INTRODUCTIONService Information S28O-75-2 covers basic maintenanceinstructions for the Type ME electronic control. The manualincludes a general description of the control, its operatingprinciples and instructions for periodic inspection and testing.Service parts lists along with ordering information are includ-ed in Appendix IV.

An introduction to the Form 3A, Type ME, electronic controlis available on video cassette (KSPV3); in this program thefunction of all standard operating and programming featuresis explained.

The factory service department offers maintenance trainingcourses for Type ME controls. These classes, taught by ex-

perienced service technicians, are held at the factory’s in-housetraining facility. For additional information, contact your sales engi-neer.

DESCRIPTIONThe Kyle Type ME electronic recloser control (Figure 1 ) is com-prised of a number of programmable, solid-state electronic circuitsthat perform the command functions involved in automatic recloseroperation. It is used to operate all Kyle electronically controlledreclosers.

A swing-out front panel contains the programming and operatingelements of the control (Figure 2). The upper, black portion

4

Figure 3.Tie board on back of front panel mounts the individual printed circuit boards.

Type ME Electronic Recloser Control

88938KMA

of the front panel contains the plug-in components and settingknobs for programming automatic recloser operation. Theswitches and indicators used for manual operation and serviceare grouped on the bottom, light portion of the panel.

The front panel is backed by a printed-circuit tie board whichsupports and interfaces the plug-in circuit boards with otherrelated circuit components (Figure 3). Program-altering,remote control, indicating, and general convenience acces-sories can be added to further expand and enhance the appli-cation capabilities of the control.

Line current flowing through the recloser is sensed by threeinternally mounted bushing-current transformers, one on eachphase. When the phase current, or the zero-sequence (ground)

current, exceeds its programmed minimum-trip value, theelectronic control initiates the programmed sequence ofrecloser tripping and reclosing operations. If the fault is tempo-rary, the control ceases to command recloser operations aftersuccessful reclose, and the control resets to the start of itsoperating sequence after a preset time delay. If the fault ispermanent, the control performs its complete programmedsequence of recloser commands and locks out with the reclos-er open. Once locked out, the control must be manually resetto the start of its operating sequence which simultaneouslycloses the recloser.

Factory-calibrated timing plugs establish the time-currentcharacteristics for both phase and ground tripping. Two sets ofindividual timing curves provide dual timing for both phase andground.

OPERATIONSince the understanding of the terminology and the operat-ing sequences of an electronically controlled recloser isimportant to the rest of this maintenance manual, examplesof typical operating sequences of an electronically controlledrecloser under permanent fault (Figure 4) and temporaryfault (Figure 5) conditions are given. The definition of theterms and callouts used in Figures 4 and 5 are:• Minimum Trip—Minimum trip is usually set at greater

than 2 times (200%) the maximum expected load currentto help prevent nuisance tripping on inrush currents, whilestill being sensitive to low level faults.

• Over-Current—Any current that exceeds the minimum-trip level of the control.

• Permanent Fault—Any over-current condition that per-sists through the operating sequence of the control.

• Temporary Fault—Any over-current condition that doesnot persist through the operating sequence of the control.

• Home Position—Position of sequence relay immediately after areset operation of the control. Reset operation can be eithermanual, by moving the Manual Control Switch to “CLOSE”, or automatic, after a temporary fault.

• Lockout—Sequence-relay position when over-current is not cleared before the operating sequences of the control are exceeded; control and recloser are tripped and held open until manually reset with the Manual Control Switch, or remotely with one of the remote close accessories.

• TCC—Time-Current-Characteristic-Curve.• Reclose Interval—Time-delay interval for each reclosing opera-

tion within the operating sequence of the control.• Fault Level Current—Any current that exceeds the minimum-

trip level of the control.• Normal Load—Any current below the minimum-trip level of the

control.

Figure 6.Functional block diagram of Type ME control.


A functional block diagram of the control operation is shownin Figure 6. Line current conditions are continuously monitoredby the three bushing-type current transformers in the recloser.output from these transformers is fed to the trip network in thecontrol, which includes: the minimum-trip resistors, isolationtransformers, and rectifier circuits.

If current remains above the minimum-trip level, the tripping—reclosing sequence of fast and delayed operations is repeat-ed as programmed to lockout.

