1. SYSTEM FAMILIARIZATION
1.1 OVERVIEW
The SIMRAD FS 70 Series is a third wire trawl monitoring system for pelagic and bottom fishing trawlers. The system provides real time images from the trawl sonar head and data from the sensors to the bridge, thus maximizing the quality of the catch and reducing sea time.
The FS 70 vertical trawl sonar allows the operator to see the complete net opening and operation by displaying individual fish targets in the vertical plane, the fish school location, bottom/net location and net geometry. In addition to the vertical monitoring, the FS 70 also allows the operator to measure the spread of the trawl door, view and skim banks to avoid reefs and locate boulders on the ocean floor that may damage the trawl net.
The 200kHz Echo Sounder capability ensures maximum control of the foot rope during the tow. The active motion sensor for pitch and roll comes as a standard feature.
The addition of the trawl system’s sensor module will allow the operator to monitor trawl depth, water temperature and receive information from up to 6 catch receivers indicating when the cod end fills up with fish.
The FS Trawl Sonar Series is a modular system. It is operated with ease through direct access Mouse and Keyboard operated menus. The major benefit of the third wire trawl sonar system is that it prevents the loss of communication with the trawl as the vessel is changing course.
1.1.1 Equipment Configuration
A complete Trawl Monitoring System consists of:
• Simrad LCD or VGA display monitor. (optional)
• FS 70 Processing Server Industrial Unit.

1.1.3 Display Monitor
The display monitor for the FS 70 can be a VGA ruggedized LCD monitor but any commercially available VGA monitor may be used. This is in order to have the full benefit of high resolution provided by the video Multi-Display adapter available with the FS Processors.
1.1.4 Processor Unit
The FS 70 19” Rack mounted Industrial Processing unit is the control unit for the system. The installed FS 70 system software provides a mechanism for the sonar head detection, setup and operation. It is operated through the Main Control panel to enable the Sonar selection, tilt, range, gain, cursor, and by moving the mouse pointer over the toolbar will allow the operator to perform certain operations with a simple Right or Left mouse click.
Port Coquitlam, BC - Canada
FS 70 Operators Manual 974-24007001/3.0 System Familiarization Page 1.5
The sector heading and width are also controlled by a single mouse click used to set the center of the area to be scanned and the width of the sector scan (up to 360°) in the polar mode.
The rear panel of the Processing unit contains the connectors for AC power, Dual Monitor port, one Serial port and several USB ports, Keyboard, Mouse, Printer, and Network port. The Network port can be used to connect the remote workstation. Note: A security key (or “dongle”) must be attached to a USB port to enable full operation of the system.
1.1.5 Power /TTM Interface Module
The FS 19” Rack mounted Power/TTM interface Module unit provides the high voltage required by the trawl sonar. The DC output voltage is combined with the telemetry signals and supplied to the trawl sonar.
The power voltage supplied to the sonar head and current are monitored by voltage and current meters. A selector switch located below the voltage meter can be used to select the output voltage of the power supply required for the appropriate system configuration. Also, a separate on/off switch is located in the front panel. Note: The main on/off switch and fuse are located on the rear panel of the TTM Module.
The Power/TTM Interface provides translation between the Processing Unit Serial or USB port and the sonar telemetry communication protocol.
A Test Cable connector and selection switch between the trawl cable and Test cable are provided in the front panel, eliminating having to disconnect the 3
rd
wire cable
from the rear of the TTM.
1.1.6 Deployment Housing Unit
The trawl deployment housing unit is made from polyurethane and designed for the harshest of environments yet it is easy to handle. The FS 70 trawl unit sits within the deployment housing unit and contains the vertical sonar head, catch hydrophone receiver, the optional forward hydrophone, the echo sounder 200kHz transducer and depth and temperature sensors. The mounting kit supplied contains the strain relief cable gland and other hardware used to attach the trawl cable to the trawl headrope.
The trawl cable is connected to the trawl sonar by a watertight connector and a locking sleeve. Commands are sent down the cable from the processors to operate the sonar. The sonar image and sensor data are sent up the cable to the processor and displayed on the appropriate monitor.

974-24007001/3.0 FS 70 Operators Manual Page 1.6 System Familiarization
1.1.7 Jointing Tool
Jointing tools and materials are required for splicing the trawl cable and attaching the trawl “2 pin pigtail” connector to the trawl sonar. We recommend using 3M 72-N1 jointing tool kits that can be purchase locally and especially designed for coaxial cable with a breaking point of 1500kg. The jointing kit will allow you to make 1 cable joint. Note: Proper joining and crimping sleeve will be required based on the type of 3
rd
wire you are using.
