6.1 Cause and countermeasure of errors
Should any problem occur, inspect the following table, and if the problem cannot be solved, shut off the
power supply and then contact an SMC authorized dealer for further instructions.
Problem
Probable Causes
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.
- Perform proper connection on the power cord and
plug.
The ground fault circuit
interrupter is not turned ON.
- Check the capacity of the ground fault circuit
interrupter.
- 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.
Remote operation signal is OFF.
(in case of Option T)
-Confirm the remote operation signal connection or
signal setting.
After a while,
operation stops and
running lamp goes
out.
(Protective device has
been activated.
Reset the protective
device referring to
“5-2 How to reset the
thermal relay and high
pressure switch”.)
The product is installed in an
inappropriate location. Ambient
temperature is excessive.
- Improve ventilation condition and reduce the ambient
temperature as much as possible.
The ventilation port is obstructed
by a wall or clogged with dust.
- Keep the product 600mm or more away from the
surrounding walls.
- Clean the ventilation ports once every month.
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.
The fluctuation of the power
supply voltage is too large.
- Install a power supply transformer or use a different
power supply to provide appropriate voltage.
(Power supply voltage fluctuation should be kept
/-10% and should not be continuous.)
After a while,
operation stops.
Running lamp keeps
on.
(Overload relay on
refrigeration
compressor has been
activated.
Turn off the switch
with lamp and wait for
a while until the
overload relay is
recovered
automatically.)

The compressed air temperature
is excessive.
- 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 after-cooler after the air compressor to
reduce the temperature.
The fluctuation of the power
supply voltage is too large.
- Install a power supply transformer or use a different
power supply to provide appropriate voltage.
- The fluctuation of the power supply voltage should be
kept /-10% of the rated voltage.
The built-in overload relay of the
compressor for refrigeration has
started.
- Check the product was not restarted within 3 minutes
after being stopped.
