UPS output voltage is out of tolerance at 3 times in 30 min.
Internal failure. Call service.
Batteries empty at last of line out. Wait to return of electric.
Rectifier is not to produce DC bus voltage.
Batteries are low.
1) UPS wrought long time when line out
2) Charger system failure
Inverter output voltage is over than max. tolerance voltage value.
Inverter is stopped.
1) Inverter failure
UPS loaded over than max. %100 load level.
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.
Line failure.
1) Maybe line out
2) There is a problem on the UPS ınput board. Please Check.
3) UPS input fuses blowned.
Over temperature. (inverter or rectifier section)
1) Overload for inverter
2) Over temperature
3) Fan failure or durty air inlets
4) Bad UPS settling. There is not vantilation area.
Inverter output system failure.
1) Overload.
2) Short circuit.
3) UPS is out of order. Call service.
Inverter output voltage is under than min. tolerance voltage value.
Inverter is stopped.
Battery voltage is over than max. tolerance.
Fuse blowned. (not used at this power range)
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.
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
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
Battery test aborted. And batteries are not OKAY
UPS gives beep sound whitin 15 sec
You can clear this message by pressing 3 seconds to ENTER key
2) Battery cells damaged
3) PURE battery connection
Boost charge is active for 10 hours. At the end of this time UPS stops the boost
charge.
UPS gives beep sound whitin 15 sec
Phase sequence is changed on the UPS input. Please change.
In parallel system, the operation mode of 1 UPS is differenf from the other
Parallel controller board failure
Parallel controller board failure
Parallel controller board failure
