FAULT CODES
COMPRESSOR ELECTRICAL PROTECTION
Fault Code: 1n4
Description
During start up or operation of a compressor m:
• The thermal magnetic trip breaker or the compressor internal protection from circuit n is tripped
• The phase rotation protection has detected an incorrect connection (standard on screw compressor and
available as a special request on other units)
• The discharge line thermostat is tripped out (screw compressors only)
Action
$ Immediate shut down of compressors m from circuit n.
$ Fault signal shown on the display.
$ The remote fault signal is delayed by 6 minutes.
Reset
If the fault signal comes from the internal compressor protection, it can be automatically reset. In this case,
Climatic 50 will restart the concerned circuits 30 minutes after shutdown.
After three automatic reset of the compressor fault signal, the circuit n can only be restarted by a manual
reset of the fault signal.
Important
: For manual reset of ZR 380 internal protection cut off; if the problem comes from a high
discharge temperature, wait for 30 mn prior to any manual reset to allow the scroll temperature to decrease
sufficiently. If the temperature is still too high, the compressor will trip again just after starting.
Notes:
Fault counter is cleared and reset every day at 10 am, as long as the maximum number of faults has not
been reached.
The fault signal is reset automatically with each powering of the unit
Possible causes Solving the problem
Wrong wiring or tightening of the connections. Control all connections
Wrong setting on the circuit breaker
Set circuit breaker according with compressor
normal running current
