1. IntroductionThe Cetrek Pilot Computer is the heart of the autopilotsystem.

Two versions exist, the 930609 and the 930619. They bothlook the same from the outside but the 930619 has anextra Printed Circuit Board (PCB) inside to give it greaterfunctionality.

Both units have the capability of steering to a compasscourse, to a waypoint or to a constant wind angle.

The helmsman uses the autopilot control head to tell thePilot Computer what he wants it to do. The PilotComputer is told heading information by an electroniccompass sensor and is told the position of the vessel’srudder by a Rudder feedback unit.

The computer then processes the information availableand holds the straightest possible course. The software is‘adaptive’ which means it can be set to automaticallycorrect for changing sea conditions and for the vesselsown characteristics.

The system can have up to three separate navigatorsources connected via its NMEA ports, and the helmsmancan quickly select which to use.

This Guide explains how to install the Pilot Computer andwhere to connect the system components, optionalequipment and navigators. System components will haveinstallation instructions supplied with them.

1.1 Before you start installationBefore commencing the installation of the new systemplease carry out the following checks:

• that the items delivered are correct and undamaged ?

• that the drive unit is the correct voltage for the vessel ?

• if you are using a hydraulic pump, that you have thecorrect size fittings available to connect the pump ?

• that you have the correct type of hydraulic fluid to topup the steering system once the pump is installed ?

• that you have power cables of a suitable gauge tosupply power to the system?

• that you have Circuit Breakers to suit the system?

If you find an error please contact the supplier of theproduct immediately.

Before the drilling or cutting of any holes takes place,please consider the exact location and cable routing thatis required for each unit. Please read this installationdocument and any installation information supplied withthe individual units before you install the system.

All exposed moving parts must be sufficientlyguarded to prevent accidental damage to personsor clothing.

If it is necessary to extend the Drive Unit cables, theyshould be extended using a heavy duty cable, by theshortest possible route, to avoid unnecessary power loss.

All DC supply cables should be kept as short as possible,and should be taken from the battery via a switch/fuse orcircuit breakers of suitable rating for the system beinginstalled.

Two separately switched and fused power supplies mustbe connected to the Pilot Computer. The first is for thelight duty primary supply for the electronic control system.The second is for the heavy duty supply for the drive unit.

Avoid running power or motor supply cables, together orin the same conduit, with control and compass cables.This helps reduce the risk of interference.

It is good practice to cleat all cables to fixed points (notgreater than 0.5 m (18") apart) and where cables passthrough bulkheads, protect the cable with a suitablegrommet or sleeve.

If the vessel has a “clean” earthing system (i.e. using adyna plate or similar system) then the case of the PilotComputer may be connected to it using a heavy dutycable or copper strip, this will usually improve RFIrejection.If it does not, leave the the case isolated.

The negative of the battery system is not normallya clean earth and the case of the Pilot Computershould not under any circumstances be connectedto it.

Just in case Why not record the serial numbers of the units on page 59while they are easy to get at.

1.2 Suggested Installation StepsWe suggest that the following procedure will allow you toinstall the system encountering the least problems.

Read the documentation, then select the best positionsfor the units, then install the units in the following order:

Pilot Computer page 12

Autopilot Control, route the cable to thePilot Computer and connect it page 14

Compass Sensor, route the cable to thePilot Computer and connect it page 20

Rudder Feedback Unit , route the cable to thePilot Computer and connect it page 22

Drive Unit, route the cable to thePilot Computer and connect it page 24

Route the power supplies to thePilot Computer and connect them page 26

Optional Equipment, route the cables to thePilot Computer and connect them page 28

Carry out dockside settings and sea trials - see theUser’s Guide for the Autopilot Control being used.

1.3 Wiring Hints and Tips

Ensure that the Power is disconnected, beforeremoving the Component Cover.

All cable runs should be kept as clear as possible fromother cables carrying RF (radio frequency), pulsed signalsor heavy currents (such as winches etc.). At least 3 ft.clearance is advised. Take particular care to ensure themaximum clearance from radio transmitting aerials.

If it is necessary to extend any of the cables, the sametype of cable must be used. Screened cables must bebonded at the Pilot Computer as shown on page 13.

2. Installing the PilotComputerThis is the heart of the autopilot system and all unitsconnect to it.

Mount this on a vertical bulkhead in a dry, accessibleposition. Keep the heavy duty cable runs to the batteryand the drive unit as short as possible, but at least 1M (3ft)long. Short runs are particularly important on sailingvessels where battery life is an important factor.

If mounted in an engine room, ensure the area is wellventilated to avoid high ambient temperatures andabnormal condensation levels.

This equipment is capable of generating sparksand should therefore be mounted away from anyarea where there is risk of inflammable gases ormaterials.

To display instrument data (such as Speed or Depth) onyour 775, you will need an NMEA connection to theCartridge Reader. This can come from the instrumentsdirect, or preferably via the PL16 of the Pilot Computer.

