Correction
This can occur if the CP on the CPU is restarted or a board failure is
detected by the RP. Check if it concerns just one or more board(s). A
watchdog reset on the board could cause a board restart. System
supervision will invoke a system restart if major faults occur. If LED is
continuously ON check if the yellow and green LEDs flash, otherwise
the RP is not working.
This condition is normal for a start-up sequence indicating initialisation
or running self test. If this LED is ON during operation, this indicates
blocking of one or more individual(s). The proper action is to check the
wiring and if the connected equipment is operational (check it's alarm
indication).
This indicates normal system operation and at least one e.g. extension
(individual) is active on the board.
This indicates that the register function on the board is blocked e.g. on
BTU-D or VMU-HD.
This indicates normal system operation. This register function is active
on the board e.g. on BTU-D or VMU-HD.
