Module 2: operation types
Training
Schrader (GB)

Each valve has:
An antenna
for reception
+
An antenna
for emission

- Schrader (GB) (125 KHz / 315 MHz FM (FSK))
- Siemens, Beru ( Allemagne) (125 KHz / 315 ou
433 MHz)
- TRW ( USA) (125 KHz / 315 Mhz (ASK))

- Pacific valve (Asie)
- Johnson control (SAGEM)
- etc………
Details on the valves
available on the market:
After being awaked, the valve transmits its identifier and
the pressure of the wheel. Each valve is programmable
and can be sent to sleep again.
Example of information: Remaining lifespan of the
battery, date of production of the valve, moisture,
acceleration, Temperature....
Note: in general, to function the valve must be under pressure (> 500 mbar)

Training
• Each valve has its own identifying code
=> the driver knows which wheel is concerned with a
possible problem of under-inflation.
• This identifying code is also used to avoid an interference between
2 vehicles stationed one beside the other.
• Installed on the line of production, the station will transmit each
code-identifier to the calculator of the vehicle, by the intermediary
of the network machines.
Without that, the dashboard of the vehicle would indicate a "error",
because no valve would be recognized by the calculator of the vehicle.

STATION TPMS:
Technical data antenna / network
•
Frequency of activation: 125 KHz.

Range: adjustable of 20 cm at 60 cm maximum.

Cycle time : generaly 60 sec. *

Emission field: approximatively +/- 20 A/m (contact).


Reception AM/FM: 433 and/or 315 MHz
(only one installation = bi-frequency)
Tape speed of the line of assembly: until 5m/min*
* depends on type of valve and line of assembly
