10.0 USER CALIBRATION
The VPI System II Balancer features a calibration verifi-
cation program which requires only a few minutes to
complete. Perform this procedure to verify calibration
when the balancer has been moved, disturbed, or when-
ever accuracy is questioned. If the calibration process
fails a service technian shouild be dispatched to perform
a complete calibration.
Follow these 3 simple steps:
1. Activate Calibration.
Press the F Button (Figure 38) then roll the shaft until
the display reads "F" “14”.
• Once F14 activates, the display will read
"CAL" " GAN" for one second.
• The display will then read "SPN" " 1 ".
2. Spin bare shaft
Lower the wheel guard or press enter to spin the shaft.
See Figure 39
• Displays "CAL" " 1 " as the machine is collecting
data and performing calculations. After taking data,
the shaft is automatically braked to a stopped.
• The display will read "SPN" " 2".
3. Spin shaft with calibration slug on the left side.
Mount calibration slug to inside edge of shaft mounting
plate as shown in Figure 40.
• Lower the wheel guard or press enter to spin the shaft
with slug.
• Displays "CAL" " 2" as the balancer is doing its
calculations. When complete, the shaft is automati-
cally braked to a stop.
• The display will read "CAL" "FIN " when the calibra-
tion is FINe.
• If for some reason the calibration detected an error,
the display will read: "Err""C__" after the shaft brakes.
NOTE: THE BALANCER WILL NOT FUNCTION UN-
TIL A VALID CALIBRATION HAS BEEN PERFORMED.
AN ERROR MESSAGE WILL BE DISPLAYED IN THE
EVENT PROBLEMS OCCUR DURING THE CALIBRA-
TION PROCESS. IF AN ERROR OCCURS CALL AN
AUTHORIZED SERVICE REPRESENTATIVE.
