  • Page 55: Ap20 System Layout

    Installation Pay particular attention to the junction unit/drive unit combinations on page 58 and the chart on page 10. As many of the units are communicating on a common network (ROBNET), with identical connectors, the installation is simplified. Try to mount the units within the standard cable length supplied with each unit, if possible.
  • Page 56 Simrad AP20 Autopilot Do not try to remove the transmitter arm from the feedback unit. Note ! The unit is factory adjusted and need no further adjustment at installation than described below. As a starting point, it is desirable to set the transmitter rod to the inner limit of the outer slot if possible.

  • Page 57: Junction Unit Installation

    Installation Due to space limitations, it may be necessary to cut the length of Note ! the transmitter rod to move the RF300 closer to the rudder post. Tighten the mounting screws for both the RF300 feedback unit and the transmitter rod ball joint. Observe the RF300 while someone turns the helm wheel through the complete travel from full port to full stbd.

The CLUTCH/BYPASS voltage is automatically set to the same as the drive unit voltage. In Rudder Test, the AP20 system will automatically detect whether the drive unit is a reversible motor or solenoid operated.

Manually turn the helm to starboard until the rudder stops at maximum starboard rudder. Dockside Turn Rudder max STBD Adjust? The value shown on the display is the value read by the rudder feedback unit before any adjustment is made.

  • Page 102 Simrad AP20 Autopilot Recommended speed during Autotune varies with the type of boat, but should not exceed 10 knots. Autotune should not be performed at planing speed! For displacement boats use a speed that is approximately half the normal cruising speed (i.e. if cruising speed is 10 knots, do the Autotune at about 5 knots).

  • Page 104 Simrad AP20 Autopilot The two most important parameters that determine the performance of the automatic steering are Rudder and Counter Rudder. Rudder sets the rudder gain which is the ratio between the commanded angle and the heading error ( P-factor).

    Installation New course Correct setting of counter rudder, ideal response Autotrim standard value is 40 sec. which should work well on most boats. Rudder Limit should be kept at 20 degrees unless there is a need for more rudder when performing dockside manoeuvres. Caution ! In no event should the Rudder Limit be set to a value higher than the actual maximum rudder angle.
