S280-75-2 INTRODUCTION Service Information S28O-75-2 covers basic maintenance instructions for the Type ME electronic control. The manual includes a general description of the control, its operating principles and instructions for periodic inspection and testing. Service parts lists along with ordering information are included in Appendix IV. An introduction to the Form 3A, Type ME, electronic control is available on video cassette (KSPV3); in this program the function of all standard operating and programming features is explained. The factory service department offers maintenance training courses for Type ME controls. These classes, taught by ex- Figure 2.

DESCRIPTION The Kyle Type ME electronic recloser control (Figure 1 ) is comprised of a number of programmable, solid-state electronic circuits that perform the command functions involved in automatic recloser operation. It is used to operate all Kyle electronically controlled reclosers. A swing-out front panel contains the programming and operating elements of the control (Figure 2). The upper, black portion 88937KMA 3 Type ME Electronic Recloser Control of the front panel contains the plug-in components and setting knobs for programming automatic recloser operation. The switches and indicators used for manual operation and service are grouped on the bottom, light portion of the panel. The front panel is backed by a printed-circuit tie board which supports and interfaces the plug-in circuit boards with other related circuit components (Figure 3). Program-altering, remote control, indicating, and general convenience accessories can be added to further expand and enhance the application capabilities of the control. Line current flowing through the recloser is sensed by three internally mounted bushing-current transformers, one on each phase. When the phase current, or the zero-sequence (ground) current, exceeds its programmed minimum-trip value, the electronic control initiates the programmed sequence of recloser tripping and reclosing operations. If the fault is temporary, the control ceases to command recloser operations after successful reclose, and the control resets to the start of its operating sequence after a preset time delay. If the fault is permanent, the control performs its complete programmed sequence of recloser commands and locks out with the recloser open. Once locked out, the control must be manually reset to the start of its operating sequence which simultaneously closes the recloser. Factory-calibrated timing plugs establish the time-current characteristics for both phase and ground tripping. Two sets of individual timing curves provide dual timing for both phase and ground. Figure 3. Tie board on back of front panel mounts the individual printed circuit boards. 4 88938KMA S280-75-2 OPERATION Since the understanding of the terminology and the operating sequences of an electronically controlled recloser is important to the rest of this maintenance manual, examples of typical operating sequences of an electronically controlled recloser under permanent fault (Figure 4) and temporary fault (Figure 5) conditions are given. The definition of the terms 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 current to help prevent nuisance tripping on inrush currents, while still being sensitive to low level faults. • Over-Current—Any current that exceeds the minimumtrip level of the control. • Permanent Fault—Any over-current condition that persists through the operating sequence of the control. • Temporary Fault—Any over-current condition that does not persist through the operating sequence of the control. • Home Position—Position of sequence relay immediately after a • • • • • reset operation of the control. Reset operation can be either manual, 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 operation within the operating sequence of the control. Fault Level Current—Any current that exceeds the minimumtrip level of the control. Normal Load—Any current below the minimum-trip level of the control. Figure 4. Typical operating sequence of an electronically controlled recloser under permanent fault conditions. Figure 5. Typical operating sequence of an electronically controlled recloser under temporary fault conditions. 5 Type ME Electronic Recloser Control A functional block diagram of the control operation is shown in Figure 6. Line current conditions are continuously monitored by the three bushing-type current transformers in the recloser. output from these transformers is fed to the trip network in the control, which includes: the minimum-trip resistors, isolation transformers, and rectifier circuits. If current remains above the minimum-trip level, the tripping —reclosing sequence of fast and delayed operations is repeated as programmed to lockout. When current above the selected minimum-trip level is detected in one or more phases, the following chain of events will occur for an operating sequence of two-fast and twodelayed operations: The overcurrent signal is integrated with time on the characteristic curve of the timing plug in Socket 1 to produce the signal which energizes the