TPMS Lite Installation Guide ST542119‐001 2. TPMS Lite Antenna Installation _________________________________________________________ Introduction This section will describe the fitting of the TPMS antennas to a vehicle. Please ensure you read this guide carefully to obtain the best performance out of the system. Antenna Details The antenna is an advanced single band antenna. For optimum system performance care should be taken to fit the antennas according to the guidelines in this document. The system performance can be impaired with poor antenna placement. The goal of choosing an antenna position is to achieve the strongest signal strength over the widest wheel rotation. There will be some points of wheel rotation where a signal will not be strong enough to take a measurement. These are generally called NULLS. It is common to have 3 nulls per rotation of the wheel. Each antenna is supplied with a strip of hook and loop tape. It is recommended that the antenna is mounted with this. Antenna Installation As previously mentioned the goal of the antenna installation is to achieve the strongest signal strength over the widest possible rotation angle of the wheel. To help it is best to use the supplied TPMS Config software monitor mode. The important parameter to monitor is the SAW Strength value. This will give you real‐time feedback of the signal strength from the sensor. Please refer to Section 3 of this document for further information on TPMS software configuration. 9 ...
Page 10
TPMS Lite Installation Guide ST542119‐001 Saw Strength The antenna installation is normally done in several parts. The first is to choose an initial location and measure the signal strength during a complete wheel rotation. This will give a baseline to work from. Then the process is repeated with a new antenna position. Each time the goal is to increase the wheel rotation coverage or signal strength. You should be aiming to get at least ¾ of the wheel covered at greater than 70% signal strength. However the more strength or coverage you achieve the better the system will perform. NOTE: It is worth spending the time at this stage to find the optimum antenna position as it will significantly reduce the potential for problems later on. The antenna has a plastic side and an epoxy potted side. It is important that the plastic side is facing the wheel and sensors. All antennas are affected by the surrounding environment. Wishbones, pushrods and other suspension and steering parts can all influence the performance of the antenna. However the impact of these can be kept small with carful antenna positioning. Do • The plastic side of the antenna must face the wheel and tyre. • The antenna should be mounted with a clear line of sight between itself and the wheel. • The antenna should be mounted less than 60cm from the wheel. • The antenna should “look” through the sidewall of the tyre. • The antenna should be mounted using the supplied hook and loop tape. Do Not • DO NOT mount the antenna behind metal or carbon body work. • DO NOT Stick anything to the plastic face of the antenna. • DO NOT paint the antenna. • DO NOT mount the antenna too close to high temperature parts (e.g. exhausts) 10 ...
TPMS Lite Installation Guide ST542119‐001 Mounting Examples The following is an example of starting placements for the antenna. Excess Cable To further increase the performance of the antenna it is advised to coil the excess antenna cable up in a specific way. • First loop the antenna cable up Now squeeze the cable together and secure with 2 cable ties. 11 ...

TPMS Lite Installation Guide ST542119‐001 Read Config Read Config Config Status CAN Configuration The TPMS interrogator has a fully configurable CAN bus output. This is used to send data to the TPMS gauge and can also be used to connect the system to a data logger. Note: The gauge is fixed to received CAN data on ID 1440 (FL), 1441(FR), 1442(RL) and 1443(RR). The gauge expects and will only function with these CAN IDs. Wheel CAN ID To configure the CAN options click on the tab. CAN IDs CAN Receive ID Gauge Fitted CAN Bit Rate • CAN IDs The interrogator outputs a CAN data message per wheel. By default the interrogator outputs on IDs 1440 to 1443. These are the IDs the TPMS gauge reads. The CAN IDs can be changed to suit the system the TPMS is connecting to. 14 ...
TPMS Lite Installation Guide ST542119‐001 • CAN Receive ID The TPMS interrogator can receive data over the CAN bus. • Display Fitted Unchecking this option stops the TPMS interrogator sending the CAN messages to the gauge. This is useful if the gauge CAN IDs are taken by another device on the system and should not be sent out by the TPMS interrogator. Checking this option allows the CAN IDs of the interrogator to be changed while keeping the gauge functionality. • CAN Bit Rate The bit rate of the TPMS interrogator can be selected. If the TPMS system is not being connected to an external data logger then this can be left at 1Mbit. If the system is being connected to a data logger, set this to the bit rate of the system you are connecting it too.

TPMS Lite Installation Guide ST542119‐001 The wheel set configuration can be written to the box by pressing the write config button. Misc. Options The “misc.” options allow the user to configure the way the atmospheric compensation and out of range values are handled by the interrogator. The atmospheric compensation value can be handled by setting the atmospheric pressure manually. This is typically done at the start of each day. It is also possible to send the interrogator the atmospheric pressure over the CAN link from an existing logger. In this mode the compensation can be more accurate as it compensates in real time from an existing sensor reading. The CAN spec is covered in Section 5 of this document. The out of range values tell the interrogator how to handle a loss of signal from a sensor. Should a sensor become damaged and the interrogator is unable to read temperature and pressure from it after 10secs the interrogator will set the output from that channel to either of the two following states: • Hold last Value this keeps the last value that was successfully measured with the sensor on the output until the sensor can be read again. • Default Pressure/Temperature this will force the output to the values defined if the sensor cannot be read. For example this can be set to a large value outside normal operating range so it is very clear when the sensor is not being read. 22 ...

TPMS Lite Installation Guide ST542119‐001 Corner Indicators In normal operation the gauge will display the status of the tyres via 4 LEDS on each “corner” of the gauge. These corners are positioned on the dial to reflect the real life position of the wheels on the vehicle this allows for quick “at a glance” feedback. The coloured LED descriptions are as follows: LED Description Red Alarm state present on Corner Green Wheel OK Blue Low Temperature* Amber No sensor detected in wheel Red LED ‐ will illuminate if the gauge detects an alarm state on that corner. If the red LED is illuminated you should be aware that one of the parameters is now outside the thresholds set. Green LED ‐ indicates that the wheel is working within the thresholds set. Blue LED ‐ illuminated when the temperature is lower than the low temperature threshold. *The blue LED will illuminate when the LOT menu (see Configuration Menus on Page 3 for details) is set to “ind” and the measured temperature is below the low temperature threshold. Amber LED ‐ will illuminate when the system does not detect a sensor in the wheel. If a sensor is fitted then please refer to the troubleshooting guide. 26 ...
TPMS Lite Installation Guide ST542119‐001 Alarms The gauge features a configurable pressure and temperature thresholds for each of the wheels.
