3-1 Installation sequence
Warning Correct installation is critical to the
performance of the unit. It is vital to read this
manual and the documentation that comes with
the other parts before starting installation.
Warning
The G-PILOT main unit is not waterproof.
Mount the unit in a dry place.
The G-PILOT display unit is waterproof
from the front. Protect the rear of the unit
from water, or else water might enter the
breathing hole and damage the unit. The
warranty does not cover damage caused
by moisture or water entering the back of
the unit.
The compass, gyro and rudder feedback
unit are completely waterproof.
Warning Ensure that any holes that you cut
will not weaken the boat’s structure. If in doubt,
consult a qualifi ed boat builder.
7 Install the gyro (see section 3-7).
8 Install the display unit and any other
marine instruments that will be used with
the G-PILOT 3100 (see section 3-8).
9 Carry out the dockside setup (see
section 4).
10 Carry out the sea trials (see section 5).
If you are unsure where a part should be
installed, mount and wire the part temporarily,
without cutting holes in the boat. After the sea
trials have been completed, install and wire
the part permanently.
2-2 Other parts required
Power supply: The G-PILOT 3100 requires
two power supplies, both nominally 12 V DC:
A heavy duty supply for the steering drive
A light duty supply for the G-PILOT 3100
electronics and display unit; this supply
also powers any additional display units
and other instruments.
The power supplies require one or two
switches and fuses or circuit breakers (see
section 3-4).
Steering drive: The G-PILOT 3100 can power
a hydraulic pump, constantly running pump set,
hydraulic linear drive or mechanical drive rated
at 12 V DC and up to 20 A.
Rudder linkage: To link rudder to rudder
feedback unit (see section 3-5).
For wiring, see Select Wire Table in section
3-4-2.
External beepers or lights (optional ): The
external output is switched to ground, 30 V DC
and 250 mA maximum. If the beepers and lights
require more than 250 mA total, fi t a relay.
Other marine instruments (optional): Wind,
speed or GPS instruments can be connected
(see section 1-2).
Other parts: For systems of several
instruments, wiring and connectors are
required. Navman junction boxes can simplify
wiring several Navman instruments together
(see section 1-2 or the NavBus Installation
and Operation Manual).
Coupling connectors and 10 m (33 ft)
extension cables are available to extend the
rudder feedback unit, compass or gyro cables.
Do not fi t more than one extension cable to
each unit.
