WD2759 Typical Hookup
WD2759 Operation
WD2759 AC voltage sensing relays provide voltage monitoring and protection
in AC systems from 50 to 400 Hz. Sensing voltages, number of phases, over
and undervoltage setpoint, and time delays are user configured. WD2759
voltage relays operate when the externally adjustable trip point is reached. An
external time delay control is provided with an adjustment of .5 to 10 seconds.
This time delay may be used to prevent false tripping when there are slight
variations in the voltage supply.
energizes when the input signal exceeds the trip point. On undervoltage (UV)
the output relay de-energizes when the input signal goes below the trip point.
A green LED indicates power to the relay. Red LED lights indicate the state
of the undervoltage and overvoltage trips.

WD2759 Calibration
The calibration marks on the faceplate have a maximum error of 10% and
are provided only as guides. Proper calibration requires using an accurate
voltmeter in parallel with the input signal. Use the following procedure to
calibrate your relay.
OVER VOLTAGE
1. Remove cover.
2. Adjust the TRIP SET control fully clockwise (CW) and the TIME DELAY
3. Apply the desired trip voltage to the relay.
4. Slowly adjust the TRIP SET control CCW until the relay trips.
5. Remove the applied voltage (do not change the voltage level) and set
6. Apply the trip voltage to the relay and measure the time to trip.
7. Adjust the TIME DELAY and repeat steps 4 and 5 until you have the
UNDER VOLTAGE
1. Remove cover.
2. Adjust the TRIP SET control fully CCW and the TIME DELAY control fully
3. Decrease the applied sensing voltage from the nominal value until the
4. Slowly adjust the TRIP SET control CW until the relay trips.
5. Set the TIME DELAY control to the desired time delay and apply
6. Step down the applied voltage from nominal to a level jest below the
7. Adjust the TIME DELAY and repeat steps 4 and 5 until the desired time
