Maintenance 20221586B 89 Rudder Feedback Calibration Make sure the RF300 is installed a nd aligned as pr. instruction in section 3.6 (or eventually section 3.27 for LF3000). This function enables you to compensa te for any non-linearity in the transmission between the rudder and the rudder feedback.
Simrad AP26 and AP27 Autopilots 90 20221586B Rudder Test Note ! If the boat uses power assisted st eering, it is important that the engine or electric motor used to enable the power assist steering be turned on prior to this test. Bring the rudder manually to mids hip position before starting the test.
Maintenance 20221586B 91 Test of LF3000/LFI3000 Mk2 feedback 1. Align engines to centre position; “zero rudder”. 2. Rev engines to 3-4000 rev/mi n and observe the rudder angle indicator on the autopilot, a 2° change in the reading should be accepted.
Simrad AP26 and AP27 Autopilots 92 20221586B Rudder Deadband The rudder deadband function is adaptive and is continuously operative. It prevents the rudder from hunting and the adaptive function optimizes the deadband to the speed of the boat and the pressure on the rudder.
Maintenance 20221586B 93 Minimum wind angle (NORMAL) The ‘Minimum wind angle’ is the minimum apparent wind angle that will keep the sails well shaped and give an acceptable thrust. This parameter will vary from boat to boat. The ‘Minimum wind angle’ applies in the tack-prevent function.
Simrad AP26 and AP27 Autopilots 94 20221586B Tack time (RACING) When performing a tack in WIND-mode, the rate of turn can be limited. This will give single handed sailors time to handle the boat and the sails during a tack.
Maintenance 20221586B 95 4.5 Interface Settings Sets the format of the clock/data output for radars connected to the Autopilot Computer. Step to the Inte rface part of the Installation Menu. Turn the course knob clockwise to access the Interface Setup items.
Simrad AP26 and AP27 Autopilots 96 20221586B 4.7 Sea Trial Caution ! The Sea Trial must always be performed in open waters at a safe distance from other traffic. The Sea-trial menu can only be acc essed if the Dockside Settings are completed and confirmed.
Maintenance 20221586B 97 Set Rudder zero This adjustment should be made in calm sea and side forces from wind or current should be avoided. • Bring the boat up to cruising speed, and head directly into the wind. • If the boat has twin engines, synchronize the engine RPM's.
Simrad AP26 and AP27 Autopilots 98 20221586B Compass calibration This function will ac tivate the compass calibration procedure for Simrad compasses connected to Robnet2 and the Autopilot Computer terminals (HS).
Maintenance 20221586B 99 4. When the calibration is completed, (after having made approximately 1 1/4 turns), it will be confirmed by the display reading “Confirmed”. Compass deviation The heading from a magnetic head ing sensor will normally have a deviation when compared with the actual direction of the earth’s magnetic field.
Simrad AP26 and AP27 Autopilots 100 20221586B Compass Offset After calibration, also check the compass readout against a known reference, a compensated compass or a bearing. If the reading has a fixed offset, proc eed to next menu item by pressing STBD button or return to STANDBY mode by pressing the STBY button.
Maintenance 20221586B 101 Wind Offset Note ! This offset only applies if you have a wind transducer directly connected to SimNet (IS12TW) or a wind transducer that outputs data on NMEA2000 format. The Wind Offset feature allows you to correct for a fixed wind angle offset.
Simrad AP26 and AP27 Autopilots 102 20221586B Depth Offset Note ! This adjustment only applies to “smart” depth transducers that outputs depth on NMEA2000 format. NMEA0183 sentence ‘DPT’ contains offset and the dept h reading is from the surface.
Maintenance 20221586B 103 It also is recommended to perform the Automatic tuning steering East or West, as this will yield the best balanced parameters. Note ! After the Automatic tuning has be en completed the rudder must be controlled manually, as the autopilot has returned to STBY mode.
