! Set up of the Autopilot Initial Operation Before going through this chapter, you should be familiar with "Display Configuration" on pages 26 .. 28 HDG WIND AP-OFF Rudder Angle LED visible! NAV The DRIVEBOX must be powered and connected to the bus. Make sure there is no second Drivebox or FADEC- Box connected to the bus at the same time, when viewing the configuration! Verify the rudder angle LED is lit in the lower half (3 to 9 o'clock), before proceeding (1 LED = 3 degrees). 1. Select Autopilot Configuration "-AP-" on any Autopilot Display (di=01) or on a Compass-Autopilot Display (di=02). 2. Briefly press left or right button (shows A0) 3. Move rudder manually into center position and rotate the sensor shaft manually through 360 degrees, until the rudder LED stands at 6 o'clock. Note: there might be a second shaft position with the LED in the middle, but the LED would not move gradually, when turning the shaft. Use only the "good" shaft position where the LED can be moved gradually. Then lock the sensor shaft to the rudder with its arresting screw. 4. Rudder sense: use A0:00, move rudder manually to port (for a left turn!) and observe rudder LED also moving left. In case the LED moves the opposite way, set A0:01. Take a note of the correct setting. Remark: one LED corresponds to three degrees rudder angle. 5. Attention: the rudder will move under power during the following step! Be prepared to press the "OFF"-button immediately if the rudder moves towards either end. Exit the setup mode and press the HDG button on the autopilot display and modify the selected heading by 2 degrees, or if you have a SERVO steering wheel with an OFF button, rotate it to the middle and press SERVO. If the rudder moves to either end, press the "OFF" button immediately and switch off the power to the DRIVEBOX. In case of a reversible drive motor or in case of Servo Valves, reverse the leads at terminals 7 and 8 of the DRIVEBOX; for a continuous running pump and a proportional valve, reverse the leads for the valve at terminals 2 and 4 of 22 the DRIVEBOX. For Danfoss-Valves modify A4* (0 or 1). Switch on power (again) and repeat step 5. 6. Adjusting the rudder travel limits: Put your rudder amidships, then engage the autopilot in heading mode. Modify the selected heading by 12 degrees right or left (or apply full deflection on the Servo Wheel in "SERVO" mode, if there is one installed). If the rudder reaches the mechanical stop, reduce A6 to a lower value. If however the rudder does not come near the stops, increase A6 if necessary up to its maximum value of A6=28. Usually there is a slight difference between the left and right side. The rudder sensor mid position should be adjusted mechanically so as to have the boat running straight with the SERVO wheel centered. It can also be adjusted within small limits by modifying A_. Setup Parameters Select AP configuration (as shown to the left) There are two sets of parameters. Selection of the set is done by A9. A0:00 (00 or 01) Rotational sense of the rudder angle sensor. See to the left. A1:00 (00 or 01) Number of the Autopilot Drive- Box. In case of two independent rudders, number 00 must be assigned to port and 01 to the STBD Drive-Box. With Danfoss proportional valves, the idle signal can be adjusted by A1 within 1%. A2:00 Single rudder or two parallel rudders or Jet- and Voith-Schneider Drives. No spreading and no inverse motion. A2:01 Single Jet-Drive with Bow Thruster. A2:02 One or two straight shafts with Bow and Stern Thrusters. In Docking-Mode rudders are spread and rudder motion is inversed at the reversing engine. A2:03 Two separately steered drives (propellers). Rudder motion always inverse at the reversing drive. Spread rudder angles in Docking-Mode. A3:01 automatic heading dead band 01=ON. The width of the dead band is determined from actual boat movement under present sea conditions. The dead band leads to less rudder motion with only slightly less steering accuracy, which is desirable for power saving on yachts and a less nervous helm on boats with mechanical steering. A4:08 (05..31) upper limit for rate of turn under autopilot (degrees per second heading change). Warning: limit NOT applied in LAND-Mode!
