low all locally approved procedures and safety practices

before installing or operating this equipment.

Additional Information

These instructions do not claim to cover all details or vari-

ations in the equipment, procedures, or process described

nor to provide directions for meeting every possible contin-

gency during installation, operation, or maintenance.

When additional information is desired to satisfy a problem

not covered sufficiently for the user's purpose, please con-

tact your Cooper Power Systems sales engineer.

Acceptance and Initial

Inspection

Each control (Figure 1) is completely assembled, tested,

and inspected at the factory. It is carefully calibrated,

adjusted, and in good condition when accepted by the

carrier for shipment.

Upon receipt, inspect the control thoroughly for damage

and loss of parts incurred during shipment. If damage or

loss is discovered, file a claim with the carrier immediately.

Handling and Storage

Take care during handling and storage to minimize the

possibility of damage. If the control is to be stored for any

length of time before installation, provide a clean, dry stor-

age area. If storage is in a humid atmosphere, make pro-

visions to keep the cabinet heater energized.

Note: To energize the cabinet heater, apply to 120 Vac to Ter-

minals 5 and 6 of the input terminal strip mounted verti-

cally on the back panel of the control cabinet. Refer to

Figure 4.

Control Battery Storage and

Charging

The nickel-cadmium control battery is fully charged prior

to shipment and is ready for use. The battery should only

be stored in a fully charged state. Permanent irreversible

damage will result if a battery is stored in a deeply dis-

charged state. The battery should be kept on a mainte-

nance charge of 15 mA until the control is put into service.

After three months of storage, check the open circuit volt-

age. The battery will require recharging if it is at or below

24 volts at 25˚C (77˚F). Never store batteries at tempera-

tures exceeding 47˚C (117˚F), as permanent damage can

result in one month. Storage at or below room tempera-

ture is recommended to prolong storage time and main-

tain capacity over time.

To maintain the battery charge, energize the control’s

built-in charger with AC power applied to the input termi-

nal block. If it is not possible to charge the battery with the

control’s built-in charger, a portable dual rate bench type

charger, catalog no. KA1142ME3, is available. The

charger provides a selectable output of either 15 mA for

maintaining a charged battery or 50 mA for charging a dis-

charged or partially discharged battery. Unless it the bat-

tery is known to be fully charged, it should be charged at

50 mA for 48 hours (CHARGE switch position) and then

maintained at 15 mA (MAINTAIN switch position) until the

battery is installed in the control and put into service.

Battery Connections

When the battery is shipped from the factory, the battery

source is disconnected and its output plug is taped to the

cabinet. Connect the battery plug into the mating connec-

tor to complete the battery circuit.

IMPORTANT: The battery must be disconnected prior

to shipping or storing the control.

IMPORTANT: Connect the control battery when AC

power is connected to the control’s AC supply Input

Terminal Block.

Form 3A Type ME Electronic Control Installation, Operation, and Testing Instructions

Description of Control

The Kyle Type ME Form 3A electronic recloser control is

comprised of a number of programmable, solid-state elec-

tronic circuits that perform the command functions

involved in automatic recloser operation.

Control Panel

A swing-out front panel contains the programming and

operating elements of the control (Figure 2). The upper,

black portion of the front panel contains the plug-in com-

ponents and setting knobs for programming automatic

recloser operation. The switches and indicators used for

manual operation and service are grouped on the bottom,

light portion of the panel.

Minimum-Trip

Resistors

Establish the minimum-

trip current levels for

ground and each

phase; cartridges are

marked in primary

amps and clamped in

place.

Ground-Trip

Operation Switch

Blocks all ground tripping in the

BLOCK position: Prevents uninten-

tional tripping during single-phase

switching operations.

Ground-Trip Selector

Programs the number of fast

ground-trip operations as

defined by the timing plug in

Socket 1; the remaining

(slower) operations to lock-

out are defined by the plug in

ground-trip Socket 2.

Phase-Trip

Selector

Programs the number of fast

phase-trip operations as

defined by the timing plug in

Socket 1; the remaining

(slower) operations to lock-

out are defined by the plug in

Phase-trip Socket 2.

Reclosing Interval

Plugs

Determines the delay inter-

val for each closing opera-

tion. The delay value is

determined by the position

of the plug in the socket

adapter. An instantaneous

plug is available for the first

reclose interval only.

Ground-Trip Timing

Plugs

Provide a variety of current-

integrated timing curves on

individual plugs for coordi-

nating the ground-trip opera-

tion with backup and

downline protective devices.

Phase-Trip Timing

Plugs

Provide a variety of current-

integrated timing curves on

individual plugs for coordi-

nating the phase-trip opera-

tion with backup and

downline protective devices.

Reset-Delay Plug

Determines the delay inter-

val before the control

resets after a successful

reclosure during an opera-

tion sequence. The delay

value is determined by

position of the plug in the

socket adapter.

of operations to lockout.

Operation

Counter

Records the cumulative

trip operations of the

control.

Sequence Relay

Steps the control through

its operating sequence.

Manual Control

Switch

In the TRIP position, it

locks out the control,

advances the sequence

relay to lockout, and dis-

connects the battery

from the control circuits.

In the CLOSE position, it

moves the sequence

relay to the home posi-

tion, reconnects the bat-

tery, and closes recloser.

If held in the CLOSE

position, it will override

cold-load inrush; how-

ever, the control will lock

out for permanent faults.

Non-Reclosing

Switch

Sets the control for one-

trip to lockout without dis-

turbing the lockout setting

of the operations selector.

Lamp Test Lockout

Switch

Enables testing the signal

lamp and checking for

Tie Board

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 conve-

nience accessories can be added to further expand and

enhance the application capabilities of the control.

Phase- and Ground-Trip Protective Feature

The phase- and ground-trip protective feature extends the

maximum fault-current capability of the ME control to the

maximum interrupting rating of the recloser.

The phase- and ground-trip protection feature consists of

four Zener diodes bracket-mounted to the back panel

alongside the tie board (shown in Figure 3).

Back Panel

The control battery, cabinet heater, surge module for

auxiliary power supply, customer connections terminal

strip, and accessory boards are located inside the control

cabinet and on the back panel of the control as shown in

Figure 4.

