General Information 1 GENERAL INFORMATION 1.1 Introduction Congratulations on the purchase of your new Simrad AP50 autopilot system and thank you for selecting what we feel is one of the most advanced autopilot systems available on the market today. Today, Simrad manufactures a complete range of autopilots for all types of vessels, from leisure boats to advanced steering systems for merchant marine vessels.
Simrad AP50 Autopilot While the AP50 may be installed on vessels not needing to comply with the Marine Equipment Directive, those requiring compliance must have one AP50 Control Unit set-up as a “master unit” in order for the installation to be approved.
General Information At the end of this manual, you will find an index and a glossary, which will help you when studying the manual. Other documentation provided with your system includes a warranty card. Note ! The Warranty Card must be completed by the authorized dealer that performed the installation and mailed-in to activate the warranty. 1.
Simrad AP50 Autopilot 1.4 AP50 Control Unit This compact autopilot control for panel, bulkhead- or bracketmounting has a rotary course knob and a large LCD for readout of autopilot data. It also has two RobNet connectors for system interconnection and expansion. 1.5 Junction Units The junction unit in the AP50 autopilot system contains the steering computer, interface circuits to all system components, and drive circuits for the drive unit motor and clutch. Two models, J50 and J50-40, are available.
General Information RF45X Rudder Feedback Unit This rudder feedback unit with T45 transmission link and 2 m (6 feet) of cable transforms the angular travel of the rudder to a digital signal read by the autopilot steering computer. It is to be used on medium to large size vessels. RF14XU Rudder Feedback Unit This unit can replace the RF45X Rudder Feedback Unit in installations where a more rugged construction of the feedback unit is preferred.
Simrad AP50 Autopilot The sensor unit contains two GPS sensors and an inertial element. This unit is to be mounted on the vessel mast. The interface unit contains the main CPU and serial interface with high-speed communication. The display unit contains a LCD for navigation information and buttons for user control and command. The interface unit and the display unit may be mounted on the bridge. Refer to the HS50 manual.
General Information S100 NFU Steering Lever The S100 Non-follow-up steering lever is designed for indoor console mounting and it has a spring-loaded return-tomid-position feature. S35 NFU Steering Lever The S35 is designed for indoor and outdoor bulkhead-mounting and is made of shock resistant polyxymethylene. The lever has a spring loaded return-to-mid-position feature. Its push button with light indicator is used for (limited) mode selection when connected to an autopilot junction unit.
Simrad AP50 Autopilot AD50 Analog Drive The AD50 Analog Drive is designed to provide a control signal for operating an analog rudder in an AP50 system by either analog or proportional ±10V control, or Danfoss PVEM valve. The analog rudder output signal is calculated in the AD50 based on operational mode and heading information received over RobNet from other system units. Set-up from the control unit and errors in the analog rudder interface are to be communicated via RobNet.
Operation 2 OPERATION OF THE AUTOPILOT Caution ! An autopilot is a very useful navigational aid, but it DOES NOT under any circumstance replace a human navigator.
Simrad AP50 Autopilot Buttons Action Single short press: Selects AUTO mode and sets the heading reference. Second short press Sets new heading reference. Short press: Selects NAV mode prompt screen from AUTO mode. AUTO Verifies new course to steer when alert screen is shown (can also use the course knob, see below).

