Yellow Fault LED
Lit if a Fault message is available, see
Section 5.3 on Page 22.
Red Alarm LED
Single blink if A1 condition is present.
Double blink if A2 condition is present.
If an alarm is configured acknowledge-
able and the alarm is acknowledged,
single/double blink changes into
continuous lit.
Alarm Hierarchy
A2 overrides A1 on the LED. However,
the
A1 and A2 relays operate
independently. I.e. if A1 is acknow-
ledgeable, 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.
