After acknowledgement, the text line is faded out; simultaneously, the NEW TRACK
course appears in the
SET COURSE indication.
If -- after change--over to the operating mode of track control -- the ship is still outside
the pre--defined monitoring limits (TRACK MAX and COURSE MON), these parts of
the bar graph indication will be flashing.
For the
OFF CRS (off heading) indication, one flashing element corresponds to a set
heading trim deviation of 2

.
The flashing tendency indications diminish as a function of automatic track follow--up.
The track run--in phase is terminated as soon as the track deviation and the heading
deviation are within the preselected monitoring limits.
The OFF TRACK monitoring is now active.
The set course trim is indicated by the centre deflection of the OFF CRS bar graph
indication by 2

steps. The set course trim describes the course deviation within the
monitoring limits.
Dependent on the current drift and weather condition, heading fluctuations appear
within the indication which will be compensated via the track controller.
The set course trim may show values in the range of

30

.
The track deviation is indicated by drifting of the OFF TRK bar graph indication.
If a track deviation exceeds the monitoring range, OFF TRACK alarm is given (audi-
ble alarm and plain text information in the text line).
The possible causes are as follows (see Chapter 2.6):
-- a too strong drift that can no more be corrected by off course trim of 30

or when
(after change--over to operating mode TRACK) the ship is outside the track
monitoring limits.
-- if change--over to a new track section is initiated too late (see Chapter 2.2.8.1)
-- when there is a defect in the steering control circuit.
The rudder angle indicator indicates the rudder order (2

per step).
