Warning
Design / Selection
5. Surge voltage intrusion
With non-polar type solenoid valves, at times of sudden
interruption of the loading power supply, such as emergency
shutdown, surge voltage intrusion may be generated from
loading equipment with a large capacity (power consumption),
and the solenoid valve in a deenergized state may switch over
(see Figure 1).
When installing a breaker circuit for the loading power supply,
consider using a solenoid valve with polarity (with polarity
protection diode), or install a surge absorption diode between the
loading equipment COM line and the output equipment COM line
(see Figure 2).
6. Operation in a low temperature condition
Take appropriate measures to avoid freezing of drainage,
moisture etc. in low temperature.
7. Mounting orientation
Mounting orientation is free.
Mounting
1. Operation manual
Install the products and operate them only after reading the
operation manual carefully and understanding its contents. Also,
keep the manual where it can be referred to as necessary.
2. Ensure sufficient space for maintenance activities.
When installing the products, allow access for maintenance.
3. Tighten threads with the proper tightening torque.
When installing the products, follow the listed torque specifications.
4. If air leakage increases or equipment does not
operated properly, stop operation.
Check mounting conditions when air and power supplies are
connected. Initial function and leakage tests should be performed
after installation.
5. Painting and coating
Warnings or specifications printed or affixed to the product
should not be erased, removed or covered up.
Please consult with SMC before applying paint to resinous parts,
as this may have an adverse effect due to the solvent in the paint.