trip circuit. Energizing the trip circuit connects the battery to the trip solenoid, tripping the recloser. Simultaneously, the sequence relay advances to energize the first reclosing interval-delay plug. Upon expiration of this reclosing interval delay, a closing signal, from the control, closes the recloser, and the sequence relay sets up the circuitry for the second fast trip operation. If the overcurrent is cleared before the operating sequence reaches lockout, the reset-delay circuit starts timing when the recloser closes into the unfaulted line. When the reset-delay plug 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 the fault restart before the reset plug times out, the control will continue its operating sequence, where it left off last, and the reset-delay timing will be erased. Ground-fault sensing and tripping operations occur exactly the same as phase-fault sensing and tripping, except that zero-sequence (ground) current is sensed instead of phase current. The ground-fault circuitry includes its own minimumtrip resistor, fast and delayed trip-timing plugs, and number of fast operations setting. Reclose and reset intervals and operations to lockout are common for both phase-trip and groundtrip modes of operation. Figure 6. Functional block diagram of Type ME control. 6 PERlODIC FIELD INSPECTlON AND MAINTENANCE Periodic inspection of the ME control should include these procedures: CAUTION: In order to prevent possible, misoperation (unintentional operation) of the recloser, the control must be removed from service prior to performing any maintenance, testing or programming changes. ! 1. Remove control from service (if connected to an in service recloser): A. Switch Ground Trip Block switch to “BLOCK”. B. Disconnect control cable from control. WARNING: High voltage. Contact with high voltage will cause serious personal injury or death. Follow all locally approved safety procedures when working around high voltage lines and equipment. ! 2. Check the outer surface of the control cabinet for paint scratches. Touch up any paint scratches to maintain the cabinet condition. 3. If the second entrance hole in the bottom of the cabinet is not used, be sure that the hole plug is secure in the bottom of the housing to maintain its weatherproof design. 4. Inspect the gasketing. Check the control interior for any moisture or foreign matter. Repair or correct if necessary. 5. Check that the timing plugs, reset and reclosing interval delays, and minimum-trip resistors are firmly in their sockets (Figure 2). 6. Swing open the front panel. Check to see that all leads to tieboard terminals are secure (Figure 7). CAUTION: Shorting battery positive to battery negative at the battery test terminals will cause permanent damage to the control. The control will be inoperative and possible misoperation (unintentional operation) of the recloser may result. ! S280-75-2 88939KMA Figure 7. View of a Form 3A tie board (back if front panel. Notations in parenthesis after callout refer to the circuit points on the tie board diagram illustrated in Figure 57. 7. Check battery voltage. Three battery test terminals in the lower right corner of the panel (Figure 2) are used to check battery voltage, quiescent drain, and charging rate. Refer to the “Battery Maintenance” instructions in this manual. The left-hand pair of terminals (V) are connected directly across the battery output to check battery voltage. The red terminal (far left) is positive (+). The output voltage of a fully charged 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 if connections are in order. Close front panel and secure firmly with fasteners. 7 Type ME Electronic Recloser Control Figure 8. Detailed block diagram of Type ME control in lockout position. Letters in circles (A,B, etc.) refer to control cable receptacle connection pins and to test points referred to in the "Troubleshooting and Testing" section. 9. Check control battery charging rate before returning the control/recloser to service; see the “Battery Maintenance” section for details on charging rate testing. NOTE: The servicing procedures outlined in this manual are for a standard Type ME Form 3 and Form 3A control and do not include the operational checks of any of the accessories that may be attached. In some cases the accessories may modify the standard operating characteristics of the Type ME control. Refer to catalog bulletin 280-75 for accessories furnished and/or Accessory operation, Testing, and Installation manuals listed in Appendix lll of this manual. 10. Return control to service: A. Check battery to ensure that it is properly connected. B. Move Manual Control Switch to match position of recloser (open or closed). C. Reconnect control cable to control. D. Switch Ground Trip Block switch to “NORMAL”. 