1.1.8 Catch Sensors
The catch sensor “eggs” are wireless sensors mounted on the cod-end of the trawl net to detect the stretch of the net as it fills up with the catch. When sufficient stretch of the net occurs, the catch sensor sends an acoustic signal to the trawl sonar through the catch receiver.
This information is then sent to the processor and displayed on the monitor. The sensors are of a rugged construction in order to withstand the strain from
winches and the power block. The operator can use up to six sensors (with the 40kHz system) simultaneously. The catch sensors are equipped with rechargeable batteries.
1.1.9 PI Sensors Option
The FS 70 provides full integration with the PI System, Door Spread, Bottom Contact, Rip Sensor and Cod End Depth Sensor available from Simrad Horten AS.
1.1.10 Depth & Temperature NMEA Output
The FS 70 processing Unit can be configured to output NMEA 183 data information. The integrated sensor module is included in the sonar head. The depth and temperature outputs are transmitted to the processor and displayed on the monitor. When interfaced to other Simrad echo sounders, the headrope depth information appears on the sounder showing the location of the trawl in relation to the fish or bottom returns.
1.1.11 Trawl Cable, Winch and Block
The trawl cable is chosen for maximum mechanical strength, durability and minimum attenuation of the signals. Cables in common use are coaxial with breaking points of 1500kg and 6000kg.
Port Coquitlam, BC - Canada
FS 70 Operators Manual 974-24007001/3.0 System Familiarization Page 1.7
Cable winches are delivered in different types and with different capacities; low­pressure hydraulic, high-pressure hydraulic and electrically driven. Choice of winch is dependent on prevailing conditions; type and length of cable and available source of power. Most types operate automatically - the cable is pulled out, kept tight during towing, and hauled in together with the trawl. Control of the winch is done remotely from the bridge.
Any commercially available pulley block may be used to properly align the cable onto the winch. A snatch block has the advantage that it may be installed without having to thread the cable through it. A unit with two movable steering arms (one on each side of the pulley) is recommended to prevent the cable from coming off the pulley and causing damage to the cable.
1.1.12 19” Rack Cabinet - 9U,
The Industrial Ventilated Rack Cabinet with a rugged black powder paint finish is an ergonomic design with ventilated slots front and side. The pre-punched top allows the installation of 2 fans. Cable accesses are available from the top or bottom.
The cabinet includes two pair of mounting rails, smoked glass door with full 180 degrees opening for easy access to the rack mounted equipment.
The overall dimensions are 19.8” (502mm) height, 23.6” (600mm) width, 24.0” (600mm) depth.

2. THEORY OF OPERATION
2.1 INTRODUCTION
This section explains the theory of operation of the Vertical and Sounder 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.
• An object in the path of the projected sound pulse will reflect some sound pulses back toward the sonar transducer.
• The speed of the sound pulse projected through the water can be predicted for given conditions.
2.1.2 Determining Target Position
The trawl scanning sonar processor measures the time from the start of the sound pulse projected through water, to the reception of the sound pulse reflected back to the sonar transducer. The measured time is then converted to distance by using the value of sound speed through water.
Since the sound pulse is projected in a known direction, the bearing of the reflected object is also known. This makes it possible to locate the object with respect to the sonar transducer; the information will be used to plot the position of the reflected target on a video graphic display monitor.
2.1.3 Forming an Image
The sound pulse projected will be attenuated as it travels through the water from the transducer to the target and back. Much of this attenuation is a predictable function of the total time or the distance the sound pulse traveled through water. Increasing the receiving gain with time can compensate for this decrease in the signal level. This is done automatically in the sonar with a Time Varying Gain (TVG) circuit.
Port Coquitlam, BC - Canada
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. Each sample is then plotted on the video display at the appropriate position according to its range and bearing. The level of the target strength sample determines the color used to plot each sample.
The process can be repeated with the transducer pointed in different directions, forming an image of a large area of the bottom, (or the trawl net geometry) and displaying it on the video screen.
In simple words, the TVG function controls the gain of the receiver so that a school with a given size and density is presented with approximately the same strength on the display, inside the regulated TVG range.
2.1.4 Key Feature Setting
The following paragraph will explain some of the key features of the FS 70 System.
2.1.4.1 AGC
Automatic Gain Control (AGC) The AGC “Automatic Gain Control” algorithm increases the gain during low acoustic
returns and reduces the gain during strong acoustic returns. The speed with which the gain is adjusted is determined by the setting of the “RX Gain Response”
2.1.4.2 RCG
Reverberation Controlled Gain (RCG) The RCG filter senses the noise level (reverberation, propeller noise, etc.), and
adjusts the gain of each of the received beams in order to eliminate noise on the display. The strength of the filter can be selected in the menu. With maximum strength selected, the RCG will effectively reduce the bottom in shallow water, while variation on the bottom will be displayed.
