General Information 1 GENERAL INFORMATION 1.1 Introduction Congratulations on the purchase of your new Simrad AP35 autopilot system and thank you for selecting what we feel is the most advanced autopilot system available on the market today. Today Simrad manufacture a complete range of autopilots for all types of vessels, from leisure boats up to advanced steering systems for merchant marine vessels. Our factory for these products is located in Egersund on the south/west coast of Norway.
Simrad AP35 Autopilot 1.3 System components A basic AP35 system consists of the following units (refer to Figure 1-1): • AP35 Control Unit with accessories • Heading sensor • Rudder Feedback Unit with transmission link • Junction Unit • Drive unit The basic system can be expanded with remote control unit, hand held remote and steering lever. Figure 1-1 AP35 Basic system 1.4 AP35 Control Unit A compact autopilot control for panel, bulkhead or bracket mounting.
General Information 1.5 Junction units The junction unit is the central in the AP35 autopilot system. It contains the steering computer, interface circuits to all system components and drive circuits for the drive unit motor and clutch. Three models, J300X, J300X-40 and J3000X are available.
Simrad AP35 Autopilot RC25 Rate Compass Fluxgate compass with integrated rate of turn sensor. Provides a dramatic improvement to the dynamic performance of both the autopilot and a stabilized radar display. Same dimensions as RFC35. Magnetic Compass Most liquid filled magnetic compass with external 2 axis gimbals can be interfaced by using CD100A (CD109) Course Detector and CDI35 Course Detector Interface.
General Information FU50 Follow-Up Steering Lever The FU50 Follow-up steering lever features a dial (scale) with 5° rudder angle markings. The rudder will move and stop at the angle selected on the dial. The FU50 has a mid-position indent, buttons for (limited) mode selection, and mode indicators (STBY, FU, AUTO, NAV, WORK, and THRUSTER*). It is designed for indoor and outdoor bulkhead- or panelmounting. Refer to the FU50 manual. * With AP50 Autopilot only.

