Heading Monitor) at the initial display. It allows settings from 5
to
30
in increments of 1
.
The difference between Gyro heading and magnetic heading exceeds the preset
threshold, an alert is generated.
During a heading change maneuver this function is automatically paused, due to
the inert behavior of the Magnetic compass.
For switching on or off the Heading Monitor refer to Installation Manual, chapter
on Heading Monitor.
1.3.6
OFF Heading
This function compares the actual heading value against the set heading value.
There is an alarm if the limit between set heading and actual heading exceeds a pre-
adjusted value (Page

Limit
→
OFF Heading). See also section 2.3.6.4.
The possible range for pre- adjusted OFF Heading value 5
to 30
(in increments of
1
). The alarm is suppressed for a calculated time after a heading change
maneuver (calculation is based on RAD or RoT
→
time window).
The time window is calculated from the difference in the desired heading and
the preselected turning rate.
If, during the heading change maneuver, the ship reaches the heading alarm
threshold within the time window, no alarm is triggered.
