Special applications, Example 2
The AP9 MK3 autopilot is also designed to operate a tunnel bow
thruster, with possibility to set deadband and thruster power in the
second parameter set.
The control signal is the ±10V analogue, generated via the Thruster
Interface PCB.
The shown configuration also includes a main propulsion azimuth
thruster, operated by ordinary ON-OFF solenoid valves.
A special feedback arrangement is required to replace the standard
RF14XU. It consists of a servo potentiometer and a voltage-to-
frequency converter, to facilitate the installation of the mechanical
and electrical part of the feedback system. Contact Simrad for further
