Alarm Congure
Define whether alarms should trigger based on a high alarm or a low
alarm condition. If you have the combustibles or methane options, Alarms
5 through 8 always act as high alarms. So, for example, Alarm 5 could be a
high combustibles alarm, and Alarm 6 could be a high/high combustibles
alarm.
Whether Alarm 3 is set high or low only applies if it is set to track
oxygen levels (% O
2
). If Alarm 3 is set to trigger at the start of a cali-
bration or verification, this option does not apply.
Conguring the alarms
1. From the Alarm menu, select Alarm Configure.
2. Define Alarm 3 and Alarm 4 as high or low alarms.
3. Press Cancel to exit this menu option.
Relay Congure
All Series 2000 control unit relays are Form A, normally open contacts.
You can use the software to set whether these alarms should close on
an alarm condition (energize on alarm) or open on an alarm condition
(de-energize on alarm). This menu option applies to all alarms except for
the service and watchdog alarms, which are always set to de-energize on
alarm (fail-safe).
