As compared to the AP3000, the software part of the AP4000 has been upgraded significantly. Up to five network control panels have been added to functionality. The use of only one ‘Sensitivity’ parameter for fine-tuning system performance covers all known yawing, steering and counter rudder settings of the autopilots of other brands.
The AP4000 has built-in ‘Heading Monitor System’ (HMS) functionality, which makes it possible to receive and monitor the data coming from two heading data sources continuously (gyro+gyro, gyro+magnetic compass, gyro+fluxgate etc.).
Several speed sources can also be used during operation (GPS, waterspeed log or bottom tracking log).
The AP4000’s fully self-adjusting ‘Auto Tune’ algorithm allows it to easily adapt the autopilot performance to the hydrodynamic parameters of any vessel, irrespective of its displacement and dimensions. This makes it possible to use the AP4000 onboard any commercial or leisure vessel with a single rudder, linked rudder, independent rudder or stern azimuth Z-drives configuration.
AP4000 steering gear interfaces:
Solenoid valves, 24V DC (up to 3A load current)
Proportional valves – 0…10 V, ±10V or 4…20mA control signal
Proportional rudder control (steering gears with follow-up steering control system) – 0…10 V, ±10V or 4…20mA control signal
Second gyro or magnetic compass
