MonitoringThe C30 is a digital controller thatprovides digital I/O and program-mable logic. As a member of theUR family, the C30 offers eventrecording, oscillography and datalogging (see page 7). The C30offers additional advanced moni-toring features such as:
Digital Counters
The digital counters are used tocount the number of state transi-tions between Logic 0 to Logic 1.The FlexLogic™ operand inputs(UP and DOWN) are provided toincrement or decrement the accu-mulated counter value. Thecounter can be utilized to countfunction operations such as thepickup or operation count of anyinternal relay element, thechanges of state of an external
contact such as a breaker auxil-iary switch, or pulses from awatt-hour meter.
Digital Elements
There are 16 user-programmabledigital elements which can beused to monitor any FlexLogic™operand to present a targetmessage and/or enable eventrecording depending on theoutput operand state. The digitalelement settings include a targetname, a blocking input from theFlexLogic™ operand, and a timerfor pickup and reset delays forthe output operand.
As an example, a digital elementin conjunction with the voltagemonitor on a Form A outputcontact can be used to supervisethe integrity of a trip circuit of abreaker.
Transducer I/O
The relay can receive signalsfrom external transducers andconvert them into a digitalformat. These inputs can be usedto monitor temperatures, DC volt-ages, transformers tap changerposition and more.
Two types of analog signals canbe received:
DCmA type signals in the range of-1 to +20 DCmA, suitable for usewith most common transducers
RTD type signals from externalresistance temperature detectors
The transducer values are avail-able locally and remotely and canbe stored in the oscillography fileor data logger.

User-Definable Protection Functions
The relay contains eightFlexElements™ which can beprogrammed to respond to varia-tions in any quantity measuredby the relay.
Remote I/Os
URs can exchange digital stateinformation via the UCA2 GenericObject Oriented Substation Event(GOOSE) mechanism. This peer-to-peer sharing of state information isessentially an addition to existingFlexLogic™ functionality to allowdistributed FlexLogic™.
Remote outputs originate as GOOSEmessages to be transmitted toremote devices. Each GOOSEmessage contains data which identi-fies the originator, and is transmittedwhen required. Remote inputs origi-nate as GOOSE messages fromremote devices. A receiving relay isprogrammed to capture messagesfrom selected originating devices.

Protection andControlThe C60, a digital breakermanagement relay, providesbreaker monitoring and control inone integrated package. Thismember of the Universal Relayfamily offers advanced protectionwhich includes:
Voltage Elements
The C60 includes the following: Phase undervoltage elements;
each element has three individ-ual phase undervoltagecomponents
Auxiliary overvoltage and under-voltage elements
Breaker Failure
Two independent breaker failurefunctions detect both single andthree-pole tripping schemes(selectable). Breaker auxiliarycontacts and/or current supervi-sion are used to determine abreaker fail condition. This func-tion can be initiated and blockedinternally and externally via inputcontacts or communications.
Autoreclosure
A single-pole and three-polecapable autoreclosure is providedwhich simultaneously controlstwo breakers and performssequential reclosing.
Synchronism Check
This function supervises manualand automatic breaker closing.The feature checks for permissi-ble levels of DV, DF and Df ordead source condition. Two iden-tical synchronism check elementsare included.
Breaker Control
The relay allows control of one ortwo breakers locally, throughremote communications orcontact inputs. A breaker polediscrepancy is included in thebreaker control scheme. Breakerposition is indicated by LEDs onthe faceplate.
User-Definable Protection
Functions
Eight FlexElements™ can be pro-grammed to respond to varia-
tions in any quantity measuredby the relay. Application exam-ples include: positive sequenceovercurrent, negative sequenceovervoltage, overpower, lowpower factor, temperature differ-ential, and frequency rate-of-change.
Monitoring andMeteringBasic metering of current, voltageand frequency as well as basicevent recording, oscillographyand data logging are commonacross the UR platform (seepage 7). The C60 provides addi-tional monitoring and meteringwhich includes:
Breaker Contact Arcing Current
(I2t) Monitoring
The C60 tracks the per-phase wearon the breaker contacts by measur-ing and integrating the currentsquared passing through the break-er contacts as an arc. The per-phasevalues are added to accumulatedtotals for each phase and com-pared to a programmed thresholdvalue. The measurement for eachphase is available locally andremotely and can be stored in theoscillography file or data logger.
Transducer I/O
The relay can receive signalsfrom external transducers andconvert them into digital format.These inputs can be used tomonitor temperature, DC voltage,transformer tap changer positionand more. Two types of analogsignals can be received:
DCmA type signals in the range of-1 to +20 DCmA, suitable for usewith most common transducers
RTD type signals from externalresistance temperature detectors
The transducer values are avail-able locally and remotely and canbe stored in the oscillography fileor data logger.

