    General The RI9 is manufactured in non-corrosive aluminum with a non- reflective black finish. It is designed to operate from both voltage and current signals. The RI9 can also operate from the earlier Robertson "Standard" rudder feedback units. The indicator is made in standard modular size (144x144 mm) to match the standard of the Simrad autopilots.

  • Page 14: Maintenance

    Simrad RI9 Rudder Angle Indicator Maintenance Simrad rudder indicator equipment will need no special attention besides replacing illumination bulbs (See Fig. 1-12 for location of bulbs). It is, however, essential that the mechanical linkage between the rudder stock and the shaft of the rudder feedback unit is regularly checked and maintained in good condition to avoid misalignment.

    The frequency section generates a variable frequency signal with 3400 Hz as midposition reference. This section is only used if a Simrad autopilot is connected to RF14XU. The signal varies at a rate of 20 Hz/degree, increasing when the rudder moves to port and vice versa.

    Instruction manual Other rudder angles The RF14XU is normally delivered for ±45 degrees rudder angle (violet, brown and pink leads are not connected). For ±60 degrees, connect brown lead to terminal 10. For ±70 degrees, connect pink to terminal 10 and for ±90 degrees, connect the violet lead to terminal 10.

    Simrad RI9 Rudder Angle Indicator Adjustments After having tightened all mechanical parts and connected all cables, the following adjustment must be carried out: 1. Check that the rudder is set to midship position. 2. Measure the voltage between "U" and "+", respectively "-" on the RF14XU terminal board.

  • Page 27: Rf45X Rudder Feedback Unit

    Instruction manual RF45X RUDDER FEEDBACK UNIT General The RF45X is a medium duty rudder feedback unit. Mechanically it is identical to it’s predecessor RF45, therefore it is a repairable rather than a potted throw away item. Electrically it outputs a frequency (pulse width modulated) signal that matches with the J3XX input (AP35/AP50), but it can also output a frequency signal (selectable via internal jumpers) that matches with AP45 and AP9 Mk3.