Note that scattered fish can be perceived as reverberation. The RCG filter must be used with care if scattered schools are to be detected.
Port Coquitlam, BC - Canada
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”. For the AGC, this setting determines the speed by which the gain is adjusted. For the RCG, this setting determines the influence of the previous ping average over the current ping. If set to Slow, the overall average is given by the sum of 20% current and 80% of previous average. In Medium this ratio is 50% to 50%, and in Fast the ratio is 80% to 20%.
2.1.4.4 Pulse Length Control
The FS 70 Trawl Sonar Heads are capable of changing the acoustic pulse length that is transmitted. The surface processing unit sets the pulse length based on the operating range of the sonar head. It is generally better to use a longer pulse as the operating range increases. However, the actual value can be optimized to enhance the details in the sonar image (Optimize Resolution) or to increase the target visibility at long distance away from the sonar head (Maximum Range). The system will automatically set the pulse length to match the range, unless manually adjusted by the operator.
2.1.4.5 Optimize Resolution
The pulse length selection can be optimized to enhance the detail of the targets. It has been experimentally determined that the pulse length corresponding to 40% of the sample period can increase the image resolution and details for targets that are generally larger than a few samples. This pulse length increases linearly with increasing operating range.
2.1.4.6 Maximize Range
The pulse length calculation can be optimized to increase the detection range of the sonar head. Generally, the longer the pulse length, the more energy is transmitted into the water which could then travel a longer distance and get reflected from the targets that are further away from the sonar head. It has been determined that the pulse length corresponding to 80% of the sample period can increase the detection distance of the targets without a major drain on the sonar head power supply. This pulse length increases linearly with increasing operating range.
Port Coquitlam, BC - Canada
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. The reason for this is that the combination of small target size, short pulse length and long sample period could result in the acoustic return from the target falling between two samples and therefore not beings seen on the sonar image.
To remedy this, it was decided to take additional samples and select the strongest echo target for the sonar image display. This is generally referred to as Peak Detection because we are detecting the peak value of signal in between two samples. The user can select the number of additional samples that the system takes in order to detect the peak value.

4.5.2 Final System Test
After preparing the trawl cable and before the final trawl unit assembly a system test should be conducted to insure correct operation of the FS 70 Trawl Monitoring System over the trawl cable.
As before, the start- up procedures should be followed to power up the system. Once the FS 70 has been turned on, the power supply voltage and current meters should be examined. Expected values are 0.2 – 0.5 (output voltage selection switch should be set to 200VDC. If the voltage and current values differ significantly from these values, it indicates a problem with the trawl cable or its connections.
If there are any errors during the calibration a status report page will appear containing the results that the control unit obtained from the tests performed. Again, any errors will be due to the trawl cable or its connections. Check the connections again and ensure that the signal polarity at the trawl unit is correct. A DC voltmeter can be used to check that the positive voltage is on the small pin of the pigtail when the FS PWR/TTM unit is powered up.
If all is okay then the sonar head will begin scanning and the sonar image display will appear.
4.5.3 Completing the Trawl Unit Assembly
First, the plastic cable strain relief supplied with the trawl unit must be bolted to the trawl cable. The location should be at or very near the pigtail splice, but NOT on the pigtail itself. You must slide the rubber hose on the trawl cable, if used, down so that approximately 3-4 cm (1-2") of the hose is clamped inside the strain relief.
Next, the trawl cable is connected to the sonar head. Liberal amounts of Dow Corning #55 grease are applied to the connector surfaces before mating so that a water tight seal is obtained. The locking sleeve is then hand-tightened.
Note!
Dow Corning #55 grease must be applied to all mating surfaces of underwater connectors to insure proper sealing. Sufficient grease should be applied so that excess squeezes out with any air when the connectors are mated. RTV or any other sealant must NOT be used, and when tightening the locking sleeves do NOT use a wrench or pliers! See chapter 5, "Troubleshooting and Maintenance", for proper connector maintenance.
The plastic strain relief attached to the trawl cable is now placed in the trawl unit housing containing the electronics and the excess cable is routed in the housing as shown in Chapter 6 “Drawings”. Care must be taken to insure that all cables within the
Port Coquitlam, BC - Canada
FS 70 Operators Manual 974-24007001/3.0 FS 70 Installation, System Set-Up and Test Page 4.27
trawl unit housing are properly placed to avoid being pinched and possibly damaged. The top half of the trawl unit housing is then placed on top and the two halves are secured together with the bolts supplied. Finally, the dome is secured over the Vertical Sonar Head transducer with four additional bolts.
