3 SUM 1001 SUM 1001 Voltage measuring relay For failing to meet and for exceeding the threshold value of single-phased voltages 3 operating ranges AC/DC: 0.5 to 500 V Curve shape: sine, square, triangle 10 time domains: non-delayed, 0.1 s to 3 h for the operate time delay Frequency range of the measured variable from 45 to 400 Hz Multifunction: Operating or rest current principle, hysteresis 3 % or 10 % of the target value Wiring diagram Applications Monitoring of voltage levels Monitoring of external voltage in mains with external supply Monitoring of field excitation in motors Monitoring of frequency actuators Monitoring of analog actuating variables Function The voltage measuring relay SUM 1001 is a monitoring relay for singlephase voltages. The measurand is supplied via various terminals, based on the desired operating range (see Table I). With the potentiometer target value, the response value can be set analogously within the preselected operating range. The operate time delay can be set with the time domain switch and the potentiometer time target value (see Table II). Notes: The supply voltage is galvanically separated from the measurement circuit and is displayed via the LED "SUPPLY". The measurand is recorded with an integrating full-wave rectification. With that, in certain limits, the monitoring of voltages, which are not sineshaped (e.g. voltages with a harmonic wave concentration, square or triangular voltages in the range of Hz) is possible. The devices assess (for AC) the rectification value calibrated to the effective value of a sine voltage. For DC measurands, a rectification occurs and the mean value is monitored. In the delay domain NO DELAY and with the simultaneously poweredon function measurand exceedance (> V) the monitoring relays respond as of a certain threshold to the present value of the measured variable, and the output relay toggles instantaneously (see technical data). Prior to the insulation or voltage test in the switching installation, the connector lines are to be disconnected from the voltage measuring relay. Function operating current principle After application of the supply voltage and the falling below or exceeding of the preselected response value (based on the function selection - see Table III), the output relay toggles to the operating position. This takes place either after the preselected response delay or immediately. If the response value - based on the setting - falls below or exceeds by at least 3 or 10 % (hysteresis), then the output relay returns to the Standby position. Function standby current principle After application of the supply voltage, the relay toggles to t B, to the operating position. If the preselected limit value falls below or exceeds (based on the function selection), then the output relay re-toggles to the Standby position, depending on the preselected delay time. According to the preselected hysteresis (3 or 10 %), the output relay re-toggles to the operating position after falling below or exceeding the response value.

After the elapse of the preselected operate time delay of 210 s, the output relay toggles to the operating position, and die LED TRIPPED stays on. If the actual value of the measured variable falls below the target value minus the 3% hysteresis, then the output relay retoggles to its Standby position. If the measurand falls below before reaching the preselected time, then the LED "TRIPPED" goes out (see function diagram 1).

If the actual value of the measured variable exceeds the target value plus the 10% hysteresis, then the output relay toggles to the operating position.

The measurand is supplied via different terminals based on the desired operating range (see Table I). With the potentiometer target value, the response value can be set analog within the preselected operating range. The operate time delay can be set with the time domains switch and the potentiometer time target value (see Table II). Notes: The supply voltage is galvanically separated from the measurement circuit and is indicated via the LED "SUPPLY". The measurand is recorded with an integrative full-wave rectification. Within certain limits, this enables the monitoring of currents which are not sine-shaped (e.g. currents with a concentration of harmonic waves, square or triangular currents ranging from Hz). For AC, the devices assess the rectification value calibrated to the effective value of a sine voltage. For DC measurands, rectification occurs and the mean value is monitored. In the delay domain NO DELAY and with simultaneously powered-on function "measurand exceed" (> A), the monitoring relays respond as of a certain threshold to the present value of the measured variable, and the output relay toggles instantaneously (see technical data). Prior to an insulation or voltage test on the switching installation, the connector lines are to be disconnected from the voltage measuring relay. Function operating current principle After application of the supply voltage and falling below and exceeding the preselected response value (based on the function selection - see Table III), the output relay toggles to the operating position. This occurs after the elapse of the preselected response delay or immediately, based on the selection. If the response value falls below or exceeds by at least 3% or 10 %, based on the setting (hysteresis), then the output relay falls back into the Standby position. Function standby current principle After application of the supply voltage, the relay t B toggles to the operating position. If the preselected limit value falls below or exceeds based on the function selection, then the output relay re-toggles to the Standby position depending upon the preselected delay time. Based on the preselected hysteresis (3 or 10 %), the output relay re-toggles to the operating position according to the corresponding falling below or exceeding the response value.

