Position:
The compass position is the most important item in the installation of the
autopilot. Good course holding is dependent on the compass being free
from magnetic interference.
As the compass has no moving card, it is not necessary for the compass
to be mounted low in the vessel. This can be a place of high magnetic
interference and should be avoided. However,
a position where
excessive roll is experienced, such as the top of a mast, should not be
used.
The compass is weatherproof, not waterproof. A position not open to the
elements should be selected. It can be mounted on top of a flat surface,
on a bulkhead or from the deck head.
NOTE:
Check other side of bulkhead for materials, which
may cause magnetic interference.
Wiring:
The cable leading from the compass / processor must be connected to the
COMPASS
socket on the AP46. Do not run the compass cable with
other cables on the vessel. The compass is supplied with a standard 5
metre length cable.
Magnetic Effect:
Interference from any iron or steel can cause degraded operation of the
compass unit. To prevent this occurring a minimum distance of 1 metre
(3 feet) should be kept from any steel or other ferromagnetic materials.
This includes speakers and radios with internal speakers.
