Instruction Manual
This manual is intended as a reference guide for operating and
correctly installing the AP16 autopilot in a Volvo Penta IPS
system.
Great care has been paid to simplify operation and set-up of the
Simrad AP16. Set-up is significantly simplified when the autopilot
is interfaced to the Volvo system. However, an autopilot is a
complex electronic system which is affected by sea conditions,
speed of the vessel, hull shape and size, and the autopilot must be
operated with this in mind.
Please take time to read this manual to get a thorough
understanding of the operation and system components and their
relationship to a complete AP16 autopilot system.
Other documentation material that is included in this manual is a
warranty card. This must be filled out by the authorized dealer that
performed the installation and mailed in to activate the warranty.

1SYSTEM DESCRIPTION
1.1 General
Congratulations on the purchase of your new Simrad AP16
autopilot system designed for the Volvo Penta IPS system and
thank you for selecting what we feel is the most advanced
autopilot system available on the market today.
Simrad manufactures a complete range of autopilots for all types
of vessels, from recreational boats to merchant marine vessels.
The company's involvement in autopilots began in 1953 with
equipment for the North Sea fishing fleet under the brand name
Robertson. Professional mariners around the world acknowledge
that the Robertson and Simrad brand names are synonymous
with the absolute best in autopilot technology.
Automatic steering of boats equipped with a Volvo Penta IPS
system represents a new step forward in autopilot technology from
Simrad. Interfacing and steering algorithms have been developed
in close cooperation with Volvo to obtain the best possible
autopilot performance. The way the autopilot integrates with the
IPS control system is described in the IPS user manual from
Volvo.
The autopilot system can be expanded and enhanced with a
selection of options and accessories.
The brain in the AP16 autopilot system is the single "intelligent"
autopilot computer that communicates on the proprietary
Robnet2 network to establish a reliable digital communication
and power distribution network between the units in the
autopilot system.
The AP16 autopilot is also equipped with the SimNet data and
control network. SimNet provides high speed data transfer and
control of Simrad products integrated in a total steering and
navigation system.
1.2 How to use this manual
This manual is intended as a reference guide for operating,
installing and maintaining the Simrad AP16 autopilot. Great care
has been paid to simplify operation and set-up of the AP16.

multistation system the command can easily be transferred from
one unit to another. AP16 units not in control will display the
icon.
The AP16 system is capable of the following primary steering
modes: STBY (power steering), AUTO and NAV, each mode
having a dedicated push button.
Each of the mode push buttons is clearly identified with the
primary function in large text, and a secondary function listed in
smaller text. Each button provides you with a multiple function
mode display.
Note ! WIND mode is not applicable, hence not available in a Volvo
Penta IPS configuration.
A group of user adjustable settings are provided in the AP16
User Setup Menu (page 26).
Alarms are presented in plain text to alert you of system and
external data failure conditions. Alarms include both audible and
visual presentations. The alarm listing is on page 79.
2.2 ON/OFF - Standby mode

Note ! When a NFU steering lever or a remote control is operated, the
control units become "Inactive".
2.6 Automatic Steering
When AUTO mode is selected, the AP16 automatically picks the
current boat heading as the set course and maintains the
simultaneous rudder angle. This gives a bumpless transfer at the
mode change.

When in AUTO or NoDrift mode (page 20) this feature allows
you to automatically cancel the turn you are in by an instant
press on the AUTO or NAV (NoDrift) button. The autopilot will
counteract the turn and the boat will continue straight ahead on
the heading read from the compass the very moment you pressed
the AUTO or NAV (NoDrift) button.

2.7 Automatic control of steering parameters
The AP16 provides two different sets of steering parameters for
controlling the response of the boat at different speeds while in
automatic modes.
The autopilot selects the LO (response) steering parameters
when engaging an automatic mode from STBY provided there is
no speed input. This is a safety feature. When entering an
automatic mode at low speed, the steering parameters may be
changed to HI automatically by input data from a speed log or a
GPS navigator (SOG), or manually.
The speed at which the autopilot automatically changes from LO
to HI parameters (or opposite) is determined by the "Transition
Speed" set in the Installation Setup Menu (Sea trial). See
diagram below.

Notes ! 1. If you are in NAV or NoDrift modes you need not enter
AUTO mode to manually change the parameter set. Just
make a quick double press on the AUTO button.
2. The manually selected setting (HI or LO) will override the
automatic selection and remain in effect until you re-enter
any automatic mode from STBY.
2.9 U-turn
This feature is very useful in a man overboard situation and
whenever you want to steer back on a reciprocal heading. It only
applies to power boats.
U-Turn changes the current set course to be 180 degrees in the
opposite direction. The user must decide whether the U-Turn
should be made to Port or Starboard when bringing the boat on
the new course. U-Turn is activated by a quick press on the
TURN/DODGE button. The AP16 will continue on the set
course until you press either the PORT or STBD button to select
the direction to make the U-Turn. If you do not press PORT or
STBD within 1 minute, the AP16 will return to the AUTO mode
and stay on course.

2.10 Dodge in AUTO
Dodging is useful in situations where you need to quickly take
control of the helm to steer around an obstruction, and then
resume the previous set heading. Dodging is activated by a quick
double press on the TURN/DODGE button.
When in DODGE mode the displayed set course is the last one
set prior to activating the dodge function. When DODGE is
displayed, the AP16 is no longer in control of the steering, and
you must either manually steer the boat in STBY mode or take
control using Non Follow Up steering. The AP16 will remain in
the DODGE mode until you exit DODGE by a second press on
the TURN/DODGE button or select a mode.
