Motor Protection and MonitoringMonitoring Relays42.1ECS Series CurrentWatch Current SwitchesECS Series CurrentWatch Current SwitchesECS SeriesProduct DescriptionThe CurrentWatch ECSSeries from Eaton’s electricalsector is a family of solidstateadjustable currentswitches, ideal for providingstatus information onelectrical equipment. TheECS is excellent for newinstallations, where theconductors run through thehousing, requiring no cutting.These switches are also idealfor retrofits, since split-coremodels can be opened to fitaround existing conductors.The current switch isaccurate, reliable and easyto install.The ECS can sensecontinuous currents from1 to 150A and does notrequire any supply voltage,as the power required isinduced from the monitoredconductor. The output is anon-polarity-sensitive solidstatecontact for switchingAC and DC circuits up to240 Vac/Vdc. This switch alsoincludes an LED indicatingtwo states: on and below trippoint, and above trip pointwith contacts energized. AllECS Series switches carry anunconditional five-yearwarranty.ReferenceRefer to PG08301004E, Sensing Solutions Catalog,Tab 7, section 7.2 for additional Product information.ECS Series CurrentWatchTab SectionApplication Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7.2Product Selection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7.2Accessories . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7.2Technical Data and Specifications . . . . . . . . . . . . . . . . . . . . 7.2Wiring Diagrams . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7.2Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7.2ContentsDescriptionPageCurrent Monitoring RelaysECS Series CurrentWatch Current SwitchesECSJ Series CurrentWatch Current Switches . . . . . . . . 4D65 Current Monitoring Relays . . . . . . . . . . . . . . . . . . . 5Phase Monitoring Relays . . . . . . . . . . . . . . . . . . . . . . . . . . . 16Voltage Monitoring Relays . . . . . . . . . . . . . . . . . . . . . . . . . . 28Ground Fault Monitoring Relays . . . . . . . . . . . . . . . . . . . . . 42Any change in current can besensed with the ECS Series.A change in current mayindicate motor failure, beltloss/slippage or mechanicalfailure.

All D65 phasemonitoring relays arecompatible with most wyeor delta systems. In wyesystems, a connection toneutral is not required. PhaseMonitoring relays protectagainst single-phasingregardless of anyregenerative voltages.Application DescriptionProtectionDepending on the unitselected, it will protect threephaseequipment against:●●Phase Loss—total loss ofone or more of the threephases. Also known as“single phasing.” Typicallycaused by a blown fuse,broken wire or worn contact.This condition would result ina motor drawing locked rotorcurrent during startup. Inaddition, a three-phasemotor will continue to runafter losing a phase,resulting in possible motorburn-out.Phase Reversal—reversingany two of the three phaseswill cause a three-phasemotor to run in the oppositedirection. This may causedamage to driven machineryor injury to personnel. Thecondition usually occurs as aresult of mistakes madeduring routine maintenanceor when modifications aremade to the circuit.●●●Phase Imbalance—imbalance of a three-phasesystem occurs whensingle-phase loads areconnected such that one ortwo of the lines (phases)carry more or less of theload. This could causemotors to run attemperatures abovepublished ratings.Undervoltage—whenvoltage in all three lines ofa three-phase system dropsimultaneously.Overvoltage—whenvoltage in all three lines ofa three-phase systemincrease simultaneously.4242424216 Control Products Catalog CA08102001E—September 2010 www.eaton.com

