OPERATION
NautoPilot 5000 Series
AUTOPILOT
Radius
NautoPilot 5100, NP 5300 and NP 5400:
The ECDIS transmits Course Over Ground (COG), Rate of Turn (RoT) and Cross Track
Error (XTE) to the Autopilot. The ECDIS transmits no waypoints and the Autopilot re-
quests no data for a track.
NautoPilot 5500 only:
Before Track Control is started, WPTs are transmitted to the Autopilot (up to 4 way-
points). This process is called initialisation.
During this initialisation all necessary data for Track Control are transmitted to the
Autopilot.
Further WPTs (and data) are transmitted during Track Control from the ECDIS to the
Autopilot on request of the Autopilot.
After initialisation, the Autopilot is switched into "Track Control" mode and the ship ap-
proaches the first track section.
Within a time between 3 to 5 min before a track change manoeuvre starts, the
operator is notified of the forthcoming track change manoeuvre by means of a message
from the Autopilot. The time can be selected at the ECDIS. This message must be
acknowledged by the operator. 30 seconds before the track change manoeuvre starts,
the operator is requested by the Autopilot to acknowledge the forthcoming track change.
The track change is realized even if those messages are not acknowledged.
At the end of the route, the operator is notified by an alarm that the ship is at track end,
and he is requested to change over to Heading Control mode or manual mode.
The activation of Track Control is only possible under the following conditions:
1. The Autopilot is in the operating mode of Heading Control.
2. Track Control is activated from RAYTHEON Anschütz ECDIS.
In general:
Controller parameter like rudder, yawing, economy etc. can be adjusted at the Autopilot.
Please note:
Parameters RoT and radius (RAD) limits should be adjusted for a non RAYTHEON
Anschütz ECDIS accordingly.
