ENGINE MANAGEMENT FROM
RELAY BOX
Only for secondary backup
The engine equipment includes a unit, known as
“Relay Box” which is generally fitted near the
engine room and can manage the following
functions:
• Start-up and stop.
• Selection of the control station: bridge or engine
room.
• Increasing and reducing the rotation speed.
• Self-diagnostics test (to be carried out only by
Technical Service Network personnel).
ATTENTION: It is strictly prohibited to switch the
ENGINE ROOM / BRIDGE selector when the
engine is running.
Engine start procedure
1. Move the switch (1) to the ENGINE ROOM
position, thereby enabling the adjacent
START-STOP (2) button; this operation
excludes all the functions on the instrument
panel on the dashboard.
2. Move the button (2) to the START position until
the engine starts.
3. To accelerate or decelerate: press and hold
button (2) in the START position until the
required engine speed is reached, then release
it; this operation will generate acceleration and
deceleration effects alternately. The engine
speed reached at each change will be
maintained until the next change or until the
engine is stopped.
