7 - SPECIAL CALIBRATIONS AND FUNCTIONS
(See MENU ACCESS DIAGRAM )
In order to gain access to the “Reserved Calibrations and functions” it is necessary to enter a password.
Any incorrect operation within the functions described below could impair the operation of the wheel
balancing machine. Unauthorized use will cause cancellation of the warranty on the machine.
7.1 - ENABLING OF WIDTH MEASUREMENT
This function enables/disables automatic width measurement with SONAR or contact device; always
select “SONAR”.
7.2 - ENABLING OF THE DISPENSER
This function enables/disables dispenser operation.
7.3 - ENABLING OF ECCENTRICITY MEASUREMENT
Enables/disables measurement of the tyre eccentricity during an unbalance measurement spin.
7.4 CONTROL OF SERIAL OUTPUT RS232C (OPTION)
This option enables/disables the sending of the measured unbalance and phase values to serial output
RS232C.
Transmission speed
= 9600 baud
Data format = 7 bit Start
7 bit Data
1 bit Even parity
1 bit Stop
At the end of each unbalancing measuring spin, the balancing machine enables the RTS signal, then
places the "$" character on standby to be able to transmit the data; all functions remain on hold until data
transmission is enabled, at the end of which the RTS signal is reset to the inactive state.
The items of data transmitted via serial line are in ASCII format and are separated between each other
by the character (0x0d).
Sending sequence is as follows:
- 0000
- Value of correction weight, left side
- Correction phase, left side
- Value of correction weight, right side
- Correction phase, right side
The fi rst 5 zero bytes represents the start of transmission message. The correction values are expressed
in grams, in steps of .1 gram.
The phase values are expressed in degrees, in the range 0% 359
See specifi c computer board on exploded drawings.
7.5 - DRAWER UNIT
Enables/disenables management of a drawer unit with unbalance correction weights
7.6-CALIBRATIONS
When 6 is pressed from the Special Functions menu, access is gained to the Calibration menu.
7.6.1- GAUGE CALIBRATION
Select the gauge to be calibrated and follow the instructions appearing on the monitor.
N.B.:
- In the diameter gauge calibration it is highly important to position the gauge correctly as shown in fi g.8.
- In the width gauge calibration it is necessary to enter two dimensions which can be measured as
follows:
