Internal system error
Different units in a filter system have different settings (e.g. 3-
wire and 4-wire setting) or are connected in a different way.
gives an overview of the faults that can be reported by the µcontroller.

· For multi-unit filters, this data can be obtained for each individual unit.
· Internal system errors are most likely due to faulty hardware and thus the only
solution may be to exchange the controller cards.
· If the message 'IGBT check cooling' appears, this implies that the system is
stopped due to an over temperature problem.
In that case, check the cooling of the system (fans, filters) and of the switchgear
room (air conditioning system etc.)
