Faults

If case of faults, the display will show a fault code.
If the unit is not in refrigeration operation and not in
defrosting operation, the fault report relay is not in
operation. A fault report is possible using the
potential-free contact.

10.1 Fault codes

See section on the regulator 7.3 Fault reports

10.2 Emergency operation

BIn case of stoppage or fault in the regulator, the
refrigeration unit can continue to operate in emergency
mode.
The emergency switch is on the left side of the electronics
box. It can be activated without removing the covering by
means of the air holes on the left plate, using a long
screwdriver.
In turning this flip switch on, the exit relay for the
compressor and the fans is directly activated. The unit
begins continuous operation. The function of the
pressostat as a safety device is retained.
The fault code „F10" appears in the display in case
emergency operation is switched on.
Emergency operation must be monitored, as the coldroom
temperature is not regulated and the automatic defrosting
system does not work. The coldroom temperature must be
regulated manually by interruption of the power supply at
intervals.
