Wiring
Caution
(1) Use wiring cable with a cross section of 0.5 to 1.25mm
applied to the wires.
(2) Use electrical circuits which do not generate chattering within their contacts.
(3) Use voltages which are within +/-10% of the rated voltage. If a direct current power supply is
used and the response is important, the voltage should be within +/-5% of the rated value.
Voltage drop is the value at the lead wire when the coil is connected.
(4) If no solenoid surge is allowed in the electrical circuit system, mount a voltage suppressor in
parallel to the solenoid or, use the option with a surge voltage suppressor circuit.
(Surge voltage is generated even when the surge voltage suppressor circuit is used.) Please
consult with SMC for details.
Operating
Environment
Warning
(1) Do not use in an environment where corrosive gases, chemicals, sea water, water or steam
are present.
(2) Do not use in explosive atmospheres.
(3) Do not use in locations subject to vibration or impact.
(4) Do not use in areas where product is exposed to heat sources or in areas where the product
is exposed to radiant heat.
(5) Employ suitable protective measures in locations where there is contact with water droplets,
oil or welding spatter, etc.
Maintenance
Inspection
Warning
(1) Removal of product
Confirm that the valve temperature has dropped sufficiently before removing the product.
If touched inadvertently, there is a danger of being burnt.
a) Shut off the fluid supply and release the fluid pressure in the system.
b) Shut off the power supply.
c) Remove the product.
(2) Low frequency operation
Switch valves at least once every 30 days to prevent malfunction. The product requires periodic
inspection every 6 months for optimum operating conditions.