Description of Control Operation

Line current flowing through the recloser is sensed

by three internally mounted bushing-current transformers

in the recloser, one on each phase. When the phase cur-

rent 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 the

successful reclosing, 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 pro-

grammed 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. A set

of two individual timing curves provides dual timing for

both phase and ground.

A functional block diagram of the control operation is

shown in Figure 5. Line current conditions are monitored

continuously by three bushing-type current transformers

in the recloser, one on each phase. Output of these trans-

formers is fed to the trip network in the control, which

includes the minimum-trip resistors, isolation transform-

ers, and rectifier circuits.

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 two delayed operations:

The overcurrent signal is integrated with time on the char-

acteristic 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 to trip

open 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 current remains above the minimum-trip level, the trip-

ping—reclosing sequence of fast and delayed operations

is repeated, as programmed, to lockout.

If the overcurrent is cleared before the operating

sequence reaches lockout, the reset-delay circuit starts

timing when the recloser closes into the un-faulted 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 trips operating

sequence. However, should the fault recur before the

reset plug times out, the control will continue its operating

sequence where it left, and the reset delay timing will be

erased.

Ground-fault sensing and tripping operations occur

exactly the same as phase sensing and tripping, except

that zero-sequence (ground) current is sensed instead of

phase current. The ground-fault circuitry includes its own

minimum-trip 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 ground-trip modes of operation.

Control Battery

Power to operate the tripping and reclosing solenoids in

the recloser is provided by a 24 volt, nickel-cadmium bat-

tery located in the back, upper right corner of the control

cabinet. A temperature-regulated 120 Vac potential bat-

tery charger, built into the control circuitry, provides a tem-

perature compensated charging current to the battery. All

Form 3A controls require a 120 Vac input to the con-

trol to energize the battery charger.

If 120 Vac cannot be provided to the control, the recloser

must be equipped with a factory-installed battery charger

accessory.

A. In solenoid-operated reclosers (RVE, RXE, VWE,

VWVE27, VWVE38, WE, and VWE) a BCT accessory

must be added to the recloser to obtain charging

power from the line.

Note: Line current flow through the recloser must be a

minimum of 40 amps for at least 12 hours per day to

provide sufficient charging power.

B. In motor-operated reclosers (CXE, VSA12, VSA16,

VSA20, VSO12,VSO16, and VSML), a potential-type

battery charger accessory must be added to obtain

charging power from the 240 Vac auxiliary power

source of the recloser.

Battery Check Procedures

Follow the check battery procedures to check the battery

voltage, quiescent drain, and charging rate. The values in

the test procedure is based on testing at 25˚ C (77˚ F).

Note: The control does not need to be connected to a recloser

for the battery check tests.

Check Battery Voltage Procedure

1. Remove the control from service. Refer to the To

Remove Control from Service section in this manual.

2. Disable the control battery charger by opening the

fused switch or removing the AC power from the con-

trol. Wait 3 to 5 minutes to allow the battery voltage to

stabilize prior to testing the open circuit battery voltage.

3. Three battery test terminals in the lower right corner of

the front panel are used to check the battery voltage,

quiescent drain, and charging rate (Figure 6). The left

hand pair of terminals (V) are connected directly

across the battery to check battery voltage. The red

terminal (far left) is battery positive (+).

4. The battery in the control will experience a steady

drain of approximately 1.5–2.5 mA (may be as high as

4.5 mA with certain accessories).

5. Measure the battery voltage from the battery test ter-

minals on the control front panel. If battery voltage is

below 24 volts, the battery is either low on charge or

failing. The battery should be removed for recharging

and retested before returning to service.

6. If battery voltage is above 24 volts, perform the fol-

lowing load test. While measuring battery voltage,

connect a 10Ω, 10 watt resistor across the battery test

terminals for approximately 2–3 seconds. For ambient

temperatures above -6˚C (20˚F), battery voltage

should drop by no more than 3 volts from the open cir-

cuit voltage.

Note: Either a KA638ME voltmeter accessory or a KMET

Tester can be used for the load test. Both devices

have a built in 10Ωload resistor.

7. If the temperature is below -6˚C (20˚F), the battery

voltage/temperature should follow the lower curve in

Service Information S280-75-2 Figure 53. If the volt-

age falls below the lower curve, the battery should be

removed for bench testing.

SAFETY

FOR LIFE

CAUTION: Equipment damage. Shorting battery

positive to battery negative at the battery test ter-

minals on the control panel will cause damage to the

control. The control will be inoperative and possible

misoperation (unintentional operation of the recloser)

can result. T214.1

CAUTION: Recloser misoperation. The control

must be removed from service before disconnect-

ing the control battery. Disconnecting the control battery

from an in-service control may cause recloser misoper-

ation (unintentional operation). Failure to comply can

result in equipment damage and personal injury. T213.4

Battery Test Terminals.

86847KMA-D

IMPORTANT: Battery voltage and charge current

measurements can be made while the control is in ser-

vice, from the test terminals provided on the face of the

control panel. The control must be taken out of service

for all other battery maintenance, battery replacement,

or battery drain tests.

Check Battery Quiescent Drain and Charging

Rate Procedure

The righthand pair of terminals (-I-) are connected in

series with the negative battery lead to check quiescent

drain and charging rate. Proceed as follows:

1. Remove the control from service. Refer to the To

Remove the Control from Service procedure in the

Programming and Operating the Control section of

this manual.

2. Set the control to the home (reset) position by moving

manual operator to CLOSE.

3. Plug a dc milliammeter into the current test terminals.

Loosen both terminals slightly and disconnect the

shorting link from between terminals.

4. With the battery charger de-energized, current will

flow opposite to the direction shown by CHG. Under

normal conditions, quiescent drain will be 1-1⁄2 to 2 mA.

However, the shorter time reset plugs and certain

accessories can, as shown in Table 1, increase the

quiescent drain above nominal value.

Note: To verify the charge/discharge polarity of the test

meter, momentarily actuate the LAMP TEST/LOCK-

OUT TEST toggle switch to LAMP TEST. The dis-

charge current is measured.

5. With the battery charger energized, current will flow in

the direction shown by CHG. The charging circuit

used in the control is temperature regulated. The

charging rate will vary depending on the internal con-

trol temperature, see Figure 7.

6. Replace and tighten the shorting link between the cur-

rent terminals before removing the ammeter.

Note: Bypass diodes in the battery circuit prevent the control

from being disabled if the link is inadvertently left

open.

