The power assisted steering system has been designed to make steering easier during navigation and to improve the safety conditions of the system.
The rudder wheel is electronically connected to an electronic control unit that controls the operation of the hydraulic control unit (2) consisting of two pumps driven by electric motors, a tank, a distribution block, and a block of solenoid valves that control the actuators that move the rudders.
The electronic control unit also acts as an interface for the autopilot.
Above the hydraulic pistons (1), there are anti-shock protection valves
Non-return valves are installed along the circuits to prevent backflow of the operating fluid. It is possible to check the insufficiency of the oil level in the electrohydraulic control unit tank through an optical indicator.
The main system can operate in three different conditions: MANUAL, AUTOMATIC, and EMERGENCY.
To pass from one condition to another, use the selector on the electronic control unit.
Automatic Drive
The control unit must be powered. By turning the steering wheel or using the automatic pilot, a signal is generated which, received by the electronic control unit, controls the operation of the electro-hydraulic control unit, which moves the pistons and consequently the rudders.
Manual drive
The electronic control unit must be powered. Use the control buttons on the electronic control unit to control the operation of the electro-hydraulic control unit.
Emergency drive
The electronic control unit must be switched off.
For further information on use and maintenance, please refer to the manufacturer’s manual.
