  • Page 20: Key Feature Setting

    974-24007001/3.0 FS 70 Operators Manual Page 2.4 Theory of Operation After the TVG correction, the absolute levels of the received signals will be determined by the acoustic response of the reflecting target. The sonar processor system repeatedly measures the TVG corrected target levels by digitizing a sequence of samples after each sound pulse transmission.

    FS 70 Operators Manual 974-24007001/3.0 Theory of Operation Page 2.5 2.1.4.3 RX Gain Response and Type The setting of the “RX Gain Response” determines the response of the filter algorithm as selected by the “RX Gain Type”.

    974-24007001/3.0 FS 70 Operators Manual Page 2.6 Theory of Operation 2.1.4.7 Peak Detection The Peak Detection feature is described as follows. The older sonar heads were not capable of changing the acoustic pulse length. They were generally operated at a pulse length of 100 Microseconds. This meant that at a range greater than 50 meters, there would have been a good chance of not detecting small targets.

    In addition to the above equipment, but not supplied by Simrad, the system requires a winch with slip-rings, and a trawl cable for connection of the FS trawl unit to the wheelhouse electronics.

  • Page 72: Handling & Maintenance

    The cables allowable closed loop resistance is 100 ohms. HANDLING & MAINTENANCE The most common causes of failures to the Simrad FS Trawl Monitoring system are: 1. Trawl cable and/or winch slip-ring problems, 2. Sonar head and sensor module connector and interconnect cable failures.

    FS 70 Operators Manual 974-24007001/3.0 Troubleshooting and Maintenance Page 5.5 5.3.2 Trawl Unit The Trawl Unit is subjected to the harshest conditions and therefore proper handling and maintenance is crucial to ensure trouble free operation. 5.3.2.1 Handling Tips • Though the trawl unit electronics are ruggedized for the fishing environment mishandling or repeated impacts may result in damage to, or failure of, the electronic components.

  • Page 74: Connector Maintenance

    1. Wipe connectors clean of old grease and dirt with a lint free cloth. 2. Inspect the connector’s metal contacts and sealing surfaces for corrosion, wear or damage. If problems are found, return the unit to a qualified Simrad service facility for replacement of the connector! 3.

  • Page 75: Corrosion

    The winch slip-rings and trawl cable are the umbilical cord between the processor unit and trawl unit electronics, and are critical to the proper operation of the Simrad FS Trawl Monitoring system. Damaged, worn or poorly maintained cable or slip- rings will degrade the performance of the system and may cause or lead to a complete system failure.

  • Page 76: Monitoring System Performance

    Part 7 “Drawings”. MONITORING SYSTEM PERFORMANCE There are a number of tools available with the Simrad FS Trawl Monitoring system that allow its performance to be checked. When these tools are utilized as part of the regular maintenance they provide information about the state of the system and allow it to be monitored.

    FS 70 Operators Manual 974-24007001/3.0 Troubleshooting and Maintenance Page 5.9 For the FS 70 system, the trawl cable and test cable are both connected to the 3-pin connector (“2-wire”) on the rear panel of the PWR/TTM unit. To install the test cable, disconnect the trawl cable and attach the test cable.

If this value is higher than a previous value obtained on the test cable then the problem is likely with the trawl unit electronics. If the current readings are the same on test the cable as previously obtained, then the trawl cable and winch slip-rings should be checked.

    TROUBLESHOOTING In the event the Simrad FS Trawl Monitoring system does not operate correctly care must be taken to properly diagnose the cause of the failure. Quite often the failure is thought to be with the FS electronics when the actual cause is due to the winch slip- rings, the interconnect cable or the trawl cable.

  • Page 80: Diagnosing Problem

    Power up the system and repeat step 1 and 2. Note! If a Simrad FS unit is diagnosed as being faulty, then the unit(s) should be returned to an authorized Simrad service center. ALL system performance results and a complete description of the problem should be supplied with the defective unit to assist in its repair.
