System familiarization 1 INTRODUCTION The Simrad SD 570 sonar is a medium range omnidirectional sonar, designed for small, medium and large sized fishing vessels, both purse seiners and trawlers. Great emphasis has been placed on giving the best possible presentation on the 14” high--resolution colour display. The result is 9 different display modes, which gives a flexible choice for a large range of user applications. The transceiver system contains an advanced multifrequency filter system (FM).
Simrad SD570 2 2.1 SD 570 UNITS Introduction Figure 1 shows a system diagram for the SD 570 sonar, and as can be seen, it consists of only three main units: · Sonar Control Unit · Transceiver Unit · Hull Unit A short description of each unit will be given in the following chapters.
System familiarization Figure 1 - SD 570 Sonar system diagram 850--160137 / A 3
Simrad SD570 2.2 Sonar Control Unit The Sonar Control Unit comprises a 14” display unit, a control panel, a loudspeaker and a computerized electronic unit, all housed in one console. The complete operation of the sonar system is performed from this unit. Figure 2 - SD 570 Sonar Control Unit The display is a 14” raster--scan high--resolution colour CRT, creating a stable and flicker--free picture. In addition to the sonar picture, the CRT also displays the user menu for the interactive operation.
System familiarization The computerized electronic unit is located in the bottom section of the console, and performs the following functions: · Interfacing of the control panel · Interfacing external connections (log, gyro, etc.) · Generating the total display presentation · Generating the audio of the echo signal · Controlling the serial line communication to the transceiver The loudspeaker, which is mounted inside the electronic unit, reproduces the audio of the echoes for the selected audio channel.

System familiarization 2.4 Hull Unit The SD 570 Hull Unit is designed to be lowered 1.0 meter below the ship’s hull at a maximum ship’s speed of 15 knots. The transducer can also be lowered to a middle position where only the transducer face is outside the sonar trunk.
Simrad SD570 2.5 Auxiliary equipment The SD 570 sonar requires connection to a speed log and a course gyro. An inaccurate log or gyro input will cause inaccurate indication of the vessel and target movements. In addition to log and gyro, the following auxiliary equipment can be connected to the sonar: · Simrad echo sounder, types EQ 50, EQ 55, EQ 100, ES 380/700 or ES 500. Gives depth readout in the menu and a bottom plot on the catch data page. · Simrad Trawl Instrumentation: FS 900, FS 3300 or ITI.
System familiarization 3 3.1 FUNCTIONAL DESCRIPTION Introduction The basic principles of the SD 570 sonar are unique because of the 256 separate transmitter and receiver channels with their transducer elements spread around on the transducer array. The transmission, reception and data processing are under computer control, and the powerful capabilities of the sonar are results of sophisticated digital signal processing software and state of the art hardware. 3.
Simrad SD570 Figure 5 - OMNI/Vertical combination The combination of the OMNI mode and the vertical slice, will give an optimal visualizing of the catch situation. In addition to the OMNI picture, the vertical slice is especially useful for visualizing the vertical distribution of a school of fish. In that way, it is not necessary to go over the target to see the distribution on the echo sounder, which often results in a spreading of the school.
System familiarization 3.4 Receiving A great effort has been made to reduce unwanted noise to get a clean and stable echo presentation. To achieve this goal the sonar receiver has the following filtering possibilities: BANDPASS FILTER One hardware filter for each preamplifier with a bandwidth of 1500 Hz to reduce interference and noise from signals outside the sonar frequency. FM CORRELATION FILTER See description in paragraph 3.3.
Simrad SD570 TVG (Time Variable Gain) 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. This can also be seen as a filter, because it reduces the noise close to the vessel. The regulated strength of the TVG can be selected in the menu.