Rotate in User Set-up Adjusts or confirms reading.
Simrad AP50 Autopilot The control unit shown in Figure 2-1 on page 19 can operate as a stand-alone unit in an autopilot system or it can be combined in a multistation system. In a multistation system, command can easily be transferred from one unit to another and units not in control will display "Inactive". The autopilot system may also be disabled from the ships’ steering system with an external switch.
Operation Junction unit model Simrad Software V(ersion) and R(elease) J50 SW V1R2 P05 M00 S000 Power board revision, Main board revision and Self check (SW and HW revisions shown are examples only) After approximately 5 seconds, the system is operative and the unit that was turned on will show the STANDBY mode display. Other units in a multistation system will display "Inactive".
Simrad AP50 Autopilot 2.3 AP50 with MSD50 Stern Drive unit Note ! The information in section 2.3 only applies if your autopilot is driving a Simrad MSD50 Stern Drive. The MSD50 Stern drive unit has a relative feedback signal which needs a zero point setting after the autopilot has been turned on. Refer to the MSD50 manual for further information.
Operation 2.4 Follow-Up (FU) Steering When both the (PORT) and (STBD) buttons are pressed simultaneously, the AP50 will enter Follow-Up steering mode and the course knob may be used to set rudder commands. One revolution of the knob equals a 45° rudder change. The rudder will move to the selected angle and stop. P FU 340.7 Display information: • Follow-Up mode RUDDER • Commanded rudder angle: 3° to starboard 02 • Rudder angle: 2° • The small starboard arrow shows that the rudder is moving.
Simrad AP50 Autopilot R3000X Remote Control (NFU) SIMRAD Push buttons for Port and Stbd NFU commands STBY-AUTO STBY/AUTO mode button. AUTO or NAV mode is when lamp is lit In STANDBY mode, the rudder will move as long as the Port or Stbd button is pressed. In AUTO mode the set course will change 1° each time the button is pressed. Note! If you keep the button pressed, it will automatically change the course in increments of 3° per second.
Operation Note ! NAV STBY AUTO NAV-WORK STBY AUTO-WORK NAV-WORK mode can only be entered from a control unit or AP51 Remote Control Unit. 2.6 Automatic Steering AUTO Mode AUTO AUTO mode is used to make the AP50 steer the vessel automatically on a set heading. AUTO mode is always available from any mode or function within the AP50 by a single push of the AUTO button.
Simrad AP50 Autopilot STBY Press the STBY button to regain manual steering AUTO-WORK Mode The AUTO-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 pre-set course. Examples are trawling, towing, trolling on one engine, slow speed etc. WORK In such situations, some boats may need different settings. By pressing the WORK button, a separate set of steering and turning values will be used.
Operation 2.7 Thruster Steering If the vessel is equipped with a thruster, it can be connected to the AP50 system and the vessel can then be controlled by rudder, thruster, or both rudder and thruster. After connecting a thruster to the autopilot system (see the TI50 manual) the thruster type must be selected under the Installation Dockside menu (see page 126). A thruster icon below the mode index indicates that a thruster is connected to the system.
Simrad AP50 Autopilot Caution ! When operating an On/Off thruster it is important to note that most electrical thrusters have a built in thermal cut-off switch that will shut off the electromotor if it is overheating and reengage it when it has cooled down. The water temperature also affects the running time. The On/Off thruster may only run for a few minutes, and its total running time for a longer period should be limited by increasing the thruster sensitivity value (see page 156). 2.
Operation WP: BWW : Chg : SIMRAD 270° 70° OK? Press NAV RUDDER 340.7 01 Gyro1 The lower left portion shows the compass heading and the lower right portion shows the rudder angle and port direction. NAV SETUP 340° CTS GPS1 XTE 340.7 Gyro1 The upper half of the prompt display shows the name of the next waypoint (WP), the bearing to the waypoint (BWW), and the required course change (Chg) with the direction in which the vessel will turn. .

Note ! STBY (STBY) If the AP50 is connected to a navigation receiver that does not transmit a message with the bearing to the next waypoint, it will pick a Cross Track Error message and steer on Cross Track Error only.
Operation Caution ! If an ECS is selected as a navigator, the course change verification is waved. This is done so the AP50 is capable of following a route in which the radius of the course change is pre-set in the chart system. Users navigating in this mode must use extra caution. Selecting a Different Navigator If you have more than one navigation source connected to the AP50, you may choose any for navigation.
Simrad AP50 Autopilot • Navigation source: GPS1. The boat is located on the starboard side of the track • Cross track error (XTE): 0.023 nautical mile • Compass heading from Gyro1: 340.

