4060-xxx FRU 2 Output expander control board Action Disconnect the motor cable J4 and check the voltages at J4 on the board. Note: Use caution not to short to adjacent pins on the connector. Pin Status Voltage J4-1 (Motor Idle) +24 V dc J4-2 (Motor Idle) +24 V dc J4-5 (Motor Idle) +5 V dc J4-6 (Motor Idle) +5 V dc If any of the voltages are incorrect, replace the control board. If the voltages are correct, replace the DC motor/mechanical linkage assembly. No indication that bin x is full or no indication that bin x is near full FRU 1 Dual output bin x sensor assembly Output expander control board Action Check for correct installation of the sensor cable at J5 on the output expander control board. If either the Bin Full (F) or Bin Near Full (NF) fail the sensor test then check the voltage at J5-3 and J5-4. The voltage measures approximately +5 V dc. If the voltage is incorrect, replace the output expander control board. If correct, replace the sensor assembly. Diagnostic information 2-75
