Drive unit voltage selection
This menu option requires the installer to set the drive unit
voltage to the correct level. The selections are 12V, 24V or 32V
(32V only with J300X/J300X-40) and should be set to the voltage
specified for your drive unit.
Note ! Selection of improper voltage level for your drive unit may damage
both the drive unit and junction unit even if the protection circuits in
the junction unit are activated.
Refer to the drive unit table on page 60 for information. It is not
possible to select a higher voltage than the input voltage. The
CLUTCH/BYPASS voltage is automatically set to the same as the
drive unit voltage. In Rudder Test, the autopilot system will
automatically detect whether the drive unit is a reversible motor
or solenoid operated.

Rudder Feedback Calibration
Make sure the RF300 is installed and aligned as pr. instruction
in section 4.6 (or eventually section 4.29 for LF3000). This
function enables you to compensate for any non-linearity in the
transmission between the rudder and the rudder feedback.
