MAINTENANCE, TROUBLESHOOTING, AND ERROR CODES
This is a failed communication between the MP6000 scanner PCB
and the scale device. There are three issues that can cause this fault
condition:
• Circuitry on the MP6000 scanner PCB is failed.
• Internal cable between scanner PCB and the scale device is
faulty.
• Internal circuitry on the scale device is faulty.
This is a failed communication between the MP6000 PCB and the
Scale Display. There are three issues that can cause this fault
condition:
• The Scale Display configuration parameter is enabled and no
Scale Display is connected to the MP6000 scanner/scale. Refer
to the MP6000 Bar Code Programming Guide (p/n
72E-172633-xx) for scale parameters.
Display circuitry on the MP6000 PCB failed.
•
• The Scale Display cable between the MP6000 PCB and the
Scale Display is faulty, or the internal circuitry of the Scale Display
is faulty. The Scale Display and cable are a single Line
Replaceable Assembly (FRU*).
NOTE *In most applications, p/n MX201-SR00004ZZWW can be ordered
as a replacement.
This condition occurs when the scale detects constant motion on the
weighing surface for an extended duration of time. This is a latched
fault, meaning the MP6000 needs to be powered off, the problem
fixed, and the MP6000 powered back on. There are one of three
reasons for this fault condition.
The scale was improperly installed, or is mechanically bent or
a.
damaged where it cannot achieve a stable weight condition.
The scale or the platter is pressed up against a fixed object and
b.
its free motion is inhibited.
Debris is lodged under one or more of the over travel stop
c.
screws.
NOTE If this occurs, the recommendation in most cases, is to remove and
re-seat the scale. The scale should be replaced if the condition
persists.
