1. USING THE GYROPILOT GRAPHIC IN PILOT MODE

1.1 Presentation

We thank you for your confidence in the nke trademark, by choosing the Gyropilot Graphic.

You have just acquired a pilot command, identical to that which is fitted on sailing boats of

ocean skippers: Vendée Globe, Route du Rhum and Transat the single handed

raicing.

The nke pilot includes:

-the Gyropilot Graphic, it is the user interface. It allows to control the pilot and adjust the

settings,

-the Gyropilot 2 calculator, which is the brain of the pilot,

-the hydraulic unit or electrical unit, which provides the power to actuate the boat’s rudder,

-the sensors, which provide the information on the boat’s behaviour and external parameters.

Depending on the level of equipment of your installation, you will find: the fluxgate

compass, the speedometer, a rudder angle sensor, a masthead unit (optional for wind

mode) and the gyro sensor (integrated in the calculator).

This user and installation guide includes information that will allow you to:

-to be able to set up the Gyropilot 2 computer and the sensors,

-To become accustomed to your Gyropilot Graphic, and to master all its functions,

-carry out the installation,

-achieve optimum performances with your autopilot and your boat.

The Gyropilot Graphic is also a Multifunction display. Its graphic screen offers a wide range

of display options:

-A detailed representation of the Gyropilot 2 control parameters.

-A Multifunction that is easily displayed, for screen display of 1, 2, 3 or 4 channels.

-A pull-down menu, which indicates the settings and configurations in full.

1.2 General operation of the Gyropilot Graphic

The Gyropilot Graphic display is designed to control your pilot and your system. The

performance of the Gyropilot is excellent at any sailing speed. It will assist the helmsman

effectively, but must not be used as the primary means to navigate.

When the helmsman activates the pilot, the Gyropilot 2 computer stores the current value of

the channel concerned: magnetic heading, wind angle or GPS course. This value becomes

the reference point.

Then, the computer integrates the data transmitted by the sensors and performs rudder

corrections according to two criteria:

- the cross-track error compared to the reference point, which is provided by the fluxgate

compass (compass mode) or by the masthead unit (wind mode).

- the speed of rotation of the boat, which is provided by the gyro sensor. This rotation is caused

by the action of the rudder, the wind or the waves.

Hence the correction value is proportional to:

the cross-track error measured,

the gain value,

and inversely proportional to the speed of the boat.

CAUTION:

Never leave the helm without supervision. The helmsman must remain watchful and

attentive to the sudden events that can occur while the autopilot is operating. He must be

ready to retake control of the rudder at any moment.

1.4 First startup of the pilot

This first part of the guide explains how to use the Gyropilot Graphic, on the basis that it is

installed and initialised. If that is not the case please refer to the installation chapter of this

guide.

The Gyropilot Graphic, delivered with a factory setup configuration, will achieve a good level

of performance on the majority of boats. This setup configuration is called « initial setup», and

is saved in the Config restore menu. You can restore this initial setup at all times (see chapter

1.7.7).

Powering up or powering down your installation is done using the auxiliary switch of the electric

switchboard of your boat. Your installation must comprise two separate 12V power supplies:

one for power to the hydraulic pump and to the computer and the other for the Gyropilot

Graphic, the TOPLINE bus and the sensors. If it is not possible to have 2 batteries pack you

must set up a converter 12V/12V.

1.4.1 Procedure for the use of the Gyropilot in compass mode

-reach the open sea with your boat before engaging your pilot,

-steer your boat and maintain the heading you wish to follow : the rudder must be in line with

the axis of the boat,

-when you follow the right heading, press the auto key to engage the Gyropilot.

-the pilot then takes the current heading as reference. The Gyropilot is then engaged and

steers the boat.

-to disengage the Gyropilot, retake hold of the helm and press the stop key.

The Pilot Page below is displayed on the Gyropilot Graphic screen.

Note that when the pilot is engaged, the set point is displayed in the reference window. When

the pilot is disengaged, three dashes «---» are displayed in this window.

CAUTION:

The Auto key will engage the automatic pilot, i.e. to activate it.

The Stop key disengages the automatic pilot, i.e. to deactivate it.

Before cutting the power supply of your installation, disengage the pilot.

CAUTION: It is imperative to power up your Gyropilot computer before the TOPLINE bus.

1.4.2 Adjusting the pilot setting

If you wish to modify the heading the pilot is set to follow, you can adjust the Gyropilot

reference point at any time without disengaging the pilot. Use the keys below to adjust the

reference point

-The

key allows to decrease the reference point by 10° on port side.

-The

key allows to increase the reference point by 10° on starboard side.

-The ◄1and 1► keys allow to increase or decrease the setting by 1°.

1.4.3 Setting the pilot gain

The Gain setting is essential for good operation of the pilot. This parameter sets the reactivity of

the rudder and determines the amount of rudder movement. The gain calculation takes into

account the boat speed and is inversely proportional to that speed. Indeed, the higher the boat

speed, the lower the rudder angle.

We recommend that you set the Gain value to adapt the performances of the Gyropilot,

according to the sailing conditions and the speed of the boat.

The Gain can be set between 1and 9, here are some examples of setting :

-At close-haul, calm sea, constant wind: Gain = from 1 to 5.

-At close-haul, rough sea, variable wind: Gain = 4 to 8.

-Beam wind, rolling sea: Gain = 5 to 9.

Keys for fast access to GAIN setting

-Display the Pilot Page,

-using the ▲ and ▼ keys, set the new Gain value,

-press the

Ent

key to validate your setting : the new Gain is saved to the memory.

Useful tip: Before engaging the pilot, set the gain to 7. Steer your boat and maintain the

heading you wish to follow. Then, position the rudder in the centre, at the exact time when you

press the AUTO key. The pilot will thus take control of the rudder in the best conditions. Then,

reduce the gain to optimise the power consumption.

IMPORTANT:

The Gyropilot uses very little energy (a few tens of milliamps) when the pilot is

disengaged. Hence when you are sailing and the pilot is disengaged, it is not necessary to

cut off the power supply of the pilot to save energy.

1.5 Description of the five operating modes

The Gyropilot Graphic has five operating modes: compass mode, apparent wind mode, true

wind mode (in option), GPS mode and rudder mode. The choice of one of these five modes

allows you, depending on the sailing conditions, to make the most of the performances of the

nke pilot.

These five modes will be accessible on the Gyropilot Graphic depending on the level of your

installation:

-The compass mode requires a speedometer log sensor and a compass sensor.

-The apparent wind mode requires a speedometer log sensor, a compass sensor and an

masthead unit.

-The true wind mode requires a speedometer log sensor, a compass sensor, a masthead

unit, and a « true wind » software option.

-The GPS mode requires a speedometer log sensor, a compass sensor, as well as a GPS, or

any other instrument providing GPS NMEA frames. The latter must be connected to the

NMEA input of your nke installation.

-Rudder mode: no sensor required.

1.5.1 Selecting the pilot mode

-your pilot is disengaged,

-press the Page key to select the main menu,

-using the browser

, enter the Pilot Mode menu,

-select the Pilot mode of your choice,

-press the Ent key to validate your selection : the new pilot mode is saved to the memory.

CAUTION:

If you are sailing in wind mode and you wish to change sail, we recommend that you

switch to compass mode before performing the manoeuvre, because a sudden ship

imbalance can cause the pilot to operate abnormally for a short period of time. For safety

reasons, stay alert.
