4.2 Alarms and Troubleshooting
Totally 64 alarms and status messages (might be extended, please consult us) are used in UPS,
which helps the user. Messages are coded for easy dialog with service organization, all messages
contains numbers A1-A2-A3….An. Messages and events in UPS are recorded to a log file with
event time and date
ALARM DESCRIPTION
A1 BYPASS FAILURE Bypass system failure
Possible Causes: 1) Maybe bypass parts are defective call service
A2 INVERTER FAILURE Inverter digital start system is failed
Possible Causes: Internal failure. Call service.
A3 3 OVERTEMP Overload in UPS repeated at 3 times in 30 min.
Possible Causes: 1) Overload
2) Fan failure or durty air inlets,outlets
3) Bad UPS settling
A4 OUT FAILURE
UPS output voltage is out of tolerance at 3 times in 30 min.
Internal failure. Call service.
A5 BATT AUT END Batteries empty at last of line out. Wait to return of electric.
A6 CHARGER FAULT Rectifier is not to produce DC bus voltage.
A7 BATTERY LOW Batteries are low.
Possible Causes:
1) UPS wrought long time when line out
2) Charger system failure
A8 OUTPUT HIGH
Inverter output voltage is over than max. tolerance voltage value.
Inverter is stopped.
Possible Causes: 1) Inverter failure
A9 OVERLOAD UPS loaded over than max. %100 load level.
Possible Causes:
Load on the UPS output is over than max. Load capacity. This state is maybe
continous or short time. When this alarm is continous to check loads.
A10 LINE FAILURE Line failure.
Possible Causes: 1) Maybe line out
2) There is a problem on the UPS ı nput board. Please Check.
3) UPS input fuses are blowned.
A11 HIGH TEMPER Over temperature. (inverter or rectifier section)
Possible Causes: 1) Overload for inverter
2) Over temperature
3) Fan failure or durty air inlets
4) Bad UPS settling. There is not vantilation area.
A12 IGBT FAILURE Inverter output system failure.
Possible Causes: 1) Overload.
2) Short circuit.
3) UPS is out of order. Call service.
A13 OUTPUT LOW
Inverter output voltage is under than min. tolerance voltage value.
Inverter is stopped.
A14 BATTERY HIGH Battery voltage is over than max. tolerance.
A15 FUSE FAILURE Fuse blowned. (not used at this power range)
A16 BYP INPUT BAD
During transfer to bypass, Voltage or frequency value of bypass source is
incorrect and the UPS turn off the load power.
During normal (inverter) operation some times you can see this message.
During bypass if the bypass protection option is on and if the bypass source is
tolerant out UPS switch off the static bypass for load protection.
A17 BATT CB OPEN
Battery circuit breaker is off, batteries are not connected to UPS
At start up if the mains is okay you can start operation but this message is
active
At start up during line failure UPS waits for turn on battery CB and then it starts
