5 - HELM STATIONS 124
By shifting same lever further, the engine’s rpm increase proportionally to
the shifting range.
Throttle detents
Indicator Lever position
A Full speed astern
B Astern detent (idle astern)
C Neutral detent
D Ahead detent (idle ahead)
E Full speed ahead
CAUTION
The idle detent (central position in relation to throttles shifting) is 10°
ahead. The shifting degrees are measured according to this position, not
to vertical position of the throttles.
For further information, see the Manufacturer’s Manual.
Taking control phases
Set levers of throttle to idle position. The station cannot take control with
throttles set to other positions. You hear the acoustic sequence of initial-
ization.
Press CONTROL/SET near the station. The CONTROL LEDS are
steadily green to indicate that the station is taking control and that the
operator is sending the idle run control. The acoustic signal is squelched
in all stations.
WARNING
The next shifting of the handle will engage the speed.
Start the engine while sending the idle run control. If the levers of the
throttle are not set to idle run, the interlocking start switch will prevent
engine start.
Shift the levers on the forward or backward retainer. The transmission
starts and CONTROL LEDS are steadily red to indicate that the station
has taken control and that the operator is sending the forward or back-
ward run control.
CAUTION
Only one helm station can be enabled at a time.
Basic operation
The throttle has three detents: astern, idle and ahead.
With levers positioned on idle detent, the system sends idle run and mini-
mum rpm control to the engines.
By shifting one lever forwards or backwards by 15°, the forward or reverse
clutch engages. The engine holds the minimum rpm.
