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.
