Ordering details The current window monitoring relays CM-SFS. can be used for the simultaneous monitoring of over- (>I) and undercurrents (<I) in single-phase AC and/or DC systems. Depending on the configuration, one c/o contact each i or both c/o contacts in parallel j can be used for the over- and undercurrent monitoring. The current to be monitored (measured value) is applied to terminals B/B/B3-C. Open- h or closed-circuit principle g as well as an adjustable ON A or OFF tripping B delay are configurable. ON-delayed A current window monitoring with parallel switching c/o contacts j: If the measured value exceeds resp. drops below the adjusted threshold value before the set start-up delay T S is complete, the output relays do not change their actual state. If the measured value exceeds resp. drops below the adjusted threshold value when T S is complete, the tripping delay T V starts, when A is configured. If T V is complete and the measured value is still exceeding resp. below the threshold value minus resp. plus the fixed hysteresis (5%), the output relays energize h /de-energize g. If the measured value exceeds resp. drops below the threshold value plus resp. minus the hysteresis and the latching function is not activated f, the output relays de-energize h / energize g. With activated latching function e the output relays remain energized h and de-energize only, when the is interrupted / the output relays remain de-energized g and energize only, when the is switched off and then again switched on = Reset. OFF-delayed B current window monitoring with parallel switching c/o contacts j: If the measured value exceeds resp. drops below the adjusted threshold value when the set start-up delay T S is complete, the output relays energize h / de-energize g, when B is configured, and remain in this position during the set tripping delay T V. If the measured value exceeds resp. drops below the threshold value plus resp. minus the fixed hysteresis (5%) and the latching function is not activated e, the tripping delay T V starts. After completion of T V, the output relays de-energize h / energize g, provided that the latching function is not activated e. With activated latching function f the output relays remain energized h and de-energize only, when the is interrupted / the output relays remain de-energized g and energize only, when the is switched off and then again switched on = Reset. When i is adjusted on the device, the functionality is equivalent to the one described above. There is only to consider that in this case, instead of both output relays, only one output relay each will be switched. >I = 5-6 /4 8 ; <I = 5-6 /4 8 Function diagrams CM-SFS.

Ordering details The voltage window monitoring relay CM-EFS. can be used for the simultaneous monitoring of over- (>U) and undervoltages (<U) in single-phase AC and/or DC systems. Depending on the configuration, one c/o contact each i or both c/o contacts in parallel j can be used for the over- and undervoltage monitoring. The voltage to be monitored (measured value) is applied to terminals B-C. Open- h or closed-circuit principle g as well as an adjustable ON A or OFF tripping B delay are configurable. ON-delayed A voltage window monitoring with parallel switching c/o contacts j: If the measured value exceeds resp. drops below the adjusted threshold value, the tripping delay T V starts, when A is configured. If T V is complete and the measured value is still exceeding resp. below the threshold value minus resp. plus the fixed hysteresis (5%), the output relays energize h /de-energize g. If the measured value exceeds resp. drops below the threshold value plus resp. minus the hysteresis and the latching function is not activated e, the output relays de-energize h / energize g. With activated latching function e the output relays remain energized h and de-energize only, when the is interrupted / the output relays remain de-energized g and energize only, when the is switched off and then again switched on = Reset. OFF-delayed B voltage window monitoring with parallel switching c/o contacts j: If the measured value exceeds resp. drops below the adjusted threshold value, the output relays energize h / de-energize g, when B is configured, and remain in this position during the set tripping delay T V. If the measured value exceeds resp. drops below the threshold value plus resp. minus the fixed hysteresis (5%) and the latching function is not activated e, the tripping delay T V starts. After completion of T V, the output relays de-energize h / energize g, provided that the latching function is not activated e. With activated latching function e the output relays remain energized h and de-energize only, when the is interrupted / the output relays remain de-energized g and energize only, when the is switched off and then again switched on = Reset. When i is adjusted on the device, the functionality is equivalent to the one described above. There is only to consider that in this case, instead of both output relays, only one output relay each will be switched. >U = 5-6 /4 8 ; <U = 5-6 /4 8 Function diagrams CM-EFS.

