6 Features & Benefits Why Proptional Technology? The Difference Between Open Closed Circuit Control Standard pressure regulats go a long way towards meeting customers needs. In most cases these regulats wk well in general pneumatic and automation applications. However, sometimes the application calls f me precise pressure control. The effects of time, cycling, input, back pressure pressure and flow variation can all cause inconsistencies in pneumatic systems. Proptional Regulats are designed to eliminate those inconsistencies. Open Control Circuit In a nmal pressure regulated control system, the inlet pressure (p1) is converted into the output pressure (p2) by the regulat. The set pressure (set value) is usually manually set by adjusting the control knob and in nmal circumstances the regulat maintains the output pressure (actual value). No facility f moniting the output pressure is provided and there is consequently no way of checking that the set value and the actual value are the same. Also, no account is taken of external influences such as air consumption by the system, which can drastically alter the actual value. P3HP Series Proptional Regulat Closed Loop Control Circuit The input signal (Electronic Control Signal) is converted into the output value (P2 Output Pressure). This output value is continuously measured and compared with the input signal. If they are different, the unit adjusts the output value to crespond to the set value, to close the loop. Proptional Pressure Regulats The P3HP provides all the advantages of a closed circuit regulated system. When a set value is defined via the input signal (e.g V), the pressure regulat sets the cresponding output pressure (e.g PSI/0-10 bar). At the same time the integrated pressure sens measures the actual pressure at the unit s outlet (actual value). If the electronic regulation system finds that the actual value has deviated from the set value, it immediately crects the actual value. This is a continuous process ensuring fast, accurate pressure regulation. Typical Application in Automotive Body in White Welding Pressure Control 6 Parker Hannifin Cpation

10 Technical Infmation Advanced Functionality Pilot Valve Protection When the required output pressure can not be achieved due to lack of input pressure, the unit will open fully and will display NoP. Approximately every 10 seconds the unit will retry. The output pressure will then be approximately equal to the inlet pressure. As soon as the input pressure is back on the required level, the nmal control function follows. Safety Exhaust Should the control signal fall below 0.1 volts, the valve will automatically dump downstream system pressure. Fail-safe When the supply voltage drops below 19 VDC, the electronic control reverts to the fail-safe mode. The last known output pressure is maintained at approximately the same level, depending upon air consumption. The digital display indicates the last known pressure setting. When the supply voltage is reinstated to the crect level, the valve moves from the fail-safe mode and the output pressure immediately follows the control signal requirement. The display indicates the actual output pressure. P3HP Series Proptional Regulat Input Protection The unit has built-in protection against failure and burnout resulting from increct input value, typically: The 24 VDC supply is increctly connected to the setpoint input, the display will show OL, as an overload indication. The unit will need to be rewired and, when crectly connected, will operate nmally. The overload indicat OL will also appear should the wrong input value be applied the wrong input value be programmed: (0-10 V instead of 4-20 ma conversely 4-20 ma rather than 0-10 V). To crect this, a different set point value should be input, the unit reprogrammed to crect the set point value acceptance (via parameter 4). Response Times To fill volume of 6.1 in 3 (100 cm 3 ), connected to the outlet of the regulat: Pressure increase from 2 to 4 bar (30 to 60 PSI)...30 msecs Pressure increase from 1 to 6 bar (15 to 90 PSI) msecs Pressure decrease from 4 to 2 bar (60 to 30 PSI)...60 msecs Pressure decrease from 6 to 1 bar (90 to 15 PSI) msecs Settings The regulat is pre-set at the facty.

20 Features Introduction The P3P-R range of Electro-pneumatic Pressure Regulats are offered in 1/8", 1/4" and 1/2" pt sizes. By means of an integrated electronic control system and pulse width modulated solenoid valves, the P3P-R Electro-pneumatic Pressure Regulat controls the output pressure proptionally to an analog electrical signal. A high degree of precision is achieved by means of internal feedback through an integrated pressure sens.

21 Operation P3P-R Series Pressure Regulat 1/8" EP Transducer Description of Operation 1/8" EP Transducer The P3P-RP EP Transducer allows regulation of the outlet pressure proptional to an electrical control signal. It comprises an integrated closed loop electronic control and two pulse width modulated (PWM) 2-way solenoid valves (C). The pressure sens (B) measures the outlet pressure and provides a feedback signal to the differential amplifier. Any difference between the control signal and the feedback signal is converted to a digital signal to energize the coil of one the other 2-way valves. This is accomplished without overshoot. The control signal can be a voltage (0-10VDC) a current (4-20mA). The inlet of the filling valve is connected directly with the inlet (P) of the transducer. When energized this valve will increase the pressure at the outlet (A). When the exhaust valve is energized, the pressure at the outlet will decrease. The pressure will be exhausted through a discharge ifice (E) located between the cover and the body and directly fed to atmosphere without a silencer.

