The document describes a control-discrepancy switch that monitors and displays the circuit state of circuit breakers and disconnecting switches. It has two positions staggered by 90 degrees and can be turned 45 degrees further while pressing the switch button. It is used to control circuit breakers and indicate when their position does not match the switch position. The switch consists of nine contacts and a lighting unit to indicate discrepancies. It can operate in preselection circuits by first changing the graphical symbol to preselect a new circuit state before sending the switching command.

Version 03.2003 Control-Discrepancy Switch SM 2 Discrepancy Switch BM 2
2 The control-discrepancy switch is used to control circuit-breaker and disconnecting switch and to monitor and display their circuit state in mimic and illuminated mimic diagrams whereas the switch front is designed as graphical symbol. When it lights up it is indicated that the position of the control-discrepancy switch does not match with the assigned circuit breaker. The control- discrepancy switch can be operated in preselection circuits, i.e., the new switch position is preselected by change of the graphical symbol in the mimic diagram, then the switching command for the circuit-breaker is given. The control-discrepancy switch can also be used if control comes first and then the new circuit state is acknowledged. The control-discrepancy switch consists of a packet-type switch with nine wafers, the switching button with lighting unit and a breaker mechanism that has two latched positions staggered by 90属. Furthermore, this position can be turned in the same direction by 45属; however the switching button must be pressed, if not, the switch will jump back into its 90属 position. The 90属 rotary control switch is used for acknowledgement (signaling switch), and the +45属 press-and-twist switch (control switch) is used for control. The lightened switching button is designed in two versions as graphical symbol of the switch: black bar in white field, display is accomplished by lightening up of the white field white bar in black field, display is accomplished by lightening up of the white bar Both versions are equipped with a squared black front cover that can be removed, if necessary. The control-discrepancy switch is designed in such a way to match well with the general shape of the switchboard. The signaling switch has two latched positions staggered by 90属 and is operated by turning the switching button. For control purposes, the switch may be turned from these positions into the same direction by 45属, while the switching button must be pressed. When the switch is released, it jumps back into its 90属 position. Method of operation in the circuit "Preselection Control" Figures 1 to 3 of the Rs 801 280 circuit diagram (internal circuit diagram of Rs 801 362) show the control-discrepancy switch in the preselection circuitry. In figure 1, the control-discrepancy switch is in correspondence with the circuit-breaker. If the circuit state of the circuit-breaker is to be changed, preselection is accomplished by turning the control-discrepancy switch by 90属. After it is turned, the lamp lights up, thus indicating that the position of the control-discrepancy switch does not longer correspond with the circuit-breaker, see figure 2. The circuit-breaker is operated by pressing and turning the switching button by 45属, thus matching again with the switch position, the lamp is out, see figure 3. If the circuit-breaker changes its position, for example by release of a protective relay, the lamp lights up again. This message is acknowledged by turning the switching button of the control-discrepancy switch by 90属 to the other side (the lamp is out).

Three different circuit states for the control- discrepancy switch and the assigned circuit-breaker are shown. If the circuit state should be changed, see figure 1, the control contacts are closed and thus, the closing solenoid of the circuit-breaker is operated by pressing the switching button of the control-discrepancy switch by 45属 in excess of the 90属-position. After it is switched on, the lamp lights up thus indicating that the position of the control discrepancy switch does not longer correspond with the circuit-breaker, see figure 5. Correspondence of the switch position is reached again by turning the control-discrepancy into the "On" position, then the lamp is out, see figure 6. If requested, the signaling lamp can be operated with flashlight instead of permanent light through a clock generator which could be the same for several control-discrepancy switches in the unit.

4 Rs 801 281 diagram of connection: Figure 5 Rs 801 281 diagram of connection: Figure 6 The discrepancy switch is used as pilot switch to control switches and to monitor and display their circuit state in mimic and illuminated mimic diagrams of electrical installations as well as to indicate the position of valves in pipe systems. The switching button shows the position of the assigned switch and/or valve. When the rotary control switch button lights up it is indicated that the circuit state of the assigned switch and/or valve does not match with the position of the discrepancy switch. Therefore, the discrepancy switch is particularly suitable to be installed into units where the state of the switch should be monitored independently of the control point. The discrepancy switch consists of a packet-type switch with nine changeover contacts, the switching button with lighting unit and a breaker mechanism that has two latched positions staggered by 90属. The lightened switching button is designed in two versions as graphical symbol of the switch: black bar in white field, display is accomplished by lightening up of the white field white bar in black field, display is accomplished by lightening up of the white bar Both versions are equipped with a squared black front cover that can be removed, if necessary.

