3 Port Solenoid Valve for Fluid Control/Precautions 3
Be sure to read this before handling.
For detailed precautions on each series, refer to the main text.
1. As a rule, use electrical wire with a cross sec-
tional area of 0.5 to 1.25m
m
2
for wiring.
Furthermore, do not allow excessive force to
be applied to the lines.
2. Use electrical circuits which do not generate
chattering in their contacts.
3. Use voltage which is within
±10% of the rated
voltage. In cases with a DC power supply
where importance is placed on responsive
-
ness, stay within
±5% of the rated value. The
voltage drop is the value in the lead wire sec
-
tion connecting the coil.
4. When a surge from the solenoid affects the
electrical circuitry, install a surge absorber,
etc., in parallel with the solenoid.
Or, adopt the option that comes with the sur
-
ge voltage protection circuit. (However, a sur
-
ge voltage occurs even if the surge voltage
protection circuit is used. For details, please
contact SMC.)
