fault
Possible cause
Rectification
Function
Power supply is faulty
– Check the power supply.
– If the power supply is OK, contact BOGE Service or send the
DL dryer to the manufacturer.
Water in compressed air
network
Faulty condensate drain
(blocked drain pipe,
minimum operating pressure
not reached)
Clean condensate drain with a neutral cleaning agent
DRL 6-2 DL dryer
switches off during
operation
DL dryer is being switched off
by the installed electrical
start-up and protective equip-
ment due to overload
– Rectify the cause of the fault.
– The DL dryer will switch back on automatically once the pro-
tective equipment has cooled down.
Note: the device may not switch back on immediately,
as the protective equipment needs a certain amount of time
to cool down to an acceptable operating temperature.
Condenser is dirty
Clean the condenser.
High pressure difference
on the compressed air
side
Features:
– Pressure difference on
the compressed air side
is increasing.
– Volume flow is decreas-
ing.
DL dryer is freezing
Switch off the device and continue to allow compressed air to flow.
After approx. After approx. 1/2 h, the pressure difference will return
to the normal value.
Switch the device back on. If the device freezes again, contact
BOGE Service.
