Tire Monitoring System Reference Manual System Scope of Use and Warnings The SmarTire System and Tire Maintenance This system is a sensing device designed to identify and display tire operating data and activate an alert or warning when pressure or temperature irregularities are detected. It is the responsibility of the driver to react promptly and with discretion to alerts and warnings. Abnormal tire inflation pressures should be corrected at the earliest opportunity. System Installation and Usage Use of the SmarTire system requires that it has been properly installed and programmed by qualified personnel according to SmarTire Systems Inc. documentation. This includes the Owners Manual and any supplementary installation instructions included with system components. THIS SYSTEM IS SUITABLE FOR USE IN PASSENGER AND LIGHT TRUCK TIRES UP TO MAXIMUM COLD INFLATION PRESSURE OF 85 PSI.. Use of Chemicals Temporary resealing or reinflation products containing internal sealers or propellants in any tire/wheel assembly may adversely affect the operation of Sensor Modules. Use of these chemicals can damage the pressure sensor and may nullify any manufacturers warranty, expressed or implied. Power Connection If your Display Module is connected to an unkeyed cigarette lighter socket unplug it when you park the vehicle for extended periods of time (more than three days) to avoid draining the battery. On a keyed circuit you will see the key lights turn off and the information screen clear when the ignition switch is turned off. Warnings 1. When an alert or warning conditions is detected, reduce vehicle speed to an appropriate safe level and proceed to a safe stopping location or facility where the tire can be inspected and serviced. 2. The pressure deviation alert indicates that the pressure has dropped a set amount below the required pressure. 3. The low pressure alert occurring shortly after a pressure status alert indicates that a rapid pressure loss is taking place. 4. The low pressure warning indicates that the pressure has dropped to a level considered critical to the tires ability to support and/or provide directional control to the vehicle. 6/20/2000 Page 8 of 56 This manual is under review by SmarTire DO NOT ISSUE SmarTire Systems Inc. Tire Monitoring System Reference Manual 5. The high temperature warning indicates that the contained air temperature has exceeded the selected maximum. A tire temperature buildup can be caused by a number of factors including severe under inflation, hard sustained braking, vehicle overload and sustained high speeds. 6/20/2000 Page 9 of 56 This manual is under review by SmarTire DO NOT ISSUE SmarTire Systems Inc.

(4 wheel) Product A

(2 wheel) Product H Overview These kits contain a base receiver, two or four strap mounted transmitters, installation hardware and documentation for use on tires with a pressure up to 83 PSI (gauge). The transmitters transmit pressure and temperature data when the vehicle attains a speed of 10 kph. Tire pressure and temperature are checked every six seconds and data is transmitted every 5 minutes. The receiver annunciates a pressure loss incident at two severity levels. The initial warning occurs when the pressure has dropped a set amount below the required pressure. A second warning occurs when the pressure has dropped to a level considered critical to the support of the vehicle. The affected tire is identified with a colour coded indicator on the receiver, corresponding to the same colour code on the valve of the respective tire. An optional serial port can send transmitter data to another customer device. To install the system use a supplied strap to mount the transmitter on the lowest part of the wheel well near the valve. Plug the receiver into the cigarette lighter plug with the supplied cable. 6/20/2000 Page 12 of 56 This manual is under review by SmarTire DO NOT ISSUE SmarTire Systems Inc.

Tire Monitoring System Reference Manual Receiver Operation Ensure the receiver is plugged in. After power is applied the lights flash red, green, then amber. They continue to flash amber until signals are received from the tire transmitters which transmit pressure data shortly after the vehicle starts to move (at speeds greater than 10kph).. Then all will turn off except the system light (left most light). The receiver is preset to initiate warnings at two levels of tire pressure. Typical settings are 24 PSI to initiate a Low Pressure Alert and 18 PSI to initiate a Low Pressure Warning. Check your kit documentation for the settings for your receiver. When transmissions are received amber tire lights turn off one at a time and finally system led turns green and stays on steady. System light is on green. Normal condition with no alerts on any tire. On Low Pressure Alert, there is a long beep, the tire light turns red and stays red. On Low Pressure Warning, the receiver beeps five times, with accompanying red light. Then red light flashes. After one minute receiver beeps five times. Continues until tire condition is corrected. Then light turns off. Programming the Receiver The factory settings for Low Pressure Alert and Low Pressure Warning can be changed with the multi-function display. When a new transmitter is installed its ID must be programmed into the receiver for it to be able to receive data. This is done with the Learn Mode of the multi-function display. 6/20/2000 Page 24 of 56 This manual is under review by SmarTire DO NOT ISSUE SmarTire Systems Inc.

Tire Monitoring System Reference Manual Detecting Abnormal Tire Pressure The MFD alerts the driver of abnormal tire pressure with a Pressure Deviation Alert or a Low Pressure Warning. Understanding Temperature Compensated Pressure Readings An important feature of the SmarTire (MFD) system is that pressure alerts are initiated from a temperature compensated pressure calculation rather than on the actual pressure read by the sensor. The reference pressure, or cold pressure is the air pressure inside the tire inflated at room temperature (18 C) to the tire manufacturers recommendation. A tire that heats up, for example to 28 C, will increase the air temperature inside the tire, resulting in increased air pressure. For example a normal or required pressure at 18 C may be 34 PSI and a normal pressure at 28 C may be 36 PSI. Both pressure readings are correct at their respective temperatures. The amount of deviation from the required pressure (at any temperature) can be read by using the Pressure Deviation mode of the MFD. If at any time you are uncertain that the Actual Pressure reading on the display indicates the correct tire pressure, switch to the Pressure Deviation (+-) readout. A blank display indicates that the reading on the display is the correct one. Any (+) or

