2. Working under vehicles To install the Modul Connect On-board Vehicle Weighing System it is necessary to work from the underside of the vehicle.

A vehicle lift, such as a 2 post or 4 post ramp, is recommended for installation. Lifting plant and equipment can cause accidents if they are used unsafely or are poorly maintained. Vehicles falling/rolling off incorrectly positioned jacks or stands, particularly where they are not chocked, are one of the main causes of fatal accidents. Working beneath a vehicle for various tasks is often required, but because these tasks are so common people get used to working under potentially lethal weights. Jacks and axle stands:

• Always use the right equipment for the job. • Make sure all operators are trained, competent and capable. • Don't take short cuts or use inappropriate equipment to lift heavy items. • Use equipment correctly. • Make sure there are safe working procedures in place when moving heavy loads, particularly

when they are raised. • Use the correct pins for axle stands - screwdrivers, nails and bolts are not acceptable. • Use stands on a hard, level surface e.g. concrete and avoid lifting on sloping ground. • If the area is unsuitable then move the vehicle to a safer place before any attempt is made to

lift it. • Securely chock wheels remaining on the ground. • Make sure that all lifting points for jacks and stands are correct for that vehicle - consult the

vehicle manufacturer's handbook for guidance. • Do not exceed the rated capacity (safe working load) of any lifting equipment. • Ensure that vehicles are always properly supported - do not rely on jacks alone.

Ramps and lifts:

• Make sure lifting equipment is correctly installed. • Make sure all operators are trained, competent and capable. • Maintain lifting equipment and train operators to use it correctly. • Vehicle lifts need to be kept in good order. Follow the manufacturer's instructions and

replace consumable items, such as lifting pads, before they become unsafe. • Check equipment regularly and get it inspected.

Additionally, for two post lifts: • Make sure employees evenly balance the lift for different types of vehicle and where any

major components have been removed - knowing where the centre of gravity is important to prevent vehicles falling from a lift.

• Ensure that the arm locks are fully engaged and secure and that all the lifting pads are positioned correctly before raising the vehicle to full height.

4. Preparing for installation WARNING: All wiring should be done by a certified technician or electrician to ensure adherence to the applicable electrical safety wiring regulations and installation codes. Failure to follow these instructions can damage the box and could also result in personal injury or loss of life. To ensure a reliable and properly functioning system, particular importance should be paid to the following: • Transducer installation. A suitable location for the transducer should be carefully identified and that location should then be prepared for the transducer to be attached. Please refer to the “How to install a steel axle transducer” section on page 11. • Transducer orientation. Axle transducers must be mounted to the vehicle in the correct orientation. Please refer to the “How to install a steel axle transducer” on page 11. • Accurate recording of sensor serial numbers in their sensor positions. It is recommended that you use the system configuration table to record this information and refer to it when you are configuring the system. Please refer to the “Weighing system connection table” on page 27. • Accurate reference box orientation. The cables from the reference box must exit to the rear of the vehicle. Please see page page 7-8. WARNING: DO NOT CUT, SHORTERN OR MODIFY ANY YELLOW CABLE. This will affect the weighing system’s performance and give inaccurate readings. Before starting any installation, ensure you have the following equipment and tools:

• 1x 24000-03 Modul-Connect main box (and a mobile phone or tablet with the Modul-Connect application installed)

• 1x 24200-03 Molex terminal housing • 4x vehicle weigh pads or some way of weighing the front and rear axles of the vehicle. • A ramp to lift the vehicle for working underneath. • Suitable weight so the van can be loaded to its maximum payload (in the load area and cab

area). • The tools listed below:

Screwdriver set Hex driver set Torx driver set Socket set Multimeter Side cutters Drill Drill bit set G-Clamp/s Calculator Hot air gun

When installing to vehicles that have covered a few miles, additional items required could be: Scotchbrite pad/s Brake cleaner

5. Understanding the main features

• Choose an appropriate mounting location. IMPORTANT: The Reference box must be mounted on a flat surface under the vehicle. The orientation of the Reference box is very important; the cables from the Reference box must exit to the rear of the vehicle. The Reference box will:

• Remotely store the weighing data entered into the system. • Measure the inclination of the vehicle in any plain.

The 4x axle transducers are mounted on the suspension components. There transducers measure the angle of the suspension component and are set at no load (zero weight) and maximum load (span weight).

