5 1 - VIGIA AUTOMATIC TIRE PRESSURE SYSTEM Features: It allows for constant and automatic monitoring and adjustment of tire pressures. The system maintains a predetermined cold pressure, even in a moving vehicle or a vehicle with punctured tires. The VIGIA NM343 display module generates digital information on the status of tire pressures and system that is transmitted via its interface to the existing vehicle s satellite module and ultimately to the user s telematics software. Operation: In the event of a 3 or higher PSI decrease in the pre-established pressure in one or more tires due to punctures or other causes, the system automatically generates audio and visual signals that inform the driver of the problem and its location. At the same time the system begins pumping air, keeping tire pressures calibrated at the pre-set levels. If the loss of air is substantial, as in the case of a blow-out, and the equipment is not able to compensate for this loss, a visual signal advises the driver. At the same time, an electronic security mechanism blocks the equipment, stopping the system from pumping air, thus ensuring the normal operation of the other airdriven systems: brakes, suspension, etc. Model NM343 can be installed in all vehicles equipped with an air compressor. System components, operation and installation procedure are described in the following sections. 1

6 2 - SYSTEM COMPONENTS ROTOR MOUNTINGS VIGIA provides different rotor mountings for different hub types. A) DISKS To install the disks, replace nuts or bolts in the hub with Vigia stud bolts according to the Table in next page (Fig. 1). Vigia stud bolts are available for different thread sizes and lengths. Figure 1 One of the disk's faces has dash lines identified by numbers in the outer edge. These lines will be used for drilling and centring (Fig. 2). Figure 2 2

7 INSTALLATION PROCEDURE 1- Determine the quantity of nuts or bolts in the hub. 2- Assign a number to each one, # 1 corresponding to the one in the highest position, numbering the rest clockwise. The following table shows all possible hub clamp nut or bolt quantities in the first column. With this information, determine the necessary stud bolt quantity (column 2), the nuts or bolts to be replaced (column 3) and the disk lines to be drilled (column 4). Hub nuts or bolts - quantity Stud bolt quantity Nut or bolt numbers to be replaced Disk lines to be drilled * * * *Note: If the hub has 0.8 mm or 5/16" bolts and ornamental cap, 4 stud bolts must be used. 3- Replace the nuts or bolts specified in column 3 of the above table by the stud bolts provided with the system. 4- With a compass, measure clockwise the distance between the centre of the stud bolt replacing the bolt or nut assigned # 1, and the centre of the next stud bolt. 5- Mark that measurement on the disk to be used, onto the lines given in column 4 in Table 1, carefully placing one of the compass' ends in lines 0 or Repeat steps 4 and 5 as many times as necessary until all points to be drilled have been marked. All the selected drill points must be located at the same distance from the disk's outer edge. If the distance measured with the compass falls in between two points, mark a third point between the other two points, maintaining the original distance. 7- Drill the selected points with a 0.5 mm (13/64") bit first, and then with a mm (13/32") bit. 3

8 DISK FASTENING EXAMPLE An axle with a 10-nut hub is shown. The fastening nuts are numbered as specified in step 2 (Fig. 3). Figure 3 From Table 1, it is determined that for a 10-nut hub, 3 stud bolts should be used to replace nuts numbers 1, 4 and 8, which must be taken out and replaced with the stud bolts provided with the system (Fig. 4). Figure 4 The distance between the centre of the stud bolt that replaced nut # 1 and the centre of the next stud bolt is measured (Fig. 5). Figure 5 4

9 In this example, Table 1 shows that the dashed disk lines to be used are numbers 0, 4, 4. Therefore, with the centre on a point on line 0, the rest of the points are placed on lines 4, obtaining three reference points at the same distance from the disk's outer edge (Fig. 6). Figure 6 The selected points are drilled, fastening the disk to the stud bolts with the washers and nuts provided (Fig. 7). Figure 7 B) STARS This element can replace the disks in units whose hubs have 3, 6, 9, 12, or 15 fastening nuts or bolts. Three of the nuts or bolts must be replaced by Vigia stud bolts that are provided with the system (Fig. 8). Vigia stud bolts are available for different thread sizes and lengths. Figure 8 5

