General Information
2.
The Condux Fiber Optic Cable Puller is a hydraulic pulling machine designed for fiber optic
cable placement. It offers bi-directional pulling and load-sensing capabilities. The system
uses a hydraulic motor and capstan with an electronic tension control system.
The tension control system uses an electronic load cell to measure the actual torque at
the puller’s motor. Combining this torque value with the capstan’s diameter ensures accu-
rate tension monitoring. The system’s design gives the operator complete control over the
equipment. It can be set to a maximum tension limit that will stop the puller and give both
audible and visual alarms if the tension limit is exceeded during the pull.
A digital chart recorder continuously records the pulling tensions during operation. The
power pack or the vehicle’s 12 Volt DC power point energizes the electronic tension
control system.
The puller comes standard with a variable speed foot control and hoses to the puller motor,
an adjustable flow control valve for adjusting maximum pulling speed, and a manually
adjustable pressure relief valve for adjusting the maximum pressure supplied to the
hydraulic motor.

Set up the Puller
This manual contains setup and operating instructions for the Condux Fiber Optic Cable
Puller with electronic control box, if equipped. Where operations differ for the other
available packages, the instructions specify those differences.
A. MOUNT THE PULLER
1. The Fiber Optic Cable Puller has a 2
1
⁄ 2 x 2
1
⁄ 2 inch (64 x 64 mm) square mounting post.
A female receiver, such as the receivers listed in appendix 13.F and 13.G, is
recommended. Use grade 5 or grade 8 capscrews to attach these mounts. Materials
used for constructing your own mount should have a minimum wall thickness of
1
⁄ 4 inch (6.25 mm). All welds should be continuous, and gussets should be used
where possible.
!CAUTION: Lift the Fiber Optic Cable Puller only with proper equipment or
sufficient manpower. Improper lifting techniques may result in personal injury
or property damage.
B. CONNECT THE HYDRAULIC SYSTEMS
The Fiber Optic Cable Puller’s hydraulic system uses quick-connect couplings. Keep all
connections clean to avoid contamination and possible system failure. Follow these steps
to connect the hydraulic components:
1. Connect the hydraulic supply hoses to the foot control valve assembly. Ensure the
pressure hose from the power source goes to the inlet of the foot control valve
(labeled PRESSURE on the foot control valve assembly, figure 1).
2. Connect the hoses from the foot control valve assembly to the puller (figure 2). The
supply hose assembly has four identical male couplings and can be attached between
the puller and foot control valve assembly in any orientation.
!NOTE: Switching the quick-connect couplings on one end of hose assembly
between the puller and the foot control valve assembly will reverse the direction of
capstan rotation.
3. Start the hydraulic power source and check all connections for leaks with a piece of
cardboard. Run the puller in both directions to ensure proper operation.

!WARNING: Escaping fluids under pressure can penetrate the skin and cause seri-
ous personal injury. Observe the following precautions to avoid hydraulic hazards:
• Tighten all connections before applying pressure. Relieve pressure before
connecting or disconnecting hoses.
• Check for leaks with a piece of cardboard. Do not use hands!
• Do not exceed working pressure of hydraulic hoses. Visually inspect hoses
regularly and replace if damaged.
5. Run the puller for approximately 1 minute to remove any trapped air and then stop the
hydraulic power source.
!CAUTION: Use a minimum 10 micron nominal filter for proper filtration of the
hydraulic system. Equipment failure could result from improper filtration.
C. POSITION THE FOOT CONTROL VALVE ASSEMBLY
The foot control valve assembly controls the speed and direction of rotation of the cap-
stan. The further the foot pedal is pushed down, the faster the puller turns. To temporarily
reverse the capstan, the foot pedal can be lifted up.
!NOTE: Cable must be pulled only while pushing down on the foot pedal. To pull
cable with the capstan rotating the opposite direction, reverse the quick-connect couplings
of the hydraulic hoses on the puller (see previous section).
1. The foot control valve assembly is fitted with an adjustable speed control stop. The
speed control stop relieves operator foot fatigue by limiting the downward travel of the
foot pedal. Do not force the pedal if it does not move. Adjust the speed control knob
counterclockwise to increase speed, clockwise to decrease speed. The operator should
now feel the pedal move freely.
2. Position the foot control valve at least 3 to 4 feet (0.9 to 1.2 m) from the capstan’s
feed-off side (figure 3). Position the foot control in the best possible location for
safety and proper operation. Multiple operators may be required for safety or
operational requirements.
3. The manually adjustable pressure relief valve allows a secondary method of controlling
the maximum pulling tension. The relief valve is factory set to release the hydraulic
pressure at approximately 700 pounds (3113 N) of pulling tension while using the
Condux 30 inch (762 mm) diameter capstan. If required, adjust the relief valve to a
20°