Temperature-Regulated Battery

Charger

All Form 3A Type ME controls, serial number 50070 and

above, are equipped with a temperature-regulated battery

charger as standard equipment.

Description

The temperature-regulated battery charger provides pro-

tection against battery drain and premature battery failure

at high ambient temperatures. As the temperature

increases, the self discharge rate of the control battery

increases. The temperature-regulated battery charger

compensates for this self-discharge by providing higher

charging rates at higher temperatures.

Operation

The temperature-regulated battery charger consists of a

charger ballast-surge protection card and a plug-in battery

charger circuit board. It provides an increased charging

rate proportional to the temperature inside the control cab-

inet (see Figure 7).

IMPORTANT

Beginning with control serial number 53381, the key

slot position of the battery charging board socket has

been changed. The key slot on the temperature-regu-

lated charging board (MEA1172, 120/240 Vac) has

been moved to match the socket arrangement. The

new charging board can be identified by the revision 6

or above marking adjacent to the part number. A blue

label affixed to the accessory list location guide label,

inside the control door, identifies the new temperature-

regulated battery charging board.

Note: Controls equipped with CT or potential charger in the

recloser are unaffected by this change. They will

continue to use the MEA 388-1 charging board, with

the key in the original position.

trol must be removed from service prior to making any

changes to programmed settings.

The plug-in components and selector switches for pro-

gramming the control are located on the black, upper por-

tion of the control panel.

To Remove the Control

from Service

Prior to changing plug-in components, performing control

maintainence, making programming changes, or replac-

ing the battery on an in-service control, the following

steps must be taken to prevent possible recloser misop-

eration.

1. Switch Ground Trip Block switch to BLOCK.

2. Disconnect control cable from control.

3. De-energize potential battery charger, by opening the

battery charger fuse block switch (shown in Figure 4).

4. Operate the Manual Control switch to OPEN.

5. Unplug the control battery.

To Return the Control to Service

After required work is completed, return the control to ser-

vice with the following steps:

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

trol settings are correct.

2. Connect control battery.

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

gize the potential battery charger.

4. Move Manual Control switch to CLOSE, to ensure that

control is reset to the home position.

5. Reconnect the control cable to the control.

6. Switch Ground Trip Block switch to NORMAL.

Number of Operations Selectors

The three selector knobs in the upper left corner of the

panel (Figure 8) establish the operating sequence of the

control. From one to four total operations to lockout can

be selected on the center LOCKOUT knob. GROUND

TRIP SOCKET 1 selector knob to the left establishes the

number of ground trip operations (0 to 4) according to the

time–current characteristic curve of the timing plug in

GROUND TRIP SOCKET 1 . The balance of the ground-

trip operations to lockout are then performed according to

the characteristic curve of the timing plug in GROUND

TRIP TIMING SOCKET 2 .

PHASE TRIP SOCKET 1 selector knob to the right per-

forms the same function for phase-trip sequence selection.

Reclosing Interval Timing Delay

Selectors

Depending upon the number of operations to lockout,

one, two, or three reclosing intervals (each individually

timed) can be programmed. The reclosing intervals are

established by the solid-state timing plugs in the upper

right corner of the panel (Figure 9). Times of 1, 2, 5, 7, 10,

15, 30, and 45 seconds are available on a multiple-setting

plug (Figure 9). The small white arrow at the top of the

plug indicates the value selected. Selection is determined

by the position of the plug in the socket adapter (Figure

10). INST (instantaneous) and 60 second, single-value

plugs are also available. Single value plugs do not use the

socket adapter.

The INST reclosing interval plug may be used only in the

first reclosing interval socket. The instantaneous reclos-

ing interval time will vary depending upon the recloser on

which the control is used; the approximate values are:

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

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

RVE, RXE, VWE, VWVE27, VWVE38, WE,

WVE reclosers .................................................... .67 sec.

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

The INST reclosing interval plug must not be used with

the Type VSO recloser. No reclosing interval shorter

than 1⁄2 second should be programmed into the Type ME

control when it is used with the Type VSO recloser. A 1⁄2

second reclose plug is available (ordered by KA1177ME-

1). If an instantaneous (INST) plug is used for the first

reclosing interval, it will result in a 12 cycle reclosing time,

which may be too short to permit arc deionization at the

fault location.

Minimum-Trip Resistor

Cartridges

The recloser minimum-trip current ratings are established

with the plug-in resistor cartridges in the center of the con-

trol panel. The cartridges, labeled with their minimum-trip-

current values, are identified for GROUND TRIP (one

required), or PHASE TRIP (three required). All three

phase-trip cartridges should have the same current rating.

All Kyle electronic reclosers, except VSA20, VS020, and

discontinued Types ME and VSMT, use a yellow label

minimum-trip resistor cartridge. Blue label cartridges are

used with 2000:1 sensing CTs in the higher current rated

VSA20 and VS020 reclosers and are not interchangeable

with yellow label resistors.

800, 960, 1120, 1200, 1360, 1600, 1920,and 2240

amps.

Ground- and Phase-Trip Timing

Plugs

Time-current curves for both phase and ground tripping

are established by the four plugs along the right edge of

the control panel (Figure 11). Individual plugs for 20

phase-trip timing curves and 16 ground-trip timing curves

are available. (See Reference Data TCC Index R280-91

for time-current curves).

When dual-timing operation is programmed, the timing

characteristic curve in Socket 1 always precedes the

curve in Socket 2. When single-timing operation is pro-

grammed, the timing plug is installed in Socket 2 and the

number of fast operations selector knob is set on zero.

Reset Delay Selector

For temporary faults that are cleared before lockout

occurs, reset timing starts after a successful reclosure

(current is below minimum trip). The reset time is estab-

lished by a timing plug similar to, but not interchangeable

with, the reclosing interval plug. The reset delay plug (Fig-

ure 12) is located on the lower right hand portion of the

control panel. Times of 10, 15, 30, 45, 60, 90, 120, and

180 seconds are available on a multiple setting plug and

are determined by the position of the plug in the socket

adapter (Figure 10). A 20 second, single-value plug is

also available.

Note: The selected reset delay time must be longer than the

longest reclosing interval of any load- or source-side pro-

tective device with which the recloser is to coordinate.

