MIN ADJUST RATE - ALARM CODE:56
Indicates Motor factor is too high which causes the MGF to dispense too little
material over time, causing the rate adjust limit to reach .3000. When the MGF
makes a correction, the RATE ADJ value is re-calculated to compensate for the
accumulated error. If the new RATE ADJ falls below the LBE (Lower Boundary
Error) (Defaulted to 30 = 0.30), then this alarm is triggered. Doing a prime
calibration is recommended and this will set your motor factor and rest rate adjust
to 1.000.
TROUBLESHOOTING CONTROLLER PROBLEMS
If you have problems, the more information you can provide us about what caused the problem,
the more we can do to improve our product so that these problems cannot, and do not, occur in
the future. In some cases, we may NOT be able to duplicate YOUR particular problem in our
testing facility. Describe the problem as CAREFULLY and as completely as possible to help us
locate and correct any design weakness that might be responsible for the problems you are
having.
TROUBLESHOOTING LOSS OF COLOR
1. Check that color supply is adequate.
2. Confirm that the motor is turning. Check proper connection of the motor plug.
3. Check that the drive coupling is not slipping, and is securely attached to the motor shaft.
The connecting tube between the motor coupling and the auger coupling is designed to
slip under high torque. If excessive loading has caused it to slip, it may have become
worn, or loose, or moved out of correct position.
