Generator SR4B doesn’t develop voltage!!

Hi everyone
We have a SR4B generator which has a DVR with CAT P/N 155-3836. The motor runs properly and speed reaches its normal level but the generator doesn’t produce voltage and reaches to only 10-20 V and after couple of seconds the fault code 0801 appears in DVR screen. Permanent magnet generates about 80V in three phase. The excitation voltage is only about 1.4V.
Please help. Thanks.