If you do not press PORT or STBD within 1 minute, the AP50 will return to AUTO mode and stay on course. The turn rate can be adjusted either before the turn is initiated or during the turn.
Simrad AP50 Autopilot When the "LOCK" function is in use, no transfer of command may take place; only the "active" control unit stays in command. Note ! On a locked control unit, backlight and contrast can be directly adjusted through the course knob. STBY STBY 340.7 Gyro1 RUDDER To enable the "LOCK" function, quickly double-press the (STBY) button on the “active” unit.
Operation To unlock the locked remote units, you have to take control from the master unit by quickly double-pressing its (STBY) button. STBY 2.13 External system selection 340.7 Gyro1 Disengaged RUDDER 02 An external system selector can be used to change from automatic to manual steering and vice versa (refer to IMO resolution MSC.64 sec.4). The selector switch must adequately indicate which method of steering is in operation at any given moment.
Simrad AP50 Autopilot Adjustment is local to the control unit you adjust. At high temperatures, not all steps are available due to automatic temperature compensation. Steering function (only available if Thruster is selected in the Installation Dockside Menu, see page 126). Select between the following steering functions: The boat is steered by the rudder; by the thruster; or by a combination of the rudder and the thruster, dependent on the selected mode.
Operation AUTO Mode A 341° CTS 340.7 Gyro1 SETUP Move : Adjust : , Backlight Contrast Steering function Rudder Seastate AUTO Rudder 0.50 Count rudder 1.40 Backlight Same procedure as in STANDBY mode. Contrast Same procedure as in STANDBY mode. More Steering Function (only available if Thruster is selected in the Installation Dockside Menu, see page 126). Same procedure as in STANDBY mode.
Simrad AP50 Autopilot Rudder Rudder sets the rudder gain, which is the ratio between the commanded angle and the heading error (p-factor). The default value depends on the boat length. The value (ranging between 0.05 and 4.00) is determined during Sea trial (see page 140), but can easily be adjusted in the User Set-up menu. Counter Rudder Counter Rudder is the parameter that counteracts the effect of the boat’s turn rate and inertia. The default value depends on the boat length.
Operation Thruster Sens (only available if Thruster is selected in the Installation Dockside Menu, see page 126). The Thruster sensitivity determines how many degrees the vessel must deviate from the set course before a thruster command is given. As the vessel deviates from its heading, the thruster will push the vessel back. A higher value will reduce the thruster activity and extend the lifetime, especially for on/off thrusters.

