METER ALARMS
Set up alarm characteristics for each metering channel on the
Meter Alarms
tab.
DELAYED ALARM REPORTING
Any metering channel can be configured to delay alarm reporting for a preconfigured duration, as specified under
the Alarm Delay heading. When a delay is configured, the channel must be continuously out of tolerance for the
duration of the delay before the alarm will be logged or reported.
REARM DELAY
The ARC Plus has a built-in mechanism to reduce multiple alarm reports due to a single alarm event. An out-of-
tolerance metering channel that returns to tolerance must remain within normal limits for a period of time before
a new alarm is issued on that channel. Use the Rearm Delay column to specify this period.
For example, a channel configured to cause a high temperature alarm immediately upon reaching 90 degrees will
report the alarm as soon as the temperature reads 90. However, if the temperature decreases to 89.9 and returns
to 90 after less than the rearm period, a second alarm is not issued.