different load setting. See section 11.B for details. For proper operation, the relief valve
must be set at a tension limit greater than the electronic tension limit.
D. ATTACH THE CAPSTAN
1. Attach the 30 inch (762 mm) diameter capstan to the puller’s shaft (figure 4) by aligning
the capstan’s slots with the shaft’s pins. Push the capstan onto the shaft until it stops,
then rotate clockwise until it stops. Pull outward to lock the capstan into position. Make
sure the shaft locking pins are visible through the holes in the capstan hub.
!NOTE: If using a capstan with a diameter other than 30 inches (762 mm), the hydraulic
relief valve must be recalibrated (section 11).
Set Up the Electronic Control
System
If the puller is not equipped with the electronic tension control system, go to section 7.
A. SWITCH CONFIGURATION

B. CONNECT THE ELECTRONICS
!DANGER: The electronic control box is an electrical device. Electric shock
hazards exist that could result in severe personal injury or death. Observe the
following precautions:
• Do not expose electronic control box to water.
• Do not remove cover of electronic control box (no user-serviceable parts inside).
Refer servicing to qualified personnel.
• The electronic control box power switch should be in the off position before
connecting or disconnecting any cords.
1. Connect the male end of the 5-pin sensing cord to the female connector on the
Electronic Control Box labeled “LOAD CELL”. (see Figure 6) Connect the female end
of the cord to the male receptacle located near the load cell. (See Figure 7). Before
making these connections, ensure the receptacles are free of dirt and moisture. Do not
modify this cord’s length.
Tighten the connector collars over the threaded portion of the receptacles. This prevents
the cord from coming loose during operation. This cord is necessary to measure the ten-
sions sensed by the load cell.
2. Connect the male end of the 3-pin footswitch control cord to the female connector on the
Electronic Control Box labeled “FOOTSWITCH” (see Figure 8). Connect the female end of the
control cord to the male receptacle located on the foot control valve assembly (see Figure 9).
NOTE: If the connector on the foot switch is 2-pin, use the patch cord (08675926) included in
the upgrade kit (08675920) to convert to the required connection. Before making these connec-
tions, ensure the receptacles are free of dirt and moisture. Do not modify this cord’s length.
Tighten the connector collars over the threaded portion of the receptacles. This prevents
the cord from coming loose during operation. This cord is necessary to measure the ten-
sions sensed by the load cell.

3. The 7/8” 2-pin connector on the front
panel of the electronic control box sup-
plies electrical power to the electronic
control box. (see Figure 10) This power
can come from the power pack, a
vehicles power point, or a lighter socket.
The electronic control box requires 12
Volt DC power for proper operation.
4. Connect the power cord to the 2-pin con-
nector labeled “POWER”. Before making
these connections, ensure the receptacle
is free of dirt and moisture. Tighten the
connector collar over the threaded por-
tion of the receptacle. This will prevent
the cord from coming loose during opera-
tion. Connect the other end of the power
cord to a 12 Volt DC power source.
C. SETTING UP THE ELECTRONIC CONTROL BOX
The Condux Fiber Optic Tensiometer has been designed to give the operator continuous
tension information and automatic shut-off control during a pull. The Electronic Control
Box features an LED Display, Digital Graph Display, 256MB Flash Card, and a 3 cap-
stan selection switch. A programmable overload set point with both visual and audible
alarms is designed to disengage the cable puller should an overload occur. Navigator
software is provided so pulling information can be downloaded onto any computer run-
ning Windows 2000® or XP®.
!DANGER: The Main Power switch supplies power to the indicator and chart
recorder. When a power supply is connected to the electronic control box, portions
of it are energized. Follow all electrical equipment precautions.
!NOTE: Always disconnect the power cord when the electronic control box is not in use.
When the power cord is connected to the electronic control box, it energizes portions of the
control box. If the power cord is left attached when the control box is not in use, it will drain
the power supply.
1. Turn the power switch on the Electronic Control Box to the “ON” position (See Figure 5).
Be sure that the sensor cords are properly connected before turning on power.
2. Select the capstan size. Turn the capstan selection switch so the appropriate chan-
nel is lit on the Meter. In order to get accurate results, the correct capstan size must be
selected. The electronic control box is programmed to accurately return pull tension for
Condux 12”, 30”, and 42” fiber optic capstans.
3. Set the cable Tension Limit. Press the “Prog” Button and ▼ button simultaneously.
(See Figure 5) SP-1 will appear on the on the LED Screen. The screen will alternate
between SP-1 and the current tension limit. Press the ▲ and▼ buttons to increase or
decrease the tension limit. Once the desired tension limit is set, press “Prog” to save the
set point.
4. Zero the display. Press the “Prog” button.
5. Alarms: When Tension Limiter switch is in the “OFF” position the audio alarm will sound
and the light will come on when the tension limit is reached. When the Tension Limiter
switch is in the “ON” position the puller will also stop pulling when the tension limit is
reached (See Figure 5)
!CAUTION: Damage to cable may result from excessive pulling forces. Use
precautions to safeguard against overload conditions.

