Safety Instructions for the Installer

WARNING

Do not open the cover unless totally familiar with electrical circuits and service manual.

Improper handling can result in

electrical shock.

Turn off the power at the switchboard before beginning the installation.

Fire or electrical shock can result if the

power is left on.

Be sure that the power supply is compatible with the voltage rating of the equipment.

Connection of an incorrect power

supply can cause fire or equipment

damage.

Use the proper fuse.

Use of a wrong fuse can damage the

equipment or cause fire.

NOTICE

Observe the following compass safe distances to prevent interference to a magnetic compass:

	Standard	Steering
	Compass	Compass
Display unit	0.4 m	0.3 m
Processor	1.2 m	1.2 m

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.

FOREWORD

Thanks you for purchasing the ONWA KAP-866 Autopilot.

The KAP-866 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 ship's rudder. This must also be connected to the autopilot via the cable supplied.

KAP-866 is designed and constructed to meet the rigorous demands of the marine environment. However, no machine can perform its intended function unless properly installed and maintained.

Please carefully read and follow the operation, installation and maintenance procedures set forth in this manual.

We would appreciate feedback from you.

Thank you for considering and purchasing ONWA.

1.5.1 Weather Control

This setting is used for adjusting the autopilot's reponse on varies sea conditions. The weather value sets the desired accuracy of the vesse l steering. A high weather setting will cause the vessel to steer very accurately but may cause excessive use of the steering.

In good weather, set this control to a high value, but ensure that the drive arrows display on ship's heading field would not flickering continuously. This will give the straightest possible course.

In poor weather, reduce this setting to prevent over-working the steering.

1.5.2 Rudder Control (Rudder Ratio)

This setting		is used to determine the amount of rudder that the vessel requires
for	steering	(actually, the amount of rudder angle applied for a given angle
off	course).

The centre position is usually suitable for most vessels, but also should depends on the vessel's steering be sensitive or slow, adjustment maybe required.

In general, an agile vessel with a relatively large rudder or very small keel will require a small rudder setting. A large, slow vessel may require a high value for the rudder ratio.

5

This may also be adjusted according to speed, low speeds may require more rudder angle for steering than high speeds.

A value of 1 signifies the minimum amount of applied rudder (for sensitive steering, large rudders or low gearing ratio.

A value of 20 signifies the minimum amount of applied rudder (for vessels with slow steering, small rudders or high gear ratio).

When the rudder setting is too low, turns will take an excessive amount of time and the vessel may wander .

When the rudder setting is too high, turns will be rapid and the vessel will oversteer.

1.5.3 Counter-Rudder Control

In some vessels, changing course requires a large amount of rudder to be applied Initially, and then a smaller amount of rudder in the REVERSE direction to stop the vessel from swinging beyond its desired course. This is called counter-rudder.

The KAP-866 Autopilot has this feature built-in. A counter-rudder setting of "1" gives no counter-rudder steering, suitable for light and manouverable vessels. If you find your ship over-steering when under autopilot control, increase the counter-rudder setting by a couple of steps, and see if the next course change behaves better.

Once the correct setting is found for your vessel, it should not need to be changed. Unless the loading of your vessel is changed.

If you adjust the counter-rudder seting to "A" the counter-rudder functioning automatically apply depends on the rate of vessel turning to the set course.

The vessel		will begin turnin from its current course to the course requested by
the GPS Navigation.
If	no GPS	data is being received by the KAP-866, the autopilot will lock onto
the	course	of the vessel at the time that Navigation Mode was engaged, and the

No GPS Data alarm shall sound.

Setting up your GPS Navigator

Because there are a great variety of GPS Navigator that will work with this autopilot, the following is a guide only. For more information, Please study your GPS Navigator manual.

The GPS Navigator must be set up to output NMEA0183 data on a pair of wires which are connected to the "GPS IN" terminal connections on KAP-866.

The data generated must include at least one of the followings: The APA sentence.

The APB sentence.

The BOD and XTE Sentences.

If only the XTE data sentence is available, the pilot can steer in a Restricted manner. See later in this section.

The GPS unit must then be commanded to go to a waypoint, or to follow a line joining two or more waypoints (called a route).

This unit will then send information to the autopilot from which can be calculated the course-to-steer. IF several waypoints are linked together into a single route, and the GPS unit is set to "auto-sequenence" between them, and an "arrival zone" of more than 0.1 NM(Nautical Miles)is set so that the GPS can detect when the vessel has reached a waypoint, then the KAP-866 will be able to steer from each waypoint to the next without intervention.

If only the XTE information is available from your GPS unit then your vessel must be on track, and heading in the correct direction before engaging the GPS mode, and the auto-sequencing feature is not available.

8

Remember:

Prior to engaging Navigator mode, a route must be programmed into the GPS

for the Autopilot to follow.

No GPS Data Alarm

If the autopilot is not receiving valid information while in GPS Mode, the No GPS Data alarm will sound, and "NO GPS" will blink on the display. This counld be caused by:

Incorrect wiring of the GPS to the KAP-866.

Incorrect data output from the GPS unit.

No route set up or selected in the GPS unit.

No location fix at the GPS unit.

The bearings generated by the GPS unit must correspond to the bearings the KAP-866 is receiving from its magnetic compass. The greater the difference between these Bearings, the less accurate will be the Navigator mode steering. Ensure that the GPS unit has the correct magnetic correction factor.

Ensure that the KAP-866 compass is correctly aligned and installed.
