interfaceinterfaceMeasuring and monitoring relays General information

The following statements apply to all devices, unless

contradirected by the information contained in the device’s

specific technical data sheet.

Standards

The devices meet the current standards and regulations:“Measuring relays and protective facilities” EN 60255-6:1994

“Thermal protection for rotating electrical machines” EN 60947-8:2003

“Low-voltage switching devices” EN 60947-5-1:2004

“Insulation monitoring devices for monitoring of AC networksthrough a superimposed DC voltage” VDE 0413-2:1973 DIN EN 61557-2:1998

“Equipping of power systems with electronic devices” EN 50178:1997

Rated voltage UN

The voltage type is represented by the indication AC, DC orAC/DC of the relevant rated voltage.

V AC

These devices are designed for operation under AC voltage. The corresponding rated frequency is indicated.

V DC

These devices are designed for operation under DC voltage. We have indicated either the permissible amplitude and themaximum value of the voltage characteristic of thesuperimposed AC voltage according to DIN 41755-1 or the ratedfrequency. Devices for which a rated frequency has beenindicated, can also be operated at an unfiltered voltage from abridge rectification (no half-wave rectification). In this case theoperating voltage is the root-mean-square value of the voltage.

Ud = arithmetic mean valueuuess = amplitude (peak-to-peak displacement)û = absolute maximum value of the voltage characteristic = umax

AC/DC

These devices are designed for operation under AC and DC voltage.They can be operated with an unfiltered voltage from a bridgerectification (no half-wave rectification). The operating voltage is theroot-mean-square value of the voltage.

Operating voltage range

If the rated voltage is indicated as a range, for example 110 to 127 Vand a permissible operating range between 0.8 and 1.1 x UN, theoperating range will extend from 0.8 x 110 V to 1.1 x 127 V.

Rated frequency

The devices can be operated within the indicated range, forexample 50 to 60 Hz, without any restrictions. When 50 to 60 Hzis indicated, the devices have a frequency selector. When 50 or60 Hz is indicated, the devices are designed for the relevantfrequency.

Operating range

0.95 to 1.05 x rated frequency. When a rated frequency range isindicated, for example 50 to 60 Hz, the permissible operatingrange is 0.95 x 50 Hz to 1.05 x 60 Hz.

Rated consumption

Devices that are designed for operation with AC voltage arespecified in VA and W corresponding to the rated frequency. Ifseveral rated frequencies are indicated, or a range, the indicationwill always refer to 50 Hz. For devices designed for operationwith DC voltage, the values are indicated for a DC voltagewithout superimposition. For devices designed for operationunder AC and DC voltage, the same values are indicated as forAC devices. When the consumption changes during thefunctional sequence, the highest value is always indicated. If thedevice‘s consumption can be higher for a short period of time, forexample at power ON (DC system, economy connection), itsvalue will be indicated additionally. Due to capacitors in thepower supply, an increased switch-on peak occurs in electronicdevices.

Release value

When the devices are operated through inductive proximityswitches in 2-wire designs or through long lines in case of ACvoltage, a residual voltage is still applied to the devices, althoughthe excitation voltage has been switched off. For properfunctioning of the devices this voltage must be lower than therelease value. LEDs for function indications may burn weakly incase of a residual voltage.


interfaceMeasuring and monitoring relays General information

Half-wave rectification

Various devices are equipped with an internal half-waverectification. As the devices must be adjusted for operation with2-wire inductive proximity switches, their half-wave rectificationvalue is indicated in the key data.

Inductive proximity switches in 2-wire design

Inductive proximity switches are subject to specified values forthe residual current that is allowed to flow over the load whenthe switch is disabled. These maximum values contradict therequirement for power consumption of the triggered contactorsand relays to be as low as possible. The market offers inductiveproximity switches with far lower residual currents. In order toadjust them to the required data of the switches, a field devicecan be added parallel to the load (mandatory for field deviceswith integrated half-wave rectification). Not all relays can beoperated parallel to the control input, pulse input or zero inputwith an additional load. A corresponding indication is made foreach device under “Technical data”.

Ambient temperature

Degree of protection

In accordance with EN 60529:2000. The protection degree forhousing and connections can be found in the housing data in thissection.

Recovery time

For proper functioning of the device, the value must not fallbelow the specified value. See the function diagram for additionalinformation. This value does not imply that an interruption ispermissible.

Mean value of the fault

Deviation of the arithmetic mean value of all the measured valuesfrom the pre-selected value.

