-427
Pressure sensor detects excessive
condensation pressure.
• Check ambient temperature and
reduce if necessary.
• Check condenser for soiling and clean
as necessary.
• Switch off the unit at the mains switch,
wait 4 seconds and then switch the
unit on again.
• For water-cooled units: Check cooling
water temperature and supply.
• If the fault has not been remedied,
contact Technical Service.
-431 The maximum permissible current
consumption at the compressor has
been exceeded.
• Check mains voltage for nominal
voltage.
• If the fault has not been remedied,
contact Technical Service.
-1427 Pressure sensor detects excessive
compensation pressure.
• Check ambient temperature and
reduce if necessary.
• Check condenser for soiling and clean
as necessary.
• Switch off the unit at the mains switch,
wait 4 seconds and then switch the
unit on again.
• For water-cooled units: Check cooling
water temperature and supply.
• If the fault has not been remedied,
contact Technical Service.
-1431 The minimum permissible current
consumption at the compressor has
been fallen short of.
• Check mains voltage for nominal
voltage. The specified voltage
tolerance of the unit must not be
exceeded.
• Check the mains cable of the
refrigeration unit for damage and
replace if necessary.
• Check ambient temperature and
reduce if necessary.
• Check CAN bus cable for damage and
replace as necessary.
• If the fault has not been remedied,
contact Technical Service.
