Trawl info setup
These settings are used to set up the PI54 parameters related to
the trawl presentations on the Graphic display. When enabled,
marker lines providing trawl depth information will be
superimposed on the display.
The marker lines are enabled in the Marker line setup.
To access the parameters, press the ADJ (Adjust) button when
you have a Graphic display in the active window. Then, press
the GAIN+ button until the parameters appear. You can also
press the MENU button to access the Echo quick menu,and
then select Graphic setup (8).
Headrope sensor: This setting defines which sensor that is
placed on the headrope.
Footrope sensor: This setting defines which sensor that is
placed on the footrope.
Trawl opening mode: T his parameter decides how the trawl
opening shall be recreated on the Graphic Display. If you have
sufficient sensors on the trawl you must select Auto, and the the
PI54 will automatically calculate the trawl opening and draw it
accordingly. If you only have one sensor on the trawl opening
(Depth or Height sensor on the headrope), the Manual setting
will add an artificial line on the Graphic Display. The distance
from the headrope to the footrope must then be defined
manually using the Manual trawl marker parameter (below).
Manual trawl marker: Set the manual trawl opening height f o r
use with the Trawl opening mode parameter (above).
Clump sensor: This setting defines which sensor that is placed
on the clump.
Door sensor: This setting defines which sensor that is placed on
the door.