Analog setting

The indications relate to end value of the range.

Fixed values

The indications relate to the rated value.

Dispersion

Dispersion means the difference between the smallestmeasured value and the largest measured value at a certainsetting and constant setting variable values. The indications forthe devices relate to the pre-selected time value.

Influence of the supply voltage

If an additional error is caused by changing the supply voltage,this influence is indicated in % for each % of change to thesupply voltage. The rated value is the reference point. Thisindication refers to the entire operating range.

Influence of the ambient temperature

If an additional error is caused by changing the ambienttemperature, this influence is indicated in % for each K oftemperature change. The reference point is + 20 °C. Thisindication refers to the entire operating range.

Fault influence

If an influence occurs that exceeds the standard value, it must beindicated accordingly.

Digital

Never set all the selector switches to zero. The position of theselector switches should not be changed during the functionalsequence, as otherwise this may cause functional faults.

Contact material

The contact material is indicated in “Technical data”. So far,there is no known contact material that would be perfect for thevariety of application options. The major characteristics of themost important contact materials are listed in the following.

Hard silver

Ag Cu has good conductivity, a high resistance to corrosion and alow welding tendency. It is suitable for medium to high switchingcapacities. An especially sulfurous atmosphere facilitates theoxidation that may cause contact interruptions. Ag Cu is notsuitable for switching voltages < 6 V.

Silver-cadmium oxide

(Variations indicated with letter W) Ag Cd O contacts have alower welding tendency, a higher resistance to corrosion and abetter arc extinction than Ag Cu contacts. Therefore they areespecially well suited for switching inductive and capacitiveloads. Its oxidation resistance is higher than that of Ag Cu. Ag Cd O is not suitable for switching voltages < 12 V.

Silver nickel

Ag Ni, an important material for inductive loads (6 – 380 V). Suitable for switch-on current between 10 mA and 100 A. Thecontacts have good resistance to corrosion, a low weldingtendency and higher contact resistances than Ag contacts.

Silver alloy, gold-plated

Silver alloys with a high resistance to corrosion (Ag Ni, Ag Sn O2)are used underneath the gold plating, so that the same life spanas with Ag Ni, Ag Cd O or Ag Sn O2 can be expected after thegold plating is permeated through higher or inductive loads. Lowvoltages and currents are safely switched with gold plating.Please ensure that the gold layer, if required, is not destroyed byimproper use prior to the contact’s intended use.

The permissible switching voltage Un (see “Technical data”)must be adhered to.

Terminal markings and position of the terminals

All devices designed for operation under DC voltage areprotected against destruction in case of incorrect wiring. If thisprotection is designed as bridge rectification, the device will workproperly even in the case of incorrect poling. In this case, thecircuit diagram of the corresponding device‘s will not show anypolarity. If the poling protection is designed as half-waverectification, the device will not work in the case of incorrectpoling. For an optimal interference suppression of device‘sdesigned for AC voltage, terminal A1 should be assigned to L1and terminal A2 to N. When a control-power transformer is used,terminal A2 should always be assigned to the line common for allload bearing devices. In the circuit diagrams in the catalog, theposition of the terminals corresponds to the assignment on thedevice.

EC directives and declaration of conformity

This general technical information applies for all the devices thatmay be covered by one or more of the following EC directives:

EC Machine Directive 98/37/EGEC EMC Directive 89/336/EWGEC Low-Voltage Directive 73/23/EWG

The conformity of the devices that meet the requirements of thecorresponding EC directive is indicated by the CE mark ofconformity on the type plate. Information about which directivesand standards are met by the devices is provided by the ECDeclaration of Conformity. If the devices identified as such do notmeet all the directives during the directive’s transition period, thiswill be mentioned in the documents that accompany the device.The devices without the EC mark of conformity meet therespective standards indicated. This indication functions asdeclaration of conformity in the sense of article 10 of the ECLow-Voltage Directive 73/23. The devices that were put on themarket after 1995-12-31 must meet the requirements of theEMC Directive. In case of replacement devices that cannot beoperated on their own and do not carry the CE mark, the userhimself is responsible for the proper installation according to § 5 sec. 5 EMVG and for the fulfillment of the protectionrequirements according to § 4 sec. 1 EMVG. Wieland ElectricGmbH will provide users with the EC declarations of conformityon request.