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

The overcurrent signal is integrated with time on the charac-teristic curve of the timing plug in Socket 1 to produce the sig-nal which energizes the trip circuit. Energizing the trip circuitconnects the battery to the trip solenoid, tripping the recloser.Simultaneously, the sequence relay advances to energize thefirst reclosing interval-delay plug. Upon expiration of thisreclosing interval delay, a closing signal, from the control, clos-es the recloser, and the sequence relay sets up the circuitry forthe second fast trip operation.

If the overcurrent is cleared before the operating sequencereaches lockout, the reset-delay circuit starts timing when therecloser closes into the unfaulted line. When the reset-delayplug times out, the sequence relay is reset to the start or“HOME” position and the control is ready for another two-fast,two-delayed trip-operating sequence. However, should thefault restart before the reset plug times out, the control willcontinue its operating sequence, where it left off last, and thereset-delay timing will be erased.

Ground-fault sensing and tripping operations occur exactlythe same as phase-fault sensing and tripping, except thatzero-sequence (ground) current is sensed instead of phasecurrent. The ground-fault circuitry includes its own minimum-trip resistor, fast and delayed trip-timing plugs, and number offast operations setting. Reclose and reset intervals and opera-tions to lockout are common for both phase-trip and ground-trip modes of operation.

PERlODIC FIELD INSPECTlON AND MAINTENANCEPeriodic inspection of the ME control should include these proce-dures:

1. Remove control from service (if connected to an in servicerecloser):A. Switch Ground Trip Block switch to “BLOCK”. B. Disconnect control cable from control.

2. Check the outer surface of the control cabinet for paintscratches. Touch up any paint scratches to maintain the cabi-net condition.

3. If the second entrance hole in the bottom of the cabinet is notused, be sure that the hole plug is secure in the bottom of thehousing to maintain its weatherproof design.

4. Inspect the gasketing. Check the control interior for any mois-ture or foreign matter. Repair or correct if necessary.

5. Check that the timing plugs, reset and reclosing intervaldelays, and minimum-trip resistors are firmly in their sockets(Figure 2).

6. Swing open the front panel. Check to see that all leads to tie-board terminals are secure (Figure 7).

CAUTION: Shorting battery positive to batterynegative at the battery test terminals will cause per-

manent damage to the control. The control will be inoper-ative and possible misoperation (unintentional operation)of the recloser may result.

!

CAUTION: In order to prevent possible, misoper-ation (unintentional operation) of the recloser, the

control must be removed from service prior to performingany maintenance, testing or programming changes.

!

WARNING: High voltage. Contact with high volt-age will cause serious personal injury or death.

Follow all locally approved safety procedures when work-ing around high voltage lines and equipment.

7. Check battery voltage. Three battery test terminals in thelower right corner of the panel (Figure 2) are used to checkbattery voltage, quiescent drain, and charging rate. Referto the “Battery Maintenance” instructions in this manual.

The left-hand pair of terminals (V) are connected directlyacross the battery output to check battery voltage. The redterminal (far left) is positive (+). The output voltage of a fullycharged battery will normally be 26-28-volts. If lower, refer

to the “Detailed Circuit check—Battery Charging” and/or“Battery Maintenance” section of this manual.

If necessary, recharge the battery, as detailed in the“Battery Maintenance” section.

8. Make sure circuit boards are secure in their receptacles.Examine wiring between transformers and tie boards to see ifconnections are in order. Close front panel and secure firmlywith fasteners.

9. Check control battery charging rate before returning thecontrol/recloser to service; see the “Battery Maintenance”section for details on charging rate testing.

NOTE: The servicing procedures outlined in this manual are for astandard Type ME Form 3 and Form 3A control and do not includethe operational checks of any of the accessories that may beattached. In some cases the accessories may modify the standardoperating characteristics of the Type ME control. Refer to catalogbulletin 280-75 for accessories furnished and/or Accessory opera-tion, Testing, and Installation manuals listed in Appendix lll of thismanual.

10. Return control to service:A. Check battery to ensure that it is properly connected.B. Move Manual Control Switch to match position of reclos-

er (open or closed).C. Reconnect control cable to control.D. Switch Ground Trip Block switch to “NORMAL”.

SERVICINGCircuit LogicLine current conditions are monitored continuously by threebushing-current transformers in the recloser, one on eachphase. The current transformers are connected to the control-phase matching transformers in a typical “WYE” to “WYE” con-figuration. Zero-sequence current is derived from the vector sumof the phase currents and fed to a fourth ground matching trans-former.

