TPMS Lite Installation Guide ST542119-002 1. TPMS Lite Sensor Installation _________________________________________________________ Tools Required The following tools will be required for the fitting process: Torx (R) T20 Screwdriver /Torque driver (RS 662-608, DemonTweeks BIKTORXKEY) 4Nm Torque screwdriver ¼” Drive (e.g. Teng Tools 1492SD) 11mm x 50mm Socket (e.g. - Page 4 TPMS Lite Installation Guide ST542119-002 Valve Fitting Ensure the wheel rim is cleaned and degreased around the valve and wheel well (Green area). Insert valve into wheel rim. Fit the spacer ring (D) and then the collar nut (E) finger tight.
- Page 5 TPMS Lite Installation Guide ST542119-002 Insert the installation bar (G) into the valve body and tighten the collar nut (E) to a torque of 4Nm +/-0.5Nm Press the sensor down into the wheel well so that base of the sensor is touching the rim.
- Page 6 TPMS Lite Installation Guide ST542119-002 Tighten the Torx screw (A) to 4Nm +/- 0.5N Once tightened check the sensor is still in contact with the rim.
- Page 7 TPMS Lite Installation Guide ST542119-002 The sensor is now fitted correctly to the rim and ready for the tyre mounting. NOTE: It is recommended to fit some identifying mark on the outside of the tyre to indicate the rim is fitted with a TPMS sensor. This will alert tyre fitters to the fact there is a sensor...

Page 9: Antenna Details
Antenna Details The Stack TPMS antenna is an advanced Dual-Band Antenna (DBA). 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. - Page 10 TPMS Lite Installation Guide ST542119-002 The antenna must be mounted radially from the centre of the tyre. The Ground plane can point towards or away from the centre of the wheel. The antenna can be mounted behind NON conductive panels (Kevlar, GRP) In a typical installation you will achieve 90-120deg of RFID coverage and 270 degrees of SAW coverage.
- Page 11 TPMS Lite Installation Guide ST542119-002 The SAW_Strength and RFID_Strength indicators can be used to tune the antenna position. Antenna Placement The antenna installation is normally done in several parts. The first is to choose an initial location for the antenna based on the above guidelines and measure the signal strength during a complete wheel rotation.
- Page 12 TPMS Lite Installation Guide ST542119-002 Antenna Placement Restrictions If you have to mount the antenna to a conductive surface (metal, carbon) then you MUST space it off the surface by 10mm. Dual lock is ideal for this. Should you have to mount the antenna behind a conduction surface then please ensure that you cut a window for the antenna that is the same as the dimensions below.
- Page 13 Keeping a hard copy log during antenna installation is a useful way of capturing the data in the field but can also be helpful in aiding a Stack engineer diagnose possible problems with an installation. A sample log may look like this:...

TPMS Lite Installation Guide ST542119-002 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. - Page 19 TPMS Lite Installation Guide ST542119-002 The Monitor window displays the values from each of the 4 wheels. The monitored parameters are listed below. Parameter Range Optimum Description Pressure 0-320psi Measured pressure Temperature 0-320DegC Measured temperature System Status Green No Sensor Detected...
- Page 20 Importing Sensors The TPMS Lite system allows for 3 sets of wheels to be configured. Each set can contain up to 4 sensors. The sensors need to be imported to the TPMS sensor library before being configured for use in the box.
- Page 21 TPMS Lite Installation Guide ST542119-002 The configuration utility will scan the directory and list the sensors that are available for importing. You can identify the sensors you have by looking at each sensor’s individual label which has its id printed on it.

Page 27: Connection And Setup
The TPMS display gauge has been designed to display pressure and temperature data in real-time from a Stack TPMS system. The gauge allows you to set alarms and parameters to alert you to tyre problems while the vehicle is running on track. - Page 28 TPMS Lite Installation Guide ST542119-002 Gauge Layout Numeric display Pressure Status Temperature Status Corner Indicators Switches The gauge has been designed to provide a clear and simple view of the status of the tyres on the vehicle. There is also a numeric display which can display any of the pressures or temperatures required for more in depth information.
- Page 29 TPMS Lite Installation Guide ST542119-002 Corner Indicators In normal operation the gauge will display the status of the tyres via 4 LEDS on each “corner” of the gauge.
