    Issue 1.0 04/01/00 AP12R AND AP14H POWERPILOT The AP12H and AP14H 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. AP12H - is suitable for hydraulically steered power boats with a ram capacity of up to 250cc (15 cu in ) with a dashboard mounted control head ((SFC12).

  • Page 6 Issue 1.0 04/01/00 CALIBRATING THE AP12H AND AP14H Excerpts from the 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 04/01/00 Excerpts from the 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.

If this light sequence is not shown, repeat step 1, holding the but- tons down firmly. 3. Disconnect the SLF12 rod from the ram and pull it fully from the feedback body (the rod is not physically attached to the SLF12 and can be removed easily).
  • Page 9 Issue 1.0 04/01/00 Excerpts from the 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 10 Issue 1.0 04/01/00 Excerpts from the 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 11 Issue 1.0 04/01/00 Excerpts from the 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 25 Issue 1.0 04/01/00 CIRCUIT DESCRIPTIONS SCP12 PCB Assembly Introduction. The SCP12 is the heart of the Powerpilot and all other units are linked to it. It decodes the information from the heading sender and calculates the heading, acts upon user commands sent from the control unit, reads the rudder position from the linear feedback unit and controls the drive unit.
  • Page 26 Issue 1.0 04/01/00 is maintained by the microprocessor which provides precision analogue to digital conversion of the feedback signal. Motor Drive. Drive signals are generated by the microprocessor and out- put from ports P1.6 and P1.7, the lines being HIGH for no drive and switch- ing to LOW to provide drive.
  • Page 27 Issue 1.0 04/01/00 SFC12 PCB Assembly Introduction. The Control Unit SFC12 acts as the interface between the Powerpilot and the user via switches, LEDs and a buzzer to facilitate a 2 way flow of information. The circuit diagram for the PCB is given in Drawing No. E02882. Supply and Regulation.
  • Page 28 Issue 1.0 04/01/00 Microprocessor and Reset. Integrated Circuit IC2 is an integrated reset generator for the microprocessor which produces a reset high pulse of approximately 50mS duration at switch on and whenever a 5v supply failure occurs. The microprocessor IC4 either controls or receives data from the remainder of the circuitry as follows: Bus Circuitry.