(-) value indicates the tire pressure is incorrect by that value. The Pressure Deviation Alert is temperature compensated. The Low Pressure Warning is not temperature compensated. 6/20/2000 Page 40 of 56 This manual is under review by SmarTire DO NOT ISSUE SmarTire Systems Inc. Tire Monitoring System Reference Manual Pressure Deviation Alert Low Pressure Warning The Pressure Deviation Alert is initiated when the actual pressure of a tire deviates by more than the amount programmed for the vehicle. For example this will occur if the MFD is set for +- 2 PSI and the actual pressure drops to 24 PSI (from the required pressure of 34 PSI). The MFD issues one beep. The alarm light and alert icon flash on and off. The digital readout displays the amount of deviation (-

12 PSI) from required pressure. Press any button to stop the flashing and leave the alarm light on. A Low Pressure Warning is initiated when the actual pressure drops below the value programmed for the wheel on that axle. For example if the setting is 26 PSI for the rear axle and an actual pressure of 24 PSI is detected, the MFD will initiate a Low Pressure Warning. The beeper turns on and off continuously and the alarm light flashes. Press a button to stop the beeping and flashing. The display reverts to standby with the alarm light on. Press the tire button to find the affected tire. The flat tire icon, the alert icon, PSI, the pressure reading and alarm light will all be on. 6/20/2000 Page 41 of 56 This manual is under review by SmarTire DO NOT ISSUE The High Temperature Alert is initiated when the temperature from a transmitter exceeds the programmed setting.

Alligator Valve Selection Process and Verification of Proper Assembly Fit Internal Visual Inspection of the Wheel or Rim 1. Confirm location of drop-center:

Is it nearer to front or back side of the wheel?

If near front, use the strap mount sensor. If near back, continue. 2. Confirm location of the valve:

Is it beside the drop-center well, but at no more than a 10-degree angle?

If more than 10-degrees, use the strap mount sensor. If close, then continue. 3. Confirm diameter of valve hole in the wheel:

Is it 0.453 (11.6MM)?

[The only next closest standard sizes are 0.327 (8.38MM) and 0.625 (16.03MM)]

If smaller/larger, use the strap mount sensor. If confirmed 0.453 (11.6MM) diameter, then continue. 4. Confirm available clearance for the valve attachment nut:

Is there 0.625 (16MM) diameter?

[This clearance is adequate in most cases, but there are some wheels in the market where we have found the anchor nut and washer to be 0.060 (1.5MM) too large.]

If less, then use the strap mount sensor. If more, then continue. 6/20/2000 Page 43 of 56 This manual is under review by SmarTire DO NOT ISSUE SmarTire Systems Inc. Tire Monitoring System Reference Manual 5. Confirm maximum rim thickness at valve clamping area:

Is it 0.156 (4MM)?

[Normally not a problem with a 0.453 diameter valve hole]

If greater, then use the strap mount sensor. If less, then continue. 6. Confirm depth of the drop-center well near the valve hole:

Is it 0.67 (17.3MM) below the humps of the bead seats?

If shallower/deeper, then consider using the strap mount sensor. If OK, then continue. 7. Confirm width of the flat base of the drop-center well:

Is it at least 0.85 (22MM)?

If less, then installation of either the valve or strap mount sensor may not be possible. If OK, then continue. 8. Confirm relative position of the valve grommet-sealing surface of the valve hole of the adjacent side or top edge of the drop-center well:

Is valve hole recessed 0.25 (6MM)?

If recessed considerably more, then use the strap mount sensor. If essentially flush or less, then continue. Minimum drop centre width =.85 Wall angle 10 degrees Transmitter attachment screw Minumum drop-centre depth = .67 3"

Tire Monitoring System Reference Manual 1. Start by using the valve assembly with longest of the three bases (Alligator #59.0054) 2. Remove the sensor attachment screw and install the valve body (into valve hole from the front side), washer and nut. Finger-tighten the nut until grommet is evenly seated. Make sure the fit of the valve body/grommet and the clearance of the washer/nut with respect to wheel. 3. Place the sensors spherical mounting surface against the matching surface of the valve. Pivot the sensor housing toward the bottom of the drop-center well until both contact pads rest on the wheel. Confirm that the sensors only contact with the wheel is at the two contact pads. Note the clearance between the sensor housing and the side of the drop-

center well, including the bottom radius. This space should be approximately 0.080

(2MM). If clearance is greater than 0.25 (6MM), consider using a valve with a shorter base. If the clearance is between 0.25 and 0.44 (6.7MM and 11.3MM), switch to the valve assembly with the next shorter base (Alligator #59.0044). If the clearance is greater than 0.44 (11.3MM), then utilize the valve assembly with the shortest base (Alligator #59.0034). If no additional valve selections are available, then use the strap mount sensor. 4. Repeat the above procedure to verify housing clearance at both the top and bottom of the drop-center well. 5. Check the position of the valve attachment hole in the base of the valve body relative to the housing adjustment slot:

Is hole completely visible with the housing firmly seated against both the wheel and valve?

If the hole is not completely visible, then use the strap mount sensor. If the hole is completely visible with some adjustment remaining, then continue. 6. Tighten valve anchor nut to a torque value of 36 in.-lb. (4+/-0.05Nm).

[Note: It is very important to tighten the valve anchor nut to the defined torque value prior to tightening the sensor attachment]

7. Assemble sensor housing and attachment screw onto the base of the valve. Before tightening, hold sensor housing snugly against both the valve and the bottom of the wheels drop-center well. Tighten the sensor attachment screw to a torque of 36 in.-lb.

(4+/-0.05Nm). Visually confirm that clearance remains between the top and bottom corners of the sensor housing and the wheel surface. 6/20/2000 Page 45 of 56 This manual is under review by SmarTire DO NOT ISSUE SmarTire Systems Inc.
