
Set Wheel ID

Learn Wheel ID
This menu allows learning new wheel sensors
ID. The user can learn only one wheel, several
wheels or all wheels of the vehicle. The
sequence automatically jumps to the next wheel
such that a user can initiate all wheels without
having to come back to the display between
each wheel.
The display uses a pressure change as the
criteria to recognize which wheel sensor the
operator wants to get assigned to a given
location. The amount of pressure change
required is established at 2 PSI.
A pressure change of about 3 PSI is needed to
wake up a sensor and then an extra amount of
pressure change of 2 PSI is needed to trigger
the display. The operator has to create a
pressure change by at least 6 PSI and then wait
for the display to recognize the pressure
change. The wait time correspond to the sensor
sampling rate.
When entering the menu, the axle 1, wheel 1 is
selected by default as a starting point for the
learning. The user can select another axle with
+/- , move the cursor to the wheel number with
the right arrow and select another wheel with the
+/- or move the cursor down to the start learning
button.
After the start learning button is selected, the
display stores the first transmission it gets from
each sensor ID into the “initial pressure” for that
sensor ID. Then it compares each subsequent
pressures received for that sensor ID with the
initial one and when the comparison shows a
delta pressure exceeding the defined level
required, this sensor ID is assigned to the
selected tire location.
Once a wheel ID has been assigned, the display
increments the number of wheels done and it
moves to the next axle/wheel in the sequence
waiting for another sensor to come up with a
pressure change. Within one learning session,
the display remembers which sensor has been
assigned and it will not assign it twice.
The sequence increments the display of the
next wheel on the same axle counting wheels
from left to right and then moves to the next axle
counting axles from front to rear.
It activates the next wheel parameter each time
a wheel is done. This setting is integrated with
the vehicle electronic, activating an audible
signal on the vehicle, thus providing a feedback
to the user that he can move on to the next
wheel.
The spare Tire can be done by selecting the
axle/wheel “spare” which is internally encoded to
15:1.