8 SERVICING Circuit Logic Line current conditions are monitored continuously by three bushing-current transformers in the recloser, one on each phase. The current transformers are connected to the controlphase matching transformers in a typical “WYE” to “WYE” configuration. Zero-sequence current is derived from the vector sum of the phase currents and fed to a fourth ground matching transformer. The minimum-trip resistors calibrate the overall recloser trip current by diverting a portion of the recloser current from the control matching transformers. The four matching transformers isolate the various signals from each other and deliver an ac voltage proportional to the recloser-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 of the terminals are missing or in a slightly different location. From this point, phase- and ground-trip signals are very similar, and only phase signals will be described. The phase-trip No. 1 board circuitry, consisting of a threephase full-wave rectifier, which converts the ac input signal from three phase to a single do signal. The do signal is applied to the phase-trip No. 2 board which measures the do level, and determines whether a fault current exists at the recloser. If the load current conditions are in the fault region, the minimum-trip portion of the phase-trip No. 2 board switches on, allowing the time-current curve circuits to start their programmed time delay. The time-current curves are driven by the same do voltage output of the phase-trip No. 1 board, and as a result higher faultcurrent levels will result in a shorter time delay before tripping. 9 Type ME Electronic Recloser Control After the timing plugs have completed their cycle, the output board is triggered. The output board applies a 24-Vdc signal to the recloser trip coil, the control counter, and the control sequence relay. The output board is switched off when the recloser “a” contact de-energize the circuitry, including the sequence relay. The sequence-relay rotary contacts then advance to the next position in the tripping and reclosing cycle. The recloser “b” contacts then close, connecting battery power to the reclose intervals of the control which provides a time delay for reclosing the recloser. The rotary close solenoid is then energized through the recloser “b” contacts, the control fuse, and the reclose portion of the control circuitry. This mechanically closes the closing contactor in the recloser— allowing the closing solenoid to be energized. After closing the recloser “b” contact opens, this removes do power from the entire closing circuit. The automatic reset portion of the Form 3A control is energized by the sequence relay and the recloser “a” contact; if a fault does not exist on either phase or ground trip, reset timing is initiated (unless connected to time after first trip). If a fault exists on either phase or ground, the reset timing is erased and is blocked for the duration of the fault. For Form 3, reset timing begins after the first tripping operation. Should the reset time-delay operate before the recloser has locked open, the sequence relay will return to the starting position and a new sequence 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 through a current limiting resistor and isolating transformer to the battery charging board. The battery charging board converts the input to dc and supplies charging current to the control battery. on Form 3 controls, the battery is charged by bushing current transformers on the recloser unless equipped with an ac charging accessory. on motor operated reclosers, the ac supply to the motor also supplies power to the Form 3 battery charger. Figure 10. Battery-charging board, 10 82027aKMA Plug-in Circuit Boards - Function The ME control contains a total of eight plug-in circuit boards on which are assembled the bulk of its operating circuits. The boards and their function will be discussed individually in the order they appear on the tie board, starting with the bottom board. BATTERY-CHARGING BOARD The lowest board in the rack is the battery-charging board (Figure 10). Prior to serial number 50070 controls were equipped with a fixed rate potential charging board (MEA 388-1 ) as standard equipment. After serial number 50070 a temperature regulated battery-charging board (MEA 1172) has been supplied as standard. ! The fixed rate charging board consists of a full-wave bridge rectifier, a capacitor, a reference zener diode and some resistors. The resistors control the charging rate into the battery, from the zener supply voltage. The temperature regulated battery-charging board also makes use of a full-wave bridge rectifier, a capacitor, and a zener diode (used to regulate voltage). In addition a temperature sensitive thermistor is added to regulate the bias over a pair of transistors. These transistors are used in the circuit output to regulate the charging rate, in response to temperature. Several resistors are used in the transistor bias circuit; and one resistor is used to limit the maximum charging rate. A diode is placed in the output to protect the circuit from reverse bias. ‘ Energy for either battery-charging board comes from the 120or 240-Vac source,through current limiting resistance and a potential transformer. CAUTION: Do not replace a MEA 388-1 board with a MEA 1172, or vice-versa. A MEA 388-1 board will be damaged if replaced ffor a MEA 1172. A MEA 1172 will not provide adequate charging current if replaced for a MEA 388-1 ! 