If used with a VSA12,VSA16, or VSA20 recloser, refer to Service InformationS280-45-1. If used with a VSO12, VSO16, or VSO20recloser, refer to Service Information S280-57-1.

The information contained in this manual is organized intothe following major categories: Safety Information, Prod-uct Information, Programming and Operating the Control,Installation Procedure, Testing, and Maintenance Infor-mation. Refer to the table of contents for page numbers.

Read and understand the contents of this manual and fol-low all locally approved procedures and safety practicesbefore installing or operating this equipment.

Additional InformationThese instructions do not claim to cover all details or vari-ations in the equipment, procedures, or process describednor to provide directions for meeting every possible contin-gency during installation, operation, or maintenance.When additional information is desired to satisfy a problemnot covered sufficiently for the user's purpose, please con-tact your Cooper Power Systems sales engineer.

Acceptance and InitialInspectionEach control (Figure 1) is completely assembled, tested,and inspected at the factory. It is carefully calibrated,adjusted, and in good condition when accepted by thecarrier for shipment.

Upon receipt, inspect the control thoroughly for damageand loss of parts incurred during shipment. If damage orloss is discovered, file a claim with the carrier immediately.

Handling and StorageTake care during handling and storage to minimize thepossibility of damage. If the control is to be stored for anylength of time before installation, provide a clean, dry stor-age area. If storage is in a humid atmosphere, make pro-visions to keep the cabinet heater energized.

Note: To energize the cabinet heater, apply to 120 Vac to Ter-minals 5 and 6 of the input terminal strip mounted verti-cally on the back panel of the control cabinet. Refer toFigure 4.

Control Battery Storage andChargingThe nickel-cadmium control battery is fully charged priorto shipment and is ready for use. The battery should onlybe stored in a fully charged state. Permanent irreversibledamage will result if a battery is stored in a deeply dis-charged state. The battery should be kept on a mainte-nance charge of 15 mA until the control is put into service.After three months of storage, check the open circuit volt-age. The battery will require recharging if it is at or below24 volts at 25˚C (77˚F). Never store batteries at tempera-tures exceeding 47˚C (117˚F), as permanent damage canresult in one month. Storage at or below room tempera-ture is recommended to prolong storage time and main-tain capacity over time.

To maintain the battery charge, energize the control’sbuilt-in charger with AC power applied to the input termi-nal block. If it is not possible to charge the battery with thecontrol’s built-in charger, a portable dual rate bench typecharger, catalog no. KA1142ME3, is available. Thecharger provides a selectable output of either 15 mA formaintaining a charged battery or 50 mA for charging a dis-charged or partially discharged battery. Unless it the bat-tery is known to be fully charged, it should be charged at50 mA for 48 hours (CHARGE switch position) and thenmaintained at 15 mA (MAINTAIN switch position) until thebattery is installed in the control and put into service.

Battery ConnectionsWhen the battery is shipped from the factory, the batterysource is disconnected and its output plug is taped to thecabinet. Connect the battery plug into the mating connec-tor to complete the battery circuit.

IMPORTANT: The battery must be disconnected priorto shipping or storing the control.

IMPORTANT: Connect the control battery when ACpower is connected to the control’s AC supply InputTerminal Block.

Description of ControlThe Kyle Type ME Form 3A electronic recloser control iscomprised of a number of programmable, solid-state elec-tronic circuits that perform the command functionsinvolved in automatic recloser operation.

Control PanelA swing-out front panel contains the programming andoperating elements of the control (Figure 2). The upper,black portion of the front panel contains the plug-in com-ponents and setting knobs for programming automaticrecloser operation. The switches and indicators used formanual operation and service are grouped on the bottom,light portion of the panel.

Minimum-TripResistorsEstablish the minimum-trip current levels forground and eachphase; cartridges aremarked in primaryamps and clamped inplace.

Ground-TripOperation SwitchBlocks all ground tripping in theBLOCK position: Prevents uninten-tional tripping during single-phaseswitching operations.

Ground-Trip SelectorPrograms the number of fastground-trip operations asdefined by the timing plug inSocket 1; the remaining(slower) operations to lock-out are defined by the plug inground-trip Socket 2.

Phase-TripSelectorPrograms the number of fastphase-trip operations asdefined by the timing plug inSocket 1; the remaining(slower) operations to lock-out are defined by the plug inPhase-trip Socket 2.

Reclosing IntervalPlugsDetermines the delay inter-val for each closing opera-tion. The delay value isdetermined by the positionof the plug in the socketadapter. An instantaneousplug is available for the firstreclose interval only.

Ground-Trip TimingPlugsProvide a variety of current-integrated timing curves onindividual plugs for coordi-nating the ground-trip opera-tion with backup anddownline protective devices.

Phase-Trip TimingPlugsProvide a variety of current-integrated timing curves onindividual plugs for coordi-nating the phase-trip opera-tion with backup anddownline protective devices.

Reset-Delay PlugDetermines the delay inter-val before the controlresets after a successfulreclosure during an opera-tion sequence. The delayvalue is determined byposition of the plug in thesocket adapter.

Battery TestTerminalsEnable checking batteryvoltage, charging rate, andquiescent battery currentdrain.

Lockout-IndicatingSignal LampProvides visual indicationof control lockout.

Lockout SelectorPrograms the total numberof operations to lockout.

OperationCounterRecords the cumulativetrip operations of thecontrol.

Sequence RelaySteps the control throughits operating sequence.

Manual ControlSwitchIn the TRIP position, itlocks out the control,advances the sequencerelay to lockout, and dis-connects the batteryfrom the control circuits.In the CLOSE position, itmoves the sequencerelay to the home posi-tion, reconnects the bat-tery, and closes recloser.If held in the CLOSEposition, it will overridecold-load inrush; how-ever, the control will lockout for permanent faults.

Non-ReclosingSwitchSets the control for one-trip to lockout without dis-turbing the lockout settingof the operations selector.

Lamp Test LockoutSwitchEnables testing the signallamp and checking forcontrol lockout.

Control FuseProtects the closing solenoidcoil (on reclosers that employsolenoid closing) if closingvoltage is too low. Connectedin series with the closing con-tactor in the recloser on motor-operated units; connected inseries with the contactorrotary solenoid on reclosersthat employ solenoid closing.