The measurand to be monitored current or voltage is supplied via the terminals B1/B2. The supply voltage circuit and the measurement circuit are galvanically separated by a transformer. On the relay, a response value and a fallback value are set. If the measurand exceeds the response value, then the relay toggles. If the measurand undershoots the fallback value, the relay returns to its default position. The fallback value is adjustable in the range of the response value. SXT 12 operating current principle When supply voltage is applied, the SXT 12 is in the Standby position. When the response value is exceeded, it toggles to the operating position. If the fallback value is undershot, then the relay re-toggles to the Standby position. SXT 32 standby current principle When supply voltage is applied, the SXT 32 toggles to the operating position.

12 SXT 12 Application examples Function diagrams RPM monitoring The RPM reading supplied by the tacho generator is converted to a voltage. This voltage (measurand) is monitored by the measuring relay SXT 32. If the voltage rises above the set response value, then the relay toggles to Standby position (standby current principle). The fault is indicated by Lamp H1. The flow is controllable via the SPS. Operate time Current monitoring in the consumer load If the current in the consumer load (measurand) rises above the set response value, then the relay toggles to Standby position (standby current principle). The fault is indicated by Lamp H1. if the current decreases below the fallback value, then the relay re-toggles to the operating position. The operate time is the time between the occurrence of a measurand and the toggle of the relay. It is influenced by way of the factor by which the measurand exceeds the response value. The permissible fault impulse width is the duration of the fault impulse at which the relay does not yet respond.

After this time lapses, the SBW 1004 monitors the preselected phase shift cos ϕ (in <)). When the load decreases, the phase shift increases cos ϕ decreases. If the preselected phase shift is exceeded, then the relay toggles to the operating position after the elapse of the fixed operate time. After the undershoot of the preselected phase shift once again normal load and the elapse of the fixed fallback time, the relay re-toggles to the Standby position. The fixed response and fallback time (1000 ms) prevents the relay from responding in the event of short-term target value deviations. SBW 1005 standby current principle With the application of the supply voltage, the relay toggles to the operating position. When the motor is connected, the start-up bridging time (adjustable on the relay) begins. After the elapse of this time, the SBW 1005 monitors the preselected phase shift cos ϕ (in <)). When the load decreases, the phase shift increases cos ϕ decreases. If the preselected phase shift is exceeded, the relay then toggles to Standby position after the elapse of the fixed operate time. After the undershoot of the preselected phase shift once again normal load and the elapse of the fixed fallback time, the relay re-toggles to the operating position. The fixed response and fallback interval (1000 ms) prevents the relay from responding in the event of short-term target value deviations. SBW 1004/SBW 1005 with error memory The error memory is started by bridging the connectors Y1, Y2. After falling below the preselected Phase shift once again normal load the relay remains in operating position/standby position. Only upon reset is the fault memory deleted; the relay toggles to Standby position/operating position. If the preselected phase shift remains exceeded, then the relay only re-toggles to the Standby position/operating position during reset. Page 120 SBW 1004 Subject to change without further notice

If too little loose material is supplied decreasing load then the relay toggles to the operating position after the elapse of the fixed operate time. Dust filter monitoring The load monitor SBW 1005 monitors the filter for dirt. If the filter is dirty, the motor's load decreases cos ϕ decreases. If the preselected phase shift is exceeded, the relay toggles to Standby position after the elapse of the fixed operate time standby current principle. The fault remains saved until the manual reset via the Reset button. Dimensional drawing Inductive load Principle When inductive load is applied, the current lags behind the voltage to an extent equal to the phase angle ϕ. When the load on the motor decreases, the phase angle increases - and with that, the cos ϕ decreases. This phase angle change is an exact measure of the change in load on the motor shaft.

