Overvoltage Operation Diagram
(Output Relay Drive Method: Normally Closed)
DIP switch setting: SW3 ON.
Note:
The power ON lock prevents unnecessary alarms from being
generated during the instable period when the power is first
turned on. There is no relay output during timer operation.

Undervoltage Operation Diagram
(Output Relay Drive Method: Normally Open)
DIP switch setting: SW3 OFF.
Note:
The power ON lock prevents unnecessary alarms from being
generated during the instable period when the power is first
turned on. There is no relay output during timer operation.
Note:
There is no polarity when a DC current input is used.