Tie BoardThe front panel is backed by a printed-circuit tie boardwhich supports and interfaces the plug-in circuit boardswith other related circuit components (Figure 3). Program-altering, remote-control, indicating, and general conve-nience accessories can be added to further expand andenhance the application capabilities of the control.

Phase- and Ground-Trip Protective Feature

The phase- and ground-trip protective feature extends themaximum fault-current capability of the ME control to themaximum interrupting rating of the recloser.

The phase- and ground-trip protection feature consists offour Zener diodes bracket-mounted to the back panelalongside the tie board (shown in Figure 3).

Back PanelThe control battery, cabinet heater, surge module forauxiliary power supply, customer connections terminalstrip, and accessory boards are located inside the controlcabinet and on the back panel of the control as shown inFigure 4.

Description of Control OperationLine current flowing through the recloser is sensedby three internally mounted bushing-current transformersin the recloser, one on each phase. When the phase cur-rent or the zero-sequence (ground) current exceeds itsprogrammed minimum-trip value, the electronic controlinitiates the programmed sequence of recloser tripping

and reclosing operations. If the fault is temporary, thecontrol ceases to command recloser operations after thesuccessful reclosing, and the control resets to the start ofits operating sequence after a preset time delay. If thefault is permanent, the control performs its complete pro-grammed sequence of recloser commands and locks outwith the recloser open. Once locked-out, the control mustbe manually reset to the start of its operating sequence,which simultaneously closes the recloser.

Factory-calibrated timing plugs establish the time–currentcharacteristics for both phase and ground tripping. A setof two individual timing curves provides dual timing forboth phase and ground.

A functional block diagram of the control operation isshown in Figure 5. Line current conditions are monitoredcontinuously by three bushing-type current transformersin the recloser, one on each phase. Output of these trans-formers is fed to the trip network in the control, whichincludes the minimum-trip resistors, isolation transform-ers, and rectifier circuits.

When current above the selected minimum-trip level isdetected in one or more phases, the following chain ofevents will occur for an operating sequence of two fastand two delayed operations:

The overcurrent signal is integrated with time on the char-acteristic curve of the timing plug in Socket 1 to producethe signal which energizes the trip circuit. Energizing thetrip circuit connects the battery to the trip solenoid to tripopen the recloser. Simultaneously, the sequence relayadvances to energize the first reclosing interval-delayplug. Upon expiration of this reclosing interval delay, aclosing signal from the control closes the recloser, and thesequence relay sets up the circuitry for the second fast tripoperation.

If current remains above the minimum-trip level, the trip-ping—reclosing sequence of fast and delayed operationsis repeated, as programmed, to lockout.

If the overcurrent is cleared before the operatingsequence reaches lockout, the reset-delay circuit startstiming when the recloser closes into the un-faulted line.When the reset-delay plug times out, the sequence relayis reset to the start or home position and the control isready for another two-fast, two-delayed trips operatingsequence. However, should the fault recur before thereset plug times out, the control will continue its operatingsequence where it left, and the reset delay timing will beerased.

Ground-fault sensing and tripping operations occurexactly the same as phase sensing and tripping, except that zero-sequence (ground) current is sensed instead ofphase current. The ground-fault circuitry includes its ownminimum-trip resistor, fast and delayed trip timing plugs,and number of fast operations setting. Reclose and resetintervals and operations to lockout are common for bothphase-trip and ground-trip modes of operation.

Control BatteryPower to operate the tripping and reclosing solenoids inthe recloser is provided by a 24 volt, nickel-cadmium bat-tery located in the back, upper right corner of the controlcabinet. A temperature-regulated 120 Vac potential bat-tery charger, built into the control circuitry, provides a tem-perature compensated charging current to the battery. AllForm 3A controls require a 120 Vac input to the con-trol to energize the battery charger.

If 120 Vac cannot be provided to the control, the reclosermust be equipped with a factory-installed battery chargeraccessory.

A. In solenoid-operated reclosers (RVE, RXE, VWE,VWVE27, VWVE38, WE, and VWE) a BCT accessorymust be added to the recloser to obtain chargingpower from the line.

Note: Line current flow through the recloser must be aminimum of 40 amps for at least 12 hours per day toprovide sufficient charging power.

B. In motor-operated reclosers (CXE, VSA12, VSA16,VSA20, VSO12,VSO16, and VSML), a potential-typebattery charger accessory must be added to obtaincharging power from the 240 Vac auxiliary powersource of the recloser.

Battery Check ProceduresFollow the check battery procedures to check the batteryvoltage, quiescent drain, and charging rate. The values inthe test procedure is based on testing at 25˚ C (77˚ F).

Note: The control does not need to be connected to a recloserfor the battery check tests.

Check Battery Voltage Procedure

1. Remove the control from service. Refer to the ToRemove Control from Service section in this manual.

2. Disable the control battery charger by opening thefused switch or removing the AC power from the con-trol. Wait 3 to 5 minutes to allow the battery voltage tostabilize prior to testing the open circuit battery voltage.

3. Three battery test terminals in the lower right corner ofthe front panel are used to check the battery voltage,quiescent drain, and charging rate (Figure 6). The lefthand pair of terminals (V) are connected directlyacross the battery to check battery voltage. The redterminal (far left) is battery positive (+).

4. The battery in the control will experience a steadydrain of approximately 1.5–2.5 mA (may be as high as4.5 mA with certain accessories).

5. Measure the battery voltage from the battery test ter-minals on the control front panel. If battery voltage isbelow 24 volts, the battery is either low on charge orfailing. The battery should be removed for rechargingand retested before returning to service.

6. If battery voltage is above 24 volts, perform the fol-lowing load test. While measuring battery voltage,connect a 10Ω, 10 watt resistor across the battery testterminals for approximately 2–3 seconds. For ambienttemperatures above -6˚C (20˚F), battery voltageshould drop by no more than 3 volts from the open cir-cuit voltage.

Note: Either a KA638ME voltmeter accessory or a KMETTester can be used for the load test. Both deviceshave a built in 10Ω load resistor.

7. If the temperature is below -6˚C (20˚F), the batteryvoltage/temperature should follow the lower curve inService Information S280-75-2 Figure 53. If the volt-age falls below the lower curve, the battery should beremoved for bench testing.

