Below an example for setting the parallel connection of the brake coil.
-
Standard mode:
It is possible controlling only contactor 1 and leaving contactors 2 and 3 closed.
(Fig. 13).
This protects the brake from dangerous overvoltage and noise when closing.
- Emergency mode and inspection mode:
The use of all contactors is recommended. Using only contactor no. 1 during
opening and/or closing operations may cause an unacceptable delay when clos-
ing the brake.
Typical application with brake coils in parallel configuration.
