The value is per-manently stored inmemory. In addition,total log distance is

permanently copiedinto all other displays in

the system, to provide abackup.

Total log distance is aglobal function in the net.

Alerts:

automatically, if morethan one display unithas been configuredfor the same log sen-sor.

All displaysshould be checked for

correct "SE" (see displayconfiguration).

Three dashes in-stead of the numbersare an indication thatno display has beenconfigured for a logsensor. Verify thecorrect SE=.. of theDisplay which has

the log sensor con-nected.

Low Battery AlarmThe battery alarm

comes on when thesupply voltage hasdropped below 10Volts. It disappearsafter voltage has ris-en above 11 Volts.The display stops

working below 9 Volts.

IlluminationIf you have a dim-

mer installed in thesystem, it must beused. Only without adimmer use the pushbuttons for illumina-tion control:

1. Press and holdall three buttons.2. Release SELECT

button first, then the others.3. Adjust brightness with left or right button.All other displays with the same group

number will follow in brightness.4. Exit from the dimmer function with the

SELECT-button.

The calibrationnumber can be en-tered only at thedisplay(s) where alog sensor is con-nected (and the Sen-sor Type Number hasbeen configured).1. Select Speed

Function2. Press both arrow buttons briefly.3. Adjust the calibration number "c" with the

left or right button. The calibration must bemade after installation, since the water speedin vicinity of the sensor may deviate by +/-20% from the boat speed, depending on thesensor location.

Standard Calibration Factor:Regatta Speed Sensor: C 50Cruise Speed Sensor: C 31Planing Speed Sensor: C 30Universal Speed Sensor: C 38Airmar Ultrasonic SpeedSensor (CS 4500): C 31

After modifying the calibration number, theindicated boat speed will change by the samerelative amount (e.g. changing the calibrationnumber from 50 to 55 will modify the speedindication from 10 to 11 knots).

An accurate calibration has to be done withthe Trip Distance counter. E.g. after running9,0 NM, the Trip Distance shows 10,0 NM. Inthis case, the calibration number has to bereduced by 10%. If it was 50, it should be setto 45 now.

If a weak set/current is present, the runhas to be made in two directions. Calibrationcan not be done with a strong current.

If desired, calibration can also be made inmph, km/h or m/s, except if a wind instrumentis connected to the bus, in which case the logmust be calibrated in knots.

Special case: should you wish to calibratetwo log sensors with different calibration num-bers, then the other display with the other logsensor should be disconnected from the busduring the process.

Log Calibration Log Speed received by NMEA:Log Speed (water speed) may be received

from a different instrument system throughNMEA data on any Tecnautic NMEA input(could be a Display unit, Fly-By-Wire unit,Autopilot Drivebox or Engine FADEC-Box).

The received log speed will be displayedand used in the same manner as if it werecoming from a log sensor. However it cannotbe recalibrated, and will not be used for thelog distance or trip counter.

Log Speed replaced by GPS-speed:In the absence of Log Speed Data, Water

Speed will be substituted automatically byGPS Ground-Speed.

This feature permits the use of the autopilotTrue Wind Mode, even in the absence of a logsensor.

Keep in mind, that True Wind data will beaffected whenever ground speed is not equalto water speed. With water speed available,true wind is shown relative to the water body.When ground speed is substituting waterspeed, true wind will be shown relative toground.

Remark: when water speed data are re-ceived from an external device and on a differ-ent NMEA-input than the GPS-speed, makesure that water speed data are received first,BEFORE GPS speed-data come into the sys-tem. The first source, with valid data will beused until next reset or power up of the unit.

means "notcompensated", means "compensat-ed".

ATTENTION: com-pensation status is not

correctly displayed aftera new installation or afterthe sensor or display havebeen replaced.

A new compensationcan be started by briefly

pressing the left or right button (see below).The middle button exits from the compensa-

tion function.

Starting a new com-pensation cycle

1. Select the com-pensation status on theDisplay (see above).

2. Briefly press theleft or right button.

3. Start turning (forthe HS8000 a star-board turn through 540degrees is required, forother sensors only a full

turn to either side isneeded).The turn has to be com-

pleted within one to three min-utes and must be executed under perfectlysmooth conditions. The vessel must not beheeled. Power lines or steel structures below ornear the vessel must be avoided. A significantdepth and a distance of several hundred meters(a few hundred yards) from bridges or buildingswould present acceptable conditions.

Completion of a compensation cycle is indi-cated by CAL-Auto (or by CAL-OFF if not suc-cessful).

WARNING: executing a compensation bearsthe risk of introducing large compensation er-rors. A bad compensation can only be overwrit-ten by a good one. The quality of a compensa-tion cycle has to be verified with a newly pro-duced deviation table.

Compass Compensa-tion: do alignment first!

Sensor compensation and alignment func-tion are only accessible on the display unit, towhich the sensor is physically connected viathe NMEA port, and the port has been proper-ly configured n0=01 for the primary compassor n0=02 for a secondary compass, andn1=00 for the HS8000 or n1=07 for the PB200or H2183.

Aligning the Sensor

Reading the previ-ously saved align-

ment correction

1. Press and holdleft and right button.

2. Press middlebutton twice.

3. Release allthree buttons.

For example"C_02" will stand for an

alignment correction of +2 degrees. The valuemay be modified with the left or right button. Thiscorrection is added automatically to the sensedheading. Press the middle button again to dis-play the compensation status function.

Alignment ProcedureFirst you need to create a deviation table. That

will be the basis for a correct sensor alignment.The deviation table might have positive and neg-ative numbers over the full circle.

A deviation table can only be created by tak-ing relative bearings of distant objects and com-paring them with the indicated heading. Neveruse GPS tracks to build a deviation table.

