Service And Maintenance; Supervision And Diagnostic Codes - JRC JLN-900 Installation And Instruction Manual

8 Service and maintenance

Two red 7-segment LED digits on the Sig. Distributor PCB are used to display status. At
normal operation the LED digits displays LED code:
A service web interface is also available at the Sig. Distributor IP-address, see menu S18
and S19.

8.1 Supervision and diagnostic codes

The Sig. Distributor supervises functions according to the table below. Diagnostic codes 400 –
499 are reserved for the Sig. Distributor. Active diagnostics are presented in Menu A,
accessible both from the Speed Log Master Display and the Sig. Distributor Web interface. The
last hundred diagnostics are saved in a history list only accessible from the Web interface.
The LED code (the two last digits of the diagnostic code) will be displayed on the red 2 x LED
digits on the CPU-PCB. If more than one diagnostic is active, only the highest LED code
(highest priority) will be displayed. All active diagnostic codes are listed in Menu A.
Note! $SDALR messages from Echo Sounder Display are not supervised.
