2.2.5 Trackpilot Alarms
The following list of alarms, warnings and indications contains all alarms for all operating modes
(Heading, Course, Track) of the TRACKPILOT. In systems with Heading mode only, alarms of the Course
and Track mode are not initiated.
TP Astern Speed
The TRACKPILOT is in the activated state and the selected speed sensor is producing negative
(astern) speed data (which the TRACKPILOT cannot process).
WARNING: While this alarm is present, the steering gear is not being driven by the TRACKPILOT.
When the TP Astern Speed alarm appears, it is necessary to immediately change to some other
speed sensor or to switch over to manual steering.
Special feature: The alarm cannot be acknowledged. It is repeated and disappears when its cause
has been eliminated.
TP Backup Navigator Alarm
The TRACKPILOT Alarm signal was generated.
Causes for generating the TRACKPILOT Alarm signal: See 2.2.6 on page V-32.
Special feature: As long as the TP Backup Navigator Alarm alarm has not been acknowledged,
the TRACKPILOT Alarm signal remains active.
TP Change Position Sensor
While the system is in Track mode,
- the selected position sensor has not transferred any valid data for a longer period, or
- a switch-over has taken place to a position sensor which is not transmitting valid data, or
- a switch-over has taken place to a position sensor which is not permitted as a continuous
sensor for Track mode.
- or -
While a position sensor is being used which is not permitted as a continuous sensor for Track mode,
a switch-over to Track mode has taken place.
Special features: Until the cause of the alarm has been eliminated, the alarm is repeated after 1
minute. The TP Track Mode Fault alarm appears after 10 minutes if the cause of the alarm has
not yet been eliminated
Remedy: Select a position sensor with valid data, or a permitted position sensor.
TP Course Limit
The set course limit has been exceeded.
Remedy:
- Increase the course limit or
- wait until the TRACKPILOT has eliminated the course deviation, or
- switch over to manual steering.
