4.1 Service
4.1.1 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.

before failure.