!SAFETYFOR LIFE

CAUTION: Equipment damage. Shorting batterypositive to battery negative at the battery test ter-

minals on the control panel will cause damage to thecontrol. The control will be inoperative and possiblemisoperation (unintentional operation of the recloser)can result. T214.1

!

CAUTION: Recloser misoperation. The controlmust be removed from service before disconnect-

ing the control battery. Disconnecting the control batteryfrom an in-service control may cause recloser misoper-ation (unintentional operation). Failure to comply canresult in equipment damage and personal injury. T213.4

IMPORTANT: Battery voltage and charge currentmeasurements can be made while the control is in ser-vice, from the test terminals provided on the face of thecontrol panel. The control must be taken out of servicefor all other battery maintenance, battery replacement,or battery drain tests.

Check Battery Quiescent Drain and ChargingRate Procedure

The righthand pair of terminals (-I-) are connected inseries with the negative battery lead to check quiescentdrain and charging rate. Proceed as follows:

1. Remove the control from service. Refer to the ToRemove the Control from Service procedure in theProgramming and Operating the Control section ofthis manual.

2. Set the control to the home (reset) position by movingmanual operator to CLOSE.

3. Plug a dc milliammeter into the current test terminals.Loosen both terminals slightly and disconnect theshorting link from between terminals.

4. With the battery charger de-energized, current willflow opposite to the direction shown by CHG. Undernormal conditions, quiescent drain will be 1-1⁄2 to 2 mA.However, the shorter time reset plugs and certainaccessories can, as shown in Table 1, increase thequiescent drain above nominal value.

Note: To verify the charge/discharge polarity of the testmeter, momentarily actuate the LAMP TEST/LOCK-OUT TEST toggle switch to LAMP TEST. The dis-charge current is measured.

5. With the battery charger energized, current will flow inthe direction shown by CHG. The charging circuitused in the control is temperature regulated. Thecharging rate will vary depending on the internal con-trol temperature, see Figure 7.

6. Replace and tighten the shorting link between the cur-rent terminals before removing the ammeter.

Note: Bypass diodes in the battery circuit prevent the controlfrom being disabled if the link is inadvertently leftopen.

Temperature-Regulated BatteryChargerAll Form 3A Type ME controls, serial number 50070 andabove, are equipped with a temperature-regulated batterycharger as standard equipment.

DescriptionThe temperature-regulated battery charger provides pro-tection against battery drain and premature battery failureat high ambient temperatures. As the temperatureincreases, the self discharge rate of the control batteryincreases. The temperature-regulated battery chargercompensates for this self-discharge by providing highercharging rates at higher temperatures.

OperationThe temperature-regulated battery charger consists of acharger ballast-surge protection card and a plug-in batterycharger circuit board. It provides an increased chargingrate proportional to the temperature inside the control cab-inet (see Figure 7).

IMPORTANTBeginning with control serial number 53381, the keyslot position of the battery charging board socket hasbeen changed. The key slot on the temperature-regu-lated charging board (MEA1172, 120/240 Vac) hasbeen moved to match the socket arrangement. Thenew charging board can be identified by the revision 6or above marking adjacent to the part number. A bluelabel affixed to the accessory list location guide label,inside the control door, identifies the new temperature-regulated battery charging board.

Note: Controls equipped with CT or potential charger in therecloser are unaffected by this change. They willcontinue to use the MEA 388-1 charging board, withthe key in the original position.

The Form 3A control is preset at the factory for an auto-matic sequence of operations as specified on the orderand should not be disturbed by unauthorized personnel.Changes in the control operating parameters should bemade only by a qualified technician or engineer. The con-trol must be removed from service prior to making anychanges to programmed settings.

The plug-in components and selector switches for pro-gramming the control are located on the black, upper por-tion of the control panel.

To Remove the Controlfrom ServicePrior to changing plug-in components, performing controlmaintainence, making programming changes, or replac-ing the battery on an in-service control, the followingsteps must be taken to prevent possible recloser misop-eration.

1. Switch Ground Trip Block switch to BLOCK.

2. Disconnect control cable from control.

3. De-energize potential battery charger, by opening thebattery charger fuse block switch (shown in Figure 4).

4. Operate the Manual Control switch to OPEN.

5. Unplug the control battery.

To Return the Control to ServiceAfter required work is completed, return the control to ser-vice with the following steps:

1. Check that all plug-ins are properly installed and con-trol settings are correct.

2. Connect control battery.

3. Close the battery charger fuse block switch to ener-gize the potential battery charger.

4. Move Manual Control switch to CLOSE, to ensure thatcontrol is reset to the home position.

5. Reconnect the control cable to the control.

6. Switch Ground Trip Block switch to NORMAL.

Number of Operations SelectorsThe three selector knobs in the upper left corner of thepanel (Figure 8) establish the operating sequence of thecontrol. From one to four total operations to lockout canbe selected on the center LOCKOUT knob. GROUNDTRIP SOCKET 1 selector knob to the left establishes thenumber of ground trip operations (0 to 4) according to thetime–current characteristic curve of the timing plug inGROUND TRIP SOCKET 1 . The balance of the ground-trip operations to lockout are then performed according tothe characteristic curve of the timing plug in GROUNDTRIP TIMING SOCKET 2 .

PHASE TRIP SOCKET 1 selector knob to the right per-forms the same function for phase-trip sequence selection.

!SAFETYFOR LIFE

Reclosing Interval Timing DelaySelectorsDepending upon the number of operations to lockout,one, two, or three reclosing intervals (each individuallytimed) can be programmed. The reclosing intervals areestablished by the solid-state timing plugs in the upperright corner of the panel (Figure 9). Times of 1, 2, 5, 7, 10,15, 30, and 45 seconds are available on a multiple-settingplug (Figure 9). The small white arrow at the top of theplug indicates the value selected. Selection is determinedby the position of the plug in the socket adapter (Figure10). INST (instantaneous) and 60 second, single-valueplugs are also available. Single value plugs do not use thesocket adapter.

The INST reclosing interval plug may be used only in thefirst reclosing interval socket. The instantaneous reclos-ing interval time will vary depending upon the recloser onwhich the control is used; the approximate values are:

CXE recloser ....................................................... .67 sec.

ME recloser ......................................................... .63 sec.

RVE, RXE, VWE, VWVE27, VWVE38, WE,WVE reclosers .................................................... .67 sec.

