Autopilot | NSS Installation Manual

Autopilot setup

Verifying the autopilot connection

When an AC12N, AC42N, or SG05 is connected to the NSS system, the NSS will automatically

detect the autopilot and an Autopilot menu item will be included in the ‘Settings’ menu.

If no ‘Autopilot’ item is available in the menu, establish the connection by running the auto

select process.

The auto select process may also be used if the list of data sources needs to be updated when

a unit has been physically replaced.

If the AC12, AC42 or SG05 is later disconnected, the ‘Autopilot’ menu item will remain avail-

able, but only a few of the menu items will be available.

Commissioning the autopilot

When the autopilot installation is completed, the commissioning procedures must be per-

formed. Failure in setting up the autopilot correctly may prohibit the autopilot from function-

ing properly.

The setup of the autopilot computers (AC12N/42N) can be done in full from either an NSS/

NSE/NSO unit, IS40 Display, or from an AP24/AP28 control head. The following sections

describe how you con gure the autopilot from the NSS unit.

If you connect the NSS to an already commissioned autopilot system, you only have to do an

automatic source selection as described above before the autopilot is ready to be used.

Dockside setup

Initiating the required dockside setup is done from within the Commissioning dialog. Com-

pleted procedures are labelled with a tick.

When the autopilot computer is delivered from factory AND ANY TIME AFTER AN AUTOPILOT

RESET HAS BEEN PERFORMED, you will have to run a complete setup again.

All steps in all commissioning procedures are clearly described on-screen, and you will be

guided step by step through the process.

1. Press the ‘STBY/AUTO’ key to ensure that the autopilot is in standby mode

2. Activate the autopilot commissioning dialog as shown above

3. Select boat type

• The boat type setting is used by the system to select appropriate preset steering parameters.

It will also a ect available autopilot features.

4. Perform the rudder calibration

• Used if you have a rudder feedback unit installed. This calibration is used to ensure that the

physical rudder movement corresponds to the rudder angle displayed on the NSO unit.

VRF (Virtual Rudder Feedback) calibration

• The Virtual Feedback option enables your autopilot to steer without a conventional rudder

feedback unit. This function is designed for vessels up to 40 ft. powered by outboard or stern

drives only.

• The Virtual Feedback option will only be available when there is no feedback unit connected

at  rst time turn on, or at turn on after an autopilot reset.

 Note: Installing a feedback unit will enhance the performance of the autopilot and provide an
