02 INTRODUCTION Our TPMS product uses reliable integrated circuit, according diffusible silicon sensing principle and RF communication principle, which makes the product perform well, easy to install and work stably. This type product is one of the most advanced TPMS products in the world. This product belongs to Pressure-Sensor Based TPMS. The sensor is installed in tire to measure the pressure and temperature. The tire is monitored all the time and when it is under abnormal condition our product can send alarm information to driver to tell the emergency of improper pressure or temperature. Thedrivercankeepuponthetireconditionandkeepthetirein normal condition, thus the tire life can be extend. The driver can avoid increasing the braking distance and making the auto sideslip on wet road with this product Gas saving is another important benefit to customers if using this product. FOREWORD According to statistics, about 70% of all traffic accidents are caused by tire blowout, while the figure would be higher to 80%. The statistics of SAE shows that there are over 260000 accidents caused by tire blowout or leak, and about 75% tire fault is caused by low pressure or leak. US government requires developing TPMS product to reduce traffic accidents. NHTSA in US develop a project that truck, bus, car and SUV with gross weight less than 4500 Kg should be installed TPMS product to improve traffic safety. It is because long time driving under abnormal tire pressure or temperature that rubbing abrasion of tire become rapid to cause tire blowout. The aim of TPMS is to notice the driver to keep tires in correct condition when driving. Just as the figures showed below, figure B and C result in stress centralization that it makes the tire shoulder be abraded rapidly if under low pressure condition while the centre part be abraded rapidly if under high pressure. Three different inflation condition of tire A. Normal B. low pressureC high pressure 03 This product makes you drive safely. If there's any abnormal, it can send the message immediately including the value of the pressure and temperature, which make you drive reliably. The LCD, LED buzzer and keys will turn off if Key is off, but the receiver still monitors the tires, if some abnormal message is received, the information will be recorded and displayed on LCD when Key is on. , 3. Message of each tire displays in turn When Key is on and all tires are under normal condition, the message of each tire is displayed in turn every five seconds twice. Right front tire right rear tire left rearleft front . It will stay at right front tire if no warning message received. If there is a warning message andis on, the warning message is displayed, if there are 2 or more warning messages, warning messages are displayed in turn. tiretire Key OPERATIONOPERATION This product can monitor the pressure and the temperature of each tire. It will warn the driver if any tire is abnormal. a) Reading function: to check theof each tire; b) Set function: to set the standard value of pressure ,unit temperature; c) Warning function: L low power of transmitter, no signal. information of pressure and ow pressure warning, high pressure warning, leakage warning, high temperature warning,warning warning 1. Key introduction Enter key Read the information of each tire or confirm the settings. UP key: select transmitter and increase DOWN key: Set and decrease : . . Receiver operation UP key DOWN key Enter key 2. Power on The LCD shows as the following figure when power on, which means the receiver is doing self checking and all LED on. The self checking will be finished in 3 seconds and the LCD will display the information if Key is on. 0405 PSI Bar F C b) Leakage: the buzzerand yellow LED is on; the value of pressure and temperature, the tire icon of the transmitter are displayed and the icon of leaking is flashing; the buzzer will stop buzzing if any key is pressed. The warning message of each tire will be displayed in turn if more than one tire is under abnormal condition. warningturns on for 6 beeps warning c) Low pressure: the buzzerand red LED is on; the value of pressure and temperature, the tire icon of thetransmitter are displayed and the icon of low pressure alarming is flashing; the buzzer will stop buzzing if any key pressed. The warning message of each tire will be displayed in turn if more than one tire is under abnormal condition. warningturns on for 6 beeps warning is OPERATIONOPERATION 4. Displaying in turn finished: a) If some warning message is received, the warning message will be displayed b) Any key press will stop turn-by-turn displaying except UP key if there is warning message. 5. Warnings a) High pressure warning: the buzzer turns on for 6 beeps and red LED is on; the value of pressure and temperature, the tire icon of thetransmitter are displayed and the icon of high pressure is flashing; the buzzer will stop buzzing if any key is down. The warning message of each tire will be displayed in turn if more than one tire is under abnormal condition. warning 0607 d) High temperature: the buzzerand red LED is on; the value of pressure and temperature, the tire icon of the transmitter are displayed and the icon of high temperature alarmingisflashing;thebuzzerwillstopbuzzingifanykeyispressed. warningturns on for 6 beeps warning f) No signal: the buzzerand yellow LED is on; the value of pressure and temperature, the tire icon of the transmitter are displayed and the icon of no signal is flashing; the buzzer will stop buzzing if any key pressed. the warningturns on for 2 beeps warning is Note:Only if the well inflated tire icon is displayed with green LED on, warning message of each tire will be displayed in turn if more than one tire is under abnormal condition it means no warning. The warning or messages are displayed in turn if there are more than one transmitter are under abnormal condition. warning 6. Manual reading The warning message can be displayed automat…
