Setting
Fault relay
Energized / Normally Open
Yellow Fault LED Lit if a fault message is available
Red Alarm LED
Single blink if A1 condition is present. Double blink if A2 condi-
tion is present. If an alarm is configured as acknowledgeable
and the alarm is acknowledged, single/double blink changes
into continuously lit.
Alarm Hierarchy A2 overrides A1 on the LED. However, the A1 and A2 relays
operate independently. I.e. if A1 is acknowledgeable and A2 is
not, and the gas concentration is such that it triggers A1 and
A2: acknowledging will cause the A1 relay to release. However,
the red LED will still double blink as long as the A2 condition
continues to exist.