A5:05 a) Reversible Pump: This function is for current saving of a Bypass valve. A5=05 gives the lowest current (16% of the nominal value). For no reduction set A5=17. A too small current bears a risk for the valve falling open. b) Direct driven Proportional Valve: Minimum rudder speed is set by A5. A5=02 results in 20% minimum valve current, A5=17 sets minimum current = 100% (= maximum). c) with switch over valve or current regulated servo valve: A5 has no meaning. d) with voltage controlled proportional valve (Danfoss): A5=08 sets the "flow zero point" signal. A6:20 (05...28) Rudder travel limit under command of the Drivebox. See on the left side, for setting up. A7:13 (06...31) Magnitude of rudder deflections for heading corrections. The gain should be set as high as possible, to enable powerful rudder deflections, if needed. However a too high gain could result in heading oscillations, when the rudder drive is slow to follow large rudder commands (not to be confused with quick rudder oscillations, see A9) A8:00 Terminal 1-4: Terminal 7-8: 00 Bypass/Clutch revers. AP-Drive 01 -- -- 02 Cool.Fan (1-2) revers. AP-Drive 03 Bow Thruster revers. AP-Drive 04 AP-Valves L/R Bow Thruster 05 Stern Thruster revers. AP-Drive 06 AP-Valves L/R Stern Thruster 07 Bow Thruster Stern Thruster 08 -- Bow Thruster 09 Stern Thruster -- 10 Bow Thruster -- 11 -- Stern Thruster 12 Stern Thruster Bow Thruster A9:05 a) (01...10) Stopping distance of the rudder drive at full speed. Faster drives need higher numbers. Try the lowest possible number which is not resulting in quick rudder oscillations. Note: rudder oscillations are not to be mistaken for heading oscillations and may be present with the vessel moored in port, when the autopilot or servo steering is on. b) A9 is not applicable for Servo Valves. c) A9=00 temporary setting for A0*..A8* AA:12 (06..50) Insert here the maximum boat speed in knots. Rudder gain will be reduced linearly with increasing log-speed (or GPS-speed), so as to bottom out at 50% at the maximum inserted speed. 23 A_:50 (40...60) The rudder center position can be adjusted (up to +/- 2 degrees) during installation. A higher number turns the rudder to starboard. Ac:00 Ac=01 gives automatic intercepts of the programmed track in NAV mode. Ac=00 offers the freedom (and responsibility) for choosing a suitable intercept angle. An automatic intercept will nevertheless start, when the cross track error is less than 0,030 NM. A-:00 sets NMEA output from the Drivebox: A- =00 .. Test data out (ASCII term.) A- =01 .. Set up flux gate HS8000 A- =02 .. HDM and VHW out (8 Hz) A- =03 .. VHW out (8 Hz) A- =04 .. test heading instead compass A- =05 ... CAN-Bus splitter for dual AP Second group of parameters A0*.. A8* They are not identical to A0 .. A8. They represent a different set of parameters. The asterisk is not shown on the display unit, it is only used here for explanation. A0*.. A8* are displayed, when A9 has been set to zero previously. Otherwise A0 .. A8 will be visible. A0*:00 Standard setting is 00. Only with proportional valve set A0*=01. A1*:00 Set A1*=00 for one single autopilot or two parallel autopilots on two unconnected rudders. Set A1*=01 for two alternating autopilots or two parallel APs on the same rudder (hydraulic system). A2*:00 Set A2*=00 when the rudder angle sensor is connected to the Drivebox. Set A2*=01 when the rudder angle sensor is connected remotely to the CAN-bus, for example to a display unit. A3*:00 Type of rudder sensor: A3*=00 for 90- degree potentiometer. A3* must be set to 01 for 340-degree rudder sensor (requires Drivebox 40L or 08L hardware). A4*:00 Only for two pumps working on the same hydraulic system (assisting each other), set A4*=01. With Danfoss valves, use A4* to reverse the output signal. A5*:00 Set A5*=01 for voltage controlled (Danfoss) proportional valves. A6*:00 (0..16) Basic spread angle of two separately steered drives in Docking-Mode. A7*:00 A7*=01 enables the Docking-Mode without the FADEC system installed A8*:00 A8*=01 makes AP1 (port drive) a permanent SLAVE, even when AP2 (stbd drive, the master) is OFF. The manual steering system should be connected only to the starboard drive.
