Direct Span
Notes:
1. Direct span entry (P368) is intended for use when replacing software or
hardware, and it is not convenient to perform an initial span at that time.
2. A record of the last span count is required.

Multispan
The BW500 offers a multispan function, which allows the BW500 to be calibrated for
up to eight different feed conditions that would produce varying load characteristics.
Different feed conditions are typically related to the running of different materials or
multiple feed locations. The varying load characteristic often has a bearing on the belt
tension, and is observed especially when in close proximity to the scale. To
accommodate such scale applications, a span correction can be made by selecting
and applying the appropriate span.
Since every material has its own unique physical properties, and may load the belt
differently, a span calibration may be required for each material in order to realize
maximum accuracy.
In the case of different feeder locations, a span calibration may be required to match
each feedpoint or combination of feedpoints.
Each time one of the eight conditions is in effect, the corresponding multispan is
selected prior to putting the BW500 into the run mode. The selection is made by
either changing the multispan operation number, accessed via P365, or by external
contacts connected to the Auxiliary input, and programmed via P270.
In order to enable multispan operation, the following must be addressed.
•
connection
•
programming
•
calibration
•
operation
for example, the last valid span count
