System Components

The system comprises the following key components:

• Steering Cylinder: The actuator that moves the rudder.
• Hydraulic Steering Pump: Provides hydraulic power for steering.
• Pump Control Module (PCM): Manages the operation of the steering pump.
• Electronic Helm: The user interface for controlling steering.
• Color Display: Provides system status, diagnostics, and setup options.
• CAN Network: Connects the various system components for communication.

A visual representation of the system shows the Steering Cylinder connected to the vessel's rudder system. The Hydraulic Steering Pump and Pump Control Module (PCM) are centrally located, with hydraulic lines running to the cylinder. The Electronic Helm and Color Display are typically located at the helm station, connected via the CAN Network to the PCM and other sensors.

Installation and Safety Information

Important Safety Precautions:

• Ensure the steering cylinder is compatible with the tiller and U.S.C.G. ratings.
• Interference with any object MUST be avoided. Failure to adhere to these warnings may result in loss of steering control, causing property damage, personal injury, and/or death.
• Maintain the main steering system in working condition, inspecting at a minimum of twice per year.
• Ensure all electrical connections are properly secured and free from corrosion.
• Refer to the installation and User's Manual for detailed information.
• Keep magnets away from steering cylinders.
