    Each of these actions can be customised to adapt the operation of the GyroPilot 3 processor to suit the user's expectations and needs.

    2. INSTALLATION 2.1. EQUIPMENT SUPPLIED The GyroPilot 3 processor is supplied in its packaging with a GyroPilot 3 bus cable 90-60-550, a GyroPilot 3 Power Input cable 90-60-553 and a Gyro3 Actuator 1X cable 90- 60-554 2.2. PROCESSOR ORIENTATION The pilot constantly checks the orientation of the case. The objective is to ensure that it is always oriented with the connectors facing down, that it has not become unhooked from its location, or is not incorrectly positioned, so as to enable steering.

  • Page 6: Configuration

    As long as confirmation is not obtained, it relies on the old orientation found, to be able to use the full functionality of the autopilot within the first seconds. 3. CONFIGURATION 3.1. CONNECTION GyroPilot 3 Actuator Junction box Rudder angle sensor Tiller...

    3.2.1. The type of rudder angle There are two types of rudder angle sensors that can be connected to the GyroPilot 3: The nke rotary sensor or an analog linear sensor. nke rotary rudder angle: The sensor should be mounted in parallel with the rudder stock or false rudder stock.
  • Page 8 Analog linear rudder angle: The GyroPilot 3 system also integrates linear rudder angles. To take such a sensor into account, it is necessary to measure the triangle of the steering system (see picture below). 5...

    This is why it is necessary to take the most accurate benchmarks as possible. 3.2.2. The type of hydraulic ram The GyroPilot 3 processor allows you to choose in the "Pilot-Maintenance" menu, the type of hydraulic ram used. 3.2.3. The type of circuit supply clutch (PWM/DC) The type of clutch used can be selected by the user in the "Pilot-Maintenance"...

    Based on all this information, it calculates the autopilot speed which is the boat speed data that the autopilot will consider. For the GyroPilot 3, the speed used by the autopilot is only a selection of the speed source (ground or surface) chosen by the skipper via a nke display.

    "Pilot" menu and then "Mode select" or from a pilot page by pressing the OK button and then "Mode select". The GyroPilot 3 processor has a total of 6 steering modes, but a display will only show the modes that can be used with the sensors available on the installation. If, for example, there is no wind speed/wind vane sensor, the wind modes will not be available.
  • Page 12 Select "Compass" in the steering mode. Steer your boat and press the Auto button to activate the GyroPilot 3. The pilot then takes the heading as a reference. The GyroPilot 3 is then activated and steers the boat. You can use the +/-1 and +/-10 keys on a PAD, a remote control or a display to adjust the set-point.

  • Page 13: Apparent Wind Mode

    4.1.4. True Wind Mode In true wind mode, the GyroPilot 3 steers the boat according to the true wind angle given by the system. Why use the True Wind mode? The true wind mode is particularly effective when sailing downwind in heavy swell: In these conditions, the GyroPilot 3 shows its potential.

  • Page 14: Gps Mode

    The SUPER modes are used in addition to the main modes. They allow the autopilot's set point to be adjusted slightly in response to a temporary phenomenon: heel variation, gust In the GyroPilot 3, only one SUPER mode can be activated at one time. There are 3 states in a SUPER mode: Status: OFF.

    o the SUPER mode has deactivated itself due to a manoeuvre or change in the main mode. Status: ON. The SUPER mode is activated • 4.2.1. Heel angle mode This mode allows you to maintain a constant heel angle. It can be activated when following a set-point in compass, apparent wind, true wind or polar mode.

    The setting range is between 0 and 3°. 4.4.12. Setting of the autopilot alarms The GyroPilot 3 processor has two configurable alarms The wind direction alarm, called "wind/heading", monitors a change in wind direction in compass mode and a heading change in wind mode.

  • Page 18: Tacking

    4.5. TACKING The GyroPilot 3 allows you to tack in any mode: compass, apparent wind, true wind or polar. Tacking or gybing is executed by a long press on the +/-10 key of a pilot control box. 4.6. The radio transmitter must first be activated in scan mode (see transmitter manual).
  • Page 19 Each time the skipper acknowledges the same alarm, the time delay doubles. Thus, an alarm with a time delay of one hour will be disabled for one hour after the first acknowledgement, two hours after the second and four hours after the third.
