5 Port Solenoid Valve Series SV1000/2000/3000/4000 Failure to do so may cause damage or malfunction.
Under certain conditions, the exhaust of the vacuum ejector may generate intermittent noises, and vacuum pressure may be uneven.
Fluctuations in pressure may cause malfunction. 22 Smooth Cylinder Auto Switch Precautions 1 Be sure to read befor handling. Design & Selection Warning In the same way, when operating under a specified voltage, although an auto switch may operate normally, the load may not operate.
The range may vary greatly (as much as 30%) depending on the operating environment.

Auto switches may malfunction if a shielding plate is not used.
This may cause deterioration of the insulation or swelling of the potting resin inside switches and may cause a malfunction. 141 Auto Switch Precautions 4 Be sure to read before handling. Maintenance Warning 1.
(Tolerance 30%) Hysteresis may fluctuate due to the operating environment.
Under certain conditions, the exhaust of the vacuum ejector may generate intermittent noises, and vacuum pressure may be uneven.
This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress. 6. Avoid incorrect wiring.
Although the body of the switch may not be damaged, the inside of the switch could be damaged and cause a malfunction. 2. Do not carry a rotary actuator by the auto switch lead wires. Never carry a actuator by its lead wires. This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress. 3.
Even though an auto switch operates normally, the load may not operate. Load In the same way, when operating below a specified voltage, although an auto switch may operate normally, the load may not operate. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load.
This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress. 3. Mount switches using the proper tightening torque. If a switch is tightened beyond the range of tightening torque, the mounting screws, mounting brackets or switch may be damaged.
Otherwise, the life of the contacts may be reduced. (They may stay on continuously.) Further, even in the case of a type having an internal contact protection circuit (D-B54, D-B64, D-B59W), if the length of the wiring to the load is extremely long (30m or more) and a PLC having a large rush current is used, confirm whether a contact protection box may be necessary.
Air leakage may be happened, depending on the position in which a rod seal is fitted.
Damage may occur due to excess current flow into a switch. 4.
If using other screws, switch may be damaged.
Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may cause faulty operation. Also, scratches or gouges in the piston rod may lead to damaged seals and cause air leakage. 2.
This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress. 6. Avoid incorrect wiring.
This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress. 3. Mount switches using the proper fastening torque. 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 a switch. 4.
