3.0 INSPECTION AND PRE-INSTALLATION SET UP

Several inspection and pre-installation setup steps should be performed at this time to assure

future trouble free operation and to allow the worker to become familiar with the controls and

functions.

The BT-D unit is shipped in a carton fully assembled with the mounting channel, decoupler and

safety cover in place. The unit is shipped with the output shaft in the closed position, set for 90°

of rotation turning clockwise to open as viewed from above unless specified otherwise by the

customer. Rotation travel and direction are easily changed in the field. The battery is in place, but

the fuse is removed and stored separately.

3.1 INITIAL INSPECTION

Upon receiving the unit, open and inspect the carton and its contents. Report any shipping

damage to the delivering carrier. Record the nameplate data on page 2.

3.2 CHECK BATTERY

Check the battery voltage with a voltmeter to make sure that it is healthy. If it is less than 12.4 volts,

the battery may already be damaged beyond repair. Contact the factory. Refer to section 7.0 -

ADMO™ BATTERY CARE AND STORAGE.

3.3 CHECK PLUG-IN CONNECTORS

Check and make sure that all plug-in connectors are fully seated before testing the motor.

3.4 TEST MOTOR OPERATION

Install the battery fuse in the fuse block. The fuse is found taped to the main battery cable. A spare

fuse will be clipped to the inside of the enclosure door.

NOTE: Wait five minutes for the unit to power up and perform a self-test. The motor will not

run until this sequence is complete.

Refer to section 5.1 - CONTROLS for instructions and then electrically operate the unit. This will

verify that the unit works before it is installed.

If the unit is to be installed immediately, the battery fuse may be left in place. If the battery is fully

charged and the unit is to be stored, remove the fuse.

Any problems should be reported to the factory at (724) 864-4177. Please refer to the serial and

style numbers on the nameplate when making inquiry.

IB-AA10-025D

4.0 INSTALLATION

An installation, either new or replacement must begin with a completely installed and adjusted

overhead switch which is operating properly with a manual handle. The switch linkage, when

possible, should be adjusted so that the drive lever at the top of the vertical operating pipe goes

into toggle when the switch is closed. This provides a locking action to keep the switch closed

under short circuit conditions.

NOTE: Use discretion in lubricating the overhead switch. As the weather causes the lubricant to

deteriorate, operating friction increases thereby possibly reducing switch travel. Any significant

change in switch travel may affect auxiliary switch adjustment. See section 4.6 - 4.7.

4.1 DETERMINE LIMITS OF TRAVEL

Manually operate the overhead switch. Measure and record the approximate number of

degrees of vertical pipe rotation required to open and close the switch. You will need this

measurement when installing the decoupler in step 4.5.

4.2 DETERMINE AND PREPARE OPERATOR LOCATION

CLOSE THE SWITCH. If there is an existing operating device, remove it completely leaving the

vertical pipe in place. The only hardware needed from the original installation will be the vertical

pipe and the pipe ground strap. A new installation should have the vertical pipe in place but not

cut to length.

If this is a standard ground level installation, cut the bottom of the vertical pipe so that the end will

be 60" above ground level. If local practice requires mounting at a different height, cut the vertical

pipe to that length. Remember, the swing handle will be located

at the bottom end of the vertical pipe.

4.3 MOUNTING OPERATOR TO THE POLE

A. Refer to the attached drawings. Drill the two 11/16" (17mm)

diameter hanger bolt holes through the pole. The top hole

should be carefully drilled exactly even with the end of the

vertical pipe. The bottom hole should be 31"(787mm) down

from the top hole. Insert the top hanger bolt so the nut is on

the back side of the pole.

B. Slip the safety cover up high on the vertical pipe. Use tape

to temporarily hold it. Be sure the danger label is in front.

IB-AA10-025D

C. Uncouple and set aside the top half of the decoupler.

Remove the crossbolt, but

leave the bottom half of

the decoupler on the output shaft

Do not remove the

rubber bands from around the decoupler half. They

are there to provide the correct spacing between the

decoupler halves.