88940KMA S280-75-2 PHASE-TRIP NO. 2 BOARD The phase-trip No. 2 board (Figure 12) carries the remaining circuits for minimum-trip and the wave-shaping circuits for the timing plugs. There are two tabs on the phase-trip No. 2 board for the Form 3 and 3A control. one tab is labeled minimum-trip (MIN. TRIP)* and is battery plus for normal line currents and switches to battery 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. Figure 20. Capacitor for CT-type battery charger. 86773KMA GROUND-TRIP NO. 1 AND NO. 2 BOARDS The next two boards up, ground-trip No. 1 and No. 2 (Figures 13 and 14), are like the corresponding phase-trip boards, except that the ground-trip No. 1 board has only a single input diode bridge for ground current. These boards carry almost the same parts and same configurations as the corresponding phase boards. PHASE-TRIP NO. 1 BOARD The second board from the bottom is the phase-trip No. 1 board (Figure 11). It has three full-wave diode sets, one for each phase, along with a loading resistor for each phase. This board also has the beginning circuits for the minimum trip function. Figure 13. Ground-trip No. 1 board. Figure 11. Phase-trip No. 1 board. 88941KMA Figure 14. Ground-trip No. 2 board. 88943KMA 88944KMA 11 Type ME Electronic Recloser Control OUTPUT BOARD The output board (Figure 15) of the control has another do amplifier which senses the charge on the timing plugs and at the proper time gates the tripping SCR. This board also carries the diodes and resistors which make up the various reference voltages for the control. Other circuits on this board are used to inter-tie the tripping circuits and the reclose and reset circuits. Figure 17. Reclose-reset board. 88947KMA Closing Coil Control Fuse Figure 15. Output Board. 88945KMA DlODE BOARD The diode board (Figure16)consists of a group of diodes which are connected to circuits on the other printed circuit boards. These diodes connect to the timing plugs, the reset circuit, the trip circuit, and the reclose circuit. The board also contains the circuit related to the closing circuit fuse. On solenoid-operated reclosers, the fuse will open the closing circuit to protect the potential closing coil in the recloser if closing cannot be accomplished due to low closing voltage. On motoroperated reclosers, the fuse is connected in series with the closing circuit contactor in the recloser. A Buss Type MDQ-3/8 amp, 250-volt fuse, manufactured by Bussman Manufacturing is used and a box of five spare fuses is supplied with each control. Fuses of similar ratings by other manufacturers have slightly different characteristics and should not be used for replacement. CAUTION: Use only Buss Type MDQ-3/8 amp fuses. Previously, all Form 3A and most earlier controls were supplied with Buss Type MDL-3/8 amp fuses. Buss has redesigned and changed the characteristics of that fuse and it is no longer suitable for use on any Form 3 or Form 3A control. Failure to use proper closing coil control fuse will result in unnecessary fuse operation and prevent the recloser from closing. ! NOTE: Buss has redesigned the MDL-2.5 amp fuse that is used on controls shipped with reciosers having “quick-close” mechanisms such as Type VSO and VSMT reclosers. The characteristics of the new single element MDL-2.5 fuse do not affect the application in the control. Buss will also continue to manufacture the original dual element version of the fuse under the new designation of MDQ-2.5. The MDQ-2.5 amp fuse will be supplied with controls for this application. Both the MDL-2.S amp fuse and the MDQ-2.S amp fuse are acceptable for this application. INTERCHANGEABILITY OF BOARDS BETWEEN FORM 2, FORM 3 AND FORM 3A ELECTRONIC CONTROLS. Figure 16. Diode Board. 88946KMA RECLOSE-RESET BOARD The reclose-reset board ( Figure 17) carries all circuits necessary for reclosing and resetting. The various large capacitors on this board are the C parts of an R-C circuit operating along with unijunctions and SCR’s. The large SCR on this board is the reclose SCR. 12 The battery-charger, phase-trip #1, phase-trip #2, ground-trip #1 and ground-trip #2 circuit boards can electrically be interchanged between Form 2, Form 3 and Form 3A controls. However, the Form 2 circuit boards have an offset connector which can result in clearance problems when Form 2 and Form 3/3A boards are mixed in the same control. This procedure is therefore not recommended except in an emergency. The fixed rate battery charging board (MEA 388-1 ) is electrically interchangeable between Form 2, Form 3 and Form 3A controls, when replacing another fixed rate board. The temperature regulated charging board (MEA 1172) should only be used to replace another charging board of the same type. The upper three circuit boards (output, diode, and reclosereset boards) are not interchangeable between Form 2 and Form 3/3A controls. Interchanging them will cause control misoperation, and may cause circuit board damage. S280-75-2 TROUBLESHOOTING AND TESTING A number of relatively simple circuit tests can be made on the ME electronic control. These tests will indicate whether major circuits are operating properly or not, but they will not necessarily isolate the faulty component within the circuit. For easy reference to testing points, refer to Figures 18 and 19 for Form 3 controls and Figures 20 and 21 for Form 3A controls. When appropriate, isolated test points will be shown for individual circuit tests with reference to the propertie board (Figures 18 to 21). TABLE 1 Pre-Check Trouble Check 1. Completely inoperative Are boards plugged in correctly? Is battery connected and fully charged (23-Vdc minimum)? Is control cable connected? Is control programming correct? 