The different connecting diagrams below illustrate the interface possibilities. See separate installation description enclosed with the units. The alarm voltage is the same as the main supply voltage. 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, to view LED indication of received signals.
It should be installed with the cable inlet and the Robnet connectors facing down. The NIX is not weatherproof, and must be installed in a dry location! Four NMEA ports are available. LF Linear Feedback Note! The rod of the LF is not locked in place in the cylinder. If caution is not exercised it may slip out of its housing and end up over the side, so be careful! The LF is a waterproof feedback unit. It has a mm 11,8" stroke and comes with a special mounting bracket which secures the LF to the cylinder of the existing outboard drive unit.
Center the drives. Loosely secure the LF to the supplied mounting bracket, across the center of the drive unit cylinder. Either cylinder may be used if there is a dual set up. You may mount the feedback in either direction, i. Insert the rod retaining assembly b end plate and retighten this bolt. Secure the feedback rod to the end plate using the two washers and cap nut provided.
Adjust the location of the LF Linear Feedback to allow full travel of the hydraulic cylinder without causing the endplate of the LF hitting the end of the cylinder. Check that the outboard motor can be tilted freely. Tighten all nuts and the mounting bracket. Turn the helm slowly by hand to the stops on either side, making sure that the rod does not bind up in any direction.
Also, clamp cable to allow full engine movement to port and starboard. The mounting hardware provided with this system is meant to interface with Teleflex HC cylinders and Hynautic K7 and K10 Cylinders. If you are attempting to interface to another system the hardware enclosed may not be appropriate! Contact your dealer to obtain the correct mounting kit.
A previous version of the LF has been delivered with an alternative cable with a different color code. The compass must be fully gimballed and have a flat surface underneath to fit the CD Make hole for a 6 mm screw in the bottom of the compass and mount the CD as shown on the drawing.
Secure the 6 mm screw through the centre hole of the CD Make sure the cable does not prevent the compass from moving freely in the gimbals.
To be removed before mounting. Put the two fixing screws in the slots and secure the unit to the bulkhead. Open the unit to access the screw terminals. Cut the CD cable to make a suitable length and connect both cables as shown on the diagram below.
The principle advantage is that manual adjustments that needed to be done on previous models are no longer necessary with the APX. The installation settings must be performed as part of the installation of the APX system. Failure to correctly set the values in the installation settings may prohibit the APX from functioning properly!
No specific action is required to "SAVE" the selected values. Once the value is changed, it is stored until the next time the menu item is selected and changed. Refer to flow diagram on the opposite page for a pictorial view of Installation Settings Menu. Proceeding to the next item when presented with a question is the same as answering NO to the question.
Turn on the equipment and wait approx. Turn the course selector until the language you wish to use is displayed. To access the Dockside settings, turn the course selector clockwise. The options are: Displacement, Planing, Sail.
Type of boat will affect the steering parameters, and the functions available in the autopilot system. The selections are 12V, 24V or 32V and should be set to the voltage specified for your drive unit. Selection of improper voltage level for your drive unit may damage both the drive unit and junction unit even if the protection circuits in the junction unit are activated.
Refer to the drive unit table on page 72 for information. It is not possible to select a higher voltage than the input voltage. The APX system will also automatically detect whether the drive unit is a reversible motor or solenoid operated. To change the voltage selection, rotate the course selector. This function enables you to compensate for any non-linearity in the mechanical transmission between rudder and Rudder Feedback Unit.
Confirm by rotating the course selector clockwise. STBD Adjust? Manually turn the helm wheel to starboard until the rudder stops at maximum starboard rudder. The value shown on the display is the value read by the feedback unit before any adjustment is made.
The arrow indicates to which side the rudder is positioned. If the displayed angle is different from the actual angle, set correct rudder angle on the display by turning course selector clockwise to increase the value or counter clockwise to decrease the value. If the rudder feedback is mounted upside down, the displayed rudder angle may be to the wrong side before you start the adjustment arrow pointing to Port.
PORT Adjust? Manually turn the helm wheel to port until the rudder stops at maximum port rudder. 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. Rudder zero may still be wrong but will be adjusted later during Sea Trial.
Automatic Rudder Test Note! Move the rudder manually to midship position before starting the test. It is important also that if the boat uses power assist steering, that the engine or electric motor used to enable the power assist steering be turned on prior to this test.
Activate the automatic rudder test by turning the course selector clockwise. The APX will issue a series of PORT and STBD rudder commands and automatically verify correct motor direction, and reduce the rudder speed if it exceeds the maximum acceptable speed for autopilot operation.
The default setting of transition speed is zero, which requires that steering parameter selection be done manually. If a GPS, Loran, or external speed log input from Dataline or other instrument systems is connected, it is recommended to set the transition speed to a value greater than 0, to enable the automatic speed selection feature in the APX.
It is recommended that you set the transition speed to a speed that represents the speed where the hull begins to plane, or where you would manually change the parameters from HI to LO. The speed used for the automatic transition is obtained as follows: 1.
If this is a valid source of VHW speed through the water data, then this data is used for determination of when to change parameter sets. The AP will always default to the HI speed steering parameters when the system is first turned on, and with speed data failure.
If manual speed selection occurs the user manually selects HI or LO parameters , the manual parameter set will remain in effect until the AUTO mode is reselected. Rotate the course dial clockwise until the transition speed is set to the desired value in knots. A Master Reset is part of the final test at factory and will reset the memories to factory settings.
