According to the application of the engine and the degree of automation, apart from the basic
equipment for the local control of the engine (emergency control) further special fittings and
facilities to operate these are provided. These are not dealt with in this section.
Unless these facilities are included in the contractual supply scope of Caterpillar / MaK, then a
functional scheme and description of the functional scheme applying especially to this particular
system will be prepared and coordinated (see book C).
Direct start at the generator engine
In the scope of this initial operation we are dealing exclusively with the starting procedure on the
generator engine.
In order to ensure the functioning, it is important to know the automation degree of the system.
When alarm, safety systems and also revolution counters are switched off normally all functions are
automatically monitored, manually checked or executed.
Starting (operating panel in the gauge board)
• Switch position selector in the board on “2 = OFF”.
• Put emergency operating lever into the operation position at the operating stand or at the
control linkage.
• Engine prelubrication:
Switch on the engine prelubrication pump or auxilary pump approx. 5 min. prior to start. For
operating pressure, see A1.05.
• Set revolution speed by means of the revolution speed head on the mechanic-electric
governor to nominal setting.
• Manually start the engine at the starter solenoid or master starting valve.
Keep the starting attempt as short as possible.
• In the event of a direct engine start with electronic governors the stop must be reset parallel
to actuating the starting solenoid valve.
Attention:
Manual starting of the engine may only occur when the engine is at a total standstill!
• Switch off the prelubrication or auxiliary pump (automatically or by hand).
• In no case the starting air shut-off valve must be closed during engine operation
(A3.05.11.nn)!
