Autopilot
Warning!
Automatic pilots are designed to be a navigational aid. As an automatic steering
aid, an autopilot can alleviate the boredom of hand steering.
This allows the operator of the vessel time to attend to other duties, keep a more
accurate check of navigation duties or just relax and enjoy the trip.
HOWEVER, THE AUTOPILOT SHOULD NOT BE LEFT SOLELY IN CHARGE
OF THE VESSEL AND AN ADEQUATE WATCH SHOULD BE MAINTAINED
AT ALL TIMES.
IT IS NOT RECOMMENDED THAT THE AUTOPILOT BE USED WHILE
NAVIGATING IN RESTRICTED WATERWAYS AS WATER CURRENTS,
WIND CHANGES OR RADIO TRANSMITTER INTERFERENCE MAY AFFCT
VESSEL COURSE SUFFICIENTLY TO ENDANGER YOUR OWN OR OTHER
VESSELS.
Introduction
The KAP-833 autopilot is a hybrid of digital and analogue technology to give
the best of both worlds - excellent steering characteristics with digital compass
display, keypad course input, GPS and gyro interfaces, and much more, in solid
metal case.
The KAP-833 Autopilot controls the vessel steering through mechanical drive,
reversing pump set ,solenoid valves or relays.
The compass must be installed in a place free of magnetic interference, and
connected to the autopilot via the cable supplied.
The rudder feedback must be attached to the rudder in such a way that it can
accurately measure the position of the ships rudder. This must also be
connected to the autopilot via the cable supplied.
Provision has been made for two hand remote, panel remote, steering lever
or steering wheel stations. These are very robust units, which will not be
adversely affected by water. The abilities they provide are somewhat different
from the main control panel. See the Operation section of this manual for details.
For more in formation on installation of your KAP-833 autopilot, see the
Autopilot Installation section of this manual.

Operation section of this manual.

Autopilot OperationAutopilot Operation
Overview of Operation
The following is a brief list of the capabilities of the KAP-833 autopilot. Each
described in more detail in a separate chapter.
Note: Power to the KAP-833 is supplied via Weather control. Turn the knob
control in a clockwise direction to apply power to the KAP-833; this will
initially put the KAP-833 into Standby mode.
Standby Mode
The digital display shows the current magnetic heading.
The autopilot will not apply any steering control.
Auto Mode
The autopilot will maintain your vessel on any desired magnetic course.
This course can be set from the control panel by dialling up a course
change with the course knob, entering a course from the keypad, or
recalling a stored course with the PRESET button.
Power Steer
The rudder angle may be controlled by the course knob on the main
panel or from one of the remote steering stations.
GPS Mode
When receiving information from a GPS unit, the autopilot can steer a
vessel to a precise latitude and longitude.
Stopwatch Timer Mode
A timer can be set for 1 to 60 minutes. When the time expires, an alarm
will sound. Uses include timing of trawling runs, or a reminder to check
for anchor drag at set periods during a storm.
Remote steering stations
Two of these may normally be fitted (eg on each side of the bridge),
allowing adjustment of the autopilot course, or direct control of the rudder
(power steering). An optional third steering lever may be connected to
the control unit, subject to a special order at time of delivery.
Rudder Ratio, Weather and Counter Rudder
These controls customise the KAP-833 for your vessel. They may also
be used to adjust steering for varying sea conditions.
11
1
Turn Weather control knob clockwise to switch KAP-833 on to Standby mode.
In this mode
The Main and Standby lights are on
The motor clutch is disengaged
No steering control output is generated
The commercial watch alarm is turned off (if enabled)
The digital display shows the vessels current magnetic course
Possible alarms
Stopwatch timer alarm
If the option of Electric steering is enabled, this mode may not be
available and the unit will go direct to power steer on turn on.
Standby Mode

Engaging Auto steering mode
When in Standby Mode and the AUTO key is pressed, a beep will
sound and the adjacent yellow light will be turned on.
The autopilot will lock on to the heading indicated.
Disengaging the Autopilot
Press the Standby button. A beep will sound and the vessel will return to
manual steering (Standby Mode). The AUTO light will be turned off and
STANDBY light turned on.
Course Adjustment
Pressing the port (red) or stbd (green) arrow keys will cause a one degree
course change in that direction. The display will change to indicate the
new course-to-steer.
Rotating the course-change knob will change the course-to-steer by one
degree for each click .
Entering a course from the keypad, and pressing GOTO will change the
course-to-steer to the bearing entered.
Auto Mode

3
Engaging Power Steering Mode
Press the Power button. A beep will sound and the adjacent light will come
on. The rudder will move to the centre position.
Setting the rudder angle
The angle of rudder applied depends on the amount of rotation of the
course knob.
The maximum angle of rudder is controlled by the internal and external rudder
limit settings.
Power Steering Mode
4
Rotating the course control knob clockwise will move the rudder to
starboard. Rotating the course control knob anticlockwise will move the
rudder to port.
For information on power-steering with a remote unit (eg: Electric Wheel or
Steering Levers), see the section on remote units.
If your vessel requires counter-rudder while steering in auto mode, you may wish
to set the counter rudder control 1 (ie: disabled) while using power-steer.

Disengaging GPS Mode
Setting up your GPS unit
Because there are a great variety of GPS units that will work with this
autopilot, the following is a guide only. For more information, consult your
GPS manual.
The GPS unit must be set up to output NMEA0183 data on a pair of
wires which are connected to the GPS In terminal connections inside the
KAP-833. The data generated must include at least on of the following.
GPS Mode
5
For use when interfaced to a GPS generating NMEA 0183 data output. While in
auto mode this allows the autopilot to be directed by the GPS, enabling automatic
heading changes and eliminating the effects of wind and tide.
The digital display indicates the course-to-steer, which will be the bearing
between the origin and destination waypoints, plus a factor to correct for the
current cross-track-error (XTE).
Pressing the Auto key will set the KAP-833 to Auto Mode.
Pressing the Standby key will return the pilot to Standby.
The APA sentence.
The APB sentence.
The BOD and XTE sentences.
If only the XTE data sentence available, the pilot can steer in a restricted
manner. See later in this section.
5
When in any mode, press the GPS key. A beep will sound and the
adjacent yellow light will be turned on.
The vessel will begin turning from its current course to the course
requested by the GPS unit, at a maximum rate of 10 degrees per second.
If no GPS data is being received by the KAP-833, the autopilot will lock
onto the course of the vessel at the time that GPS Mode was engaged, and
the No GPS Data alarm shall sound.
