Check your incoming power. Make sure that your internal transformers are set to the same as your 3 phase. You cannot have no more that 3 % difference between leggs R-S-T and no more than 4% difference from your incoming to your xformers taps inside the generator.
OK.So if your 3 phase is 400 vac, make sure that the taps on theinternal transformers are also set for 400vac. I believe you have 4 xformers on that 100 series machine.