VSA12, VSA16, VSA20, reclosers ...................... .50 sec.

The INST reclosing interval plug must not be used withthe Type VSO recloser. No reclosing interval shorterthan 1⁄2 second should be programmed into the Type MEcontrol when it is used with the Type VSO recloser. A 1⁄2second reclose plug is available (ordered by KA1177ME-1). If an instantaneous (INST) plug is used for the firstreclosing interval, it will result in a 12 cycle reclosing time,which may be too short to permit arc deionization at thefault location.

Minimum-Trip ResistorCartridgesThe recloser minimum-trip current ratings are establishedwith the plug-in resistor cartridges in the center of the con-trol panel. The cartridges, labeled with their minimum-trip-current values, are identified for GROUND TRIP (onerequired), or PHASE TRIP (three required). All threephase-trip cartridges should have the same current rating.

All Kyle electronic reclosers, except VSA20, VS020, anddiscontinued Types ME and VSMT, use a yellow labelminimum-trip resistor cartridge. Blue label cartridges areused with 2000:1 sensing CTs in the higher current ratedVSA20 and VS020 reclosers and are not interchangeablewith yellow label resistors.Figure 9.

When dual-timing operation is programmed, the timingcharacteristic curve in Socket 1 always precedes thecurve in Socket 2. When single-timing operation is pro-grammed, the timing plug is installed in Socket 2 and thenumber of fast operations selector knob is set on zero.

Reset Delay SelectorFor temporary faults that are cleared before lockoutoccurs, reset timing starts after a successful reclosure(current is below minimum trip). The reset time is estab-lished by a timing plug similar to, but not interchangeablewith, the reclosing interval plug. The reset delay plug (Fig-ure 12) is located on the lower right hand portion of thecontrol panel. Times of 10, 15, 30, 45, 60, 90, 120, and180 seconds are available on a multiple setting plug andare determined by the position of the plug in the socketadapter (Figure 10). A 20 second, single-value plug isalso available.

Note: The selected reset delay time must be longer than thelongest reclosing interval of any load- or source-side pro-tective device with which the recloser is to coordinate.

CAUTION: Recloser misoperation. Socket 2must always be provided with a timing plug; other-

wise phase tripping is blocked and ground tripping maybe instantaneous. T218.1

Reset Timed from FirstTrip OperationThe Form 3A control can be converted to reset-timed-from-first-trip operation, if so desired, by removing ajumper on the tie board and moving a lead from the push-on tab labeled RECLOSE to an adjacent tab labeledHOME (Figure 13). However, under this reset mode, thetime selected must exceed the longest possible trippingand reclosing sequence that can be experienced. Mini-mum-fault currents (which provide the longest trippingtimes) must be considered.

Operating Switches andIndicatorsThe switches and indicators for manual operation andservice are grouped on the lower, light colored portion ofthe control panel (Figure 14).

Manual Control SwitchLocated in the center of the lower panel, the manual con-trol switch enables manual closing and tripping of therecloser. Moving the switch to TRIP opens the recloser,locks out the control, and disconnects the battery from thecontrol circuits. Moving the switch to CLOSE reconnectsthe battery, resets the control to home, and closes therecloser.

A cold-load pickup feature is built into this switch. Holdingthe switch in CLOSE will disconnect the no. 1 timing plugfor both phase and ground trip and set the control to oper-ate on the slower no. 2 plugs. While the switch is held inthis position, the control is still free to trip and lock out ifclosed into a fault. However, all operations to lockout willoccur on the no. 2 trip-timing plugs.

Ground-Trip Operation SwitchThe ground-trip operation of the control is disabled whenthis switch is set to BLOCK. Blocking ground-trip opera-tions is useful during known periods of three-phase loadunbalance and while performing single-phase testing orswitching.

Non-Reclosing/Normal ReclosingSwitch

To meet specific local safety requirements during startupor service restoration, the control can be set to blockreclosing after an automatic trip (one-shot-to-lockout-operation) by setting the operating mode switch to NON-RECLOSING. Returning this switch to NORMALRECLOSING after a successful reclose will ready thecontrol for its full programmed operating sequence.

Lockout Indicator Verification of control lockout consists of an indicator lampand a momentary double-throw toggle switch. In theLOCKOUT TEST position, the lamp will light if the controlis locked out; the LAMP TEST position verifies the condi-tion of the lamp.

Proper verification of the recloser status must includeexamination of both the control lockout indicator and avisual check of the position of the mechanical contactposition indicator on the recloser.

Battery TerminalsThese terminals provide a means for checking the condi-tion of the battery. Refer to the Battery Check Proce-dures in the Control Battery section in this manual.

Closing Coil Control FuseOn solenoid-operated reclosers, the fuse will open theclosing circuit to protect the potential closing coil in therecloser if closing cannot be accomplished due to lowclosing voltage. On motor-operated reclosers, the fuse isconnected in series with the closing circuit contactor in therecloser.

A Buss Type MDQ-3/8 amp, 250 volt fuse, manufacturedby Bussman Manufacturing is used and a box of fivespare fuses is supplied with each control. Fuses of similarratings by other manufacturers have slightly differentcharacteristics and should not be used for replacement.

Note: In 1988, Buss redesigned the MDL-2.5 amp fuse that isused on controls shipped with reclosers having "quick-close" mechanisms such as Type VSO reclosers. Thecharacteristics of the new single element MDL-2.5 fusedo not affect the application in the control. Buss will alsocontinue to manufacture the original dual element ver-sion of the fuse under the new designation of MDQ-2.5.The MDQ-2.5 amp fuse will be supplied with controls forthis application. Both the MDL-2.5 amp fuse and theMDQ-2.5 amp fuse are acceptable for this application.

14


IMPORTANT: The lockout indicator will only accu-rately reflect the state of the control. It does not monitorthe recloser mechanism and may not accurately reflectthe position of the recloser contacts.

IMPORTANT: Use only Buss Type MDQ-3/8 ampfuses. Until 1988, all Form 3A and most earlier controlswere supplied with Buss Type MDL-3/8 amp fuses.Buss has redesigned and changed the characteristicsof that fuse and it is no longer suitable for use on anyForm 3 or Form 3A control. Failure to use proper clos-ing coil control fuse will result in unnecessary fuse oper-ation and prevent the recloser from closing.

