    Issue 1.0 16/12/99 AP12R AND AP14R POWERPILOT The AP12R and AP14R inboard autopilots combine highly sophisticated electronics with advanced software and powerful drives to provide accurate and reliable steering performance under a variety of different conditions with minimal current consumption. AP12R - is suitable for push-pull cable steered power boats up to 9m (30 ft) in length with a dashboard mounted control head ((SFC12).

  • Page 6 Issue 1.0 16/12/99 CALIBRATING THE AP12R AND AP14R Excerpts from AP12 operation manual - Parameter Adjustment The AP12 uses highly advanced steering software, which constantly assesses how the boat is being affected by the sea conditions. By adjusting its own performance, the pilot is able to maintain the most accurate course for these conditions, just as a human pilot would.
  • Page 7 Issue 1.0 16/12/99 Excerpts from AP12 operation manual ctd - 6.2 Compass Orientation The SHS12 compass can be mounted pointing four different ways - 0¼, 90¼, 180¼ or 270¼ to the bow (Fig 6.1). ¥ The factory preset is 0¼ (pointing forward). If the compass is mounted pointing any other way, this must be programmed in before using the pilot.
  • Page 8 Issue 1.0 16/12/99 Excerpts from AP12 operation manual ctd - 6.4 Seatrial / Compass Calibration Before using the AP12, the compass must be calibrated to compensate for any magnetic deviation caused by ferrous or magnetic objects surrounding it on the boat, such as cockpit speakers etc.
  • Page 9 Issue 1.0 16/12/99 Excerpts from AP14 operation manual - Parameter Adjustment The AP14 uses highly advanced steering soft- ware, which constantly assesses how the boat is being affected by the sea conditions. By adjust- ing its own performance, the pilot is able to maintain the most accurate course for these con- ditions, just as a human pilot would.
  • Page 10 Issue 1.0 16/12/99 Excerpts from AP14 operation manual ctd - 3.2 Seastate In a rough sea, more heading errors will be detected by the pilot as the heavy seas yaw the boat back and forth. The pilot would normally be overworked trying to correct every error, causing unnecessary strain on the unit and excessive drain on the batteries.

  • Page 22 Issue 1.0 16/12/99 CIRCUIT DESCRIPTIONS SRD12 PCB Assembly Introduction. The SRD12 is the heart of the Rotary Powerpilot and all other units are linked to the SRD12. It decodes the information from the heading sender and calcu- lates the heading, acts upon user commands sent from the control unit, detects drive gearbox clutch engagement, reads the Hall Effect quadrature feedback and controls the gearbox motor drive.
  • Page 23 Issue 1.0 16/12/99 Motor Drive. Drive signals are generated by the microprocessor and out- put from ports P1.6 and P1.7, the lines being LOW for no drive and switch- ing to HIGH to provide drive. These outputs control IC9 and IC10 used as comparators set at threshold levels of +4V and +1V produced by the resis- tor network R43, R44 and R45.
  • Page 24 Issue 1.0 16/12/99 Switches. Microprocessor ports P1.0 - P1.4 are connected to switches S1 - S5 and are normally high. When a switch is pressed the relevant line is pulled low and the microprocessor actions a specific task. Bus Circuitry. The Rotary Powerpilot system is interconnected via a single line Rx / Tx data bus.
  • Page 25 Issue 1.0 16/12/99 SHC14 PCB Assembly Introduction The Remote Control Unit provides the same facilities as the fixed control unit with additional options of: manual control of sea state, alarm set and response speed, dodge facility, compass read-out and rudder position indication. The circuit diagram for the PCB is given in Drawing No.
