Detailed description
Information loop 1 (INFO I)
This loop is entered by pressing the INFO button. The parameter are
as follows (First display readout depends on what has been selected
by "Rate of turn (RATEoT) steering/Radius steering", see page 2-10):
Turnrate
The autopilot has a selectable automatic "Rate Of Turn" or "Radius
Turn" function. The Rate Of Turn function is used to maintain a
predetermined turn rate (in degrees per minute). The activation of
the turn rate function is determined by the following condition:
The turn limit value is limited to maximum 20 degrees and minimum
3 degrees.
Example 1:
A turn rate of 50°/min. has been set. A 90° turn is made. According
to the turn rate formula above, the turn rate control is activated when
the course has changed by 50°/min./4,9 = 10,2 degrees.
Example 2:
Turnrate of 120°/min. has been set and a 90° course change is made.
According to the formula, the turn rate control should start at 120/4,9
= 24,5°, but this is limited to 20°.
Range:
The TURNRATE function is only activated when using the course change

knob. NOT the Port and STBD buttons.
Radius
The turn control function may also be selected for Radius Turn. For
this function speed information is required from GPS via the serial
Nav input. The autopilot will sense the speed regardless of NAV
mode steering or normal AUTO steering is selected.
The relationship between set turn radius and corresponding turn rate
and vice versa is calculated internally. Hence the same limitations of
maximum and minimum radius steering applies.
