Robertson AP45 Autopilot
Installation
Illumination
The scale is illuminated by internal LED's. The illumination is turned on and
adjusted in three steps by the front panel key pad.
Zero adjust
Follow the instructions on page 6-1 to zero adjust the rudder feedback.
There may be a difference in the RI35 and the autopilot reading. This is normal
because the autopilot zero adjust compensates for drag caused by the hull, flaps etc.
If you prefer the readings to be aligned, then put the rudder amidships using the
RI35 as reference, and then zero adjust the autopilot.
Reversed deflection
On installations where the
feedback
unit
is
upside down, the deflection of
the pointer will be reversed. To
make it correct set SW1 on the
PCB to the opposite position.
The first production lots did
not have the SW1 switch.
Instead interchange the brown
and white wires going from the
instrument
housing
PCB.
