Operating elements at the control station

A control station is defined as a spot from which the vessel can be controlled. At this spot there is a lever, which serves
to adjust the engine speed as well as the gear position (ahead, neutral and astern). In addition, there are buttons and
lamps, by means of which further functions can be activated or indicated.
Marex OS II offers the following control station
variants:
 A: with a control head type 240, 241, 244 or
251 with integrated buttons and lamps
 B: with a control head type 230 with
separate buttons and lamps
Both types can either be designed for a
propulsion system with only one engine or for
twin-engine propulsions. In case of twin-engine
propulsions two levers (portside and starboard)
are provided which act on the respective
propulsion.
Usually, several control stations are existent on
a vessel. In total, up to 6 mounted control
stations can be administrated by the remote
control.
The vessel is always controlled from only one,
the so-called active control station. The other
control stations are passive.
If the active control station shall be changed,
e. g. from bridge to fly bridge, a command
transfer must be initiated by pressing a button
(cf. page 19, chapter 5.2, Change of control
station).
In the following the individual devices as well as the functions of the buttons and lamps are explained closely.
4.1 Control head 240 / 241
A control head type 240 or 241 is provided with one
lever for single-engine systems or two levers for twin-
engine systems, by means of which the engine speed
and gear direction are set. In case of twin-engine
systems the left lever acts on the engine and gear on
portside, whereas the right lever acts on the engine
and gear on starboard.
In total, three detents exist for the lever movement:
 neutral: the nominal value for speed is
idle, the gear is disengaged
 detent ahead: the nominal value for speed is
idle, the gear is engaged in ahead
 detent astern: the nominal value for speed is
idle, the gear is engaged in astern
Between the detent ahead and the position full ahead
or the detent astern and the position full astern only
the engine speed is adjusted from idle to nominal
speed, the gear position does not change.
