Bottom Contact presentation
The Bottom Contact sensor presentation is shown below.
(A) The character and the number identifies the type of sensor,
and which identification number the sensor has on the PI44
system. In this example,
B4 means that it is a bottom contact
sensor, and that it is sensor no.4.
(B) Status field. The three arrows display “bottom contact”,
graphically represented by the black or red downward pointing
arrows in contact with the horizontal black line. Upon loss of
bottom contact, the arrows will rise from the black line (seabed)
and change colour from black to red. At the same time an
audible warning is sounded, and the timer starts. Bottom sensor
measurement range may be adjusted as necessary.
(C) Timer, records how many minutes that have elapsed since
the sensor lost bottom contact. If the bottom contact is regained,
the timer stops. It is then restarted once the status changes again.
The timer must be manually restarted in the
Numeric setup .
(D) Yellow pulse lamp blinks each time a signal is received
from the corresponding sensor.
(E) Interference warning, activated when the PI44 detects
interference from other nearby vessel(s) operating on the same
channel or with similar hydroacoustic equipment. Contact your
Simrad dealer to select a different frequency should this
problem persist.
