Code Description Note Type
AL094 EVD - LOP 2 alarm 2
AL095 EVD - MOP 2 alarm 2
AL096 EVD - Low overheating 2 2
AL097 EVD - Low suction temperature 2 2
AL100 Inverter – envelop init error The compressor is working out of envelope 3
AL101 Inverter – fault 3
AL102 Inverter – overcurrent 3
AL103 Inverter - over voltage 3
AL104 Inverter – over temperature
 inverter temperature too high
 check the liquid valve and/or refrigerant load. The valve activates
when the oil exceeds 100°C and deactivates when it goes below
95°C
3
AL105 Inverter – under voltage 3
AL106 Inverter – power supply fault  failure of a phase or imbalance between phases 3
AL107 Inverter – hardware fault 3
AL108 Inverter – temperature sensor fault
 inverter temperature sensor fault. Check the oil sensor and motor
sensor
3
AL109 Inverter – hardware conguration error  incorrect hardware conguration 3
AL110 Inverter – conguration data error  incorrect software conguration 3
AL111 Inverter – conguration parameter error  incorrect inverter parameters 3
AL112 Inverter – motor thermal overload  motor winding temperature above limits 3
AL113 Inverter – motor overload 3
AL115 Inverter – motor phase failed 3
AL116 Inverter – high oil temperature
 high oil temperature (check oil heater)
 warning if greater than 115°C
 fault if greater than 120°C
 reset alarm if less than 105°C
3
AL117 Inverter – low oil temperature 3
AL118 Inverter - Compressor Short Cycling
 compressor starting is requested before the minimum time
between two starts has passed. This occurs only at the Warning level
3
AL119 Inverter – envelope error The compressor is working out of envelope 3
AL120 Inverter – serial control timeout  power request from card pCO5+ to inverter timeout 3
AL121 Inverter – communication error 3
AL122 Inverter – datalog error 3
AL123 Inverter – pressure sensor fault 3
The alarms read by the compressor inverter card can have three levels, as indicated in the example window:
Inverter
AL: XXX U:01
(Warning/Critical/Fault)
ALARM NAME
— Warning: pre-alarm condition
— Critical: becomes Fault after 30’’
— Fault: compressor OFF manual reset alarm