Installation 4 INSTALLATION 4.1 General This section provides detailed information required to properly install the AP50 Autopilot system.
Simrad AP50 Autopilot 4. Set the language (see page 120) 5. Select the dockside settings and perform tests (see page 119) a) Master operation b) Boat type selection c) Boat length selection d) Drive unit voltage selection. e) Rudder calibration f) Automatic rudder test g) Rudder limit h) Rudder deadband i) Thruster type (optional) 6. Interface set-up for Junction Unit, GI50, NI300X and CI300X (if installed; see page 126) 7.
Installation 4.4 Determining System Configuration It is important to become familiar with the configuration of the system prior to beginning the installation. The AP50 Basic system is shown in Figure 1-1 on page 13 and an extended system is shown in Figure 4-1 on page 73. Pay particular attention to the junction unit/drive unit combinations on page 89 and the junction units chart on page 14.
Simrad AP50 Autopilot 4.6 RF300S Rudder Feedback Unit (For small to medium size vessels) The RF300S 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 on page 75 for the recommended mounting arrangement). Note that the RF300S transmitter arm has two slots for the transmission link. The slots enable maximum flexibility to provide the 1:1 mechanical linkage relationship.
Installation Figure 4-2 RF300S Rudder Feedback Unit Mounting (019356) Note ! Due to space limitations, it may be necessary to cut the length of the transmitter rod to move the RF300S closer to the rudderpost. Tighten the mounting screws for both the RF300S Rudder Feedback Unit and the transmitter rod ball joint.
Simrad AP50 Autopilot 4.7 RF45X Rudder Feedback Unit (For medium to large size vessels) The RF45X Rudder Feedback Unit is normally installed with the shaft pointing upwards. However, it can be mounted with the shaft pointing downwards for increased convenience. The deflection can then be inverted in the AP50 software or as illustrated in Figure 4-5 on page 77. An “upside-down” installation will make access to the unit more efficient as it can be opened without moving it from the mounting base.
Installation Electrical Connection Use a twisted-pair shielded cable, 0.5 mm2 (AWG20), between the breakout box and the J50 Junction Unit. The cable length is not critical but should be kept to 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 to avoid cutting off the wires at the terminal point when the screws are tightened.
Simrad AP50 Autopilot Figure 4-6 RF45X Connection to RI9 Rudder Angle Indicators and RI35 Mk2 (optional) The above connection diagram shows how to connect an RI9 Rudder Angle Indicator to a system with RF45X Rudder Feedback Unit. For connection of RI35 Mk2 Rudder Angle Indicators only, refer to the RI35 Mk2 manual. This connection gives full functioning indicator(s) also with the autopilot switched off.
Installation Mechanical Alignment The purpose of this procedure is to find the zero point and to allow the feedback unit to operate within its active segment. If the unit operates outside this segment, there will be a feedback failure alarm. ve Ac ti ent gm se 1. Position the rudder amidships. 2. Loosen the two screws that secure the transmission lever to the RF45X shaft. Fe edb ack failure zone Slot 3.
Simrad AP50 Autopilot 4.8 RF14XU Rudder Feedback Unit Mechanical mounting Before installation check that the alignment mark on the mounting plate agrees with the mark on the shaft. Bring the rudder to Midships position. The feedback unit should be mounted on a plane surface and secured by bolts through the three holes in the mounting plate. It should be linked to the rudder in accordance with Figure 4-7. It is important that the linkage is linear, i.e. the A-a and D-d are pairs of equal length.
Installation The feedback unit has an external ground terminal an must have a proper ground connection to the hull. The grounding wire should be as short as possible and at least 10 mm wide. The RF14XU can be powered either from the rudder angle indicator supply (19-40V DC) or directly from the autopilot junction unit. If a rudder angle indicator is connected, the RF14XU is powered from the rudder angle indicator supply.

Use the same supply for RI35 Mk2 as for the autopilot. The connection shown below gives full functioning indicator(s) also with the autopilot switched off. To have the indicator(s) switched off with the autopilot, connect indicator(s) and rudder feedback supply+ to J50 Vbat+ instead of J50 Supply+.
Simrad AP50 Autopilot Final check After installation, the cable glands must be sealed with silicon to prevent water from seeping in. Also apply silicon grease to the gasket between the bottom and top cover. On the inside of the feedback unit cover, a piece of moisture protecting sponge is attached. The sponge produces a corrosion preventive gas, and to increase the efficiency of the gas the cover must be kept tight.
Installation 4.9 J50 Junction Unit The J50 Junction Unit is designed to operate in a location that provides ambient temperatures below +55°C (+130°F). Note ! The junction units (J50 and J50-40) are not waterproof and should be mounted vertically, as shown in Figure 4-11, in a dry place between the control unit and the drive unit. Figure 4-11 J50 Junction Unit Mounting Cable Connections Use only shielded cables.
Simrad AP50 Autopilot Grounding and Radio Frequency Interface (RFI) The AP50 system has excellent radio frequency interference protection and all units use the junction unit as a common ground/shield connection. The junction unit must therefore have a proper ground connection to the hull. RobNet cables and other signal cables (i.e.
Installation J50-40 Power Board Terminals Main Board Terminals System Select The “System select” (Sys. Sel.) input signal of the J50 can be used to alternate between the boat’s own steering and the autopilot system from an external system selector (refer to IMO resolution MSC. 64 sec. 4). A ground on TB14 Sys. Sel. will force the system into Disengage mode.
Simrad AP50 Autopilot External Alarm (Non Wheelmark System) The external alarm circuit has an open collector output for an external alarm relay or buzzer. The alarm voltage is the same as the main supply voltage. The maximum load on the external alarm output is 0.75 ampere. Figure 4-13 External Alarm Connections (Non Wheelmark System) External Alarm (Wheelmark System) Note ! Wheelmark installation requires separate monitoring of power failure.
Installation 4.10 Drive Unit Installation The relation between drive units, drive unit voltage, input voltage, drive output, and interfacing to steering gear are shown in Table 4-2 and Table 4-3. The AP50 system detects whether a reversible motor or a solenoid is connected and outputs the correct drive signal automatically. Refer to the connecting diagrams for the different drive units on pages 91 through 93. Installation instructions for the drive units are found in the manuals for the individual units.