10 INSTALLATION PROCEDURE 1- Determine the quantity of nuts or bolts in the hub. 2- Assign a number to each one, with # 1 corresponding to the one in the highest position; continue clockwise numbering the rest (Fig. 9). The following table shows all possible hub clamp nut or bolt quantities in the first column. With this information, determine which nuts or bolts will be replaced. Fig. 9 Hub nuts or bolts quantity Nut or bolt numbers to be replaced Replace the nuts or bolts specified in the second column of the table by the stud bolts provided with the system (Fig. 10). Fig With a compass, measure the distance between the centres of two stud bolts (Fig. 11). 6 Fig. 11

11 5- Apply the measurement to two of the star spokes, marking the points. Then, using one of the marked points as a reference, apply the measurement to the third spoke (Fig. 12). Fig. 11 The selected points must be located at the same distance from the star's outer edge. Fig. 12 If the distance measured with the compass falls in between two points, mark a third point between the other two points, maintaining the original distance measurement. 6- Drill the selected points with a 0.5 mm (13/64") bit first, and then with a mm (13/32") bit. Fasten the star to the stud bolts with the washers and nuts provided (Fig. 13). Fig. 13 C) THREADED CAPS This element is used in units with a threaded cap hub. INSTALLATION PROCEDURE 1- Take the original threaded cap out (in models with oil, first collect the oil in a clean container). A 2- Secure the provided VIGIA threaded cap in place. It must be the one specific to the unit. The model with a central hole is for units carrying oil. Replace the oil through the central hole in the threaded cap. Install the plug (A). 3- Put the disk or star in place, fastening it with the stud bolts, nuts or bolts provided. 7

12 D) BRACKETS FOR STEERING WHEELS Various rotor mounting kits for steering axles are available. Do not remove original lug nut form wheel. Always attach the bracket over the wheel nut with the provided nut ROTOR (Fig. 23) The rotor's purpose is to allow air to pass from a stationary point on the truck body to the rotating tires. Fig. 23 INSTALLATION PROCEDURE The rotor must be tightened with moderate torque, approximately 6 Lb./Ft. (Fig. 24). Note: The rotor output terminals must be oriented towards the inflation valves. Fig TIRE VALVES VIGIA offers different tire valves. All tire valves have a check valve at their brass end preventing air to escape from the tire. a) Hose and Tire valve 50 cm (Fig. 25): for inside tires in dual-tire configurations. b) Hose and Tire valve 30 cm: for outside tires in dualtire configurations or for single tires.

26 2.5 - HOSE INSTALLATION PROCEDURE Given the vast variety of vehicles on the market today, the hose installation will be subjected to the installer's criteria. Nevertheless, the following recommendations will facilitate and optimize the installation: 1- Use only the hose provided with the system. 2- Secure the hose approximately every 40 cm (16"). If the fastening is near brake air pipes or electrical connections, use the straps provided. If the fastening is on the chassis or body, use the special clips and clamps also provided. 3- Drill the required holes with care. Be sure not to damage pipes, tanks, electrical components, etc. 4- Do not install hoses near heat sources (mufflers, heating pipes, etc.) or moving parts (steering, suspension, cross-arms, etc.). 5- Near body couplings, secure the hose at shorter lengths, so that if a clip or a clamp gets loose, the hose does not come into contact with the tire. 6- If a body coupling is too close to the wheels and it becomes necessary to bend the hose in a 90- degree angle, use an elbow connector (provided). To install it, insert a piece of hose into the body coupling terminal and cut it flush, so that it works as a joint to prevent leakage A O ring can be used instead.(fig. 53). O RING Fig. 53 5/16" HOSE 22

27 GENERAL DIAGRAM A tractor and trailer is shown. NM 343 CONNECTION PROCEDURE The VIGIA system comes with a full range of joints (Fig. 63) to satisfy multiple needs. The coupling between hose and joints is similar in each case, and a fastening nut is always provided to prevent the hose from being disconnected. Connect the hose to the couplings on both sides of the axles, joining them with a T or a cross joint and then to the hose connecting to the control module. Fig. 63 Coupling between tractor and trailer (Fig. 64). 23