Safety instructions

Installation, start-up, modification and retrofit of all devices mustbe performed by a qualified electrician only! Disconnect thedevice/system from the load prior to starting any work! Followthe safety instructions of electrical engineering and the tradeassociation! Negligence of the safety instructions may causedeath, grievous bodily harm or severe material damage!

We reserve the right to make technical changes that result intechnological advance.


Voltage measuring relay

• For monitoring the upper and lower limit values of single phase voltages• 3 measuring ranges from AC/DC 0.5 to 500 V• Sinusoidal, square, delta waveforms• 16 ON-delay times selectable: no delay, 0.1 s to 3 h• Frequency range of the measuring variable between 45 and 400 Hz• Multi-functional: Open-circuit or closed-circuit principle; hysteresis 3 % or

10 % from the setpoint

Applications

• Monitoring of voltage levels• Monitoring of interference voltage in networks with external power supply• Monitoring of field excitation of motors• Monitoring of frequency drives• Monitoring of analog correcting variables

Functions

The NMU 1001 is a monitoring relay with three measuring ranges for single-phasevoltages between AC/DC 0.5 V and AC/DC 500 V. The frequency range covers 45 Hzto 400 Hz at AC. The measured value is recorded with an integrated full wave rectifier.Therefore it is possible to monitor non-sinusoidal currents or voltages (e.g. voltageswith harmonic component). With AC, the devices evaluate the rectifier value calibratedon the root-mean-square of a sine voltage. With DC measuring values, a rectification isperformed and the mean value is monitored. The effective value itself is notmonitored. As output contact, 1 change-over contact is available. There is an electricalisolation between the auxiliary supply, the measuring circuit and the output circuit(relay contact).

The three measuring ranges are adjusted through the different connections of theinput terminals B1, B2, B3 and B4. The response value is adjusted with thepotentiometer Vx. The device functions and the ON-delay time are adjusted by usingthe rotary switches (see “Settings”).

Function of the open-circuit principle

After applying the supply voltage and transgression of the lower limit (<) or upper limit(>) values of the pre-selected response value, the output relay switches into the ONposition. This occurs according to the pre-selected ON-delay time. When themonitoring variable returns to the response value, the output relay switches into theOFF position depending on the adjustment of the hysteresis ( 3 % or 10 %).

Function of the closed-circuit principle

After applying the supply voltage and after the standby time tB, the output relayswitches into the ON position. The transgression of the lower limit (<) or upper limit(>) of the pre-selected response value, according to the selected function, causes theoutput relay to switch back into the OFF position depending on the pre-selected ON-delay time. When the monitoring variable returns to the response value, theoutput relay switches into the ON position depending on the adjustment of thehysteresis (3 % or 10 %).

Notes

• Operation of the function switch or the time switch during the timing period willimmediately terminate the timing operation.

• With the delay “–” (no delay) and with simultaneous active function (of the responsevalue), the NMU 1001 will respond to the instantaneous value of the monitoringvariable at a certain threshold and cause the output relay to switch into “quick time”(see “Response time” under “Technical data”).

• Disconnect the connection cables of the voltage measuring relay prior to performingan insulation or voltage test.

Setting example:

Setpoint (response value) AC/DC 4 V ON-delay time withoutFunction underflow, closed-circuit principle, 10 % hysteresis

Settings:• Measuring range AC/DC 0.55 to 5 V (terminals B1 and B2)• Potentiometer Vx set to 0.8 (0.8 x measuring range end value 5 V) = 4 V

(response value)• Rotary switch ON-DELAY set to “–”• Function rotary switch set to > 10

If the measured value falls below the response value of 4 V, the output relay will switchinto the OFF position without an ON-delay time, and the LED TRIPPED will light. If the actual monitoring value exceeds the response value plus the hysteresis of 10 %,the output relay will switch into the ON position. The LED TRIPPED will extinguish (seeFunction diagram).

Application examples

Setting example:

Setpoint (response value) AC/DC 25 V ON-delay time 100 sFunction overrange, open-circuit principle, 3 % hysteresis

Settings: • Measuring range AC/DC 5 to 50 V (terminals B1 and B3)• Poti Vx set to 0.5 (0.5 x measuring range end value 50 V) = 25 V (response value)• Rotary switch ON-DELAY set to 100 s• Function rotary switch set to > 3

If the monitoring value exceeds the response value of 25 V, the LED TRIPPED will beginto flash. After the pre-selected ON-delay time of 100 s, the output relay switches intothe ON position and the LED TRIPPED burns continuously. If the actual monitoringvalue falls below the response value minus the hysteresis of 3 %, the output relay willswitch back into its OFF position. If it falls below the response value before the pre-selected ON-delay time is reached, the LED TRIPPED will extinguish (see the Functiondiagram).

