Voltage monitoring relay CM-EFS.2  
For single-phase AC/DC voltages  
The CM-EFS.2 is an electronic voltage monitoring  
relay that provides reliable monitoring of voltages  
as well as detection of phase loss.  
All devices are available with two different terminal  
versions. You can choose between the proven  
screw connection technology (double-chamber  
cage connection terminals) and the completely  
tool-free Easy Connect Technology (Push-in  
terminals).

Application  
The voltage monitoring relays CM-EFS.2 are designed for use in single-phase AC and/or DC systems for the simultaneous  
monitoring of over- or undervoltages as well as detection of phase loss. Depending on the configuration, one c/o (SPDT)  
contact each or both c/o (SPDT) contacts in parallel can be used for the over- and undervoltage monitoring. The devices  
operate over an universal range of supply voltages and provide an adjustable tripping delay. Open or closed-circuit principle  
as well as ON of OFF delay tripping are configurable.  
Operating mode  
The CM-EFS.2 have 2 c/o (SPDT) contacts and include 4 measuring ranges: 3-30 V, 6-60 V, 30-300 V and 60-600 V.  
The units are adjusted with front-face operating controls. The selection of: ON-delay A or OFF-delay B, open- h or  
closed-circuit principle g, latching function ON f or OFF e and 2x1 c/o i or 1x2 c/o (SPDT) contacts j is made  
with DIP switches. Potentiometers, with direct reading scale, allow the adjustment of the threshold valuemax (>U) for  
overvoltage, the threshold valuemin (<U) for undervoltage and the tripping delay TV . The tripping delay TV is adjustable over  
a range of instantaneous to a 30 s delay. The hysteresis is fixed at 5 %. Timing is displayed by a flashing green LED labelled  
U/T.

Voltage window monitoring 1x2 c/o (SPDT) contacts jON-delayed Awithout latching e  
Open-circuit principle h  
The voltage to be monitored (measured value) is applied to terminals B-C. The control supply voltage applied to terminals  
A1-A2 is displayed by the glowing green LED.  
If the measured value exceeds the threshold valuemax (>U) or drops below the threshold valuemin (<U), the tripping delay TV  
starts and the red LED glows (overvoltage), or flashes W(undervoltage) respectively.  
Timing of TV is displayed by the flashing Wgreen LED.  
When TV is complete and the measured value still exceeds the threshold valuemax minus the fixed hysteresis (5 %) or is still  
below the threshold valuemin plus the fixed hysteresis (5 %), the output relays energize and the yellow LED (relay energized)  
glows.  
If the measured value decreases below the threshold valuemax minus the fixed hysteresis (5 %) or exceeds the threshold  
valuemin plus the fixed hysteresis (5 %), the output relays de-energize and the red and yellow LEDs turn off.  
If control supply voltage is interrupted, the green LED turns off.  
Closed-circuit principle g  
The voltage to be monitored (measured value) is applied to terminals B-C. When control supply voltage is applied to  
terminals A1-A2, the output relays energize and the green and yellow LED (relays energized) glow.  
If the measured value exceeds the threshold valuemax (>U) or drops below the threshold valuemin (<U), the tripping delay TV  
starts and the red LED glows (overvoltage), or flashes W(undervoltage) respectively.  
Timing of TV is displayed by the flashing Wgreen LED.  
When TV is complete and the measured value still exceeds the threshold valuemax minus the fixed hysteresis (5 %) or is  
still below the threshold valuemin plus the fixed hysteresis (5 %), the output relays de-energize and the yellow LED (relays  
energized) turns off.  
If the measured value decreases below the threshold valuemax minus the fixed hysteresis (5 %) or exceeds the threshold  
valuemin plus the fixed hysteresis (5 %), the output relays re-energize, the yellow LED glows and the red LED turns off.  
If control supply voltage is interrupted, the output relays de-energize and the yellow and green LEDs turn off.

Open-circuit principle h  
The voltage to be monitored (measured value) is applied to terminals B-C. The control supply voltage applied to terminals  
A1-A2 is displayed by the glowing green LED.  
If the measured value exceeds the threshold valuemax (>U) or drops below the threshold valuemin (<U), the output relay 1115-  
1216/1418 (>U), or 2125-2226/2428 (<U) respectively, energizes, the yellow LED (relays energized) flashes Zand the red  
LED glows (overvoltage), or flashes W(undervoltage) respectively.  
If the measured value decreases below the threshold valuemax minus the fixed hysteresis (5 %) or exceeds the threshold  
valuemin plus the fixed hysteresis (5 %), the red LED turns off. The output relay 1115-1216/1418 (>U), or 2125-2226/2428 (<U)  
respectively, remains energized (latching function).  
If control supply voltage is interrupted (reset), the output relays de-energize and the yellow and green LEDs turn off.  
Closed-circuit principle g  
The voltage to be monitored (measured value) is applied to terminals B-C. When control supply voltage is applied to  
terminals A1-A2, the output relays energize and the green and yellow LED (relays energized) glow.  
If the measured value exceeds the threshold valuemax (>U) or drops below the threshold valuemin (<U), the output relay 1115-  
1216/1418 (>U), or 2125-2226/2428 (<U) respectively, de-energizes, the yellow LED (relays energized) flashes Yand the  
red LED glows (overvoltage), or flashes W(undervoltage) respectively.  
If the measured value decreases below the threshold valuemax minus the fixed hysteresis (5 %) or exceeds the threshold  
valuemin plus the fixed hysteresis (5 %), the red LED turns off. The output relay 1115-1216/1418 (>U), or 2125-2226/2428 (<U)  
respectively, remains de-energized (latching function).  
If control supply voltage is interrupted (reset), the yellow and green LEDs turn off. The output relays energize again when  
control supply voltage is re-applied.