Operation 2 OPERATION OF THE AUTOPILOT Caution ! An autopilot is a very useful navigational aid, but DOES NOT under any circumstance replace a human navigator.
Simrad AP35 Autopilot A group of user adjustable settings are provided in the AP35 USER SETUP MENU (page 25). The settings allows adjustment of display visibility, selection of heading sensors, navigation and position sources and the ability to select between automatic or manual adjustable sea state filter. Alarms are presented in plain text to alert you of system and external data failure conditions. Alarms include both audible and visual presentations. The alarm listing is on page 91. 2.
Operation 2.3 Follow-Up steering When both the PORT and STBD push buttons are pressed simultaneously the AP35 is set to Follow-Up steering mode and rudder commands can be set by the course dial. One revolution of the dial equals 45° rudder command. The rudder will move to the commanded angle and stop. PORT STBD Follow-Up mode. Commanded rudder angle: 22° to stbd. Rudder angle:12 FU 22 12 Press both buttons simultaneously to activate Follow-Up Use course knob to command rudder angle.
Simrad AP35 Autopilot 2.7 R3000X Remote Control SIMRAD Push buttons for Port and Stbd NFU commands STBY-AUTO STBY/AUTO mode button. AUTO, WORK or NAV mode is when lamp is lit Note! When in AUTO/WORK mode, pressing the buttons will change the set course 1° per push. If you keep the button pressed, it will automatically change the course in increments of 3°/second.
Operation 2.9 Automatic Steering The AUTO mode is used to make the AP35 steer the boat automatically on a set heading. AUTO is always available from any mode or function within the AP35 by a single push on the AUTO button. When the AUTO mode is selected, the AP35 automatically selects the current boat heading as the set course and the current rudder angle to compensate for wind/current. Note ! If Init Rudder “Midship” is selected (see Dockside settings, page 71 the rudder will move to midship (0°).
Simrad AP35 Autopilot 2.10 Automatic Speed selection The AP35 provides two different sets of steering parameters for controlling the response of the boat at different speeds (HI or LO) while in AUTO and NAV modes. The AP35 always selects the HI speed steering parameters when first switched on. This is a safety feature.
Operation 2.12 Navigating with the AP35 The AP35 has the capability to use steering information from an external navigator (GPS, Chart Plotter) to direct the boat to a specific waypoint location, or through a route of waypoints. In the NAV mode, the AP35 uses the heading sensor as it's source of heading for course keeping. The steering and speed information received from the external navigator alters the set course to direct the AP35 to the destination waypoint.
Simrad AP35 Autopilot When operating the AP35 in NAV mode to automatically steer through a route of waypoints, the AP35 will steer to the first waypoint in the route after you accept the first waypoint as the location to steer to. When you arrive at the waypoint, the AP35 will display an alert screen with the proposed new course information displayed. If the required course change is more than 10° you will need to verify that the upcoming course change is acceptable.
Operation 2.13 WORK-mode The WORK-mode is an automatic steering mode to be used under operational conditions different from those normally found when a vessel is in transit on a preset course. Examples are trawling, towing, trolling on one engine, slow speed etc. First Press Second Press W 313 315 WORK ADJ 02 W315 Rudder angle Set course LO WORK ADJ At such incidents some boats may need a rudder off-set when steered by hand.
Simrad AP35 Autopilot 2.14 TURN-mode The AP35 provides special turn features when in AUTO or WORK modes. U-Turn changes the current set course to be 180 degrees in the opposite direction. The user may decide if the U-Turn should be made to Port or Starboard to bring the boat on the new course. U-Turn is activated by a single push on the TURN button. After the single push, the AP35 will continue on the set course until you press either the PORT or STBD button to select the direction to make the U-Turn.
Operation 2.15 Dodging The AP35 also provides the capability for dodging. Dodging is useful in situations where you need to quickly take control of the helm to steer around an obstruction, and then wish to return on the previous set heading after performing the evasive manoeuvre. A quick double press on the TURN/DODGE button activates dodging. When in DODGE mode the course displayed is the current boat's heading, however, the previous set course is remembered by the AP35.
Simrad AP35 Autopilot 2.17 Lock function The "LOCK" function is a safety feature included in the AP35 system to disable all control units except for a single, user selected control unit location. When the "lock" function is in use, no transfer of command may take place; only the "active" control unit stays in command. To enable the "lock" function, make a quick double press on the STBY button.

Installation 4.5 AP35 System Layout Figure 4-1 AP35 System layout with options 4.6 RF300 Rudder feedback The RF300 Rudder feedback unit mounts close to the rudders, and is mechanically linked to the rudder tiller arm or rudder quadrant. Refer to Figure 4-2 for the recommended mounting arrangement. Note that the RF300 transmitter arm has two slots for the transmission link. The slots enable maximum flexibility to provide the 1:1 mechanical linkage relationship.
Simrad AP35 Autopilot Note ! Carefully observe the alignment marks. A rudder feedback alarm may be the result if the alignment instructions as per Figure 4-2 are neglected. Attach the transmitter rod to the RF300. Set the RF300 mounting location to be in accordance with Figure 4-2. The centre of the RF300 should be in line with the centre of the rudder post. Mount the RF300 to a suitable platform using the screws provided.
Installation 4.7 RF45X Rudder Feedback Unit The RF45X is normally installed with the shaft pointing upwards. It can, however, be mounted with the shaft pointing downwards if this is more convenient. The deflection can then be inverted as illustrated in Figure 4-5. An “upside-down” installation will make access to within the unit more convenient as the unit can be opened without moving it from the mounting base. To open the unit, unscrew the two screws at the bottom and remove the cover.
Simrad AP35 Autopilot Electrical connection Use a twisted pair cable AWG20 (0.5 mm2) between the breakout box and the J3xx junction unit. The cable length is not critical but should be kept at a minimum. The cable should be connected to the junction unit according to Figure 4-5. When splicing the cables in the breakout box, crimp the enclosed pins on each wire of the extension cable. Otherwise the wires may be cut off at the terminal point when the screws are tightened.
Installation 4.8 Junction unit The junction unit is designed to operate in a location that provides ambient temperatures below +55°C (+130°F). Note ! The junction units (J3000X, J300X and J300X-40) are not water proof and should be mounted vertically as shown in a dry place between the control unit and the drive unit. Figure 4-6 J3XX mounting Cable connections Use only shielded cables. This includes Mains input, drive units and if necessary for the extension of the RF300 Rudder Feedback cable.
Simrad AP35 Autopilot Grounding and RFI The AP35 system has very good RFI protection and all units are using the Junction Unit as common ground/shield connection. The Junction Unit should therefore have a proper ground connection to the hull. ROBNET cables and other signal cables (compass, feedback, NMEA) should not be run in parallel with other cables carrying RF or high current, such as VHF and SSB transmitters, battery chargers/generators and winches.
Installation Main Board terminals 4.9 Drive unit The relation between drive units, drive unit voltage, input voltage, drive output and interfacing to steering gear are shown in the table below. The AP35 system detects whether a reversible motor or a solenoid is connected and outputs the correct drive signal automatically. Refer to the connecting diagram for the different drive units on page 51 onwards. Installation instructions for the drive units are found in the manual for the individual units.

