Set Alarm Delay:
Once the values for ALARM 1 and ALARM 2 have been entered, the user may elect to delay the activation of the local alarms
and relay contacts for up to 99 minutes. This feature allows users to distinguish between transient occurrences and true upset
conditions. This feature can be particularly useful on remote applications without affecting the 4-20mA signal output.