Installation GI50 Gyro Interface The GI50 Gyro Interface is required when a gyrocompass with geared synchro or stepper signal output is connected to the AP50. The GI50 is also required when a speed log signal with 200 pulses/NM is connected to the system. All cable conductors are terminated in screw terminals on the GI50 PCB. For cabling and connections, see Figure 4-39. Figure 4-39 GI50 Gyro Interface Connections There are also three plug-in jumpers on the PCB, one for each phase.
Simrad AP50 Autopilot The potentiometer VR1 is factory set to a reference voltage of 2.5V, and should not be readjusted. Power Turn-on After power turn-on, verify that the LED D8 is lit. This indicates that the regulated 5V is OK. If step-signals are connected, observe if the LED’s D1, D2 and D3 are lit. If so, pull out the plug-in jumpers and insert them in the vertical direction. The LEDs D5, D6 and D7 shall turn on and off in a Gray-code sequence when changing the gyro heading.
Installation NI300X NMEA Interface Unit The NI300X NMEA Interface Unit is normally installed inside of a console or locker close to navigation receivers, radar, and instruments to keep the cables short. The unit does not have controls that need to be operated during installation or use, but you should be able to take the lid off for inspections and to view LED indication of received signals. It should be installed with the cable inlet and the RobNet connectors facing down.
Simrad AP50 Autopilot The NI300X NMEA Interface (expansion) Unit is designed for installations in which more NMEA lines have to be tied into the system. Four NMEA ports, which are identical in hardware and software, are available and can be connected as desired.

Software Set-up Procedure 5 SOFTWARE SET-UP PROCEDURE 5.1 Description of Installation Set-up The design of the AP50 includes advanced features that have simplified the installation and set-up of an autopilot. The principle advantage is that the manual adjustments that needed to be made on previous models are no longer necessary with the AP50. The Installation Set-up must be performed as part of the installation of the AP50 system.
Simrad AP50 Autopilot stored in the memory of the AP50 system. No specific action is required to save the selected values to memory. Once the value is changed, it is stored until the next time the menu item is selected and changed. • The Installation Set-up is considered global (except language), which enables the values to be available to all control units in the system. • The values in the Seatrial Settings are dependent on the successful completion of the Dockside Settings.
Software Set-up Procedure • Exit the Installation Menu by pressing STBY, AUTO or NAV buttons. On new installations, and whenever a junction unit or software is replaced in an AP50 system, it is recommended that a Master Reset be performed as described under SERVICE in the Installation Menu (see page 147) prior to proceeding with the set-up procedure.

