Setup

Low Process Alarm Output Number

Use this menu to assign the digital output that activates when the loop is
in low process alarm.

Selectable values: 0-30.

Alarm Deadband

Use this menu to set an alarm deadband. This deadband value applies to
the high process, low process, high deviation, and low deviation alarms
for the loop you are editing. Use the alarm deadband to avoid repeated
alarms, as the PV cycles slightly around an alarm value.

Selectable values: 0-255.

Alarm Delay

Use this menu to set a loop alarm delay. This delay is set seperately for
each loop. It delays failed sensor and process alarms until the alarm
condition has been continuously present for longer than the alarm delay
time you set.

Selectable values: 0-255 seconds.
