TP Reduced Radius
The Track mode is in the switched-on state, but the set radius for the next turn is too large to
enable the ship to reach the next leg by means of the manoeuvre that is planned at the TO-
waypoint. For this reason, the TRACKPILOT will reduce the radius to such an extent that the course
change can be performed.
A reduced radius can result in an increased ROT during the planned turn.
Remedy: Switch over to Course mode or Heading mode.
TP Rudder Error
The rudder engine is not obeying the instructions from the TRACKPILOT, or is not doing so with
sufficient accuracy.
Special feature: The message initially appears as an indication without an acoustic signal. If the
cause of the fault continues to exist for more than 10 seconds, the acoustic alarm signal appears
additionally and the priority is increased to Alarm (1). The alarm can be acknowledged, but is
repeated for as long as the cause of the fault continues to exist.
Remedy: Check the steering gear, the rudder pumps and the TRACKPILOT interface.
TP Rudder Feedback Differs
The signal of the main rudder feedback unit deviates by at least 5 degrees from the signal received
from the redundant rudder feedback unit.
Remedy: Switch over to manual steering. Check the rudder feedback units (wiring, signal, mechan-
ical function).
TP Rudder Limit
The set rudder limit value has been reached; with this rudder limit, the activated manoeuvre can
most probably not be performed without a deviation
- or -
The present rudder angle lies outside the rudder limit.
Remedy:
- Increase the rudder limit or
- wait until the rudder angle becomes less than the rudder limit or
- switch over to manual steering.
If this alarm is present for a longer time, it is necessary to switch over to manual
steering.
In Track mode on ships with DNV NAUT-AW approval, limitation by the set rudder
limit is ignored when a planned manoeuvre is being performed (i.e. during the
turn at the waypoint)