for specific applications. Simplealarm messages provide easynotification.
Communications
Integrate process, instrumenta-tion and electrical requirementsin a plant automation system byconnecting PQM meters togetherto a DCS or SCADA system. Acomputer running PQMPC canchange system setpoints, moni-tor values, status and alarms.Continuous monitoring mini-mizes process downtime byimmediately identifying potentialproblems due to faults orchanges from growth.
RS485 ModBus® 1,200 to19,200 bps
Mini RTU SCADA systemcomponent
Measure actual values Read status Issue control commands Load all setpoints from a file Change individual setpoints
The standard version PQM comescomplete with a front RS232 portwhich can be used for datacollection, printing reports orproblem analysis without disturb-ing the main communicationinterface to rear RS485 port.
Future Expansion
The PQM uses non-volatile flashmemory for firmware storage.This allows future productupgrades to be loaded via theserial port. Upgrades can also beaccessed from www.geindustri-al.com/Multilin.
Standard FeaturesThe PQM is a digital meteringdevice that provides continuousmonitoring of a three-phasesystem. It provides metering ofcurrent, voltage, real and reactivepower, energy use, cost of power,power factor and frequency.
When portable monitoring of athree-phase system is required, aPortable PQM is the ideal choice.This version offers the samefeatures as the panel mount PQMin a rugged carrying case. ThePPQM additionally acts as apower management tool, a trouble-shooting tool and a datacollection device.
In either form, the PQM canprovide users with advancedfeatures for monitoring andmetering which include:
Mounting Versatility
The panel mount with display offersan easy local interface. Standardmodels have RS485 ModBus®
communications for programmingand monitoring. Users can replaceexpensive additional devicesby adding the CONTROL, TRANS-DUCER and POWER analysisoptions to the PQM as required.
Metering
Each voltage and current issampled 64 times per cycle for0.2% accuracy true RMS TrueRMS or displacement (fundamen-tal) quantities.

A keypad and illuminated 40character display provide localsetpoint setting and monitoringvalues and status.
Alarms
Any of the assignable outputsmay be used to trigger an alarm
Initially PQM meters can be usedas stand-alone units. Open archi-tecture allows connection toother or ModBus®-compatibledevices on the same communica-tion link. These can be integratedin a complete plant wide systemfor overall process monitoringand control.
OptionsThere are a variety of optionsavailable to the user, allowing arange of custom configurations:
Transducer
Four Analog Outputs: four isolat-ed analog outputs can be used toreplace eight analog transducers.Output signals can be selectedfrom any of the measured param-eters for direct interface to a PLC.
Analog Input: with the analoginput and an output relay for selec-tion, two transducers (such astemperature or water level) can bemonitored and used for control.
Connect two 4 to 20 mA transducers forprocess variable measurement and control.
Second Rear Comm Port: an addi-tional rear RS485 comm port isprovided for simultaneous moni-toring by process, instrument,electrical or maintenance personnel.
Redundancy in high security systems isprovided by the 2nd RS485 comm port.

Control
Three Output Relays and FourInputs: measured parametersfrom the standard PQM can becombined with setpoints and I/Osfor control applications. With thecontrol option, three outputrelays and four switch inputs areadded along with programmablesetpoints to make a mini RTU.Output relays can also becontrolled via the communicationport or assigned to differentsetpoints for custom program-ming to accommodate manysituations. Possibilities include:
Undercurrent alarm for pumps Over and undervoltage for
generators Unbalance alarm for rotating
machines Dual level power factor for
capacitor bank switching Underfrequency/demand output
for load shedding resulting inpower cost savings
kWh, kvarh and kVAh pulseoutput for PLC interface
Power factor setpoints and two output relayscan be used for two-level capacitor bankswitching.
Power Analysis
Data Logger (Trending): trending isuseful as a troubleshooting aidwhen a problem is detected.Measured values can be selectedand plotted with a programmablesampling rate to suit the time inter-val of interest. The generated chartrecorder screen can be printed orexported to other programs forreport writing.

