Operation and Maintenance

NEW EcoCooler

DSKE.191101.01.EN

Continuous product development may give rise to specification changes without notice.

6.2 Troubleshooting via symptoms

Symptom

Possible cause

Corrective action

Low cooling power - too

high temperature in the

cooled object

The power supply has been interrupted.

Check the control/safety switches and

fuses.

No air flow or too low air flow across eva-

porator.

Check that nothing is inhibiting the air

flow.

The control equipment is incorrectly pre-

set/defective

Adjust the settings or replace the

equipment.

Compressor is not ope-

rating

The power supply has been interrupted.

Check the control/safety switches and

fuses.

The compressor has tripped the high

pressure switch.

Check and reset, if needed.

Defective compressor

Check/replace

Frost on the evaporator

The expansion valve is incorrectly preset/

defective

Check/replace

Insufficient refrigerant volume

Search to detect leakage, seal the leak

and charge with refrigerant

Low supply air flow

Adjust the flow

Alarm reset

In the event of an alarm initiated by the frequency inverter or the high pressure

switch, the compressor stops and the sum alarm relay is energised. The alarm

is displayed in the control unit menus “Operating information, compressors” and

“Status: Alarm”.

In the event of an alarm, take corrective action to correct the fault, and then

press the “Alarm reset” button on the control unit for 3 seconds. If the high pres-

sure alarm trips repeatedly, an authorised refrigeration service company must be

called in.
