2 INSTALLING THE HYDRAULIC UNIT
Read this guide entirely before starting the installation .
Read the installation manual the hydraulic linear drive manufacture.
2.1 Preparing the rudder arm
If it is not possible to install the drive unit directly to the steering quadrant, then you will
have to buy and install a rudder arm for your rudder shaft. The rudder arm can be mounted
on the rudder shaft in any direction.
Make sure that the ruder arm can freely move 35° in both directions and that there is
enough room available to mount the drive unit and rudder angle sensor as per the following
sections.
Check with your boat manufacturer for special instructions on mounting autopilots to your
rudder shaft or your quadrant
Drill a  16mm hole to mount the hydraulic linear drive axis:
- 240mm from ruder axis for pack type 60
Drill a  14mm hole to mount the hydraulic linear drive axis:
- 190mm from ruder axis pack type 40
- 170mm from ruder axis pack type 32
- 150mm from ruder axis pack type 27
Drill a  12mm hole to mount the hydraulic linear drive axis:

WARNING:
The force developed by a hydrauli
c linear drive is very strong and could result in serious
damage if impropally installed.
The linear drive and the hydraulic pump must be positioned on an horizontal plan.
Make sure that the linear drive support is positioned in the way that the
rudder arm or rudder
sector is in the same horizontal plan as the linear drive axis.
The mounting
of the linear must be very rigid and you should not hesitate to strengthen it with
a stainless steel plate strongly attached to the boat.
The rod of the cylinder is very fragile, and must not receive shocks, which could cause the rip
of the lip seal and therefore an oil leak.

2.2.3 Installation procedure
- Put the rudder to the axis
- Unscrew half the way the tip at the end of the drive rod, and pull the rod half the way out
such as the length between the axis of the linear support and the thrust axis is equal to
the rod length
- Place the linear drive at 90° of the rudder arm
- Fixed it with 4 stainless steel screws and nuts.
- Grease the thrust axis of the linear drive and fix it on the rudder arm or rudder sector
with the supplied nylstop nut.
- Adjust the rod tip on the same axis than the thrust axis and block it in position with the
counter-nut.
- Insert the thrust axis in the rod tip and block it with a lynch pin.
WARNING:
Check that the mechanical rudder stops are in use. If the l
inear drive is used as a rudder
stop, it could be irremediably damaged.

2.3 Installation of the hydraulic pump
Select a location where it is easy to access to the pump for maintaining : oil adjust, speed
setting.
Fix the pump with 4 screw and nuts  6mm, on an horizontal plan.
WARNING:
Don’t forget before start up , remove the shipping cap on the top of the oil tank
and replace it
by the evented cap supplied with the hydraulic unit.
2.4 Installation of the rudder angle sensor
2.4.1 Precautions
- The sensor arm must be able to move ± 90° UNOBSTRUCTED.
- When the rudder is centred, the sensor arm must also be centred (in relation to the axis
screw head-see below).
- Distance “A” must be equal to “B”.
- The sensor connector must be 90° to the rudder arm when the rudder is centred.
- It must be installed in a safe/dry location and away from interfering equipment (radio
receivers, compressors, speakers, generators, etc.)
- The mounting location must be rigid and with the sensor arm and the rudder arm in
the same horizontal plan.
Correct mounting Not allowed

- 9 - Gyropilot_2_um_EN_7_30
2.4.2 Installation procedure
1. Present the threaded rod in front of the rudder shaft, measure the maximum distance
where you can place the sensor, in function of the rod length. The sensor arm will have
to be able to rotate by 70° in both ways.
2. Measure precisely the distance A
3. Carefully centre the sensor so that the straight line going by the axis of the sensor arm
and the blocking nut is parallel to the rudder arm.
4. Drill a  7mm hole and mount the threaded connector arm to the rudder arm and the
sensor arm.
5. Then, cut the threaded rod such as value L = A-22mm
6. Mount the tips on the threaded rod, and block them with the counter nuts.
7. Before mounting the rod and tips on the connector arm, test manually your installation :
maintain the tips just above each connector, and move the rudder from Port to
starboard. If the parallelism is good, you can mount the tips on the connector arms.
WARNING :
When the rudder is centred, the rudder arm of the angle sensor must also be centred and
parallel to the rudder arm.
The threaded rod must always be parallel to the linear drive axis. If not, this could seriously
damage the sensor.
The A lenght of the threaded rod must be less than 360mm.

