Diagnostics
The actual status can be read on the outside of the
FCD products. Fi v e 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.
