Voltage window monitoring 2x1 c/o (SPDT) contact

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.

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.
