Activating BLOCK while running will work in the same way as pushing the emergency stop, but it
will also prevent the genset from starting afterwards.

The only protections that can stop the genset/interrupt the start sequence when the shutdown override input is activated,
are the digital input emergency stop (menu 3490), the alarm overspeed 2 (menu 4520) and the alarm EIC RPM overspeed
(menu 7600). All must have the fail class shut down.
