Rolls-Royce H1127.0101 Marine Controller 000068308

The Helicon X3 remote control system is a micro-processor-based system, controlling

the propulsion units on the vessel. The following main functions are included:

• Combinator control, allowing accurate and reliable control of the propeller pitch and

motor speed (RPM). The combinator curve optimises the pitch/speed performance to

give the best operational conditions and fuel economy.

• Pitch control, allowing accurate and reliable control of the thruster pitch.

• Speed control, allowing accurate and reliable control of the motor speed (RPM).

• Direction control, allowing accurate and reliable control of the thrust direction.

• Follow-up backup control from control levers.

Helicon X3 consists of the following main components:

• Instruments, screens, levers and Viewcon on the bridge (1).

• Electrical cabinets in the instrument room (2) and thruster room (4).

• Instruments, screens and levers in the engine control room (3).

Helicon X3 may interface several external systems (5), like Dynamic positioning

systems and Autopilots

ach thruster has its own lever. Their main functions are:

• Control of pitch, RPM and azimuth direction (dependant of application)

• In operation

• Command transfer

• Lever in command

• Back-up control

• Alarm

The control lever has integrated buttons and indication lamps for command transfer,

backup system on/off, alarm indication/buzzer and push button for reset of buzzer. The

display in the base shows set command (pitch and direction) from the lever.

The lever contains two redundant electronic circuits, one for the normal control system

and one for the backup system.

Control Panel

Independent controller that takes over if the main

controller stops. Redundant system.

Alarm indicator, see alarm screen for details.

The control panel (touch screen) is the main user interface for the operator and gives an

overview of all the thrusters on the vessel. It shows the status of the system, indicates

thruster forces, displays alarms, and shows selected modes. The flat button on the top of

the screen is for dimming the illumination of the LCD display.

The screen is divided in two areas: a menu area in the left part of the screen, and a bigger

command area to the right. The menu buttons to the left selects the content of the

command area.

There is one command page for each thruster, in addition to one system overview page

and one alarm page. The overview page shows the most essential information for all

thrusters, but to activate functions or to view all available information for a thruster, the

particular thrusters’ page must be selected.

The graphical design is based on the following principles:

• All functions pages are only one click away

• Large and simple buttons which are easy to read.

• Same design theme for all clickable objects.

• To avoid unintentional activation of functions, all function activation buttons require

press on the accept button to proceed.
