If suction flow changes, the vacuum pressure will also be changed. Normally this relationship is expressed in ejector standard operating pressure use. In graph, Pmax is max. vacuum pressure and Qmax is maximum suction flow. The values are specified according to catalog use. Changes in vacuum pressure are expressed in the below order.. When ejector suction port is covered and made airtight, suction flow becomes zero and vacuum pressure is at maximum value (Pmax). 2. When suction port is opened gradually, air can flow through, (air leakage), suction flow increases, but vacuum pressure decreases. (condition P and Q) 3. When suction port is opened further and fully opened, suction flow moves to maximum value (Qmax), but vacuum pressure is near zero (atmospheric pressure). s described above, the vacuum pressure changes when the suction flow changes. In other words, when there is no leakage from the vacuum () port, the vacuum pressure can reach its maximum, but as the amount of leakage increases, the vacuum pressure decreases. When the amount of leakage and the max. suction flow become equal, the vacuum pressure becomes almost zero. In the case when ventirative or leaky work should be adsorbed, please note that vacuum pressure will not rise.

How to Replace the Filter When adsorption performance decreases or when there is delay in response time due to clogging of the filter, stop the operation and replace the filter with a new one. ) Hold the -port assembly with your fingers, turn it 45 degrees in the counterclockwise direction and pull it out. For the straight type fitting, it can be removed with a hexagon wrench (width across flats:.79 inch (2 mm)) by inserting it until it touches the end and turning it 45 degrees in the counterclockwise direction. (When using a wrench, do not turn it more than 45 degrees by force as this will damage the hexagon hole which is made of resin.) 2) Remove the filter element from the removed filter case, and mount a new filter element into the case. 3) Confirm that the gasket at the -port assembly mounted part of the body is not displaced and that it has no foreign matter stuck to it. 4) Insert the tab of the -port assembly along the groove, and rotate it approx. 45 degrees in the clockwise direction while pressing it gently until it stops. (Mount the filter case in the direction specified in the figure. If it is mounted with the tab downwards, it will interfere with the floor when the unit is installed on the floor.)

18 Series ZB Specific Product Precautions Be sure to read the below before handling. Refer to page 2 for Safety Instructions. For acuum Equipment Precautions, refer to Handling Precautions for SMC Products (M-E3-3) and Operation Manual. The Operation Manual can be downloaded from the SMC website: alve/ alve. How to use the latching-type supply Our latching-type solenoids are fitted with a self-detaining mechanism. Its construction features an armature inside the solenoid which is set or reset using spontaneous energization ( ms or greater). Therefore, continuous energization is not required. <Special care must be taken for the latching type.>. void using this product with a circuit which electrifies both the set and reset signals simultaneously. 2.The minimum energization time required for self-detaining is ms. 3. Contact SMC when using this product in locations where there are vibration levels of 98 ft/s 2 (3 m/s 2 ) or above or highly magnetic fields. No problems arise in normal usage or locations. 4. This supply retains the reset position (stops generation of vacuum) at the time of shipment. However, it may alter to the set position during transportation or due to vibration when mounting the supply. Therefore, confirm the home position either manually or with power supply prior to use. How to Use the alve/ alve Plug Connector Wiring Specifications Wiring should be connected as shown below. Connect with the power supply respectively. N.C. SOL. C Lead wire colors ( ) Black (+) Red Latching type (DC positive common) Lead wire colors Set ( ) Black SOL. C COM.

