- With the machine turned off, set the dip-switch (A, figure 5A) which is necessary for accessing the diagnostics mode, i.e:
MBUGRF: SW1 DSW2 to ON;
- Turn the wheel balancer on;
- The diagnostics programme page “TEST SELECT” will appear on the screen. Use the arrow keys to select the test called “5 E2PROM”;
- Press the enter button to confirm the selection. The board will automatically reset the calibration parameters;
- Once the operation on the screen is completed, the OK message (green) will appear to the side of the previously selected test “5 E2PROM”;
- turn off the machine and return the dip-switch to its original position (all switches are OFF).
9. ZERO-SETTING OF THE SWINGING UNIT
If it is necessary to replace the MBUGRF main board and/or the shaft assembly, after calibrating sensitivity , the zero position of the shaft assembly
itself must be set as follows :
- mount a medium sized wheel (e.g. 5.5”X14”) on the machine with a rim preferably in steel and with a maximum residual unbalance of 10
grams per side;
Important: to properly perform the zero-setting of the swinging unit, the wheel rim must be in perfect condition, without deformations or
abrasions or dirt in the centring hole or on the plane that rests on the swinging unit. In addition, the centring accessories must be correct for
the wheel type and be clean and in perfect condition.
- clamp the wheel on the unit, keeping the valve in the 12 o'clock position;
- enter the wheel dimensions (in manual mode or automatic mode in versions with a digital sensor);
- go to the service environment as described in the “Service Programme” paragraph
- turning the unit position to encoder position notch 0;
- Remaining on this notch, hold down the Enter button (with the cursor on the “spin counter” icon) for approx. 5 seconds. A window with the
message “GRP 0” appears on the monitor;
- perform a spin;
- at the end of the spin, a window with the message “GRP 180” appears on the monitor:
- move the wheel valve to the 6 o'clock position, then keeping the unit in this position, loosen the ring nut and return the wheel valve to the 12
o'clock position;
- Perform a second spin;
- when the spin is complete, the machine will automatically prepare the service environment
- Exit the service environment by pressing the “Escape” key.
- Check that the zero-point has been set correctly for the unit by balancing the wheel. Then, move the wheel valve to the 6 o'clock position and,
keeping the unit in this position, loosen the ring nut and return the wheel valve to the 12 o'clock position;
- perform a spin. The residual unbalance obtained must be max. 3 grams per side, otherwise, repeat the procedure, paying attention to the
indicated positions and the residual unbalance of the used wheel.