The minimum-trip resistors calibrate the overall recloser tripcurrent by diverting a portion of the recloser current from thecontrol matching transformers.

The four matching transformers isolate the various signalsfrom each other and deliver an ac voltage proportional to therecloser-line current to the phase-trip No.1 end ground-trip No.1 boards.

S280-75-2

Figure 9.Diagram of Form 3A tie board showing plug-in circuit board location. Form 3 tie boards are similar (see Figure 18), except some ofthe terminals are missing or in a slightly different location.

From this point, phase- and ground-trip signals are verysimilar, and only phase signals will be described.

The phase-trip No. 1 board circuitry, consisting of a three-phase full-wave rectifier, which converts the ac input signalfrom three phase to a single do signal. The do signal isapplied to the phase-trip No. 2 board which measures the dolevel, and determines whether a fault current exists at therecloser.

If the load current conditions are in the fault region, the mini-mum-trip portion of the phase-trip No. 2 board switches on, allow-ing the time-current curve circuits to start their programmed timedelay. The time-current curves are driven by the same do voltageoutput of the phase-trip No. 1 board, and as a result higher fault-current levels will result in a shorter time delay before tripping.

Figure 10.Battery-charging board,

After the timing plugs have completed their cycle, the outputboard is triggered. The output board applies a 24-Vdc signal tothe recloser trip coil, the control counter, and the controlsequence relay. The output board is switched off when therecloser “a” contact de-energize the circuitry, including thesequence relay. The sequence-relay rotary contacts thenadvance to the next position in the tripping and reclosing cycle.

The recloser “b” contacts then close, connecting batterypower to the reclose intervals of the control which provides atime delay for reclosing the recloser. The rotary close solenoidis then energized through the recloser “b” contacts, the controlfuse, and the reclose portion of the control circuitry. Thismechanically closes the closing contactor in the recloser—allowing the closing solenoid to be energized.

After closing the recloser “b” contact opens, this removes dopower from the entire closing circuit.

The automatic reset portion of the Form 3A control is ener-gized by the sequence relay and the recloser “a” contact; if afault does not exist on either phase or ground trip, reset timingis initiated (unless connected to time after first trip). If a faultexists on either phase or ground, the reset timing is erasedand is blocked for the duration of the fault. For Form 3, resettiming begins after the first tripping operation. Should the resettime-delay operate before the recloser has locked open, thesequence relay will return to the starting position and a newsequence of operations will begin.

NOTE: F3 controls can be updated, with the addition of the KA304ME,to duplicate the automatic reset mode of a F3A control.

The Form 3A control battery is charged by the ac input(120-or 240-Vac) to the control. The ac input is applied througha current limiting resistor and isolating transformer to the bat-tery charging board. The battery charging board converts theinput to dc and supplies charging current to the control battery.on Form 3 controls, the battery is charged by bushing currenttransformers on the recloser unless equipped with an accharging accessory. on motor operated reclosers, the ac sup-ply to the motor also supplies power to the Form 3 batterycharger.

Plug-in Circuit Boards - FunctionThe ME control contains a total of eight plug-in circuit boards onwhich are assembled the bulk of its operating circuits. Theboards and their function will be discussed individually in theorder they appear on the tie board, starting with the bottomboard.

BATTERY-CHARGING BOARDThe lowest board in the rack is the battery-charging board(Figure 10). Prior to serial number 50070 controls were equippedwith a fixed rate potential charging board (MEA 388-1 ) as stan-dard equipment. After serial number 50070 a temperature regu-lated battery-charging board (MEA 1172) has been supplied asstandard. !

The fixed rate charging board consists of a full-wave bridgerectifier, a capacitor, a reference zener diode and some resis-tors. The resistors control the charging rate into the battery, fromthe zener supply voltage.

The temperature regulated battery-charging board also makesuse of a full-wave bridge rectifier, a capacitor, and a zener diode(used to regulate voltage). In addition a temperature sensitivethermistor is added to regulate the bias over a pair of transistors.These transistors are used in the circuit output to regulate thecharging rate, in response to temperature. Several resistors areused in the transistor bias circuit; and one resistor is used to limitthe maximum charging rate. A diode is placed in the output toprotect the circuit from reverse bias. ‘

Energy for either battery-charging board comes from the 120-or 240-Vac source,through current limiting resistance and apotential transformer.

