Simrad AP26 and AP27 Autopilots

mounting location. As the heading is displayed on the 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 autopilot 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 Note !).

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.