The Modul Connect On-board Vehicle Weighing System then calculates the load, considering the inclination of the vehicle and displays this through the Modul Connect system.

8

6. Installing the reference box Safely raise and support the vehicle to a convenient working height. Please refer to the safety information found in the “Working under vehicles” section on page 4. Select an appropriate mounting location for the Reference box under the vehicle. The best location is to the middle or the rear of the vehicle. The box can be mounted in any orientation, but the direction is fixed. IMPORTANT: The cables from the Reference box must edit to the rear of the vehicle.

The ‘Top’ face of the Reference box is denoted by the identification label showing.

Facing downwards Facing upwards Facing right Facing left

• Make sure that the Reference box cannot be damaged by any moving parts on the vehicle. • Ensure that the cables from each sensor can reach the reference box box. • Ensure that the cables can be routed from each transducer without risk of damage from any

moving parts on the vehicle. • Ensure that the 7 meter ECU Interface Cable can be routed without risk of damage from any

moving parts from the reference box to the Modul Connect main box. • Make a note of the orientation of the top face of the reference box, e.g. facing up, down, left

or right side of the vehicle. In the example shown above, the junction box is facing down. Note this in the “Weighing System Connection Table” on page 27.

• Ensure that adequate access can be made for plug and cable entry. • Mount directly to a flat metal surface. • If possible, use existing holes on the chassis to mount the reference box. • If required, drill the 2 mounting holes and place the box in position and fasten the box to the

mounting surface.

9

• The box can be mounted with 2x M6 bolts, washers and nuts (tightening torque 12-13 Nm) or a similar secure fixing (not supplied).

• Use a mounting template to mark the positions of the mounting screws. • Mark the DEUTSCH Connector: on each of the transducer sensors with its position number

on the vehicle, you will need this when connecting to the reference box.

Picture showing reference box mounting. The reference box is mounted facing downwards.

7. Installing the axle transducer sensors The transducer sensors are to be mounted on the steel components of the vehicle’s suspension system. This includes:

• Strut type suspension • Single axle leaf springs

Sensor installation positions

• The first step to transducer sensor installation is to select the appropriate position to install each sensor on the vehicle.

• Each transducer sensor has a serial number. Make a note of the serial number of each transducer sensor which you install, its position number and where it is installed on the vehicle.

• Use the Weighing system connection table to record this information and refer to it when you are configuring the system. You will find the table on page 24.

Axle transducer sensor mounted on a front strut Select a position to install the transducer sensor on the lower wish bone of the front strut where:

• The transducer sensor is perpendicular to the orientation of the chassis with the cable running away from the wheel.

• The transducer sensor is not at risk of damage from any part on the vehicle throughout the full range of movement of the strut.

• The transducer sensor cable can be routed to the reference box without risk of damage from any moving parts and allowing for the full range of movement of the transducer on the strut.

When mounting the transducer sensor, ensure it is in the correct orientation, with the groove at the top. See diagrams on pages 12-13 for further guidance.

11

Axle transducer sensor on a leaf spring Select a position to install the transducer sensor on a single axle leaf spring where:

• The transducer sensor is mounted to the top side of the spring. • The transducer sensor is parallel to the orientation of the chassis. This gives greater weighing

accuracy. • The transducer sensor is as far as possible from the axle. It can be mounted to the front or

rear of the spring with the cable running away from the axle. • The transducer sensor is mounted so the sensor is facing in the direction of the wheel. • The transducer is not at risk of damage from any part on the vehicle throughout the full

range of movement of the spring. • The cable can be routed to the reference box without risk of damage from any moving parts

and allowing for the full range of movement of the transducer on the spring. When mounting the sensor, ensure it is in the correct orientation, with the groove at the top. See “How to install a steel axle transducer sensor” below for further guidance.

How to install a steel axle transducer sensor A single axle transducer is used to monitor one side of an axle. Two axle transducers will need to be installed per axle, one on the suspension for the left wheel, one on the right. Ensure that you select the appropriate position for the sensor. As in the previous chapters. 1. Clean and dry the surface where the transducer will be mounted to the suspension system:

12

• On vehicles that have been used prior to installation of the weighing system, use brake cleaner and a Scotchbrite pad/s to remove any heavy debris.