Phasemonitoring relays protectagainst voltage imbalance andsingle-phasing regardless ofany regenerative voltages.The relay is energized whenthe phase sequence and allvoltages are correct. Any offive abnormal conditions(phase loss, phase reversal,overvoltage, undervoltageor phase imbalance) willde-energize the relay. Asstandard, re-energizationis automatic upon correctionof the fault condition. TheD65 can also be wired formanual reset.Protective FunctionsThe D65 Series Relay makesseparate trip decisions basedon the status of the threephasevoltage inputs. Controlpower is derived from thethree-phase voltage inputs.Separate control power is notrequired. The device will tripin response to anycombination of the followingconditions:●Undervoltage—Whenvoltage in all three lines ofa three-phase systemdrops simultaneously.Undervoltage drop-out canbe set at 80–95% ofoperating voltage. Unittrips when the average ofall three lines is less thanthe adjusted set point for aperiod longer than theadjustable time delay dropout(0.1–20 seconds). Thistime delay eliminatesnuisance tripping causedby momentary voltagefluctuation.DescriptionPageCurrent Monitoring Relays . . . . . . . . . . . . . . . . . . . . . . . . . 3Phase Monitoring RelaysProduct Selection Guide . . . . . . . . . . . . . . . . . . . . . . . . 17D65VMC Series—Phase Reversal . . . . . . . . . . . . . . . . . 18D65PLR Series—Phase Loss and Reversal . . . . . . . . . . 20D65PAR Series—Phase Loss, Reversaland Undervoltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . 22D65VM Series—Phase Loss, Reversal, Imbalanceand Under/OvervoltageFeatures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25Product Selection . . . . . . . . . . . . . . . . . . . . . . . . . . . 26Technical Data and Specifications . . . . . . . . . . . . . . . 26Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27Voltage Monitoring Relays . . . . . . . . . . . . . . . . . . . . . . . . . 28Ground Fault Monitoring Relays . . . . . . . . . . . . . . . . . . . . . 42●●Overvoltage—Fixed at110% of nominal, unit tripswhen the average of allthree lines is greater thanthe fixed set point for aperiod longer than the timedelay drop-out.Phase Imbalance—Imbalance of a three-phasesystem occurs whensingle-phase loads areconnected such that one ortwo of the lines (phases)carry more or less of theload. This could causemotors to run attemperatures abovepublished ratings. Unit tripswhen any one of the threelines is more than theadjusted set point belowthe average of all threelines. The percent phaseimbalance is adjustablefrom 2–10% and also has aDisable setting forapplications where poorvoltage conditions couldcause nuisance tripping.●●Phase Loss (Single-Phasing)—Total loss ofone or more of the threephases. Typically causedby a blown fuse, brokenwire or worn contact. Thiscondition would result in amotor drawing locked rotorcurrent during start-up. Inaddition, a three-phasemotor will continue to runafter losing a phase,resulting in potential motorburn-out. Unit trips on lossof any phase.Phase Reversal—Reversing any two of thethree phases will cause athree-phase motor to run inthe opposite direction. Thismay cause damage tomachinery or injury topersonnel.

All versions areavailable in a compact plug-incase using an 8-pin octalsocket.There are two styles ofvoltage monitoring relays:●●Over/Undervoltage RelaysVoltage Band RelaysOver/Undervoltage RelaysOver/Undervoltage Relaysprovide protection toequipment where either anover- or undervoltagecondition is potentiallydamaging. Each relay can beused as either an overvoltageor an undervoltage relay,depending on the outputcontact used. When used asan undervoltage relay, itprovides protection toequipment that is required tooperate above a minimumvoltage. When used as anovervoltage relay, it protectsequipment against excessivevoltage conditions. Over/undervoltage relays aredesigned to operate whenthe operating voltage reachesa preset value and drop outwhen the operating voltagedrops to a level below thepreset value.Voltage Band RelaysVoltage Band Relays provideprotection to equipment thatis required to operate withinan upper and lower voltagelimit.

Motor Protection and MonitoringMonitoring Relays42.1D64L Series—Ground Fault MonitorsD64L Series—Ground Fault MonitorsProduct DescriptionType D64L ground faultmonitors are designed tomonitor ungrounded supplieson three-phase AC powersystems up to 600V. If aninsulation fault developsanywhere on the systembetween the source and theload, the D64L will detect itand give an alarm or trip,depending on the adjustablefield settings selected.The D64L is ideally suited forsystems supplied from thesecondary of either anungrounded delta or anungrounded wye connectedtransformer.Because D64L has highimmunity from the effects ofvoltage transients and cablecapacitance, it may beapplied in automotive, subsea,mobile lighting, portablegenerators, sensitiveequipment and otherinstallations whereungrounded systems areused extensively.The user is able to individuallyset the alarm level and thetrip level from 20%–80% ofthe maximum leakage currentlimit of the D64L selected.Any leakage current abovethe alarm level will activatethe alarm relay and light thealarm LED. Should theleakage current rise abovethe trip level, the trip relayand trip LED will activate.ContentsDescriptionPageCurrent Monitoring Relays . . . . . . . . . . . . . . . . . . . . . . . . . . 3Phase Monitoring Relays . . . . . . . . . . . . . . . . . . . . . . . . . . . 16Voltage Monitoring Relays . . . . . . . . . . . . . . . . . . . . . . . . . . 28Ground Fault Relays and MonitorsD64R Series—Digital Ground Fault Relays . . . . . . . . . . . 43D64L Series—Ground Fault MonitorsProduct Selection . . . . . . . . . . . . . . . . . . . . . . . . . . . 54Wiring Diagram. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 54Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 54Features● Adjustable leakage currentlimit setting (20 mA, 35mA or 50 mA).