CAUTION: Recloser misoperation. Socket 2

must always be provided with a timing plug; other-

wise phase tripping is blocked and ground tripping may

be instantaneous. T218.1

SAFETY

FOR LIFE

Reset Timed from First

Trip Operation

The Form 3A control can be converted to reset-timed-

from-first-trip operation, if so desired, by removing a

jumper on the tie board and moving a lead from the push-

on tab labeled RECLOSE to an adjacent tab labeled

HOME (Figure 13). However, under this reset mode, the

time selected must exceed the longest possible tripping

and reclosing sequence that can be experienced. Mini-

mum-fault currents (which provide the longest tripping

times) must be considered.

Operating Switches and

Indicators

The switches and indicators for manual operation and

service are grouped on the lower, light colored portion of

the control panel (Figure 14).

Manual Control Switch

Located in the center of the lower panel, the manual con-

trol switch enables manual closing and tripping of the

recloser. Moving the switch to TRIP opens the recloser,

locks out the control, and disconnects the battery from the

control circuits. Moving the switch to CLOSE reconnects

the battery, resets the control to home, and closes the

recloser.

A cold-load pickup feature is built into this switch. Holding

the switch in CLOSE will disconnect the no. 1 timing plug

for both phase and ground trip and set the control to oper-

ate on the slower no. 2 plugs. While the switch is held in

this position, the control is still free to trip and lock out if

closed into a fault. However, all operations to lockout will

occur on the no. 2 trip-timing plugs.

Ground-Trip Operation Switch

The ground-trip operation of the control is disabled when

this switch is set to BLOCK. Blocking ground-trip opera-

tions is useful during known periods of three-phase load

unbalance and while performing single-phase testing or

switching.

Non-Reclosing/Normal Reclosing

Switch

To meet specific local safety requirements during startup

or service restoration, the control can be set to block

reclosing after an automatic trip (one-shot-to-lockout-

operation) by setting the operating mode switch to NON-

RECLOSING. Returning this switch to NORMAL

RECLOSING after a successful reclose will ready the

control for its full programmed operating sequence.

WARNING: This equipment is not intended to

protect human life. Follow all locally approved pro-

cedures and safety practices when installing or operat-

ing this equipment. Failure to comply can result in death,

severe personal injury and equipment damage.

G102.1

Lockout Indicator

Verification of control lockout consists of an indicator lamp

and a momentary double-throw toggle switch. In the

LOCKOUT TEST position, the lamp will light if the control

is locked out; the LAMP TEST position verifies the condi-

tion of the lamp.

Proper verification of the recloser status must include

examination of both the control lockout indicator and a

visual check of the position of the mechanical contact

position indicator on the recloser.

Battery Terminals

These terminals provide a means for checking the condi-

tion of the battery. Refer to the Battery Check Proce-

dures in the Control Battery section in this manual.

Closing Coil Control 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 motor-operated 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.

Note: In 1988, Buss redesigned the MDL-2.5 amp fuse that is

used on controls shipped with reclosers having "quick-

close" mechanisms such as Type VSO 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 ver-

sion 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-2.5 amp fuse and the

MDQ-2.5 amp fuse are acceptable for this application.

Form 3A Type ME Electronic Control Installation, Operation, and Testing Instructions

IMPORTANT: The lockout indicator will only accu-

rately reflect the state of the control. It does not monitor

the recloser mechanism and may not accurately reflect

the position of the recloser contacts.

IMPORTANT: Use only Buss Type MDQ-3/8 amp

fuses. Until 1988, 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 clos-

ing coil control fuse will result in unnecessary fuse oper-

ation and prevent the recloser from closing.

This control is used in conjunction with a Kyle electroni-

cally controlled recloser. Installation instructions for the

recloser are packed with the recloser. Refer to the appro-

priate recloser installation manual when installing the con-

trol and recloser.

Mounting the Control

The Form 3A Type ME electronic recloser control can be

mounted at any convenient, accessible location near, or

remote from, the recloser.

1. For pole-mounted installations, this is normally near

the base of the pole.

2. For substation installations, brackets are available as

a mounting frame accessory for mounting the control

to the substation frame.

Limits on control cable length determine the maximum

distance between the control and recloser: up to 125 feet

for solenoid-operated reclosers RVE, RXE, VWVE27,

VWVE38, WE, WVE; up to 35 feet for motor-operated

reclosers CXE, VSA12, VSA16, VSA20, and VSML.

Grounding the Control

The control cabinet must be grounded. A grounding con-

nector on the underside of the cabinet will accommodate

no. 14 solid through no. 4 stranded conductors. (Figures

15 and 16). Be sure to follow all locally approved ground-

ing procedures when installing the control. Suggested

methods for grounding the control are shown in Figures

17 and 18.

The installation must meet the following requirements:

1. The recloser and transformer are protected with light-

ning arresters.

2. The transformer tank is grounded.

3. The recloser head is grounded.

4. Secondary cables must be shielded or Triplex cables.

Note: If the control is mounted on a recloser frame which

itself is grounded, a separate lead from the cabinet

to earth ground is not required but may be added.

Control Cable

A 7 ft. cable is furnished as standard with the control-

recloser package. This length is sufficient for most sub-

station mounting frame installations. For other

installations, cable lengths as specified on the order are

provided.

The cable is fabricated with connectors which mate with

the female receptacle of the recloser on one end and the

male receptacle of the control on the other.

Note: The control cable must be supported along its length to

prevent repeated movement due to wind or other out-

side forces which can damage the cable.

Shielding and Surge Protection

of Remote Cables

All remote operation and control monitor leads should be

protected within shielded cables. This is particularly

important if the remote cables are routed near other

cables or devices that emit strong magnetic fields. The

cable shield must be grounded at the Form 3A control

only, see Figure 19.

Note: In order to protect a remote device(s) from high-voltage

surges, all remote operation and monitor leads must be

protected with metal oxide varistors (MOV's), see Figure 19.

Use Harris V320LA40B varistors, (320 Vac, 160 J), or

equivalent.

Customer Connections Terminal

Strip

All Form 3A controls require 120 Vac auxiliary power to

operate the battery charger and energize the control cab-

inet heater; both are standard features of the control.

Auxiliary power connections and connections for remote

operation of certain accessories are made on a 14 point

terminal strip mounted vertically on the back panel of the

control. Figure 20 shows two partial detail views of the ter-

minal strip to indicate the customary connection terminals

for the various accessories. However, deviations may

occur to accomodate certain combinations of acces-

sories. All terminals for required connections are clearly

marked.

