Master compass
Select a mounting location where the deck is horizontally, flat
and with little vibration, and where the pitch/roll motion is as
small as possible.
It is also important to select a mounting location with sufficient
space for installation and service. Refer dimensional drawing,
page 72.
1 Locate the compass on or parallel to the vessel’s
horizontal centerline, with the bow indication on the top of
the case pointing towards the vessel’s bow.
2 Use the datum line in the front and back to of the compass
to line up the unit.
- It is possible to compensate for a small mounting offset
by using the heading offset feature as described in
Adjusting True heading, page 53.
3 Remove the four screws holding the compass case, and lift
the case carefully upwards and away.
4 Remove the cable inlet cover.
5 Fasten the compass to the deck with four bolts. The bolts
should be located in the center of the trails for later to be
able to adjust the compass direction when the heading is
tuned in. Refer Adjusting True heading, page 53.
6 Remove strips and foam rubber from the chock absorbers,
together with all strips used for securing moving parts
during transportation.