Lift the operator unit into place (the

top hole in the back channel is provided for hoisting).

As the unit is lifted into place, guide the lower end of

the vertical pipe over the output shaft and hang the

operator on the top hanger bolt using the keyhole

shaped mounting hole.

Insert the bottom hanger bolt from the back side of

the pole. The nut must go against the face of the

mounting channel. Tighten but do not overtighten the

hanger bolts. Install two lag bolts in the holes next to

the bottom hangar bolt. This will assure the unit does

not loosen as the pole shrinks with age.

Reinstall the crossbolt.

Note: A 1/8" gap is required between the end of the vertical pipe and the crossbolt. This is to

prevent the pipe from dragging on the bolt during an uncoupled motor operation.

4.4 ESTABLISH DIRECTION OF ROTATION

As received from the factory, the BT-D is wired according to customer specifications. Normally

it will be wired to run clockwise to open as viewed from above. If rotation as shipped is correct, go

to step 4.5. If opposite rotation is required, the change is done in two steps.

A. CHANGE THE PLUG-IN MOTOR CONNECTORS

Two small plug-in connectors will be found just below the motor. The male connectors are

labeled CW and CCW. One female end will have an arrow. Connect the end with the arrow

to the end labeled with the direction required to OPEN the switch.

B. RESET THE LIMIT SWITCH CAMS.

Changing the motor plug changes the limit switch orientation 180°. If the limit switches are not

changed, the decoupler will rotate to the rear of the cabinet and will damage the safety cover

if it is in place.

Fine adjustment of the limit cams is covered in steps 4.6 and 4.7. For now, they must be reset

to allow the unit to rotate the correct direction and stop close to the correct location.

Loosen the locking knob on the bottom of the auxiliary switch. (See the figure in step 4.6.) BE

CAREFUL TO ONLY MOVE ONE CAM AT A TIME. Turn the #2 (open position) cam (second

from the top) until the recess matches the recess of the #1 (top, closed position) cam. Rotate the

#1 cam until the recess matches the recess of the #4 (bottom) cam. Tighten the locking knob.

The #3 and #4 cams, which control the status signal to the RTU, will also need to be reset; but it

is best to leave this until final limit switch setting is done.

IB-AA10-025D

4.5 INSTALL THE DECOUPLER

A. With the overhead switch closed, loosely clamp

the top decoupler half to the vertical pipe. A

gap is required between the decoupler halves.

A pair of rubber bands are placed around the

bottom half serving as an installation spacer to

provide this gap. DO NOT remove the rubber

bands until the decoupler is completely in-

stalled. DO NOT couple the two halves at this

time. Using the total travel distance noted

before the old operator was removed, position

the top decoupler so that the travel stroke is

evenly divided on each side of the centerline.

Refer to sketch 1.

NOTE: If a fiberglass or very long steel vertical

pipe is in use, operator travel will have to be biased

as much as 20° towards the open position to allow

for “wind up” of the vertical pipe. Refer to sketch

2 and slip the decoupler toward the open position.

(Sketch #2 shows clockwise to open example.)

B. When the decoupler is located in its operating position, tighten the clamp bolts to 60 ft.-lbs.

Remove the rubber bands. Verify that a gap is present between the decoupler halves. Set

(pierce the pipe) ONE of the piercing screws. DO NOT TRY TO COUPLE THE TWO HALVES

AT THIS TIME. More information about the decoupler is found in sections 5.3 and 5.4,

however, no adjustment should be done at this time.

C. If not already done, install the battery fuse in the fuse block.

D. Put the selector switch in the “LOCAL” mode and electrically run the motor operator (still

uncoupled) to its “OPEN” position and back to “CLOSED.” Be sure the decoupler halves do

not interfere with each other and that the vertical pipe does not drag on the crossbolt causing

partial switch operation. If the decoupler halves are out of alignment more than 1/8" either way,

the auxiliary switch must be reset.

