Installation
1. Identify a location with enough space to accommodate the BRT 4/5 monitor.
Note: It is possible to install the monitor in the dashboard or on the top of the
dashboard with the stand.
2. The communication box is located inside the dashboard. You must select a location to
protect it with enough space to allow the installation of sensors and cabling.
CAUTION: Avoid installing the communication box near an extreme heat source.
Ideally, it should also be installed far from the radio antenna.
3. Secure the communication box inside the dashboard so that it does not move.

Installation Manual | V1.0.0 | 10
4. The communication box operates on a current of 12-24 VDC. Connect the power cable
(BRT 5137) to the fuse board. The red wire must be connected to a stable source with
a free fuse (minimum 5A). The black wire must be added to the board's common
neutral (or other neutral) for the scale monitor only. The other end of the cable should
be lead to the communication box in the "Power 12-24 VDC" indicated connector.
5. Connect the cable (BRT 5136) to the monitor and to the "Monitor" connector of the
communication box.

Tractor end
Four air hose options are available: BRT 580 (twisted), BRT 582 (straight), BRT 586 (twisted,
quick plug) or BRT 587 (straight, quick plug).
1. Identify the number of height valves on the tractor.
2. For each system controlled by a valve, an air line must lead to the TrackWeight
communication box.
3. Cut the air line as close as possible to the balloon to insert a BRT 5053 or BRT 5055
"T" fitting
1
(depends on the size of the air line tube).
Note: If the system is controlled by a single height valve and a dial already indicates
the air pressure, it is possible to connect to this pressure indicator in the cab.
4. Insert the cut air line and the ¼" BRT 5220 tube into the "T" fitting and lead this tube
to the front of the tractor in the cab.
5. Insert the BRT 5220 tube into the BRT 5792 fitting and route this tube to the BRT
560 air sensor, installed in the cab, to connect them together.
Note: To ensure a seal between fittings, use teflon.
Note: Make sure that the sensor is installed vertically, downwards, to prevent water
or condensation from accumulating in the sensor and damaging it.
6. Assemble BRT 5047 with BRT 5076 component as shown below.
7. Make a 1-in. diametre hole in the mounting wall.

For a group of 3 axles, insert the "T" on the middle one. For a group of 2 axles, insert the "T" on the
one at the back.

8. Insert the assembly made in Step 6 into the hole from the outside and from the side
of the BRT 5076 (the part on the side of the BRT 5047 part on the front side of the
truck).
9. Secure everything from the inside with the washer and nut from the BRT 5076
component.
10. Insert the BRT 5220 tube into the BRT 5047 component and route this tube to the
BRT 560 air sensor to connect them together.
11. Connect all BRT 560 air sensors to the communication box on the inputs. It is
important to identify the lines in order to properly configure the inputs in the
communication box afterwards.
12. On the outside, screw component BRT 5041 to part BRT 5076 and connect the right
(longest) side of the BRT 5502 twisted air hose.
13. On the other side of the BRT 5502 air hose (the side closest to the spirals), connect
the BRT 5556 service hand.

18. Make a 1-in. diameter hole in the mounting wall to insert the BRT 5565 service hand
with valve.
19. Insert the BRT 5051 fitting into the BRT 5565 valve and insert the BRT 5220 tube
into the fitting.
20. Attach valve BRT 5565 and service hand BRT 5556 together.
Note: The air line is closed when the handle of the BRT 5565 valve is perpendicular (as
shown in Step 18, right picture).

Installation on 6 - 10 - 12-wheel truck configuration
1. Identify the number of height valves on the truck.
2. For each system controlled by a valve, an air line must lead to the TrackWeight

Note: If the system is controlled by a single height valve and a dial already indicates
the air pressure, it is possible to connect to this pressure indicator in the cab.
4. Insert the cut air line and ¼" BRT 5220 tube into the "T" fitting and lead this tube to
the front of the truck.
5. Insert the BRT 5220 tube into the BRT 5792 fitting to connect it to the BRT 560 air
sensor, installed in the cab, to then connect the same sensor to the communication
box. Identify the lines in order to properly configure the inputs in the communication
box afterwards.
Note: Make sure that the sensor is installed vertically, downwards, to prevent water
or condensation from accumulating in the sensor and damaging it.

Installation
1. Determine the correct location for sensor installation.
Note: Make sure that the RT sensor does not interfere with fixed or moving parts of
the vehicle.
›For the front axle(s): Ideally in the center of the axle. However, be sure to check
the clearance of the truck and have a good clearance (with the protective
cover) so that the sensor does not catch on the oil pan or any other part of the
truck.
›For rear axles: Place the sensors in opposite positions, ideally centered
between the "bushing" and the wheel. Make sure there is at least 10 cm
clearance between the sensor and the wheel. The sensor on the driver's side
must be on the back of the axle and the one on the passenger side must be on
the front of the rear axle group.
2. Prepare the "beam" structure for welding by removing any paint, rust and/or other
potential contaminants.

Installation Manual | V1.0.0 | 19
3. Place the fixed and adjustment block at the center of the width of the chosen
location on the structure (axis or "beam"). The blocks should be placed face-to-face
within 50 ± 2 mm of each other.
Note: If you have the BRT9081 installation assistance tool, you only need to make
sure you find the center of the beam width and check the clearance.
4. Use pliers to hold the blocks in place before welding.
5. Preheat around blocks up to 65 ° C.
6. "Stop" each outside corner of the two blocks to the structure. See Figure p. 20.
IMPORTANT: The use of the welding rod or 309L-16 wire, rustproofing, or 7018,
steel, is mandatory. See Appendix 2 for rustproofing weld procedures

7. Make a weld in 3 passes on each side of the two blocks. The weld must exceed the
blocks by at least 15 mm.
8. Vertically weld 2 ¼-20 x ½" steel bolts (or rustproofing, depending on option
purchased) at the position shown in the image below.
9. Hide threads (stationary block and bolts) and apply rustproof black paint while axle
and blocks are still hot.
