Introduction

NAC-2 and NAC-3 autopilot computers

The NAC-2 and NAC-3 autopilot computers contain the electronics

needed to operate a hydraulic steering pump or mechanical drive

unit, while also interfacing with rudder feedback units and NMEA

2000 devices.

The NAC-2 is designed for boats up to 10 metres (33 feet) in length

and is suitable for low-current pumps, mechanical drive units, or

solenoid valves (8 amps continuous/16 amps peak).

The NAC-3 is designed for boats 10 metres (33 feet) or greater in

length and is rated to operate high-current pumps, mechanical

drive units, and solenoid valves (30 amps continuous/50 amps

peak).

Autopilot controllers

The NAC-2 and NAC-3 autopilot computers can be controlled by

various Simrad and B&G control units. This can be dedicated

autopilot controllers (e.g. AP44), Multifunction displays (MFDs) and

autopilot remote controllers (e.g. OP12) used in combination with

instrument systems, or any combination of the above.

Autopilot functions

NAC-2 and NAC-3 include a large range of functions, but not all

autopilot controllers have access to all options. E.g. autopilot

systems including only an autopilot remote controller (without

display unit) do not have access to turn patterns.

The user interface

The autopilot functions are presented slightly different on the

different displays.

This manual shows screen examples from both MFDs and AP44.

Autopilot computer setup

When the autopilot installation is completed, the setup of the

autopilot computer must be performed. Failure in setting up the

autopilot correctly may prohibit the autopilot from functioning

properly.

Introduction | NAC-2/NAC-3 Commissioning Manual 7

The setup of the autopilot computer is divided in three main steps:

•Installation settings

- Including dockside and seatrial commissioning. See "Dockside

setup" on page 10 and "Seatrial" on page 16

•User adjustment of autopilot settings

- Manual fine-tuning for various operational conditions and user

preferences. See "Usersettings" on page 23

ÚNote: The Installation settings can only be accessed when the

autopilot is in Standby mode. Some systems require a

dedicated physical standby key to perform installation

procedures. This key can be a key on the autopilot controller, on

an autopilot remote controller, or it can be a separate standby

key.

Warning: When the autopilot is delivered from

factory and any time after an autopilot reset has been

performed, the installation settings are all reset to

factory preset (default) values. A notification will be

displayed, and a complete setup has to be made.

Failure to do so correctly may prohibit the autopilot

from functioning properly!

Dockside setup

Data source selection

Before commencing with autopilot computer setup the data

sources must be available and configured.

Data sources selection is required on initial start-up of the system, if

any part of the network has been changed or replaced, or if an

alternative source is made available for a given data type and this

source has not been selected automatically.

You can let the system automatically select your sources, or set up

each source manually. Refer to documentation for the autopilot

controller or for the display unit for details about how to perform

the data source selection.

Boat characteristics

Boat type

Affects steering parameters as well as available autopilot features.

The following options are available:

•Sail

•Displacement

•Planing

ÚNote: If the boat type is set to Sail, Virtual Rudder Feedback is

not available.

Boat length

Used by the autopilot system to calculate steering parameters.

Cruising speed

Used if no speed info is available. It is used by the autopilot system

to calculate steering parameters.

Drive configuration

The drive configuration controls how the autopilot computer

operates the steering system.

Refer to your drive unit documentation for relevant specifications.
