11. Using a 3mm Allen key, remove the three screws that secure the belt clamp
to the bearing block and remove the belt clamp.
12. Remove the drive belt from the transport mechanism.
13. Fit the new drive belt terminating both ends at the top of the bearing block.
14. When placing the belt in place on the bearing block, ensure that any slack
is taken up without applying any tension to the belt.
15. Refit the belt clamp.
16. Refit the drag chain to the belt clamp.
17. Connect the vane stepper motor.
18. Refit the board stop vane.
19. Refit the front outroad conveyor.
20. Using a piece of wire between the pulley and the transport mechanism
extrusion, engage a forcemeter on the transport mechanism pulley on the
inroad side of the transport mechanism. Apply a horizontal force of 24kg.
21. Maintaining this force, tighten the securing nut.
22. Carry out the front conveyor alignment for the outroad conveyor, Front
Conveyor Alignment - Adjustments and Settings section of this chapter
refers.

WARNING
LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS EQUIPMENT.
ENSURE ALL ELECTRONIC COVERS AND MAIN MACHINE COVERS ARE
FITTED BEFORE OPERATING THIS EQUIPMENT.
The inroad and outroad conveyor transport belts are driven independently by
four variable speed motors. Inevitably one motor drives faster than the other
motor. It is necessary to calibrate these motors so they drive at the same speed.
Each belt motor speed is controlled by a separate speed controller module
situated on the right hand RTC rail support beam.
The belt speed is measured using a tachometer on the transport belt pulley and
adjusted using the potentiometer on the speed controller module.
Calibration
Procedure
1. In Diagnostics, select Rapid Transit Conveyor.
2. Select Toggle Inroad Belts to start the belts on the inroad conveyor.
3. Select Toggle Outroad Belts to start the belts on the outroad conveyor.

4. Using a tachometer fitted with the surface speed test wheel, positioned on
the input or output pulley, measure the speed of all four transport belts and
check that the speed is 44 - 46 metres/min.
5. If adjustment is required, using the labels attached to the cables connecting
to the motor speed controllers, identify which motor speed controller is
associated with the transport belt that needs to be adjusted.
6. Adjust the appropriate motor speed using the potentiometer situated
beneath the white plastic cover on the motor speed controller module.
7. Select Toggle Inroad Belts to stop the belts on the inroad conveyor.
8. Select Toggle Outroad Belts to stop the belts on the outroad conveyor.
9. Select Exit to leave diagnostics.
