2 How the system works

A sensor is installed with the valve stem in each wheel,
monitoring the pressure and temperature conditions inside
each wheel of the vehicle, and wirelessly sends the data it
collects to the receiver through two antennas. The receiver
then transfers the data by wire to the display, which is
installed on the dashboard and digitally displays the pressure
and temperature.
The system continuously analyzes the data to detect any
abnormal conditions. It will trigger different alarm settings to
report various abnormal conditions.

⑥Nut

⑦Valve cap

Before installation, make sure you identify each sensor (A, B,
C and D) respectively. Each sensor has its own electronic
module and nut. For example, you can easily distinguish the
“C” electronic module because the letter “ C” is at the
very end of the S/N. (e.g. T5200-SM5300-050816-015B-C).
Each nut also has an engraved letter that show which
sensor it belongs to.

T5200-SM5300-050816-015B-C

32

Each sensor has a corresponding ID module. With four ID

7

12

modules mounted on two sides, the display resembles a
vehicle with four wheels. The ID modules should be placed
in the same positions on the display as the corresponding
sensors are installed on the vehicle. For instance, if the
“C” sensor is installed in the left rear wheel position, then
the corresponding “C” ID module has to be placed in the
“left rear wheel” position on the display. The manufacturer
has set as the default that A, B, C and D ID modules are
placed respectively on the Left Front Wheel (LFW), Right
Front Wheel (RFW), Left Rear Wheel (LRW) and Right Rear
Wheel (RRW).

3.1.1 Use a self-locking screw ① to join
electronic module ② and valve stem ③
together. The assembly is adjustable to fit the
various angles of the rims.

3.1.2 Insert the valve stem through the rim hole
from inside. Adjust the angle between the valve
stem and the electronic module to fit the rim
properly, and then screw tight the valve stem.

3.1.3 Place plastic washer ④，metal washer
⑤ and nut ⑥ on the valve stem, and tighten
with 3.5~4.5Nm (30~40inch pounds) torque.

same way. (If the mounting head of the
tire changer is positioned at 12 o'clock,
then the valve should be at the 5
o'clock position.) Inflate the tire to
nominal pressure.

3.1.6 Apply soapsuds on the valve tip. If
no leakage is found, put on the valve
cap ⑦.Otherwise determine the reason
for the leakage and reinstall this sensor.

3.1.7 Dynamic balance the wheel
before it is put back on the vehicle.

3.2 Installation of antenna

3.2.1 Installing the antenna
Place the two antennas underneath the
rubber layers of the two 'A' posts along
the fringe of the Dashboard.

3.2.2 Place the cable of the antenna
along the front edge of the dashboard.

3.3 Installation of receiver

3.3.1 Tighten the connecting nut of
the antenna cable to the receiver only
finger tight. Do not twist the cable.

Use the same procedures to install the other three

sensors. Please install A, B, C, and D sensors on the
Left Front Wheel (LFW), Right Front Wheel (RFW), Left
Rear Wheel (LRW) and Right Rear Wheel (RRW)
respectively.

3.3.2 Remove the cover on the side of
the dashboard or below the dashboard.

receiver with the positive power cable
out of battery and the negative
ground in the circuit board of the car
respectively, the screen background
will be lighted up in blue and
displaying “000”at the four corners
in the display. Then, the joint
connecting wires should be safely
wrapped with friction tape.

3.3.4 Tie up all the cables with a strap and put in the
compartment. Then replace the dashboard cover.

3.4 Installation of display

Fix the display unit on the dashboard
with double-sided tape. Do not block
the driver's view. Pay attention to the
viewing angle of the display.

3.5 How to remove the sensor
(When removing or replacing a sensor and taking off

or changing the tire from the rim of the wheel)

3.5.1 Deflate the tire and remove the

>90

wheel weights from the rim. Push the
tire bead away from the rim. Make

sure to always set the bead breaker
at least 90 degrees from the valve stem to avoid
damaging the electronic module.

3.5.2 Firmly fix the wheel on the

turntable clamps. (If the mounting

head of the tire changer is positioned

at 12 o'clock, then the valve stem

should be at the 11 o'clock position.)

Apply lubricant to both tire bead and

rim, and then dismount the upper tire bead.

3.5.3 Use the same procedure to
dismount the lower tire bead. (If the
mounting head of the tire changer is at
the 12 o'clock position, then the valve
should also be at the 12 o'clock
position.)

4.4 Resetting the system

The system has to be reset to re-identify
the ID module in the following situations.

1) Replace the ID module;

2) Interchange the positions of the ID
modules and sensors;
Or, if the display continues to show some

RE-SET Key

incomprehensible codes or “---” , or the
data does not refresh, you may press the reset button on the
back of the display to restart.

If the 6-digit ID number shown on the display matches the
corresponding 6-digit ID number on the ID module, the
system is working Properly. Otherwise it isn't. In this case,
pull out the ID module and put it back properly. If the
problem still exists, the sensor and its ID module need to be
replaced.

Press and hold the button again for 3 seconds and the
system will resume normal working condition.

4.5 ID Module checkout

If you see one or more “---” on display,
ID module may not be properly plugged
into the display. Press and hold the
button on the display for 3 seconds and
the system will begin the checkout
process. Each ID module has a 6-digit
ID code. The display will show the first 3
digits. Press again and it will show the
last 3 digits.

Before pulling out the ID module, firmly
push the holding key on the back of the
display. Otherwise the ID module may
be damaged.

“needle plugs” on the ID module line up with the slot form
on the side of the display. Otherwise the ID module could be
damaged when plugged in by force.

1514

4.6 Changing wheel position

Each sensor and its corresponding ID module have the
same ID code. With four ID modules mounted on two sides,
the display resembles a vehicle with four wheels. The ID
modules should be placed in the same positions on the
display as the corresponding sensors are installed on the
vehicle. Therefore when you change a wheel position, the ID
module position should also be changed.

For example, if you interchanged the LFW (Left Front Wheel)
and the LRW (Left Rear Wheel), you should also
interchange the positions of the upper left ID module and the
lower left ID module.

4.7 Replace sensor

When you replace a sensor, first install the new sensor in the
wheel. Then plug the ID module came with the sensor in the
corresponding position of the display. For example, if you
replaced a sensor in the RRW (Right Rear Wheel), then you
should plug the new ID module in the lower right position of
the display.