If all three phases are present, the output relay is energized. If the above fault occurs, the output relay is de-energized and the yellow LED turns off. The relay is re-energized automatically as soon as the voltage returns to the nominal range, taking into account a fixed hysteresis.

In case of motors which continue running with only two phases, the CM-PFE detects phase loss if the reverse feeded voltage is less than 60% of the nominal voltage.

It is able to monitor the phase parameters phase sequence, phase loss, over- and undervoltage. If all three phases are present with correct voltage, the output relays are energized. If the voltage to be monitored exceeds or falls below the fixed threshold value, the output relays are de-energized undelayed or delayed (0.-0 s), depending on the set time delay.

Switch position A: In case of a fault, the de-energizing of the output relays and the respective fault signal are suppressed for the set delay time. Switch position B: In case of a fault, the output relays de-energize immediately and a fault signal is issued and stored for the set delay time.

24 Three-phase monitoring relays for unbalance - CM-PAS Ordering details CDC F0t04 The CM-PAS is a three-phase monitoring relay. It is able to monitor the phase parameters phase sequence, phase loss and phase unbalance. If all three phases are present with correct voltage, the output relay is energized. The output relays are de-energized delayed (0.-0 s), if the phase unbalance of the phases to be monitored exceeds the set unbalance threshold value. This enables a short-term suppression of fault signals or, for better evaluation, a storage of the fault signal. The fault type is indicated by LEDs. The output relays re-energize undelayed, as soon as the voltage returns to the tolerance range, taking into account a fixed hysteresis of 0%. Phase sequence and phase loss are indicated and reset without time delay.

It is able to monitor the phase parameters phase sequence, phase loss, over- and undervoltage and phase unbalance. The threshold values for over- and undervoltage are adjustable (see table). The threshold value for phase unbalance can be adjusted from -5 %. If one of the above faults occurs, the output relay is de-energized. The fault type is indicated by LEDs. The fault signal can be suppressed or, for better evaluation, stored for the settable delay time of 0. to 0 s. The sliding switch A / B is used to select the delay time function. Switch position A: In case of a fault, the de-energizing of the output relays and the respective fault signal are suppressed for the set delay time. Switch position B: In case of a fault, the output relays de-energize immediately and a fault signal is issued and stored for the set delay time. This way, also momentary undervoltage conditions are recognized. The output relay is re-energized automatically if all parameters are back within the adjusted limits.

32 Insulation monitors for ungrounded supply mains Insulation monitoring in IT systems Overview, Application and connection examples The IT system with additional equipotential bonding and insulation monitoring equipment The IT system is supplied either by an isolation transformer or an independent voltage source, such as a battery or a generator. In this system no active conductor is directly connected to earth potential.the advantage of this is that only a small fault current can flow in case of an insulation fault. This current is essentially caused by the system's leakage capacitance. The system's fuse does not respond, thus maintaining the voltage supply and therefore operation even in case of a phase-to-earth fault. The high reliabilitity of an IT system is guaranteed thanks to continuous insulation monitoring. The insulation monitoring device recognizes insulation faults as they develop, and immediately reports that the value has fallen below the minimum. This prevents operational interruptions caused by a second more severe insulation fault. The following illustration shows the typical arrangement of an IT system. In IT-N systems the secondary side star point of the transformer is additionally used as neutral.

