9 / 18 page Data sheet | Voltage monitoring relay CM-EFS.2 - 9 Voltage window monitoring 2x1 c/o (SPDT) contact i OFF-delayed B without 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 output relay 1115-1216/1418 (>U), or 2125-2226/2428 (<U) respectively, energizes, the yellow LED (relays energized) glows and 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 tripping delay TV starts and the red LED turns off. Timing of TV is displayed by the flashing W green LED. When TV is complete, the output relay 1115-1216/1418 (>U), or 2125-2226/2428 (<U) respectively, de-energizes and the yellow LED (relay energized) turns 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 output relay 1115-1216/1418 (>U), or 2125-2226/2428 (<U) respectively, de-energizes, the yellow LED turns off and 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 tripping delay TV starts and the red LED turns off. Timing of TV is displayed by the flashing W green LED. When TV is complete, the output relay 1115-1216/1418 (>U), or 2125-2226/2428 (<U) respectively, energizes and the yellow LED (relay energized) glows. If control supply voltage is interrupted, the output relays de-energize and the yellow and green LEDs turn off.