Functions

The voltage measuring relay SUM 1001 is a monitoring relay for single-phase voltages.The measured value is fed in through different terminals (see table I) according to thedesired measuring range. With the setpoint potentiometer, the response value can beadjusted analogically within the pre-selected measuring range. The on-time delay can beadjusted with the time range switch and the time setpoint potentiometer (see table II).


After applying the supply voltage and transgression of the lower or upper limit values(depending on the selected function – see table III) of the pre-selected response value,the output relay switches into the ON position. This occurs either according to the pre-selected ON-delay time or immediately. The transgression of the limit values(underflow or overrange) of the response value, according to the selected function, byat least 3 % or 10 % (hysteresis) causes the output relay to switch back into the OFFposition.


After applying the supply voltage, the relay switches into the ON position after tB. Thetransgression of the lower or upper pre-selected limit values, according to the selectedfunction, causes the output relay to switch back into the OFF position depending onthe pre-selected ON-delay time. Depending on the pre-selected hysteresis (3 % or 10 %), the output relay switches back into the ON position after the correspondingtransgression of the lower or upper response value.

Notes

• The power supply is electrically isolated from the measuring circuit and isdisplayed by LED SUPPLY.

• The measured value is recorded with an integrated full wave rectifier. Thereforeit is possible to monitor non-sinusoidal voltages (e.g. voltages with harmonic,square or delta voltages ranging between 45 and 400 Hz).

• With AC, the devices evaluate the rectifier value calibrated on the root-mean-square of a sine voltage.

• With DC measuring values, a rectification is performed and the mean value ismonitored.

• With NO DELAY and simultaneous active function overrange (> V), themonitoring relays will respond to the instantaneous value of the monitoringvariable at a certain threshold and cause the output relay to switch into “quicktime” (see Technical Data).

• Disconnect the connection cables of the voltage measuring relay prior toperforming an insulation or voltage test.

If theactual measured value exceeds the setpoint plus the hysteresis of 10 %, the outputrelay will switch into the ON position. The LED TRIPPED will extinguish (see Functiondiagram 4).

If the actual measured value fallsbelow the setpoint minus the hysteresis of 3 %, the output relay will switch back into itsOFF position. If it falls below the measured value before the pre-selected ON-delay timeis reached, the LED TRIPPED will extinguish (see Function diagram 1).

Applications

Functions

The NMI 1001 is a monitoring relay for single-phase currents. There are two typeswith different measuring ranges. The frequency range covers 45 Hz to 400 Hz at AC.The measured value is recorded with an integrated full wave rectifier. Therefore it ispossible to monitor non-sinusoidal currents (e.g. currents with harmonic component).With AC, the devices evaluate the rectifier value calibrated on the root-mean-square ofa sine voltage. With DC measuring values, a rectification is performed and the mean value ismonitored. The effective value itself is not monitored. As output contact, 1 change-over contact is available. There is an electrical isolation between the auxiliary supply,the measuring circuit and the output circuit (relay contact).

The three measuring ranges are adjusted through the different connections of theinput terminals B1, B2, B3 and B4. The response value is adjusted with thepotentiometer Ix. The device functions and the ON-delay time are adjusted by usingthe rotary switches (see “Settings”).


After applying the supply voltage and transgression of the lower limit (<) or upper limit(>) values of the pre-selected response value, the output relay switches into the ONposition. This occurs according to the pre-selected ON-delay time. When themonitoring variable returns to the response value, the output relay switches into theOFF position depending on the adjustment of the hysteresis ( 3 % or 10 %).


After applying the supply voltage and after the standby time tB, the output relayswitches into the ON position. The transgression of the lower limit (<) or upper limit(>) of the pre-selected response value, according to the selected function, causes theoutput relay to switch back into the OFF position depending on the pre-selected ON-delay time. When the monitoring variable returns to the response value, the outputrelay switches into the ON position depending on adjustment of the hysteresis (3 % or 10 %).

Notes

• Operation of the function switch or the time switch during the timing period willimmediately terminate the timing operation.

• With the delay “–” (no delay) and simultaneous active function overflow (of theresponse value), the NMI 1001 will respond to the instantaneous value of themonitoring variable at a certain threshold and cause the output relay to switch into“quick time” (see the ‘Response time’ under Technical Data).