CAUTION: Do not replace a MEA 388-1 boardwith a MEA 1172, or vice-versa. A MEA 388-1

board will be damaged if replaced ffor a MEA 1172. AMEA 1172 will not provide adequate charging current ifreplaced for a MEA 388-1

PHASE-TRIP NO. 1 BOARD The second board from the bottom is the phase-trip No. 1board (Figure 11). It has three full-wave diode sets, one foreach phase, along with a loading resistor for each phase.This board also has the beginning circuits for the minimumtrip function.

PHASE-TRIP NO. 2 BOARDThe phase-trip No. 2 board (Figure 12) carries the remaining cir-cuits for minimum-trip and the wave-shaping circuits for the timingplugs. There are two tabs on the phase-trip No. 2 board for theForm 3 and 3A control. one tab is labeled minimum-trip (MIN.TRIP)* and is battery plus for normal line currents and switches tobattery minus for fault currents; the second tab marked (DIR.BLOCK)* is an inactive tab at this time.

* In early Form 3 boards, these tabs may not be labeled.

GROUND-TRIP NO. 1 AND NO. 2 BOARDSThe next two boards up, ground-trip No. 1 and No. 2 (Figures 13and 14), are like the corresponding phase-trip boards, except thatthe ground-trip No. 1 board has only a single input diode bridge forground current. These boards carry almost the same parts andsame configurations as the corresponding phase boards.

OUTPUT BOARDThe output board (Figure 15) of the control has another doamplifier which senses the charge on the timing plugs and atthe proper time gates the tripping SCR. This board also carriesthe diodes and resistors which make up the various referencevoltages for the control. Other circuits on this board are usedto inter-tie the tripping circuits and the reclose and reset cir-cuits.

DlODE BOARD The diode board (Figure16)consists of a group of diodes whichare connected to circuits on the other printed circuit boards.These diodes connect to the timing plugs, the reset circuit, thetrip circuit, and the reclose circuit. The board also contains thecircuit related to the closing circuit fuse.

RECLOSE-RESET BOARD The reclose-reset board ( Figure 17) carries all circuits neces-sary for reclosing and resetting. The various large capacitorson this board are the C parts of an R-C circuit operating alongwith unijunctions and SCR’s. The large SCR on this board isthe reclose SCR.

Closing Coil Control FuseOn solenoid-operated reclosers, the fuse will open the closing cir-cuit to protect the potential closing coil in the recloser if closingcannot be accomplished due to low closing voltage. On motor-operated reclosers, the fuse is connected in series with the clos-ing circuit contactor in the recloser.

A Buss Type MDQ-3/8 amp, 250-volt fuse, manufactured byBussman Manufacturing is used and a box of five spare fuses issupplied with each control. Fuses of similar ratings by other man-ufacturers have slightly different characteristics and should not beused for replacement.

CAUTION: Use only Buss Type MDQ-3/8 ampfuses. Previously, all Form 3A and most earlier con-

trols were supplied with Buss Type MDL-3/8 amp fuses.Buss has redesigned and changed the characteristics ofthat fuse and it is no longer suitable for use on any Form3 or Form 3A control. Failure to use proper closing coilcontrol fuse will result in unnecessary fuse operation andprevent the recloser from closing.

!

NOTE: Buss has redesigned the MDL-2.5 amp fuse that is used on con-trols shipped with reciosers having “quick-close” mechanisms such asType VSO and VSMT reclosers. The characteristics of the new single ele-ment MDL-2.5 fuse do not affect the application in the control. Buss willalso continue to manufacture the original dual element version of the fuseunder the new designation of MDQ-2.5. The MDQ-2.5 amp fuse will besupplied with controls for this application. Both the MDL-2.S amp fuseand the MDQ-2.S amp fuse are acceptable for this application.

INTERCHANGEABILITY OF BOARDSBETWEEN FORM 2, FORM 3 AND FORM 3AELECTRONIC CONTROLS.The battery-charger, phase-trip #1, phase-trip #2, ground-trip#1 and ground-trip #2 circuit boards can electrically be inter-changed between Form 2, Form 3 and Form 3A controls.However, the Form 2 circuit boards have an offset connectorwhich can result in clearance problems when Form 2 and Form3/3A boards are mixed in the same control. This procedure istherefore not recommended except in an emergency.

