Series 5000 V2 Sonar System Operations and Maintenance Manual P/N 11214512, Rev. 04
9. Perform a rub test on the port and starboard transducers to confirm that the
receivers are operating properly. Do this test by vigorously rubbing each
transducer, one at a time, while observing the Sonar Viewer window in
SonarPro for returns.
10. Exit SonarPro and turn off the SonarPro Workstation and the TPU.
3.8.2 Activating and Testing the System at Sea
To activate and test the system at sea:
1. Verify that the towfish has been properly set up and the system components
connected.
2. Turn on the navigation system and let it acquire its location.
3. Verify that the tow cable is connected to the towfish and to the TPU.
4. Turn on the SonarPro Workstation and wait for the Windows desktop to
appear.
5. Turn on the TPU.
After 10 seconds the POWER indicator should turn on and the SYS READY
indicator should flash. After approximately 1 minute the SYS READY and
AWAKE indicators should turn on, the DOWNLINK and TRIGGER
indicators should flash, and the TF POWER should be on.
6. Start SonarPro and observe that the towfish is transmitting by viewing the
output pulse in the Sonar Viewer window. Also check that sensor data are
being displayed in the Information window.
7. If a GPS is connected, check that navigation data are being displayed in the
Information window.
8. Deploy the towfish.
CAUTION Serious damage to the towfish electronics may occur if the
towfish is operated on deck for periods longer than fifteen minutes.
Between periods of operation, let the sonar cool for fifteen minutes. In high
temperature climates, protect the towfish from direct exposure to the sun prior to and
during operation.
CAUTION When the towfish is close to the sea floor, the bottom tracking
(altitude) performance is less accurate. Exercise extreme caution when
operating the towfish at altitudes of less than 4 meters (13 feet).