The minus side of the 24 Vdc control circuit is grounded to

the cabinet at the input cable receptacle card in the bot-

tom of the cabinet by a white jumper lead connected

between tabs GND and BATT-. When an external dc

power source accessory is used instead of the battery,

remove the jumper to make sure there is no interaction

between station ground and earth ground.

Note: A 27 ohm resistor on the receptacle card, in series with

the grounding jumper lead, will limit the short-circuit cur-

rent to nondestructive levels in case of momentary acci-

dental grounding of the plus side of the circuit. A

sustained short will cause the resistor to overheat and

eventually burn out. This condition, however, will not

affect control operation.

Form 3A Type ME Electronic Control Installation, Operation, and Testing Instructions

Control / Recloser

Interchangeability

Since a temperature-regulated, 120 Vac, potential-type

battery charger is a standard feature of the Form 3A elec-

tronic control, the battery charger is not included as a

standard feature of the companion electronically con-

trolled reclosers. It is, however, available as a factory

installed accessory for these reclosers. Care must be

exercised when interchanging "new-style" controls (Form

3A) and "old style" controls (Form 3) with "new style"

reclosers (without battery recharger) and "old style"

reclosers (with battery charger as standard) to make sure

that each combination has an operational battery charger.

The Form 3A control, or the Form 3 control equipped with

a battery charger accessory, is compatible with all old-

and new-style reclosers provided 120 Vac power is avail-

able at the control.

If 120 Vac is not available at the control, the Form 3A con-

trol can be made compatible with any old-style recloser by

changing the connections on the input receptacle card as

shown in Figure 21 to connect the battery charger in the

recloser to the control.

If 120 Vac is not available at the control, the new-style

recloser must be equipped with its battery charger acces-

sory to be compatible with the Form 3A control. The com-

bination of a Form 3 control, without the battery charger

accessory, and a new-style recloser does not have an

operational battery charger. To make this combination

compatible, either the control or the recloser must be

equipped with its battery charger accessory (depending

on whether 120 Vac is or is not available at the control).

Tables 2 and 3 summarize the various recloser/control

combinations.

CAUTION: Equipment damage. Each remote

operation accessory installed in the control requires

two wires for operation. For example, if both remote

close and remote lockout are installed, they require four

wires. Using three wires will cause misoperation and/or

control damage. T220.0

IMPORTANT: Although it may be desirable under

certain conditions to operate control accessories in par-

allel from a single remote contact, this is generally not

possible. Cooper Power Systems does not advise inter-

connection between controls because of possible con-

trol interaction.

Testing with Type MET Tester

The Kyle Type MET Electronic Recloser Control Tester

(Figure 23) has been designed specifically for testing

Form 3A controls. The MET Tester is completely self-con-

tained, includes all necessary metering and interconnect-

ing cables, and is capable of performing all required

checks and tests from a simple verification of operation to

a complete verification of operation of all operating

parameters. Operating instructions for the Type MET

Tester are contained in Service Information S280-76-1.

If an MET Tester is not available, the following test pro-

cedures, ranging in complexity from a simple check of

coordinated control-recloser operation to a verification of

the various control settings, may be performed:

•For a simple check of coordinated control-recloser

operation, the output of a soldering gun (with the tip

removed) connected across a minimum-trip resistor

will provide a signal of sufficient strength to simulate a

fault current and operate the control. Refer to the Sol-

dering-Gun Test section in this manual.

•To verify minimum trip, timing, and operating

sequence, an equivalent test current which simulates

the output of the sensing CTs can be introduced

directly into the control. Refer to the Testing with

Simulated Current section of this manual.

•To verify the control settings and check the sensing

CTs, a variable, low-voltage test current simulating

fault conditions can be passed through one phase of

the recloser. Refer to the Testing with Low-Volt-

age Current section of this manual.

Testing an Installed Control

A recloser control can be taken out of service for testing

and placed back in service without deenergizing its

recloser and interrupting the system. However, during the

time the control is out of service, system fault protection

is lost.

To Remove Control from Service

Prior to testing, changing plug-in components, performing

control maintenance, making program changes, or bat-

tery replacement on an in-service control, the following

steps must be taken to prevent possible recloser misop-

eration.

1. Switch Ground Trip Block switch to BLOCK.

2. Disconnect control cable from control.

3. De-energize potential battery charger, by opening the

battery charger fuse block switch (shown in Figure 4.)

4. Operate the Manual Control switch to OPEN.

5. Unplug the control battery.

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

trol settings are correct.

2. Connect control battery.

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

gize the potential battery charger.

4. Move Manual Control switch to CLOSE, to ensure that

control is reset to the home position.

5. Reconnect control cable to control.

6. Switch Ground Trip Block switch to NORMAL.

Closing the Recloser

Electrical Closing - RVE, RXE, VWE,

VWVE27, VWVE38, WE, and WVE

Reclosers

For automatic operation, line voltage is required to oper-

ate the closing solenoid of RVE, RXE, VWE, VWVE27,

VWVE38, WE, and WVE reclosers (except for reclosers

equipped with the low voltage closing accessory).

For on-line testing, bypass the recloser, open the load-

side disconnects, but keep the source-side disconnects

closed. This will remove the recloser from service, but will

keep line voltage supplied to the closing solenoid. See

Figure 24.

WARNING: Hazardous voltage. Interconnect

source leads X and Y and ground solidly to the

recloser tank. Do not connect lead Z to any other phase

or mechanical ground. Dangerous voltages to ground

exist on the phase connected to lead Z. Solidly ground

all equipment. Failure to comply can result in severe

personal injury and/or equipment damage. T224.1

For shop testing, the closing solenoid voltage can be

supplied by back-feeding a transformer with a low-side

rating equal to the voltage rating of an available power

source and a high-side rating equal to the voltage rating

of the recloser. This procedure is not to be used on

reclosers equipped with the low-voltage closing acces-

sory, see Figure 25. Make sure the solenoid coil operating

voltage is maintained at the recloser bushings during the

two-to-three cycle interval the closing coil is energized. In

general, a 75 kVA transformer of the proper voltage rating

with an impedance drop of about 3% will be satisfactory.

The source impedance must also be reasonably low. The

closing coil requirement is approximately 200 kVA during

the two-to-three cycle closing operation.

