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.
To enable multispan operation, the following must be addressed.
• connections
• programming
• calibration
• operation
