Rolls-Royce Helicon X3 G2 Double Tunnel Thruster STBD Wing Lever 000104155

Rolls-Royce Helicon X3 G2 Double Tunnel Thruster STBD Wing Lever (000104155)

The Rolls-Royce Helicon X3 G2 Double Tunnel Thruster STBD Wing Lever (Part No. 000104155) is a dual-channel marine propulsion control lever built for starboard bridge wing consoles. It commands two transverse tunnel thrusters simultaneously or independently within a Rolls-Royce Helicon X3 (HCX3) Generation 2 remote control network.

Designed around an electric shaft (EL SHAFT) architecture, this unit eliminates mechanical linkages between the bridge wing and the thruster room. The housing integrates dual redundant electronic circuits—one primary CAN-bus circuit for the Normal Control System and one hardwired analog potentiometer circuit for the independent Backup Control System—ensuring uninterrupted maneuvering capability during single-point bus or power failures.

Features

1. Dual-Thruster Simultaneous or Split Control: Operates two independent bow or stern tunnel thrusters from a single compact starboard wing station, providing precise lateral thrust vectoring during close-quarters docking.
2. Galvanically Isolated Dual-Circuit Architecture: Houses completely independent electronics for the Normal CAN-bus control loop and the hardwired Backup control loop, preventing a single fault from disabling thruster pitch/speed commands.
3. Bumpless Command Transfer: Integrated IN COMMAND push-button and LED status indicators allow operators to take or hand over thruster control between the Fore Bridge, Aft Bridge, ECR, and Port/Starboard Wings with visual alignment confirmation.
4. Weather-Resistant Bridge Wing Construction: Sealed top bezel and shaft gaiters protect internal potentiometers and hall-effect/encoder sensors against salt spray, condensation, and washdowns on exposed or semi-enclosed bridge wings.
5. Direct Audible & Visual Fault Annunciation: Built-in buzzer and backlit alarm indicator immediately alert the watch officer to lever order discrepancies, CAN bus dropouts, or potentiometer feedback limit violations.

Frequently Asked Questions

What is the difference between Rolls-Royce part 000104155 STBD Wing, Port Wing, and ECR levers?

All three stations use the same core hardware assembly (000104155 G2 Double Tunnel Thruster Electric Shaft Lever), but differ in their engraved/printed station faceplate labeling, CAN-bus node address configuration (e.g., UN30 TT vs. UN70 TT), and dimming circuit integration tailored to either an indoor Engine Control Room console or an outdoor bridge wing console.

Can this lever operate in Backup Mode if the main Helicon X3 CAN bus fails?

Yes. The lever contains two physically and electrically separated circuits. If the Normal Control CPU, power supply, or CAN fieldbus fails, switching to Backup Control routes the lever’s direct analog potentiometer signal to the thruster actuator cabinet, allowing manual thrust control without external DP or joystick interfaces.

Is the Rolls-Royce 000104155 lever compatible with older Helicon X (Gen 1) systems?

No. Part 000104155 is specifically engineered for the Helicon X3 Generation 2 (G2) architecture. Older Helicon X or first-generation X3 hardware uses different CAN protocol revisions and connector pinouts and is not drop-in compatible without a Rolls-Royce/Kongsberg retrofit kit.

How do I transfer thruster command to the Starboard Wing lever?

Match the physical position of the Starboard Wing lever to the currently active lever (typically zero/neutral position), then press the IN COMMAND push-button on the lever base. Once the system verifies signal alignment, the IN COMMAND indicator lamp illuminates steady and control transfers smoothly to the starboard wing.
