the port size upstream and downstream of the switch piping. When abruptly reducing the size of piping or when there is a restriction such as a valve on the upstream side, the pressure distribution in the piping changes and makes accurate measurement impossible. Therefore, flow restriction measures such as these should be implemented on the downstream side of the switch. When used with the downstream side open, be careful of the cavitation that is prone to occur. Wiring Warning. When using a switch for high temperature fluid, the switch itself also becomes hot due to the high temperature fluid. Avoid touching the switch directly as this may cause a burn. Warning Usage Operating Environment. Never use in the presence of explosive gases. The switches do not have an explosion proof rating. Never use in the presence of an explosive gas as this may cause a serious explosion. 2. Mount the switch in a locations where there is no vibration greater than 98 m/s 2 or impact greater than 9 m/s 2.. Do not use in an area where surges are generated. When there are units that generate a large amount of surge in the area around a pressure switch, (e.g., solenoid type lifters, high frequency induction furnaces, motors, etc.) this may cause deterioration or damage to the switch s internal circuitry. Avoid sources of surge generation and crossed lines.. Switches are not equipped with surge protection against lightning. The flow switches are CE compliant, however they are not equipped with surge protection against lightning. Lightning surge protection measures should be applied directly to the system components as necessary. 5. Avoid using the switch in an environment where the likelihood of splashing or spraying of liquids exists. The switches are dustproof and splashproof, however avoid using in an environment where the likelihood of heavy splashing or spraying of liquids exists. Since the display unit of the remote type switches featured here is not dust or splashproof, the use in an environment where liquid splashing or spraying exists must be avoided. [For air] 6. Use the switch within the specified fluid and ambient temperature range. The fluid and ambient temperature range is to 5 C. Take measures to prevent the fluid from freezing when it is below 5 C, since this may damage the switch and lead to a malfunction. The installation of an air dryer is recommended for eliminating condensation and moisture. Never use the switch in an environment where there are drastic temperature changes even when these temperatures are within the specification. [For water] 7. Use the switch within the specified fluid and ambient temperature range. The fluid and ambient temperatures range for the switch is to 5 C (and to 9 C for high temperature fluid). Take measures to prevent the fluid from freezing when it is below 5 C, since this may cause damage to the switch and lead to a malfunction. Never use the switch in an environment where there are drastic temperature changes even when these temperatures fall within the specified temperature range.

179 Series PF2A/PF2W Specific Product Precautions Be sure to read before handling. Refer to page 7 for safety instructions. Digital Flow Sensors & Switches for Air/Water Series PF2A/PF2W Warning Warning Measured Fluid. Check regulators and flow adjustment valves before introducing the fluid. If pressure or flow rate beyond the specified range are applied to the switch, the sensor unit may be damaged. [For air] 2. The fluids that the switch can measure accurately are nitrogen and dry air. Please note that accuracy cannot be guaranteed when other fluids are used.. Never use inflammable fluids. The flow velocity sensor heats up to approximately 5 C.. Install a filter or mist separator on the upstream side when there is a possibility of condensate and foreign matter being mixed in with the fluid. The rectifying device built into the switch will be clogged up and accurate measurement will no longer be possible. [For water] 5. The fluid that the switch can measure accurately is water. Also, combination of equal parts water/ethylene glycol (5/5%) can be used if its temperature is high. Please note that accuracy cannot be guaranteed when other fluids are used. Detection principle of digital flow switch for air A heated thermistor is installed in the passage, and fluid absorbs heat from the thermistor as it is introduced to the passage. The thermistor's resistance value increases as it loses heat. Since the resistance value increase ratio has a uniform relationship to the fluid velocity, the fluid velocity can be detected by measuring the resistance value. To further compensate the fluid and ambient temperature, the temperature sensor is also built into the switch to allow stable measurement within the operating temperature range. Temperature compensation element Fluid velocity detection element Maintenance. Perform periodical inspections to ensure proper operation of the switch. Unexpected malfunctions may cause a possible danger. 2. Take precautions when using the switch for an interlock circuit. When a pressure switch is used for the interlock circuit, devise a multiple interlock system to prevent trouble or malfunction, and verify the operation of the switch and interlock function on a regular basis.. Do not disassemble or perform any conversion work on flow switches. This flow switch uses l/min as the flow rate indicator unit. The mass flow is converted and displayed under the conditions of C and. kpa. The conversion conditions can be switched to 2 C and. kpa with high flow type switches. Warning 6. Never use inflammable fluids. 7. Install a filter on the inlet side when there is a possibility of condensation and foreign matter being mixed with the fluid. If foreign matter adheres to the switch s vortex generator or vortex detector, accurate measurement will no longer be possible. Others. After the power is turned on, the switch s output remains off while a message is displayed. Therefore, start the measurement after a value is displayed. 2. Perform settings after stopping control systems. When the switch's initial setting and flow rate setting are performed, output maintains the condition prior to the settings.. Do not apply excessive rotational force to the display unit. The integrated type display unit can rotate 6. Rotation is controlled by the stopper; however, the stopper may be damaged if the display unit is turned with excessive force. [For air]. Be certain to turn on the power supply when the flow rate is at zero. Allow an interval of minutes after turning on the power, as there are some changes in the display. 5. Flow rate unit The switch measures at mass flow rates without being influenced by temperature and pressure. The switches use l/min as the flow rate indicator unit, in which the volumetric flow is substituted for mass flow at C and. kpa (nor). The volumetric flow rate at 2 C,. kpa, and 65%RH (ANR) can be displayed with the high flow rate type switches for air. Detection principle of digital flow switch for water When an elongated object (vortex generator) is placed in the flow, reciprocal vortexes are generated on the downstream side. These vortexes are stable under certain conditions, and their frequency is proportional to the flow velocity, resulting the following formula. f = k x v f: Frequency of vortex v: Flow velocity k: Proportional constant (determined by the vortex generator's dimensions and shape). Therefore, the flow rate can be measured by detecting this frequency. Fluid Vortex generator Contact SMC regarding the specifications for clean environment.

181 Series PF2A/PF2W Specific Product Precautions 5 Be sure to read before handling. Refer to page 7 for safety instructions. Digital Flow Sensors & Switches for Air/Water Series PF2A/PF2W -channel Flow Monitor Warning Handling. Do not drop, bump, or apply excessive impacts (98 m/s 2 ) while handling. Although the body of the flow monitor case may not be damaged, the inside of the flow monitor could be damaged and lead to a malfunction. 2. The tensile strength of the power supply/output connection cable is 5N and the sensor lead wire with a connector is 25N. Applying a greater pulling force than the applicable specified tensile strength to either of these components can lead to a malfunction. When handling, hold the body of the controller. Warning Connection. Incorrect wiring can damage the switch and cause a malfunction or erroneous switch output. Connections should be done while the power is turned off. 2. Do not attempt to insert or pull the flow rate sensor or its connector when the power is on. Switch output may malfunction.. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Malfunctions may occur due to noise from these other lines.. If a commercial switching power supply is used, make sure that the F.G. terminal is grounded. Warning Operating Environment. Our -channel flow monitor is CE marked, however, it is not equipped with surge protection against lightning. Lightning surge countermeasures should be applied directly to system components as necessary. 2. Our -channel flow monitor does not have an explosion proof rating. Never use pressure sensors in the presence of inflammable or explosive gases.. Enclosure "IP65" applies only to the front face of the panel when mounting. Do not use in an environment where oil splashing or spraying are anticipated. Caution Mounting The front face of the panel mount conforms to IP65, however there is a possibility of liquid infiltration if the panel mount adapter is not installed securely and properly.
