CALIBRATIONS

Board Transport

Belt Speed

The front and rear board transport belts are driven independently by two

variable speed motors. Inevitably one motor drives faster than the other motor.

It is necessary to calibrate these motors so that they drive at the same speed.

Feeder motor speed is measured using a tachometer on the input or output

pulley and adjusted by a potentiometer control on each motor.

Calibration

Procedure

1. Remove the right hand side safety cover to gain access to the transport belt

motors.

2. Select Maintenance.

3. Select Diagnostics.

4. Use Next or Previous to highlight Rail System.

5. Select Select Module.
