1. Surface treatment is applied to the product to
improve corrosion resistance. There may be spot

condition, but there is no problem in use.
condition, but there is no problem in use.
Wiring
Warning
1.
The controller starts its output the moment the power switch is
turned ON. Be aware that even if the power switch is turned
OFF, power is connected to the terminal block.
Caution
1.
Make sure that the power supply voltage to be input matches
the voltage in the controller’s specifications. The power supply
voltage that has been input becomes the voltage that is output
to the solenoid valves.
2.
Connect a ground that is rated Class 3 or greater to the power
supply terminal block’s FG.
3.
If the power source is DC, use caution to its polarity. If the
polarity is incorrect, it may result in a malfunction or damage.
4.
For details, refer to the separate Operation Manual.
5.
The solenoid valve mounted on the controller should be
equipped with a surge voltage suppressor.
Operating Environment
Warning
1.
Operate under conditions that are free of vibration and impact.
2.
Operate in an ambient temperature range between 0
°
C and
50
°
C.
3.
Operate in an ambient humidity range between 45% to 80%
(no condensation allowed).

Operating Environment
Warning
1. Do not use in an atmosphere having corrosive
gases, chemicals, sea water, water vapor, or where
there is direct contact with any of these.
2. Do not use in explosive atmospheres.
3. Do not use in locations subject to vibration or impact.
4. Do not use in locations where radiated heat will be
received from nearby heat sources.
5. Employ suitable protective measures in locations
where there is contact with oil or welding spatter,
etc.
Maintenance
Warning
1. Removing the product
The valve becomes hot depending on the fluid temperature.
Confirm that the valve temperature has dropped sufficiently
before performing work. If touched inadvertently, there is a
danger of being burned.
1. Shut off the fluid supply and release the fluid pressure in the
system.
2. Shut off the power supply.
3. Remove the product.
2. Low frequency operation
Switch valves at least once every 30 days to prevent malfunc-
tion. Also, in order to use it under the optimum state, conduct a
regular inspection once a half year.
3. Disassembly
Do not disassemble for purposes other than the main valve
replacement, or malfunction may occur.
Refer to the Disassembly/Assembly Procedure on page 8 for
the replacement of the main valve.
Caution
1. Filters
1. Be careful regarding clogging of filters.
2. Replace filter elements after one year of use, or earlier if the
pressure drop reaches 0.1 MPa.
2. Storage
In case of long term storage after use, thoroughly remove all
moisture to prevent rust and deterioration of rubber materials
etc.
3. Exhaust the drainage from an air filter periodically.
