1. If supply on RSBS is removed before the recovery period (6 mins) has elapsed, when supply is restored, the remaining
delay will continue until the remaining recovery time (before supply removal) is over.
Alarms
The RSBS includes a number of diagnostics and protection features each of which is signalled through a flashing sequence
on the red LED.
Note: In case there is a fault in the internal power supply (PSU) of the RSBS, the green LED (and not the red LED) will start
flashing. In this condition, the relay contact will not change state.
Flashing sequence
Every alarm that the RSBS will trigger will be signalled via a specific flashing sequence on the red LED. The specific alarm
will flash with a period of 2 s ON, 2 s OFF.
Flashing sequence during recovery from alarm
When the alarm can self-recover, the flashing sequence of the red LED will be interleaved with a 6 s ON-OFF-ON flashing
sequence and then the flashing sequence will repeat (see diagram below).