The fixed rate battery charging board (MEA 388-1 ) is electri-cally interchangeable between Form 2, Form 3 and Form 3Acontrols, when replacing another fixed rate board. The temper-ature regulated charging board (MEA 1172) should only beused to replace another charging board of the same type.

The upper three circuit boards (output, diode, and reclose-reset boards) are not interchangeable between Form 2 andForm 3/3A controls. Interchanging them will cause controlmisoperation, and may cause circuit board damage.

TROUBLESHOOTING AND TESTINGA number of relatively simple circuit tests can be made onthe ME electronic control. These tests will indicate whethermajor circuits are operating properly or not, but they will notnecessarily isolate the faulty component within the circuit.For easy reference to testing points, refer to Figures 18 and19 for Form 3 controls and Figures 20 and 21 for Form 3Acontrols. When appropriate, isolated test points will beshown for individual circuit tests with reference to the prop-ertie board (Figures 18 to 21).

Pre-Check When troubleshooting a control reported to have failed or tohave not worked properly, always check for simple problemsfirst.

Detailed Circuit Checks The following test procedures require only the following twotest devices.

A volt-ohm meter will be required (minimum meter inputimpedance 20,000 ohms per volt) to perform tests. The Kyle Type MET test set, or an actual recloser with a

source of primary or secondary test currents can also be used toperform tests.

If a circuit board failure is suspected, always check orchange the diode board first because:• The diode board circuits operate in conjunction with the tim-

ing plugs, the output circuit, reset circuit, and reclosing cir-cuit.

• A primary diode failure on the diode board can cause sec-ondary failures on the output board or reclose set board.

NOTE Diode board short circuits are very rare in controls manufacturedafter 1970.

If this does not isolate the problem, continue with the circuittest.

NOTE: The above voltages are proportional to the recloser line currentand can be used to calculate the actual load current on the differentphases, using a digital AC voltmeter such as a Fluke 77 series. The fol-lowing formula can be used.

(Volts on (ResistorLine Amps = resistor x value amp)

0.17Example: 0.023-volts (23-millivolts) measured across a 560-amp phaseresistor is equivalent to 75.7-amps recloser-load current.Total accuracyis approximately +5%.

2. Measure voltage across matching transformer secondaries(Figures 23 and 24) with 100% of minimum-trip current ap-plied to control. The test terminals on “T1 “ are shown inTable2. The voltages should be:• Phase Transformers—6.5-Vac• Ground Transformers—1.2-Vac

Failure to get these voltage readings can be a result of:A. Opens in current source, control cable, matching trans-

former windings, or wiring to the transformers and asso-ciated components.

B. Shorts in the control’s male input-cable receptacle.

NOTE: Matching transformers are interchangeable between Form2, 3, and 3A controls.

Failures to get these signals are most likely due to troubles onthe phase-trip No. 2 or ground-trip No. 2 circuit boards or possi-bly with the phase-trip No.1 or ground-trip No.1 boards. Batteryvoltage below 21-Vdc will cause control misoperation of the min-imum-trip, timing and trip signals of the control. Battery voltageabove 23 volts will operate the circuits correctly.

TIME CURRENT CHARACTERISTIC CURVES (TCC)NOTE: Since some volt meter burdens will change control calibration, thistest will only verify TCC plug operation.

To check the charging of the phase-or-ground-TCC plug, measurethe voltage drop at the tie board and the TCC socket pin testpoints listed in Table 5. Make connections and raise currentto120% minimum-trip level.

Failure to get a sudden voltage change for a fast TCC plug or agradual change for a slow TCC plug can be caused by trouble onthe phase-trip No. 2 or ground-trip No. 2 board, trouble on the var-ious timing plugs, open diodes on the diode board, or open con-tacts on the phase- or ground-trip socket No. 1 selector switches.*

* Problems on selector switches are rare on ME controls above S/N 6000.

TABLE 5Tie Board/TCC Socket Pin Test Points for TCC Charging(120% Minimum-Trip) (Figures 31,32 and 33)

* On a fast TCC curve the voltage will drop from 24-Vdc to less than 7-Vdc theinstant the fault current increases above minimum-trip.

