Temporary problem with voltage drop

Hello all..


I'm working on a C32 SXC generator with an EMCP 4.3 control unit. When I start the unit, the voltage is coming to 200V instead of 400V. I checked configuration settings, connections and all possible causes, everything is OK.

After some hours with attemps of turn on - shutdown the generator work properly with correct voltage, without making any actual repair and still ok for mor than a month

I still dont know what the issue and what is the cause.

I wait for any solutions or suggestions that may help me to get the answer.


Thank you everybody fo your helps.