With the table at hand, adjust the alignmentcorrection "C" (offset) until negative and posi-tive deviation values become equal in size.

Note: on the PB100/200 sensor, the offsetcorrection will also be valid for the apparent windangle.

ATTENTION: the Alignment Correction maynot be displayed correctly after (re-) installingeither the sensor or the display unit, to whichthe sensor is connected. The correction mustbe verified in this case.

button.

The Heading GyroThe Tecnautic Sonic Gyro is a so called

Heading Gyro. As opposed to a north seekinggyro, it needs to be aligned externally. Thereaf-ter it still requires continuous slewing, to avoiddrifting away from north due to earth rotationand gyro drift.

The means for slewing the gyro can be se-lected in the sensor setup (page 27).

Beside of "not knowing NORTH", the head-ing gyro has all the qualities of a gyro compass,it is immune to linear acceleration and magnet-ic influences. It senses solely the instant rate ofturn and the heading of the vessel, without de-lay.

After power up, the gyro goes through anautomatic alignment and stabilization phase,which normally lasts five minutes. Thereafter itis available for use by the display and the auto-pilot.

Slewing by a Magnetic CompassWith a magnetic compass in the system, the

heading gyro can be slewed to magnetic north.Coupling of the magnetic compass to the

gyro is very weak, in order to avoid reflection ofshort term fluctuations (in the range of seconds)onto the gyro heading.

In the longer term however (within minutes),the gyro will be slewed to the average headingof the magnetic compass.

Slewing by a GPSWith a GPS in the system, the gyro can be

slewed to the GPS course. In this case the gyroheading represents course over ground insteadof direction of the bow.

Slewing to a GPS is halted below speeds of2 knots.

Course data from the GPS must not bedampened or delayed by more than one sec-ond.

Slewing a gyro to the GPS course is not rec-ommended in rapidly changing drift conditions.

Free running Heading GyroWithout a magnetic compass or a moving

GPS, there is no slewing of the gyro. Neverthe-less the gyro is available to the autopilot after aprolonged stabilization phase. The AutopilotHeading Mode cannot be selected from theHeading Display (which shows no heading inthis case), but from the tiller button.

The Turn-Rate Mode can be engaged fromthe Fly-By-Wire station. Small heading adjust-ments need to be made from time to time, tocounter the gyro drift.

The Autopilot Wind Modes are available un-restricted, the gyro drift has no effect.

Electric Helm connect-ed to an AP-Display

The potentiometer of an electric helm canbe connected to the sensor connection of anAutopilot Display. Such helm units are avail-able from various manufacturers. The helmshould have adjustable friction and musthave a middle detent, which can be felt, topermit easy centering the wheel. The displaymust be configured for sensor type SE=21, 22or 23 and display type di=01 (autopilot displayonly). The helm must be calibrated before useas follows:Calibration of the Electric Helm

The purpose is to adjust the potentiometershaft mechanically in such a way, as to havethe middle detent coincide with the middle ofthe potentiometer signal.

Here is the procedure:-- Place the helm into the middle detent andcall up the configuration mode at the AP-Dis-play, to which the helm is connected. The dis-play will show "Con-FiG".

-- Press the lower left button once and the dis-play will show the Serial Number.

-- Then press the lower right button: "MAnu"and the center-offset number will be displayed.(In case you are installing a new potentiometerinto a helm: rotate the potentiometer shaft butleave the helm resting in the detent. The aim isto get the smallest possible reading near zero.A number smaller than +/- 10 is good enough.Then lock the potentiometer shaft to the helm)

-- Next will be to store the center offset into thedisplay memory. This is done by pressing thelower left button, while the helm sits in the de-tent. The answer of the display will be "CAL."in case of a successful calibration.Return to normal operating mode by pressingthe OFF-button once.

ATTENTION: if "CAL." is not displayed at theend of the procedure, the electric helm mustnot be used. Repeat the procedure.

SE=21: Automatic Helm ActivationThe electric helm is activated automatically

when using it. The autopilot would change intoSERVO-mode, no matter in which mode itwas. An eventual warning message on theAP-display (red LED) can be extinguishedwith its OFF button. The warning comes onwhenever the autopilot has left an automaticmode, for example when it has switched fromHDG-mode to OFF- or SERVO-mode.

If another helm unit has been in SERVO-mode or FBW-mode, the same mode will bepresent on the newly activated helm and thepreviously used helm will become inactive.

The AP-Display of an active helm isflashing "MAnu", which stands for MANUAL.Inactive helms are blinking slowly ("MAnu") ifanother electric helm is active.

An electric helm can also be activatedmanually by pressing the OFF-button of theassociated AP-display, instead of rotating thehelm.

Once an electric helm is activated, use theOFF-button of the AP-display to toggle be-tween SERVO-mode and Fly-By-Wire mode(FBW). The FBW-mode can be recognized byan illuminated HDG-LED, next to the HDG-button of the AP-Display, same as in headingmode. The HDG-LED will be blinking duringturns, or will be steady lit, when going straight.That gives a visual indication on the display, tocheck if the helm is resting in its center detentor not.

FBW-mode: the vessel is holding it'sheading automatically, when the helm restsin the center detent. If the helm is deflectedfrom its center position, a certain rate of turnwill be commanded by the helm angle. Ruddermovement is fully automatic, to achieve thatrate.

Heading changes in FBW mode may alsobe made from the AP-Display, like in HDG-mode.

The electric helm becomes inactive wheneither another helm is activated or an autopilotmode is selected, or when a separate "WheelOFF"-button (see diagram at the left) hasbeen pressed. The helm and the autopilot willgo off, if the Wheel OFF-button is depressed.Such action will be necessary, if a mechanicalor hydraulic helm or a tiller shall be used forsteering.