* * On a delayed TCC plug an obvious time delay can be observed as the meter volt-age slowly drops from 24-Vdc to 7-Vdc at which time the unit trips

Figure 48.Comparison of charging rates.

BATTERY CHARGINGTo check the battery charging operation:1. Make sure control is in home (reset) position by moving

manual operator to “CLOSE.”2. Connect a dc milliammeter into right hand pair of battery-test

terminals(←l→ ),see Figure 47. Loosen both terminalsslightly and disconnect shorting link from between terminals.

3. With battery charger deenergized, current will flow oppositeto the direction shown by CHG. Under normal conditions,quiescent drain will be 1-1/2-to 2-mA. However, shorter timereset plugs and certain accessories can, as shown in Table11, increase quiescent drain above nominal value.

NOTE: To verify the charge/discharge polarity of the test meter,momentarily actuate the LAMP/LOCKOUT TEST toggle switch to"LAMP TEST." The current measured is a discharge current.

closed) 6Targets 1.9

* For complete list of accessory quiescent drain, see the Service Informationmanual on the MET Tester, S28O-76-1.

4. With the battery charger energized, current will flow in thedirection shown by CHG. The charging rate should beapproximately 17-mA minus the discharge rate measured inStep 3, if the control is equipped with the fixed rate batterycharging board ( MEA 388-1). The charging rate wilI varywith internal control cabinet temperature if equipped with the

temperature regulated charging board (MEA 1172), See Figure48). A typical charging rate will be about 27 mA, at normal roomtemperature.

NOTE: The 17-mA charging rate is a nominal value based on a 27-voltbattery and rated input parameters (e.g. 120-Vac). Even under thesestandard conditions. a variation of +2-mA may be observed in thecharging rate.

Prior to 1978 many recloser-control combinations (controlserial numbers below 26000) had the battery-charging circuitryin the recloser. Refer to ME control installation manual S280-75-1 for exact Control-Recloser interchangeability.• In the RE & WE family (Form 3 ME Control era), where the

charging supply is taken from the line on B phase, at least40-amps must flow in B phase for a minimum of 12 hours per24-hour day to maintain an adequate battery charge.

• In the motor operated equipment (VS, ME and CE family)manufactured between 1969 and 1978 the charging supply istaken from the 240-Vac motor supply that is required to oper-ate the recloser. To maintain battery charge on these units,the 240-Vac supply must be connected to the recloser, andthe recloser and control must be connected via the controlcable. After 1978 (above serial number 26000) most controlswere provided with battery-charging circuitry within the con-trol itself. These require 120-Vac (or 240-Vac) to be connect-ed to the control’s power-supply-input terminals.Failure to get the proper charging rate can be caused by

either a high control quiescent-battery discharge rate or by amalfunction in the battery-charger circuitry. To help isolate prob-lems in the battery-charging circuitry, see Figures 49, 50 and 51and Table 12.

NOTE: A totally discharged battery may indicate an excessive quies-cent-battery discharge rate due to a problem in the ME control. Testquiescent-battery discharge rate with a fully charged battery.

MECHANICAL AND ELECTRICAL HARDWAREAll mechanical and electrical hardware components (selectorswitches, toggle switches, manual switch, operations counter,trip sockets, phase sockets, resistor brackets, fuse receptacle,etc.) can be visually or electrically checked. If replacement isneeded, remove wires, noting their exact placement, remove allconnecting hardware and then remove the existing component.Install the new component by reversing procedure. SeeAppendix V for connection diagrams for ME controls Form 2, 3,and 3A.

BATTERY MAINTENANCEBattery Specifications• Nickel-cadmium. • 24-volts (20 cells in series). • 1.0 Ampere hour capacity (10 hour rate).• Charging rate: 50-mA maximum.• Weight: 41.5 oz. • Length: 10”. • Width: 2”. • Height: 2”.

Maintaining Battery ChargeThe battery is fully charged and ready to use just prior to ship-ment. For storage at temperatures under 70-degrees, the bat-tery will maintain adequate charge for operation up to 1-monthwithout trickle charging. However, extremely high ambient stor-age temperatures can result in a battery shelf-life of as little asone month. Thus we recommend that a control battery in stor-age not be left off charge for a period of more than 1-month.

Two convenient methods exist for applying a trickle chargeto the control battery.1. Connect the battery to the ME control and energize the

potential charger.

