  • Page 8: System Description

    The autopilot system can be expanded and enhanced with a selection of options and accessories. The brain in the AP25 autopilot system is the single "intelligent" autopilot computer that communicates on the proprietary Robnet2 network to establish a reliable digital communication and power distribution network between the units in the autopilot system.

If you prefer the increments to be 10° each press, proceed as follows: Select Course adjust and turn the course knob to change the setting.

  • Page 43: Auto Mode

    Other relevant settings are described under STANDBY mode in this chapter. Response The Autotune function in the AP25 is so refined that 80-85 % of the boats will need no further adjustments of the steering parameters. On some boats, however, or at particular sea conditions a fine tuning of the steering parameters may improve the performance of the autopilot.

    Operation Seastate filter OFF: Seastate filter is disabled. AUTO: Automatically reduces rudder activity and autopilot sensitivity in rough weather by an adaptive process (default). MANUAL: Manual yaw band adjust (1-10, 10 ≈ ±6°). The manual setting determines the number of degrees the vessel may deviate from the set course before any command is given to the rudder.

    Simrad AP25 Autopilot Cable connections Use only shielded cables, also for the Mains input. Signal cables should be 0.5 mm (AWG20) twisted pairs. The mains supply cable should have sufficient wire gauge; minimum 1,5 mm (AWG14). Grounding and RFI The autopilot system has excellent RFI protection. The autopilot computer should have a proper ground connection to the hull/bonding system.

  • Page 54: Cable Strain Relief

    Installation Cable strain relief Once all the cables have been run to the appropriate peripherals and connected to the autopilot computer unit they should be secured to ensure that they are not snagged or exposed to excess strain. Screw the strain relief tab to the cable exit port on the autopilot computer unit using the screws supplied and secure the cables to the tab using the wraps as shown.

  • Page 75: Compass Calibration

    Simrad AP25 Autopilot Compass calibration This function will activate the compass calibration procedure for Simrad compasses connected to Robnet2. Notes ! The RC36 Rate Compass that comes with the autopilot as standard will store the calibration and off-set data in its own memory.

  • Page 76: Compass Offset

    Configuration and Setup Compass deviation The heading from a magnetic heading sensor will normally have a deviation when compared with the actual direction of the earth’s magnetic field. This is caused by interference from the boat’s local magnetic field. The deviation will be at a minimum if the compass is placed as far as possible from any magnetic object on board.
  • Page 77 Simrad AP25 Autopilot Note ! Offset correction is always performed after the calibration. If you use COG as a reference for the offset remember it has to be a magnetic reading. The compass OFFSET feature allows you to correct for a fixed heading offset.

    Technical specifications IP protection Each part of a Simrad autopilot system has a two digits IP protection code. The IP rating is a method to classify the degree of protection against solid objects, water ingress and impact afforded by electrical equipment and enclosures. The system is recognised in most European countries and is set out in a number of British and European standards.

    Simrad AP25 Autopilot 9 GLOSSARY Apparent wind – The speed and direction from which the wind appears to blow with reference to the bow when the boat is moving (also called relative wind). Arrival alarm – An alarm signal issued by a GPS/chartplotter that indicates arrival at or at a predetermined distance from a waypoint.

  • Page 111 Simrad AP25 Autopilot True bearing – Bearing relative to true north; compass bearing corrected for compass error. True heading – Heading relative to true north (the meridian). Waypoint - A discrete point, stored in a navigator, located on the surface of the earth. Normally this point will be identified by Lat/Lon coordinates although in some systems it may be shown by T.D.'s.
