ALARM 

DESCRIPTION 

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 ınput board. Please Check. 

 

3) UPS input fuses 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 

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 

A19   BATT  FAULT

 

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 

Possible Causes: 

1) Rectifier fault 

 

2) Battery cells damaged 

 

3) PURE battery connection 

A20 BOOST CHARGE 

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 

A21 ROTATE PHASE 

Phase sequence is changed on the UPS input.  Please change. 

A23 MODE FAILURE 

In parallel system, the operation mode of 1 UPS is differenf from the other 

A24   P.FAILURE 17

 

Parallel controller board failure 

A25   P.FAILURE 18

 

Parallel controller board failure 

A26   P.FAILURE 19 

Parallel controller board failure 

A27   P.FAILURE 20

 

Parallel controller board failure