28 For this coupling, a connection set is provided (Fig. 65). Installation procedure: a) Affix the end that has the 5/16" straight chassis joint (A) to the tractor in a location near the brake hose connection. If necessary, use the mounting provided (E). b) Affix the connection hose mounting with its cap (B) in an easy-to-reach location near the straight joint (A). c) Affix the fixed connection valve (C) to the trailer, in a location near the brake hose. d) Insert the hose end with connection valve (D) to the fixed connection valve (C) (Fig. 66). Fig. 65 e) When detaching the tractor from the trailer, disconnect the hose end with connection valve (D), and connect it to the hose mounting (B) located on the tractor. Place the cap on the fixed connection valve (C) on the trailer. 24

29 2.6 - AIR FILTER (Fig. 84) Purpose: To filter the air entering the VIGIA system, retaining solid impurities and water condensation, which are returned to the compressed air tank. Location: 1) Select a secondary air tank in the truck or bus operating at the same pressure as the compressor. Avoid using the tank feeding the brake system. 2) Locate a plug, connector, hose or coupling on the output line of the tank or distribution line, where a connector (provided) will be placed. 3) Determine a location for the air filter on the body or chassis providing that: a) It is located at the top of the connector or joint so that the 5/16 hose is vertical (Fig. 85) and not trapping air (Fig. 87). b) It is secured vertically to the body or chassis. c) It is as close as possible to the tank, so that retained liquids return to it. Fig. 84 Fig. 85 Important: Foresee possible movements between the filter and the air tank. Fig. 87 Installation procedure Very Important: Use the manual draining of the air tank to depressurize completely. Never unscrew completely an air tank plug. could produce serious injuries.

34 Operation 30

35 1 - System Activation The system turns on automatically when the vehicle s contact key is on. With contact key off and pressing for 4 seconds, the system will turn on the display and show tire pressures but the system will not be operational i.e. it will not inflate tires if needed. 2 - Display Tire pressures can be displayed in sequential or manual mode. Sequential Mode (default setting): Each circuit pressure is displayed for 10 second sequentially. 10 SECONDS 10 SECONDS 10 SECONDS Manual Mode: In Manual Mode circuit pressure and air tank pressure (P) can be displayed pressing or.. To turn Manual Mode on or off press the key or for 3. seconds. Important: The display goes into sequential mode automatically when loss of pressure is detected and it will show the circuit being inflated. 3 - Air Leaks The Vigia System, if activated, will automatically start inflation to a circuit with 3 or more PSI differential between actual and set tire pressure. Depending on the magnitude of the air loss, the system will warn the driver differently: a) 3 PSI drop takes more than 1.5 minutes to generate: System will automatically compensate the air loss but no alarm or warning will be produced. b) 3 PSI drop takes 1.5 minutes or less to generate: Automatic inflation, turns on intermittently and one beep every 9 seconds. 31

36 c) 3 PSI drop takes 30 seconds or less to generate: Automatic inflation, turns on intermittently and two beeps every 5 seconds. d) 3 PSI drop takes 2 seconds or less to generate: Automatic inflation, turns on permanently and three beeps every 2 seconds. Note: It there are air leaks in two or more circuits, only those circuit pressures will be displayed and in sequential order. In Manual Mode when an air leak is detected the system automatically turns to Sequential Mode and displays the circuit/s being pressurized. 4 Excessive Loss of Pressure If the air leak is too big and the vehicle s air compressor cannot compensate for it, the system will turn off automatically and will display the air tank pressure (P) warning the driver with 3 beeps every 2 seconds. Factory setting for the air tank pressure (P) warning is 80 PSI 5.5 BAR. 5 Alarm OFF Press to turn the alarm off. If turning the alarm off when the system is inflating one or more circuits, the alarm will automatically reconnect after 20 minutes. 6 Circuit Deactivation To temporarily deactivate a circuit proceed as follows: a) Turn display to Manual Mode pressing or for 3. seconds. b) Select the circuit to deactivate using or.. c) Press to confirm. A beep and the circuit number blinking is confirmation that the circuit has been deactivated. To cancel deactivation turn contact key off and on. 7 Dimming Display To decrease/increase display luminosity keep pressed the key until desired level. 32

