The proposed investigation route is as follows:

  • trace the problem, check all connections and cables for tightness
  • traced low insulation
  • from the experience, one of the probable causes could be a proportional valve (4/2 way solenoid valve) of a HSU - Pump. Disconnect it and the low insulation alarm should disappear.

The proportional valve may leak and have oil accumulated it a protection cover. If this is the case, it should be replaced at first opportunity.