The fully assembled trawl unit is now ready for mounting to the trawl headrope in the chosen manner.
4.5.4 Mounting CATCH SENSORS
Proper mounting of the catch sensors on the cod-end is shown in drawing # 830­056482 (see chapter 6, “Drawings”).
The fill of the cod-end and the sensitivity of the sensors is dependent upon the number of mesh knots between the catch sensor and the rubber straps. Make sure that the sensor is mounted in the correct direction with the transducer pointing towards the trawl unit (the metal lid pointing aft).
Caution! Make sure that the chains do not strain the net when the cod-end is being filled with fish. This is controlled by stretching the net to capacity in the direction which is relevant AFTER THE SENSORS HAVE BEEN MOUNTED TO THE TRAWL.
The purpose of the chains is to prevent the sensor from turning, and as an insurance against loss should the rubber straps break. Mounting the chains too tight can result in the fastening ears being ripped off.
If a system with four catch sensors has been ordered, sensors numbered 1 and 2 can be used on the trawl and the other two sensors kept for reserve.
For deep trawling, and when fish are abundant, it can be advantageous to mount three or four catch indicators in such a way that cod-end filling can be monitored continuously to insure that the trawl is hauled back in time.

5. TROUBLESHOOTING AND MAINTENANCE
5.1 INTRODUCTIONS
This document is provided to instruct in the proper handling, maintenance and troubleshooting of the FS 70 Trawl Monitoring System.
5.2 SYSTEM OVERVIEW
The Simrad FS Trawl Monitoring System FS 70 consists of wheelhouse electronics and a trawl unit. The wheelhouse electronics include the display unit, the FS Processing Unit, and the PWR/TTM interface unit. The trawl unit electronics include the sonar head with a integrated sensor module, receiver transducer, and up to four catch sensors and door spreads sensors. 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.
5.2.1 FS 70 System
The FS PWR/TTM unit contains the power modules to provide the Test Voltage, the 120 and 200 VDC @ 1 A maximum for powering the trawl unit electronics, and the voltage and ampere meters. The low-frequency telemetry adapter “LF 1” Low Frequency PCB and the telemetry translation module “TTM” PC interface is now incorporated into one unit.
With the FS 70 system, the trawl cable connects directly to the PWR/TTM unit. Furthermore, the compensation for signal loss over the long trawl cable is done automatically within the Processor Unit each time it is powered up. In this way changes to the cable loss do not affect the intensity of the sonar return displayed.
5.2.2 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 <100 ohms Signal Attenuation Through Cable: <40 dB (1/100 signal amplitude) @ 55 kHz <20 dB (1/10 signal amplitude) @ 12 kHz
Port Coquitlam, BC - Canada
974-24007001/3.0 FS 70 Operators Manual Page 5.4 Troubleshooting and Maintenance
The cable closed loop resistance determines the maximum voltage drop along the trawl cable. For proper operation the FS 70 trawl unit electronics require 200 VDC @ 1 A maximum. For typical operation, the current is approximately 350 mA with peaks to 500 mA. The equations for calculating the voltage drop along the trawl cable are:
Voltage Drop Along Cable = (Cable Resistance) x (Current through Cable)
i.e. Current = 300mA, Voltage at the head +180vdc,
therefore calculated Resistance = 180V
0.3A Example: TTM set at 200Vdc
Voltage at head 180Vdc Amp meter (0.3)
R = 200 - 180
0.3A This results is 66.67 ohm The cables allowable closed loop resistance is 100 ohms.
5.3 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.
3. Excessive impacts and/or physical damage to trawl unit electronics.
In all three of these cases, proper handling and maintenance can significantly reduce the frequency of FS failures.
The following sections outline the recommended handling and maintenance for the FS system.
5.3.1 Wheelhouse Electronics
Once installed these units require little maintenance other than removing dust. A damp, lint-free cloth should be used for this purpose.
Port Coquitlam, BC - Canada
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. Care should be taken at all times to avoid dropping or impacting the trawl unit or the individual components.
• Avoid scratching
the surface of the sonar head housings. The anodized surfaces (black coating) are there to protect the electronic housings from corrosion and any damage to these surfaces will increase the likelihood of corrosion.
• Ensure correct installation of the sonar head into the trawl housing to avoid improper operation. A locking block is located at the end cap to secure the sonar head into the lower part of the housing.
• Protect connector mating surfaces from corrosion and damage. At the first sign of damage, connectors should be replaced!
• Pigtails must be properly attached to the trawl cable and the connector mating surface must be protected from moisture and dirt at all times. Failure to do this may result in water damage to the cable causing improper operation of the sonar system.
