TP Rudder Relay Failure
An error has occurred in the relay controlled rudder control system.
Remedy: Switch over to manual steering. Check the rudder control system (wiring, steering relays
etc.).
TP Rudder Synch. Error
The rudder angles of the two rudders controlled by the TRACKPILOT differ by at least 5 degrees.
Remedy: Switch over to manual steering. Check the rudder control system and the synchronism of
the rudders.
TP Short Radius
So that the planned manoeuvre can be performed with the actually set radius, the expected rudder
angle would have to be larger than the maximum value that the TRACKPILOT can apply.
Remedy: Increase the radius or switch over to manual steering.
TP Speed Jump
The speed transferred from the selected speed sensor has jumped by more than 5 knots.
Special feature: Up until acknowledgement takes place, the TRACKPILOT uses the longitudinal and
transverse speeds that were valid before the alarm. After acknowledgement, the TRACKPILOT uses
the new longitudinal and transverse speeds.
Remedy: Check the new speed value. If it is correct, acknowledge the alarm; otherwise, select
some other speed sensor before acknowledgement.
TP Speed Sensor Fault
The TRACKPILOT is in an active steering mode and the selected speed sensor is reporting incorrect
data or has failed; steering with the drift angle taken into account is not possible.
- or -
The TRACKPILOT had been operated in Track mode and the selected sensor is reporting incorrect
data or has failed or Manual Speed has been selected as the speed sensor. When the alarm appears,
the system is automatically switched over to the Heading mode.
Special feature: For as long as no valid speed data are being received, the alarm is repeated.
Remedy: Select some other speed sensor or change to manual steering.
TP Track Data Error
The TRACKPILOT reports transfer errors or data errors of the activated System Route or the route
was deactivated by the operator.
Remedy: Switch to Course mode or Heading mode or manual steering. Check the waypoint data,
of the activated route. Deactivate and activate the route again.
If this alarm appears, the data of the pre-planned track are unreliable. The track
data must not be used for navigation.