This control is used in conjunction with a Kyle electroni-cally controlled recloser. Installation instructions for therecloser are packed with the recloser. Refer to the appro-priate recloser installation manual when installing the con-trol and recloser.

Mounting the ControlThe Form 3A Type ME electronic recloser control can bemounted at any convenient, accessible location near, orremote from, the recloser.

1. For pole-mounted installations, this is normally nearthe base of the pole.

2. For substation installations, brackets are available asa mounting frame accessory for mounting the controlto the substation frame.

Limits on control cable length determine the maximumdistance between the control and recloser: up to 125 feetfor solenoid-operated reclosers RVE, RXE, VWVE27,VWVE38, WE, WVE; up to 35 feet for motor-operatedreclosers CXE, VSA12, VSA16, VSA20, and VSML.

Grounding the ControlThe control cabinet must be grounded. A grounding con-nector on the underside of the cabinet will accommodateno. 14 solid through no. 4 stranded conductors. (Figures15 and 16). Be sure to follow all locally approved ground-ing procedures when installing the control. Suggestedmethods for grounding the control are shown in Figures17 and 18.

The installation must meet the following requirements:

1. The recloser and transformer are protected with light-ning arresters.

2. The transformer tank is grounded.

3. The recloser head is grounded.

4. Secondary cables must be shielded or Triplex cables.

Note: If the control is mounted on a recloser frame whichitself is grounded, a separate lead from the cabinetto earth ground is not required but may be added.

ELECTRICAL CONNECTIONS

Control CableA 7 ft. cable is furnished as standard with the control-recloser package. This length is sufficient for most sub-station mounting frame installations. For otherinstallations, cable lengths as specified on the order areprovided.

The cable is fabricated with connectors which mate withthe female receptacle of the recloser on one end and themale receptacle of the control on the other.

Note: The control cable must be supported along its length toprevent repeated movement due to wind or other out-side forces which can damage the cable.

Shielding and Surge Protectionof Remote CablesAll remote operation and control monitor leads should beprotected within shielded cables. This is particularlyimportant if the remote cables are routed near othercables or devices that emit strong magnetic fields. Thecable shield must be grounded at the Form 3A controlonly, see Figure 19.

Note: In order to protect a remote device(s) from high-voltagesurges, all remote operation and monitor leads must beprotected with metal oxide varistors (MOV's), see Figure 19.Use Harris V320LA40B varistors, (320 Vac, 160 J), orequivalent.

Customer Connections TerminalStrip

All Form 3A controls require 120 Vac auxiliary power tooperate the battery charger and energize the control cab-inet heater; both are standard features of the control.

Auxiliary power connections and connections for remoteoperation of certain accessories are made on a 14 pointterminal strip mounted vertically on the back panel of thecontrol. Figure 20 shows two partial detail views of the ter-minal strip to indicate the customary connection terminalsfor the various accessories. However, deviations mayoccur to accomodate certain combinations of acces-sories. All terminals for required connections are clearlymarked.

The minus side of the 24 Vdc control circuit is grounded tothe cabinet at the input cable receptacle card in the bot-tom of the cabinet by a white jumper lead connectedbetween tabs GND and BATT-. When an external dcpower source accessory is used instead of the battery,remove the jumper to make sure there is no interactionbetween station ground and earth ground.

Note: A 27 ohm resistor on the receptacle card, in series withthe grounding jumper lead, will limit the short-circuit cur-rent to nondestructive levels in case of momentary acci-dental grounding of the plus side of the circuit. Asustained short will cause the resistor to overheat andeventually burn out. This condition, however, will notaffect control operation.

Control / RecloserInterchangeabilitySince a temperature-regulated, 120 Vac, potential-typebattery charger is a standard feature of the Form 3A elec-tronic control, the battery charger is not included as astandard feature of the companion electronically con-trolled reclosers. It is, however, available as a factoryinstalled accessory for these reclosers. Care must beexercised when interchanging "new-style" controls (Form3A) and "old style" controls (Form 3) with "new style"reclosers (without battery recharger) and "old style"reclosers (with battery charger as standard) to make surethat each combination has an operational battery charger.

The Form 3A control, or the Form 3 control equipped witha battery charger accessory, is compatible with all old-and new-style reclosers provided 120 Vac power is avail-able at the control.

If 120 Vac is not available at the control, the Form 3A con-trol can be made compatible with any old-style recloser bychanging the connections on the input receptacle card asshown in Figure 21 to connect the battery charger in therecloser to the control.

If 120 Vac is not available at the control, the new-stylerecloser must be equipped with its battery charger acces-sory to be compatible with the Form 3A control. The com-bination of a Form 3 control, without the battery chargeraccessory, and a new-style recloser does not have anoperational battery charger. To make this combinationcompatible, either the control or the recloser must beequipped with its battery charger accessory (dependingon whether 120 Vac is or is not available at the control).

Testing with Type MET TesterThe Kyle Type MET Electronic Recloser Control Tester(Figure 23) has been designed specifically for testingForm 3A controls. The MET Tester is completely self-con-tained, includes all necessary metering and interconnect-ing cables, and is capable of performing all requiredchecks and tests from a simple verification of operation toa complete verification of operation of all operatingparameters. Operating instructions for the Type METTester are contained in Service Information S280-76-1.

If an MET Tester is not available, the following test pro-cedures, ranging in complexity from a simple check ofcoordinated control-recloser operation to a verification ofthe various control settings, may be performed:

• For a simple check of coordinated control-recloseroperation, the output of a soldering gun (with the tipremoved) connected across a minimum-trip resistorwill provide a signal of sufficient strength to simulate afault current and operate the control. Refer to the Sol-dering-Gun Test section in this manual.

• To verify minimum trip, t iming, and operatingsequence, an equivalent test current which simulatesthe output of the sensing CTs can be introduceddirectly into the control. Refer to the Testing withSimulated Current section of this manual.

• To verify the control settings and check the sensingCTs, a variable, low-voltage test current simulatingfault conditions can be passed through one phase ofthe recloser. Refer to the Testing with Low-Volt-age Current section of this manual.

Testing an Installed ControlA recloser control can be taken out of service for testingand placed back in service without deenergizing itsrecloser and interrupting the system. However, during thetime the control is out of service, system fault protectionis lost.