If the film is damaged or removed, protect both terminals with electrical tape as shown in the figures. Connection to Satellite Module The Vigia electrical connection provides the wires that relay the digital information to the existing satellite module in the vehicle (please see diagram above.). Specific connection instructions should be requested to the telematics systems provider. 4 -TIRE PRESSURE CALIBRATION Before tire pressure calibration, make sure that: 1. Tires are cold (ambient temperature at least 4 hours after rolling). 2. Air tank pressure is at least 10 PSI higher than the maximum desired tire pressure. To assure this is the case, proceed as follows: a. Drain air tank completely. b. Connect the hose end from the air filter to a gauge. c. Start the engine and verify in the connected gauge that the compressor cut-off pressure is a minimum of 10 PSI higher than the maximum desired tire pressure. If that is not the case, increase the pressure using the compressor's governor. d. After this procedure, disconnect the gauge. 36

41 Tire Pressures can be set up to 160 PSI (11 BAR). CALIBRATION 1- Turn the ignition key to contact. 2- Insert the Calibration Tool into the control for calibration and press for four seconds until a continuous beep. Display is now in calibration mode. CALIBRATION TOOL. 3- Using or select PSI or BAR. Then press the calibration button. 4- Circuit 1 is shown. Using or set the desired pressure. Then press the calibration button.. 5- Circuit 2 is shown. Using or set the desired pressure. Then press the calibration button.. 6- Circuit 3 is shown. Using or set the desired pressure. Then press the calibration button.. 7- Air tank pressure is shown. Factory setting is 80 PSI (5.5 BAR) and this value should not be changed. Press the calibration button for 3 seconds until a beep is heard. Display is now in Sequential Mode. 37

42 5 - FINAL SYSTEM TESTING (in operation) 1- Verify that there are no air leaks in the system by turning off the system. If there are any leaks, the pressure readings will drop. To detect air leaks, use soapy water and monitor all connections and joints. Note: To facilitate detection of small air leaks, isolate the system network by sections through the use of plugs. 2 - Verify the operation of the safety mechanism by producing a very large air leak (For example, take a plug out, press the brakes repeatedly, etc.) - The Air Tank (P) pressure will be shown and the alarm will sound. 3- Confirm that air is reaching each tire. 4- Verify, after a few minutes, the correct pressure readings with respect to the set calibration. 5- Clean all the working surfaces. 6- Control the adjustment and aesthetics of all the elements: fastening nuts, hoses, body couplings, etc. 7- Verify that there are no air leaks in the air filter. 38

43 6 - RECOMMENDATIONS TO THE INSTALLER 1- Explain to the user how the system works. Provide the user with the following elements: User's Manual, N/F 3/8" plugs, straight joint 5/16", fastening nuts and hose provided with the system. 2- Inform the user that each time a tire is replaced it should have a pressure lower than the calibration pressure. The system only provides air to tires, it does not deflate tires. 3- Remind the user that rotor centring must be checked each time that a hub is dismounted to repair the brakes, to make bearing adjustments or replacements, etc. 4- Remind the user that the excess pressure generated by rolling must not be higher than 12% of the cold calibrated pressure. If the display indicate a pressure higher than that percentage, the user must verify whether the pressure is generated due to system failure or by rolling, proceeding as follows: - Disconnect one or more tires from the system. - Drive until display readings for connected tires exceed the specified tolerance. Compare pressures of connected and disconnected tires with a tire gauge. - If the pressures are similar, rolling causes the increase. If pressures differ, there may be damage to the control module. See "Failure location guide" in next section. 7 - FAILURE LOCATION GUIDE To quickly trace an air leak turn the system off and: a) If the display reading falls quickly, the leak is located in the system network between the VIGIA tire valve and the control module. b) If the display reading falls very slowly, the leak is located in the tire (puncture) or a VIGIA tire valve is defective or loosely attached to the tire stem. PROBLEM PROBABLE CAUSES SOLUTIONS Loss of pressure in display. With the system disconnected, the reading falls slowly. 1-Small pressure loss in one or more tires. Punctured tire. 2-Small loss between the original tire valve's thread and the VIGIA tire valve. 1 - Repair the affected tire. 2 -a) Adjust the VIGIA tire valves lightly with a wrench. b) Replace the VIGIA tire valve's joint. c) Check the original and VIGIA valves' thread (clean with a threading tool). Replace if necessary. 39

