Attaching Weighing Platforms - KERN FTB Service Manual

8.6

Attaching weighing platforms

All analog weighing platforms can be attached to the terminals if they conform to the required specifications (see chapter
8.5). A second weighing platform can be attached to terminals equipped with the optional analog interface (OptionPac).
Compact two-scale systems can therefore be constructed using just one terminal.
8.6.1 Instructions on weighing cells
Cells with or without SENSE lines
In case the weighing platform employs a measuring cell without SENSE lines, the pins "+Ex" (Excitation) and "+Se" (Sense)
must be short-circuited at the connector, as well as pins "–Ex" and "–Se".
Cells without SENSE lines
Attaching weighing platforms with several weighing cells
Up to 4 weighing cells can be connected in parallel to a terminal. These weighing cells can be connected in the usual way
using a junction box.
The sum of the rated capacities of the individual cells corresponds to the total capacity of the weighing system. When entering
the weighing capacities in the menu-driven dialog (chapter 7.7.4), the values should be selected so that the individual cells
are not overloaded!
