Note: Before performing the following checks, run the Output Bin X Sensor Test and check for the failing sensor.
Sensor Test:
NF = Near Full (Upper part of sensor assembly)
F = Full (Lower part of sensor assembly)
P = Pass Thru Sensor

Action
Check the flag for correct operation, binding, broken parts, or
interference from the sensor cable, If incorrect, repair as necessary.
or replace the output expander option.
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 output expander option.
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 option. If correct, replace the sensor
assembly.