5.3.2.2 Maintenance Schedule
For optimum performance and trouble free operation, follow the maintenance schedule below.
• Beginning of Fishing Season
Service all connectors
• Every Two Weeks of Continuous Use
The trawl unit package should be opened and the components cleaned with fresh water. The trawl sonar head should be inspected for corrosion or damage. Service all connectors. The FS processor should be checked and cleaned if required.
• End of Fishing Season
The trawl unit package should be opened and the components cleaned with fresh water. The trawl sonar head should be inspected for corrosion or damage. Service all connectors and cover them with plastic. Store unit in a dry, clean area.
Port Coquitlam, BC - Canada
974-24007001/3.0 FS 70 Operators Manual Page 5.6 Troubleshooting and Maintenance
• Every Twelve (12) Months Heavy usage or Every Two Years
Return the trawl sonar to a qualified Simrad service facility for inspection of connectors, seals and shaft assembly. Have parts replaced as required.
• Every Four Years
The trawl sonar head should be returned to a qualified Simrad service facility for recalibration and upgrade to the latest specifications, and inspection of connectors and housings for damage.
5.3.2.3 Connector Maintenance
Proper connector maintenance is crucial to the prevention of connector failure that may result in failure of the sonar system and possible water damage to the sonar head. The following steps should be taken whenever the connectors are assembled, or at regular intervals as outlined in the “Maintenance Schedule” section above.
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. Apply liberal amounts of Dow Corning “55” grease to each of the connector prongs and to the sealing surfaces of the connectors. Do not use a silicone rubber adhesive sealant!
4. Press connectors together until fully seated. Excess grease should be squeezed out of the connector sockets.
5. Hand tighten the locking sleeve. Do not use a wrench or pliers!
6. When separating the connectors, avoid wrenching or bending connector.
Caution! Failure to correctly maintain connectors may cause damage to the system and will void the warranty.
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.
Excessive impacts to the trawl unit usually result in physical damage to this housing. However with the newer, more durable urethane housing, excessive impacts to the trawl unit may NOT cause physical damage to either the trawl housing or the exterior of the individual electronic units, but may result in damage to the electronics.
Port Coquitlam, BC - Canada
FS 70 Operators Manual 974-24007001/3.0 Troubleshooting and Maintenance Page 5.7
Note! As with all electronics, careful handling of the trawl unit will reduce the likelihood of FS failures.
5.3.2.5 Corrosion
If on examination corrosion has occurred to the sonar head metal parts these areas should be cleaned well and the area sealed with paint or a sealant to prevent continuation of the corrosion in this area.
Caution!
If corrosion is allowed to continue, flooding of the unit may result.
5.3.2.6 Shaft or Transducer Damage
The transducer and shaft are protected by a flexible dome and should be inspected for damage. If the transducer dome has experienced an impact this could bend the shaft and eventually allow water into the housing. If the shaft is bent the unit should be returned to a qualified Simrad service facility for replacement of the shaft seal assembly.
Note! If the sonar head is correctly installed in the trawl unit, with proper placement of the locating block, then damage to the transducer and shaft should not occur.
5.3.3 Catch Sensors
The catch sensors are relatively maintenance free except to charge the batteries. Refer to your Simrad FA701 and or PI 32 Catch sensors 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.
5.3.4 Winch Slip-Rings and Trawl Cable
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 slip­rings will degrade the performance of the system and may cause or lead to a complete system failure.
Port Coquitlam, BC - Canada
974-24007001/3.0 FS 70 Operators Manual Page 5.8 Troubleshooting and Maintenance
Worn, dirty or wet winch slip-rings may add noise, current spikes or additional losses to cable. Slip-ring assemblies should be checked regularly for wear and proper sealing against the weather. Slip-ring technology has improved considerably over the past several years and sealed units from several suppliers (such as IEC Corp.) have proven to be very reliable.
Trawl cables, particularly the plastic jacketed type, are extremely susceptible to damage and wear that may adversely affect system operation. Proper maintenance is very important to ensure cable losses are minimized and adequate isolation between the cable conductors and sea water are maintained. Common problems include poor splices, water damage, cracked or worn outer casing (insulating jacket), or severed cable. The trawl cable should be routinely checked for damage and affected sections removed, splices redone or the entire cable replaced as required.
The pigtails spliced to the end of the trawl cable are susceptible to damage and corrosion and must be checked and if necessary replaced every time prior to connecting the trawl unit. When not in use the pigtail should be wrapped in a plastic bag and stored, out of the weather and away from being stepped on or damaged in any other way.
Polarity of the signals applied to the trawl cable (coax) may also be important in the proper operation of the system. To provide optimum shielding from noise, we recommend the positive signal be applied to the center conductor and the negative signal to the shield.