The Pilot Computer combines NMEA information from its 3NMEA Inputs and its Instrument Input (PL12) into oneNMEA Output (NMEA3, PL16).

To feed this output to the 775, connect pins 3 and 4 ofPL16 to the NMEA Input of the Cartridge Reader.

Diodes are required across the solenoids, sometimes theyare built in, if not, fit 1N5401’s or equivalents, as close aspossible to the solenoids.

It is recommended that 5 Amp Fuses are fitted in the DriveLines to the Spool Valves.

The solenoids are wired ‘common ground’, ensureall other equipment wired to the solenoids is alsocommon ground, otherwise damage may occur.

6.2 Dual Rate Output

When the autopilot applies more than 10º of rudder, PL6outputs a signal. This can be up to 5 amps at the heavyduty supply voltage. It is intended for hydraulic systemsconfigured for dual rate operation.

6. Connecting a Drive UnitSee the documentation that came with your drive unit forinstallation advice.

InstallationStep 6

Two wires from the drive unit motor connect to PL2.Polarity is not important at this stage.

If the cables need to be extended, ensure that the correctcable rating is used.

The table on page 26, for the heavy duty supply, can beused as a guide in case of uncertainty

If a clutch solenoid needs controlling, connect it to PL1, asshown below.

If the vessel has a “clean” earthing system (i.e. using a dynaplate or similar system) then the case of the Pilot Computermay be connected to it using a heavy duty cable or copperstrip, this will usually improve RFI rejection.

If no such system is available, leave the Pilot Computerisolated.

The negative of the battery system is not normally aclean earth and the case of the Pilot Computer shouldnot under any circumstances be connected to it.

The power supply cables should not be used to supplyboth the autopilot and other electronic equipment asswitching transients can be very troublesome and thispractice can cause RF interference.

Maximum system performance and minimum cable losses are ensuredby using a cable size bigger than the minimum recommended.

7. Connecting Power to thePilot ComputerWire the power to the 609/619 from the ships electricaldistribution box circuit breakers, or via switches andanti-surge fuses.

Two separate cables need to be used, one for the heavyduty and one for the light duty, even though on a lowpower system they may come from the same source.

InstallationStep 7

RECOMMENDED MINIMUM CABLE SIZE for the HEAVY DUTY SUPPLY

It is important that the Heavy Duty Supply cables are of agreater current rating than the Drive Unit motor.

For example, if your motor is rated at 10 amps, the cablerun is 4 metres (12 feet), use at least 20 amp 2 core cableor 30 amp single core cable.

8. Connecting OptionalEquipment

8.1 Connecting NMEA devices to a 609The 609 version has one NMEA input/output port, NMEA1(PL11).

An LED adjacent to the NMEA connector will flash aboutonce a second as input dyata is detected. If it is on most ofthe time and flickering, the input signal polarity isprobably wrong.

PL12 can be used as an input for Instrument data.

NMEA output is from pins 3 and 4 of PL11.

All NMEA sentances supported are listed on Page 48.

Ensure that you observe signal polarity.

Connecting other NMEA DevicesNMEA instrument inputs, such as a Windvane or Speedand Depth Instruments, connect to pins 1 and 2 of anyNMEA port not used by a navigator.PL12 pins 3 & 4 can be used for instrument data if there arenot sufficient NMEA ports. PL12 cannot read navigatormessages.

8.2 Connecting NMEA devices to a 619The 619 version has three NMEA ports, NMEA1 (PL11),NMEA2 (PL17) and NMEA3 (PL16).

An LED adjacent to each NMEA connector will flash aboutonce a second as input data is detected. If it is on most ofthe time and flickering, the input signal polarity isprobably wrong.

PL12 can be used as an input for Instrument data, but notfor navigator data.

The 930619 combines NMEA information from the 3 NMEAinputs with NMEA Instrument data from PL12, into onemessage. This combined message is then output fromNMEA3 (PL16) pins 3 and 4.

To display instrument data (such as Speed or Depth) onyour 780, you will need an NMEA connection. This cancome from the instruments direct, or preferably via thePilot Computer.

The Pilot Computer combines the NMEA information fromits 3 NMEA Inputs and PL12’s input. It combines this intoone NMEA message which it outputs from NMEA3 (PL16).

To feed this output to the 780, connect pins 3 and 4 ofPL16 to the NMEA Input of the 780.

10.‘On’, ‘Port’ and ‘Stbd’SwitchesOnce the basic installation is complete, the 3 switchesabove PL12 and PL13 can be used to check the installation.

The middle switch turns the Pilot Computer ON provided ithas power to it. An Autopilot Control does not need to bepresent. It will NOT turn the unit Off, the power must beisolated to do that.

Powering up with the Port button held down forat least five seconds, overrides the ruddersettings alarm. This allows the motor to be runbefore doing the Dockside settings rudder setup.

