Simrad AP25 Autopilot

mounting location. As the heading is displayed on the AP25
Control Unit, the heading sensor can be mounted at a remote
location.
The RC36 rate compass also contains a magnetic heading sensor,
so particular attention must be paid to the location. It can be
mounted on deck or bulkhead, athwartship or alongship and has
a 15 m (99’) cable with a Robnet2 connector. The heading offset
feature in the AP25 will compensate for the mechanical offsets
that may be a result of the selected location and orientation of the
RC36.
If the RC36 is deck or bulkhead mounted athwartship with the
cable gland pointing aft, little if any offset correction is required.
With the cable gland pointing forward a 180° correction is
required.
When mounting RC36 on a bulkhead alongship, a +90° or –90°
correction is needed dependent on whether it is port or starboard
bulkhead.
Note ! Offset correction is performed after the calibration (see
paragraph
4.7).
Find 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 influences such as the engines
(min. 2 meters), engine ignition cables, other large metal objects
and particularly the drive unit. On steel hull boats it should be
mounted 0,75-1 m above the wheel house on a non magnetic
stand.
Use the supplied mounting kit and drill the holes through the
centre of the slots in the sensor or the mounting brackets.
Note ! The compass face plate on the RC36 is the TOP. Never mount it
upside down! Level the sensor as close to horizontal as possible.