SE=22 or 23:Activation of the helm is only done with the

OFF-button of the associated AP-Display. Therest is identical to SE=21 above.1:

Turn Rate ModeThe Turn Rate mode is the normal operat-

ing mode of the Fly-By-Wire Wheel. It is engagedby a second click on the SERVO button and in-dicated by a lit SERVO and AP LED. The Wheel

position determines the vessels'rate of turn. With a centered wheelin the detent, the heading will bemaintained. Use the SERVO but-ton to toggle between the SERVO

and Turn Rate mode.The rudder is controlled by the autopilot.

Heading changes can be made through theFBW-wheel or on an autopilot or heading dis-play.

Note: the Turn Rate mode is only availablewhen the heading gyro has completed its align-ment (5 minutes after power up). An operation-al gyro is also indicated by a dot behind the "H."on the heading display. The Turn Rate Mode isalways used while going forward.

In DOCKING MODE, it should even be usedwhile halted or moving astern, when vectoredthrust is available from the propulsion system(as with two individually steered rudders or sterndrives, or with bow and stern thrusters, or withjet drives). Use the FBW-wheel to change orkeep the heading.

The Docking Mode does not require the Tec-nautic FADEC system isntalled, it works alsowith conventional throttles or other brand elec-tric throttles.

Docking-Mode with Bow and SternThrusters

In Docking-Mode (the THR-LED is flashing)mainly thrusters will be used for steering bythe FBW-wheel, except in pure SERVO- Mode,where thrusters are commanded manuallythrough their toggles. Even the autopilot will beusing the thrusters, when in Docking-Mode.

Using the FBW-Wheel in Turn-Rate Modelets you turn the boat even at stand still or whilegoing astern, when the Docking-Mode is on. The

Rate of Turn is selected by theTurn Knob position. The boat isalways turning in the sense ofthe wheel, even when moving

astern. With a centered Turn Knob (in the de-tent), the heading will be maintained by theheading gyro.

In the presence of both Bow- and Stern-Thrusters, the boat can be commanded side-

ways by use of the for-ward toggle, when theTurn-Rate Mode is on.

The selected heading or rate of turn will be heldautomatically at the same time.

Docking-ModeAutopilot in Docking-Mode: the vessel can

be steered (turned) at standstill and also be shift-ed sideways. If available, Bow and Stern Thrust-ers will be used automatically. In the presenceof two engines they will be put into opposite gearand steered individually to different rudder an-gles.

FADEC in Docking-Mode: the system maybe configured to limit engine power in Docking-Mode, permitting large throttle movements forsmall thrust adjustments.

Changing into and out of Docking-Mode:The THR-button is used to select the Docking-Mode for steering and for the FADEC (if in-stalled). Switching in and out of Docking-Moderequires the engines either in NEUTRAL or inWARM-UP Mode. Hold the THR-button for 2seconds until it sends a short beep (without theFADEC system, press the THR-button only brief-ly). The Docking-Mode is indicated by a flash-ing Throttle-LED.

The steering functions of the Docking-Mode(rudders and thrusters) will not become activeif selected at high speed, until boat speed hasdropped below 2,6 kt.

Docking-Mode with individuallysteered Rudders or (Stern-)Drives

In Docking-Mode (THR-LED is flashing) bothrudders or both drives will be spread outautomatically by a certain angle. One enginehas to go into reverse, the other into forwardthrust. Use slightly above idle throttle settingseither way.

In case of fixed shafts, very effective ruddersare desirable, so as to deflect forward thrustenough sideways (since thrust will remainmerely straight on the reversing engine).

The simplest situation is with two Stern-Drives which are commanded separately by theautopilot. If only one engine is accelerated, theboat should move ahead or astern with a certaindrift angle, but without changing heading. Thespread angle is controlled accurately by theautopilot to maintain heading, when the FBW-wheel is in Turn-Rate-Mode (SERVO-LED andAP-LED will both be ON).

Semi-Automatic DockingIt is easy to move the boat purely sideways

with engines in Docking-Mode and the FBW-wheel in Turn-Rate-Mode: for moving toport, the port throttlewill be pulled into re-

verse just above idle and the starboard throttlewill be put into forward thrust, just above idle.

The Rate of Turn can be selected with theTurn-Knob. The heading will beheld, when the Turn-Knob iscentered.

To move ahead or astern,use only one throttle for adjustments.

The amount of sideways thrust is increasingwith engine speed (boats with a larger distancebetween drives will generally have more side-ways thrust available). To stop sideways motion,move the throttles to the opposite position.

Initial Operation

AP-OFF

WINDHDG NAV

1. Select Autopilot Configuration "-AP-"on any Autopilot Display (di=01) or on a Com-pass-Autopilot Display (di=02).

2. Briefly press left or right button (shows A0)3. Move rudder manually into center posi-

tion and rotate the sensor shaft manuallythrough 360 degrees, until the rudder LEDstands at 6 o'clock. Note: there might be a sec-ond shaft position with the LED in the middle,but the LED would not move gradually, whenturning the shaft. Use only the "good" shaft po-sition where the LED can be moved gradually.Then lock the sensor shaft to the rudder with itsarresting screw.

4. Rudder sense: use A0:00, move ruddermanually to port (for a left turn!) and observerudder LED also moving left. In case the LEDmoves the opposite way, set A0:01. Take a noteof the correct setting. Remark: one LED corre-sponds to three degrees rudder angle.

5. Attention: the rudder will move underpower during the following step! Be pre-

pared to press the "OFF"-button imme-diately if the rudder moves towards ei-

ther end. Exit the setup mode and press theHDG button on the autopilot display and modifythe selected heading by 2 degrees, or if you havea SERVO steering wheel with an OFF button,rotate it to the middle and press SERVO.

If the rudder moves to either end, press the"OFF" button immediately and switch off thepower to the DRIVEBOX.

