General information

The Trigg AIR is a unique handheld device for installing fiber optic directly into a pipe. The Trigg AIR consist of an air block with max air pressure of 16 bar and duct clamps for 5,0- and 7,0-mm ducts. The unit’s 12 V battery operated drive wheel will combined with air install fibers from 0,5-3,0 mm into an airtight duct, at speeds of 0 to 0-150 m/min. With the build in digital LCD display, displaying speed and distances and the manometer you always have full control of the process. The start button can be locked in the speed you like for “automatic drive”. Reverse function helps if you need to pull out a fibre.

The Trigg AIR is operated without tools. The built-in adjustable clamp  force greatly optimizes the pulling stress on the fiber. The unit have an adjustable clutch for fibre security. This fiber protection system prevent damages on the fiber if the fiber hits an obstruction.

The Trigg AIR is supplied in hard side case including the Trigg AIR, box for seals, 2 pcs battery and charger. As option for the Trigg AIR you can get a tripod and reel arm kit for pre terminated fibre.

These operating instructions contain a full description of the TriggAIR, which have been designed for the purpose of feeding fiber through a duct. The duct must have previously been installed underground or overhead to receive the fiber cable and must be of enough length on exit to be received by the machine. The duct must be of material with enough compression strength for it to be adequately sealed in the duct clamps of the machine. The duct must be airtight up to a pressure of 16 bar. Duct sizes range from 5 mm-7 mm, while fiber optic fiber(s) range from 0,5 mm-3 mm.

The Trigg AIR consists of an air block/duct clamp that is made in two halves that clamp together around the duct. The duct clamp holds a seal that the fiber optic fibre is feed through before entering the duct. The duct clamp can be used for both 5,0- and 7,0-mm ducts. Fiber seals can be interchanged to accommodate different fibre sizes. The duct is mechanically clamped between the duct clamps at the exit of the duct clamp, preventing movement in any direction. Seal is placed around the fibre when clamped.

The fibre cable is fed through the duct by a combined pulling/pushing force. The pulling force is achieved when pressurized air is fed into the air block and forced into the duct, generating drag on the fibre from the airflow passing over it. The pushing force is created by engaging the drive wheel system. As the drive wheel feeds the fibre cable into the duct, drag force is created by the airflow. The fibre cable flies in the duct, minimizing any resistance to being pushed in by the drive wheel.

The use of the Trigg AIR for operations other than those described in this manual are considered dangerous and are discouraged. Use of this machine for work other then what is intended, relieves the manufacturer from any responsibility, civil or penal. The manufacturer’s responsibility ceases, and the warranty is voided when one of the following occurs:

Observe all safety information on this page and note specific safety requirements as explained by procedures called out in this manual. Failure to follow these instructions could result in serious personal injury, property damage or death.

A. Work area safety

1. Wear personal protective equipment: hard hat, safety glasses, safety shoes, and light leather work gloves (OSHA approved or personal protective equipment directive 89/686/EEC compliant).
2. Wear close fitting clothing to avoid clothing getting trapped in belt drive.
3. Keep long hair tucked back and refrain from wearing any jewlery.
4. The safe operation of this equipment requires that the operators be on stable footing.
5. Stay clear of fibers or lines under tension.
6. Stay clear of pressurized line and conduit.
7. Use the blower only for its intended purpose.
8. Do not place fiber reel too close to unit. Place the reel far enough away from the unit to ensure proper control.
9. Keep hands away from belt drive while blower is in operation

B. Electrical devices

The motor, controller, and digital display are electrical devices. Electrical shock hazards exist that could result in severe personal injury or death. Observe the following precautions to avoid electrical hazards:

1. Do not operate in or near water. This includes setting the unit on a wet surface or exposing to rain.
2. Do not operate when there is lightening or extreme weather. An earth stake driven into the ground as added protection is recommended if there is any chance of extreme weather developing.
3. Do not remove the digital display cover. There are no user serviceable parts inside.
4. The drive should be switched off before connecting or disconnecting any cords.

Set up the Trigg AIR

This manual contains setup and operating instructions for the TriggAir.

Do not connect power supply until setup is complete.

• A. Determine fiber size

• Determine fiber size to be installed.

• B. Select cable seal

• Choose the correct cable seal matching the cable size.

• C. Install cable seal and fiber in track

• Install the appropriate cable seal on the cable. Once the cable seal is positioned properly on the fiber you can install the fiber cable in the wheel drive, see E.

• D. Install duct

• Ensure there is adequate length of duct available to avoid unnecessary strain on the duct.

• Place fibre cable into duct, place fibre cable and seal into the duct clamp.