For additional information on connecting to slip-rings and examples of splicing trawl cable refer to Part 7 “Drawings”.
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. 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. This can be valuable in detecting problems before they cause an FS system failure.
5.4.1 Test Cable
With every FS Trawl Monitoring system, a 50’ test cable is supplied for testing the system without requiring the trawl cable. This provides a quick and simple way of verifying whether problems are due to the trawl cable or winch slip-rings. In addition system performance values that are measured on the test cable provide a base for later comparison (using either the test cable or trawl cable).
Port Coquitlam, BC - Canada
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. Refer to Part 6 “Drawings” for more information and interconnection drawings.
When using the test cable the power supply voltage can be set to “OFF” no voltage on the trawl cable, to “TEST” (60 VDC) or 120 VDC). If the system is to be operated for extended periods on the test cable, then the power supply voltage should be set to “TEST”.
5.4.2 Power Supply Meter Readings
The voltage and ampere meters are useful for monitoring the trawl unit power requirements. For the most benefit, these meters are mounted on the front panel of the PWR/TTM unit next to the trawl voltage selection switch for continuous monitoring.
When the system is first installed or when the trawl cable is replaced the trawl cable voltage selection switch should be set to 200VDC and current values should be recorded when the unit is running in normal operating mode (i.e., with range and scan speed set to values normally used during fishing). Typical values are 200 mA to 350 mA for sonar heads. To facilitate monitoring of this information these values should be recorded on the charts provided in Part 6 “Drawing”.
Any changes in the recorded meter values during normal operation may indicate a potential problem even if the unit continues to operate properly. Common cases are:
1. Current Meter Jitters This is commonly due to dirty, wet or worn winch slip-rings that cause current spikes on the trawl cable when the winch is rotating.
A test for slip-ring problems is to slow down the winch (at high winch speeds you will not see jitter on the current meters) and check if the current meter is jittering and whether the jitter rate changes with the winch speed.
2. Increase in Current Gradual increases in the trawl unit current may be due to either the trawl cable or the trawl unit electronics. A higher cable closed loop resistance, due to cable damage, poor splices, poor winch slip-rings or water in cable may reduce the voltage supplied to the sonar head below the required minimum of 60 VDC. This will result in the sonar head drawing more current. Alternatively, there may be a problem in the sonar head that causes additional current draw.
To diagnose this problem, a current reading should be made with the system
Port Coquitlam, BC - Canada
974-24007001/3.0 FS 70 Operators Manual Page 5.10 Troubleshooting and Maintenance
running on 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.
5.4.3 Trawl Cable Gain
When signals pass through cables, the signal is attenuated by a certain amount that is normally dependent on the type and length of cable used. For the FS Trawl Monitoring system to operate properly it must apply gain to the signals to compensate for the cable losses. Monitoring of this required gain allows the trawl cable to be checked for additional losses due to damage, water, poor splices, bad connectors, etc.
With the FS 70 system the cable compensation gain has been automated. Each time the system is powered up (or when a system calibration is performed) the gain is set in the processor unit by monitoring the transmit pulse from the sonar head and increasing the gain until the received signal is normalized to a standard level (that is why you hear the transducer pinging just after turning the system on). The resulting gain is displayed in the system test result page as two integer values separated by a colon. Each value is an integer from 0 to 255 with a larger value corresponding to higher gain.
By periodically checking the cable compensation gain obtained from the FS unit and comparing it to a previously recorded value the condition of the trawl cable can be monitored. Acceptable cable gain values have less than 100 for the first gain number. If the first gain value is over 200 then there may be a problem with the trawl cable and the system should be checked on the test cable. To facilitate monitoring of the trawl cable, the cable gain values should be recorded on the charts.
5.4.4 Telemetry Errors
In the normal operation of the FS Trawl Monitoring system commands are sent from the processor unit down the trawl cable to the trawl unit electronics and acknowledgments are then sent back up to the processor unit. Rudimentary error checking of these commands is performed to monitor the performance of the telemetry.
Telemetry errors can result from noise induced on the trawl cable due to interference or problems with the trawl cable or trawl unit electronics. Though a few telemetry errors are quite common and acceptable, an excessive number of errors will adversely affect the sonar operation and may indicate a problem that will eventually cause a system failure.
Port Coquitlam, BC - Canada
FS 70 Operators Manual 974-24007001/3.0 Troubleshooting and Maintenance Page 5.11
A common occurrence of telemetry errors is time-outs. This problem indicates the trawl unit electronics are not responding to the processor unit or the integrated sensor module is not responding to the sonar head. The causes of this are either with the electronic units themselves or with the trawl cable or interconnect cable. Typically, if the problem is with the sensor module or interconnect cable, the time­outs occur in multiples of 15 (the sonar head may still operate correctly with the exception of periodic pauses).