To Remove Control from ServicePrior to testing, changing plug-in components, performingcontrol maintenance, making program changes, or bat-tery replacement on an in-service control, the followingsteps must be taken to prevent possible recloser misop-eration.

1. Switch Ground Trip Block switch to BLOCK.

2. Disconnect control cable from control.

3. De-energize potential battery charger, by opening thebattery charger fuse block switch (shown in Figure 4.)

4. Operate the Manual Control switch to OPEN.

5. Unplug the control battery.

For shop testing, the closing solenoid voltage can besupplied by back-feeding a transformer with a low-siderating equal to the voltage rating of an available powersource and a high-side rating equal to the voltage ratingof the recloser. This procedure is not to be used onreclosers equipped with the low-voltage closing acces-sory, see Figure 25. Make sure the solenoid coil operatingvoltage is maintained at the recloser bushings during thetwo-to-three cycle interval the closing coil is energized. Ingeneral, a 75 kVA transformer of the proper voltage ratingwith an impedance drop of about 3% will be satisfactory.The source impedance must also be reasonably low. The

closing coil requirement is approximately 200 kVA duringthe two-to-three cycle closing operation.

Electrical Closing - CXE, VSA, VSO,and VSML ReclosersCXE, ME, VSA, VSO, and VSML reclosers utilize a motor-operated closing mechanism which is energized from a230 Vac power source; no high-voltage is required.

Manual Closing - Solenoid-OperatedReclosersIf high-voltage for operating the closing solenoid of RVE,RXE, VWE, VWVE27, VWVE38, WE, and WVE reclosersis not available, manual closing can be substituted forelectrical closing; however, not all control settings can bechecked since manual closing is not synchronized withthe closing coil control circuit in the control.

To manually close the recloser:

1. Remove the closing tool port cover and gasket fromthe side of the recloser head casting.

2. Insert the KA90R T-handled tool (available as anaccessory) into the port, engaging the pin on the clos-ing shaft. (Figure 26).

3. Close the recloser by placing the yellow operatinghandle (under the sleet hood) into the up or CLOSEDposition and turning the closing tool one-quarter turnclockwise.

4. After each trip operation, about 1⁄2 second will elapsewhile the closing solenoid plunger is moving upward toreset the main toggle latch.

5. After the main toggle latch resets, the recloser can beclosed again by operating the manual closing tool.

6. Replace the gasket and port cover on the recloserhead after testing has been completed.

7. Reinstall the control closing coil fuse.

Soldering-Gun TestThe output of a soldering gun (Weller Model 550 or equiv-alent) will produce a signal of sufficient strength to simu-late a fault and check recloser-control operation. Tosolder-gun test a control:

1. Set the Non-Reclose/Normal Reclose switch on thecontrol to NORMAL reclosing and the Ground TripBlock switch to NORMAL.

2. Move the manual control switch on the control panel toTRIP, to open the recloser contacts.

3. Remove the tip from the posts of the soldering gun byloosening the hexagonal locking nuts.

4. Connect a short clip lead to each post and connect thesoldering gun across the Phase A minimum trip resis-tor as shown in Figure 27.

5. Move the manual control switch on the control panel toCLOSE. The recloser should close.

6. Energize the soldering gun by depressing and holdingthe trigger until the recloser trips.

7. Immediately release the trigger to prevent instantan-ious trips on succeeding reclosings.

8. When the recloser recloses, again energize the sol-dering gun and repeat Steps 5 and 6 until the controllocks out. Count the number of fast and delayed tripoperations and compare the count with the control set-tings. Verify lockout with the switch on the operatorpanel.

9. Repeat on Phases B and C and Ground if desired.

WARNING: Explosion Hazard. Excessive Con-tact Arcing. Do not use the manual closing tool to

close an oil-insulated energized recloser. Closing anenergized oil-insulated recloser with a manual closingtool can cause excessive contact arcing, rapid build-upof gas within the equipment, and possible explosion thatcan cause death, severe personal injury, and equip-ment damage. T203.2

Testing with Simulated CurrentThe Form 3A electronic recloser control continuouslymonitors line current conditions with three wye-con-nected 1000:1 ratio current transformers mounted inter-nally on the source-side bushings of the recloser. TheseCTs are connected directly to three wye-connectedphase minimum-trip resistors on the control panel. Afourth resistor (ground trip) is connected in the CT neutralto monitor zero-sequence current flow.

The current through any one of the minimum-trip resistorsis 1/1000 of the line current. Therefore, if 1/1000 of theline current is applied directly to the resistor, the controlwill operate as if line current was flowing through the CTprimary and one milliamp of test current will be equivalentto one amp of line current.

Note: The above applies to all but the VSA20, VSO20 and thediscontinued Type ME and VSMT reclosers. Thesehigher continuous-current-rated reclosers use 2000:1ratio sensing CTs and special blue label minimum-tripresistors. For Type VSA20 AND VSO20 reclosers, onemilliamp of test current is equivalent to two amps of linecurrent. When testing controls equipped with blue labeltrip resistors, double the milliamp reading to obtain theequivalent line current.

Test EquipmentA test circuit to produce a variable output in equivalentamps is shown in Figure 28. This circuit will provide afairly complete test of the control and recloser. All partsare standard and can be purchased through any elec-tronics supply outlet.

Note: High voltage is required to operate the closing solenoidof Type RVE, RXE, VWE, VWVE27, VWVE38, WE, andWVE reclosers, unless they are equipped with the lowvoltage closing accessory. A 240 Vac power source isrequired to operate the motor of CXE, VSA, VSO, andVSML Reclosers. Various closing schemes are dis-cribed in the Closing the Recloser section.

Test Procedure

Coordinated Operation of Control andRecloser

1. Make certain that closing power is available at therecloser.

A. On solenoid-operated reclosers, move the yellowmanual operating handle (located under the sleethood) to the up position.

B. On motor-operated reclosers, move the TRIP-RESET lever or rod (located in the recloser opera-tor cabinet) to RESET.

2. Set the operating mode switch on the control to NOR-MAL reclosing and the ground trip switch to NOR-MAL.

3. Move the manual control switch on the control panelto CLOSE. The recloser should close.

4. Move the manual control switch on the control panelto TRIP. The recloser should open.

Figure 28.Simulated Current Test Circuit.

Minimum-Trip CurrentThe minimum-trip current test should be performed on afast time–current curve operation. The test will producemisleading results if the control is operating on a delayedTCC curve.