Theyprovide an economical solutionfor applications requiringsimple manual starting andstopping of motors. Whenused as a manual starter, theyare typically installed in anenclosure. Many enclosuresare offered as accessories forthe MMPs. Separate shortcircuitprotective devices, suchas circuit breakers or fuses, arewired ahead of the MMPs. Theshort-circuit protective deviceshould be sized per the NECand should not exceed 400%of the maximum FLA dialsetting of the MMP.Individual Branch MotorApplicationsA UL 508 Type E selfprotectedmanualcombination starter/motorcontroller consists of a singledevice possessing fouressential elements:disconnect, short circuitprotection, motor controller,and motor overloadprotection. Some MMPsrequire use of a linesideadapter for this type ofapproval. When tested as anofficial combination by UL,this device takes the place ofa fuse-starter or breakerstarter,XT Type E MMPs areself-protected, meaning theydo not need additional shortcircuit protection of a fuse orbreaker. Type E devices canalso be used with a contactoror other types of UL approvedcontrollers. If tested with acontactor, the combinationmotor controller becomes aType F device.

A current leakage path to ground. An undetected ground fault can burnthrough multiple insulation windings,ultimately leading to motor failure, not tomention risk to equipment or personnelImbalanced phases(voltage and current)Phase loss—current(single-phasing)Uneven voltage or currentbetween phases in a three-phasesystem.One of the three-phase voltages isnot present.When a three-phase load is powered witha poor quality line, the voltage per phasemay be imbalanced.Multiple causes, loose wire, improperwiring, grounded phase, open fuse, etc.Imbalanced voltage causes largeimbalanced currents and as a result thiscan lead to motor stator windings beingoverloaded, causing excessive heating,reduced motor efficiency and reducedinsulation life.Single-phasing can lead to unwantedmotor vibrations in addition to the resultsof imbalanced phases as listed above.• Thermal trip behavior is defined byUL, CSA and IEC standards.• Trip class is settable from 10A,10, 20, 30Fixed protective setting that takes thestarter offline if ground fault currentexceeds 50% of the FLA dial setting,i.e., if the FLA dial is set to 12A, theoverload relay will trip if the groundcurrent exceeds 6A.Fixed protective setting that takes thestarter offline if a phase drops below50% of the other two phases.Fixed protective setting that takes thestarter offline if a phase drops below50% of the other two phases.66 Control Products Catalog CA08102001E—September 2010 www.eaton.com

A current leakage pathto ground.Imbalanced phases(voltage and current)Phase loss—current(single-phasing)Phase rotation(phase-reversal)Frequency varianceUneven voltage or currents betweenphases in a three-phase system.One of the three-phase current isnot present.Improper wiring, leading to phasesbeing connected to the motorimproperly.When line frequencyis inconsistent.When a three-phase load is poweredwith a poor quality line, the voltage perphase may be imbalanced.Multiple causes, loose wire, improperwiring, grounded phase, open fuse, etc.A miswired motor. Inadvertent phasereversalby the utility.Malfunctioning alternator speedregulator, or poor line quality caused byan overload of a supply poweredby individual sources.Increase in current draw. Current leadsto heat and insulation breakdown,which can cause system failure.Additionally, an increase in current canincrease power consumption andwaste valuable energy.The motor attempts to drive the load,which has more resistive force due tothe mechanical interference. In order todrive the load, the motor draws anabnormal amount of current, which canlead to insulation breakdown andsystem failure.An undetected ground fault can burnthrough multiple insulation windings,ultimately leading to motor failure.Imbalanced voltage causes largeimbalanced currents and as a resultthis can lead to motor stator windingsbeing overloaded, causing excessiveheating, reduced motor efficiency andreduced insulation life.Single-phasing can lead to unwantedmotor vibrations in addition to theresults of imbalanced phases as listedabove.Phase-reversal can cause unwanteddirectional rotation of a motor. In theevent that the load attached to themotor can only be driven in onedirection, the result could be significantmechanical failure and/or injury to anoperator.Variations in frequency can causeincreases in losses, decreasing theefficiency of the motor. In addition,this can result in interference withsynchronous devices.Motor InsightProtectionThermal trip behavior is defined by UL,CSA and IEC standards.Trip class is settable from 5–30 by 1Provides power factor monitoring and lowvoltage protection features.Provides a configurable Jam setting thatis active during “motor run state” to avoidnuisance trips.Trip Threshold 150–400% of FLA.Trip Delay 1–20 seconds.Motor Insight has ground fault protectioncapability down to 0.15 amps estimatedfrom the existing three-phase CTs usingthe residual current method. That is, thethree-phase current signals should sum tozero unless a ground fault (GF) conditionis present. In the case of a GF, MotorInsight can alarm, trip the starter, or tripan alternative relay that can be used toshunt trip a breaker or light up a warninglight. GF current can also be monitored inreal-time through the advancedmonitoring capabilities.Note: GF settable thresholds vary withmotor FLA. 0.15 amps may not beavailable in all cases.Provides two protection settings thataddress this problem. The user canchoose to set current imbalancethresholds or voltage imbalancethresholds, each of which can trip thestarter. Additionally, both of these maybe monitored through Motor Insight’sadvanced monitoring capabilities,allowing the customer to notice in realtimewhen and where a condition ispresent.Fixed protective setting that takes thestarter offline if a phase drops below 60%of the other two phases.Configurable phase protection, allowingthe user to define the phase sequencingintended for that application. If no phasesequence is required, the user has theability to disable this feature.Advanced monitoring capabilitiesallow the user to monitor frequencyin real-time.88 Control Products Catalog CA08102001E—September 2010 www.eaton.com

