Wind modeThe Tillerpilot will tack the vessel through to the same apparAs a safety feature the Tillerpilot will only allow an autotack if the apparent wind is less than 90 ie autotack is disabledIn this mode the Tillerpilot automatically prevents tacking in the wrong direction if on Port tack only an autotack onto Starboard tack will be Port or Starboard LED flashing during the course243 Autotacking in Nav modeAs the Tillerpilot will be steering directly to a waypoint theby pressing the NAVkey then perform the autotackARNING Ensure that the boat is on the correct tack before reengaging Instruction manualTP22TP32 FEATURESThe TP22 and TP32 Tillerpilots contain many advanced features one of which is the ability to accept course data from avariety of sources apart from the internal fluxgate SimNet and NMEAcompatible etcAn external31 Nav modeThe Tillerpilot can interface directly with compatible Simradan inbuilt NMEAinterface which allows connection toOnce interfaced

TillerpilotThe Starboard LED will illuminate to indicate that Gain adjustment is selected To toggle between Gain and Seastate adjustment press the Port LED will illuminate for Seastate43 Adjusting GainThe Tillerpilot will apply adjustments to the tiller in order tobeing proportional to the heading error detected by the comtimes referred to as the rudder ratiohigh speeds very little wheel movement is necessary to steerthe vehicle LOW gainewheel movement is necessary HIGH gainFig 44 shows the effect of setting the Gain too low vessel takes a long time to return to the correct heading shows the ideal setting where errors are quickly the effects of setting the Gain too high whichcauses the vessel to oscillate around the correct headingeates a tendency to instability of courseleading to increasing error42 Calibration modeillerpilot is in either Standby or Autopilot modePress and hold the key then press manualFig 45 Increasing Gain levelWhen Gain is selected the Nav LED will flash

Adjusting SeastateIn heavy seas more variations in heading will be detected andif the Tillerpilot tried to respond to all of these errors it wouldtors the corrections applied over the course of a voyage andallows a dead band within which the boat can go off coursewithout constant corrections being made Fig 46the dead band is normally automatically adjusted by the Tillerpilot to give the best compromise between course holding andbattery consumption but it can be set manually if desired In Calibration mode press flashes of the Nav LED indicates that the Tillerpilot is set toPort Starboard

astraight course An example is when sailing close hauled whereapplies a standing helm to leeward in order to maintain courseThe amount of this standing helm varies according to factorssuch as strength of wind boat speed sail trim and amount ofsail set If no account of these were taken then the vessel wouldtend to veer off course or pull around headtowind when sailThe Tillerpilot continuously monitors the average course errorcondition is reached Fig 47applied gradually so as not to upset the normal performanceof the Tillerpilot Thus it may take up to a minute or so to after changing tack Once optimum trim is reachedthe pilot will still monitor for changes in the prevailing conditions and update the trim Fitting the TillerpilotThe Tillerpilot is a very sophisticated piece of equipment andtherefore in order for it to function to its full capabilities it isessential that it is installed correctly Please read this before attempting installation and useThe Tillerpilot should be horizontally level when fitted to theith the tiller amidships and the pushrod in the midstroke position the Tillerpilot should be exactly 90 to the tiller Fig 52Fig 51 Installation cross sectionThe pilot is factory preset to be mounted on the Starboard side as shown but this can be reconfigured for Portside mounting The dimensions given in Figures 51 and 52 should be adheredthe distance from tiller stock Fig 52illerpilot may require a Gain adjustment to TillerpilotIf the dimensions given are not practical for the vessel to which the Tillerpilot is to be fitted a range of fitting accessories are available to facilitate correct installation Please refer to section64 for more detailsThe Tillerpilot houses an internal fluxgate compass and should therefore be mounted away from sources of magnetic interference such as the vessels steering compass The minimum safedistance is 1m 3ft 3inThe Tillerpilot is mounted using a supplied tiller pin that this is on the centreline of the tiller and is Fig 53pit seat and mount so that only the flange protrudes Ensure theits entire depth if necessary reinforce the underside of thecockpit seat with hardwood or marine plywood Fig 54Due to the high loads exerted do not fit the Tillerpilot to the Instruction manualFig 55 Tillerpilot bulkhead socket wiring52 Electrical Tillerpilot operates from a 12v DC supply The waterproofplug fitted to the Tillerpilot is used to supply the power SimNetand NMEAdata tion close to where the Tillerpilot is to be fitted and wired asIMPORTANTIf the vessel has more than one separate battery bank when connecting the Tillerpilot to the power supply always ensureor NMEA are connected to the same battery bank even ifthey each have independent connections to the switch panelThis is to avoid a possible voltage drop between the which would render the equipment inoperative Mount the bulkhead socket on a vertical surface to prevent standing watergathering around or in the socket Always fit the protective cap when the No power is supplied to or from the SimNet bus the Tillerpilot must Use a suitable gauge cable to run from switch panel to the socket see Fig Connect to the vessels switch panel via a 10Amp fuse or breaker Do not fit other electronic or electrical equipment to the supply cable ortap into the supply from a nearby cable always wire each piece ofequipment to its own breaker in the switch panel Ensure all wire ends are tinned and any connections are well made Poorcontact will result in loss of thrust from the Tillerpilot and slower speedof responsecable runUnder