• Once the duct is in place, secure the configuration by closing the top half of the duct clamp and pressing firmly together. Close duct clamp cover and hand tighten the knob to secure.

• E. Install fiber cable in the wheel drive and tighten

• Feed the cable in the wheel drive.

• Tighten adjustable clamp force wheel using the screw knob to ensure even pressure on the fibre cable. Do not over tighten!

• F. Adjust clutch for fibre security

• Adjust if needed, tighten it by turning the knob right and loosing it by turning left.

• G. Connect battery to blowing unit

• H. Connect air compressor
  NOTE: Ensure the air control valve is off before connecting the air hose.

• Attach the air compressor hose to the air compressor if necessary.

• Then connect the compressor hose to the blower unit. The unit uses a standard quick connect air compressor coupling (always use water separator on the compressor).

To avoid creating a trip hazard always route air hose out of the way and secured to a stable object.

The fiber pan/reel should be placed axially perpendicular to the length of micro duct and typically 6 ft (2 m) or more from the Trigg AIR. The Trigg AIR must be positioned in line between the fiber to be installed and the micro duct. The fiber should not enter the Trigg AIR at an angle of more than 10 degrees from the intended axis.

Crash test

Fiber Crash Testing is a very quick and easy step to be completed before attempting the installation of fiber cable with the Trigg AIR. This test is necessary to set the pushing force control of the motor below the point that the Trigg AIR may cause fibre damage as a result of over pushing or encountering an obstruction in the sub-duct system.

Every fiber has different pushing values and these values vary depending on duct I.D.

Always wear protective equipment: hard hat, safety glasses, safety shoes and work gloves.

IMPORTANT
For the Crash Test to work properly, use the same size fiber and pipe that will be used for the job. Jetting cannot be responsible for any fiber damages.

Crash Test: For all types of fibers > 0,5 mm diameter 

1. Insert the fiber and seal inside the duct as it would be for the actual installation.
2. Install a 1 to 2 m test length of duct into the TriggAIR clamp.
3. Block the end of the test length of duct.
4. Tighten the wheel pressure on to the fibre with the wheel drive engaged in the forward direction until the fibre starts to install.
5. Ram the fiber into the blocked end of the duct.
6. Fibre cable should stop before the fiber folds over/are damaged. If the fibre cable do not stop go to step 7.
7. Reduce the adjustable clutch for fibre security.
8. Repeat step 6-8 until the fiber folds. This is your push force slip limit.
9. Loosen up the wheel on the fiber a quarter turn and perform test once more to confirm no fold over has occurred. KEEP THIS SETTING APPLIED TO THE FIBER FOR ACTUAL INSTALLATION!
10. Swap out test length of pipe with actual installation duct and proceed to operating the TriggAIR.

Blower operations

1. Verify adjustable push force
   Verify adjustable push force is set to the established crash test value  and the speed is at minimum.

2. Engage wheel drive
   The wheel drive can be operated forward and backward. For installation, engage the wheel drive in forward by pressing the button. Install the fiber into the duct using push only until the installation has slowed.

3. Engage air
   Slowly open the air control valve to allow air flow to the air block. Do not apply maximum air pressure and flow at initial air engagement. Do not open the air supply before adequate fiber has been pushed in (approx. >100M).

MPORTANT Do not exceed 16 bars when operating the unit.

Forced air creates flying debris. Always wear personal protective equipment.
Motor is not covered by warranty if motor is overheated. When exceeding maximum pushing force (clutch fully engaged), let the motor cool down between the cycles.

4. Adjust speed
   Use the button to adjust the drive speed to ensure smooth installation and match the amount of air pressure being used so that the forces are working together, not against one another.

5. Install fiber cable
   It may be helpful to guide/apply back tension to the fibre using your hand at the fibre entrance of the machine to maintain control over the fibre.

6. Switch of the machine to prevent battery damage
   When the battery is emptied, the engine stops. Still the display lights up. It is important not to forget to switch off the machine or you will ruin the battery.

Troubleshooting guide

Fiber becomes jammed in the duc

1. Inform the people at the other end of the pipe that a problem has been experienced and the operator is going to shut down the system.
2. Shut off the air supply with the air control valve, allowing the air pressure to be depressurized from the duct and the duct clamp air block.
3. Using the counter or the measurement on the fiber cable, determine where the blockage might be located.
4. Notify supervisor about problem and determine a solution accordingly

Wheels does not pull the fiber

1. Assist the reel by pushing the cable of the reel.
2. Adjust the clamping force.

Hard to restart after stop

1. Put more/less air to the system.
2. The wheel can be restarted after the air pressure has increased and stabilized

Wheel feed does not start

1. Battery is low, check battery indicator