44 Los of pressure in display. With the system disconnected, the reading falls quickly. 1. Loss of pressure in the system network, between the tire valve and the control module inclusive, caused by: a) Worn out or defective rotor. b) Deteriorated hose. c) Couplings, connectors, joints, etc. d) Connection valves between the tractor and the trailer. 1. a) Replace the rotor. b) Replace the affected hose length. c) Tighten or replace the affected element. d) Replace the seal in the fixed joint valve. Display indicates more than 12% from the set calibration without alarm or warningsafter having rolled the unit. 1-Overheating caused by lower calibration than the one set by tire manufacturers. 2-Tire(s) with pressure higher than the one calibrated for the system. 3-Uneven load distribution. 4-Mechanical defects (mallets with worn or broken spring, misaligned axles, etc.). 5-Speeding. 6-Inadequate tires for the type of load. 7-Control module damage. 1-With cold tires reset the VIGIA system to the pressure indicated by tire manufacturers. 2-Deflate the tire(s) to a pressure lower than the calibrated one. The system will reset the tire(s) again. 3-Distribute the load correctly. 4-Repair the mechanical defects. 5-Slow down. 6-Replace tires with adequate specifications. 7-Replace control module. Display indicates higher than calibrated pressure, with alarm and warnings on. 1-Display calibration altered. 2-Display module damage. 1-Deflate the tire(s) to a pressure lower than the calibrated one and adjust the VIGIA Display Module again. 2-Replace Display module. 40

45 With on, the system is not inflating to the set pressure. 1-Insufficient pressure in the air tank (which must be 10 PSI higher than the maximum set pressure) caused by: a) Incorrect tank selection for air supply to the control module. 1- a) Correctly select air tank according to installation instructions for the air filter. b) Defective compressor operation. c) Compressor cut-off valve with low calibration. 2-Obstructed Air Filter. b) Repair compressor. c) Adjust the compressor cutoff valve. Repair if necessary. 2-Clean the air filter. 3-Strangled connecting hose between air tank and control module. 5-Control module damage. 3-Replace hose. 5-Replace control module. Pressure falls and system does not recover Indicator off. 1-Calibration altered. 2-Display module damage. 1-Calibratet the VIGIA Display Module again. 2-Replace display module. The air continues to leak from the tires while disconnecting a hose from the network. 1-Leak in tire valves. 1-a) Activate the valve's internal piston with a blunt element. b) Take the valve out and blow through the intake end, adding soapy water. Check for closing tightness, and replace if necessary. With the system disconnected, air leaks from the control module while disconnecting a hose from the network. 1-Control Module damage. 1-Replace control module. 41

46 When disconnecting trailer from truck, turns. on. 1-Leak in the fixed connection valve. 1-a) With the system in operation, activate the valve piston. b) Disconnect the system, disconnect the hose and blow on the other end, adding soapy water. c) Replace if necessary. Deflated tire and display indicating correct pressure. 1-Obstructed rotor, body couplings, hose, tire valve, connectors or joints. 2- Control Module damage 1-Replace affected element. 2--Replace control module. Display shows E --- (error code). Communication errors between control and display modules caused by: 1-Faulty connection at either end of the electrical cable. 2- Dirty connectors. 3- Connector with broken pins. 4- Electrical cable damaged. 5- Control or Display module damaged. 1- Verify and correct. 2- Clean using air gun. 3- Replace module. 4- Replace cable. 5- Replace Control or Display module. 42
