rotate the Rotary Rudder Reference Transducer body to achieve the required
adjustment, then re-tighten the screws.
2. Position the tiller pin within the limits shown. Ideally, dimension ‘A’ should be
5.5 in (140 mm). Secure the tiller ball-pin to the tiller arm using the two self-
tapping screws provided.
Note: Variation within the given limits will not degrade autopilot performance but will
slightly alter the scaling of the ST60 Rudder Angle Indicator display.
3. Cut the threaded rod to length and screw one lock-nut and ball socket onto
each end of the rod.
4. Offer up the rod (with ball sockets) to the Rotary Rudder Reference Arm and
tiller, making adjustments to the ball sockets as required then, supporting the
ball sockets (by means of a suitable wrench) tighten the locking nuts.
5. Press each socket onto its corresponding ball-pin.
6. Move the rudder from side to side and ensure that the linkage is free from any
obstruction at all rudder angles.
Note: If the Rotary Rudder Reference Transducer has to be mounted in an inverted posi-
tion, the connections for the red and green wires at the ST60 Rudder Angle Indicator instru-
ment (or course computer) must be reversed.
