OptiTire
TM
can be interrupted in its function if other devices or systems in the
vicinity are also transmitting in the area of 433 MHz. These can be radio sets,
radio remote controls (e.g. for door actuation, cranes, forklift), insufficiently
shielded electrical drives with high power or other radio transmitters. When
the OptiTire
TM
system is removed from the area of interference, the function is
guaranteed again.

Integrated components
Pressure sensor
Circuit for evaluation

Radio transmission
433 MHz signal
Transmission intervals
depends on the sensor type
the transmission frequency is increased when there are pressure changes.
Repairs
Not possible
Warning messages
With position on the vehicle
Battery
Lithium
Service life: up to 9 years
Around 6 months before the end of its service life the sensor transmits a
warning signal that the battery is exhausted
Sensor ID
An ID makes each sensor unique and ensures that the sensors are clearly
assigned to particular wheels. The sensor will "report" to ECU using this code.
This will exclude pressure signals from other vehicles to be assigned to own
system. The ID is defined when the sensor is manufactured and cannot be
changed.
This ID is imprinted on the sensor for start-up.
Only in the case of internal sensors can the ID also be read out wirelessly using
the WABCO OptiTire
TM
Handheld Tool (WABCO part number 300 200 001 0).
