Alignment for RF45X Rudder Feedback
Unit
The purpose of this procedure is to find
the zero point and make the feedback unit
operate within its active segment. If the
unit operates outside this segment there
will be a feedback failure alarm.
1. Position the rudder amidships.
2. Loosen the two screws that secure the
transmission lever to the RF45X shaft.
3. Turn on the autopilot and wait until
the display shows “SETUP
REQUIRED” (see note below).
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. Use a flat screwdriver in the slot and turn the shaft
180°.
• Proceed from paragraph 3 above.
Rudder Feedback Calibration
This function enables you to compensate for any non-linearity in the