2. Won’t close Is the control fuse good? RE and WE series reclosers—Is the yellow operating handle up? CE, ME and VS series reclosers—Is the manualtrip/reset knob in the proper position? RE and WE series reclosers—Can the rotary close solenoid be heard to operate? If so, test for high voltage to recloser closing coil (refer to specific recloser maintenance manual— Appendix II). Is there 120- or 240-Vac power to the control? 3. Won’t trip Is battery connected and fully charged (23-Vdc minimum)? Is control cable properly connected? 82040KMA Figure 18. Form 3 electronic control tie board.The test points listed above will be covered in detail in the "Detailed Circuit Check" section of this manual. 13 Type ME Electronic Recloser Control 82047KMA Figure 19. Form 3 electronic control tie board and control back panel.The test points listed above will be covered in detail in the "Detailed Circuit Check" section of this manual. Pre-Check When troubleshooting a control reported to have failed or to have not worked properly, always check for simple problems first. Detailed Circuit Checks The following test procedures require only the following two test devices. A volt-ohm meter will be required (minimum meter input impedance 20,000 ohms per volt) to perform tests. 14 CAUTION: Be sure that test equipment leads have insulated clips to prevent short circuiting adjacent ME control terminals during testing. Shorting terminals may cause permanent damage to circuit components. The control may be inoperative and possible misoperation (unintentional operation) of the recloser may result. ! The Kyle Type MET test set, or an actual recloser with a source of primary or secondary test currents can also be used to perform tests. S280-75-2 88948KMA Figure 20. Form 3A electronic control tie board.The test points listed above will be covered in detail in the "Detailed Circuit Check" section of this manual. If a circuit board failure is suspected, always check or change the diode board first because: • The diode board circuits operate in conjunction with the timing plugs, the output circuit, reset circuit, and reclosing circuit. • A primary diode failure on the diode board can cause secondary failures on the output board or reclose set board. NOTE Diode board short circuits are very rare in controls manufactured after 1970. If this does not isolate the problem, continue with the circuit test. 15 Type ME Electronic Recloser Control 88939KMA Figure 21. Form 3A electronic control back panel.The test points listed above will be covered in detail in the "Detailed Circuit Check" section of this manual. 16 S280-75-2 INPUT CIRCUITS WARNING: High voltage. Contact with high voltage will cause serious personal injury or death. Follow all locally approved safety procedures when working around high voltage lines and equipment. ! To check input signals to the control, measure the voltage across the minimum-trip resistors and matching transformer secondaries as follows: 1. Measure voltage across minimum-trip resistors (Figure 22) with 100% of minimum-trip current applied to control. The voltage should be approximately: • Phase Resistors—0.17-Vac (170 millivolts) • Ground Resistors—0.26-Vac (260 millivolts) Figure 23. Block diagram of matching transformers (Table 2). See Figure 8 for complete block diagram. 2. Measure voltage across matching transformer secondaries (Figures 23 and 24) with 100% of minimum-trip current applied to control. The test terminals on “T1 “ are shown in Table 2. 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 transformer windings, or wiring to the transformers and associated components. B. Shorts in the control’s male input-cable receptacle. CAUTION: When measuring voltage between the violet and gray leads be careful not to short between the gray wire and the B+ terminal. If the gray wire is shorted to the B+ terminal the Phase Trip #1 board will be permanently damaged. ! Figure 22. Measured voltage across minimum-trip resistors. 82040KMA NOTE: Matching transformers are interchangeable between Form 2, 3, and 3A controls. NOTE: The above voltages are proportional to the recloser line current and can be used to calculate the actual load current on the different phases, using a digital AC voltmeter such as a Fluke 77 series. The following formula can be used. (Volts on (Resistor Line Amps = resistor x value amp) 0.17 Example: 0.023-volts (23-millivolts) measured across a 560-amp phase resistor is equivalent to 75.7-amps recloser-load current.Total accuracy is approximately +5%.

