Filed: 1974-07-19
Abstract: 1474721 Voltage limit indicator HARTMANN & BRAUN AG 19 July 1974 [19 July 1973] 32142/74 Heading H3P A voltage limit indicator compares a limit value alternately with an actual value and a preset value and has a detector stage for monitoring a voltage waveform derived from the comparison. The limit value is set by potentiometer P2 as a negative voltage USOLL and is summed at the input to a trigger unit 2 alternately with the actual value U 1st  of a positive voltage and with a positive preset voltage set by P1, preferably preset to be slightly larger in magnitude U H  than U soll . When U 1st  is less than U soll  and U soll  less than U H  then an A.C. waveform is present at the output of the trigger 2, passes through coupling capacitor C, is rectified 3, and operates a relay 4. With input voltage, U 1st  higher than the limit U soll  the trigger 2 is permanently in the 1 state, there is no A.C. present and the relay is released. Similarly, if the limit U soll  rises because of a fault the trigger is permanently in the 0 state and the relay again releases. Further, any failure in the switch or trigger stops the A.C., and the relay is released. A separate meter (not shown) can be used to monitor U 1st  to distinguish between the various failure modes.
