Appendix D. MVS-STX Error Messages
Solution
Verify the correct amount of material was
actually moved. Recalibrate when possible
with a larger movement of material.
9. Signal Processor All Hidden
Explanation
Vessel monitoring results are not shown on
the display because all channels are hidden.
Solution
Display all hidden channels again by
disabling Hide:
A. Put the MVS in Manual Mode.
B. Press the Shift Key (Shift LED illuminated)
and then press the ‘9’ Key.
C. The display acknowledges Hide
is disabled.
10. Units Overrange
Explanation
The calculated gross or net weight exceeds
six active digits (999999).
Solutions
Note
Write down all existing system
parameters before you change Form or
Units. If you change Form or Units you
must adjust system parameters to
correspond to the new Form or Units.
A. Check Form. A Form of xxx.xx yields a
maximum value of 999.999, while a Form
of xxxxx00 yields a maximum value of
99999900. Ensure Form is consistent
with the maximum expected value.
B. Check Units. For example, a value in
tons is 2000 times greater than a value in
pounds; a value in barrels is 42 times
greater than a value in gallons. Make
sure that Units are consistent with the
maximum expected value.
C. Check the calibration. Recalibrate
if required.
11. Math Channel Overrange
ChXX
Explanation
This applies to math channels only. It
indicates one of the sensor input channels
used in the math formula is above
2,097,151 counts (if +) or 0 (if -). There will
be a corresponding Units Overrange error
message on the sensor channel.
Solution
Determine which of the sensor input channels
has the overrange problem by scrolling to
each input channel to see if the Overrange
Error message is displayed. Then, see Units
Overrange above for correcting the problem.
12. Math Channel Units Over
ChXX
Explanation
This applies to math channels only. It indicates
the calculated net or gross weight from
one or more of the sensor input channels
used in the math formula exceeds six active
digits (999999). There will be a corresponding
Units Overrange error message on the
sensor channel.
Solution
Determine which of the input channels has
the problem by scrolling to each input
channel to see which has the Units
Overrange message displayed. Then,
see Units Overrange above for correcting
the problem.
13. Math Error # or
Script Compile Error #
Explanation
These apply to math channels only. They
indicate a problem with the input equation.
Solution
See Chapter 9, MVS-STX Math Channels,
for a detailed list of math error messages
and solutions.
