Chapter 3: Installation 17
If you are fitting an ST60+ Rudder Angle Indicator instrument as part of a system
which includes a SeaTalk autopilot, the transducer must be connected directly to
the autopilot. The ST60+ Rudder Angle Indicator will then act as a slave to the
autopilot.
Rotary Rudder Reference Transducer
Mounting
1. Ensure that the base height of the Rotary Rudder Reference Transducer is such
that it is able to maintain the correct vertical alignment between the trans-
ducer and tiller arm (as shown).
2. Using Rotary Rudder Reference Transducer template (supplied at the rear of
this handbook), mark the centers for the three securing screws at a suitable
location adjacent to the rudder stock.
3. Drill out the three 3 mm holes then, using the three self-tapping screws pro-
vided, secure the Rotary Rudder Transducer in position.
Note:
To ensure precise rudder position indication, the Rotary Rudder Reference Trans-
ducer incorporates a spring to remove any mechanical backlash in the tiller linkage.
