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 Excessive temevature rise in UPS repeated 3 times in 30 min.
Possible Causes: 1) Overload
2) Fan failure or dirty 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 for the return of electric.
A6 CHARGER FAULT Rectifier is not producing 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, please check loads.
A10 LINE FAILURE Line failure.
Possible Causes:
1) Maybe line out
2) There is a problem on the UPS input board. Please Check.
3) UPS input fuses blown.
A11 HIGH TEMPER Over temperature. (inverter or rectifier section)
Possible Causes: 1) Overload for inverter
2) Over temperature
3) Fan failure or dirty 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 blown. (not used at this power range)
A16 BYP INPUT BAD
During transfer to bypass,Voltage or frequency value of bypass source is out of
limits 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
A18 BATT.CAPA.LOW
If the battery charge is low this message indicates that charge period is not
completed. If mains failure occurs during this message battery operating time is
not valid.
UPS gives beep sound whitin 15 sec