PQM/PPQM Power Quality Meter
Record trends of measured parameters over time.
Harmonic Analysis: non linearloads such as variable speeddrives, computers and electronicballasts can cause harmonicswhich may lead to problems suchas nuisance breaker tripping, tele-phone interference, transformer,capacitor or motor overheating.For fault diagnosis such asdetecting undersized neutralwiring, need for a harmonic ratedtransformer, or effectiveness ofharmonic filters, details of theharmonic spectrum are usefuland available with the poweranalysis option.
Harmonic spectrum analysis can identifyproblems and ensures implemented changeswork correctly.
Waveform Capture: voltage andcurrent waveforms can becaptured and displayed on a PCusing the PQMPC programsupplied with the PQM or usingthird party software. Distortedpeaks or notches from SCRswitching provide clues for takingcorrective action.
Voltage and current waveforms providevaluable insights into system problems.
Event Recorder: alarms, setpointtriggers, input and output eventscan be stored in a 40 event recordand time and date stamped bythe internal clock. This is usefulfor diagnosing problems andsystem activity. Minimum andmaximum values are also contin-uously updated and timestamped.
Trace Memory: the PQM can beconfigured to record a maximum of36 cycles of data on all voltage andcurrent inputs based on overvolt-age, undervoltage, overcurrent orswitch input state change.
Software
PQMPC Program
PQMPC is a Windows®-basedprogram that can be used toenter setpoints, read meteredvalues, monitor status and evalu-ate power quality. All datacontinuously gathered by thePQM can be transferred to a thirdparty software program fordisplay, control or analysis viathe communications interface.
Once all setpoints have beenentered they can be downloadedinto any PQM or stored in a filewith a tag name for later reference.
Screens are available for moni-toring all measured values suchas current, voltage, or power.Status of alarms and controlsettings can also be displayed.
Voltage and current waveshape cangive important information aboutwhat is happening on a system. Forexample, non linear loads such ascomputers or variable speed drivesmay introduce distortion that indi-cates filtering is required.

Harmonic analysis can provideearly warning of problems, help-ing to prevent equipment damageor nuisance breaker tripping.
PQMPC enables waveformcapture information to be trans-ferred to other programs forinclusion in reports and printouts.Routine event logs of demand orsampled voltage can also becreated and printed out.
To verify correct installation, thesimulation mode substitutesprogrammed currents and volt-ages for real ones. This powerfultool is also an excellent trainingaid for plant personnel.
URPC Program
The Windows®-based URPCprogram allows the user to createsingle line diagrams for substa-
tion and system monitoringschemes. Additionally, annuncia-tor panel viewing, metering, andsettings changes can also beperformed using the program.With the URPC program the usercan access multiple PQMs ordifferent devices for metering inreal time. The program may beused locally through the RS232serial port or remotely throughthe other ports on the device.

Functional Block Diagram
ProtectionThe MIW, part of the M Family, isa digital relay that provides direc-tional power and loss of fieldprotection for generators of anysize. Advanced protection func-tions include:
Directional Reverse Power
If three-phase total powerexceeds the pickup level in thereverse direction (negative MW)for a period of time, a trip willoccur. The pickup level is set byper unit of generator MW calcu-lated from rated MVA and powerfactor.
If the generator accelerates viathe power system rather than theprime mover, the reverse powerelement may be blocked for achosen time period.
Directional Low Forward Power
If the three-phase total power in theforward direction (positive MW)falls below the pickup level for achosen period of time, an alarm willoccur. The pickup level is pro-grammed as above in directionalreverse power.
The low forward power elementis active only when the generatoris online. The pickup level shouldbe set lower than expected gener-ator loading during normaloperations.
Loss of Excitation
Loss of excitation is detected viaan impedance element. If theimpedance falls within the imped-ance circle for the delay timespecified, a trip will occur. The usercan enable circle #1 and/or circle#2 to tune the protection feature totheir system. The larger circlediameter can be set to thesynchronous reactance of thegenerator xd, and the circle offsetshould be set to the generator tran-sient reactance x’d /2. This elementwill be blocked if there is a fusefailure condition or if the generatoris offline.
Fuse Failure
The MIW includes a VT fuse fail-ure unit which measures the valueof negative sequence voltageagainst positive sequence voltageand the current value.
Inputs and Outputs
The factory configuration of MIWinputs and outputs can be easilymodified using M+PC software.Two digital inputs and six relayoutputs are provided, four of themprogrammable. These configurableoutputs can be assigned either to aset of pre-configured values, or toan OR/NOT combination of thesame values.
Configurable Logic
Four configurable logic schemescan be implemented via fourpreconfigured logic gates andtimer cells through a graphical userinterface. The MIW configurablelogic outputs can be used toconfigure digital outputs and LEDs.
Monitoring andMeteringThe MIW provides meteringvalues for Ia, voltage values, P, Q,S, V1, V2 and angle. A 24 eventrecord and oscillography datahelp with troubleshooting andperformance analysis.