CAUTION: Shorting battery positive to batterynegative at the battery test terminals will cause

permanent damage to the control. The control will beinoperative and possible misoperation (unintentionaloperation) of the recloser may result.

!

CAUTION: Shorting the battery positive toground will damage a resistor on the control input

board, this will result in the battery negative floating,with respect to ground.

!

CAUTION: Do not short battery positive to thecontrol cabinet (or other ground). If shorted on a

Form 3 control the control will be permanently damaged,the control will be left inoperative and possible misoper-ation (unintentional operation) of the recloser mayresult. If shorted on a Form 3A control a resistor on theinput board will be destroyed; however, the control willremain operative.

!

WARNING: High voltage. The COMMON ACGND terminal is connected to the control cabinet.

If the incoming 120-Vac supply is inadvertently connect-ed to the common terminal the control cabinet will be at120-Vac potential. Contact with high voltage will causesevere personal injury or death.

!

2. A KA1142ME3 120-Vac battery charger is available for main-taining one ME control battery.

The KA1142ME3 battery charger provides two chargingrates, 15-mA and 50-mA. The 15-mA charging rate is used tomaintain a battery at full charge. The 50-mA rate is used tocharge a discharged battery. A battery must be charged atthe 50-mA rate for 48 hours.

NOTE: A fully discharged battery can be brought to full charge inabout 7-days with the control’s potential charger, if the battery isgood. The KA1142ME3 battery charger, at the 50-mA charge level,will recharge battery in about 48 hours.

Field Testing a BatteryNOTE: The battery in the Form 3 and 3A control has a steady drain ofapproximately 1.5- to 2.5-milliamperes (may be as high as 4.5-mil-liamperes with certain accessories).

To check the condition of a battery, a field test can easily bemade. To positively insure proper control operation, this test isconservative; failure to pass does not necessarily mean the bat-tery needs replacement. But a more thorough test can then beperformed—normally in a repair or maintenance shop.

To field test:

1. From the battery test terminals on the control front panelmeasure the battery voltage (see Figure 52). If battery volt-age is below 24-volts, the battery is either low on charge oris faulty. The battery should be removed for recharging andretested before returning to service.

2. If battery voltage is above 24-volts, a power delivery checkshould be made. To load the battery, a 10-ohm resistor (mini-mum of 10-watt size) is required. To test the battery—whilemeasuring battery voltage connect a 10-ohm resistor acrossthe battery test terminals, for approximately 2-3 seconds.The battery voltage should drop by no more than 3-voltsfrom the open circuit voltage, for ambient temperaturesabove 20 degrees F.

NOTE: Either a KA638ME voltmeter accessory or a KMET test setcan be used for the load test. Both devices have an internal 10-ohmload resistor.

3. If the temperature is below 20-degrees F. the voltage shouldbe approximately that shown by the lower curve in Figure53. If the voltage is lower than this, the battery should beremoved for shop testing.

Figure 53.Typical voltage versus temperature characteristics of nickel-cadmium battery.


36

Shop Testing a BatteryBefore testing, the top and bottom covers of the battery shouldbe removed. Then the following tests can be made.1. Check for leaking cells. These are detectable by the pres-

ence of a white powdery deposit of electrolyte.2. Measure voltage across each cell. Any cell measuring 0.0

volts is cause for immediate rejection of the entire battery.3. If all cells have at least 0.1-volts or more, charge the battery

using the KA1142ME battery charger. All cells should haveet least 1.0-Vdc within 5 minutes. Any battery failing thistest should be rejected.

4. Charge the battery for 48 hours with the KA1142ME batterycharger.

5. Place a 10-ohm load (a KA638ME voltmeter or MET Tester

has this built in) across the battery for approximately 2-3 sec-onds. The voltage must not drop more than 3-volts below theopen circuit voltage for temperatures above 20-degrees F.

6. Make a capacity check. Discharge the battery through a 100-ohm, 12-watt resistor for 3-hours. At the end of this period andwhile under load, check the individual cell voltages. No cellshould read less than 1.1-volts.

7. Remove the 100-ohm resistor. Recheck the open-circuit volt-age on each cell after 7-days. All cells should measure veryclose to the same voltage level. Do not recharge the batteryprior to this test.

If the battery passes the above test, it is in satisfactory condi-tion; replace the battery covers, recharge (48-hours using theKA1142ME battery charger) and return to service.