• Disconnect the connection cables of the current measuring relay prior to performingan insulation or voltage test.

If the monitoring value falls below the setpoint of 12 A, the output relay will switch intothe OFF position without an ON-delay time, and the LED TRIPPED will light. If the actual monitoring value exceeds the response value plus the hysteresis of 10 %,the output relay will switch into the ON position. The LED TRIPPED will extinguish (see Function diagram).

If the monitoring value exceeds the setpoint of 50 mA, the LED TRIPPED will begin toflash. After the pre-selected ON-delay time of 100s, the output relay switches into theON position and the LED TRIPPED burns continuously. If the actual monitoring valuefalls below the response value minus the hysteresis of 3 %, the output relay will switchback into the OFF position. If it falls below the response value before the pre-selectedON-delay time is reached, the LED TRIPPED will extinguish (see the Function diagram).

With the setpoint potentiometer, the response value can beadjusted analogically within the pre-selected measuring range.

This occurs either according to the pre-selected ON-delay time or immediately. The transgression of the limit values(underflow or overrange) of the response value, according to the selected function, byat least 3 % or 10 % (hysteresis) causes the output relay to switch back into the OFFposition.


After applying the supply voltage, the relay switches into the ON position after tB.

Voltage or current measuring relay

• For monitoring the upper and lower limit values of single phase voltages• Response value selectable in a 1:10 ratio• Release value adjustable from to 50 to 95 % of the response value• With auxiliary voltage• SXT 12: Open-circuit principle

SXT 32: Closed-circuit principle

Applications

• Monitoring of field excitation of motors• Monitoring of interference voltage in networks with external power supply• Monitoring of overvoltage levels• Monitoring of overcurrent levels

Function

The measuring relay is connected to a permanent supply voltage of 50 to 60 Hz. Thecurrent or voltage to be monitored is supplied via terminals B1/B2. The supply voltagecircuit and the measuring circuit are electrically isolated by means of a transformer. A response value and a release value are set on the relay. If the measured valueexceeds the response value, the relay will switch. If the measured value falls belowthe release value, the relay will fall back into its initial position. The release value is adjustable within the range between 0.5 and 0.95 of the response value.

SXT 12 – open-circuit principle

When supply voltage is applied, the SXT 12 is in OFF position. If the response value is exceeded, it will switch into the ON position. If it falls below the release value, the relay will switch back into the OFF position.

SXT 32 – closed-circuit principle

When supply voltage is applied, the SXT 32 switches into the ON position. If theresponse value is exceeded, it will switch back into the OFF position. If it falls below the release value, the relay will switch back into the ON position.

Notes

• Unfiltered or partially filtered DC voltages and currents can also be monitored in themeasuring circuit. It should be observed that the relay responds to the positive peakvalues, but is adjusted to the corresponding root-mean-square values at 50 Hz.

• Negative currents are not measured but also not influenced (same operating range as for the positive currents).

Application examples RPM monitoring

The rpm delivered by the tachogenerator is transformed into a voltage measurement. This voltage (measured value) is monitored by the SXT 32 measuring relay. If thevoltage exceeds the pre-selected response value, the relay will switch into the OFFposition (closed-circuit principle). The fault will be indicated by lamp H1. The flow can be controlled by the PLC.

Response time

The response time is the time intervalbetween the occurrence of a measuredvalue and the change-over of the relay. It isinfluenced by the factor by which themeasured value exceeds the responsevalue. The permissible interference pulsewidth is the duration of an interferencepulse at which the relay does not yetrespond.

Current monitoring for the load

If the current in the load (measured value) exceeds the pre-selected response value,the relay switches into the OFF position (closed-circuit principle). The fault will beindicated by lamp H1. If the current falls below the release value, the relay will switchback into the operating position.

Applications

• Monitoring the supply voltage of installations such as:• Crane and elevator systems• Machines with reversal of rotational direction• Pumps, condensers or compressor systems• Air conditioning and ventilation systems• Distribution stations• Escalators

Function

The SAM 1001 monitors the external line voltages L1, L2, L3. It monitors:• whether three-phase voltages are applied• the phase sequence• the balanceIf the parameters are faultless, the SAM 1001 will switch into its ON position. If one ofthe conditions is not fulfilled, the relay will remain in its OFF position. The red LEDlights up. It is reset automatically after the fault has been eliminated.If a phase failure occurs during operation, this will be recognized even when a voltagefeedback occurs through a connected field device. The relay falls back into its OFFposition and the red LED lights up. An imbalance limit value can be set on the relay.A response time and release time of 1000 ms each is permanently set internally.

