TOKYO KEIKI PR-6000, YOKOGAWA PT-500A, PT-900

Steering functions are available when the ECDIS system is connected to the Autopilot.
To use a steering mode, set your Autopilot's system selection switch to the FU-1 or
FU-2 (PT-500A, PT-900), No.1 or No.2 (PR-6000) position.
PR-6000: No.1, No.2 position
PT-500A, PT-900: FU-1, FU-2 (Follow Up) position
Hand (manual) steering mode (Mode selector: HAND)
Set the Steering Mode Selector Switch to HAND. The ECDIS displays the rudder an-
gle and indicates the steering mode in the [Route Information] box.
Autopilot steering mode (Mode selector: AUTO)
The operator sets the required heading of the ship with the Course Setting knob. Turns
are controlled by the rudder limit or rate of turn and are started the operator.
Turn the Mode selection switch to the AUTO position, and the set course is shown in
the SET. COURSE display. The initial value of the set course is the ship's heading at
that time. To change the course, press the Course setting knob and release it when
the required course appears. Now, the course deviation (CO.DEV: COURSE DEVIA-
TION) is shown in the bar graph and AUTO is lit. AUTO goes off when the ship is fol-
lowing new course.
When the loading condition changes remarkably, yawing can large at the departure.
Then, do auto course; change by 20° of port and starboard two or three times, and
follow the state for approx. 15 minutes.
Turn controlled by the rudder angle: When a new course is set, turns are controlled
by the rudder angle. You can set the required rudder angle limit with the Rudder limit
knob.
Turn controlled by rate of turn: Press the AUTO unit <-SEL switch a number of
times to light the data selection indicator R.O.T. and show the rate of turn (unit deg/
min). Now, press the DATA CHANGE switch (located at the lower right) to show the
turn rate order. The displayed value can be changed with - or + while pressing the
DATA CHANGE switch. This value becomes the turn of rate order during automatic
course change. The setting, however, cannot be changed during automatic course
change.
Route steering mode (Mode selector: NAVI (PT-500A), RC (PR-6000))
GoSEA mode (open sea mode): The planned track is followed at moderate and "eco-
nomical accuracy" between waypoints and also during the turns (position-controlled
turn). When the ship nears a waypoint, the ECDIS alerts the operator both well before
the turn and just before the turn.
GoAW mode (all waters mode): The planned track is followed at the "maximum ac-
curacy" between waypoints and also during the turns (position-controlled turn). When
the ship nears a waypoint, the ECDIS alerts the operator both well before the turn and
just before the turn.