Puller Operating Instructions
a. Slowly press the foot control pedal. Remove any slack or excess pull line before
increasing the puller’s speed. Attend the line coming off the capstan to avoid any
tangles, and keep some tension on the line so that the capstan grips the pull line.
Never wrap the line around your hand, arm, foot, or leg, and always be prepared to
release the line. Stand at least 3 to 4 feet (0.9 to 1.2 m) away and at a 20 degree angle
from the capstan. Wear gloves to avoid rope burns and abrasions.
!NOTE: To avoid damage to the fiber optic cable, always start the pull slowly, and
increase speed as the puller and cable stabilize.
!CAUTION: Stand to side of pull line to prevent injury in case it breaks. Always wear
protective equipment: hard hat, safety glasses, safety shoes, and work gloves.
!WARNING: Stay clear of the rotating capstan. Severe personal injury or death
could result from entanglement with it or the pull line. Follow these safety precau-
tions:
• Do not wrap the pull line around a hand, arm, foot, or leg.
• Always be ready to release the pull line.
b. When the TENSION LIMIT CONTROL is ON, the puller will stop pulling if the cable
tension exceeds the programmed limit of the electronic control box. Release the foot
pedal and the cable or pull-line tension will slowly release.
Slowly reverse the puller to release cable or pull-line tension by lifting up on the foot
pedal. Many pull lines build up tension from stretching. Never approach or service a
pull line under tension. Always release tension before proceeding.
c. When the electronically programmed tension overload limit is set higher than the
adjustable relief valve, the puller will stop when the relief valve setting is reached.
Increase the relief valve setting by turning the manifold knob clockwise. To decrease
the setting, turn the valve counterclockwise. See section 11.B for details on adjusting the
relief valve manifold.
d. If the pulling operation exceeds the electronic tension limit or relief valve setting, correct
the cause for high tension.

Puller Calibration
When using the electronic control system, the Condux Fiber Optic Cable Puller does not
need to be calibrated on a regular basis; however, the calibration should be checked peri-
odically (at least yearly) to ensure that the calibration has not changed. If the calibration
procedures specified below are not possible at the operator’s location, we recommend
returning the unit to Condux International for calibration by the factory. See section 15 for
details on returning the puller to Condux International for calibration.
A. VERIFY THE PULLER’S CALIBRATION SETTINGS
1. Set up the puller as if cable were to be pulled, including installation of the capstan (fig-
ure 21).
2. Place a pull line around the capstan. The pull strength of the pull line must exceed the
2,000 pound maximum capacity of the Fiber Optic Cable Puller.
3.
Attach the pull line to a load indicator such as a Dillion dynamometer (section 14).
4. Set the electronic control box tension limit according to the load rating on the capstan.
5. Slowly apply pressure to the puller to tighten the pull line. Continue to pull until the relief
valve opens. The value shown on the dynamometer will be the force at which the pres-
sure relief valve is set for this hydraulic fluid temperature (see next page).
6. Release pressure to the puller.
7. Set the electronic control box tension limit to the desired tension to be verified.
8. Slowly apply pressure to the puller to tighten the pull line. Continue to pull until the elec-
tronic control system stops the puller and the alarm sounds. The value shown on the
dynamometer should match the tension limit set on the electronic control box.
B. HYDRAULIC PRESSURE RELIEF VALVE CALIBRATION
The hydraulic pressure relief valve on the Fiber Optic Cable Puller is calibrated to the fol-
lowing loads.
• Relief Valve: 1,783 lbs. (7,930 N) line tension on the 12" (305 mm) diameter capstan
700 lbs. (3,113 N) line tension on the 30" (762 mm) diameter capstan
428 lbs. (1,903 N) line tension on the 42" (1,067 mm) diameter capstan
If a different load is required, the relief valve can be adjusted with the following procedure.
Do not execute this procedure to verify the calibration (see previous section).