The other two switches activate the motor output todrive the rudder to port or starboard depending on themotor phasing.

These switches may be used as an initial check that themotor cables and linkages are correctly installed, or tohelp bleeding hydraulic systems.

Be sure that the rudder can move from hard-overto hard-over without damage. Rudder limits maynot have been set.

13.Changing EpromsThe software is stored in the EPROM IC3.

EPROMS are Static Sensitive Devices. Take suitableprecautions when handling them.Fitting the EPROM reversed will cause permanentdamage to the new EPROM.

• Disconnect the Power.

• Release the quarter turn fasteners and remove the cover.

• Release the retaining screw, then remove theComponent Cover.

• IC3 is located in thecentre of the PCB.Carefully prise theEPROM from its socketwith a smallscrewdriver. Be surethat you do notdamage any tracksunder the chip.• Align the indent onthe new EPROM withthe indent marked on

the PCB. Check that all pins are over the individual ICsockets, then push down firmly in the centre of theEPROM. Ensure no pins are bent or have failed toenter the socket.

• Re-assemble the covers.

• Restore the Power supplies

• Turn the autopilot on. If system fault ‘SFLT 002’ isdisplayed, switch the Autopilot Control off and onagain, this should clear the condition (this must bedone at the Autopilot Control, not the circuit breaker).

• If the system will not stay powered up when theStandby key is pressed, it is almost certain that theEPROM has not been fitted correctly. Check and retest.

• If the display remains blank but the system has power,then check the EPROM is correctly fitted.

The Fail Safe Watchdog is causing system power down. A faulthas been detected on the Pilot Computer PCB. Remove the topcover and component cover from the Pilot Computer. Visuallycheck that the socketed IC3 Eprom is installed securely. Checkfor any loose material that may cause shorts.

If new software has just been fitted, check the IC legs. Damagedlegs will probably mean a damaged eprom.

The heavy duty supply and motor output cables are swappedover. Switch off immediately.

3. The displayworksmomentarilythen blanks andthe systempowers down.

See 1 and 2 above.

This could occur if RF energy is being injected into the powercables or by radiation injection into the pilot system componentsat very high levels. The autopilot has been exhaustively tested towithstand RF injection and radiation at levels far above thoseconsidered safe to personnel. Antenna mismatch yielding highstanding wave ratio (SWR) can cause dangerous conditions andin the interest of operator safety the radio installation should beinspected immediately.

A more normal problem to occur is that a Radio transmitter, orother high current unit, is being supplied from the same batteryas the autopilot. When the device is operated, it may be causingthe battery voltage to drop below that required to maintain theautopilot operation. Once power loss has occurred, the fail-safewatchdog has been designed to power down the system

16.Troubleshooting GuideAfter installing the system according to this manual itshould work faultlessly. In the unlikely event of a faultoccurring, here are some notes that might get you out oftrouble.

General 1. Ensure all supplies are turned off before connecting orPrinciples & disconnecting wiring. Certain components will beCautions seriously damaged if inadvertently shorted out.

Damage caused in this manner is not covered bywarranty.

2. When first installing or when changing the wiringalways double check the colour coding beforeswitching on the power.

3. Check all wiring is correctly connected according tosteps 21-8.

4. Do not use a simple voltmeter to attempt to checkpowered up digital logic lines or signal lines.

5. Ensure that all cable screens are properly earthed.

6. Check the fuses and replace blown ones with directequivalents. Most units have one internal fuse, thePilot Computer has 4.

7. Take suitable precautions when handling PCB’s withStatic Sensitive Devices.

8. Read the ‘Wiring hints and tips’ advice on page 10.

Symptom Possible cause and remedy.

Check the breaker and both heavy and light duty power suppliesto the Pilot Computer.In the Pilot Computer:Check Fuses F1 and F2. Check the supplies from the PilotComputer to the Control head.For control heads connected to PL14 or PL15, check that pin 1,(normally 4 to 5V) changes to 0V when you try to turn theautopilot on, if not, then suspect a fault in the Pilot Computer.Check that pin 2 is normally 0V and changes to +5V when youtry to turn the autopilot on. If this is not so then a fault with thePilot Computer PCB is likely.

automatically. This would be particularly noticeable if the batteryhad a bad cell or corroded connections. It is recommended thatwhere possible the autopilot is supplied with power from adifferent battery to the other auxiliary requirements.

This may happen very occasionally due to a momentary loss ofsynchronization during power up. The self test software reportsall errors of this type to help anticipate potential problems.Unless this happens repeatedly it is of little concern.

Check the heavy duty supply to the Pilot Computer.In the Pilot Computer:Check fuse F1.

If you suspect a faulty motor, test it by powering the motordirectly from a suitable battery.

Normally this can be traced to a wiring error. System faultmessages are explained and action to be taken is given, in“System Messages” on page 52.
