Simrad AP35 Autopilot
58 22083083H
If the RFC35 is deck mounted or bulkhead mounted athwart ship 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 RFC35 on a bulkhead along ship, a +90° or -90° correction
is needed dependent on whether it is a port or starboard bulkhead.
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
influences such as the engines (min. 2 meters), engine ignition cables, other
large metal objects and particularly the drive unit.
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 RFC35 is the TOP. Never mount it upside
down! Level the sensor as close to horizontal as possible.

4.12 RC25 Rate Compass
The RC25 Rate Compass also contains a magnetic fluxgate sensor, which
means you have to take the same precautions at installation as for the
standard RFC35. On steel hull boats, however, it should be installed 1 meter
above the steel deck to obtain optimum performance.