5.5 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 slip­rings, the interconnect cable or the trawl cable. The following sections provide helpful advice on troubleshooting the FS system.
5.5.1 System Tools
The system tools available for troubleshooting the FS system are:
1. Test Cable Provided with every FS Trawl Monitoring system, the test cable enables the FS system to be tested without the winch slip-rings or test cable. This provides a quick and simple means of checking whether the problem is with the FS electronics or not.
2. Power Supply Unit Voltage and Current Meters The power supply unit meters allow the trawl cable voltage and current to be continuously monitored. When a fault is detected the meter values should be noted and current meter behavior observed. Jitter in the current meter may indicate current spikes due to the winch slip-rings. Higher or lower values than normal (typical values: 110 VDC, 250 - 350 mA) may indicate additional losses in the trawl cable due to physical or water damage, bad splice, etc., or problems with the trawl unit electronics.
3. Processor Unit Calibration or Self Test Routines The FS 70 processor unit has calibration or self test routines for checking system performance. The SELF TEST MENU contains several items for checking the gain and then displays it along with the current status of the other system test value. Other useful selections include “Calibrate” for performing a complete system calibration, and “Telemetry Test” which repeatedly sends commands to the sonar head and reports all telemetry errors in real-time. Results obtained from these routines may indicate noise problems or additional losses in the trawl cable, or problems with the trawl
Port Coquitlam, BC - Canada
974-24007001/3.0 FS 70 Operators Manual Page 5.12 Troubleshooting and Maintenance
unit electronics. The usefulness of these tools is greatly enhanced when they are used on a
regular basis to monitor system performance. Records of past system performance (when the unit is operating properly) provide a basis for comparison that may assist in diagnosing the problem when an FS system fails.
5.5.2 Diagnosing Problem
If the FS system develops a problem, or if it fails completely, the steps below should be followed.
1. Check the power supply unit meters and record their values. If the failure was on
power up, ensure the voltage selection switch is on high and that the power is on. If the system developed a problem or failed while operating, then note the voltage and current meter behaviors. If the current meter jitters, then stop the trawl winch if rotating, and note any changes in the meter values or their behavior.
2. If the processor unit displays a system test result page then record the values
and make note of any failure (highlighted in red). If not, then implement a system test and record the results obtained.
3. Disconnect the trawl unit from the trawl cable and re-connect to the FS system
using the test cable. 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.
The following list common problems and probable causes Problem Action/Possible Cause
1. Complete system and/or calibration failure - cable gain at max., telemetry errors head id + 1, etc.
− Check power supply unit voltage and current, ensure unit is on (voltage meter at 200 VDC). If current okay, then sonar head needs replacing.
− If no current, then check trawl unit on test cable. Trawl cable or slip-rings at fault if unit runs fine. If not, then
Port Coquitlam, BC - Canada
FS 70 Operators Manual 974-24007001/3.0 Troubleshooting and Maintenance Page 5.13
replace sonar head.
2. Sonar head operates okay, but pauses periodically - may not have sensor module data
− Check for telemetry errors. If none, then problem with sonar head or processor unit.
− If errors and they occur in multiples of 15, then the internal sensor module is defective. Check by restarting the system.
− If errors, check system using test cable. If errors go away, then problem with trawl cable or slip-rings, otherwise problem with sonar head.
3. Sonar head operates okay, but image skewed or distorted.
− Check calibration for errors in sonar head positioning. If errors, then problem with sonar head, otherwise check that sonar head is properly mounted in trawl housing.
4. Sonar head operates okay, but cable gain higher than normal and possibly telemetry errors.
− Check system on test cable. If gain okay and errors go away, then trawl cable or slip-rings faulty, otherwise problem with sonar head.
5. No sensor module data.
− Internal sensor module electronics is defective.
6. No catch indication, but depth and temp okay
− Ensure catch sensors are properly charged and display of catch data is enabled.
− Check unit on deck with catch sensor placed 1 meter from receive transducer. Connect wire from “+” lug to metal lid on back of catch sensor, wait a couple minutes and verify display. If no indication or indication is wrong, then fault with the internal sensor module.
5.5.3 Testing Trawl Cable
If after testing the FS system the trawl cable is suspected to be faulty, then troubleshooting is needed to determine what and where the problem is. For problems that are not obvious, however, this can be quite difficult to do and may require someone experienced with testing trawl cables. This section provides some basic tips in troubleshooting trawl cable but is in no way a complete and comprehensive guide.

