7.7.4.4 Two-part group with three lines
Figure 51 shows the bus topology of a two-part group with three lines for hall calls.
Since a line structure can no longer be adhered to with more than two lines, bridges
are used here. Thus, each cable in turn forms an independent line. The bus is
terminated at each end.
NOTE !
Pay attention to the termination during commissioning. Usually only a single lift is
put into operation and the group connection is established later. In this case, the
termination must be adjusted (see individual control system).
