The FCD 300 holds a log with valuable information on failure. Information on the most recent 10 faults is stored and indexed in three different parameters
to help diagnosis.
Illustration 5.1: LCP2-plug
Parameter 616
stores the time of the fault as measured by the internal
clock.
Paramet er 617
holds a fault code telling the type of fault detected.
Parameter 618
stores a measurement relevant for the case. Typically
the intermediate circuit voltage or output current measured immediately
before failure.
