7.7.4.2 Two-part group with a line
Figure 49 shows the bus topology of a two-part group with one line for hall calls.
Here, too, the line structure is adhered to and the bus is terminated at the ends.
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).