GE Multilin
ProtectionThe MIN, a member of the MFamily of protection relays, is adigital relay that provides grounddirectional protection for feedersof any voltage level and backup/auxiliary ground directionalprotection for transformers,generators and motors. The MINoffers advanced protection thatincludes:
Ground Time Overcurrent
Ground TOC protection can beset from 0.1 to 2.4 times In. Fourseparate ANSI or IEC TOC curvescan be selected in addition to auser configurable curve. ANSIand IEC curves include: definitetime, normal inverse, veryinverse, and extremely inverse.For each curve, different timemultipliers may be set. Thisallows the selection of the opti-mum curve for co-ordination withspecific equipment.
Ground IOC Units
Two separately adjustable groundIOC units can be independentlyenabled. The pickup setpoint canbe set from 0.1 to 30 times In andthe time delay from zero to 100seconds.
ALGORITHM 1: Neutral connected
to ground solidly or through a
resistor. Ground Directional Control
This unit offers directional control tothe Ground IOC Units. The supervi-sion is polarized by zero-sequencevoltage and/or current, withadjustable torque angle. The direc-tional supervision is adjustableindependently for each overcurrentunit. Programmable performancelogic for polarization voltage loss isincluded. This algorithm is used inthe MIN option E model.
ALGORITHM 2: Neutral isolated
from the ground. Isolated
Ground Directional Control
The MIN provides directional pro-tection for ungrounded systems.In this type of system the neutralis completely isolated from theground. As a result, the groundfault current value is minimal andproduced only by the line capaci-tive coupling. The algorithm is
based on the presence of thiscapacitive current plus the detec-tion of an overvoltage condition.This algorithm is used in MINoption S models.
ALGORITHM 3: Neutral connected
to ground through a Petersen Coil
The MIN provides directionalprotection for systems where theground connection is donethrough a Petersen coil. Thisscheme is known as a groundresonant circuit or ground faultneutralizer. The algorithm isbased on a real power directionalprotection unit, being intrinsicallya ground directional functionpolarized by zero sequence volt-age. The torque angle defines theoperation zone and the threemagnitudes (residual current,residual voltage and real power)define the pickup value. This algo-rithm is used in option S models.
Direct Comparison Scheme Logic
Directional comparison schemefunctionality can be used as aninstantaneous unit or a time-delayed device in pilot protectionschemes.
The MIN will work in a number ofpilot schemes in conjunction withdistance relays. Note that most ofthese schemes will require theuse of the two available digitalinputs. This logic is available inMIN-L models.
Inputs and Outputs
The factory configuration of MINinputs and outputs can be easilymodified using M+PC software.Two digital inputs and six relayoutputs are provided, four ofthem programmable. Theseconfigurable outputs can beassigned either to a set of pre-configured values, or to anOR/NOT combination of the samevalues.