Motor Protection and MonitoringOverload Relays42.4Advanced Overload Education, continuedDescription Definition Source ResultLoad ProtectionUnder current orlow powerHigh powerLine ProtectionOver voltageUnder voltagePower-up delayAverage rms current provided to themotor falls below normal operatingconditions.The motor load is drawing more powerthan it should at normal operatingconditions.When the line voltage to the motorexceeds the specified rating.When the line voltage to the motor isbelow the specified rating.Allows for starting motors and loadsin a deliberate fashion.Under current is usually associatedwith a portion of the user’s loaddisappearing. Examples of this wouldbe a broken belt, a dry-pump (lowsuction head) or a dead-headedcentrifugal pump.This is typical of batch processingapplications where several ingredientsflow into a mixer. When a substance’sconsistency changes and viscosityincreases from what is expected, themotor may use more power to blendthe mixture. Out-of-toleranceconditions can be detected using theHigh Power and Low Power settings.Poor line quality.Poor line quality.When there is a power failure, orpower cycle, multiple loads comeonline simultaneously.If under current goes undetected, amechanical failure can and hasoccurred. In the case of a pump,running a pump dry or running a pumpin a dead-headed condition can causeexcessive heating, damagingexpensive seals and breaking downdesired fluid properties.If a high-power fault goes undetected,the result may be a batch of materialthat does not meet specification.An over voltage condition leads to alower than rated current draw and apoor power factor. A trip limit of 110%of rated voltage is recommended. Overvoltage can also lead to exceedinginsulation ratings.An under voltage condition leads toexcessive current draw. This increasesthe heating of the motor windings andcan shorten insulation life. A trip limitset to 90% of rated voltage isrecommended.Multiple loads starting simultaneouslycan cause sags affecting the operationof devices that may prevent successfulstartup.If power is lost to a motor driving apump, it may be necessary to delay arestart to allow the pump to come to acomplete stop to prevent starting amotor during backspin.Motor InsightProtectionMotor Insight has two protection settingsto detect this: under current and lowpower. Low power is a more consistentway of ensuring detection as power islinear with motor load, where as currentis not. An unloaded motor may draw 50%of its rated current, but the power drawwill be less than 10% of rated power dueto a low power factor.Monitors the three-phase real power. Ifthe real power value is estimated abovethe set threshold for the set length oftime, a fault is detected and the overloadwill trip the starter. Additionally, powercan be monitored in real-time.Monitors the maximum rms value ofthe three-phase voltages. If the rmsvalue rises above the set threshold forthe set length of time, a fault is detectedand the overload can trip the starteror send and display an alarm of thecondition. All line-related faults havean “alarm-no-trip” mode.Monitors the minimum rms value of thethree-phase voltages. If the rms valuedrops below the set threshold for theset length of time, a fault is detectedand the overload can trip the starter orsend and display an alarm of thecondition. All line-related faults havean “alarm-no-trip” mode.Configurable to delay closing the faultrelay on power-up. For each Motor Insightcontrolling a motor, a different setting canbe programmed, helping to maintain theintegrity of your line power.424242424242424242424242424242424242424242424242424242424242Control Products Catalog CA08102001E—September 2010 www.eaton.com 89