Electrical Closing - CXE, VSA, VSO,

and VSML Reclosers

CXE, ME, VSA, VSO, and VSML reclosers utilize a motor-

operated closing mechanism which is energized from a

230 Vac power source; no high-voltage is required.

Manual Closing - Solenoid-Operated

Reclosers

If high-voltage for operating the closing solenoid of RVE,

RXE, VWE, VWVE27, VWVE38, WE, and WVE reclosers

is not available, manual closing can be substituted for

electrical closing; however, not all control settings can be

checked since manual closing is not synchronized with

the closing coil control circuit in the control.

To manually close the recloser:

1. Remove the closing tool port cover and gasket from

the side of the recloser head casting.

2. Insert the KA90R T-handled tool (available as an

accessory) into the port, engaging the pin on the clos-

ing shaft. (Figure 26).

3. Close the recloser by placing the yellow operating

handle (under the sleet hood) into the up or CLOSED

position and turning the closing tool one-quarter turn

clockwise.

4. After each trip operation, about 1⁄2second will elapse

while the closing solenoid plunger is moving upward to

reset the main toggle latch.

5. After the main toggle latch resets, the recloser can be

closed again by operating the manual closing tool.

6. Replace the gasket and port cover on the recloser

head after testing has been completed.

7. Reinstall the control closing coil fuse.

Soldering-Gun Test

The output of a soldering gun (Weller Model 550 or equiv-

alent) will produce a signal of sufficient strength to simu-

late a fault and check recloser-control operation. To

solder-gun test a control:

1. Set the Non-Reclose/Normal Reclose switch on the

control to NORMAL reclosing and the Ground Trip

Block switch to NORMAL.

2. Move the manual control switch on the control panel to

TRIP, to open the recloser contacts.

3. Remove the tip from the posts of the soldering gun by

loosening the hexagonal locking nuts.

4. Connect a short clip lead to each post and connect the

soldering gun across the Phase A minimum trip resis-

tor as shown in Figure 27.

5. Move the manual control switch on the control panel to

CLOSE. The recloser should close.

6. Energize the soldering gun by depressing and holding

the trigger until the recloser trips.

7. Immediately release the trigger to prevent instantan-

ious trips on succeeding reclosings.

8. When the recloser recloses, again energize the sol-

dering gun and repeat Steps 5 and 6 until the control

locks out. Count the number of fast and delayed trip

operations and compare the count with the control set-

tings. Verify lockout with the switch on the operator

panel.

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

WARNING: Explosion Hazard. Excessive Con-

tact Arcing. Do not use the manual closing tool to

close an oil-insulated energized recloser. Closing an

energized oil-insulated recloser with a manual closing

tool can cause excessive contact arcing, rapid build-up

of gas within the equipment, and possible explosion that

can cause death, severe personal injury, and equip-

ment damage. T203.2

CAUTION: Equipment damage. Do not turn the

manual closing tool more than one-quarter turn

clockwise. Forcing the tool beyond the mechanism stop

may shear the pin on the closing shaft of the recloser.T222.0

IMPORTANT: If manual closing is not performed

within the reclosing interval of the control, the closing

coil control fuse will blow. To prevent this from occuring,

remove the fuse during manual closing procedures.

Testing with Simulated Current

The Form 3A electronic recloser control continuously

monitors line current conditions with three wye-con-

nected 1000:1 ratio current transformers mounted inter-

nally on the source-side bushings of the recloser. These

CTs are connected directly to three wye-connected

phase minimum-trip resistors on the control panel. A

fourth resistor (ground trip) is connected in the CT neutral

to monitor zero-sequence current flow.

The current through any one of the minimum-trip resistors

is 1/1000 of the line current. Therefore, if 1/1000 of the

line current is applied directly to the resistor, the control

will operate as if line current was flowing through the CT

primary and one milliamp of test current will be equivalent

to one amp of line current.

Note: The above applies to all but the VSA20, VSO20 and the

discontinued Type ME and VSMT reclosers. These

higher continuous-current-rated reclosers use 2000:1

ratio sensing CTs and special blue label minimum-trip

resistors. For Type VSA20 AND VSO20 reclosers, one

milliamp of test current is equivalent to two amps of line

current. When testing controls equipped with blue label

trip resistors, double the milliamp reading to obtain the

equivalent line current.

Test Equipment

A test circuit to produce a variable output in equivalent

amps is shown in Figure 28. This circuit will provide a

fairly complete test of the control and recloser. All parts

are standard and can be purchased through any elec-

tronics supply outlet.

Note: High voltage is required to operate the closing solenoid

of Type RVE, RXE, VWE, VWVE27, VWVE38, WE, and

WVE reclosers, unless they are equipped with the low

voltage closing accessory. A 240 Vac power source is

required to operate the motor of CXE, VSA, VSO, and

VSML Reclosers. Various closing schemes are dis-

cribed in the Closing the Recloser section.

Test Procedure

Coordinated Operation of Control and

Recloser

1. Make certain that closing power is available at the

recloser.

A. On solenoid-operated reclosers, move the yellow

manual operating handle (located under the sleet

hood) to the up position.

B. On motor-operated reclosers, move the TRIP-

RESET lever or rod (located in the recloser opera-

tor cabinet) to RESET.

2. Set the operating mode switch on the control to NOR-

MAL reclosing and the ground trip switch to NOR-

MAL.

3. Move the manual control switch on the control panel

to CLOSE. The recloser should close.

4. Move the manual control switch on the control panel

to TRIP. The recloser should open.

Simulated Current Test Circuit.

Minimum-Trip Current

The minimum-trip current test should be performed on a

fast time–current curve operation. The test will produce

misleading results if the control is operating on a delayed

TCC curve.

Note: If the control is equipped with the KA418ME7 sequence

coordination accessory, refer to Service Information

S280-75-37 for additional information.

To test minimum-trip current:

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

recloser.

2. Connect the output of the test circuit across the Phase

A minimum trip resistor.

3. While holding fault switch S1 on the tester closed,

slowly raise the test current from zero and note the

meter reading when the recloser trips. This reading in

milliamps should correspond to the trip resistor value

in amps. For example, a 280 amp resistor should trip

at 280 mA.

4. Release S1 before the recloser automatically recloses

to prevent instantaneous trips on succeeding reclos-

ings.

