Engine speed synchronisation (only possible with twin-engine systems)
If the special function “Engine speed synchronisation” has been enabled in the setting
units, twin-engine systems provide the possibility to synchronise the engine speeds of
both drive engines. For both drive engines to run synchronously, an engine speed feed-
back signal from a speed sensor is required for each engine.
Pressing the “Syn./Trol.” key (press once) enables the “Engine speed synchroni-
sation” function. Pressing the key again (press once) disables the function once
again.
It is only possible to enable or disable the engine speed synchronisation on the
active control stand when both command master levers are in the engine speed
range “Forwards” or during the “Warming Up” function”. Before exiting from these
areas, disable the “engine speed synchronisation”.
While the function is active, LED 4 “SYNCHRO” shows continuous light
.
.
As soon as one of the command masters leaves the engine speed range without ter-
minating the synchronisation beforehand, it is switched off automatically “Forwards”
without terminating the synchronisation beforehand, it is switched off automatically.
In this case, the LED “SYNCHRO” flashes rapidly (approx. 0.2 seconds on / 0.2 sec-
onds off) and the acoustic signal transmitter issues a continuous tone at the active
control stand (this is not a fault alarm but a warning). The second command master
must then be set into the “Neutral” position to terminate the warnings. The engine
speed of the relevant command master is kept at idling speed during this period.
While the control system is in the function “Synchronisation”, the engine speeds of both
power units can the
only be changed using the control lever of the “Master-system”. If
there is a command change to another control stand, the active function “Engine speed
synchronisation” is also taken over onto the new control stand.
Trolling
If the special function “Trolling” has been enabled in the setting units, there is the possi-
bility to use the “Syn./Trol.” key to enable the trolling mode to continuously adjust the
clutch slip.
Pressing the “Syn./Trol.” key (press once) enables the “Trolling” function. Pres-
sing again (press once) disables the function once again.
It is only possible to enable or disable the trolling function on the active control
stand when the command master lever (both command master levers in the case
twin-engine systems) is (are) in the “Neutral” position. While the function is ac-
tive, LED L8 “Trolling” shows continuous light.
If there is a command change to another control stand, the active function “Trol-
ling” is also taken over onto the new control stand.
.
In the trolling mode, the command master function changes in comparison to
the power shift mode.
The command master function in the trolling mode is described below.