Note: If the control is equipped with the KA418ME7 sequencecoordination accessory, refer to Service InformationS280-75-37 for additional information.

To test minimum-trip current:

1. Move the manual control switch to CLOSE to close therecloser.

2. Connect the output of the test circuit across the PhaseA minimum trip resistor.

3. While holding fault switch S1 on the tester closed,slowly raise the test current from zero and note themeter reading when the recloser trips. This reading inmilliamps should correspond to the trip resistor valuein amps. For example, a 280 amp resistor should tripat 280 mA.

4. Release S1 before the recloser automatically reclosesto prevent instantaneous trips on succeeding reclos-ings.

5. Repeat steps 1 through 4 for the Phase B, Phase C,and Ground trip resistors.

Trip TimeThe trip times of the fast timing plugs (Sockets 1 and 1 ),are ordinarily too fast to check with a stopwatch with anyaccuracy. However, the delayed timing plugs (Sockets

2 ) can be checked. To check the delayed timing plugs:

1. Move the manual control switch to TRIP to open therecloser.

2 Remove the RESET DELAY plug from the controlpanel.

3. Connect the output of the test circuit across the PhaseA minimum trip resistor.

4. While holding Fault switch S1 closed, adjust the out-put to produce an equivalent test current of at least150% of minimum trip. For example, a 420 mA testcurrent for a 280 amp resistor.

5. Release S1 and move the manual control switch toCLOSE to close the recloser.

6. Close S1; the recloser should trip in a very short time.

7. Release S1 immediately and allow the recloser toclose automatically.

8. Repeat Steps 6 and 7 for all fast operations toadvance control operation to the delayed time-currentcurve.

Note: The number of fast operations is determined by the setting of GROUND TRIP SOCKET 1and PHASE TRIP SOCKET 1 switches in the upper left corner of the panel.

9. Close S1 and, at the same time, start a stopwatch.

10. When the recloser trips, stop the watch and releaseS1. Compare the time to the time at 150% of minimumtrip on the published time–current curve for the timingplug being checked. For example, a B plug will clear inabout 2.8 seconds at 150% minimum trip.

11. Repeat Steps 9 and 10 to lockout.

12. Repeat Steps 3 through 11 for the GROUND TRIPTIMING Plug 2 .

Reclosing TimeTo check reclosing time (the open interval of the recloserbetween trips):

1. Move the switch to CLOSE to close the recloser.

2. With the tester output connected across any one ofthe minimum-trip resistors and adjusted to produce aneqivalent test current of at least 150% of the minimumtrip rating, close Fault Switch S1.

3. When the recloser trips, release S1 and start timingthe interval the recloser is open, stopping when therecloser recloses. The time should correspond to thefirst RECLOSING INTERVAL DELAY plug setting.

4. Repeat Steps 2 and 3 to check the timing of the sec-ond and third RECLOSING INTERVAL DELAY plugs.

5. Replace the RESET PLUG on the control panel.

Reset Time – Timed from SuccessfulReclosureReset timed from a successful reclosure is standard onthe Type ME Form 3A control. To check the reset time:


2. With the tester output connnected across any one ofthe minimum-trip resistors and adjusted to produce anequvalent test current of at least 150% of the min-imun-trip rating, close Fault Switch S1.

3. When the recloser trips, release S1 and wait for therecloser to reclose automatically.

4. Start timing when the recloser closes and stop whenthe control resets automatically as indicated by anaudible clicking as the sequence relay returns to homeposition.

5. The elapsed time should correspond to the setting ofthe RESET DELAY plug.


26

Reset Time-Timed From First TripOperationThe Form 3A control can be converted to reset-timed-from-first-trip operation as described in the Reset DelaySelector section.

To check the timing of this reset mode:


2. With the tester output connected across any one ofthe minimum-trip resistors and adjusted to produce anequivalent test current of at least 150% of the mini-mum-trip rating of the resistor, close Fault Switch S1.

3. When the recloser trips, release S1 and start timing.

4. Continue timing after the recloser automaticallyrecloses until the control resets automatically as indi-cated by an audible clicking as the sequence relayreturns to its home position.

5. The elapsed time should correspond to the setting ofthe RESET DELAY plug.

Operation of the Non-ReclosingSwitchThe non-reclosing switch provides one-trip-to-lockoutcapability without disturbing the normal operatingsequence of the control. To check its operation:

1. Move the non-reclosing switch to NON-RECLOSING.


3. With the tester output connected across any one ofthe minimum-trip resistors and adjusted to produce anequivalent test current of at least 150% of the mini-mum-trip rating of the resistor, close Fault Switch S1.

4. The recloser should trip once and not reclose. Thecontrol should indicate lockout position when theLOCKOUT TEST switch is operated.

Testing with Low-VoltageCurrentThe Form 3A recloser control-with its recloser-can betested with a variable low-voltage current passing throughone phase to simulate fault conditions.

Test Equipment RVE, RXE, VWE,VWVE27, VWVE38, WE, AND WVEReclosers

A test circuit for these solenoid-closed reclosers is shownin Figure 25. The following equipment is required for therecommended test setup:

Note: Solenoid-closed reclosers equipped with a 120- or 240-Vac low-voltage closing coil accessory can be tested asshown in Figure 29.

• Variable Autotransformer T1, 230 volts, 20 amps.

• Low-Voltage transformer T2 to simulate fault conditions.

Ratio and size will depend upon the maximum currentto be used. The recloser presents a low impedance tothe transformer, so secondary voltage must be onlyhigh enough to force the required current through thesecondary of the transformer and the recloser.

Note: An alternative method of providing the necessarycurrent through the transformer is shown in Figure30.

• High-Voltage T3 to operate the closing solenoid. Referto the Closing the Recloser section for high voltagetransformer requirements.

• Ammeter with a rating based on the level of test current.

• Current-actuated timer or stopwatch.

Test ProcedureTest Current Applied to Phase A

1. Assemble and connect the equipment as shown inFigure 25, which shows the test current being appliedto Phase A, the phase nearest the sleet hood.

2. Verify that closing power is available at the recloser.

3. Move the yellow manual operating handle, locatedunder the sleet hood, to the UP position.

4. Set the Non-Reclosing/Normal Reclosing switch onthe control panel to NORMAL RECLOSING and theGround Trip switch to BLOCK.

