Troubleshooting
Please set controller to at least “5” for diagnostics.
This view of the control
assembly “upside down” is
to show you the speed pot
adjustments on the bottom
side of the controller.
Pot near the white wires LOW SPEED.
Pot near the blue wires HIGH SPEED.
Setting the low speed pot adjustment:
(small screw driver with plastic handle is needed)
Turn the speed pots clockwise to increase the speed and counterclockwise to decrease. The low speed pot should be set so
the belt (or sprocket) moves very slow at the lowest setting on the controller, just before the controller is clicked in the off
position. The high setting is set so 90 VDC is the maximum voltage to the motor, a volt meter is needed for the high speed
adjustment. The control assembly should be placed on a bench so the speed pots are up and accessible.
Caution: Do not to touch the open wires around the controller and the fuse holder.
