ComNav 1101 Autopilot INSTALLATION 4 - 11
RAI Signal/Return
Terminals 19 and 20 are used to drive up to three ComNav Rudder
Angle Indicators (RAls). Multiple RAls must be wired in series.
If all the indicators move to port when the rudder moves to
starboard, reverse the connections to these terminals. If only one
indicator moves to port when the rudder is moved to starboard,
reverse the connections on the back of that particular RAI.
A ZERO ADJUST potentiometer is supplied on the Distribution Box
Circuit Board. Use this potentiometer to ensure that all RAls read
zero degrees when the rudder is in the dead-ahead position.
