Spread presentation
The Spread sensor presentation is shown below.

and which identification number the sensor has on the PI54
system. In this example,
S3 means that it is a spread sensor, and
that it is sensor no.3.
(B) Unit of measure. [m] means meter, [ft] means feet, [fm]
means fathoms and [pb] means braccia.
(C) Readout of the actual distance between the two trawl doors.
(D) Increasing or decreasing distance speed of the trawl door
distance shown in units per minute. The two arrows (E) are used
to indicate if the distance is increasing or decreasing. If the
distance is constant and the speed is 0, the arrows are removed.
(E) Distance increasing/decreasing indicators. If the two arrows
point away from each other (as shown in the example), the
distance is increasing.
(F) Graphic alarm. The direction of the triangle indicates if the
trawl door distance should be increased or decreased with regard
to the selected alarm limits. If requested, this graphic alarm may
be accompanied with an audible alarms.
(G) Yellow pulse lamp blinks each time a signal is received
from the corresponding sensor.

interference from other nearby vessel(s) operating on the same