5. Repeat steps 1 through 4 for the Phase B, Phase C,

and Ground trip resistors.

Trip Time

The trip times of the fast timing plugs (Sockets 1 and 1 ),

are ordinarily too fast to check with a stopwatch with any

accuracy. However, the delayed timing plugs (Sockets

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

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

recloser.

2Remove the RESET DELAY plug from the control

panel.

3. Connect the output of the test circuit across the Phase

A minimum trip resistor.

4. While holding Fault switch S1 closed, adjust the out-

put to produce an equivalent test current of at least

150% of minimum trip. For example, a 420 mA test

current for a 280 amp resistor.

5. Release S1 and move the manual control switch to

CLOSE to close the recloser.

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

7. Release S1 immediately and allow the recloser to

close automatically.

8. Repeat Steps 6 and 7 for all fast operations to

advance control operation to the delayed time-current

curve.

Note: The number of fast operations is determined

by the setting of GROUND TRIP SOCKET 1

and PHASE TRIP SOCKET 1 switches in

the upper left corner of the panel.

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

10. When the recloser trips, stop the watch and release

S1. Compare the time to the time at 150% of minimum

trip on the published time–current curve for the timing

plug being checked. For example, a B plug will clear in

about 2.8 seconds at 150% minimum trip.

11. Repeat Steps 9 and 10 to lockout.

12. Repeat Steps 3 through 11 for the GROUND TRIP

TIMING Plug 2 .

Reclosing Time

To check reclosing time (the open interval of the recloser

between trips):

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

2. With the tester output connected across any one of

the minimum-trip resistors and adjusted to produce an

eqivalent test current of at least 150% of the minimum

trip rating, close Fault Switch S1.

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

the interval the recloser is open, stopping when the

recloser recloses. The time should correspond to the

first RECLOSING INTERVAL DELAY plug setting.

4. Repeat Steps 2 and 3 to check the timing of the sec-

ond and third RECLOSING INTERVAL DELAY plugs.

5. Replace the RESET PLUG on the control panel.

Reset Time – Timed from Successful

Reclosure

Reset timed from a successful reclosure is standard on

the Type ME Form 3A control. To check the reset time:

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

recloser.

2. With the tester output connnected across any one of

the minimum-trip resistors and adjusted to produce an

equvalent test current of at least 150% of the min-

imun-trip rating, close Fault Switch S1.

3. When the recloser trips, release S1 and wait for the

recloser to reclose automatically.

4. Start timing when the recloser closes and stop when

the control resets automatically as indicated by an

audible clicking as the sequence relay returns to home

position.

5. The elapsed time should correspond to the setting of

the RESET DELAY plug.

Form 3A Type ME Electronic Control Installation, Operation, and Testing Instructions

Reset Time-Timed From First Trip

Operation

The Form 3A control can be converted to reset-timed-

from-first-trip operation as described in the Reset Delay

Selector section.

To check the timing of this reset mode:

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

recloser.

2. With the tester output connected across any one of

the minimum-trip resistors and adjusted to produce an

equivalent test current of at least 150% of the mini-

mum-trip rating of the resistor, close Fault Switch S1.

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

4. Continue timing after the recloser automatically

recloses until the control resets automatically as indi-

cated by an audible clicking as the sequence relay

returns to its home position.

5. The elapsed time should correspond to the setting of

the RESET DELAY plug.

Operation of the Non-Reclosing

Switch

The non-reclosing switch provides one-trip-to-lockout

capability without disturbing the normal operating

sequence of the control. To check its operation:

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

2. Move the manual control switch to CLOSE to close the

recloser.

3. With the tester output connected across any one of

the minimum-trip resistors and adjusted to produce an

equivalent test current of at least 150% of the mini-

mum-trip rating of the resistor, close Fault Switch S1.

4. The recloser should trip once and not reclose. The

control should indicate lockout position when the

LOCKOUT TEST switch is operated.

Testing with Low-Voltage

Current

The Form 3A recloser control-with its recloser-can be

tested with a variable low-voltage current passing through

one phase to simulate fault conditions.

Test Equipment RVE, RXE, VWE,

VWVE27, VWVE38, WE, AND WVE

Reclosers

A test circuit for these solenoid-closed reclosers is shown

in Figure 25. The following equipment is required for the

recommended test setup:

Note: Solenoid-closed reclosers equipped with a 120- or 240-

Vac low-voltage closing coil accessory can be tested as

shown in Figure 29.

•Variable Autotransformer T1, 230 volts, 20 amps.

•Low-Voltage transformer T2 to simulate fault conditions.

Ratio and size will depend upon the maximum current

to be used. The recloser presents a low impedance to

the transformer, so secondary voltage must be only

high enough to force the required current through the

secondary of the transformer and the recloser.

Note: An alternative method of providing the necessary

current through the transformer is shown in Figure

30.

•High-Voltage T3 to operate the closing solenoid. Refer

to the Closing the Recloser section for high voltage

transformer requirements.

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

•Current-actuated timer or stopwatch.

Test Procedure

Test Current Applied to Phase A

1. Assemble and connect the equipment as shown in

Figure 25, which shows the test current being applied

to Phase A, the phase nearest the sleet hood.

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

3. Move the yellow manual operating handle, located

under the sleet hood, to the UP position.

4. Set the Non-Reclosing/Normal Reclosing switch on

the control panel to NORMAL RECLOSING and the

Ground Trip switch to BLOCK.

5. Move the manual control switch to CLOSE. The

recloser should close, indicating correct operation of

the control and recloser.

6. Move the manual control switch to TRIP. The recloser

should open, verifying the electrical operation of the

trip solenoid and the mechanical operation of the trip

mechanism.

Test Procedure

Test Current Applied to Phase B and C

1. De-energize the high-voltage closing source and

close the recloser manually before testing phase B

and C. Refer to the Manual Closing procedure in the

Closing the Recloser section of this manual.

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

3. Move the yellow manual operating handle, located

under the sleet hood, to the UP position.

4. Set the Non-Reclosing/Normal Reclosing switch on

the control panel to NORMAL RECLOSING and the

Ground Trip switch to BLOCK.

5. Move the manual control switch to CLOSE. The

recloser should close, indicating correct operation of

the control and recloser.

6. Move the manual control switch to TRIP. The recloser

should open, verifying the electrical operation of the

trip solenoid and the mechanical operation of the trip

mechanism.