In case of a reversible drive motor or in caseof Servo Valves, reverse the leads at terminals7 and 8 of the DRIVEBOX; for a continuousrunning pump and a proportional valve, reversethe leads for the valve at terminals 2 and 4 of

the DRIVEBOX. For Danfoss-Valves modifyA4* (0 or 1). Switch on power (again) and re-peat step 5.

6. Adjusting the rudder travel limits: Putyour rudder amidships, then engage the auto-pilot in heading mode. Modify the selected head-ing by 12 degrees right or left (or apply full de-flection on the Servo Wheel in "SERVO" mode,if there is one installed).

If the rudder reaches the mechanical stop,reduce A6 to a lower value. If however the rud-der does not come near the stops, increase A6if necessary up to its maximum value of A6=28.

Usually there is a slight difference betweenthe left and right side. The rudder sensor midposition should be adjusted mechanically soas to have the boat running straight with theSERVO wheel centered. It can also be adjust-ed within small limits by modifying A_.

Before going through thischapter, you should be familiarwith "Display Configuration" on

pages 26 .. 28

Setup ParametersSelect AP configuration (as shown to the left)

There are two sets of parameters. Selection ofthe set is done by A9.

A0:00 (00 or 01) Rotational sense of the rud-der angle sensor. See to the left.

A1:00 (00 or 01) Number of the Autopilot Drive-Box. In case of two independent rudders,number 00 must be assigned to port and01 to the STBD Drive-Box. With Danfossproportional valves, the idle signal canbe adjusted by A1 within 1%.

A2:00 Single rudder or two parallel rudders orJet- and Voith-Schneider Drives. Nospreading and no inverse motion.

A2:01 Single Jet-Drive with Bow Thruster.A2:02 One or two straight shafts with Bow and

Stern Thrusters. In Docking-Mode rud-ders are spread and rudder motion isinversed at the reversing engine.

A2:03 Two separately steered drives (propel-lers). Rudder motion always inverse atthe reversing drive. Spread rudder an-gles in Docking-Mode.

A3:01 automatic heading dead band 01=ON.The width of the dead band is deter-mined from actual boat movement un-der present sea conditions. The deadband leads to less rudder motion withonly slightly less steering accuracy,which is desirable for power saving onyachts and a less nervous helm on boatswith mechanical steering.

A4:08 (05..31) upper limit for rate of turn underautopilot (degrees per second headingchange). Warning: limit NOT applied inLAND-Mode!

The DRIVEBOX must bepowered and connected

to the bus. Make surethere is no secondDrivebox or FADEC-Box connected to thebus at the same time,when viewing the con-figuration! Verify the

rudder angle LED is lit inthe lower half (3 to 9o'clock), before proceeding(1 LED = 3 degrees).

A2*:00 Set A2*=00 when the rudder angle sen-sor is connected to the Drivebox. SetA2*=01 when the rudder angle sensoris connected remotely to the CAN-bus,for example to a display unit.

A3*:00 Type of rudder sensor: A3*=00 for 90-degree potentiometer. A3* must be setto 01 for 340-degree rudder sensor (re-quires Drivebox 40L or 08L hardware).

A4*:00 Only for two pumps working on thesame hydraulic system (assisting eachother), set A4*=01. With Danfoss valves,use A4* to reverse the output signal.

A5*:00 Set A5*=01 for voltage controlled (Dan-foss) proportional valves.

Installation: Servo Steeringwithout DisplayUse this page only if you have noTecnautic Displays installed:

Select set-up mode (see page 51)

1. Select set-up mode, function "P0":2. Move rudder manually into center posi-

tion and rotate rudder sensor manually so thatthe red and yellow LEDs appear to be both atminimum brightness (dim). Now lock the sen-sor shaft with its arresting screw.

3. Rudder sense: Move rudder manually tothe left (for a port turn) and observe increasingintensity of the left (yellow) LED. Moving the rud-der right increases the right (red) LED's inten-sity. If the intensities are reversed, set the jumperJP1 in the DRIVEBOX to its opposite state (e.g.from closed to open).

4. Rudder travel limit: Press the "SERVO"-button once. The red "AP"-LED should be lit forP1 and the yellow "SERVO"-LED should be off.

Move the rudder manually to approx. twodegrees before the mechanical stop of eitherside, then press the "AP"-button briefly. This willplace the present rudder angle into memory andthe drive will not go any further.

Exit the set-up mode with the "OFF"-but-ton(*).

5. Attention: the rudder will move underpower during the following step! Be readyto press the "OFF"-button(*) immediatelyif the rudder moves towards either end. Ro-tate the FBW Wheel to the center and press the"SERVO"-button (yellow SERVO-LED illumi-nates).

If the rudder follows the movements of theFBW wheel, go to step 6. If the rudder moves toeither end, press the "OFF"-button(*) immedi-ately and switch off power to the DRIVEBOX.

In case of a reversible drive motor or in caseof Servo Valves, reverse the leads at terminals7 and 8 of the DRIVEBOX; for a continuous run-ning pump or for a proportional valve reversethe leads at terminals 2 and 4 of the DRIVE-BOX. Then switch power ON again and repeatstep 5.

6. Verifying the rudder end limit: Press the"SERVO"-button (yellow "SERVO"-LED goesON) and rotate the FBW wheel to either side. Ifa mechanical stop can be hit (either within thehydraulic cylinder or externally), enter the set-up mode again (step 1) and repeat step 4, withmore distance from the mechanical stop.

NMEA data connection

The NMEA Input of the display unit canreceive signals conforming to NMEA-0183-V1.5 and V.2.0

The NMEA Output signal conforms toNMEA-0183 Version 2.x (symmetric signal)with a 5 Volts differential amplitude.

Therefore both version 1.5 and 2.x receiv-ers can be connected.