It is primarily used to monitor auxiliary circuits that are electrically isolated from ground. The CM-IWN-AC monitors the insulation resistance between ungrounded AC s and the protective earth conductors. A superimposed DC measuring voltage is used for measurement. The CM-IWN-AC is designed for insulation resistances to be monitored from to 0 kq, divided into two ranges. The desired range is selected with a front-mounted switch. The output relay is energized and the LED lights up as soon as the insulation resistance R x falls below the threshold value. The relay is reset (de-energized) automatically if the measured insulation resistance exceeds.6 times the threshold value. An earth-leakage fault can be simulated using the front-mounted "Test" button. A remote test button can be connected via the terminals S-. Tripping is caused by closing a n/o contact. By jumpering the terminals S-S, fault tripping can be stored. Remote reset can be implemented by connecting a pushbutton to S-S. Pressing the button then resets storage of the tripped state. Attention! The CM-IWN-AC is designed for AC s. Rectifiers, that are connected in series, should be electrically isolated from the measuring relay. Function diagram CM-IWN-AC CM- IWN-AC A-A/B S-S / or S- Insulation resistance R of the supply Set response.6x R x threshold R x t T t T = t Test > approx. 300 ms Rated control 4-40 V AC/DC 0-30 V, 0-40 V AC Operating principle The control is feeded via terminals A-A/ B. This can be the voltage supplied from the system to be monitored. The CM-IWN superimposes DC-voltage on the system to be monitored via the terminals L and (one phase or, if available, the neutral). In case of earth-leakage the resistance of the system against earth potential changes. The resulting earthleakage current overcomes the insulation resistance (<). If this earth-leakage current exceeds the adjusted response threshold, the output relay is energized with delay (see characteristic) and the red "fault" LED lights up. Fields of application The insulation resistance monitor CM-IWN-AC is mainly used in industrial applications with electrically insulated AC systems for the measurement of an occurring first isolation fault. This can prevent the installation from incorrect operation caused by a possible second isolation fault. The resistances R and R correspond to two subsequent isolated faults (see drawing). In this case, the resistances are connected in series related to earth potential which would prevent contactor K from being de-energized (fault!) although auxiliary contact K is open. This incorrect operation may cause considerable faults within the installation.

Due to its electrical isolation between the supply circuit and the measuring circuit, it can be supplied either by an external auxiliary voltage or by the to be monitored. The CM-IWN-DC is mainly used to monitor DC auxiliary circuits that are electrically isolated from primary circuits as well as installations powered by batteries. Insulation resistance faults are evaluated separately for L+ or L- and displayed by LEDs. Due to its measuring principle, the CM-IWN-DC is not able to detect balanced earth-leakage faults. The response threshold is adjustable in a range from 0-0 kq. If the insulation resistance falls below the set response threshold, the relay is energized and the error LED lights up.

42 Motor load monitors Fields of application The motor load monitor monitors the load states of single-phase and three-phase asynchronous motors. The evaluation of the phase angle between current and voltage allows a very precise monitoring of the load states. Compared with other conventional measuring principles (e.g. pressure transducers, current measurement), cos ϕ monitoring is a more precise and economical alternative. The motor is used as a sensor for its own load status. Main applications Pump monitoring Dry-running protection (underload) Closed valves (overload) Pipe break (overload) Heating, air-conditioning, ventilation Monitoring of filter pollution V-belt breakage (underload) Closed shutters/valves (overload) Air ventilating volume Agitating machines High consistency within the tank (overload) Pollution of the tank (overload) Transport/Conveyance Congested conveyor belts (overload) amming of belts (overload) Material accumulation in spiral conveyors (overload) Lifting platforms Machine installation Wear of tools, e.g. worn saw blades in circular saws, etc. (overload) Tool breakage (underload) V-belt drives (breakage underload) Pump control Dry-running protection Starting time delay Response delay Ventilator monitoring V-belt monitoring SVC F 0470 Detected fault - installation is switched off SVC F 047 Filter pollution Starting time delay Response delay Filter pollution Detected fault - installation is switched off SVC F 0473 SVC F 047 Starting time delay Detected fault - installation is switched off Starting time delay Detected fault - installation is switched off Wiring examples (for motor currents 0 A) Wiring examples (for motor currents 0 A) Hz L L L3 N Hz L N Hz L L L3 N k K l L K U V W M 3~ SVC F 03 K U U M ~ SVC F 03 K U V W M 3~ SVC F 03 ~ ~ Hz V, Hz L L L3 N 0-40 V Hz L L L Hz L N k K l L K U V W M 3~ SVC F 033 DC AC K U V W M 3~ SVC F 033 K U U M ~ SVC F 03 Current transformers ABB CDC0004C005

