The digital alarm output indicates the alarm group that contains
the highest priority active alarm. This output is ON when no
alarms are active. The options for the action of this output
when an alarm in a group occurs are ON, Fast Blink, Slow
Blink, or OFF. These can be edited via the keypad/display.
The default values for the three groups of alarms are:
• Warnings - OFF
• Problems - Slow Blink
• Faults - Fast Blink
A user could eliminate any signal of a particular group of
alarms through this output by selecting ON for that alarm group
in the keypad/display.
