Service Manual
Action
Check the flag for correct operation, binding, broken parts, or
interference from the sensor cable, If incorrect, repair as necessary.
Action
Check the sensor flag for proper operation. If correct, check to make
sure the pass thru sensor cable is correctly connected to J3 on the
control board. Disconnect the pass thru sensor cable from J3 on the
control board and check the voltage at J3-3. The voltage measures
approximately +5 V dc. If incorrect, replace the control board. If
correct, check the voltage at J3-2. The voltage measures
approximately 0 V dc. If incorrect, replace the sensor assembly. If this
does not fix the problem, replace the control board.
Action
Make sure the DC motor cable connector is correctly installed at J4
on the output expander option board. If correct, disconnect J4 from
the option board and check the resistance of the motor on the cable
connector: J4-1 to J4-2 (measures between 115 and 135 ohms.) Also
check J4-1 and J4-2 to the motor case for shorts. If either the
resistance is incorrect or a short is found, replace the motor/
mechanical linkage assembly.
Note: If the DC motor is shorted, it may also be necessary to replace
the control board.