5 The signaling switch has two latched positions staggered by 90属 and is operated by turning the switching button. Mode of operation as discrepancy switch Figures 1 to 3 of the Rs 801 346 diagram of connection show an example for an application of a BM 2 discrepancy switch to monitor a circuit-breaker L in figure 1, switching state "OFF", and in figure 2, switching state "On" the position of the circuit- breaker L corresponds to that of the discrepancy switch M. In both cases the lamp m is not energized and the graphical symbol of the switch does not light up. If the position of the circuit-breaker L changes, for example if the switch is released by a protective relay, or by executing a switching command from another point, the circuit of the signaling lamp is closed, see figure 3. The graphical symbol of the switch lights up and indicates a new switching state. This message is acknowledged by changing the discrepancy switch, whereby the lamp goes out.

6 Mode of operation as a pilot switch In the circuit diagram Rs 801 347, the discrepancy switch is used as pilot switch. If, at the control, a switching operation is performed, the distribution station either receives the "On" or "Off" signal of the assigned switch and, then, gives the switching command. Simultaneously, the graphical symbol of the discrepancy switch is illuminated in the control. If the command is given, instruction sign and graphical symbol of the switch go out. The control necessarily and immediately gets informed on the execution of the switching command. Rs 801 347 diagram of connection: Figure 4 Mode of operation as alarm indicator According to the Rs 801 348 diagram, the BM 2 discrepancy switch can be used to indicate fault alarms for an optical or acoustic indication. If the protective relay shown in the initial state R switches over into the operated condition, the signal lamp m of the discrepancy switch M lights up and the acoustic signal goes on. When the discrepancy switch M changes into the warning position (bar in the switch front is horizontally), the signal lamp m goes out and the signal device H is switched off. The warning position of the discrepancy switch indicates that there is still a fault in the unit. If the protective relay goes back into its initial position, then lighting up of the signal lamp requires to set back the discrepancy switch. Rs 801 348 diagram of connection: Figure 5 In their mode of operation the switches are working independently of their position. They are suitable to be installed into switchboards of 1 to 15 mm thickness. After removing the switching button and screwing off the front ring, the switch is pushed from the backside through a 42 mm opening of the switchboard. Then, the front ring is screwed on again with or without the squared black front cover and the switching button is plugged on. After that, the switch has to be turned into the position according to the diagram and then be tightened from the backside by the two fastening screws. In the built-in state, the switches - from the operating side are provided with IP 40 degree of protection, from the terminal end (behind the switchboard) IP 00 degree of protection. According to the relevant instructions concerning the protection against electric shock the switches have to be installed safe to touch by the installer or, respectively, the operator observing the necessary measures. When exchanging the lamp, the operating handle should only be removed in the de-energized state of the lamp circuit.

  • 2. 2 The control-discrepancy switch is used to control circuit-breaker and disconnecting switch and to monitor and display their circuit state in mimic and illuminated mimic diagrams whereas the switch front is designed as graphical symbol. When it lights up it is indicated that the position of the control-discrepancy switch does not match with the assigned circuit breaker. The control- discrepancy switch can be operated in preselection circuits, i.e., the new switch position is preselected by change of the graphical symbol in the mimic diagram, then the switching command for the circuit-breaker is given. The control-discrepancy switch can also be used if control comes first and then the new circuit state is acknowledged. The control-discrepancy switch consists of a packet-type switch with nine wafers, the switching button with lighting unit and a breaker mechanism that has two latched positions staggered by 90属. Furthermore, this position can be turned in the same direction by 45属; however the switching button must be pressed, if not, the switch will jump back into its 90属 position. The 90属 rotary control switch is used for acknowledgement (signaling switch), and the +45属 press-and-twist switch (control switch) is used for control. The lightened switching button is designed in two versions as graphical symbol of the switch: black bar in white field, display is accomplished by lightening up of the white field white bar in black field, display is accomplished by lightening up of the white bar Both versions are equipped with a squared black front cover that can be removed, if necessary. The control-discrepancy switch is designed in such a way to match well with the general shape of the switchboard. The signaling switch has two latched positions staggered by 90属 and is operated by turning the switching button. For control purposes, the switch may be turned from these positions into the same direction by 45属, while the switching button must be pressed. When the switch is released, it jumps back into its 90属 position. Method of operation in the circuit "Preselection Control" Figures 1 to 3 of the Rs 801 280 circuit diagram (internal circuit diagram of Rs 801 362) show the control-discrepancy switch in the preselection circuitry. In figure 1, the control-discrepancy switch is in correspondence with the circuit-breaker. If the circuit state of the circuit-breaker is to be changed, preselection is accomplished by turning the control-discrepancy switch by 90属. After it is turned, the lamp lights up, thus indicating that the position of the control-discrepancy switch does not longer correspond with the circuit-breaker, see figure 2. The circuit-breaker is operated by pressing and turning the switching button by 45属, thus matching again with the switch position, the lamp is out, see figure 3. If the circuit-breaker changes its position, for example by release of a protective relay, the lamp lights up again.

