Hello, our MGE GALAXY 3000 20kva, front panel display is frosen. UPS still operates but not able to use any buttons to see ups status. Also alarm states "internal communication fault". Would appreciate help for solution to solve problem. Thank you

If you cannot do a reset of the internal fuse system and get it operational, then check the internal battery for continuity. If they all fail, then the AC/DC transformer has blowen.

what alarms are shown on the display??
measure voltage of batteries, you have to read 13 to 13.5 volts.
what is the status of QF1 switch and Rotary Sw??

Is the UPS in Bypass? Is the Inverter running? What alarms other than that code are on? Have you shut the unit down. Its best to call MGE, that unit requires to have software to work on it. Even though you find the problem, and replace the board, the Board needs to be program to that unit. YUP! This way MGE always makes money on the UPS's no matter where and no matter how old the UPS is. They lock you out. Which is unfair for the customer. The customer has no choice but to call the dealer to fix it. Trust me.. Then again when a customer buys a product, isn't it his for life? Why can't he fix his ups or hire whoever he wants besides the Manufacture? Wrong, NOT WITH MGE Products. I guess it's Job Security for MGE. That one positive thing.

Dear Yared,
The alarm is pretty clear about what is going on. It's a syncing issue between the inverter and your bypass supply.

What you can try is to go to the 'Command Screen' of the UPS and select Resynchronize AC BP.

Best regards,


Ron

No you don't have to reconfigure the UPS after battery replacement. However you may have to reset the battery Timer. There are 4 possible ways.
1. Press and hold the fault reset button for 3-5 seconds
2. Press and hold the fault reset and security key simultaneously for 3-5 seconds
3. Press an dhold the fault and alarm silence buttons simultaneously for 3-5 seconds
4. Cycle the logic Power. This means to remove power from the main processor.
5. Call MGE. They have the software to reset the battery replacement alarm

Unfortunately the reset is only possible with MGE software (Softunor).
