Setup

NOTE

All digital outputs are "OR'ed" together (combined).
Therefore you can assign more than one alarm to the
same output number, and that output will be On if any
of those alarms is On.

Low Process Alarm Setpoint

Use this menu to set a low process alarm setpoint. (The low process
alarm activates when the process variable goes below the low process
alarm setpoint. It deactivates when the process variable goes above the
low process alarm setpoint plus the deadband.)

Selectable range: Any value within the input sensor’s range.

Low Process Alarm Type

Use this menu to turn off the low process alarm or set it to the Alarm or
Control function.

Selectable values: Alarm, Control, Off.

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: Any output number between 1 and 34, as long as it
isn’t used for control or the SDAC clock. You may also select NONE.
