30 TYPE 100/300 Operation and Installation Handbook
2.4 Rotary Rudder Reference Transducer
The rotary rudder reference transducer must be connected directly to the
tiller arm to provide accurate rudder position to the course computer. If it
is more convenient, the unit may be installed upside down. However, if
mounted this way, the red and green wires must be reversed at the
course computer.
Mounting
1. Using the self tapping screws provided, mount the rudder reference
transducer on a suitable base adjacent to the rudder stock.

2. Make sure that the base height of the rudder reference transducer
can maintain the correct vertical alignment between the rudder
reference transducer arm and tiller arm (as shown).
• To give the precise rudder position, the rudder reference transducer has
a built in spring to remove any free play in the linkage to the tiller .
• The rudder reference arm movement is limited to ± 60 degrees. Care
must be taken during installation to ensure that the rudder reference
arm is opposite the point of cable entry when the rudder is amidships.
Failure to do this could result in damage if the rudder reference arm is
driven onto its end stops by the steering system.
