2 System Overview
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.
