Yellow Fault LED Lights when a fault is present
(see chapter 9 on page 27).
Red Alarm LED Gives single flashes when an A1 alarm
is present.
Gives double flashes when an A2 alarm
is present.
If an alarm is configured as
acknowledgeable and the alarm is
acknowledged, the LED lights.
Alarm hierarchy: A2 has a higher priority
for the LED than A1. However, the A1 and
A2 relays operate independently of one
another, i.e. if A1 is acknowledgeable and
A2 is not and the gas concentration is
so high that A1 and A2 are triggered,
an acknowledgement results in the
A1 relay dropping out. However the red
LED continues to give double flashes as
long as the A2 condition exists.
