Rudder Alignment Test - Dockside Wizard

[mlpayne9367@gmail.com]

My installation is an EV-200 Sail Autopilot pack.
EV-1 sensor core.
P70 control head.
ACU-200
Rotary Rudder Reference Transducer
Type-1 rotary drive

My question: In commissioning the autopilot, running the Dockside Wizard, I see the rudder reference transducer shows an initial reading that does not correspond to the physical wheel / rudder alignment to center; the transducer is reading almost 20 degrees to Port when the wheel / rudder is physically centered. See file attachment *pdf with pictures of the transducer's placement, P70 screens and description. Is there a way to initialize the transducer reading to center before going through the wizard's calibration? Look at the picture of the transducer's placement in relation to the rudder centered quadrant. Have I installed the transducer incorrectly?