Unless you need to clear all stored values during the installation setup procedure, you should not perform a Master Reset. The Master Reset needs a double confirmation to prevent an unwanted reset.
To perform a Master Reset, rotate the course selector clockwise and observe the display; then rotate the course selector counter clockwise. Interface Settings The APX system provides a totally flexible approach to the input of data from optional equipment.
If your system includes connection of external equipment to the NMEA data ports in Junction Unit or NIX, or if the CIX is installed with optional compass units or an optional analog wind vane unit, they must be configured under this menu. This procedure allows you to assign an abbreviated name to identify the type of equipment that is connected to each of the available hardware ports in the AP system.
When you assign a hardware port to an abbreviated name, you are simply telling the APX system that when the user chooses an abbreviated name as a data source it should look to the hardware port assigned to the abbreviated name for the data. It is recommended that upon completion of the ISM that the configuration be recorded in the Interface Setup Table on page To access the Interface Setup items, turn the course selector clockwise.
Assign a hardware port to the name by turning the course selector until the hardware port is displayed. It is recommended that you access the User Setup Menu directly after completing the Interface Setup to select the desired data. Refer to page 34 for details on changing the items in the User Setup Menu. The names may be assigned to other HW ports as per below dependant of the system configuration. It is also recommended that the Interface Setup be performed prior to Seatrial settings.
Confirm by rotating the course dial Clockwise. Rudder zero adjust The adjustment should be made in calm sea and side forces from wind or current should be avoided. Compass calibration This function will activate the compass calibration procedure. Before you begin the compass calibration procedure, make sure you have enough open water around you to make a full clockwise turn with the boat.
Let the boat turn at idle. Begin turning the boat to starboard. Start compass calibration by turning the course selector clockwise. After calibration, check the compass readout against a known reference, other compass or leading line. Compass Offset The compass OFFSET feature allows you to correct for a constant compass heading offset, that may be present as a result of the RFC35 being installed with a lubber line offset or a fixed offset remains after the calibration procedure has been completed.
The value of compass offset is specific to the heading sensor that is selected at the time the offset is entered. For multiple heading sensor offset procedure, refer to separate CIX manual. The offset value can be either positive or negative. A relocation may be needed.
The scaling factors of the parameters are also set automatically as a function of the boat type selection performed in the Dockside Settings menu.
Autotune is an optional procedure that is not required for the APX to function. The APX is preset with steering parameters that should steer most boats in the 30 - 50 foot range and Autotune may not be required if the preset parameters steer your boat acceptably. Recommended speed during Autotune is knots. Autotune should not be performed at planing speed. It is recommended that the Autotune be done in an East or West direction if possible, as these will yield the best balanced parameters.
The Autotune function will take control of the boat and perform a number of S-turns. It must always be performed in open waters with sufficient safe distance to other traffic. The Autotune function may take from 1 to 2 minutes to complete. After the Autotune has been completed the rudder must be controlled manually, as the mode is returned to STBY. When the Autotune has been completed, there should normally be no need for further adjustments.
On certain installations, however, you may want to "fine tune" the parameters after the Autotune due to the special steering characteristic of a specific boat. A boats steering parameters found by Autotune can be looked at and if needed changed under this menu item.
The steering parameters can also be set to values manually instead of performing an Autotune. As a sail boat's steering characteristic is very much dependent of sail trim, the parameters may be optimized manually from values found by Autotune. The values in the table are factory set and listed for information only.
After having performed the Autotune, the values may differ from those listed in the table. It is recommended that you write down the parameters "learned" by the Autotune prior to making any adjustments. The two most important parameters that determine the performance of the automatic steering are Rudder and Counter Rudder. Rudder sets the rudder gain which is the ratio between the commanded angle and the heading error P-factor. 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 figures illustrate the effects off various Counter Rudder settings. New course New course Counter rudder setting too low, overshoot response Counter rudder setting too high, sluggish and creeping response New course Correct setting of counter rudder, ideal response Autotrim standard value is 40 which should work well on most boats.
On sailboats it may be preferable to set Autotrim to zero, to avoid unwanted rudder offset when changing course Rudder Limit should be kept at 20 degrees unless there is a need for more rudder when performing dockside maneuvers. Steer the boat on all cardinal headings in AUTO mode. Start with low and medium speeds to get familiar with the response from the APX. Try the effect of LO and HI speed settings.
Try the Dodge function and the U-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. If the installation is on a sailboat, try the specific sailboat functions using the owner as a consultant on the boats specific steering characteristics when sailing. Be careful to avoid hazardous situations until you gain experience. Provide the owner with user training. Providing user training The user should be instructed in the "basic" operational functions, such as: Turning the system on and off Explain how to change modes explain briefly what takes place in the different modes.
Regaining manual control from any mode. How to take command at an "inoperative" station if applicable. Review how to use a NFU controller if connected. Course change by rotary knob and buttons. Also include Nav. Show the owner where the compass or compasses is mounted and instruct him to keep magnetic items away.
Show where the Mains circuit breaker is. 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. It is advisable at the start of each season to check all connections to the control unit head and cover with Vaseline or WD If the Control unit is not removed from the boat, it should be covered with the white protection cover.
It is advisable, however, at the start of each season to make a visual inspection of the internal and check all connections.
Apply some grease at the ball joints when required RF 4. In the event of a failure, you will be helped by the APX 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.
The visual alarm will remain and alternate with the operating display until the fault has been rectified.
