7.3.3.1 - To check the encoder
When the spindle is rotated:
- the angular position “POS” should vary from 0 to 128;
- the wording “UP” should appear when rotated clockwise and “DOWN” when rotated in the opposite direction.

Check for correct
operation of the
distance gauge; the
number increases
when the gauge is
pulled out.
Check of the eccentri-
city sonar (option): the
number decreases when
a surface is approached
to the sonar
Check encoder
In the event of failure or faulty operation of the wheel balancing machine, notify the Technical Service of
all the parameters displayed.
7.4 - RS232C serial port management (option)
Enables/disenables transmission on the RS232C serial port of unbalanced values and measured stages.
Transmission speed =
9600 baud
Data format = 1 bit Start
7 bit data
1 bit Even parity
1 bit Stop
At the end of each unbalanced measurement run, the balancing machine activates the RTS signal and then waits
for the “$” character to begin data transmission; all functions are blocked until transmission is enabled, at the end of
which the RTS signal returns to the standby state.
Data transmitted on the serial line are in ASCII format and separated by the character <cr> (0x0d).
The send sequence is:
- 00000 <cr>
- Value of correction weight on left side <cr>
- Left side correction stage <cr>
- Value of correction weight on right side <cr>
- right side correction stage <cr>
The fi rst 5 zero-set bytes are the transmission start message (handshake). The correction values are expressed in gr
in steps of 1 gr.
The stage values are expressed in degrees in the range 0 % 359.