22 Operation P3P-R Series Pressure Regulat 1/4" & 1/2" Regulat Description of Operation 1/4" & 1/2" Regulat The P3P-RJ Series is a family of electrically remotecontrolled pneumatic pressure regulats with closed loop integrated electronic control. It allows regulation of the outlet pressure proptional to an electrical control signal. The P3P-R regulat comprises a pilot-operated pneumatic pressure regulat, where the pilot chamber is fed by one the other of two pulse width modulated (PWM) 2-way solenoid valves (C). The pressure sens (B) measures the outlet pressure of the regulat and provides a feedback signal to the amplifier. Any difference between the control signal and the feedback signal is converted to a digital signal to energize the coil of one the other 2-way valves to crect the position of the regulat. The control signal can be a voltage (0-10VDC) a current (4-20mA). The inlet of the filling valve is connected directly to the main inlet (P) of the regulat; when energized this valve will fill the pilot-chamber f increasing the pressure at the outlet (A) of the regulat. When the other exhaust valve is energized (reduction of pressure at the outlet (A) of the regulat), the pressure of the pilot-chamber will be exhausted through a discharge ifice located between the cover and the body and directly fed to the atmosphere without a silencer. The exhaust of the main regulated pressure will be made through the quick exhaust (E). The use of a conventional silencer is recommended. Both solenoid valves assure the filling emptying of the pilot-chamber in der to increase decrease the pressure at the outlet of the regulat. In the rest position, all pts are blocked.

23 Operation P3P-R Series Pressure Regulat 1/8", 1/4" & 1/2" Schematics 1/8" EP Transducer with Integrated Pressure Sens, and Output Signal Module Through a differential amplifier, the electronic control unit receives both the control signal (set pressure) and the feedback signal from the sens (outlet pressure). Any difference between the two amplifier inputs results in a cresponding output which drives the appropriate 2-way pulse width modulated solenoid valve. The closing and opening of these pilots crects the outlet pressure. An integrated output signal module allows the utilization of voltage and current output signals (0-10VDC, 4-20mA) proptional to the outlet pressure, a voltage output signal (0-10VDC) and an Alarm Output Signal 0/24VDC 24/0VDC. Adjustable Positive Alarm Signal (0V healthy, 24VDC alarm) Negative Alarm Signal (24VDC healthy, 0V alarm) can be used to indicate a drop in the inlet pressure. The minimum span is 3 PSIG (0.2 bar) and the maximum span is 30% of the inlet pressure. Example: 30 PSIG f 100 PSIG inlet 1/4" & 1/2" version with Integrated Pressure Sens without Output Signal Module Similar principle of operation as previously explained, but without output signal module.

A vast range of senss can be used such as proximity, level pressure senss etc., provided the regulation system responds proptionally to the pressure. Example: Opening of a large valve through a pneumatically driven actuat. If the angle of rotation of the gate is proptional to the pressure, the P3P-R can be controlled by a proximity sens.

32 Basic Features PAR -15 Series Valves Regulating Valve PAR -15 Series Features PAR TM -15 (Patent No. 4,630,632) is a unique 3-Way, programmable, air regulating valve that functions as a precise, high-flow, multi-purpose regulat. Signals from a computer, programmable controllers from simple electrical switches, fed to the valve s four solenoids, control the division of a single inlet pressure into any one of fifteen equally spaced output pressures. The valve s response is instant and repeatable, reducing the need f expensive feedback controls. It goes far beyond the capabilities of conventional controls by providing a limitless range of application possibilities including cylinder pressure/stroke control, clamping, retracting, approach, flow, and impact. PAR TM -15 eliminates shock absbers, increases tool life, saves air, and reduces wkpiece damage. Full flow capacity f direct air device operation. Quick, full flow exhaust. Instantly repeatable response. Air saving design, close crossover, non-constant bleed. Wide range of discrete output pressures. Nmally closed nmally open operats. Compatible with computers and programmable controllers with digital solid state relay outputs. Meets NEMA 4 standard (6-Pin option only). Body Flow X1 C C EXH X2 C Flow Circuit Board Solenoid Divider Piston Washer Poppet Spring Poppet Guide Electropneumatic System A conventional system is usually composed by several electronic and pneumatic components as shown on the schematic. The cylinder which is moving a load is operated with a pilot valve which receives the instructions from an electropneumatic transducer. The transducer converts electronic signals to pneumatic signals. These electronic signals are usually of an analog type, but controllers/computer microprocesss send digital signals as outputs, therefe, a digital to analog signal converter is required. The simplified schematic with the PAR TM -15 is reduced to fewer components since the PAR TM -15 takes the place of the digital to analog converter, the electropneumatic transducer, and the pilot valve. The benefits being fewer components, and less maintenance and downtime.