Applications

• Monitoring of three-phase current network fault on machines or systems, such as:• Processing machines, palletizing systems, packaging machines• Machines with reversal of rotational direction• Escalators and elevator systems• Pumps and compressors• Air conditioning and ventilation systems

Function

The SPW devices monitor their external line voltages (their own three-phase power supply) L1, L2, L3 for:• Phase sequence in clockwise rotation• Phase failure• Phase voltage imbalance• Phase shift• Undervoltage

After applying the external line voltages L1, L2, L3 and with correct three-phasecurrent parameters, the SPW switches into the ON position (closed-circuit principle).The green LED lights up. If one of the above mentioned conditions is not fulfilled, therelay will remain in or switch into its OFF position. The SPW operates without auxiliarysupply voltage and neutral connection. The rated voltage for the three-phase currentnetworks can be pre-selected in 3 ranges – 3 AC 380 V, 400 V, 415 V – analog with apotentiometer on the front of the device. If a fault occurs, the relay will switch into itsOFF position with a reaction time of 35 ms. The green LED will extinguish. After thefault has been removed, the SPW automatically switches into its ON position and theLED lights up.

Fault detection occurs at:• Incorrect phase sequence• Phase failure of 100%, such as wire breakage in the lines leading to the device• Phase failure even at back-voltage up to 85%• Undervoltage detection up to 20% of one, two or all three phases, related to the

adjusted voltage of 3 AC 380 V, 400 V, 415 V• Phase voltage imbalance above 15%• Phase shift of one phase compared to the other phases

The two devices differ in their contact assignments. The SPW 1004 is fitted with twochange-over contacts, while the SPW 1005 is fitted with one change-over contact.

Three-phase – phase sequence relays without auxiliary

supply voltage

• Detection of incorrect phase sequence• Closed-circuit principle• Contact assignment: SAP 1002 1 change-over contact, SAP 1003

2 change-over contacts

Applications

• Monitoring of the phase sequence in systems such as:• Crane and elevator systems• Machines with reversal of rotational direction • Pumps, condensers and compressors• Air conditioning and ventilation systems• Detection of the direction of motion of escalators

Function

The SAP devices monitor their correct phase sequence after phases L1, L2, L3 havebeen applied (clockwise rotation). With a pure ohmic load, a phase failure is alsodetected.

After applying the external line voltages L1, L2 L3 and if the phase sequence iscorrect, the relay will switch into the ON position. If one of the conditions is notfulfilled, the relay will remain in the OFF position. The red LED lights up.

If a phase failure occurs during operation, the relay will switch back into the OFFposition (the red LED lights up), if no voltage feedback occurs through the connectedloads. It is reset automatically after the fault has been eliminated.

The two devices differ in their contact assignments.The SAP 1002 is fitted with one change-over contact, while the SAP 1003 is fitted withtwo change-over contacts.

• Monitoring of three-phase current – undervoltage faults and phase failureof machines or systems, such as:- Machines with reversal of the direction of rotation (cranes, robots, pumps,excavators, conveyor systems, etc.)

- Chemical processes- Test and calibration systems

Three-phase voltage monitor without auxiliary supply voltage

• Undervoltage detection of one, two or all three phases• Adjustable undervoltage detection between 285 and 360 V• Detection of phase failure of one, two or all three phases• Rated three phase voltage 3 AC 400 V without neutral connection and

auxiliary supply voltage• Reaction time 35 ms• Closed-circuit principle• Contact assignment: 2 change-over contacts

Function

The SUW 3001 monitors the external line voltages (its own voltage supply) L1, L2, L3for undervoltage and phase failure. It works without a neutral connection and an auxiliary supply voltage.

After applying the external line voltages L1, L2, L3, the voltages of which exceed thevoltage limit value, the SUW switches into its ON position (closed-circuit principle).The green LED lights up. If the voltage falls below the pre-selected voltage limit value,the relay will switch into its OFF position. The green LED extinguishes.

The rated voltage for three-phase current networks is 3 AC 400 V with a largeoperating voltage range. The setpoint value of the undervoltage can be pre-selected tobetween 285 and 360 V with a potentiometer. If a fault occurs, the relay will switchinto its OFF position with a reaction time of 35 ms. The green LED will extinguishes.After elimination of the fault, the SUW switches automatically into its ON position andthe pre-selected 10 V hysteresis applies. The green LED lights up.