For single pole (Version 1.5) data receiv-ers, you should connect Tecnautic"Out-A" to"Data-IN" of the receiver. All equipment musthave a common supply GND in this case.

Activate NMEA-0183 output:It is important to make the necessary set-

tings on your Nav equipment (GPS, Plotter orPC), to activate the transmission of the routedata towards the Tecnautic autopilot and in-struments. Here are a few hints, for your con-sideration:

** The Tecnautic autopilot and displays usemagnetic bearings, not true bearings. It isrecommended to select also magnetic bear-ings in the setup of your GPS or Plotter.

** Create and activate a route in your Navequipment. Verify that bearing "C", cross trackerror ("r" or "L") and distance to the activewaypoint are displayed on your Autopilot Dis-play. At least bearing and cross track error arerequired to permit the use of the autopilot NAVmode.

** If your Nav equipment permits, activateonly the following output sentences: APB, RMCand WDC. If this selection is not available, useother sentences from the table on page 28 (low-er left), to receive the required data. For exam-ple RMC can be substituted by VTG, APB canbe substituted by (BOD+XTE), BOD by(RMB+RMC), WDC by BWC.

** Select a repetition rate of the sentenceoutput as high as possible on your Navequipment. This might be once per second,depending on your equipment.

** The accuracy of the cross track errordata (XTE) of the Nav equipment can be se-lected on some models. Select three (ormore) decimal digits, if possible.

The autopilot LAND mode must only beused, when at least three decimal digits ofthe cross track error are received. That has tobe verified on the AP-Display. The third deci-mal remains always zero, if it has not beenreceived by the autopilot - do not use theLAND mode in this case.

The autopilot NAV mode can be used withonly two decimal digits received. The resolu-tion of the cross track error is in this case only0.010NM (18.5 meters).

Configure the output of your GPS, Plotter or PC

** The way point switching law has to beset up properly in your Nav equipment. It isrecommended to select (switching to the nextleg) "when abeam", or even "before abeam",where "before" should be set to 5 seconds (or0,005 NM to 0,010 NM).

Without verifying this setting, your Navequipment might switch too early to the nextway point, already far ahead of the active waypoint.

** Curved tracks: If the Nav equipmentdoes not support curved tracks, you may splita curved approach into a series of consecu-tive short tracks. The difference to the nexttrack should not exceed 20 degrees, whenrequiring accurate tracking in Land-Mode.

Contemporary Nav equipment:All modern Nav equipment (GPS, Plotter,

PC) can provide the required basic sentencesfor the autopilot.

From the following NMEA sentences, spe-cific data fields are read. The data are usedfor displaying certain functions and for guid-ance of the autopilot in NAV mode.

Therefore always push the sensor down asfar as it will go. The paddle wheel must beoutside the boundary layer.

Align the sensor handle withthe boat axis.

WARNING: The Log Sensor (or alter-natively the sealing plug) must alwaysbe secured with the locking spring, to

prevent unintentional retraction by water pres-sure or other force.

Never grease the O-ring seals of the sen-sor, otherwise it might be pushed up by waterpressure towards the locking spring and thepaddle wheel will be fully or partly retracted.

Cruise-Speed, PlaningBoat or UniversalSpeed Sensor

Airmar CS4500 Ultra-Sonic Speed Sensor

How the Ultrasonic Speed SensorWorks

The speed sensor uses ultrasonic pulsesto collect echoes from small particles in thewater as they pass under two transducersembedded in the insert. These transducersmonitor the particles in their respectivebeams. As the boat travels through the water,both transducers “view” the same stream ofparticles.

Because it takestime for particles totravel between thetwo transducers, theaft transducer detectsthe particles laterthan does the foretransducer. By mea-suring this time lapse,

the instrument calculates the boat speed. Theultrasonic speed sensor requires particles inthe water to obtain echoes. If the boat is air-borne even for a short time or in highly aerat-ed water, the sensor will measure an incorrectspeed.IMPORTANT: The ultrasonic speed sensormust be in good contact with the water at alltimes for the sensor to function properly.

Compass and Heading Gyro InstallationCompass Sensor

After installation, the sensor has to bealigned parallel to the vessel’s axis. Improperalignment results in a constant heading erroron all headings, e.g. always +4°.

At first align the sensor roughly with themark, to point forward. The next step is tocreate a deviation table by taking relativebearings from deck. Use the vessel as a bear-ing compass for a known object and comparethe magnetic bearing obtained from the chartwith the displayed heading. Use the alignfunction as explained on page 7 and do acompensation cycle only in accordance withpage 7.

!

Install the sensor at a magnetically undis-turbed location. Steady magnetic fields are

allowed, if they do not cause morethan 20° deviation.

Only in cases without a Head-ing Gyro, should the sensor be in-

stalled near the vessels centerof gravity. Horizontal acceler-

ations will be minimal there.During prolonged

horizontal accelera-tions, the sensor willpick up part of thevertical componentof the magneticfield. This cancause largeheading errorsduring roll and

pitch motion inheavy seas.

The cable outlet of theHeading Sensor must pointdownwards and the markingmust be aligned with theforward direction of the boat.

Observe the maximum operating voltage ofthe sensor!

Be aware that the greatest danger lies inmovable magnetic objects like small radios,tools, keys, cell phones, the steering compassor a hand bearing compass. A good compro-mise for above points is often found in a cabi-

net where clothes are stored. Select amid level, not at the floor and not just

under deck. An anchor chain on deck couldmake your autopilot turn sharply! Also batter-

ies and their leads can producestrong magnetic fields when thebattery is charged or discharged; a

distance of two meters fromthese sources is adequate.

On steel hulls, an abovedeck installation is necessary.

The sensor cable may beextended as necessary.

