Figure 2-17 Mounting
The heading sensor is the
most important part of
the autopilot system and great care should be taken
when deciding the mounting location. As the heading is
displayed on the control unit, the heading sensor can be
mounted at a remote location.
The compass can be mounted on deck or bulkhead,
athwart ship or along ship. Some of the products
connected to the SimNet network may have a heading
offset feature. This will compensate for the mechanical
offsets that may be a result of the selected location and
orientation of the compass.
If the connected products have no offset feature, the
compass must be deck
with the cable gland pointing back.
Select a location that provides a solid mounting place free
from vibration, and as close to the vessel's centre of roll
and pitch as possible, i.e. close to the water line. It
should be as far as possible from disturbing magnetic
interference e.g. engines (min. 2 meters), engine ignition
cables, other large metal objects and particularly the
autopilot drive unit. On steel hull boats it should be
mounted 0,75-1 m above the wheel house on a non
magnetic stand.
