9. Malfunctions,
troubleshooting
Remark!
The component specified in parentheses (e.g. A103)
refer to the R&I schematic diagram.
Please see also section 13. „Dimensional drawing“.
9.1 Malfunctions without fault messages
Water in the compressed-air system
Possible cause:
a)
Condensate residues which formed prior to starting up the
dryer are in the compressed-air system.
b)
Bypass open.
c)
Compressed-air inlet and outlet connections reversed.
d)
Condensate not separated.
Remedy:
a)
Blow out compressed-air system with dry air until no more
moisture is evaporated out. Open collection point at most
remote position, if possible
b)
Close bypass.
c)
Check the compressed-air connections by reference to the
dimensional drawing (see section 13).
d)
Check the solenoid valve (H115) and the timing device (mounted
on the solenoid valve) for correct functioning. Condensate
must be discharged when the solenoid valve is switched on
High pressure loss through
the refrigerated compressed-air dryer
Possible cause:
a)
Air system frozen.
b)
Refrigerated compressed air dryer overload (air flow).
Remedy:
a)
Set switch „0-I“ to position „0“ (OFF) until the air system is
defrosted. If the system freeze again after restarting, have
the setting of the heating gas controller (P212) checked by
authorised specialist personnel and adjust if necessary.
b)
Check design specifications (see section 10).
