Rudder test Done

Clutch NOT installed

Rudder limit 10°

Rudder deadband 0.2°

Thruster ----

Necessary deadband to avoid the rudder from hunting is

calculated and set automatically during the rudder test. Therefore

this parameter should normally not be adjusted. If the auto-

setting does not perform properly (rudder commands due to

vibration of the rudder when under way), it can be adjusted

manually. A narrow deadband may cause the rudder to hunt and

a wide deadband will create inaccurate steering.

Adjust the Rudder deadband by rotating the course knob. Find

the lowest possible value that will prevent the rudder from

hunting. It is recommended to check rudder stability and

accuracy in FU-mode.

Range: Auto, 0.1° to 4.0° in 0.1° increments.

Default: Auto.

Proceed to the next menu item by pressing the (STBD)

button.

Interface Set-up

The AP50 system provides a flexible approach to the input of

data from heading sensors and other external equipment.

Identification of the type of equipment connected to the AP50

system is performed in the Interface Menu.

To be able to display all the information on the instrument

screens (see section “Instrument Screens and Menu” in the

Operator Manual), refer to the table in section 6.18 on page 110
