30. Steering With TOKYO KEIKI Autopilot PR-6000
30-16
Alarm "2518 Disabled: Not accepted" informs you that the 30-second timeout period has passed after you pressed
the NAV and Enable switch buttons on the TOKYO KEIKI control panel. After you select "GotoOS" or "GotoAW"
at the ECDIS, you have 30 seconds to press the NAV and Enable switch buttons on the TOKYO KEIKI control
panel, otherwise alarm 2518 is given. Another reason can be that your ship has moved into a turning part of a
monitored route before you pressed the NAV and Enable switch buttons on the TOKYO KEIKI control panel.
Alarm "2519 Trackpilot: XTE comp.limit" warns you if TCS is unable to get your ship to approach the track. An
alarm is triggered if your ship is outside the channel limit and if the cross track error is still increasing.
Alarm "2788 System Frozen" appears as an early warning indication that the system may freeze. In this case, restart
the ECDIS EC1000C processor.
30.4.8 Collision avoidance maneuver during automatic route
steering
Often the route steering is interrupted by a collision avoidance maneuver, but there are also several other reasons to
interrupt the route steering.
There are several possibilities to set the collision avoidance or any other maneuver:
• Use the HAND steering control. (Change mode from "RC" to "HAND").
• Use the local Autopilot Heading control. (Change mode from "RC" to "AUTO").
• Use the Non Follow Up steering lever to control the rudder pumps directly. (Change mode from "RC" to
"NFU").
Now the route steering is disabled until the "RC" mode in Autopilot panel is selected again. Then, press the NAV
and Enable switch buttons together. To go back to route steering, the ship heading must be pointed toward the next
waypoint and the ship must be located inside the channel limits, otherwise an alarm is given.
