section (MSK - monitor version ONLY) and MCM inherent to the motor control board. In the DISPLAY version, these versions are displayed in function 93; - the presence of the threshold of 1 gram for the unbalance values shown. During normal working, when the “gr x 1” unbalance visualisation mode is selected, the first gram of unbalance is not shown. In this condition, the message “1 OFF” is highlighted in the appropriate window. If, on the other hand, you wish to visualise the first gram of unbalance as well, you must select the icon. In the DISPLAY version, the thresholds and rounding-offs are displayed in function 91 In this condition, the message “1 ON” is highlighted in the appropriate window. In this condition, the sensitivity of the machine is also intensified so as to calculate and visualise the unbalance values with the greatest precision possible. This characteristic allows you: to visualise the unbalance values with the maximum precision allowed, so you can balance a wheel perfectly and then carry out further checks on it. The technical assistance staff must always work with this condition. - The presence of the rounding-off (to one inch) of the values obtained with the automatic sensor. When the rounding-off is activated, the message “ON” is shown in the appropriate window. If you wish to visualise the diameters acquired with the precision of a tenth of an inch, it is necessary to select the icon. The message “OFF” appears on the display, indicating the setting of this new condition. This function allows you: to check with the maximum precision (a tenth of an inch) the match between the values obtained with the sensor and the nominal values of the wheels. - The current value of the angular position transducer of the wheel (encoder), its variation interval, and two numerical values corresponding to the number of impulses counted by the encoder during a spin and the expected value for this count (384). In the DISPLAY version, this value is displayed in function 97 These data allow to: to easily check the efficiency of the encoder. In particular, that the value of the encoder is continuously updated within the interval 0 - 511
