4
Output expander board—disconnect the motor cable
from J4 and check the voltages at J4 on the board.
Note: All voltages are approximate values:
Connector pin Voltage, motor idle
J4-1
J4-2
J4-5
J4-6
Warning: Be careful not to short to adjacent pins on
the connector.
Are the voltages correct?

Step
Action and questions
1
Bottom pass thru sensor flag—make sure the flag is
operating correctly and is not binding, broken, and
there is no interference from the sensor cable.
Is there any problem found with the sensor flag?
2
Bottom pass thru sensor—make sure the sensor is
correctly connected to J5 on the control board.
Is the sensor connected correctly?
3
Bottom pass thru sensor voltage check 1—disconnect
the pass thru sensor cable and check the voltage at
J5-3 on the board. The voltage measures
approximately +5 V dc.
Is the voltage correct?
4
Bottom pass thru sensor voltage check 2—check the
voltage at J5-2 on the board, the voltage measures
approximately 0 V dc.
Is the voltage correct?
