Fig. 2/4 Circuit diagram for motor-charged operation mechanism
Note:
1) For DC 24V, 30V, 48V, 60V, 110V, 125V, 220V, 240V; AC 110V, 220V,
240V
2) Spring in the diagram is discharged. Standard configurations and
options available for VD4 are contained in the diagram. Also see
relative catalogues and order forms for all possible configuration.
3) Releases and blocking magnets are fundamentally wired with rectifiers
(e.g. magnet holder 45 with integrated rectifiers V1, V2, V3 and V9).
Rectifiers function as free-wheeling diodes with DC supply.
