Special features:
- Acknowledgement causes switch-over to Heading mode and acceptance of the displayed gyro
heading value. The currently existing heading value is taken over as the set value.
- In addition, acknowledgement can force the TRACKPILOT to generate larger rudder angles.
- If the cause of the alarm has not been removed (i.e. the gyro heading is still invalid), the alarm
is repeated even after acknowledgement.
If the alarm is not acknowledged within 30 seconds, the TRACKPILOT Alarm signal is
generated for the purposes of triggering an external alarm. See 2.2.6 on page V-32
Remedy (after the switch-over to manual steering has taken place):
Check the compass system; if possible at the compass system, select another heading source. Check
the displayed heading before use.
TP High Rudder Limit (high ROT)
1)
The TRACKPILOT internal monitoring function of the rudder limit, set by the operator, has deter-
mined that with this maximum rudder deflection at the currently sailed speed a high rate of turn
above the limit would be produced.
Special feature: This warning cannot be acknowledged, it will disappear if the cause for this
warning has been eliminated.
Remedy: Decrease the rudder limit or reduce the speed.
TP Low Rudder Limit
2)
The rudder limit is set so low that - during Track mode - the next course-change possibly cannot
be performed with the planned radius.
Remedy: Increase the rudder limit, increase the radius, or leave the Track mode.
TP Low Speed
The speed reported by the selected speed sensor is so low that the TRACKPILOT might not be able
to steer the ship correctly.
Special feature: Acknowledgement causes a switch-over to Heading mode.
Remedy: Switch over to manual steering.
TP Low Track Limit
2)
The track limit setting is lower than the expected average position-error of the selected position
sensor.
Remedy: Increase the track limit or select a more accurate position sensor.
While this alarm is present, the steering gear is not being driven by the TRACK-
PILOT.When this alarm appears, a switch-over to manual steering must be
performed immediately.
1)
This alarm can only appear if activated on service level; for this function a maximum allowed ROT value must be
set in the system configuration.
2)
This alarm can only appear if activated on service level; required for ships with DNV NAUT-AW approval.