Fault detection occurs at:• Phase failure of one, two or all three phases• Undervoltage detection of one, two or all three phases, related to the adjusted

voltage of 3 AC 285 V to 360 V

Functions

SBW 1004 – open-circuit principle

When the motor is switched on, the adjustable start-up override time on the relaybegins. After this time has elapsed, the SBW 1004 monitors the pre-selected phaseshift cos ϕ (in °). When the load falls, the phase shift becomes larger – cos ϕ becomes smaller. If the pre-selected phase shift is exceeded, the relay willswitch into its ON position after expiration of the pre-selected response time. If thephase shift falls below the pre-selected value – back to a normal load – the relay willswitch into OFF position after expiration of the pre-selected release time. The pre-selected response and release times (1000 ms) prevent the relay from respondingduring brief deviations from the setpoint value.

SBW 1005 – closed-circuit principle

When supply voltage is applied, the relay switches into the ON position.When the motor is switched on, the adjustable start-up override time on the relaybegins. After this time has elapsed, the SBW 1005 monitors the pre-selected phaseshift cos ϕ (in °). When the load falls, the phase shift increases – cos ϕ decreases. Ifthe pre-selected phase shift is exceeded, the relay will switch into its OFF positionafter expiration of the pre-selected response time. If the phase shift falls below thepre-selected value – back to a normal load – the relay will switch into the ON positionafter expiration of the pre-selected release time. The pre-selected response andrelease times (1000 ms) prevent the relay from responding during brief deviationsfrom the setpoint value.

SBW 1004/SBW 1005 – with fault memory

The fault memory is put into operation by shunting the terminals Y1, Y2. If the phaseshift falls below the pre-selected value – back to normal load – the relay will remain inthe ON/OFF position. The fault memory is cleared only by being reset; the relayswitches into the OFF/ON position. If the pre-selected phase shift is still exceeded,the relay will switch into the OFF/ON position only during the resetting.

The load monitor SBW 1004 controls the conveyance quantity. If too little material issupplied – falling load – the relay will switch into its ON position after expiration of thepre-selected response time.

Monitoring dust filters

The load monitor SBW 1005 monitors the filter for contamination. If the filter iscontaminated, the motor load falls – cos ϕ becomes smaller. If the pre-selected phaseshift is exceeded, the relay will switch into its OFF position after expiration of the pre-selected response time – closed-circuit principle. The fault is stored until the reset keyis operated manually.

Function diagrams

Principle

With an inductive load, the current lags behind the voltage by phase angle ϕ. If the load on the motor falls, the phase angle becomes larger and subsequently cos ϕbecomes smaller. This change of phase angle is a precise measure of the load changeat the motor shaft. The load monitor monitors the phase shift between the voltageand the current under inductive loads in a sinusoidal single-phase and three-phasenetwork. (Not suitable for phase control and frequency-controlled motors).

Functions of the closed-circuit principle

When supply voltage is applied, the relay switches into the ON position.When the motor is switched on, the adjustable start-up override time on the relaybegins. After this time has elapsed, the SBW 1007 monitors the pre-selected phaseshift cos ϕ (in °). When the load falls, the phase shift becomes smaller – cos ϕbecomes larger.

Monitoring of rolls

The load monitor SBW 1007 monitors the roll contact pressure. If the roll contactpressure rises, the motor load also rises (cos ϕ becomes larger). If the phase shift fallsbelow the pre-selected value, the relay will switch into its OFF position (closed-circuitprinciple).

After applying the supply voltage (A1/A2) and connection of the PTC thermistor (T1/T2), the relay switches into the ON position. It operates accordingto the closed-circuit principle and ensures safe switch-back into the OFFposition in case of the following malfunctions:• Due to the increasing temperature, the PTC thermistor exceeds a resistance value in

the range ≥ 2500 Ω to ≤ 3600 Ω (when the temperature decreases and the PTCthermistor’s resistance value ranges between ≤ 1500 Ω and ≥ 1000 Ω, the relay willswitch back into the ON position)

• The sensor circuit falls below a resistance value of < 20 Ω in case of short circuit• Damage to the cables• Power failureThe fault is indicated when the LED TRIPPED lights up. The fault is not stored.SMS 1005

The basic function corresponds to that of the SMS 1002. An additional fault memoryprevents the relay from switching back into the ON position after elimination of thefault. The fault memory can be cleared by operating the reset key only if the fault hasbeen eliminated. The SMS 1005 will be ready for another fault identification only if thefault memory has been cleared or the supply voltage has been switched off for at least250 ms.

