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-
perienced service technicians, are held at the factory’s in-house
training facility. For additional information, contact your sales engineer.
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
Page 4

Figure 3.
Tie board on back of front panel mounts the individual printed cir cuit boar ds.
Type ME Electronic Recloser Control
88938KMA
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.

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 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 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 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.
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.
PERlODIC FIELD INSPECTlON
AND MAINTENANCE
Periodic inspection of the ME control should include these procedures:
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.
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.
CAUTION: In order to prevent possible, misoper-
ation (unintentional operation) of the recloser, the
control must be removed from service prior to performing
any 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 working around high voltage lines and equipment.

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.

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 3Acontrol 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 reclos-
er (open or closed).
C. Reconnect control cable to control.
D. Switch Ground Trip Block switch to “NORMAL”.
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.

Diagram of Form 3A tie board showing plug-in circuit boar d 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.

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.
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

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.
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.
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.

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.
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.
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.
Closing Coil Control 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.
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.

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).
Trouble Check
1. Completely Are boards plugged in correctly?
inoperative 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 oper-
ating handle up?
CE, ME and VS series reclosers—Is the manual-
trip/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)?

impedance 20,000 ohms per volt) to perform tests.
The Kyle Type METtest set, or an actual recloser with a
source of primary or secondary test currents can also be used to
perform tests.

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 tim-
ing plugs, the output circuit, reset circuit, and reclosing circuit.
•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 manufactured
after 1970.
If this does not isolate the problem, continue with the circuit
test.

WARNING: High voltage. Contact with high volt-
age will cause serious personal injury or death.
Follow all locally approved safety procedures when
working around high voltage lines and equipment.
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.

for complete block diagram.
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)
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%.
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 trans-
former windings, or wiring to the transformers and associated components.
B. Shorts in the control’s male input-cable receptacle.
NOTE: Matching transformers are interchangeable between Form
2, 3, and 3A controls.

To check the dc-load-current output signal, measure the voltage at tie board test points listed in Table 3 at 100% minimumtrip current.

Failures to get these signals are most likely due to troubles on
the phase-trip No. 2 or ground-trip No. 2 circuit boards or possibly with the phase-trip No.1 or ground-trip No.1 boards. Battery
voltage below 21-Vdc will cause control misoperation of the minimum-trip, timing and trip signals of the control. Battery voltage
above 23 volts will operate the circuits correctly. Refer to

TIME CURRENT CHARACTERISTIC CURVES (TCC)
NOTE: Since some volt meter burdens will change control calibration, this
test will only verify TCC plug operation.
To check the charging of the phase-or-ground-TCC plug, measure
the voltage drop at the tie board and the TCC socket pin test
points listed in Table 5. Make connections and raise current
to120% minimum-trip level.
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.

(120% Minimum-T rip) (Figures 31,32 and 33)
* On a fast TCC curve the voltage will drop from 24-Vdc to less than 7-Vdc the
instant 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

BATTERY CHARGING
To 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 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.
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.
TABLE 11
Quiescent-Battery Drain Above Normal*
Description Drain (mA)

10-second reset plug 0.8
Sequence coordination accessory (if blocked in
home) 0.8
Remote minimum-trip double-supervisory contacts
closed) 6
Targets 1.9
* For complete list of accessory quiescent drain, see the Service Information
manual on the MET Tester, S28O-76-1.
4. 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
temperature regulated charging board (MEA 1172), See Figure
48). Atypical 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.
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 oper-
ate 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 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 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.

trip sockets, phase sockets, resistor brackets, fuse receptacle,
etc.) can be visually or electrically checked. 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,

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.
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.
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.
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.
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:
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.
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.

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
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 condi-
tion; replace the battery covers, recharge (48-hours using the
KA1142ME battery charger) and return to service.
