Protection and ControlThe239isadigitalmotorprotectionsystemdesignedfor threephaseACmotorsandassociated mechanical equipment .Advancedprotectionfeaturesinclude:
thermal overload
This function calculates the thermalcapacity used by the motor duringdifferent stages of themotor operation.Thevalue isupdatedbasedonthetime-currentoverloadcharacteristicsand themotoroverloadlockouttimesetpoints.
Motor starting
Duringacceleration,themotorisprotectedbyanI2tovercurrentcurvewhichpassesthrough the setpoints “Locked RotorCurrent” and cold “Safe Stall Time.” Therunningoverloadcurveisnotactiveduringacceleration,thereforeprovidingstartingprotection independent of runningprotection.
Motor running
To protect the motor against overloadswhile it is running, select one of 15different curves to accurately matchthe motor overload characteristic.Curves automatically adjust for hotmotor compensation to ensure correctthermalmodeling. For somenon-typicalapplications,therelaycanbeorderedwithadditionalcustomprogrammableoverloadcurves,allowingtheusertoconstructtheprecise curve thatmatches the thermalcharacteristics of the protected motor(MOD506).A user-programmable overload lockouttime controls the motor cooling rate. If
theprocesscriteriarequireshortercoolingperiods, particularly for small motors, adifferenttimecanbeused.The minimum level of thermal capacitythattherelaywillcalculateundernormaloperationwillbedeterminedbytheHot/Cold stall time ratio, which distinguishesbetweencoldandhotmotorconditions.AnAutoResetfeatureresetstheoverloadtriponcethethermalcapacityhasdecreasedto15%orless.An immediate overload alarm alertsthe operator. This may be useful forsystemsthatdonotnormallyexperienceoverloads.
An immediate overload pickup setpointis also available. The relay can also beorderedwiththeoptiontoallowtherelaytolearnthethermalcapacityusedduringsuccessfulstarts.
Hot Motor
Thisfunctionutilizesthermalcapacityused(TCU) value to initiateahotmotoralarmwhen the TCU is approaching themotorthermallimit(100%TCU).
Immediate overload alarm
Thisfunctionisusedtoalarmonamotoroverload condition that requires an
immediate intervention to eliminate thecauseofthesuddenoverload.
Phase short Circuit
Thiselementprovidescompletephase-to-phase and Phase-to-ground protection.TriporAuxiliarycontactscanbeselectedtooperateinstantaneously,orwithatimedelayupto60seconds.
Mechanical Jam
This function prevents motor damageduring abnormal operational conditions.Quick motor shut down can reducedamage to gears, bearings, and othermechanical parts associated with thedrivesystem. Acurrentsurgewillcausetherelayassignedtothemechanicaljamprotection to become active. The usermaysetthepickuplevel,timedelay,andinhibits.
Undercurrent
This function is typicallyused toprotectpumps from loss of suction, fans fromlossofairflowduetoacloseddamper,orconveyorsystemsfromabrokenbelt .Thisfunctioncanbeusedasanalarmorasatrip,ordisabledifnotrequired.Alternativelythisfeaturecanbeusedasapre-overloadwarning by setting the undercurrentpickup above the normal operatingcurrent but below the rated full loadcurrent.
single-Phase (Unbalance)
Currentunbalance is another significantcontributor to motor overheating. Theunbalance protection function has anunbalance pickup level and time delaythatcantriggeratriporanalarm.Typicalpickup is intended to detect and clearsinglephasing.Use thealarm level asawarningforsystemvoltageunbalance.

WhentheresidualconnectionofthephaseCTs is used to detect ground currents,nuisancetripscanoccurduringstartdueto unequal saturation of CTs.

Fault Diagnosis
The239keepsarecordofthecauseofthelast five trips issued. The relaywill alsorecordthephasecurrent,groundcurrent,and RTD temperaturesmeasured at thetimeofthelasttrip.
Motor alarmingAlarm functions include immediateoverloadwarning,unbalance,undercurrentand internal self check fault . Often analarmcanbegeneratedsoonenoughtoenablecorrectiveactiontobetakenbeforeatripoccurs.
testing
While periodic calibration is notrequired,thePICKUPLEDisusefulduringcommissioning or routine verificationto indicate the pickup point for phaseoverload or ground. A simulation modeis also available that enables simulatedcurrentstobeusedwithouttheneedforarelaytestset.Thisisidealforverificationofsettingsand training. Itallows forcingofoutputrelays,LEDs,switchinputs,RTD,Thermistor input resistance, and Analogoutputs.
