Troubleshooting
The following is a list of errors that may occur, probable causes, and corrective action that may
eliminate the problem. If, after performing the corrective action, the problem persists, call our Technical
Support Hotline for assistance.
Our Technical Support Hotline is available for telephone assistance providing product technical support,
parts and parts information, and service agent referral.
Technical Support Hot Line: 1-800-248-2724 (U.S./Canada) or 651-385-2273.
Error 1
The controller has detected a TIMEOUT ERROR FOR THE LEFT ACCUMULATOR
MOTOR HOME SENSOR. The accumulator home encoder sensor sends an input to the
controller each time the accumulator doors cycle. It lets the controller know that the doors
opened and closed in an acceptable time. A timeout error will occur if the following
conditions are not detected. Accumulator home switch timeouts:
•
If it starts in the home area, it must leave it within 0.5 seconds.
•
Once it is clear, it will make a half turn, then pause.
•
When it has resumed from the pause, it must find the home area within 2.0 seconds.
A Timeout Error could be caused by an accumulator motor fault, broken accumulator
linkage, a disconnected or faulty accumulator encoder or a damaged encoder vane. Verify
the accumulator encoder wiring at both the board and at the encoder is secure and the vane
is in place and undamaged. Check accumulator linkage to ensure it is undamaged.

is in place and undamaged. Check accumulator linkage to ensure it is undamaged.
Error 3
The controller has detected a LARGE SHIFT IN THE TARE (EMPTY) READING FOR THE
LEFT SIDE’S SCALE INPUT. Could be caused by an obstruction of the scale or lose of
calibration. Verify the accumulator housings and flap doors are properly assembled. Check
accumulator doors to ensure there are no obstructions (i.e. fries jammed underneath).
Verify the shaft collars are not rubbing the back wall of the cabinet. If no obstruction is found
calibrate the scale. (

Error 4
The controller has detected a LARGE SHIFT IN THE TARE (EMPTY) READING FOR THE
RIGHT SIDE’S SCALE INPUT. Could be caused by an obstruction of the scale or lose of
calibration. Verify the accumulator housings and flap doors are properly assembled. Check
accumulator doors to ensure there are no obstructions (i.e. fries jammed underneath).
Verify the shaft collars are not rubbing the back wall of the cabinet. If no obstruction is found
