Online Calibration - Siemens Milltronics BW500 Operating Lnstructions

When the material to be run on the belt changes, the multispan is changed to the
corresponding span. This is completed either by changing the span value entered in P365,
or by closing the appropriate contacts connected to the programmed Auxiliary inputs.

It may be required to reset or note the totalizer value, as the process materials being
conveyed change. Refer to
Linearization applies concurrently to spans.

Online Calibration

The Online Calibration feature may be used to routinely check, and if necessary adjust,
the Span calibration in RUN mode, without interrupting the material flow or process.

Install a weigh bin, (bin or silo equipped to
provide a 4 to 20 mA output proportional
to weight), preceding the material infeed.
Connect the weigh bin to one of the mA
inputs on the optional mA I/O board of the
BW500: either mA input 1, terminals 5 and
6; or mA input 2, terminals 7 and 8.
Install a material feed control device,
preceding the weigh bin.