DRS single and three phase reclosing
Functionality
Recloser
The recloser portion of the DRSprovides both single pole andthree pole reclosing for one ortwo breakers. The reclosingsequence can be set to any of 7programs:
R1 - LO R3 - LO R1 - T3 - LO R3 - T3 - LO R1 - LO or R3 - LO R1 - T3 - LO or R3 - T3 - LO R1 - T3 - LO or R3 - LO
R1 = Single pole reclose
R3 = Three pole reclose
T3 = Second step three polereclose
LO = Lock-out.
The reclosing sequence is startedby the receipt of a reclose initia-tion signal. After the set timedelay, a reclose output is issued.If only one shot has been chosen,the recloser will go to lockout if asecond initiation input is received
prior to the expiration of the resettime. If two shots have beenchosen, a second delayed shotwill precede the lockout state. Therecloser can be reset from lockoutusing a command or automatical-ly after a set time. Manual closingcan be done energizing an inputto the DRS. Closing conditionswill be directed by the DRS (volt-age synchrocheck, DL-DB, DL-LB,LL-DB, external input).
Features
Pole Disagreement
A pole disagreement tripping oralarm output per breaker isprovided. The function supervisesthe breaker auxiliary contacts(per phase) status and with atimer supervision, determines if apole disagreement conditionexists.
Closing/Reclosing Conditions
Conditions are independently setfor closing and for reclosing, perbreaker. Closing/reclosing condi-
tions checked by the DRS are: Voltage synchrocheck: verifies
the magnitude, phase angle andfrequency difference betweenthe two voltage signals at bothsides of the breaker
Undervoltage conditions: DeadLine-Dead Bus, Dead Line-LiveBus, Live Line-Dead Bus(Dead/Live voltage levels aredefined by settings)
External permission: a digitalinput can be used to permit theclosure/reclosure
Outputs
The DRS has independent outputconfigurable contacts per break-er. Additionally, alarm outputs areprovided.
Easy to Configure
The DRS is configured using GE-INTRO software. This is agraphical Windows® basedprogram that allows easy config-uration. No training orprogramming skills are required.

ProtectionThe DBT is a digital relay thatsupervises the integrity of thebreaker’s tripping and closingcoils. The relay checks the conti-nuity of the coil regardless of thestatus of the breaker on single orthree-pole tripping schemes. Itcan supervise three coils at thesame time. A DC undervoltageunit checks the circuit breakeroperating power supply voltage.
Monitoring andMeteringThe DBT relay has an advantageover coil supervision relays whichare based only on continuity, as italso measures real resistance. Theadvantage of this method is selec-tivity. The DBT is able to detect fail-ures in the circuit breaker coilseven when there are coils fromdifferent auxiliary circuits connect-ed in parallel. In this situation a fail-ure or a broken lead would not bedetected based only on continuity,because there would be an alterna-tive path in the parallel coil. Theresistance measurement used bythe DBT will detect this condition.In order to make this resistancemeasurement it injects a 5 mAcurrent, measures the voltagedrop, and calculates the resistance.

