Ups inverter doesn't start

[eks1531]

Gutor ups PEW 1010-220/230-EN

inverter doesn't start in auto mode. When try to start the transformer give very loud humming sound and go to standby. To confirm what's  the problem i swap all the card from other healthy ups.  But still the same. Checked IGBT found good. Few alarms :-

34: Inverter voltage error

43: Output ints out of tolerances 

24: Current limiter active

44: Output is out of tolerances 

51: Synchronization error

Please give me some lead to troubleshoot. I'm blank. Thanks

Hi @eks1531 , Gutor is not anymore part of Schneider Electric since August 2023. We are advising you to contact Gutor directly here: https://www.gutor.com/contact-us/

Agree to contacting Gutor as well. If you have the inverter manual it should have a list of the error and alarm descriptions and some troubleshooting steps.
I am retired Power Generation technician and we had at our power station Gutor inverters.
