Overview of Alarm Functions
ALARM NUMBER

the start of a verication (Select Function). All other alarms are set to activate based on
only a single condition; for Alarm 4 this condition is levels of oxygen, for Alarms 5 and
6 this condition is high combustible levels (% or PPM scale), for Alarms 7 and 8 this
condition is high methane.

Alarm Set Points
For oxygen alarms, these values depend on the Alarm
Congure menu option for whether they are high or low
alarms.
Exception Log
The exception log provides a history of events, such as
system or error messages, alarm conditions, and the
start of calibrations or verications.
Alarms 1 and 2 are reserved for Watchdog and Service alarms and are not software-
selectable. They always de-energize on alarm (FAIL SAFE).