DBF digital breaker failure
DescriptionThe DBF is a digital breaker fail-ure relay that provides phase andground backup protection if theprimary circuit breaker fails toclear a system fault.
Breaker failure protection is criti-cal in any backup relayingscheme. This protection musthave not only sensitivity anddependability, but also a highlevel of security because it isprotecting the busbars. The relia-bility must also be the same asthat of a busbar protection relay.
By using digital technology theoperation time of the DBF hasbeen improved.
An associated function protectsagainst electrical arcing betweenthe contacts of the breaker whenit is opened. This will help toprevent damage to the breaker.This function uses three verysensitive overcurrent detectorsset to the line capacitive current.
Three setting groups are avail-able, with the active groupselected by a setting or an input.There are 14 configurable inputsand 16 outputs (11 configurable).
The DBF meters the currentcontinuously. It also monitors thebreaker health I2t value. It has anevent recorder that can store thelast 165 events with a 1 ms reso-lution. It can store up to 4oscillography records with 66cycles each.
The local user interface includesa keypad and display. There are17 LED indicators, one a twocolored system alarm, and 16 redconfigurable to any of the 32alarms available. There are threecommunications ports, one onthe front panel and two on therear. It has 2 tripping steps.
Protection andControl
Overcurrent Protection
The DBF’s three phase overcur-rent protection (50PBF) consistsof single or three-phase breakerfailure initiation units with inde-pendent pickups and time delays.It also has three phase direct tripprotection (50XNF), which maybe used for three phase breakerfailure initiation without overcur-rent. The DBF also includesground overcurrent protection(50NBF).
Two step breaker failure opera-tion is included where each stepoperation may be activated bysingle, two or three phase over-current functions. Both steps aretime delayed and offer a widerange of settings.
Using independent timers perphase for the first step permits acorrect coordination with thesecond zone in case of evolvingfaults in single-pole trippingschemes.
The fast tripping logic permitsaccelerated tripping during three-phase faults. This is particularlyuseful in maintaining powersystem stability where selectivefast tripping is appropriate.
Internal Arcing Protection
If an electrical arc exists betweenthe contacts of an open breaker itcan eventually destroy the break-er. The DBF uses three verysensitive overcurrent detectorsset to the line capacitive currentto protect against internal arcing.
Settings Groups
Three groups of settings areavailable for the DBF. The activegroup may be selected by asetting or by an input.
Inputs and Outputs
The enhanced model DBF has 14configurable inputs, in groups of2 and 3 inputs.
There are 16 outputs with thefollowing assignments:
1 breaker failure pickup 2 breaker failure fix tripping
contacts 1 internal arc contact 1 alarm contact 5 spare configurable contacts 6 latching relay contacts (option-
al)
The logic for configurableoutputs consists of a combinationof NOT, AND, and OR gates appli-cable to trips, alarms and pickupsof all the protection and controlfunctions, internal protectionstatus, control, digital inputs, etc.
A basic DBF model is also avail-able which includes 6configurable inputs and 10outputs (5 of which are config-urable).
Monitoring andMetering
Breaker Monitoring
The breaker status is monitoredcontinuously. The cumulative I2tvalue is stored and used forbreaker health monitoring.
Event Recorder
The DBF records up to 165 eventsin non-volatile memory. Recordsinclude date and time with 1 msresolution, type of event, currentmeasurements and relay status.
Oscillography
The DBF system includes anoscillography recorder. It can beactivated by any of the protectivefunctions pickup or trip or by anexternal input. Records have aresolution of 16 samples percycle. Up to 4 records may bestored with up to 66 cycles each,with pre-fault cycles adjustablebetween 2 and 10 cycles.
The DBF can store up to 4 oscillographyrecords
Protection Status Self-checking
The DBF performs self tests bothat start up and continuously inthe background during operation.

User Interfaces
Keypad and Display
The DBF has a 20 button keypadand a 2 line by 16 characteralphanumeric LCD. This allowslocal user interface without acomputer.
LED Indicators
The DBF has 17 LED indicators.One is a two color system alarm.The other 16 are red, and areconfigurable to any of the 32alarms available. Each LED canbe configured with or withoutmemory.
Communications
The DBF has three communica-tions ports, one on the frontpanel which is connected to oneon the rear panel, and a thirdindependent rear panel port.
The first two ports allow commu-nication through GE-LOCALsoftware, either locally with a
laptop computer, or remotely to aprotection dispatch center. Thissoftware allows the user to visu-alize measurements and status aswell as the relay’s time synchro-nization.
The third port connects the userto a communications network,through GE-POWER software, tothe part of a DDS integratedsystem. These applications arepart of GE-NESIS (GeneralElectric NEtwork SubstationIntegration Software) used by theDDS system.
GE-LOCAL software is provided for DBFcommunication

