Option Control Board Check the voltages at J1 on the high
capacity system board. The voltage
measures as follows:
static (motor connected)
J1-1 (Orange) +24 V dc
J1-2 (Yellow) +24 V dc
J1-3 (Green) +24 V dc
J1-4 (White) +24 V dc
motor running
J1-1 (Orange) approxi12 V dc
J1-2 (Yellow) approxi12 V dc
J1-3 (Green) approxi12 V d
J1-4 (White) approxi12 V dc
If any of the voltages are incorrect,
disconnect the motor and measure the
resistance between pin J1-1 to J1-3 and J1-
2 and J1-4. The resistance measures
between 10 and 15 ohms. If incorrect,
replace the motor. If correct, replace the
high capacity feeder control board.