• Use the alcohol wipes provided to ensure all grease is removed from the suspension component. Loose paint and rust must be removed. The site must be dry before installation

2. Ensure the mounting surface is at an appropriate temperature: • The ideal temperature of the mounting surface is 21°C. • If required, warm the spring with a hot air gun before bonding the transducer sensor. It is not

recommended to apply the bonding tape at temperatures below 15°C.

3. Warm the bonding tape in your hands and apply it to the appropriate side of the sensor: • The sensor must always be mounted with the face adjacent to the groove pointing up. • The sensor must always be mounted with the cable pointing towards the pivot point on the

suspension system. 4. Mount the sensor to the suspension and clamp in place for a minimum of 10 minutes. 5. As a ‘second fixing’ wherever possible to further protect the transducer sensor from debris that may dislodge it, strap the transducer sensor to the suspension component with two of the cable ties (supplied). 6. Note of the serial number of the sensor, the position it is located on the vehicle and the direction it is facing e.g. SN: xxxx, position 1, Front Right axle, facing Forward. Place the lowest number (of the serial number bar code) of the transducer in position 1 and the highest number in position 4. See page 14. This is to be noted in the “Weighing system connection table” on page 27. The cable is attached to the ‘REAR’ of the transducer. The opposite face is used to indicate which direction the sensor is facing (‘FRONT’).

13

If the front or rear sensors are mounted facing (‘sideways’) to the right or left, then N/A should be recorded in the “Weighing system connection table” on page 27.

8. Axle transducer position numbers In the section above, you are asked to note the serial numbers of the sensors. This is important for the calibration of the system, and the information must be noted for later reference in the “Weighing system connection table” on page 27. Mark each DEUTSCH Connector with its corresponding transducer sensor position number. You will need this when connecting to the reference box.

The axle layout is as follows: Sensor 1: Front Left. Sensor 2: Front Right. Sensor 3: Rear Left. Sensor 4: Rear Right. If looking from the top of the vehicle, this layout is in a letter ‘Z’ shape. For ease of identification later, position the transducer sensor with the lowest serial number in position 1 and the highest in position 4.

15

9. Running the cables under the vehicle To run the cable neatly under the vehicle the plugs can be removed from the transducer sensors. DEUTSCH Connector: Position 1: Brown Position 2: White Position 3: Blue Position 4: Black On the DEUTSCH Connector:

• Remove the orange wedge lock on the mating face of the connector with a flat blade screwdriver. Do not damage the seal!

• Release the locking tab on the cable pin by moving it away from the shoulder and then gently pull the cable from the rear of the connector.

To fit the cables back into the connector:

• Push the pin and cable squarely into the connector in the correct colour position until a “click” is felt and heard. Gently test pull the cable to ensure that it is located.

• Repeat this step for the further 3 cables. • Reinstall the orange wedge lock. This is pushed squarely into position until a “click” is felt and

heard.

The cables are to run under the vehicle from the transducer sensors to the reference box and from the reference box to the Modul Connect main box. The cables must be run through chassis rails where possible and cable tied to holes in the chassis/floor.

16

• Ensure the cables can be routed from each transducer sensor without risk of damage from any moving parts on the vehicle.

• Ensure that cable to cable connections are well supported. • Avoid running cables on or near sharp objects. • Keep cables away from hot components such as exhausts and engines. • Use the supplied cable ties to secure the cable to the chassis of the vehicle. • Do not fasten cables to original vehicle wiring, fuel pipes and brake pipes.

WARNING: Do not route other wiring near/close to electrical cables with the Anti-Lock Brake System and Traction Control System cables because of extraneous signal risk. It is generally not recommended to hang it off existing looms or pipes. If routing wiring through metal, all holes need to be protected by a grommet or Modul-System (part Number 19720-03) Convoluted Split Black Nylon Tubing 7.5 NW cable protector to avoid chafing. IMPORTANT: DO NOT CUT, SHORTERN OR MODIFY ANY YELLOW CABLE. This will affect the weighing system’s performance and give inaccurate readings. Examples of cable run under the vehicle:

17

18

10. Connecting the cables • Connect the cable to the reference box. • Ensure that cable to cable connections are well supported. • Use cable ties to secure any excess cable to the chassis of the vehicle. • Use Modul-System (part number 19720-03) Convoluted Split Black Nylon Tubing 7.5 NW 50M

cable protector to protect the cable at positions where it may be exposed to damage. The reference box has two ports. These are colour coded to ensure that only the correct cables can be connected to the correct port:

• Port with green tab. This is the connection for the first three sensors. Sensor information is transmitted from the sensors to the reference box via this port.