Monitoring of oil temperature

If the oil temperature in the transformer rises above the rated operating temperature(TNF), the relay will switch into the OFF position. The horn H1 signals the overheating.Temperature adjustments can be fed through the PLC. The fault memory of the SMS1005 prevents the relay from switching back into the ON position after the fault hasbeen eliminated. The fault memory can only be cleared after the reset key is pressedor the supply voltage is switched off for at least 250 ms.

Switching range / Resistance curve

Sensor

PTC thermistors (temperature sensors) are resistances with very high positiveresistance temperature coefficients. (PTC = positive temperature coefficient). Theyare installed in the outlet air side of the stator end winding of those motors for whichthe temperature diagram is known prior to manufacturing. Their rated operatingtemperature (TNF) depends on the motor type. When the rated operating temperatureis exceeded, the resistance value of the PTC thermistors will increase abruptly. If thissensor is connected to a motor protection relay/temperature monitor, the abruptincrease in the resistance value will cause the relay to switch.


Motor monitoring

If the motor temperature exceeds the rated operating temperature (TNF) of thePTC thermistor temperature sensor, or if cable damage/short circuit occurson the sensor, the motor is switched off via K1.

Three types of connections are normally usedfor Pt 100 temperature sensors. Thetemperature monitors STW 1101 and STW1102 are connected according to the 3-wiretechnology (principle diagram). The constantcurrent IK will then flow through thetemperature sensor. In order to halve themeasurement errors through the lineresistances RL1 and RL2, a third conductor isused as a measuring conductor. Theresistance of the measuring conductor RLMcan be disregarded due to the high internalresistance of the temperature monitor.

NiCr-Ni temperature sensor

NiCr-Ni sensor according to DIN 43710 IEC 584 sec. 1 type K

The temperature difference between the measuring point and the reference junctiongenerates a thermal voltage between the two elements. This is evaluated by theSTW. The equalizing conductors are used as an extension of the thermocouples(principle diagram). They are installed from the connection of the thermocouple to thereference junction (equalizing box, measuring point selector).

The equalizing conductors consist of a positive and a negative conductor. They havethe same thermoelectrical properties as the thermocouple up to +200 °C. For thisreason, no thermal voltages occur at the connection points. The highest temperaturefor the equalizing conductors is + 200 °C, regardless of the insulation material used. Ifthe temperature at the connection point is higher, a thermal conductor must be usedinstead of an equalizing conductor in order to achieve greater measurement accuracy.Equalizing conductors are less expensive than thermal conductors. Normally theyhave a larger cross section and a lower electrical resistance. From the economic pointof view they are better suited for long lines.

Contact protection relay

• Supply voltage and control circuit electrically isolated• ON-delay and OFF-delay times adjustable between 0.05 and 1 s• Contact assignment:

SST 12: 2 change-over contactsKST 12: 1 normally open, 1 normally closed

Applications

• Protection of sensitive switching contacts such as measuring instruments,manometers pressure monitors

• Avoidance of contact bouncing• As timer relay for short times (ON-delay and OFF-delay times)• As level monitor in connection with float switches

Function

SST 12

The contact protection relay is constantly connected to a supply voltage. The supplyvoltage circuit and the control circuit are electrically isolated by means of atransformer.

If the control circuit is closed (for example by exceeding the limit value in a contactmanometer), the relay will switch into the ON position when the pre-selected ON-delay time has elapsed.When the control contact is opened, it will switch back into the OFF position afterelapse of the OFF-delay time. The ON-delay time and the OFF-delay time are identical.

The open control contact is supplied with a voltage ≤ 11 V DC. A current ≤ 2 mA DCflows over the closed control contact. This way, the control contact is not overloaded.

Contact assignment: 2 change-over contacts

KST 12

It functions just like the SST 12, however the number of contacts are 1 NO, 1 NC.

Notes

• On contact manometers, a control contact indicates the exceeding of the pre-selected limit value. The contact should not impede the movement of the pointer. In order to fulfill this condition, very small control contacts are used. They support amaximum load of 25 mW.With higher loads the contacts would be destroyed.

• A correct function is guaranteed if the total ohmic value of lines and contactresistances does not exceed 500 Ω.
