Alarms configuration

For the standard alarms, you must configure the following features by using the display or communication:

• Pickup setpoint

• Trigger delay (Pickup/Dropout delay)

• Dropout setpoint (Deviation percentage from pickup setpoint)

Among the standard alarms, dropout setpoint and trigger delay are common features of all the alarms. Pickup setpoint is identical for each alarm.

For more information on how the meter handles the setpoint-driven alarms, refer to the following figure:

		A	The value of the variable monitored by the alarm.
		B	Trigger delay (Pickup or Dropout delay) NOTE: The time delay is satisfied only if during the delay, the actual value does not fall between the pickup setpoint and dropout setpoint.
		C	An alarm is active. The meter records the date, time, and value when the pickup setpoint and time delay are satisfied. The meter performs any tasks assigned to the event such as: switching on a digital output, and flashing the backlight or the alarm symbol.
		D	Alarm period
		E	An alarm is inactive when both the dropout setpoint and the time delay are satisfied. The meter performs any tasks assigned to the event such as switching off a digital output, and ceasing to flash the backlight and the alarm symbol.

For the Over Energy alarm, you also need to configure the method, which refers to the energy accumulation and detection period.

The 3 options are:

• Day method: the energy accumulation starts at 8:00 A.M. every day and clears up at 8:00 A.M. the next day.

• Week method: the energy accumulation starts at 8:00 A.M. every Sunday and clears up at 8:00 A.M. the next Sunday.

• Month method: the energy accumulation starts at 8:00 A.M. on the first day of the month and clears up at 8:00 A.M. on the first day of the next month.

When the accumulated energy pickup setpoint and time delay are satisfied, the alarm is active. When the accumulated energy dropout setpoint and time delay are satisfied, the alarm is inactive.
