5.1 Troubleshooting 

If any error is found in the product, investigate the following points. If the error cannot be solved, turn off the 

power supply and contact your local supplier or SMC sales representative. 

Trouble 

Possible 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. 

Running lamp 

extinguishes   

and compressor 

stops during 

operation but 

resumes normal   
operation   
illuminating the 
lamp after 
aperiod 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. 

The  ventilation  port  is  obstructed 
by a wall or clogged with dust. 

- Keep the product 60cm 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. 

- The fluctuation of the power supply voltage should be kept 

/-10% of the rated voltage. 

The evaporation 
thermometer is 
over the green 
area without hot 
air coming from 
the ventilation   
port (exhaust 
port). 
(The compressor 
for refrigeration 
has stopped  with 
the lamp lit up. 

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 60cm or more away from the 
surrounding walls. 
- Clean the ventilation ports once every month. 

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 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. 

- 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.