Sonic Heading GyroThe TECNAUTIC Sonic Gyro is a strap down

heading gyro with a so called vibrating gyro ele-ment.

When connected to a properly configured dis-play unit, all compass displays in the system willdisplay the Gyro Heading (see compass andautopilot functions).

The Gyro Heading is neither fluctuating norhas it acceleration errors.

The Compass Sensor or a GPS is still need-ed to prevent long term drifting of the gyro.

Fluctuations of the Magnetic Heading Sen-sor have no effect on the Gyro Heading. The Son-ic Heading Gyro needs no damping and trans-mits all heading changes instantly.

For the autopilot the heading is transmittedwith a 0.1 degrees resolution every couple milli-seconds.

Installation:The Sonic Gyro must be

mounted vertically on a wallwith no or little vibration.

Attention: temperature changes can affectthe accuracy of the heading. Thereforechoose a location where temperatureis not changing rapidly, e.g. inside a

closet, and protect it from sunshine or otherradiated heat.

The Wind Sensor must be installed at theforward end of the mast top and its arm mustpoint forward, so as to give the most accuratereadings, when close hauled or reaching.

The direction of air flow is neverthelessaltered by the presence of the sail under-neath. To avoid the resulting inaccuracies oftrue wind direction, speed and VMG, the windsensor can be mounted on a small mastabout 2 m (7 feet) above the mast top.

The mast cable should be held at the masttop with a cable tie, in order to relief the plugfrom any strain. The cable must not come incontact with moving halyards.

Operating information: when powering upthe wind display, the anemometer wheel isdriven electrically for a period of two seconds,to break any eventually present cob webs.

FairingFlow DirectionAttention:

the fairing mustnot be too flat; otherwise theboundary layer would be deflectedonto the transducer face!

Non-aerated (bubble free)water must flow across thetransducer face at all

speeds if good depth sound-ing performance is to be

achieved. The transducer should be located,where the following conditions can bemet:

tightening from inside the hull.7. The transducer transmits also some en-

ergy sideways into the hull. If the returningechoes from inside the hull are strong enoughto be received, an acoustic isolation betweenhousing and hull will be required. Any soft(porous) material may be used.

1. On sailboats the transducer shoud bemounted where the acoustic beam will not beshaded by the keel. A spot forward of a finkeel is usually best. Try to find an accessiblespot with a minimum dead rise angle.

2. On displacement hull power boats (e.g.trawlers), the transducer should be mountedamidships, relatively close to the keel (center-line of hull).

3. On planing power boat hulls, the trans-ducer should be mounted well aft and close tothe keel to insure that the transducer is incontact with the water at higher boat speeds.If the vessel is capable of speeds greater than25 knots, you may wish to review installationlocation and operational results on similarboats before proceeding.

4. Never position a depth transducer direct-ly behind shaft struts, fittings and paddlewheel speed transducers, since the turbu-lence can adversely affect depth transducerperformance.

5. On I/O’s (stern drive) transducer mount-ing close to the engine(s) usually yields goodresults. On inboards always mount the trans-ducer well ahead of the propeller(s). Turbu-lence from props seriously degrades trans-ducer performance. Make sure transducer isnot shaded by the prop shaft(s).

6. It is very important that the mountinglocation have reasonable access from insidethe vessel since the transducer will require

8. At speeds above 10 kts the turbulentboundary layer will provide a shield for thetransmitted and received signals, preventingany echo sounder operation. To overcomethis, a fairing of non swelling material shouldbe fitted, to place the transducer face belowthe boundary layer.

Maintaining the DepthTransducer

Antifouling paint: If the vessel is kept insaltwater, sea growth can accumulate rapidlyon the transducer face and seriously reduceperformance in a matter of weeks. It is recom-mended that the external face of the transduc-er be coated with an antifouling paint. Useonly mineral spirits based antifouling paint. Donot use Ketone based paints since they attackthe potting materials used in the transducer. Iffouling does occur, use a stiff brush or puttyknife to remove growth. Wet sanding of fouledtransducer face is permissible with NR. 220 orfiner grade type emery paper (use plenty ofwater).

Provide a provisionalpatch of water at the de-sired location

Plastic hull (not to bevery thick)

Remove air bubbles!

Remove paint and insulation

Minimum gap 1 mm

Not more than 20 mmfrom the hull!

No bubbles under thetransducer!

2. Choose a location where the hull is notvery thick. Check also points 1) to 7) listedunder “location of depth transducer”. They areequally valid for a within hull installation.

3. The third step is toinstall the housing at thelocation determined. Selecta marine bedding / caulk-ing compound e.g. Sika221. Install vertically andfill with water or oil. Thetransducer face must be in

the fluid even when thevessel is heeled.

Standard installationwith through hull fitting

Advantage of a through hull installation is,that there are no doubts if and how well thesound waves will pass through the hull (com-pared to a within hull installation).

There are a few points to be considered forthe through hull installation:

1. The sensor shouldbe mounted verticallyand not inclined, nei-ther sideways nor for-ward or aft. If the hullis not level, a fairing

has to be fittedoutside andinside.

2. In case ofa wooden hull or

wooden fairings, useonly a metal through hull

fitting.Swelling of the wood may over stress the

plastic housing. Also hauling the ves-sel may over stress and crack the

housing.

3. Do not expose a plastic through hulltransducer to solvents. The

housing might crack andleak.

4. In case of a coredhull, make sure that nowater can enter into thecore. This might require

bonding of a tubeto the inner andouter hull, beforeinstalling the trans-ducer housing.

5. Do not use metal hous-ings on metal hulls. Electrolytic corro-sion will occur.

Always tighten the lid firmly!