Test Equipment CXE, VSA, VSO, and

VSML Reclosers

A test circuit for these motor-operated reclosers is shown

in Figure 29. Since these reclosers require only a 240 Vac

source for closing, High-Voltage Transformer T3 and its

associated protective cage is eliminated, but all other

equipment is the same as the test equipment shown in

Figure 25.

Test Procedure

Coordinated Operation of Control and Recloser

1. Assemble and connect the equipment as shown in

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

3. Move the TRIP-RESET lever or rod, located in the

recloser operator cabinet, to RESET.

4. Set the Non-Reclosing/Normal Reclosing switch on

the control panel to NORMAL RECLOSING and the

Ground Trip switch to BLOCK.

5. Move the manual control switch to CLOSE. The

recloser should close, indicating correct operation of

the control and recloser.

6. Move the manual control switch to TRIP. The recloser

should open, verifying the electrical operation of the

trip solenoid and the mechanical operation of the trip

mechanism.

Minimum-Trip Current

The minimum-trip test should be performed on a fast

time–current curve. The test will produce misleading

results if the control is operating on a delayed time–

current curve.

Note: If the control is equipped with the KA418ME7 sequence

coordination accessory, refer to Service Information

S280-75-37 for additional information.

To test the minimum-trip current:

1. Move the manual control switch to CLOSE to close

the recloser.

2. With the test circuit connected to Phase A, energize

T1, slowly raise the test current from zero, and note

the meter reading when the recloser trips. This read-

ing should correspond to the minimum current rating

of the Phase A trip resistor.

3. After the recloser trips, turn T1 back to zero and move

the manual control switch to TRIP to lockout the

recloser.

4. Repeat Steps 1 through 3 for Phase B and Phase C

trip resistors.

5. To check the minimum ground-trip resistor, place the

ground-trip switch to NORMAL and repeat Steps 1

through 3.

Note: The single-phase fault test current will appear as a

phase-to-ground fault to the control. Therefore, when

checking ground settings, jumper the minimum-trip resis-

tor of the energized phase to block phase-trip operations.

Trip Time

If an electrically operated timer is used, both the fast and

delayed time–current curves can be checked; however,

the trip times of the fast timing plugs (sockets 1 and 1 )

are ordinarily too fast to check with a stop watch with any

reasonable accuracy. To check the trip times:

1. Move the manual control switch to CLOSE to close

the recloser.

2. With the ground-trip switch set on BLOCK, connect a

short clip lead across the minimum-trip resistor of the

phase being tested to prevent tripping of the recloser

while the test current is being adjusted.

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

mum-trip rating.

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

5. Remove the jumper from across the minimum-trip

resistor.

6. Keeping T1 at the desired setting, energize T1 and

record the tripping times as the recloser operates

to lockout. These times should correspond to the

times at 150% of minimum-trip on the published

time–current curves for the timing plugs being

checked. Delayed times can be measured with a stop-

watch.

7. To check the ground-trip timing plugs, place the

ground-trip switch to NORMAL and repeat Steps 1

through 6.

Note: The single-phase fault test current will appear as a

phase-to-ground fault to the control. Therefore,

when checking ground settings, jumper to the mini-

mum-trip resistor of the energized phase to block

phase-trip operations.

8. Return the ground-trip switch to BLOCK after the test

has been completed.

S280-75-1

SAFETY

FOR LIFE

IMPORTANT: Before checking the Phase B and

Phase C trip resistors on solenoid-operating reclosers,

de-energize the high-voltage closing source and close

the recloser manually. Refer to the Manual Closing of

the Closing the Reclosers section of this manual.

Reclosing Time

To check reclosing time, which is the open interval of the

recloser between trips:

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

recloser.

2. Energize T1 and adjust T1 to produce a current in

excess of the phase minimum-trip value.

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

recloser recloses.

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

manner.

5. The times should correspond to the first, second, and

third RECLOSING INTERVAL DELAY plug settings,

respectively.

Reset Time Timed from Successful

Reclosure

Reset timed from successful reclosure is standard on the

Type ME Form 3A control. To check the reset time:

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

recloser.

2. With T1 adjusted to produce a current in excess of the

minimum-trip value, energize T1.

3. When the recloser trips, deenergize T1 and wait for

the recloser to reclose automatically.

4. Start timing when the recloser recloses and stop tim-

ing when the control resets automatically as indicated

by an audible clicking as the sequence relay returns to

the home position.

5. The elapsed time should correspond to the setting of

the RESET DELAY PLUG.

Operation of the Non-Reclosing

Switch

The non-reclosing switch provides one-trip-to-lockout

capability without disturbing the normal operating

sequence setting of the control. To check its operation:

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

2. Move the manual control switch to CLOSE to close the

recloser.

3. With T1 adjusted to produce a current in excess of the

minimum-trip value, energize T1.

4. The recloser should trip once, and the control should

indicate lockout position when the LOCKOUT TEST

switch is operated.

Testing RVE, RXE, VWE, VWVE27,

VWVE38, WE, and WVE Reclosers with

Manual Closing

Testing procedures for minimum-trip current, time–current

curve time, reset time timed for successful reclose, reset

time timed from first operation, and operation of the non-

reclosing switch are the same as testing per the Testing

with Simulated Current procedure section except for

Type RVE, RXE, VWE, VWVE27, VWVE38, WE, and WVE

reclosers. These reclosers will not close automatically.

They must be manually closed after each trip operation.

For the Manual Closing Procedure, refer to the Closing

the Recloser section of this manual.

When testing reclosers with manual closing, the following

additional precautions must also be observed:

1. Since manual closing is not synchronized with the

closing coil control circuit in the control, the control

fuse will blow if manual closing is not performed within

the reclosing interval. To prevent damage, remove the

fuse during testing.

2. If the control is operating in the reset-after-first-trip

mode, the reset-delay plug may be removed from the

control for all testing except reset time timed from suc-

cessful reclose and reset time timed from first opera-

tion. If the reset-delay plug is not removed, the control

may reset before a test sequence is completed

because of the possible delays between trip opera-

tions when manual reclosing is used.

3. The variable autotransformer must be kept energized

at the proper setting while the recloser is closed man-

ually. Setting it properly before manual reclosing is ini-

tiated assures accurate timing values.
