x
Sensor Test and check for the failing
sensor.

Step
Actions and questions
Yes
No
1
DC motor cable connection—Make sure the DC motor
connector is correctly installed at J4 on the output
expander option board.
Is the cable installed correctly?
Go to step 2
Install the cable
correctly.
2
DC motor mechanical linkage assembly—Check the
resistance of the motor on the cable connector. Check
the resistance between J4-1 and J4-2. The resistance
measures between 115 ohms and 135 ohms.
Is the resistance correct?
Go to step 3
Replace the DC
motor
mechanical
linkage
assembly.
3
DC motor mechanical linkage assembly—Check for
continuity between J4-1 and J4-2 and the case of the
motor. It measures infinity.
Is there continuity between J4-1 or J4-2 and the case
of the motor?
Note
: If the motor is shorted from either J4-1 or J4-2
and the case of the motor, it may be necessary to
replace the output expander control board.
Replace the DC
motor
mechanical
linkage
assembly.
Go to step 4
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:
Warning:
Be careful not to short to adjacent pins on
the connector.
Are the voltages correct?
Replace the DC
motor
mechanical
linkage
assembly.
Replace the
output expander
control board.
