6. FAULTS AND TROUBLESHOOTING
6.1 DEW POINT TOO HIGH
POSSIBLE CAUSE SOLUTION
Operating pressure too low, air flow
volume too high Increase operating pressure, reduce air flow
capacity
Air inlet temperature too high
Reduce temperature or connect an air
cooler upstream
Differential pressure at the prefilter is
too high
Replace filter element
Condensate drain is not functioning
Check operation of the condensate drain
and replace if necessary
Desiccant is soiled or has disintegrated
Replace the prefilter element and the
desiccant.
Dispose of the old desiccant.
Check the afterfilter
Danger!

Wear protective equipment when handling desiccant

Understand the danger by studying the Material Safety Data Sheet
provided in Appendix A.
Volume of regeneration gas too low
Check regeneration orifice for soiling, clean
if necessary; check operation of muffler and
depressurization
valve, replace if
necessary.
6.2 VESSELS DO NOT SWITCH OVER
POSSIBLE CAUSE SOLUTION
The inlet valve V1 (V2) does not open
Check the electrical functioning of the
solenoids and replace either the solenoid or
the complete valve assembly
The printed circuit board (PCB) does
not function Check functioning of the PCB and the fuse
in the control cabinet
The vessel is not pressurized
Check whether the depressurization valves
are dirty and replace these if necessary;
Check the electrical functioning of the
solenoids and replace either the solenoid or
the complete valve assembly
The regeneration orifice is obstructed Clean or replace the regeneration orifice
