The Link LED Illuminates continuously as the 3400 Topside establishes a reliable communications link with the sub-bottom sonar. It flashes when a reliable communications link with sonar is established. The blue LED lights up during startup to show system initialization, then shuts off. Once the system begins pinging, the LED blinks continuously. A Tri-Color Data indicator LED. The LED is green when the data is good. If the signal degrades, it will turn to yellow and then red, showing data loss. 3400 Sub-Bottom Sonar System 0021825_REV_A 2-7 2.2 Performing Sub Bottom Pre-Deployment Checks EdgeTech suggests checking for diagnostic warnings and then performing pre-deployment checks. Both checks should be performed before the tow vehicle is deployed and after the system is activated. Discover Diagnostic Warnings: Discover provides default popup diagnostic warnings if certain failures occur when the system, sonar, or subsystems are turned on or off. These will appear in Diagnostic Information popup windows. Figure 2-2: Example Diagnostic Warning- No Towfish Connected The Discover Radio Indicator Tabs in the Lower Control Panel on the lower right side of the Discover UI displays the current status and warnings of the 3400 system. Detailed descriptions of status messages are found in the Radio Indicator section of the 3400 SOFTWARE MANUAL. Figure 2-3 Radio Indicator Tab Pre-Deployment checks involve: 1. Listening for the transmitted pulses from the transducers on the tow vehicle 2. Tapping gently with a screwdriver handle or hand near the PVDF panel while observing the Sub- Bottom Displays in the Discover Application Window, ensuring it plays back and navigation is present. The Discover 3400 Application Windows is shown in the figure below, and the tap test results are displayed in FIGURE 4-9. NOTE: See the DISCOVER 3400 SOFTWARE MANUAL for detailed software information. 2-8 Figure 2-4: Discover 3400 Application Window To perform the pre-deployment checks: 1.

Test that the vehicle's compass works correctly by moving the towfish and checking that the pitch and roll are reported correctly in the Main Status Line Display in Discover. · Verify that the starboard roll is correct by rotating the fish's tow arm towards its starboard direction around 20 degrees. The Roll value should be positive in this direction and reach a max of +180 degrees. · Verify that the port roll is correct by rotating the fish's tow arm towards its port direction around 20 degrees. The Roll value should be negative in this direction and reach a max of - 180 degrees. · Verify that the pitch is working correctly by lifting the nose of the fish. The pitch value should read positive and reach a max of +90 degrees. · Verify that the pitch is working correctly by lifting the vehicle's tail. The pitch value should read negative and reach a max of -90 degrees. 3400 Sub-Bottom Sonar System 0021825_REV_A 3-11 3.0 DEPLOYMENT Points to be considered for the deployment of 3400 Vehicles: · Location of the propeller of the vessel. It may be better to deploy from the side of the boat in shallow water. · Expected turning direction during deployment. When deploying a towed variant from the side of the boat turns should be made so the vehicle swings away from the propeller. · Bending the cable with a radius less than 5 inches may cause damage to the cable. Do not bend the tow cable sharply. Deployment: 1. Depending on the situation and conditions, the vessel should be underway at a slow speed (0-2 knots) or stopped in neutral. 8. Slowly and carefully lower the towfish to a safe depth-just below the propeller wash (2-3 meters, depending on water depth). Do not strike the towfish against the side of the vessel. 9. Normalize the gain in Discover by clicking the N icon button and observe the data. Adjust TVG manually as needed to have a uniform display color. Figure 3-1: Shortcut Toolbar Normalize Gain and Normalize TVD Buttons 10. Observe and track the first bottom return. 11. Once you are sure that you have detected the seafloor, carefully lower the towfish to the desired depth (about 5m from the seafloor is ideal). CAUTION! Do not strike the seafloor. This may foul or damage the vehicle. 12. Check that Discover is still tracking the bottom, and adjust the tracking parameters. 13. Increase the boat speed to the desired survey speed (normally between 3-5 knots) and re- adjust the amount of cable out so that the altitude of the towfish is correct. 14. In Discover's Disk Tab, name the file in the file record textbox, and choose the desired path for the file. 3-12 Record Button Disk Tab Record File: File Name Entered.
