The current operating state of the circuit packs is displayed by means
of the following 3 diagnostic LEDs:
•
ACTIVE
ON in case of active status. In standby mode the LED is dark.
•
FAULT
ON or FLASHING in case of hardware failure or wrong
detection in the system.
Check that on each circuit pack only the ACTIVE LED is lit up. This

is the case if there are no alarms present on the circuit packs.
Otherwise, the FAULT LED is lit up or flashing. The test should be
carried out for each installed NE.
Important! The LEDs of the protection cards are off as long as they
are in the standby mode.