The primary application is the monitoring of single- or three-phase asynchronous motors (squirrel cage) under varying load conditions. The measuring principle is based on the evaluation of the phase shift (ϕ) between the voltage and the current in one phase. The phase difference is nearly inversely proportional to the load. Therefore, cos ϕ, measured relatively from 0 to, measures the relationship of effective power to apparent power. A value towards 0 indicates low load and a value towards indicates high load. Threshold values can be set individually for cos ϕ max and cos ϕ min If the set threshold value is reached, a LED lights up and the relay is de-energized. If cos ϕ returns to the acceptable limits (taking into account the hysteresis), the relay is reset to its original state and the LED flashes permanently to indicate the occurrence of the trip event. This message can be deleted using the reset button or by switching off the supply. A time delay (Time S) of 0.3 to 30 s can be set for the starting phase of the motor. It is also possible to set a response delay time (Time R) of 0. to s to suppress unwanted tripping due to unavoidable short load changes during normal operation. To guarantee correct operation of the response delay (Time R), the adjusted value for cos ϕ max has to be higher than the value for cos ϕ min plus the hysteresis. Consequently, the overload and underload indication must not be active at the same time. Due to the internal electrical isolation of the supply circuit and the measuring circuit, it is also possible to use the device in systems with different s.

46 Thermistor motor protection relays CM-MSE, CM-MSS, CM-MSN Benefits and advantages, Selection table Operating principle and fields of application for thermistor motor protection relays The CM range of thermistor motor protection relays are used to control motors equipped with PTC temperature sensors. The PTC temperature sensors are incorporated in the motor windings to measure the motor heating. This enables direct control and evaluation of the following operating conditions: heavy duty starting increased switching frequency single-phase operation high ambient temperature insufficient cooling break operation unbalance The relay is independent of the rated motor current, the insulation class and the method of starting. The PTC sensors are connected in series to the terminals Ta and Tb (or Ta and Tbx without short-circuit detection). The number of possible PTC sensors per measuring circuit is limited by the sum of the individual PTC sensor resistances. RG = R + R + RN m.5 kq. Under normal operating conditions the resistance is below the response threshold. If only one of the PTC resistors heats up excessively, the output relay is de-energized. If the autoreset function is configured, the output relay is re-energized automatically after cooling down. Devices with manual (pushbutton on front-side) or remote reset configuration have to be controlled via the control input by the required signal.

For instance, in case of three-phase squirrel cage motors, three sensors are embedded in the stator windings. For pole-changing motors with one winding (Dahlander connection), 3 sensors are also sufficient. Pole-changing motors with two windings, however, require 6 sensors. If an additional warning is required before the motor is switched off, separate sensors for a correspondingly lower temperature must be embedded in the winding. They have to be connected to a second control unit. The sensors are suitable for embedding in motor windings with rated operating voltages of up to 660 V AC. Conductor length: 500 mm per sensor. A 4 V varistor can be connected in parallel to protect the sensors from overvoltage.

