12 Series ZA Specific roduct recautions e sure to read before handling. Refer to est neumatics No. for Safety Instructions and acuum Equipment recautions. Warning. Avoid energizing the solenoid valve for long periods of time. If a solenoid valve is energized for a long period of time, the coil will get hot and the performance may be reduced. Additionally, the peripheral equipment in close proximity may also be badly affected. Use a low wattage solenoid valve when the solenoid valve is energized continuously or when the duration of the energization is longer than the non-energized period each day. eriods of energization can be shortened by using a latching type solenoid valve. ut, do not energize the coil on both A and sides simultaneously when using the latching type. Continuous energization of the solenoid valve should be less than minutes in duration and the energization period should be shorter than the non-energized period. Take measures for any heat radiation so that the temperature is within the range of solenoid valve specifications when the solenoid valve is mounted on the control panel. lease pay special attention to any temperature increases when a manifold type with stations or more is energized continuously or when three individual units are placed in close proximity.. Use the vacuum equipment within the operating supply pressure range. When the operating with a lower supply pressure, the vacuum performance will be reduced and the poppet valve will cause malfunction. Never use the vacuum equipment more than the operating supply pressure range as this may cause damage to the product resulting in potentially dangerous operation.. Suspension of operation for long periods of time lease use caution as detailed below when the vacuum equipment is turned off for periods in excess of hours. e sure to turn off the pressure supply to the vacuum equipment. lease observe this precautions as the supply pressure will be applied for a extra period of time due to the line pressure increase and may result in damage to the vacuum equipment. e sure to turn off the power supply to the solenoid valve and the pressure switch. lease observe this precautions as any heat generated due to the length of energization time may seriously affect the vacuum equipment and peripheral equipment resulting in potentially dangerous operation.. Exhaust port (EXH port) on the vacuum ejector lease check the exhaust port (EXH port) on the vacuum ejector, so that any exhaust resistance will not be increased due to insulating materials or restrictions in the piping. The exhaust resistance may reduce the ejector s performance. Additionally, never use this product in an application where the exhaust port is blocked when detaching a workpiece. This misuse may result in possible damage to the product.. acuum release flow adjusting needle Adjust the vacuum release flow adjusting needle from the fully closed to the open state by /8 to / turns to detach a workpiece completely during the ON time of a release valve. Do not supply compressed air while the vacuum release flow adjusting needle is adjusted. Securely lock it with a lock nut after adjustment. Design and Selection Warning. How to use the latching type solenoid valve Our Latching type solenoid are fitted with a self-detaining mechanism. Its construction features an armature inside the solenoid which is set or reset using spontaneous energization. (0 ms or greater) Therefore, continuous energization is not required.

Avoid using this product with a circuit which electrifies both the set and reset signals simultaneously.. The minimum energization time required for self-detaining is 0 ms.. lease contact us when using this product in locations where there are vibration levels of 0 m/s or above or highly magnetic fields. No problems arise in normal usage or locations.. This valve retains the reset position (Flow path: A R) at the time of shipment. However, it may alter to the set position during transporatation or due to vibration when mounting the valve. Therefore, confirm the home position either manually or with power supply prior to use. 7. Suction filter This suction filter is dedicated to the ZA series. Avoid using it for other purposes. Red

13 Series ZA Specific roduct recautions e sure to read before handling. Refer to est neumatics No. for Safety Instructions and acuum Equipment recautions. Warning Mounting. When the body is mounted, tighten with a torque of 0. ± 0.0 N m. Using excessive torque may cause damage to the body.. When the filter assembly is mounted, tighten with a torque of 0.07 ± 0.0 N m. Using excessive torque may cause damage to the filter case. Operating Environment Warning. Suction filter The filter case of this suction filter is made of nylon. The product will be damaged if solvents such as alcohol or chemicals are splashed on it. Avoid using it in an atmosphere where such solvents are present.