• Port with brown tab. This is the connection for the fourth sensor and ECU Interface Cable. Sensor information is transmitted from the fourth sensor to the junction box via this port along with the Information to the Modul-Connect main box.

Step by step installation

1. Connect the three-way sensor input cable to the green port on the reference box. 2. Connect the two-way sensor input and external domain connector cable to the brown port

on the reference box. 3. Connect the ECU Interface Cable from the Modul-Connect main box to the reference box

ECU cable.

Visually inspect the terminal locking tangs before pushing them into the Molex terminal housing. You can use the terminal extraction tool to carefully push out the tangs to their original position. If they are damaged in any way, replace the pin terminal. When inserting the Molex pin connectors into the Molex terminal housing, push the pin and cable squarely into the connector in the correct position until a “click” is felt and heard. Then gently test pull the cable to ensure that it is located and securely fitted/locked in the terminal housing. The tang faces to the center of the Molex terminal housing.

12. Configuring the main box with the app Find the vehicle weight plate. Each manufacturer chooses where to fit these, they are located on the driver or passenger door pillar or in the engine bay. The Picture below shows a typical Ford Transit Custom weight plate.

The vehicle weight details that are required are to the left of the chassis plate in the fur boxes under the Manufacturer, Type Approval and Chassis Number. 3200 kg is the Maximum Gross Vehicle Weight. This is the maximum permitted weight of the vehicle and any load carried in the vehicle. 5040 kg is the Maximum Train Weight. This is the maximum permitted weight of the vehicle and any trailer being towed, plus any load carried in the vehicle and trailer. 1625 kg is the Maximum Front Axle Weight. This is the maximum permitted weight at the front axle of the vehicle. 1725 kg is the Maximum Rear Axle Weight. This is the maximum permitted weight at the rear axle of the vehicle. The vehicle in the example above cannot be loaded to Maximum Front Axle Weight and Maximum Rear Axle Weight as this exceeds the Maximum Gross weight. This is a normal phenomenon on most vehicles. 1625Kg +1725Kg = 3350Kg Calibration Once the Modul-Connect On-board Vehicle Weighing System has been configured, it must be calibrated. This requires multiple weight measurements of the axles on the vehicle. Ensure that you know the Maximum Gross Vehicle Weight (GVW) before you calibrate the system. Two sets of vehicle measurements must be taken:

• Zero weights. This is the weight measurement of each axle when the vehicle is empty of load (racking etc. can be fitted).

• Span weights. This is the weight measurements for each axle when the total weight of the vehicle is as close to GVW as possible (tolerance +0 kg/-5 kg).

22

The zero weights calibration data should be entered into the APP when the vehicle is empty, and the zero weight measurements are taken. The span calibration data should be entered into the APP when the vehicle is at GVW and the Span weight measurements are taken. To set the Span weights, weight needs to be added to the load area to load the rear axle and to the cab area to load the front. Use the “Weighing system connection table” on page 27 to calculate required weight to be added. The weight measurements can be taken by using weigh pads or a weigh bridge. Vehicle weighing should be performed on a flat, level surface, in calm weather conditions. Where possible, weigh the vehicle indoors. Weigh pads: For accuracy and speed, it is recommended to use four weigh pads (one for each wheel) to weigh all axles at the same time. IMPORTANT: If only using two weigh pads, use levelling mats of the same height to maintain the overall level of the other axle which is not being weighed. Add together the weight measurements for both sides of the axle to calculate the current weight of the axle.

If using a weigh bridge, it must have a level approach.

1. Drive the front axle on the vehicle on to the weighbridge. 2. Take the weight measurement. 3. Drive the next axle on to the weigh bridge. 4. Take the weight measurement. 5. Subtract the weight of the front axle from the weight of both axles to find the weight of the

rear axle. It is recommended that the same weighing method is used to take all weight measurements for both the zero and span calibration processes. Images show applying weight to the vehicle and use of weigh pads:

• When applying weight to the rear of the vehicle, position this toward the bulkhead. This also loads the front axle so reduced weight is needed in the cab area.
