|Symptom||Possible Cause||Corrective Action|
|The conveyor does not start.||The circuit breaker is tripped.||Check for a short in the motor or the cable.|
|No power from I/O PCB to the motor.||Verify voltage at I/O PCB and the motor.|
|Blown fuses (I/O-version R and earlier).||Check the fuses on the I/O PCB.|
|The conveyor motor capacitor is defective.||Inspect motor capacitor for damage.|
|Conveyor is noisy or oscillates between forward and reverse.||There is a build up of chips.||Clear excessive chips and any obstructions.|
|The conveyor belt is damaged.||Inspect conveyor belt and repair or replace.|
|The conveyor belt tension is incorrect.||Adjust the belt tension.|
|The auger is noisy or oscillates between forward and reverse. Then Alarm 9906 CHIP CONVEYOR MALFUNCTION is generated.||There is an excessive chip build-up or an obstruction.||Clear all chips and obstructions from the auger trough and chip chute.|
There is no chip build-up or obstruction and machine generates
Alarm 9906 CHIP CONVEYOR MALFUNCTION
|The auger motor is bound up.||The machine is decteting an overcurrent condition. Check the discrete input CHIP_CONVEYOR_OVERCURRENT cycles from 0 - 1 or 1 - 0 (0 means overlaod condtiion. Check the motor for burnout or binding.|
Chip Auger, Conveyor, may start without operator action, even with doors open.
|Machine has software 100.17.000.1016||Update software to 100.17.000.2030 or greater. This problem has been corrected such that the conveyor never restarts automatically. With a Classic Haas Control, the operator can restart the conveyor with the door open. NGC machines that have been updated after October 10th, 2018 will have strict door rules that makes this impossible.|
M31 is restarting conveyor timers if the conveyor is already on.
|Machine has software prior to 100.17.000.2030 and the conveyor cycle keeps restarting every time a M31 is encountered.||
Update software to 100.17.000.2030 or greater. In the new software if a conveyor cycle is already running but in the off state, a M31 will NOT restart the conveyor. The conveyor will follow the cycle it is currently in.
|Alarm 9819 CHIP CONVEYOR SHORT CIRCUIT||The auger motor start capacitor is at fault.||Inspect the auger motor start capacitor for damage.|
|Alarm 9848 CHIP CONVEYOR MOTOR DISCONNECTED||There is no power from the I/O PCB to the motor.||Verify the voltage at the I/O PCB and at the motor.|
Clear chips and obstructions. Make sure the conveyor settings are optimized for the chips that are produced.
