Voltage monitoring relays CM-ESS.2
for single-phase AC/DC voltages
For the monitoring of voltages in single-phase
AC/DC systems, ABB’s CM range comprises a
wide selection of powerful and compact devices,
all featuring only 22.5 mm (0.89 in) width.
This range includes voltage monitoring relays for
over- and undervoltage protection from 3 V to
600 V.

Application
Depending on the configuration, the voltage monitoring relays CM-ESS.2 can be used for over- d or undervoltage
monitoring c in single-phase AC and/or DC systems. The devices work according to the open-circuit principle.
Operating mode
The voltage monitoring relay CM-ESS.2 has 2 c/o contacts. One device includes 4 measuring ranges:
3-30 V, 6-60 V, 30-300 V, and 60-600 V.
The unit is adjusted with potentiometers and switches on the top of the unit. The selection of over- d or undervoltage
monitoring c is made with a DIP switch . Potentiometers, with direct reading scale, allow the adjustment of the threshold
value U, of the hysteresis % and of the tripping delay TV. The hysteresis % is adjustable within a range of 3 to 30 % of the
threshold value, and the tripping delay TV over a range of instantaneous to a 30 s delay.

Function diagram: overvoltage monitoring
d
The voltage to be monitored (measured value) is applied to terminals B-C. The supply voltage applied to terminals A1-A2 is
displayed by the glowing green LED.
If the measured value exceeds the adjusted threshold value, the tripping delay TV starts and the red LED (overvoltage)
glows. Timing of TV is displayed by the flashing W green LED. When TV is complete and the measured value still
exceeds the threshold value minus the adjusted hysteresis, the output relays energize and the yellow LED (relay energized)
glows.
If the measured value drops below the threshold value minus the adjusted hysteresis, the output relays de-energize and the
red and yellow LEDs turn off.

The voltage to be monitored (measured value) is applied to terminals B-C. The supply voltage applied to terminals A1-A2 is
displayed by the glowing green LED.
If the measured value decreases below the adjusted threshold value, the tripping delay TV starts and the red LED
(undervoltage) flashes W . Timing of TV is displayed by the flashing W green LED. When TV is complete and the
measured value is still below the threshold value plus the adjusted hysteresis, the output relays energize and the yellow LED
(relay energized) glows.
If the measured value exceeds the threshold value plus the adjusted hysteresis, the output relays de-energize and the red
and yellow LEDs turn off.
