Symptom:Scale
reading on the Flowcon screens for one or more scales does not match the readings on the
actual scale display.
Probable Cause (in most
likely order)
 | Disconnected or broken scale
data cable at rear of computer.
|
| Broken or defective scale
data cable between the computer and the scale display.
|
| Failed scale display.
|
| Mis-programmed scale display
(usually occurs after having scales 'calibrated').
|
| Bad Flowcon board. |
Diagnostic:
| Make sure there is some
weight in the scale so that the reading is non-zero.
|
| Run the polling mode scale
test.
|
| Run the interrupt mode scale
test.
|
| (For Combo systems) run the
Combo mode scale test.
|
| When running the above
tests, swap scale connections at the white Molex connectors on rear of system to see if
the failure follows the scale
 | Be sure to reconnect scales
properly when done testing.
|
|
Fix:
| Repair the scale cable and
its connections.
|
| Replace the scale display
(if all tests fail for this scale, but other scales work correctly).
|
| Reset data transmission
parameters on the scale display:
| 4800 baud (parity and stop
bits, and simplex or duplex doesn't matter).
|
| Reading update rate should
be four readings per second minimum.
|
|
| Replace the Flowcon board
(very unlikely as the cause).