At a motor nominal current > 5 A, a current transformer must be used. The current transformer must be designed for a burden of R I + 2 x R L. terminals k and L1 must always lie on the same phase. For the terminals L1, L2, L3: keep turned to the right. Accessories Applications Machine tools: Safeguarding of the motors from low load, e.g. by: - Recognition of tool destruction and tool wear - Optimization of cutting powers and tool infeeds - Forward and backward control of screw thread cutting machines Contact pressure optimization on rollers and presses Regulation of the conveyance quantity and actuation power to conveyors and means of transport Monitoring of slip and the destruction of v-belts Motion detection at roll gates Idle monitoring and conveyance quantity regulation for pumps Regulation of the conveyance quantity of air in A/C units Check of level following in wash brushes and wear in large-scale wash installations for cars, trucks, buses and rail vehicles Consistency monitoring for agitation matter in agitators Function Standby current principle With the application of the supply voltage, the relay toggles to the operating position. When the motor is connected, the start-up bridge time (adjustable on the relay)begins. After the elapse of this time, the SBW 1007 monitors the preselected phase shift cos ϕ (in <)). When the load increases, the phase shift decreases cos ϕ increases. If the preselected phase shift is undershot, then the relay toggles to the Standby position after the elapse of the fixed operate time After exceeding preselected Phase shift once again normal load and elapse of the fixed fallback time, the relay re-toggles to the operating position. The fixed response and fallback interval(1000 ms) prevents the relay from responding in the event of short-term target value deviations. Error memory The error memory is started by bridging the connectors Y1, Y2. After the undershoot of the preselected Phase shift once again normal load the relay remains in operating position/standby position. Only by Reset (Reset) is the fault memory deleted; the relay toggles to Standby position/operating position. If the preselected phase shift remains exceeded, then the relay only toggles to the Standby/operating position during reset. Subject to change without further notice SBW 1007 Page 123

33 SBW 1007 Application examples Function diagram Roller monitoring The load monitor SBW 1007 monitors the roller contact pressure. When the roller contact pressure increases, then the motor load also increases (cos ϕ increases). When the preselected Phase shift is undershot, the relay toggles to the Standby position (standby current principle). Dimensional drawing Breaker monitoring The load monitor, in turn, monitors the stone crusher for overload. If the preselected phase shift is undershot, due to increasing motor load (e.g. due to jamming), the load monitor toggles. The fault remains saved until resetting with the Reset button. Inductive load Principle When inductive load is applied, the current lags behind the voltage at a rate equal to the phase angle ϕ. If the motor load decreases, the phase angle increases - and with that, the cos ϕ decreases. This phase angle change is an exact measure of the load change on the motor shaft. The load monitor, in turn, monitors the phase shift between voltage and current when inductive loads are present in the sine-shaped alternating and rotary current grid (not suitable for phase section control and frequency-regulated motors).

This is analyzed by the STW. The compensator lines serve to extend the thermal elements (principle wiring diagram). They are laid from the connector of the thermal element to the comparison point (compensator socket, measuring point toggle). Compensator lines consist of positive and negative conductors. Up to a maximum limit of C, they have the same thermo-electric properties as the thermal element. Therefore, no thermal tension occurs at the connector points. The maximum temperature for compensator lines is considered C, independent of the insulation material. If the temperature at the connector point is higher, a thermal line must be used in place of the compensator line in order to achieve a high level of metering precision. The production of compensator lines is less complex than that of thermal lines. They usually have a larger cross-section and lower electrical resistance. Therefore, they are more efficient for greater line lengths. Subject to change without further notice STW 1001 / 1002 Page 135