Installation HOW TO REMOVE PINS: Extraction tool Pull the wire Insert tool in slot Note ! For installations that require special cable length, contact your Simrad distributor for information. 4.11 RFC35 Fluxgate Compass Figure 4-14 RFC35 mounting The heading sensor is the most important part of the AP35 system and great care should be taken when deciding the mounting location.
Simrad AP35 Autopilot If the RFC35 is deck mounted or bulkhead mounted athwart ship with the cable gland pointing aft, little if any offset correction is required. With the cable gland pointing forward a 180° correction is required. When mounting RFC35 on a bulkhead along ship, a +90° or -90° correction is needed dependent on whether it is a port or starboard bulkhead.
Installation • Connect the Robnet connector to the AP35 Control Unit (or GI51 or NI300X if installed), see Figure 4-16. • Alternatively, if there is no free receptacle, cut the connector from cable and connect the wires in parallel with the wires going from junction unit to the control unit (see Figure 4-13). Do not connect yellow and the green wires and ensure that they do not connect with terminal or chassis. the the the the • Select RFC = ROBNET in the Installation : Interface Setup.
Simrad AP35 Autopilot 4.15 S35 NFU Steering Lever The unit is mounted to bulkhead or panel by two screws from the front. The cable is connected to the junction unit according to Figure 4-18. Interchange the port and stbd wires to the screw terminals in the junction unit if necessary to make the direction of the lever movement coincide with the direction of the rudder movement.
Installation 4.17 RI35 Mk2 Rudder Angle Indicator The RI35 Mk2 is designed for flush, bulkhead or bracket mounting, and should be positioned in a location in clear view of the helmsman. Mounting of RI35 Mk2 is identical to the mounting of AP35 Control Unit; refer to page 52. When the location is determined, the cables should be connected to RI35 Mk2 before the unit is mounted. The interconnection cables are screened, and the screen should be grounded in the autopilot junction unit.
Simrad AP35 Autopilot Reversed deflection On installations where the rudder feedback unit is mounted upside down, the deflection of the pointer will be reversed. To make it correct, move the rudder to approximately 10° either way then press and hold the illumination key for 10 (ten) seconds. The pointer will then first travel to zero then continues to the opposite side of the scale confirmed by a 2-second beep.

For heading offset and alignment, see GI51 Manual. 4.31 CD100A Course Detector On some installations the owner may prefer to use the boats own compass. The compass must be fully gimballed and have a flat surface underneath to fit the CD100A.
Simrad AP35 Autopilot 4.32 CDI35 Interface Locate the CDI35 as close to the compass as possible so that there will be no problem finding it in the event of a service. Put the two fixing screws in the slots and secure the unit to the bulkhead. Open the unit to access the screw terminals. Connect the cables as shown on the diagram below. Figure 4-33 CDI35 connection Note ! CD100 has a connector that has to be cut off the cable. 4.

