Diagnostics
The actual status can be read on the outside of the
FCD products. Five LEDs signal the actual status of
the unit with the meaning described in the table.
Further detailed status information can be obtained
using a local control panel (LCP2 – see photo). This
can be connected on the outside (without opening the
enclosure) if the LCP2-plug shown on the drawing is
installed. The LCP2 is an easy-to -navigate user-friendly
interface used to access and adjust all parameters. It
displays parameters in six different languages.
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.
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.
