WARNING

NOTICE
(page 2)
Mounting Considerations
The sensor must be installed parallel to the tiller arm while the
À
rudder is amidships.
The distance from the rotation axis of the tiller to the ball-joint
Á
assembly must be the same as the distance from the rotation axis
of the sensor to the ball joint assembly.
The sensor and rudder rotation axes must be aligned.
Â
The maximum range of travel from stop to stop is 140° (70º from
Ã
the center position to each stop). Exceeding this range may result
in damage to the sensor.
The rod that connects the sensor to the tiller arm is 11.8 in. (300
Ä
mm) long, and can be shortened if needed.
The rod should be level when connected to the sensor and rudder.
If a perfectly level installation is not possible, the rod must be
installed within +/- 5º off level in order to function correctly.
The rod should be installed perpendicular to the tiller arm and
Å
sensor, using the second hole from the tip of the sensor for the ball-
joint connector.
Although the second hole is preferred, the other holes may be used
if necessary for the installation location.
Connection Considerations
• This sensor can be connected to a compatible Garmin
autopilot system with a 12-pin rudder feedback connector.
• The cable connected to the sensor is 78 in. (2 m) long.
◦ If needed, extension cables for the sensor are available
from your Garmin dealer.
◦ Do not cut the sensor cable to extend or shorten it.
Installation Procedures
Installing the Sensor