56 Temperature monitoring relays C5x range Overview, functional description and diagrams Overview The C5x temperature monitoring relays can be used for temperature measurement in solid, liquid and gaseous media. The temperature is acquired by the sensor in the medium, evaluated by the device and monitored to determine whether it is within an operating range (range monitoring function) or has exceeded or fallen below a threshold. Functional description Analog tripping devices Once the temperature has reached the set threshold, output relay K changes its switching state. In devices with thresholds relay K reacts correspondingly if the second threshold is reached. No time delay can be set (t = 0). The relays immediately return to their original switching state if the temperature reaches the set hysteresis value. Once the temperature has reached the upper threshold of υ, output relay K changes its switching state after the set time t. The relay immediately returns to its original switching state if the temperature reaches the set hysteresis value. K reacts correspondingly at the lower threshold value of υ. Once the temperature has reached the set threshold of υ, output relay K changes its switching state after the set time t has elapsed. (K reacts in the same way at υ). The relays return to their original state if the temperature drops below the set hysteresis value and the connection Y-Y is interrupted for a short time. Digital tripping devices Once the temperature has reached the set threshold of υ, output relay K changes its switching state after the set time delay t has elapsed (K reacts in the same way for υ). Characteristic curves of resistance sensors Resistance in NTC KTY83 KTY84 PT000 PT Temperature in C CDC F007 The family is composed of analog adjustable devices with one or two thresholds, and digital devices which are a good alternative especially in the low-end range. The output relay switches on or off at the thresholds, depending on the configured functionality (open- or closed-circuit principle selectable).

The resulting systematic errors must be taken into account when adjusting the tripping device. A jumper must be connected between the terminals T and T3. The following table can be used for PT00 sensors to determine the temperature errors caused by the line length. ATTENTION! When using resistance sensors with two-wire connection a bridge must be inserted between terminals T and T3. SVC F005 3-wire measurement To minimize the influence of the wire resistance, a three-wire connection is usually used. By means of the additional wire two measuring circuits are created. One of these two circuits is used for reference. This way, the tripping device can calculate and take into account the wire resistance automatically. SVC F006 Error caused by the line The error resulting from the line resistance amounts to approx..5 Kelvin/Ohm. If the resistance of the line is not known and it is not possible to measure it, the error caused by the line can be estimated using the following table.

61 Liquid level relays CM-ENS Ordering details The CM-ENS monitors levels of conductive liquids and is used for example for liquid level control in pump systems. It can be used for filling or draining tanks for example. SVR F00 It is also suitable for monitoring the conductivity of liquids. The measuring principle is based on the resistance change sensed by single-pole electrodes. After the is applied to the terminals A and A, the output relay is de-energized. The probes must be connected to C, MAX, MIN. The output relay energizes if the liquid exceeds the maximum level (C and MAX wet) and de-energizes if the liquid level is below the minimum level (MAX and MIN dry). Based on the measuring circuit there will be a response delay of approx. 50 ms at maximum sensitivity. Different levels in one tank can be controlled by up to 5 CM-ENS without interfering with each other.

The measuring principle is based on the resistance change sensed by single-pole electrodes. The output relay functions fill (UP) or drain (DOWN) can be selected on a front-face selector switch. If the "UP" function is selected, the output relay is energized until the MAX electrode becomes wet. Then it is de-energized and not re-energized until the MIN electrode becomes dry. If the "DOWN" function is selected, the output relay is energized as soon as the MAX electrode becomes wet. It remains energized until the liquid level has dropped below the MIN electrode. The electrodes can be connected to more than one CM-ENS unit without interference.

63 Liquid level relays CM-ENN Ordering details SVR F0000 The CM-ENN monitors levels of conductive liquids and is used for example for liquid level monitoring in pump control systems, for dry-running protection of submersible pumps or overflow monitoring of tanks. It is also suitable for conductivity monitoring of liquids. The measuring principle is based on the resistance change sensed by single-pole electrodes (wet or dry). Instead of electrodes, other sensors or transducers can also be used if their output quantities are different resistance values. The measuring, output and supply circuits are electrically isolated for potential separation and to prevent electrical interference. Due to the integrated ON- or OFF-delay, it is possible to set up time-dependent liquid controls using only two electrodes (C, MAX). Different liquid levels in one tank can be controlled by up to 5 CM-ENN (AC version) without mutual interference.

