Throttle synchronization / slow vessel
mode panel
The function of the synchronization switch, gure
8, designates one of the throttles in a dual engine
installation as the master throttle. When the switch (1)
is activated each engine will respond to this master
throttle.
One parameter must be congured in EST prior to
using a secondary throttle position sensor. In the
conguration screen, Secondary Throttle Enable
Status defaults to “Disabled” and must be set to
“Enabled”. If the “Number of Synchronized Engines
Conguration” parameter is programmed to more
than one engine, this parameter is automatically set
to “Enabled”.

The slow vessel mode (2) reduces the low idle of the
engine to 600rpm. This feature allows the customer to
operate the vessel at slow speeds with all engines in
gear for manoeuvring. Slow Vessel Mode cannot be
engaged during the rst 15 seconds after the engine
has started or while the engine is in cold mode. When
slow vessel mode is engaged, the desired engine
speed will ramp down to the appropriate speed at a
xed rate. Slow vessel mode can be exited at any
time. When slow vessel mode is disengaged, the
desired engine speed will ramp up to the appropriate
speed at a xed rate.
Item (3) is a spare orice for customers use.