department for adviceDue to the limitations of NMEA0183 it is recommended that only one talker is transmitting to the Tillerpilot at any one time ie instruments If more than one unit needs to be interfaced to the should be connected to the NMEAcable via a of the vast number of different manufacturers andcorrect operation and installation of this equipment connecting any equipment to the Tillerpilot it is important that the units manual is referred to with regard to inter55 Electronic interference suppressionThe Tillerpilot has been designed to minimise the effects ofinterference generated by the engine alternator However precautions should still be taken by routing the cables away fromthe engine compartment Do not run the cables down high current or radio antenna cablesEngines with spark ignition also some refrigerators should befitted with suppressors Your local agent should be able toadvise on this and supply suppression kits where Tillerpilot56 Auto compass the Tillerpilot is installed it is necessary to calibrate themetallic or magnetic objects surrounding it on the vesselith the vessel motoring slowly 23 knotsand the Tillerpilot in Standby mode press the Starboard key a number of times to induce a slow clockwise rotation ofthe vessel Then press and hold the key followed by thePort Starboard The Port and Starboard LEDs will both light Allow the

turn Ashort beep will indicate that the calibration has beensuccessful and the Tillerpilot will return to Standby mode Ifthe calibration has been unsuccessful after a period of four minIf the calibration routine keeps failing after repeated attempts this indicates that the Tillerpilot is experiencing excessive magnetic deviation that it cannot compensate for Check the areawithin 1m

to the SimNet busand it will automatically detect the nav and instrument datasources with no user intervention necessaryIf the SimNet bus includes more than one data source theillerpilot will use the first source it detects Fig 511In the example above there are two nav data sources the and the NMEAGPS via the IS12 Mega instrumentand two external heading sources the IS12 Compass and theRFC35R Rate Compass via the AP25 the heading data source However the Tillerpilot may automatically select the IS12 Compass as the heading data sourceand it may select the Mega instrument as the nav data sourceIf these are not the desired sources they can be manually configured Two operation modes are availableThis is the default setting the Tillerpilot its own data sources but it can be reconfigured touse

that the Tillerpilotwas previously locked ontoPOWER6 APPENDIX61 Advice on operationWhen used correctly your Tillerpilot can maintain as good aadvantage that it never gets distracted whereas a human canHowever there are certain circumstances where a human hasfollowing advice should improve efficiency when sailing usingyour Tillerpilot1 When sailing close to the wind it is easy to forget to trimthe mainsail allowing excessive weather helm to build upWhere a human helmsman would quickly complain the autopilot will struggle on and the boat will be sailed less a human normally likes to feel some weather helmthis is not necessary for the functioning of the consumption wear and drag will be greatly reduced ifthe mainsail is freed or reefed a little sooner than normal whensailing manually2 It is also advisable when sailing close hauled to set acourse a few degrees free of that normally sailed under manualcontrol to avoid luffing into the wind3 When running dead downwind a human pilot can seethe Tillerpilot cannot sense it is advisable not to sail as closeto the gybe as you may do when sailing manually4 When broad reaching or running fast particularly withlarger angles of helm than when beating or sailing slowly Thisis the equivalent of increasing rudder Gain and it may be agood idea to adjust the Gain on the Tillerpilot Many peopleprefer to find a compromise setting which is used for all sailing but with practice it can be optimised for different conditions eg low for motoring in a calm sea or high for runningfast If the Gain is set too low the boat will go off coursebecause insufficient rudder is applied in time if the Gain is toohigh the boat will overcorrect increasing power consumption5 The Tillerpilot is a highly advanced piece of it would be a mistake to become complacent Aswith all electronic navigational equipment it is an aid to practice Remember Maritime Law requires manualTP22TP32 Tillerpilot62 Fault findingThese simple checks should be
