I setting over/under voltage to digital output of PowerLogic PM5300 series meter (EX. PM5350), but signal pickup is good but signal dropout not operation, so I do not control output of meter.
Thanks!

Hi @huy_nguyen1706,
The power meter PM5350 has two relay outputs, DO1 and DO2. The relay output can be configured as an alarm by selecting 'alarm' from the available list as a parameter.
The relay output turns on when an alarm is activated and turns off when it is deactivated.
Please refer to the diagram below to understand how the power meter handles setpoint-driven values.
EV1—The power meter records the date and time that the pickup setpoint and time delay were satisfied, and the maximum value reached (Max1) during the pickup delay period ('T). Also, the power meter performs any tasks assigned to the event such as the operation of a relay output.
EV2—The power meter records the date and time that the dropout setpoint and time delay were satisfied, and the maximum value reached (Max2) during the alarm period.
Are you configuring a dropout delay? If so, the value must be below the dropout setpoint for the specified time; otherwise, the alarm will remain active.
Additionally, ensure that you are configuring the correct VLL or VLN values based on your system and meter's measurements.
Best Regards,
JD
