(pins numbered clockwise from keyway)

Note 1 – As voltage increases, the

relay will pick-up at its selected

point and remain energized while

voltage is maintained at that level or

higher.

Note 2 – As voltage decreases, af-

ter pick-up, the relay will drop-out at

its selected point.

Note 3 – Minimum hysterisis, the

voltage differential between pick-up

and drop-out, is typically 2% of

pick-up.

Sensing Modes

The CS can be used as an over or undervoltage sensor, depending upon

whether the load is connected to the normally closed (NC) or normally open

(NO) contacts of the sensor’s output relay.

Overvoltage sensor – The NC contacts are used. The relay remains de-

energized until an overvoltage is sensed.

Undervoltage sensor – The NO contacts are used. The relay remains en-

ergized until the voltage decreases to the preset level, where the sensor

de-energizes the relay.
