Horizontal alignment
When viewed from above (as shown in the previous illustration):
• the sensor arm must be between 75 mm (3 in) and 310 mm (12 in)
from the tiller arm
• with the rudder amidships, the sensor arm should be at 90° to the
connecting rod and directly opposite the cable entry point on the
sensor body
• when the rudder moves from hardover to hardover:
•
the sensor arm and the tiller arm must remain parallel to each
other at all times
• sensor arm movement must not exceed +/- 60°: the rudder
position sensor may be damaged if the steering system drives
the sensor arm beyond these limits onto its end stops
Securing the sensor to the boat
Mount the rudder position sensor on a suitable base alongside the
rudder stock and tiller arm:
1. Hold the sensor in place, mark the mounting holes, then remove
the sensor. (If required, use the template at the back of the book.)
2. Drill the pilot holes using a 3 mm ( 1 /
8
in) drill bit.
3. Attach the sensor to the mounting base using the self-tapping
screws supplied (No 8 x 3 /
4
inch, pan-head).
Note: To make minor adjustments to the sensor alignment, loosen the
screws, rotate the sensor body, then re-tighten the screws.
Attaching the sensor to the tiller arm
Attaching the tiller pin to the tiller arm
1. For optimum performance, mount the tiller pin on the tiller arm
140 mm (5.5 in) from the rudder stock.
Note: If necessary, you can fit the tiller pin anywhere between
101 mm (4 in) and 190 mm (7.5 in) from the rudder stock. This will
not affect autopilot performance, but will slightly alter the scaling of
the rudder angle display shown on the control unit.
2. Hold the tiller pin in place on the tiller arm, mark the mounting
holes then remove the tiller pin. You can mount the tiller pin so it
is aligned either along or across the tiller arm.
