Recorded Inventory Totals

Check the hopper’s scale calibration and verify that the hopper is

not overfilling. If the hopper is overfilling, adjust your hopper

don’t match what I’ve actually

size. If this is correct, then you are probably not accounting for

used

material scrap or other items in your process.

 

 

 

Printer did not print

Check that the printer is a SERIAL printer. If not, then you will

need to either get a SERIAL printer or purchase a SERIAL to

 

PARALLEL converter.

Problem

The feeder calibration values are moving too much.

Corrective action

Check to ensure that the weigh hopper is not touching any part of the frame and that the loadcell bracket is not touching the plastic cover of the loadcell. If these have been verified then check loadcell and replace if necessary.

Problem

Corrective action

I can’t calibrate the Scale without an error message.

This Is caused by the difference in bits not being large enough. Using the Direct Scale Readout, examine current loadcell bits with and without the calibration weight. If the bits do not change significantly, then check for pellets jamming the loadcells and check the loadcell circuit. You might have a bad loadcell.

Note: Other service problems or questions can be answered by contacting the Service Department.
