Setup

Alarm Delay

Use this menu to set a loop alarm delay. There are two types of alarm
delay: the start-up alarm delay and loop alarm delay. Start-up alarm
delay (which you can set in the Set up Global Parameters main menu)
delays process alarms (but not failed sensor alarms) for all loops for a
specified time after the controller powers up.

The loop alarm delay, in contrast, is set separately 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. (Failed
sensor alarms are not subject to the start-up alarm delay, but they are
affected by the loop's alarm delay during the start-up alarm delay
period.)

Selectable range: 0-255 seconds.