DFF Digital Frequency Relay
Protection andControl
Frequency Functions
Under normal conditions, thegenerated frequency of thepower system must match withthe load requirements. Whenabnormal conditions occur thereare changes in the systemfrequency. If the changes aresmall the frequency can becorrected through the normaladjustment of the system genera-tor. However, when the load isincreased above the generatorrating the generator can nolonger correct the speed and thefrequency begins to drop. TheDFF is applied directly to thegenerator to protect againstdamage, and throughout thesystem to “shed” load in anattempt to regain frequencystability.
The DFF has 8 frequency units.Each unit can be configured as arate of change unit or as anabsolute frequency unit. Theseunits are supervised by an under-voltage unit. The number ofcycles needed to consider a tripcondition can also beprogrammed.
If the frequency unit isprogrammed as an absolute unitthe relay will trip when thefrequency is under theprogrammed value during thetime delay value. When the unitsare programmed as rate ofchange units the relay will tripwhen the frequency is under theprogrammed value and theinstantaneous variation of thefrequency with respect to time isgreater than the programmedvalue. In this case the time delayvalue will be ignored.
Voltage Functions
One overvoltage and one under-voltage unit is provided. Thevoltage functions are singlephase units. The frequency unitsare supervised by an undervolt-age unit.
Multiple Settings Groups
Three separate groups of settingsare stored in the DFF’s non-volatile memory, with only onegroup active at a given time. Thisallows the relay to respond tochanging conditions by selectingthe appropriate settings group.The active settings group can beselected via a user command orthrough a digital input. Certainsettings are common to allsettings groups.
Configurable Inputs and Outputs
There are 14 configurable inputsand 33 configurable outputs(DFP1000), providing the DFFwith high flexibility in load shed-ding schemes. AND/OR/NOT logiccan be applied to configure theoutputs. GE-INTRO software isprovided to configure the inputsand outputs.
MONITORING ANDMETERING
Event Record
The DFF has an event record thatcan store up to 150 events withthe date and time stamped to thenearest millisecond. This providesthe information needed to deter-mine the sequence of events,which helps the diagnosis ofrelay operation.
Oscillography
The DFF offers two types of oscil-lography records: voltagerecording, at 16 samples percycle, 66 cycles long (approxi-mately 1 second), and networkfrequency recording, at 2samples per cycle, with a storagecapacity of 1586 cycles (approxi-mately 30 seconds). The type ofoscillography record is selectableby a setting. GE-OSC software isprovided to allow the user todisplay and analyze the oscillog-raphy records.
The DFF can store four oscillography records

F485 communication converter
DescriptionThe F485 is a self-containeddevice for converting betweenRS232, RS485 and fiber opticsignals. The F485 is electricallyisolated to improve communica-tions in noisy environments. Theconverter uses internal switchesto select the signal conversiontype and communication rates upto 57600 bps. The F485 converteruses the data on the serial portsto determine direction and there-fore requires no hardwarehandshaking signals from thecomputer. The F485 converter canbe powered via the poweradapter supplied or by connect-
ing an external 9VAC/VDC sourceto the power supply terminalslocated at the back of the case.The F485’s versatility and simpledesign makes it ideal for use withall GE Power Management prod-ucts in direct and modemcommunications.
Options
Fiber Optic Transmitter/Receiver
The fiber optic transmitter andreceiver used in the F485 convert-er utilize 820nm wavelengthtechnology and are designed tooperate with multimode fibersizes 50/125mm, 62.5/125mm and100/140mm using ST terminated
cables. The ST connectionsprovide repeatable connectionswith low attenuation.
Control Voltage
The F485 converter can bepowered by the 120 or 220 VACpower adapter supplied, or byconnecting an external 9 VAC/9VDC source. The 120 VAC adapterhas a standard North Americanplug. The 220 VAC adapter hasbeen designed for Europeanmarkets where voltage is 220VAC.

F485 simplifies communication between Intelligent Electronic Devices (IEDs), computers and a broad range of other combinations.
Features
RS485 direction control
Two-wire RS485 is by nature halfduplex and requires a means forswitching between a receive ortransmit state. The F485 converteruses the incoming data to controlthe direction and thereforerequires no control signals fromthe master device (RS232 orfiber) to switch from transmissionto receive mode after the lastcharacter has been transmitted.The length of time is fixed at thetime of 3.5 characters at theselected baud rate making it suit-able for use with ModBus® RTUprotocol.

DTE/DCE Control
The DTE/DCE setting reverses thetransmit/receive data lines on theRS232 side. For communicationsbetween a computer and a slavedevice, such as an IED, DTE(direct) should be selected. Whenconnecting the F485 converter toa modem or other data communi-cations equipment, DCE shouldbe selected.
Configuration
The converter box is configurablevia two internal dip switch bankswhich are accessible by removingthe converter box cover.Switches set the baud rate forRS485 communications, whether
the converter is DTE (RS232direct) or DCE (RS232 modemwith transmit and receivereversed) and the converterconversion mode.
Mounting
Two different mounting arrange-ments are possible. The first is byusing the two mounting holesinside the plastic case along withthe mounting screws supplied.The second and less permanentmethod is to use the Velcro®material supplied for attachmentto the side of a computer or desk.Visible LEDs on the front panelshow transmit/receive activity.