Software Set-up Procedure Master Operation DOCKSIDE Master operation Yes Boat type Displacement Boat length --Drive unit voltage --Rudd feedb cal STBD --Rudd feedb cal PORT --- For vessel that comply with the European Marine Equipment directive, one control unit must be set for Master operation, if more than one control unit is connected. The other unit(s) is then automatically set as a “slave”. The system can only be switched off from the master unit (see also page 37).
Simrad AP50 Autopilot Refer to the drive unit tables on pages 89 and 90 for information. The clutch/bypass voltage is automatically set to coincide with the drive unit voltage. During the rudder test, the AP50 system will also automatically detect whether the drive unit is a reversible motor or whether it is solenoid operated. To change the voltage selection, rotate the course knob. Note ! The Drive unit voltage setting does not apply when operating solenoids on a continuous running pump/steering gear.
Software Set-up Procedure Adjust the displayed angle the same way as for starboard adjustment (if the rudder feedback unit is upside down, you need not correct for the opposite side this time). Note ! If no adjustment has been made to the display readout (i.e. not turning the course knob), the AP50 will set the physical stop to 45°. “Max. rudder limit” will be set to 2° less. Note ! Rudder-zero may still be inaccurate and should be adjusted later during sea trial.
Simrad AP50 Autopilot Rudder Test (Not applicable for analog drives) Note ! Bring the rudder manually to midship position before starting the test. If the boat uses power-assist steering, it is important that the engine or electric motor used to enable the power-assist steering is turned on prior to this test.
Software Set-up Procedure Set Rudder Zero DOCKSIDE Set rudder zero --- Rudder limit 10° Thruster ---- This setting is only shown when analog rudder is used for steering.

Simrad AP50 Autopilot Manual Tuning If the boat steers satisfactorily, there is no need to perform the Manual or Automatic tuning. The two most important parameters that determine the performance of the automatic steering are Rudder and Counter Rudder. These parameters have already been automatically set in the Installation Dockside menu as scaling factors of the boat type and boat length. These settings may also be accessed at any time in the User Setup menu (see section 2.
Software Set-up Procedure While at cruising speed, adjust the Rudder value by turning the course knob until the autopilot keeps the boat on a steady course.

Make a 90° course change (CTS) by rotating the course knob and observe the transition to the new set course.
Simrad AP50 Autopilot Selecting the boat type and length has set default values for these parameters (Installation Dockside menu). Before doing any parameter tuning, check if the boat steers satisfactory with the default setting (can be checked as described under Manual Tuning or by normal Auto steering). Recommended speed during Automatic tuning varies with the type of boat, but it should not exceed 10 knots.
Software Set-up Procedure Speed Response To make this adjustment you need speed input from either SOG or Log. The Speed response adjusts the relationship between speed and amount of rudder, with lower speed requiring more rudder. This adjustment should be done at slow speed as follows: For displacement and planing boats, steer at minimum operating speed.

Advanced Settings When operating in “Continuous” mode, the thruster gain setting determines the power from the thruster versus heading error. For higher values, the power increases with the same error signal. If the vessel tends to oscillate around set heading, the value should be decreased. If the vessel has a slow approach to set heading, the value should be increased. When operating in “Adaptive on/off” mode, the setting determines the fixed power from the thruster. Higher value gives more power.
Simrad AP50 Autopilot Thruster hyst (Only applicable for Continuous and Danfoss thrusters) When applying a command signal to a proportional valve, a certain amount of deadband may occur, dependant on the directional change of the command. Therefore, a certain “extra” menu-adjustable command signal is generated and either added or subtracted to the command signal in order to compensate for the deadband. Hence the command signal gives the required power without the “loss of deadband signal”.

Maintenance 7 MAINTENANCE 7.1 Control unit Under normal use, the AP50 Control Unit will require little maintenance. The case is made from seawater resistant aluminum and it has a polyester coating to withstand the rigorous conditions of an exposed cockpit. It is recommended that units kept clean of salt, since salt will corrode metal over time. If the unit requires any form of cleaning, use fresh water and a mild soap solution (not a detergent).
