5.1 Troubleshooting
Should any problem occur, inspect the following table, and if the problem cannot be solved, shut off the power supply
and then contact one of our sales offices for further instructions.
Problem
Probable causes
Action
Power cord or plug is in loosening
state or completely pulling out.
Perform proper connection on the power cord and plug.
Air dryer does not
operate and running
lamp does not light on,
even switch is ON.
Circuit breaker is OFF.
Confirm whether the proper capacity of the circuit
breaker is used.
It is not possible to restart the air dryer within 3 minutes
after shutdown. Wait for 3 minutes before restarting.
Resume the operation after resetting the circuit breaker
to ON. If the circuit breaker still trips to OFF, failure of
electrical insulation may have occurred. Remove the
power supply and contact one of our agents for further
instructions.
・
Poor ventilation in installation
location.
・
Ventilation grille is obstructed by
a wall or blocked with dust.
・
The dust filter is blocked
・
Improve ventilation by installing ducts etc.
・
Install so that front and back ventilation ports are far enough
from walls. Page 2-3
・
We recommend frequent cleaning of the ventilation grilles.
(Once a month as a guide)
・
Ambient temperature is too high
・
Reduce ambient temperature to within the specifications.
・
Compressed air flow rate is too
low or not flowing, or is too high
・
Use with flow rate of compressed air within the specifications.
(If the flow rate is too low or not flowing, the heater may overheat,
activating the thermostat.)
・
Adjust using the flushing valve.
Pages 3-1 and 3-2
・
Inlet air temperature is too high
・
Improve the ventilation system around air
compressor or make ambient temperature around air
compressor low to lower the temperature of
discharge from compressor.
During operation, the
light goes out and the
chiller stops.
・
The power supply voltage
changes largely.
・
Install a power supply transformer and review the power
supply to keep the voltage adequate value.
Allowable fluctuation of the power supply voltage is
+-/10% at max. of the rated voltage.
・
Poor ventilation in installation
location.
・
Ventilation grille is obstructed by
a wall or blocked with dust.
・
The dust filter is blocked with oil,
foreign matter, dust etc.
・
Improve ventilation by installing ducts etc.
・
Install so that front and back ventilation ports are at least 40cm
from walls. Page 2-3
・
We recommend frequent cleaning of the ventilation grilles.
(Once a month as a guide)
・
Clean or replace the dust filter.
・
Ambient temperature is too high
・
Reduce ambient temperature to within the specifications.
・
Compressed air flow rate is too
high.
・
Use with flow rate of compressed air within the specifications.
Evaporation
thermometer indicates
higher than green zone.
・
Inlet air temperature is too high
・
Improve the ventilation system around air
compressor or make ambient temperature around air
compressor low to lower the temperature of
discharge from compressor.
