07 CONTROL AND INSTRUMENTATION SYSTEM
Electrical control system
The electrical control system is centralized to
local control panel which is part of the automation
system. As the automation system used is
WECS, the emergency stop button is part of it.
The emergency stop button is connected to the
Relay Module of the automation system. When
the emergency stop button is pressed down the
Relay Module instantly shuts the engine down.
The emergency stop button is located on the front
side of the main cabinet.

Control valves for starting and slow turning
Starting and slow turning 3/2 solenoid valves
controls function of main starting valve with slow
turning. Control air is taken from the starting air
supply. The valves are electronically controlled but
manually operation is possible through a button
over the valves.
Slow turning engine function is automatically
activated when the engine has been
stopped for more than 30 minutes: the engine
makes a pair of revolutions before
starting function is activated.

Blocking valves for turning gear
The blocking valves are situated on turning
device, and are part of it. The valves are
connected to the main starting valve with slow
turning and starting air control circuits.
The blocking valves prevent slow turning and
starting of the engine in case the turning device is
engaged to flywheel.

Control air pipes for waste gate and by-pass system
The working air is directly supplied to Waste gate
valve and by-pass valve.
The control air signal to positioner of waste gate
valve is supplied from the I/P converter. The
control signal controls the movement of the valve
between closed and fully open valve position.

07 CONTROL AND INSTRUMENTATION SYSTEMS
Oil mist detection system
Oil mist detection system protects the engine
against serious damages originating from main
bearing shells or piston components (eg. bearing
shells, gudgeon pin) overheating. The
atmosphere of the crankcase is continuously
drawn out by means of a labyrinth cup and
directed through an optical opacity measuring
track. In this measuring track the opacity of the
drawn crankcase atmosphere is determined by
means of infrared light.