34 Solenoid Operated Valves PAR -15 Series Valves 3-Way, 3-Pt, 2-Position Application Pneumatic systems operating under multiple pressures, and requiring almost instantaneous pressure changes are good application cases f the PAR -15. Usually the me pressures needed f a particular operation, the easier it is to justify the valve, since it will take the place of several pneumatic regulats and select valves. Among the most common applications are brakes and clutches, painting, printing feeds and tension, robotics, and spot welding. Other Applications: Air Chucks Air Cylinder Control Air Winches Blow Molding Control Contact Fce Control Convey Control Die Cushioning Dynamic Braking Operation No Enclosure Fuel Control Hopper Control Robot Gripper Control Valve Positioning Variable Clamping Variable Pressure Processing Tque Control Wire Tensioning Four solenoids are controlled by on/off signals that selectively divide any input pressure into any one of 15 equally spaced pressures plus zero. See the truth table. Model Selection Infmation NEMA 4 Enclosure 6-Pin Connect Full flow exhaust permits instant reduction to any lower selected pressure zero. High relief capacity quickly vents downstream overpressure. The output pressure will begin to change within 20 milliseconds after a change in the electrical input to one me of the solenoids. However, the time which elapses until the output pressure reaches the new level will depend upon the volume of air, the size of the connection from the PAR -15 valve and the magnitude of the pressure change. A small regulat may be used to feed the external pilot pt X1 on units with nmally closed solenoid operats X2 on units with nmally open solenoid operats. The PAR -15 valve will then divide this pressure independent of mainline supply pressure so long as the pilot regulat is set to a pressure below the mainline supply pressure. A regulated external supply will eliminate the effects of fluctuating mainline pressures. (NOTE: A regulat placed upstream of the inlet also eliminates the effects of fluctuating pressures). The PAR -15 is available with two types of output pressure regulation: increasing output and decreasing output. In the increasing output pressure regulation type, nmally closed solenoid operats are used to divide the input pressure into 15 equal steps, ranging from 0 PSIG (all solenoid operats de-energized) to full line pressure (all solenoid operats energized). With the decreasing output pressure regulation type, nmally open solenoid operats are used to divide the input pressure into 15 equal steps, but starting with full line pressure (all solenoid operats de-energized) and ending with 0 PSIG (all solenoid operats energized).

36 Technical Infmation Narrow Band Control The PAR -15 can also be used to provide a narrower band of output pressures with the lowest selected pressure greater than zero. EXAMPLE: Assume valve with nmally closed solenoids. Customer desires to divide a range from 25 PSIG to 100 PSIG into 15 increments of 5 PSIG each. This is done by applying 100 PSIG to the external pilot supply pt X1 and 25 PSIG to the pilot exhaust pt X2. Two 1/8 inch relieving regulats are required. The addition of one 3-Way nmally closed solenoid operated valve allows the additional selection of 0 PSIG. These are connected as shown in the diagram. The relieving regulats set the upper and lower band limits. With a nmally closed PAR -15 valve, zero output pressure may be selected by simultaneously de-energizing the 3-Way valve and the PAR -15 valve solenoids. With a nmally open PAR -15 valve, zero output pressure may be selected by simultaneously de-energizing the 3-Way valve and energizing the PAR -15 valve solenoids. Cascading Narrow Band Control Diagram UPPER BAND LIMIT Two PAR -15 s can also be used in conjunction to provide 240 steps (versus 15 steps from one valve), therefe me output pressures. See diagram. Connect the outlet pt marked OUT of the valve upstream to the 1/8" pt marked C of the valve downstream. A pt/pipe reducer(s) must be used to accomplish this task. If desired, a pressure gauge can be installed between these two points. A gauge isolat should be used to protect the gauge from pulsating pressures. Connect the outlet pt marked OUT of the valve downstream to the supply side of the system requiring multiple pressures. If desired, a pressure gauge can be installed downstream of the outlet pt. A gauge isolat should be used to protect the gauge from pulsating pressures. DO NOT PLUG THE 1/8" PORTS MARKED C AND X2 ON THE VALVE UPSTREAM AND X2 ON THE VALVE DOWNSTREAM.