Within hull installationThis kind of installation is only possible on

compact non porous plastic hulls.It is not recommended for boats faster than

10 kts.Steps of installation:

1. The boat must be in the water. A "sonicwindow" has to be found in the hull, wherethe echo sounder works! The first step is tofind a place where the sound waves can pen-etrate the hull without losses. This test is ab-solutely required, because there is no otherway to find out. The vessel must be in the wa-ter at a place where echoes are not absorbedby mud or other soft ground. This test can

best be done with the vesselunder way over different seabottom.

Rudder Angle SensorInstallationStandard version for mounting onthe cylinder piston rod

ATTENTION: The hook length must beadjusted so as not to interfere with the cylin-der, when the piston is fully retracted!

To adjust the hook length, proceed as fol-lows:

1. Remove the lid on top of the Sensor2. Unscrew the hook3. Adjust the hook length and tighten the

hook screws4. Close the lid

The hook must be bent so as to guaranteea firm grip of the piston rod, even when it ismoving vertically! There must be absolutelyno play.

WARNING: make sure the hook does notinterfere with the rudder arm at full rudderdeflection!!!

The sensor is supplied with a hook. Thehook is properly bent for a piston rod of 16mm (5/8") diameter.

A hole (6,5 mm / 2/8" diameter and 10 mm/ 3/8" deep) should be drilled along the axis ofthe bolt. A second hole with a 3 mm (1/8")thread is required to fix the shaft of the poten-tiometer in the bolt. For different conditions,the wire hook may be bent as required.

If the linear drive unit has been supplied byTECNAUTIC, the bolt with properly drilledholes is provided by the factory.

The rudder anglesensor must pick upthe rudder move-ment without anyplay.

Piston Rod of hy-draulic cylinder

Checking the Sensor after the in-stallation and setup procedure hasbeen completed

Do not proceed with this test before com-pleting the initial installation and setup (p.22)!

Switch on the SERVO mode, if anelectronic steering wheel is installed and turnthe wheel to the middle position.

Or, if there is no electronic steering wheelavailable, have the boat moored firmly, so asnot to change its heading. Place the rudderamidships and engage the autopilot HDGmode. Verify the displayed heading to be sta-ble, before engaging the autopilot.

The rudder should be steady at this stage.

Now try to apply very light sideways forcewith your finger tip onto the hook of the rudderangle sensor. If there is play, the rudder willmove. Eliminate the play!

Play leads to rudder oscillations and inac-curate steering.

Conventional Rudder Sensor Instal-lation

In case of an existing rudder actuator, itmight be easier, to install the sensor in a con-ventional way. Tecnautic recommends its

"sealed rudder sensor"(part nr. 23 00 03) forthat purpose.

There is no require-ment on the orientation of the sen-

sor. The sensor arm A and the effectivearm B at the rudder must be of equal length.Only with stern drives A can be bigger than B,to achieve larger rudder deflections.

Symmetric conditions are required in thecase of two independent rudders or sterndrives.

NOTE: there must be a 90 degrees anglebetween the arm and the connecting rod,when the rudder is centered.

Linear Drive Unit: InstallationElectro-hydraulic Linear Drive for Tiller-Steeringand mechanical Wheel-SteeringGeometric Situation

Fist of all, the geometric layout must be de-termined. The support with the joint at the rearcylinder end will be attached to the hull struc-ture. The piston rod will be connected to the rud-der arm with a bolt.

The cylinder may be mounted in front or be-hind the rudder shaft, the sense of rotation doesnot matter.

The piston rod must move in the same planeas the rudder arm. This is achieved by aligningthe cylinder support mounting surface perpen-dicular to the rudder shaft. The length of the rud-der arm "F" can be taken from the table nextside. The lateral distance "G" should be about(0.86...0.90)R.

The required length of the autopilot tiller armcan be determined after measuring the vessels'maximum rudder deflection: shortly before eachcylinder end position, full starboard or port rud-der should be reached. Do not use the cylinderas the mechanical rudder limiter.

The standard rudder angle sensor is provid-ing the rudder angle output signal for an angu-lar range of +/- 45 degrees.

The maximum available rudder deflectionunder autopilot or servo steering can bechanged. See "Autopilot Function / Initial Oper-ation" or "Control Wheel Function / Initial Oper-ation".

Installation HintsThe autopilot tiller arm must be locked onto

the rudder shaft by a key or wedge. Transmis-sion of the torque by friction alone requires avery heavy design of the arm.

In case a rudder quadrant is present, the pis-ton rod should be attached to it, eliminating theneed for a separate tiller arm.

The drive installation must be very rigid andstiff. Especially the distance between ruddershaft and rear cylinder mount must not changeunder the load of the cylinder force.

Installation1. Replace the transport tank cap with the

cap from the box; it has a breathing hole!2. Purge air now according procedure below!

Then remove the rudder angle sensor from thetiller arm bolt and keep it hanging on the cylin-der rod with its hook. Then tighten the tiller armbolt and the cylinder support screws. Reinsertthe rudder angle sensor into the tiller arm bolt,but do not lock its shaft with the M3 lock-

Purging the Hydraulic SystemBefore installation, it is necessary, to purge

air from the hydraulic cylinder and to add auto-matic transmission fluid to the hydraulic tank,but not more than half full. The "shipping" tankcap has to be replaced with the regular one,with a breathing hole, before moving the pis-ton and use of the drive.

For verification connect the Bypass Valve tothe battery. Even under great force, the pistonrod cannot be moved more than 1 mm (1/32in.) if air has been purged completely.

The following symptom will always requirepurging of the system:

If the rudder can be moved mechanically (bydirect force onto the rudder), when the autopi-lot or Servo Steering is engaged. Exception: verysmall movements of the piston (less than 1 mm)are permitted.

To purge air: disconnect the rudder and thesensor. Switch on SERVO or AP and turn thesensor shaft slowly until the piston hits the cyl-inder end firmly. Then hit the other end firmly.Repeat 10 times with full rudder speed.

