Control dimensions
ï It is important to ensure that the dimensions (refer to the illustration)
are within the specified limits.
ï The tiller and transducer arms must be parallel to each other.
ï With the rudder amidships, the transducer arm should be opposite
the cable entry and at 90∞ to the connecting bar.
ï Minor adjustments can be made by slackening off the retaining
screws and rotating the transducer body.
Installing the rudder reference transducer
1. The tiller pin must be within the limits shown in the previous
illustration.
2. Dimension A should (ideally) be 140†mm (5.5†in). However,
changes this within the limits shown will not degrade the autopilot
performance, but will slightly alter the scaling of the rudder angle
display.
3. Secure the tiller pin to the tiller arm using the self-tapping screws
provided.
4. Cut the threaded rod to the required length and screw on the lock
nuts and ball pin sockets.
