Locator Function
A Undervoltage Inhibit Control. Relay operation is inhibited when the sensed voltage
decreases below the setting of this multi-turn potentiometer. The Undervoltage Inhibit
Control has a setting range of 40 to 120 Vac. The BE1-81O/U is delivered with the
control set at 80 Vac.
B Undervoltage Inhibit Indicator. This light emitting diode (LED) lights when the sensed
voltage decreases below the setting of the Undervoltage Inhibit Control. Relay
operation is inhibited when this LED is on.
C Over/Under Selector Switch. A two-position toggle switch configures the corresponding
frequency setting (locator D) as an overfrequency (O) or underfrequency (U) setpoint.
One selector switch is provided for each frequency setpoint of the relay.