  • 4. 4 Rs 801 281 diagram of connection: Figure 5 Rs 801 281 diagram of connection: Figure 6 The discrepancy switch is used as pilot switch to control switches and to monitor and display their circuit state in mimic and illuminated mimic diagrams of electrical installations as well as to indicate the position of valves in pipe systems. The switching button shows the position of the assigned switch and/or valve. When the rotary control switch button lights up it is indicated that the circuit state of the assigned switch and/or valve does not match with the position of the discrepancy switch. Therefore, the discrepancy switch is particularly suitable to be installed into units where the state of the switch should be monitored independently of the control point. The discrepancy switch consists of a packet-type switch with nine changeover contacts, the switching button with lighting unit and a breaker mechanism that has two latched positions staggered by 90属. The lightened switching button is designed in two versions as graphical symbol of the switch: black bar in white field, display is accomplished by lightening up of the white field white bar in black field, display is accomplished by lightening up of the white bar Both versions are equipped with a squared black front cover that can be removed, if necessary. The discrepancy switch is designed in such a way to match well with the general shape of the switchboard. 25 25 13 13 17 17 21 21 11 11 9 9 7 7 3 3 2 2 1 1 4 4 6 6 8 8 10 10 12 12 14 14 16 16 18 18 20 20 22 22 24 24 26 26 28 28 (E(A N N P P A A E E L L 2 2 2/ 2/ 1 1 4 4 3 3 (A (E EA EA Use Design BM 2 Discrepancy Switch
  • 5. 5 The signaling switch has two latched positions staggered by 90属 and is operated by turning the switching button. Mode of operation as discrepancy switch Figures 1 to 3 of the Rs 801 346 diagram of connection show an example for an application of a BM 2 discrepancy switch to monitor a circuit-breaker L in figure 1, switching state "OFF", and in figure 2, switching state "On" the position of the circuit- breaker L corresponds to that of the discrepancy switch M. In both cases the lamp m is not energized and the graphical symbol of the switch does not light up. If the position of the circuit-breaker L changes, for example if the switch is released by a protective relay, or by executing a switching command from another point, the circuit of the signaling lamp is closed, see figure 3. The graphical symbol of the switch lights up and indicates a new switching state. This message is acknowledged by changing the discrepancy switch, whereby the lamp goes out.

  • 6. 6 Mode of operation as a pilot switch In the circuit diagram Rs 801 347, the discrepancy switch is used as pilot switch. If, at the control, a switching operation is performed, the distribution station either receives the "On" or "Off" signal of the assigned switch and, then, gives the switching command. Simultaneously, the graphical symbol of the discrepancy switch is illuminated in the control. If the command is given, instruction sign and graphical symbol of the switch go out. The control necessarily and immediately gets informed on the execution of the switching command. Rs 801 347 diagram of connection: Figure 4 Mode of operation as alarm indicator According to the Rs 801 348 diagram, the BM 2 discrepancy switch can be used to indicate fault alarms for an optical or acoustic indication. If the protective relay shown in the initial state R switches over into the operated condition, the signal lamp m of the discrepancy switch M lights up and the acoustic signal goes on. When the discrepancy switch M changes into the warning position (bar in the switch front is horizontally), the signal lamp m goes out and the signal device H is switched off. The warning position of the discrepancy switch indicates that there is still a fault in the unit. If the protective relay goes back into its initial position, then lighting up of the signal lamp requires to set back the discrepancy switch. Rs 801 348 diagram of connection: Figure 5 In their mode of operation the switches are working independently of their position. They are suitable to be installed into switchboards of 1 to 15 mm thickness. After removing the switching button and screwing off the front ring, the switch is pushed from the backside through a 42 mm opening of the switchboard. Then, the front ring is screwed on again with or without the squared black front cover and the switching button is plugged on. After that, the switch has to be turned into the position according to the diagram and then be tightened from the backside by the two fastening screws. In the built-in state, the switches - from the operating side are provided with IP 40 degree of protection, from the terminal end (behind the switchboard) IP 00 degree of protection. According to the relevant instructions concerning the protection against electric shock the switches have to be installed safe to touch by the installer or, respectively, the operator observing the necessary measures. When exchanging the lamp, the operating handle should only be removed in the de-energized state of the lamp circuit.
