[c] Troubleshooting
1) Machine will not start
(i) Move dip switch no. 7 to the “OFF” position. If the machine starts up within a few
seconds, the bin control is the likely problem. If the machine does not start up,
refer to section “IV. Service Diagnosis” to verify that non-bin control related issues
are resolved.
(ii) Check to make sure shipping tape has been removed and the wires are connected
properly.
(iii) Check to make sure no obstruction prevents the lever from moving to the bin empty
position.
2) Machine will not shut off
(i) Refer to Section “IV. Service Diagnosis” to verify that non-bin control related issues
are resolved.
(ii) Dip switch no. 7 should be in the on position. If the switch is in the off position, the
controller board will not receive input from the bin control.
(iii) Move the lever to the far right.
a. If the machine does not shut off, check the resistance values of the resistor
wire harness. You should read approximately 15.8 K
Ω
between the black
terminal and the red terminal that connect to the K4 connector on the
controller board, when the lever is in the bin full position (far right). If this
reads approximately 7.9 K
Ω
, the resistors may be miswired. Switch the black
and white wires in the terminal housing or order a replacement wire harness.
b. If the preceding steps do not resolve the problem, replace the bin control
assembly.
