FS 20/25 Operators Manual Theory of Operation 2. 2.1 901-10037001/1.1 Page 2.3 THEORY OF OPERATION INTRODUCTION This section explains the theory of operation of the Vertical and Horizontal Scanning Trawl Monitoring Sonar System. 2.1.1 Basic Principles • Sound waves travel very efficiently through water. • A sound pulse can be projected through water in a controlled direction with the sonar transducer.
901-10037001/1.1 Page 2.4 FS 20/25 Operators Manual 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. Each sample is then plotted on the video display at the appropriate position according to its range and bearing.
FS 20/25 Operators Manual Theory of Operation 901-10037001/1.1 Page 2.5 Note that scattered fish can be perceived as reverberation. The RCG filter must be used with care if scattered schools are to be detected. 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”. For the AGC, this setting determines the speed by which the gain is adjusted.
901-10037001/1.1 Page 2.6 FS 20/25 Operators Manual Theory of Operation 2.1.4.7 Peak Detection The Peak Detection feature can only be 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 range greater than 50 meters, there would have a good chance of not detecting small targets.

FS 20/25 Operators Manual Maintenance and Troubleshooting 901-10037001/1.1 Page 5.3 5. TROUBLESHOOTING AND MAINTENANCE 5.1 INTRODUCTION This document is intended to provide a minimum level of instructions for the proper handling, maintenance and troubleshooting of the FS Trawl Monitoring System. The information is applicable to both the FS 20 and FS 20/25 systems. 5.2 SYSTEM OVERVIEW The Simrad FS Trawl Monitoring System (both FS 20 and FS20/25 consists of wheelhouse electronics and a trawl unit.
901-10037001/1.1 Page 5.4 5.2.2 FS 20/25 Operators Manual Maintenance and Troubleshooting Trawl Cable Requirements For whatever cable type and length used, the following specifications must be met for operation with the Simrad FS Trawl Monitoring system: Cable Closed Loop Resistance: Signal Attenuation Through Cable: <100Ω <40 dB (1/100 signal amplitude) @ 55 kHz <20 dB (1/10 signal amplitude) @ 12 kHz The cable closed loop resistance determines the maximum voltage drop along the trawl cable.
FS 20/25 Operators Manual Maintenance and Troubleshooting 5.3.2 901-10037001/1.1 Page 5.5 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.
901-10037001/1.1 Page 5.6 FS 20/25 Operators Manual Maintenance and Troubleshooting • End of Fishing Season The trawl unit package should be opened and the components cleaned with fresh water. The sonar head and sensor module should be inspected for corrosion or damage. Service all connectors and cover them with plastic. Store units in a dry, clean area.
FS 20/25 Operators Manual Maintenance and Troubleshooting 901-10037001/1.1 Page 5.7 5.3.2.4 Excessive Impacts Though the FS Trawl Unit is designed for the harsh fishing environment, excessive impacts to the trawl unit or the individual components may damage them. With the older fiberglass trawl housing, excessive impacts to the trawl unit usually resulted in physical damage to this housing.
901-10037001/1.1 Page 5.8 5.3.3 FS 20/25 Operators Manual Maintenance and Troubleshooting Catch Sensors The catch sensors are relatively maintenance free except to charge the batteries. Refer to your Simrad FA701 Catch sensor operator and installation manual for the information on both the charging of the catch sensors and the proper mounting of these sensors on the trawl.
FS 20/25 Operators Manual Maintenance and Troubleshooting 901-10037001/1.1 Page 5.9 For additional information on connecting to slip rings and examples of splicing trawl cable, refer to Part 7 “Attachments”. 5.4 MONITORING SYSTEM PERFORMANCE There are a number of tools available with the Simrad FS Trawl Monitoring system that allow its performance to be checked.
901-10037001/1.1 Page 5.10 FS 20/25 Operators Manual Maintenance and Troubleshooting For an FS900 deployment package, configured with an FS3300 head, be advised that the FS3300 head requires the most attention of the vertical heads, because it is the easiest to damage. The FS3300 head, when connected directly to the TTM/PWR unit with a test cable, should be run with the switch in “TEST”.
FS 20/25 Operators Manual Maintenance and Troubleshooting 901-10037001/1.1 Page 5.11 Realize that each 3rd wire cable is unique. The important thing to know is that if readings start to vary from your initial recorded values, and you start having problems with your system, this may be your first indication of a problem with the cable, pigtail, slip rings, etc. Any changes in the recorded meter values during normal operation may indicate a potential problem, even if the unit continues to operate properly.
901-10037001/1.1 Page 5.12 5.4.3 FS 20/25 Operators Manual Maintenance and Troubleshooting Trawl Cable Gain Signals passing through a length of cable are attenuated by an amount dependent on the type and length of cable used. The FS Trawl Monitoring system will apply gain to the signals to compensate for the cable losses. With both the FS20 and FS20/25 systems, the cable gain compensation has been automated.