!

ing screw yet. This will be done during "initialoperation".

Fill up the hydraulic tank half way (use auto-mobile automatic transmission fluid available atgas stations). Never use "hydraulic fluid"!Installation of detached pumps

The pump must be located higher than thecylinder. Air from the cylinder must be able toascend to the pump. The reservoir must be thehighest point in the system.Adjustment of pump flow

Some pumps permit mechanical adjustmentof the pump flow. Always select the maximumpump flow (factory setting).Rudder Speed Selection

A high maximum rudder speed is desirablefor good autopilot function. However it is a mustfor Servo Steering. A low maximum rudderspeed can lead to heading oscillations.Danger! Therefore the maximum availablerudder speed (pump flow) should alwaysbe selected. The Tecnautic Drive-Box is regu-lating the pump speed electronically and reduc-ing rudder speed automatically, whenever nec-essary.

The electric pump is normally mountednear the steering cylinder. Three hydraulichoses are required, to connect it to the steer-ing system. The wheel pump must have checkvalves installed or the Steering Wheel willstart turning, when pressure builds up fromthe electric pump. Some wheel pumps don'thave check valves; they require installation ofa check valve block next to the wheel pump.

Boats with two hydraulic steering wheelshave check valves already installed.

After making the required hydraulic con-nections, the system needs to be filled with oil.Automatic transmission fluid for automobileshas to be used. Purge air according instruc-tions for the steering system. Eventually re-peat purging after brief operation of the auto-pilot or Servo Steering. Some autopilot pumpmodels allow purging at the pump itself. Incase of pressurised hydraulic systems, do notexceed the prescribed air pressure.

Adjustment of pump flowSome pumps permit to adjust mechanically

their flow, to vary the maximum available rud-der speed. Always select the maximumpump flow.

Maximum Rudder Speed SelectionA high maximum rudder speed is desirable

for good autopilot function. However it is amust for Servo Steering. A low maximum rud-

der speed can lead to heading oscillations.Danger! Therefore the maximum avail-

able rudder speed should always beselected. The Tecnautic Drive-Box is

regulating the pump speed electronically andreducing rudder speed automatically, whenev-er necessary.

WARNING:If the autopilot does not keep the selected

heading (in HDG mode), the first thing tocheck is the stiffness of the hydraulic system.

Switch off the autopilot and the electronicservo steering. Then apply physical force ontothe rudder with the emrgency tiller. Do NOT(!)use the hydraulic helm. The piston should notmove more than 1 mm (1/32") at maximum.

1. Verify that there is no air in theram:

Disconnect the pump motor from the Drive-box, but keep the Bypass Valve connected.

Engage the autopilot now: the valve willclose and lock the rudder. Try to move yourhelm or tiller with moderate force to Star-board, then reverse your force to Port. Thepiston rod should not move more than 1 mm(1/32 in.) if air has been purged completely.Otherwise you have to purge the air from thecylinder.

2. Purging the last bit of air:Important: keep the purge valves closed (at

the ram and the pump), do not use them.Disconnect the rudder sensor mechanically

from the rudder, so it will not move, when therudder moves.

Further, we must be able to work the pistonto the very end of the cylinder, both sides.This will normally necessitate detaching thepiston rod from the tiller arm or quadrant. Orelse we might hit a mechanical rudder stop,before the cylinder reaches its limit.

Rotate the sensor shaft so as to get a cen-ter position on the LED of the autopilot display.

With the motor and the valve reconnectedto the Drivebox, engage the autopilot in Head-ing Mode (make sure the heading does notchange and the boat is moored firmly).

Turn the sensor shaft about three degreesto either side, this will start the pump. Don'tturn the sensor too far or the autopilot willdisengage. Stay there until the piston hits thecylinder end firmly. Then turn the sensor shaftquickly back to reverse the pump, and staythere, until the piston hits the other end of theram. Repeat that 10 times with full rudderspeed.

3. Verify again according step 1above!

Step P1: By pressing AP, the maximumrudder deflection is set to the actual rudder an-gle. Press SERVO briefly to advance to step 2,or press THR to exit the setup mode.

Step P2: (reserved function) Press SERVObriefly to advance to step 3, or press THR to exitthe setup mode.

Step P3: Press AP (the middle button) brieflyand listen to the number of beeps. Press APagain to increase the number of beeps. P3 se-lects the connected equipment (toggles or gyro).

When finished, press SERVO briefly to ad-vance to step 4, or press THR to exit the setupmode.

Step P4: P4 calibrates the throttle potentiom-eter after connecting it for the first time to thisFBW-unit or after reinstalling it.

When finished, press and hold SERVO toadvance to step 5a, or press and release theSERVO button to advance to step 5b, or pressTHR to exit the setup mode.

Step P5a: P5a locks the FBW unit, when theAP button is pressed before the SERVO buttonhas been released.

Step P5b: (no function) press SERVO brieflyto advance to step 6, or press THR to exit thesetup mode.

Step P6: P6 sets the illumination group num-ber for the unit. Press the middle button repeat-edly to select the desired number. Standardsetting is P6=1 (one beep), for group number 1.

Press SERVO briefly to advance to step 7, orpress THR to exit the setup mode.

Step P7: P7 sets the throttle lever type.Press the middle button to select the throttlelever type of this station. Setting the wrongnumber is dangerous and may cause unwant-ed switchings.

Press SERVO briefly to advance to step 0, orpress THR to exit the setup mode. Step 1 fol-lows again after step 0.

Step P0: P0 defines the right button function:P0=1: THR-button or P0=2: OFF-button (turnsoff the AP and SERVO-wheel).

Whenever unsure about the present stepnumber, press THR to exit the setup mode.
