14.2 Functions
14.2.1 Start
The engine has a pneumatic starting motor controlled by a solenoid valve. The solenoid 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.
Starting 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).
14.2.1.1 Startblockings
Starting is inhibited by the following functions:
●
Turning gear engaged
● Stop lever in stop position
● Pre-lubricating pressure low
● Local engine selector switch in blocked position
●
Stop or shutdown active
●
External start blocking 1 (e.g. reduction gear oil pressure)
●
External start blocking 2 (e.g. clutch position)
●
Engine running
For restarting of a diesel generator in a blackout situation, start blocking due to low
pre-lubricating oil pressure can be suppressed for 30 min.
