5. Troubleshooting
5 - 2
Problem
Probable causes
Action
・
The valve in the inlet/ outlet
piping is not fully opened.
・
Be sure to use the dryer with the inlet/ outlet piping valve fully
opened.
・
The air filter in the compressed
air piping is blocked.
・
Replace the element of the air filter on the inlet side or built-in to
this product. Page 4-4
Large pressure drop.
・
Compressed air flow rate is too
high.
・
Use with flow rate of compressed air within the specifications.
・
The bypass valve is open.
・
Be sure to use the dryer with the bypass valve fully closed.
・
Drainage fluid is not discharged
from the auto drain.
・
Check that the drain tube is not trapped or bent.
・
Check the auto drain.
・
Check the auto drain strainer.

Moisture is generated
downstream of the
compressed air line.
・
The piping converges with piping
from a separate air line that
does not have an air dryer.
・
Install an air dryer in the line that does not have one.
・
Separate the two lines so they do not converge.
・
The set pressure is too low.
・
Adjust the pressure with the pressure adjustment handle.
Page 3-1
Compressed air does
not flow.
・
The inlet/ outlet valve is closed.
・
Open the inlet/ outlet valve.
The air pressure cannot
be set.
・
The pressure adjustment handle
is locked.
・
Release the lock of the pressure adjustment handle.

・
Air flow rate is too low or not
flowing
・
Use with flow rate of compressed air within the specifications.
・
Set temperature is too low.
・
Set the temperature within the setting range.
・
Compressed air flow rate is too
high.
・
Use with flow rate of compressed air within the specifications.
The outlet air
temperature is higher
than the set temperature
・
Inlet air temperature is too high.
・
Reduce the inlet air temperature to within the specifications by
reducing the ambient temperature or installing an after cooler.
The outlet air
temperature is lower
than the set temperature
・
Set temperature is too high.
・
The air outlet piping is reverse to
the air Inlet piping.
・
Temperature fuse is activated.
・
Set the temperature within the setting range.
・
Perform proper connection of piping.
Page 1-1
The outlet air
temperature fluctuates.
・
P.I.D setting value is not proper.
・
There is voltage fluctuation.
・
Set P.I.D value manually or by auto-tuning. Page 3-3
・
Connect to a power supply that can supply a steady voltage.
The temperature
controller buttons do not
work.
・
The temperature controller key
lock is on.
・
Release the key lock. Page 3-4
The temperature
controller display is:
・
The contact of the temperature
sensor terminal is bad, or wiring
has been disconnected.
