No communication with the device
(In this case the Node number of the device is 2). Check
the power and communications links to the sonar head for
continuity and for correct polarity, voltage and ensure that
the power supply can provide sufficient current to power
all devices. If internal damage is suspected, contact
Tritech International Ltd for service and repair options.
The head has lost its bearing during the scan.
This may be a result of a sudden knock or collision that
may have damaged the transducer and/or stepper motor
shaft. The transducer will correct its bearing at the end of
the scan but if the error message is repeated then there
has been damage to the transducer or stepper motor.
Incorrect settings or malfunction.
Listen to sonar head in air. If it "clicks" audibly then
the transmitter circuit is OK. Check that the sonar was
not operated in clear water where there were no sonar
targets. Check the gain control is responding and not set
at a minimum.
Sonar at incorrect height above seabed.
SeaKing sonars have a vertical beam width of 20 -
40° about a centre line (plus and minus 10 - 20°) so
ensure that the head is positioned sufficiently close to the
seabed.