5.5.3.1 Cable Impedance
The use of a Meggar to check the impedance of the trawl cable may be the most useful test. It can be done with or without the slip-rings connected and readings should be taken between the cable’s two conductors and also from each conductor to the fishing vessels hull. As a minimum, the impedance should be greater than 2 Mohms, and preferably over 6 Mohms.
Caution! The FS system MUST be disconnected from trawl cable during Meggar tests to prevent possible damage to the electronics!
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).
5.5.3.2 Closed Loop Resistance
As previously mentioned, the closed loop resistance must be less than 100 ohms for proper operation of the FS system. This test should be done with the FS system disconnected but with the winch slip-rings included.
To do the test the conductors at one end of cable should be jumpered together (shorted). An ohmmeter is then used at the other end of cable to measure the resistance between the conductors.
5.5.3.3 Voltage and Current at Trawl Unit
A further check of the cable losses can be done by measuring the voltage and current at the trawl unit. This measurement requires the trawl unit electronics to be connected and the FS system powered up. This test is done where the trawl cable pigtail plugs into the sonar head. Jumpers will be required to breakout the signals for connection to voltage and ampere meters.
Caution! There are DC voltages on the trawl cable that are capable of
delivering a lethal electric shock!

5.5.3.4 Test for Water In Cable
When a trawl cable is damaged or there is a poor splice, sea water can get into the cable. As a result, the cable may act as a battery - producing a small dc voltage across the conductors of the cable. This is detrimental to the operation of the FS system and all affected cable should be removed.
To test for this the trawl cable should be disconnected from the FS system and a voltage meter connected to the trawl unit end of the cable. If water is present, then there may be a reading of 2 - 3 volts dc.
5.6 SECTION 1 - CATCH SENSORS
Refer to your Simrad FA701 or PI32 sensor operator and service manual.
5.7 SECTION 2 - WINCH SLIP-RINGS AND TRAWL CABLE
Refer to your Manufacture operator and installation manual.
5.8 SECTION 3 – DIAGNOSTIC RECORDINGS
The system will save your screen displays in three different ways. Two of these ways are manually started by the operator and the third is automatically managed by the system. All three methods create files on the system which can be sent to your service provider for analysis.
5.8.1 Snapshots
The system will allow you to save snapshots of the screen display. In the lower right hand corner of the display you will see the following display
To take a snapshot of your display simply left click on the camera icon. A snapshot will be saved in the “diagnostic” folder. When you click the camera icon a grey message box will appear in the top left hand side of your display stating ”Saving a sonar image. Please wait.” This box will only appear for a second or two but
Port Coquitlam, BC - Canada
974-24007001/3.0 FS 70 Operators Manual Page 5.16 Troubleshooting and Maintenance
confirms that you have taken a picture and that it has been saved. The snapshot saved will be only of the active window on your display – either the vertical head or the sounder. The system saves both a video picture of your display and a text file listing all of your system settings.
5.8.2 Manual Recordings
You can, at any time, start a recording of your display. To do this left click on the red button beside the camera icon (see image above). This recording will continue until you stop it by clicking on the same button again. These recordings are saved into the “record” folder.
The traditional way of starting a recording also still exists on the system. Refer to section 3.2.13 of this manual. Go to the display toolbar and turn the Record Toolbar on. The traditional recording toolbar will appear on the left side of your display. You will also use this toolbar to playback any of your recordings.
5.8.3 Automatic Recordings
The system is also automatically recording your display without the need for you to do anything at all. The reason for this background recording is to ensure that should you experience difficulties or an error the system will have kept a recording of it for future analysis. This file can then be sent to your service organization for analysis. This file is a four hour recording that continually loops itself ensuring that there is always a recording of the last four (4) hours of operation. These files are saved into the “diagnostic” folder.
Port Coquitlam, BC - Canada
FS 70 Operators Manual 974-24007001/3.0 Troubleshooting and Maintenance Page 5.17
5.8.4 File Transfer Procedures
To access any of the files that have been saved go to the following directory in your system:
C:\ programs\KML\FS70 VO1.70
You will see the folders for “diagnostic”, “LOGS” and “Record”. Your recordings files are saved as follows:
Diagnostic folder: Any snapshots that you take The auto-run four (4) hour recording
LOGS folder: System messages and error messages (automatic) Record folder: Any recordings that you manually start
All of these files are date and time stamped so you will know exactly when they occurred.
If you have experienced a problem with the system you want to ensure that the auto recording of the event will not be overwritten. In this event you want to simply move the file from the “diagnostic” folder and place it into a folder where you will easily be able to find it. This file should be sent to your service provider at your earliest convenience so that they can help determine what has caused the problem.
