Refer to the drive unit table on page 58 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 AP20 system will

automatically detect whether the drive unit is a reversible motor

or solenoid operated.

To change the voltage selection, rotate the course knob.

Note ! The drive unit voltage setting does not apply when operating

solenoids on a continuous running pump/steering gear. Hence,

the output voltage to the solenoids will be the same as the input

voltage.

Proceed to next menu item by pressing STBD [>] button.

Rudder Feedback Calibration

Make sure the RF300 is installed and aligned as pr. instruction in

section 4.6 (or eventually section 4.27 for LF3000). This

function enables you to compensate for any non-linearity in the

transmission between the rudder and the rudder feedback.
