14.2 Functions
14.2.1 Start
The engine is started by injecting compressed air directly into the cylinders. The solenoid
controlling the master starting valve can be energized either locally with the start button, or
from a remote control station. In an emergency situation it is also possible to operate the valve
manually.
Injection of starting air is blocked both pneumatically and electrically when the turning gear
is engaged. Fuel injection is blocked when the stop lever is in stop position (conventional fuel
injection).
Startblockings are handled by the system on the engine (main control module).

● Turning gear engaged
