Operation and Maintenance

ThermoCooler HP

DSTCH.191101.01.EN

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

6.3 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.

Separate supply not connected

Connect supply

None or too low air flow across evapora-

tor

Check that nothing inhibits 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

Incorrect phase sequence (compressor 2) Switch two of the incoming phases

Compressor has opened a safety circuit

Check and reset, if needed

Defective compressor

Check/replace

Frost on the evaporator

(heating application)

Expansion valve is defective

Check/replace

Insufficient refrigerant volume

Look for leakage, seal the leak and top

up with refrigerant

Low return air flow

Adjust the flow

6.4 Alarm reset

In the event of an alarm initiated by the frequency inverter or the safety circuit,

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 at least 3 seconds. If the

safety circuit alarm trips repeatedly, an authorised refrigeration service company

must be called in.
