Available standard alarms
Your meter has a set of standard alarms.
NOTE: Some alarms do not apply to all power system configurations.
For example, line-to-neutral voltage alarms cannot be enabled on 3-phase
delta systems. Some alarms use the system type and the VT or CT ratio
to determine the maximum allowed setpoint.

| *The Over Voltage THD alarm is only applicable for L-L voltage. | ||||
| **Available in specific meter models. Refer to Features differentiation matrix for PM5500 / PM5600 / PM5700 series for the availability. | ||||
| NOTE: For toroid used, the pick-up and drop-out values for over current AL1 I5/I6 and over current AL2 I5/I6 should be set within the range of residual current measurement meeting specified accuracy as mentioned in table Toroid turns setting example. | ||||
RCM alarm application
You can choose:
-
Any one alarm (AL1 or AL2) for notification and one for operating digital output.
OR
-
Both AL1 and AL2 alarms for notification.
OR
-
Both AL1 and AL2 alarms for operating digital output.
Typical dual alarm application for I5 or I6:
NOTE: It may take up to 30 s for RCM values to populate after meter reset
or power-up.