After all electrodes have been wetted by the liquid being monitored, turn the sensitivity potentiometer towards maximum value (00) until the relay energizes. If the relay does not energize, select a higher q value (sector) on the device and proceed as before. Then it has to be checked if the relay de-energizes properly as soon as the electrodes C and MIN are no longer wet. Liquid levels higher than the maximum level electrode can be obtained by setting an ON-delay (TA = s). Liquid levels lower than the minimum level electrode can be obtained by setting an OFF-delay time (TR = s), e.g. for emptying tanks.

64 Liquid level relays - Liquid level control with two alarm outputs - CM-ENN UP/DOWN Ordering details SVR F000 The CM-ENN UP/DOWN monitors levels of conductive liquids and media and is used e.g. for liquid level control in pump systems. The measuring principle is based on the resistance change sensed by singlepole electrodes. The function of the output relay -/4 can be selected by a selector switch on the front of the unit to fill "UP" or drain "DOWN". If the "UP" function is selected, the output relay is energized until the MAX electrode becomes wet. Then it is de-energized and not re-energized until the MIN electrode becomes dry. If the "DOWN" function is selected, the output relay is energized as soon as the MAX electrode becomes wet. It remains energized until the liquid level has dropped below the MIN electrode. The electrode inputs AL and AL energize/de-energize the correspopnding output relays RAL (-) and RAL (3-3). AL opens if contact RAL (-) is wet. AL closes if contact RAL (3-3) is wet. This way, two additional alarm outputs for exceeding or dropping below the normal level can be implemented in addition to the filling levels MAX and MIN.

71 Sensor interface relay CM-SIS Ordering details SVR F300 CM-SIS The CM-SIS is used to supply - or 3-wire NPN or PNP sensors with power and to evaluate their switching signals. Two sensors of the types NPN or PNP can be connected simultaneously. Selection is done via the front-face rotary switch. The CM-SIS (terminals L+, L-) supplies the connected sensors with voltage (4 V DC), the maximum power supply current is 0.5 A. The and the sensor inputs are electrically isolated from the supply circuit. To ensure maximum safety when using these sensors, the principle of safe isolation has been included. Each sensor input signal energizes the corresponding output relay without delay. The relay is energized as soon as a threshold current is exceeded at input I or I. Sensor leakage currents of up to 8 ma don't affect the evaluation. The threshold value is about 9 ma. If the threshold value at input I or I is exceeded the corresponding relay R or R energizes and the corresponding LED lights up. The wide-range input of CM-SIS allows its application in nearly all supply systems. The CM-SIS is also suitable for other applications, for example it is also possible to connect PTC or NTC resistors instead of PNP or NPN sensors or to operate the SIS directly by switching contacts.

76 Cycle monitoring relay with watchdog function CM-WDS Ordering details CDC 5 00 F0004 CM-WDS The cycle monitoring relay CM-WDS (watchdog) observes if a regularly intermittent pulse is applied to its pulse input I. It is, for example, possible to connect the output of a programmable logic controller (plc), which is set and reset regularly (e. g. once each cycle). The connected cycle pulse must be generated by suitable programming of the plc/ipc. Now, the CM-WDS monitors if the cycle time of the plc/ipc program is smaller than the cycle monitoring time setted by means of the front-face selector switch time value (ms). The output relay -/4 of the CM-WDS energizes and the red LED is switched off, if there are minimum 8 successive regular pulses on input I. When the pulse signal stays out or is not regular, the output relay de-energizes and the red LED is illuminated. In case the monitoring time is too short or too long, this can be adjusted by a modified programming of the plc/ips or by modified setting of the monitoring time time value (ms). A fault recognized and stored with the CM-WDS can be reset by an H-impulse (0--transition) on the reset input R(9), so that the cycle monitoring is again released. The reset impulse can be generated by means of a reset button or by suitable programming of the controller (plc/ipc).
