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.
- 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.
Power line connection is wrong.
(Phase Reversal Relay switch
can
’t be ON.)
-Connect the power line correctly.
Running lamp
extinguishes and
compressor stops
during
operation
but
resumes normal
operation
Switch with lamp
after a
period of time.
The product is installed in an
inappropriate location.
Ambient temperature is excessive.
- Improve ventilation condition and reduce the ambient
temperature as much as possible.
-Reset the protective circuit by referring to
“5-2 How
to reset the thermal relay and high pressure
switch.
” (Only IDFB55E,75E)
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.
-Reset the protective circuit by referring to

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.
-Reset the protective circuit by referring to
“5-2 How
to reset the thermal relay and high pressure
switch.
” (Only IDFB55E,75E)
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.
-Reset the protective circuit by referring to
“5-2 How
to reset the thermal relay and high pressure
switch.
