6-20 Calibration and Adjustment
Lift Table/Clamp Bar Airflow Adjustment
Flow Control Valves (FCVs) regulate the amount of air pressure supplied to the Lift Tables or Clamp
Bars to control the speed of its up and down movement. For optimum operation, the Lift Tables or Clamp
Bars should raise and lower at the same time and at the same rate.
The location of the FCVs depends upon the device. The FCVs for Lift Tables are located on the
pneumatic hoses inside of the dispensing area, behind the Lift Tables. See Figure 6-10. The FCVs for
Clamp Bars are located on the Pneumatic Cylinders at each Conveyor station. One Clamp Bar is on the
front Conveyor Rail and one is on the rear Rail. See Figure 6-9.
? NOTE Air pressure to Stop Pins is constant and does not need to be adjusted.
CAUTION! The following procedures should only be performed by a trained
service technician.
