10.2.2 Functions
General functionality
Depending on the setting, the 3UG4631 / 3UG4632 voltage monitoring relays are powered with
a rated control supply voltage of 24 V AC/DC or 24 to 240 AC/DC and monitor an AC voltage or
DC voltage at terminals IN and M of the device for overshoot (U▲) or undershoot (U▼) or
in range monitoring (U▲ and U▼).
The 3UG4631 / 32 voltage monitoring relays have a display and are parameterized with three
keys.