Operation Indicator light -C ON Generates vacuum. Orange OFF Stops generation of vacuum. If the supply is latching type, continuous energization is not necessary because it maintains the switching position with momentary energization for at least msec. Depending on the conditions, continuous energizing may cause operation failure such as ON operation failure due to operation voltage increase due to coil temperature rise. When continuous energizing is necessary, the energizing time shall be minutes or shorter. Before the next operation, the solenoid shall be de-energized (both side and B side OFF) for longer than the energized time. Duty ratio shall be 5% or less. 2. void energizing the supply /release for long periods of time. If a supply /release is energized for a long period of time, the coil will get hot and the performance may be reduced. dditionally, the peripheral equipment in close proximity may also be badly affected. Use a latching-type supply when the supply /release is energized continuously or when the duration of the energization is longer than the non-energized period each day so that periods of energization can be shortened. But, do not energize the coil on both and B sides simultaneously when using the latching type. Continuous energization of the supply /release shall be minutes or shorter in duration and the energization period shall be shorter than the non-energized period. Duty ratio shall be 5% or less. Take measures for any heat radiation so that the temperature is within the range of supply /release general specifications when the is mounted on the control panel. Please pay special attention to any temperature increases when a manifold type with 3 stations or more is energized continuously or when 3 individual units are placed in close proximity.

19 Handling of the -Port ssembly. The construction of the -port assembly is such that it can be attached or detached at a touch. When mounting or removing, turn the case completely until it reaches the position where it cannot turn any further. Otherwise, the port may come off or be damaged. 2. If it is mounted on the floor, remove the manifold base once from the installation position and lift the body to perform mounting and removal work so that the mounting and removal work can be performed more easily. 3. If the one-touch fitting is the straight type, a hexagon wrench (width across flats:.79 inch (2 mm)) can be used. The hexagon hole is resin, so it can be broken if excess torque is applied. Do not apply torque of.33 in Ib (.5 N m) or more. Do not apply any more torque when it reaches the position where it cannot be turned further. 4. When inserting or removing a tube into or out of the one-touch fitting, hold the one-touch fitting body with your fingers. Otherwise, excessive force applied to the -port assembly or one-touch fitting assembly, causing air leakage or damage, etc. Especially if load is applied in the bending direction against the axial direction of the filter case, the case may be broken. Series ZB Specific Product Precautions 2 Be sure to read the below before handling. Refer to page 2 for Safety Instructions. For acuum Equipment Precautions, refer to Handling Precautions for SMC Products (M-E3-3) and Operation Manual. The Operation Manual can be downloaded from the SMC website: Operating Pressure. Use the product within the specified supply pressure range. Operation over the specified supply pressure range can cause damage to the product. Especially for the vacuum pump system with the adsorption nozzle, the pressure inside the product can increase due to the release pressure. Use the proper pressure and make sure that the adsorption part is not clogged. Piping to the Manifold Base. For the port of the manifold base, use a fitting whose maximum bore size of the outside dimension is smaller than ø.47 inch (ø2 mm). Otherwise, the exterior of the fitting will interfere with the manifold base installation face. Recommended fittings: KQ2S6-S, KQ2S4-S, KJS6-S 2. When mounting or removing the fittings, etc. to and from the manifold base, hold the manifold base with a wrench. If the ejector/vacuum pump system is held, it may cause air leakage or damage to the product. 3. The tightening torque for each thread is shown below. /8 ( port): 6.95 to in Ib (7 to 9 N m) M5 (, port): fter tightening by hand, increase the tightening by about /6 turn with a tightening tool. Ejector Exhaust. The exhaust resistance should be as small as possible to obtain the full ejector performance. There should be no shield around the exhaust port for the silencer exhaust specification. For the port exhaust specification, the back pressure increase should be.7 psi (.5 MPa (5 kpa)) at maximum, as exhaust resistance is generated with some piping bore sizes and piping lengths. s a guide, keep the length not more than 39.4 inch ( mm) when the tube inside diameter is If the sound absorbing material is clogged, it will cause a reduction in the ejector performance. In particular, if it is used in a dusty environment, not only the suction filter, but also the silencer can be clogged. It is recommended to replace the sound absorbing material periodically referring to the figure below. Replacement Procedure ) Turn the body upside down. pply a watchmaker s screwdriver or your finger to the notch, and slide the silencer cover in the direction indicated by the mark. 2) It makes a click sound and the hook is disconnected. Put your nail to the part and remove the cover. 3) Catch the sound absorbing material and pull it out using a watchmaker s screwdriver. 4) Insert a new sound absorbing material, and mount the cover by the reverse procedure of the disassembly procedure for reassembly.