IB-AA10-025D

4.6 SET CLOSED POSITION LIMIT SWITCH

The auxiliary switch cams controlling the open and closed positions of the operator are set for

about 90° of rotation at the factory. The FINAL start and stop positions will have to be adjusted

to suit the individual overhead switch.

The sketch below identifies the cams used in the BT-D auxiliary switch to control operating travel.

All directions are as viewed from above. Adjustments are always made by turning the cams

in the OPPOSITE DIRECTION OF THE CORRECTION YOU NEED TO MAKE.

A. Loosen the auxiliary switch locking knob.

B. If the bottom decoupler half ran more than 1/8" past the top half (too far closed), the operating

stroke must be decreased by rotating the #1 cam toward the closed position.

C. If the bottom half stops short of the top half, the operating stroke must be increased by rotating

the #1 cam toward the open position.

D. Tighten the auxiliary switch locking knob and run the operator open and closed again with the

decoupler released. Recheck and repeat until the alignment is within 1/8".

E. Be cautious when moving the cam. Shaft rotation will change about the amount that the cam

is moved and is easy to over compensate. Take care not to move any cam but the one involved

in adjustment.

4.7 SET OPEN POSITION LIMIT SWITCH

Use the detachable swing handle (see sect. 5.3) to fully open the overhead switch. Replace

the handle in its hanger clip. Run the operator around to its open position. Just as with the closed

position, the operator will have to be adjusted until the decoupler halves align.

If the bottom decoupler half travels beyond the top half, decrease the operating stroke by

turning the #2 cam towards the open position. If the unit stops short of the top half, increase the

stroke by turning the cam toward the closed position. Operate the unit open and closed and adjust

until the decoupler halves align within 1/8".

IB-AA10-025D

4.8 ELECTRICALLY OPERATE OVERHEAD SWITCH

Couple the decoupler and electrically operate the switch open and closed. Carefully inspect

the switch to make sure that it is traveling through its full range of motion, and is closing completely

without excessive strain on the linkage. The installer should check the overhead switch stops and

contacts to determine if the overhead switch is fully closed. Inspection must be done at the level

of the switch by climbing the pole or using a bucket truck. Ground level observations are not

accurate. Make adjustments of the auxiliary switch until the switch has proper travel. Adjust the

overhead switch if necessary.

Verify the open gap. Open gaps are usually determined by utility operating standards, however

ANSI standard C37.32 - 1990 recommends the following open switch dimensions according to

switch voltage ratings. See chart below.

Example -- A switch with a 110 BIL rating should have an open gap of

approximately 10 inches but not less than 7 inches.

When the cams are set and the unit operates in a satisfactory manner, set the second piercing

screw on the decoupler pipe clamp.

4.9 SET AUXILIARY CAMS

Once the limit switch cams are set, the auxiliary cams controlling the RTU status input must be

set. The #3 cam (closed status) must match the #1 cam (closed limit switch). The #4 cam (open

status) must match the #2 cam (open limit switch). Once the auxiliary switch cams are set in

position to match the limit switches, turn them a little bit more in the SAME direction that the switch

was operating so they trip a little ahead of the limit switches.

4.10 INSTALL AC POWER AND OTHER CONNECTIONS

Install the RTU and radio/phone equipment, if not already done.

NOTE: RTU / Radio power sources for both 2.5 Amps @ 12 Volts and .75 Amps @ 24 Volts are

provided. For maximum efficiency use the 12 volt source whenever possible.

A removable access plate is provided in the bottom of the enclosure for entry of external wires.

Refer to section 5.7 for an explanation of AC-DC scheme Vs. DC scheme operation.

An adequate power supply must be provided for AC - DC scheme units. A minimum of #12

AWG wire should be used. See chart at below for requirements.

If the AC power supply is not adequate, change

from AC/DC scheme to DC scheme by unplug-

ging the 4 position Molex jumper connector found

in the center of the power module board mounted

on the back of the cabinet. See photo below. The

DC scheme requires a power source of at least 1

Amp for battery charging plus the radio and RTU

loads.