5. Move the manual control switch to CLOSE. Therecloser should close, indicating correct operation ofthe control and recloser.

6. Move the manual control switch to TRIP. The reclosershould open, verifying the electrical operation of thetrip solenoid and the mechanical operation of the tripmechanism.

Test ProcedureTest Current Applied to Phase B and C

1. De-energize the high-voltage closing source andclose the recloser manually before testing phase Band C. Refer to the Manual Closing procedure in theClosing the Recloser section of this manual.


3. Move the yellow manual operating handle, locatedunder the sleet hood, to the UP position.




Test Equipment CXE, VSA, VSO, andVSML ReclosersA test circuit for these motor-operated reclosers is shownin Figure 29. Since these reclosers require only a 240 Vacsource for closing, High-Voltage Transformer T3 and itsassociated protective cage is eliminated, but all otherequipment is the same as the test equipment shown inFigure 25.

Test Procedure

Minimum-Trip CurrentThe minimum-trip test should be performed on a fasttime–current curve. The test will produce misleadingresults if the control is operating on a delayed time–current curve.

Note: If the control is equipped with the KA418ME7 sequencecoordination accessory, refer to Service InformationS280-75-37 for additional information.

To test the minimum-trip current:

1. Move the manual control switch to CLOSE to closethe recloser.

2. With the test circuit connected to Phase A, energizeT1, slowly raise the test current from zero, and notethe meter reading when the recloser trips. This read-ing should correspond to the minimum current ratingof the Phase A trip resistor.

3. After the recloser trips, turn T1 back to zero and movethe manual control switch to TRIP to lockout therecloser.

4. Repeat Steps 1 through 3 for Phase B and Phase Ctrip resistors.

5. To check the minimum ground-trip resistor, place theground-trip switch to NORMAL and repeat Steps 1through 3.

Note: The single-phase fault test current will appear as aphase-to-ground fault to the control. Therefore, whenchecking ground settings, jumper the minimum-trip resis-tor of the energized phase to block phase-trip operations.

Trip TimeIf an electrically operated timer is used, both the fast anddelayed time–current curves can be checked; however,the trip times of the fast timing plugs (sockets 1 and 1 )are ordinarily too fast to check with a stop watch with anyreasonable accuracy. To check the trip times:

1. Move the manual control switch to CLOSE to closethe recloser.

2. With the ground-trip switch set on BLOCK, connect ashort clip lead across the minimum-trip resistor of thephase being tested to prevent tripping of the recloserwhile the test current is being adjusted.

3. Energize T1 and adjust the current for 150% of mini-mum-trip rating.

4. Without disturbing the setting of T1, deenergize T1.

5. Remove the jumper from across the minimum-tripresistor.

6. Keeping T1 at the desired setting, energize T1 andrecord the tripping times as the recloser operatesto lockout. These times should correspond to thetimes at 150% of minimum-trip on the publishedtime–current curves for the timing plugs beingchecked. Delayed times can be measured with a stop-watch.

7. To check the ground-trip timing plugs, place theground-trip switch to NORMAL and repeat Steps 1through 6.

Note: The single-phase fault test current will appear as aphase-to-ground fault to the control. Therefore,when checking ground settings, jumper to the mini-mum-trip resistor of the energized phase to blockphase-trip operations.

8. Return the ground-trip switch to BLOCK after the testhas been completed.


IMPORTANT: Before checking the Phase B andPhase C trip resistors on solenoid-operating reclosers,de-energize the high-voltage closing source and closethe recloser manually. Refer to the Manual Closing ofthe Closing the Reclosers section of this manual.

Reclosing TimeTo check reclosing time, which is the open interval of therecloser between trips:


2. Energize T1 and adjust T1 to produce a current inexcess of the phase minimum-trip value.

3. When the recloser trips, time the interval until therecloser recloses.

4. Time the second and third open interval in the samemanner.

5. The times should correspond to the first, second, andthird RECLOSING INTERVAL DELAY plug settings,respectively.

Reset Time Timed from SuccessfulReclosureReset timed from successful reclosure is standard on theType ME Form 3A control. To check the reset time:


2. With T1 adjusted to produce a current in excess of theminimum-trip value, energize T1.

3. When the recloser trips, deenergize T1 and wait forthe recloser to reclose automatically.

4. Start timing when the recloser recloses and stop tim-ing when the control resets automatically as indicatedby an audible clicking as the sequence relay returns tothe home position.

5. The elapsed time should correspond to the setting ofthe RESET DELAY PLUG.

Operation of the Non-ReclosingSwitchThe non-reclosing switch provides one-trip-to-lockoutcapability without disturbing the normal operatingsequence setting of the control. To check its operation:

1. Set the non-reclosing switch to NON-RECLOSING.


3. With T1 adjusted to produce a current in excess of theminimum-trip value, energize T1.

4. The recloser should trip once, and the control shouldindicate lockout position when the LOCKOUT TESTswitch is operated.

Testing RVE, RXE, VWE, VWVE27,VWVE38, WE, and WVE Reclosers withManual ClosingTesting procedures for minimum-trip current, time–currentcurve time, reset time timed for successful reclose, resettime timed from first operation, and operation of the non-reclosing switch are the same as testing per the Testingwith Simulated Current procedure section except forType RVE, RXE, VWE, VWVE27, VWVE38, WE, and WVEreclosers. These reclosers will not close automatically.They must be manually closed after each trip operation.

For the Manual Closing Procedure, refer to the Closingthe Recloser section of this manual.

When testing reclosers with manual closing, the followingadditional precautions must also be observed:

1. Since manual closing is not synchronized with theclosing coil control circuit in the control, the controlfuse will blow if manual closing is not performed withinthe reclosing interval. To prevent damage, remove thefuse during testing.

2. If the control is operating in the reset-after-first-tripmode, the reset-delay plug may be removed from thecontrol for all testing except reset time timed from suc-cessful reclose and reset time timed from first opera-tion. If the reset-delay plug is not removed, the controlmay reset before a test sequence is completedbecause of the possible delays between trip opera-tions when manual reclosing is used.

3. The variable autotransformer must be kept energizedat the proper setting while the recloser is closed man-ually. Setting it properly before manual reclosing is ini-tiated assures accurate timing values.