Failure to get a sudden voltage change for a fast TCC plug or a gradual change for a slow TCC plug can be caused by trouble on the phase-trip No. 2 or ground-trip No. 2 board, trouble on the various timing plugs, open diodes on the diode board, or open contacts on the phase- or ground-trip socket No. 1 selector switches.* * Problems on selector switches are rare on ME controls above S/N 6000.

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 terminals slightly and disconnect shorting link from between terminals. 3. With battery charger deenergized, current will flow opposite to the direction shown by CHG. Under normal conditions, quiescent drain will be 1-1/2-to 2-mA. However, shorter time reset plugs and certain accessories can, as shown in Table 11, increase quiescent drain above nominal value. temperature regulated charging board (MEA 1172), See Figure 48). A typical charging rate will be about 27 mA, at normal room temperature. NOTE: The 17-mA charging rate is a nominal value based on a 27-volt battery and rated input parameters (e.g. 120-Vac). Even under these standard conditions. a variation of +2-mA may be observed in the charging rate. 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.

With the battery charger energized, current will flow in the direction shown by CHG. The charging rate should be approximately 17-mA minus the discharge rate measured in Step 3, if the control is equipped with the fixed rate battery charging board ( MEA 388-1). The charging rate wilI vary with internal control cabinet temperature if equipped with the Prior to 1978 many recloser-control combinations (control serial numbers below 26000) had the battery-charging circuitry in the recloser. Refer to ME control installation manual S28075-1 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 least 40-amps must flow in B phase for a minimum of 12 hours per 24-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 is taken from the 240-Vac motor supply that is required to operate the recloser. To maintain battery charge on these units, the 240-Vac supply must be connected to the recloser, and the recloser and control must be connected via the control cable. After 1978 (above serial number 26000) most controls were provided with battery-charging circuitry within the control itself. These require 120-Vac (or 240-Vac) to be connected 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 a malfunction in the battery-charger circuitry. To help isolate problems in the battery-charging circuitry, see Figures 49, 50 and 51 and Table 12. NOTE: A totally discharged battery may indicate an excessive quiescent-battery discharge rate due to a problem in the ME control. Test quiescent-battery discharge rate with a fully charged battery. 31 Type ME Electronic Recloser Control Figure 49. Block diagram of test points for battery-charging circuitry.

