Conveyor Belt Replacement
1. Disconnect, lockout and tag the power supply.
2. Use a 3 mm hex key to remove the dust cover plate. The dust cover plate is near the
conveyor motor on the inside of the conveyor.
3. Use your hands to remove the old conveyor belt from the pulley wheels.
4. Install the new conveyor belt. Put the belt on the pulley wheels farthest from the
motor first.
Note: Make sure that there are no twists in the belt.
5. Put the belt around the large pulley wheel, then around the remaining wheels.
6. Use your hands to turn the pulley wheels several turns by hand to make sure the belt
is correctly installed.
7. Use a 3 mm hex key to install the dust cover plate.
Conveyor Speed
The conveyor speed is controlled by increasing or decreasing the line voltage to the stepper
driver with a potentiometer (R4). To adjust the conveyor speed, do the procedure below:
1. Open the enclosure access door.
2. In the enclosure, find the speed control potentiometer R4 in the top right corner.
3. Cause the upstream sensor to operate the conveyors.
4. Use a small flat blade screwdriver and turn the screw clockwise to decrease conveyor
speed, or counterclockwise to increase conveyor speed.
5. The factory setting for the conveyor speed is 80 ft/min. To go back to the factory
setting, do the steps above and adjust the speed until the voltage across the
terminals on the potentiometer R4 is 8 volts.