901-10037001/1.1 Page 5.14 FS 20/25 Operators Manual Maintenance and Troubleshooting To observe if the system has experienced errors over a given period of time, you can go to “View”, highlight “Message Log” and “Click” beside “Visible”. The following example of the “System Message Log” has been enlarged to show details such as description, severity and full date/time information. This example shows that an FS20/25 System ran up to the fully operating condition, error free.
FS 20/25 Operators Manual Maintenance and Troubleshooting 5.5 901-10037001/1.1 Page 5.15 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, or the trawl cable. The following sections provide helpful advice on troubleshooting the FS system. 5.5.
901-10037001/1.1 Page 5.16 5.5.2 FS 20/25 Operators Manual Maintenance and Troubleshooting Diagnosing Problems As previously mentioned, the PC based FS Trawl Systems are more complex than prior systems to pinpoint a specific fault. The primary emphasis must be placed on determining initially if the problem can be traced to something other than the specific FS equipment itself.
FS 20/25 Operators Manual Maintenance and Troubleshooting 5.5.3 901-10037001/1.1 Page 5.17 Common Fault Recognition Charts This is a more complicated system than prior FS3300, MKI and MKII Processor based systems. In simple terms, the issues that existed before with the units in the deployment package (whatever configuration of heads and sensor modules) and the rd full 3 wire (including the slip rings) are the same.
1-10037001/1.1 Page 5.18 FS 20/25 Operators Manual Maintenance and Troubleshooting 5.5.3.1 PC to PWR/TTM Unit (Digital) The first stage in bringing the system on line is to have the PC establish a communication link with the digital portion of the LF Sub-assemblies. As far as the PC is concerned, it is talking to, and will eventually be running “digital head(s)”. This area of the run up sequence occurs during the “Connect Heads”, and then “Detect Heads” phase (Refer to Section 4.4.4).
FS 20/25 Operators Manual Maintenance and Troubleshooting 901-10037001/1.1 Page 5.19 The system configuration, if installed correctly, will have the cable that plugs into PC COM Port 1 establish communication with the LF1 Sub-assembly (Vertical Head). The cable that plugs into PC COM Port 2 will establish communication with the LF2 Sub-assembly (FS925). Using the above symptoms as an example, if you did a full system run up, eventually the Vertical head would start to work but the FS925 would not.

901-10037001/1.1 Page 5.22 FS 20/25 Operators Manual Maintenance and Troubleshooting 5.5.3.3 PWR/TTM Unit The PWR/TTM Unit performs the following functions: 1. Generation of DC Voltages to run the LF Sub-assembly electronics. 2. Generation of High DC Voltage supplied to the Deployment Package (see section 5.4.1). 3. Communication Interface (discussed in previous sections). An FS20/25 System will be used as the example for an internal power supply failure to the LF Sub-assemblies.

FS 20/25 Operators Manual Maintenance and Troubleshooting 901-10037001/1.1 Page 5.25 5.5.3.5 Full 3rd Wire Assembly (Including Slip Rings and Wheelhouse Cable) The absolutely weakest link in the entire FS Trawl Fishing System is the 3rd Wire Pigtail Connection. If the female inserts have been contaminated with salt water and start to corrode, they will cause the 2-pin connector pins of the attached head to corrode and/or “burn”.
901-10037001/1.1 Page 5.26 FS 20/25 Operators Manual Maintenance and Troubleshooting If the impedance between the cable’s two conductors is too low, then possible problems are bad splices, water in cable, moisture in slip rings (if connected during test), or damaged cable. If the impedance between the cable’s conductors and the vessel’s hull is too low, then possible causes are damaged outer jacket on cable, bad splice, or bad slip rings (if connected during test).