If replacement is needed, remove wires, noting their exact placement, remove all connecting hardware and then remove the existing component. Install the new component by reversing procedure. See Appendix V for connection diagrams for ME controls Form 2, 3, and 3A. CAUTION: Do not short battery positive to the control 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 misoperation (unintentional operation) of the recloser may result. If shorted on a Form 3A control a resistor on the input board will be destroyed; however, the control will remain operative. ! BATTERY MAINTENANCE Battery 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 Charge The battery is fully charged and ready to use just prior to shipment. For storage at temperatures under 70-degrees, the battery will maintain adequate charge for operation up to 1-month without trickle charging. However, extremely high ambient storage temperatures can result in a battery shelf-life of as little as one month. Thus we recommend that a control battery in storage not be left off charge for a period of more than 1-month. Two convenient methods exist for applying a trickle charge to the control battery. 1. Connect the battery to the ME control and energize the potential charger. CAUTION: Shorting battery positive to battery negative at the battery test terminals will cause permanent damage to the control. The control will be inoperative and possible misoperation (unintentional operation) of the recloser may result. ! 1. From the battery test terminals on the control front panel measure the battery voltage (see Figure 52). If battery voltage is below 24-volts, the battery is either low on charge or is faulty. The battery should be removed for recharging and retested before returning to service. WARNING: High voltage. The COMMON AC GND terminal is connected to the control cabinet. If the incoming 120-Vac supply is inadvertently connected to the common terminal the control cabinet will be at 120-Vac potential. Contact with high voltage will cause severe personal injury or death. ! 2. A KA1142ME3 120-Vac battery charger is available for maintaining one ME control battery. The KA1142ME3 battery charger provides two charging rates, 15-mA and 50-mA. The 15-mA charging rate is used to maintain a battery at full charge. The 50-mA rate is used to charge a discharged battery. A battery must be charged at the 50-mA rate for 48 hours. Figure 52. Field testing a battery. NOTE: A fully discharged battery can be brought to full charge in about 7-days with the control’s potential charger, if the battery is good. The KA1142ME3 battery charger, at the 50-mA charge level, will recharge battery in about 48 hours. Field Testing a Battery NOTE: The battery in the Form 3 and 3A control has a steady drain of approximately 1.5- to 2.5-milliamperes (may be as high as 4.5-milliamperes with certain accessories). To check the condition of a battery, a field test can easily be made. To positively insure proper control operation, this test is conservative; failure to pass does not necessarily mean the battery needs replacement. But a more thorough test can then be performed—normally in a repair or maintenance shop. To field test: CAUTION: Shorting the battery positive to ground will damage a resistor on the control input board, this will result in the battery negative floating, with respect to ground. ! 2. If battery voltage is above 24-volts, a power delivery check should be made. To load the battery, a 10-ohm resistor (minimum of 10-watt size) is required. To test the battery—while measuring battery voltage connect a 10-ohm resistor across the battery test terminals, for approximately 2-3 seconds. The battery voltage should drop by no more than 3-volts from the open circuit voltage, for ambient temperatures above 20 degrees F. NOTE: Either a KA638ME voltmeter accessory or a KMET test set can be used for the load test. Both devices have an internal 10-ohm load resistor. 3. If the temperature is below 20-degrees F. the voltage should be approximately that shown by the lower curve in Figure 53. If the voltage is lower than this, the battery should be removed for shop testing. 35 Type ME Electronic Recloser Control Figure 53. Typical voltage versus temperature characteristics of nickel-cadmium battery. Shop Testing a Battery Before testing, the top and bottom covers of the battery should be removed. Then the following tests can be made. 1. Check for leaking cells. These are detectable by the presence 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 have et least 1.0-Vdc within 5 minutes. Any battery failing this test should be rejected. 4. Charge the battery for 48 hours with the KA1142ME battery charger. 5. Place a 10-ohm load (a KA638ME voltmeter or MET Tester 36 has this built in) across the battery for approximately 2-3 seconds. The voltage must not drop more than 3-volts below the open circuit voltage for temperatures above 20-degrees F. 6. Make a capacity check. Discharge the battery through a 100ohm, 12-watt resistor for 3-hours. At the end of this period and while under load, check the individual cell voltages. No cell should read less than 1.1-volts. 7. Remove the 100-ohm resistor. Recheck the open-circuit voltage on each cell after 7-days. All cells should measure very close to the same voltage level. Do not recharge the battery prior to this test. If the battery passes the above test, it is in satisfactory condition; replace the battery covers, recharge (48-hours using the KA1142ME battery charger) and return to service.
