cause
Remedy
Although the
switch with lamp
is turned on, the
lamp does not
light up and the
product does not
start operating.
The power supply cable has been
loosened or disconnected.
- Reconnect it firmly.
The ground fault circuit interrupter
is not turned on.
Check the capacity of the ground fault circuit interrupter.
- Check the product was not restarted within 3 minutes after
being stopped.
- Turn on the ground fault circuit interrupter and try to
operate.
If the ground fault circuit interrupter turns back off, the
insulation failure of the product is suspected. Turn off the
power supply and contact SMC.
[Ground fault circuit interrupter (Option R)]
- The ground fault circuit interrupter is turned off at the time of
shipment. Turn on it before starting operation.
- Operation cannot be recovered automatically by turning on
the ground fault circuit interrupter. Be sure to eliminate the
cause before turning it on. Restarting without solving the
cause can cause a serious accident.
The 3-phase power supply is
connected incorrectly.
- Swap over the connection of 2 of the 3 wires (R and T
phases).
The external switch for remote
operation is not turned on.
- Turn on the external switch.

high.
- Increase the cooling capacity of the facility water facility,
and decrease the cooling water temperature.
- Refer to “5.2 Reset of protective equipment” and reset the
protective circuit.
The compressed air temperature is
too high.
- Improve the ventilation in the location where the air
compressor is installed, or decrease the ambient
temperature to allow the discharge air temperature of the
air compressor to go down.
- Install an aftercooler after the air compressor to reduce the
temperature.
- Refer to “5.2 Reset of protective equipment” and reset the
protective circuit.
