New Safety Relay

New Safety relay K3 (the same relay type used for activating the Drying System) for the drivers replaces the old problematic one.

The K3 relay has been moved to a new position, and the RL3 relay is installed into its place(see Figure 4).

New Main 3-phase Circuit Breaker

The main Circuit Breaker F1 (see green line) includes the Switch Tripped mechanism (terminals 9,10). The two phases are connected (see dashed green line) via the Emergency Switch.

When the Switch Tripped is powered, the F1 contacts are closed and the machine is connected to the power line.

When the Emergency Switch is pressed, the Switch Tripped is powered off and the F1 contacts are opened; i.e. the machine is disconnected from the power line.