3.6 Connecting the power supply of the linear drive motor
ATTENTION:
The Gyropilot 2
computer is designed to supply the linear power supply with 12VDC or
24VDC, but the TOPLINE bus must always be supplied with 12VDC.
The supply power wires, from the computer and linear drive to the power batt
ery, must be
as short as possible.
It is necessary to protect the linear drive power supply, using a fuse or a circuit breaker on
the red wire : 30A for a 12VDC supply and 16A for a 24VDC supply.
Recommended wire section to supply the power battery to the linear drive motor.
Length from battery to the linear drive
motor, via the Gyropilot 2 computer Recommended section
3 m 2,5 mm²
5 m 4 mm²
7 m 6 mm²
10 m 10 mm²
A too low section cause heating of cable and decrease the performances of the Gyropilot.
As the electric power of the solenoid are low, it is not necessary to connect the power
supply with higher electric wires diameter.
WARNING:
To avoid drop voltage on the TOPLINE BUS, it is strongly recommended to use two Batteries :
one for the linear drive unit power and another one for the TOPLINE BUS and the instrument. If
it is not possible on your boat, use a DC/DC 12V converter to separate the
TOPLINE BUS
From the linear drive unit power.
WARNING:
After a longtime ( some months ) without drive unit activity
Suggestion : To connect the clutch directly on your battery, because at the first time after
this long time the clutch will request a big current to start and the internal fuse of the
autopilot computer will down ! To repair that, we must send back your computer in factory.

3.7 Connecting the computer to Topline bus
1. Make the computer bus cable run towards the TOPLINE terminal box of your
installation.
2. Connect the bus cable inside the terminal box :
If you reduce the length of the bus cable, strip and galvanise the wires before connecting
them inside the terminal box.

4 INITIALISATION OF THE COMPUTER
This chapter describes the initialisation of the Gyropilot 2 computer and the Gyropilot
Graphic. See also the Gyropilot Graphic user manual.
4.1 Initialisation
After installing the Gyropilot, you must initialise the whole of your pilot system. This is
required in order to perform the training of the Gyropilot computer: position the rudder at
the centre, then into limit stop on starboard side and finally into limit stop on port side, so
that the computer stores these positions of the rudder. These three rudder positions are
essential for the good operation of the cylinder of the pilot.
Follow the menu « Pilot Initialisation » of the Gyropilot Graphic which will guide you
along the procedure.
Procedure
 Using the Page key, select the Main menu page,
 then using the browser, select Configuration then Pilot initialisation,
 press the Ent key,
 the following message is displayed « This procedure will erase current settings.
Press the Ent key to start. Press the Page key to exit », press the Ent key,
the Gyropilot Graphic will guide you through the positioning of the rudder : follow the
indications :
 After performing an auto test, your pilot is initialised,
 Exit this menu by pressing the Page key.
Position the helm perfectly
in the centre then press
the Ent Key
Position the helm into
limit stop on starboard
side then press the Ent Key
Position the helm into limit
stop on port side then
press the Ent Key
WARNING :
Inadequate initialisation of the pilot can lead to premature wear of the parts, poor heading
maintenance by the pilot and excessive electrical consumption.
If you are unsure about your setting, perform the initialisation once again.

- 19 - Gyropilot_2_um_EN_7_30
4.2 First start-up of the pilot
See the Gyropilot Graphic user manual.
Note that 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.
WARNING : It is imperative that you power the autopilot breaker before the Topline
breaker. This allows the instruments system to recognise the Gyropilot