The battery fuse should be installed before con-

necting AC power. AC power connections are

made at the fuse block terminals. Be sure to

observe correct wiring terminal identification on

these connections as labeled. If a power supply

ground wire is present, connect it to the ground

lug below the fuse block.

Note: It is very important that the incoming power supply leads inside the cabinet

be kept as short and direct as possible. Magnetic pulses generated by high voltage

spikes, switching transients and power surges can and do affect the internal

electronic control components. When possible the supply leads should also be

twisted to minimize these magnetic fields.

A green LED light is located on the lower right corner of the power module board. It indicates that

AC voltage is present. Battery voltage should increase almost immediately when AC power is

connected. Use a voltmeter connected to the battery terminals to verify charger operation.

4.11 INSTALLATION OF GROUNDS (EARTH CONNECTIONS) and SURGE SUPPRESSION

Extensive testing and field study have determined that proper grounding of all components used

in an ADMO™™ installation is essential for proper operation, personnel safety and equipment

protection.

Electrical transients (surges) on utility systems can be caused by lightning, faults, switching lines,

spill gaps and by quick break whips that restrike. These surges can have serious side effects

ranging from reduced life expectancy of electronic components up to and including operation of

the motorized switch when not commanded to operate.

Take note that it is essential that all grounded components be solidly connected to a common

terminal on the pole ground (ground bus, downcomer, etc.). Any distance between these

connections can result in a significant rise in voltage potential during a surge, which in turn can

cause a heavy current flow in places where it is not wanted.

When installing grounds on the ADMO™™, follow your company standards and guidelines as to

wire gauge and connectors.

The following illustrations show do’s and don’ts regarding grounding practices. The arrowheads

on the conductors represent current flow during a surge.

A. Approved Practices.

1. All grounds MUST be connected to a single, common

connection on the pole ground. This common point can be

at any convenient location on the pole ground as long as all

individual grounds go DIRECTLY to it.

2. Whenever a ground strap from the operating rod is used,

it MUST GO DIRECTLY to the common point on the pole

ground. Be sure to leave enough slack in the ground strap

to allow full operating rod travel. Follow your company

guidelines about use of a ground strap on nonconductive or

insulated operating rods.

3. The ADMO™ ground must be connected from the factory

installed grounding lug to the common ground terminal on

the downcomer.

4. All communications wiring should be installed in properly

connected metal conduit. If metal conduit is not used, then

shielded twisted pair cable must be used. The shield must be

grounded to the cabinet at BOTH ends.

IB-AA10-025D

B. Poor Practices

The illustrations below show commonly used schemes which perform poorly. These should never

be used and if they are in place should be changed to one of the approved methods described.

C. Obsolete Practices

The schemes below were formerly specified by C/P Inc. Testing and field experience have shown

that these schemes do not perform as expected. These schemes should not be used for a new

installation.

IB-AA10-025D

C. Other Considerations.

1. An antenna surge arrestor should be used when installing a coaxial cable from a remote

antenna to the radio.

2. The ADMO™ 12 Volt DC power supply should`, whenever possible, be used to operate any

RTU/Radio mounted outside the ADMO™ cabinet. This power supply wire should also be installed

in metal conduit or use shielded twisted pair cable with shield grounded at BOTH ends. (Section

4.11A-4).

3. Incoming AC power supply wires should be sufficiently heavy to carry the ADMO™ operating

load. They should be twisted, and there should be only a very small loop in the wire inside the

cabinet. See section 4.10.

4. When an external RTU is mounted on a different pole from the ADMO™ and/or is controlling

more than one ADMO™, an optional 10 point surge suppressing terminal block is recommended.

Consult the factory for installation advice.

5. Every installation is subject to different conditions and has to operate according to a variety of

utility practices. We therefore strongly recommend that any apparent surge related damage to

electronic components or any unwanted operations be reported to the factory for surge analysis.