control system or other load limiting means. Damage to the cable being installed
may result.
1. Set up the puller as if cable were to be pulled, including installation of the capstan (fig-
ure 21).
2. Place a pull line around the capstan. The pull strength of the pull line must exceed the
2,000 pound maximum capacity of the Fiber Optic Cable Puller.
3. Attach the pull line to a load indicator such as a Dillion dynamometer (section 14).
4. Release the lock nut on the relief valve (figure 22). Turn the relief valve stem counter-
clockwise to adjust the valve down to zero pressure.
5. Slowly apply pressure to the puller to tighten the pull line. Continue to pull until the relief
valve opens. The value shown on the dynamometer must be below the desired maxi-
mum load.
6. Release pressure to the puller. Turn the relief valve stem clockwise to increase the pres-
sure setting (figure 22).
7. Slowly apply pressure to the puller to tighten the pull line. Continue to pull until the relief
valve opens. The value shown on the dynamometer is the maximum load that the puller
can pull. Repeat steps 6 and 7 until the desired maximum load is obtained.
8. When the desired maximum load is obtained, tighten the lock nut on the relief valve.
9. Verify the relief valve setting by slowly applying pressure until the relief valve opens.
Check the value on the dynamometer and adjust the relief valve if necessary.
!CAUTION: Use the relief valve pressure only as a backup to the electronic tension
control system or other load limiting means. Damage to the cable being installed
may result.
!NOTE: Measuring the hydraulic pressure to the puller is not an accurate means for deter-
mining the pulling tensions. Component age and oil temperature affect hydraulic motor
efficiency and torque output. The following chart shows the different approximate pulling
tensions at different oil temperatures with a 30 inch (762 mm) diameter Condux capstan.
Use this chart as a comparative reference only and do not consider it to be the actu-
al pulling tensions.

C. ELECTRONIC TENSION CONTROL SYSTEM CALIBRATION
The electronic tension control system automatically calibrates itself to the 12”, 30” and 42”
Condux capstans simply by turning the Capstan Selection Switch. To verify calibration
see section 11.A.
!NOTE: If the puller calibration is in question, contact the factory for calibration information
at 1-800-533-2077.

Troubleshooting Guide
A. PULLER
12. SOLUTION:
•Reverse the connections on one end of
the hose assembly between the foot con-
trol valve assembly and the puller (see
section 5.B.2)
.
• The adjustable flow control knob on foot
control could be limiting movement. Turn
flow control knob counterclockwise until
full movement is achieved (see section
5.C.1).
• Check that the area under the foot control
pedal is clean and free of all obstructions.
• Check adjustable pressure relief valve
setting to ensure that it is not opening
prematurely (see section 11.B).
• Check the hydraulic power source that the
hydraulic power provided to the puller is
the required 2000 to 2500 psi (137-172
bar) of pressure and 6 to 10 gpm (22.7-
37.9 lpm) of flow.
• Check system for hydraulic leaks.
• Puller is not properly aligned with the pull
line. The pull line must be placed around
the capstan at a slight angle to the edge of
the capstan (see section 7.A).
• The posts on the shaft must line up with
the grooves on the capstan (see section
5.D).
• Apply an anti-seize compound to the ID
of the capstan and the OD of the puller
shaft.
• Hydraulic pressure is remaining in the
hydraulic lines. Carefully unscrew one of
the quick-connect couplings to relieve the
internal pressure. Before disconnecting
the hoses, be sure to cycle the foot
control valve with the power supply off to
relieve any internal pressures.
• Contamination has gotten into the cou-
plings. Visually inspect couplings; clean
and remove any contamination. Use the
supplied dust caps.
PROBLEM:
Capstan does not rotate in the required
direction when the foot pedal is depressed.
Foot control pedal will not depress fully.
Puller is not achieving maximum pulling
force or speed.
Pull line will not stay on the capstan.
Capstan will not go onto the puller shaft.
Hydraulic quick-connect couplings will not
go together.
