MC 3020D Central Control Arrangement
In this scheme, a single MC 3020D is mounted next to one or more CP 3021 Expansion Panels. The operator first selects a
delegation group (or groups), then a machine (or machines). With four expansion panels, up to 80 machines can be accommo-
dated. An installation example is shown in Figure 2−91. For configuration instructions, please see page 5−159.