Simrad AP35 Autopilot On new installations, and whenever a control unit, junction unit, or software is replaced in an AP35 system, it is recommended that a MASTER RESET be performed as described in the ISM prior to proceeding with the setup procedure. When using the ISM refer to diagram "Installation settings Menu Flow Chart" on next page.
Installation Language selection The AP35 can present the display in eight different languages: • English, Norsk, Francais, Espanol, Italiano, Nederlands, Svenska and Deutsch. To access the language selection in the ISM: 1. Turn on the equipment and wait approx. 5 seconds. 2. Press the NAV/setup button for about 5 seconds until the display is changed to: INSTALLATION Language English 3. Turn the course dial until the language you wish to use is displayed. 4.
Simrad AP35 Autopilot Type of boat will affect the steering parameters, and the functions available in the autopilot system. Select appropriate boat type and press STBD [>] button. Drive unit voltage selection This menu option requires the installer to set the drive unit voltage to the correct level. The selections are 12V, 24V or 32V and should be set to the voltage specified for your drive unit.
Installation 4. Press the STBY button again if necessary to read the rudder angle display (You may also access the User menu and the SYSTEM DATA menu item to read the rudder angle). 5. Use a flat screwdriver in the slot and adjust the rudder angle to zero degrees on the display. 6. Secure the transmission lever to the shaft and proceed with the ‘Rudder Feedback Calibration’. Note ! If the autopilot presents you with a Rudder Feedback Alarm after turn on, proceed as follows: • Turn the autopilot off.
Simrad AP35 Autopilot Manually turn the helm wheel to port until the rudder stops at maximum port rudder. INSTALLATION Turn rudder max. PORT 039 Adjust? Adjust the displayed angle the same way as for starboard adjustment. (This time you need not correct for wrong side if the Rudder Feedback is upside down). Note ! Rudder zero may still be wrong but will be adjusted later during Sea Trial. Proceed to next menu item by pressing STBD [>] button.
Installation Transition Speed INSTALLATION Transition speed: 00 kn The transition speed is the speed where the AP35 will automatically change the steering parameter set from the HI speed to LO speed parameters, or vice versa. The default setting of transition speed is zero, which requires that steering parameter selection be done manually.
Simrad AP35 Autopilot Initial Rudder When Actual is selected, the autopilot will use the current rudder position as midship reference (bumpless transfer) when switching from Stby to Auto or Nav. (or Dodge). When Midship is selected the autopilot will use zero degrees as midship reference. Hence, the rudder will always move to midship when switching from Stby (or Dodge) to Auto or Nav mode.

Simrad AP35 Autopilot Counter Rudder is the parameter that counteracts the effect of the boats turn rate and inertia. For a short time period it is superimposed on the normal rudder response as provided by the Rudder parameter. It may sometimes appear as if it tends to make the rudder move to the wrong side (counter rudder). The best way of checking the value of the Counter Rudder setting is when making turns. The s illustrates the effects off various Counter Rudder settings.
Installation • Try the Dodge function, the U-turn and the C-turn. • If a Non-Follow Up lever (or handheld remote) is connected, test the mode switching and verify Port and Stbd steering commands of the lever. • Set waypoints into each navigator connected to the system, and verify that the AP35 steers in NAV mode for each NAV source. • Provide the owner with user training. 4.
Simrad AP35 Autopilot 5 MAINTENANCE 5.1 Control unit The AP35 Control Unit will under normal use require little maintenance as the cases are made from seawater resistant aluminium and has a polyester coating to withstand the rigours of an exposed cockpit. If the unit requires any form of cleaning, use fresh water and a mild soap solution (not a detergent). It is important to avoid using chemical cleaners and hydrocarbons such as diesel, petrol etc.

Trouble Shooting 6 TROUBLE SHOOTING An autopilot is a complex system and the performance is dependent of a proper installation and a successful sea trial. In the event of a failure, you will be helped by the AP35 software which contains several test features that will assist you in isolating a probable fault. Audible and visual alarms are given in the event a fault is detected. The audible alarm is reset by pressing any button (e.g. by changing mode from AUTO to STBY).
