Alarm Configure
This menu option allows you to define whether alarms should trigger
based on a high alarm or a low alarm condition.
Whether Alarm 3 is set high or low applies only 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.
If you select Hydrocarbon Upset as the Sensor Config. option from the
Setup Key menu, Alarm 4 is fixed as both a high oxygen alarm and the
alarm that triggers during a hydrocarbon upset condition. In this case,
you will not be able to select Alarm 4 as a low oxygen alarm. Alarm 3,
however, can still be selected as a high or low oxygen alarm.
Configuring the alarms
1. Select
Alarm Configure
from the Alarm menu.
2. Define Alarm 3 and Alarm 4 as high or low alarms.
3. Press the
Cancel
Key to then exit this menu option.
