12.6 Gas settings

Gas settings are not used in Polytron 8900 UGLD.
13 Factory default settings
13.1 Fixed settings for relays, LED and
alarm
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 condition 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 inde-
pendently. I.e. if A1 is acknowledgeable
and A2 is not, and the gas concentra-
tion 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 con-
dition continues to exist.
