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.