Modes of operation 1 INTRODUCTION All operation of the sonar is made from the Sonar Control Unit. This section contains a detailed description of the different modes of operation. The man--machine interface, the normal start/stop procedure and the menu operation is described in section ”Operation”. In order to get the necessary understanding of the sonar working principle, read first through section ”System familiarization”. Note that the SD 570 transducer in its lower position reaches 1.
Simrad SD570 2 2.1 MODES OF OPERATION General Great emphasis has been placed on giving the best possible overview presentation of the echo situation of the water volume around and under the vessel. The result is 9 different display modes, which gives a flexible choice for a large range of user applications. The mode selection is made in the menu, and a detailed description of each mode will be given in the following chapters.
Modes of operation 2.2 Bow up In this mode the ship symbol is stationary in the centre of the screen, with the bow pointing upwards. The echo presentation can cover 360 degrees around the ship, and if OMNI is selected, all echoes will be updated for each ping. The distance from the ship symbol to the echo ring is equal to the selected range. Figure 1 - Bow up The movement of the echoes across the screen will be a combination of the ship’s course and speed and the targets’ own movement.
Simrad SD570 2.3 North up In this mode, true north is always up on the screen, and the ship symbol is stationary in the centre of the screen with the bow pointing in the direction of the ship’s course. Figure 2 - North up The echoes will also here move across the screen relative to the ship’s course and speed, and, as indicated in the figure, a course line after the ship and target can be displayed. The ship’s course and speed, and the date and the time are shown in the bottom of the menu field.
Modes of operation 2.4 True motion In true motion the picture is locked to a geographical position, with true north up, as shown in figure 3. Figure 3 - True motion The ship symbol moves around on the screen according to the course and speed readings. All echoes are always in correct position relative to the ship, and their movements on the screen will be a true representation of the movements of the targets through the water.
Simrad SD570 2.5 180°/Audio In this mode the upper half of the screen shows a 180° bow up presentation, while the lower part is used for a recording of the audio channel. Figure 4 - 180°/Audio The audio channel is shown with a continuous white line in the horizontal picture, and can be trained in any direction. The recorded echoes are a direct replica of the echoes under the white audio line.
Modes of operation 2.6 180°/Echo sounder In this mode the upper half of the screen shows a 180° bow up presentation, while the lower part is used for an echo sounder recording. That means that the sonar acts alternately as a normal sonar and an echo sounder for each second transmission. Figure 5 - 180°/Echo sounder When selecting this mode, the lower half of the screen will be dark. A recording will then be built up from right to left on the screen, and store the last 512 transmissions.
Simrad SD570 2.7 180°/Vertical In this mode the upper half of the screen shows a 180° bow up presentation, while the lower part is used for a vertical slice presentation. In that way an echo can simultaneously be presented in both horizontal and vertical dimensions. Figure 6 - 180°/Vertical The bearing of the vertical slice is indicated in the horizontal plane by the white audio line, and can be trained to any bearing by the manual training knob.
Modes of operation 2.8 270°/Vertical This mode is specially made for purse seining, where the vertical half slice is displayed in the lower left corner for normal setting of the net on starboard side. If the net is selected to be set on the port side, the vertical half slice will be displayed in the lower right--hand corner.
Simrad SD570 2.9 Omni/Vertical This mode is specially made for trawling, where a complete overview of the horizontal and vertical situation is presented. Figure 8 - Omni/Vertical The bearing of the vertical slice on the right--hand side is as in 180°/Vertical mode indicated by the white audio line, while the slice on the left--hand side in this mode is indicated by a long--dashed line.
Modes of operation The catch data page for trawling is selected in the menu field. Here the trawl position is presented in relation to the target, and this can be used as a sight in order to optimize the catch. In addition to showing the trawl position this page also shows all available target data. A detailed description of this catch data page is given in chapter 5.27 in section Operation.
Simrad SD570 2.10 Omni/Echo sounder This mode is also specially made for trawling, but in this mode the trawl--locked vertical slice is replaced by an echo sounder recording. This to ensure a more correct depth indication in case the sonar beam is bent because of temperature layers. Figure 9 - Omni/Echo sounder In order to get the school presented in the echo sounder recording, the vessel must here pass over the target.
Operation 850- 160139 / AA000 / 3- 14 SD570 Operation This section contains description of all control knobs and menu commands of the SD 570 sonar, as well as start and stop procedures.

Operation 1 1.1 MAN--MACHINE INTERFACE General The operating controls are located on an easily- operated control panel. As some of the functions on a sonar system are in more intensive use than others, these have their own control knobs arranged in function groups, as tilt, train, etc. The other functions are ”menu- oriented”, controlled by a single joystick. The menu is displayed on the right- hand side of the display.
Simrad SD570 1.2 The main control panel Figure 2 shows the main control panel. The following pages give a detailed description of each function, and for an inexperienced operator it is recommended to try the functions on an operative sonar while reading this chapter.
Operation 1. CURSOR JOYSTICK This joystick is used to move the yellow cursor (+) on the display, and can be used for the following purposes, which will be described thoroughly for each function later in this chapter: · Distance, bearing and depth indication for any position on the screen, with the readouts in yellow figures in the upper right- hand corner (lower corner for omni/vertical modes). · Target marker positioning when using the TARGET MARKER push button.
Simrad SD570 2. MAIN SWITCH The main switch controls the mains power to the sonar, the lowering and hoisting of the transducer, and indicates the transducer position. Note ! Before lowering the transducer, check that the depth of water below the vessel is sufficient, and that the vessel’s speed is below 15 knots. This is the maximum speed specified with the transducer lowered. ON- OFF In order to start up the sonar, press the ON- OFF/HOIST button for approx. two seconds.
Operation TRANSDUCER POSITION In addition to the indicated transducer position on the upper line in the menu field, the lights in the ON- OFF/HOIST and LOWER buttons will also indicate the transducer position: · The ON- OFF/HOIST button lights with the transducer in UPPER position. · The LOWER button lights with the transducer in LOWER position. · No button lights with the transducer in MIDDLE position. · Both buttons lights when the transducer is hoisting or lowering.
Simrad SD570 3. DISPLAY- ORIENTED PUSH BUTTONS TARGET MARKER To set a target marker, move the cursor to the target and press the button. A triangle symbol with a corresponding number will then appear at the cursor position. 8 numbered target markers may be shown simultaneously. When more than 8 markers are positioned, the oldest one is erased. The position data for 8 markers is displayed in the MARKERS menu. The sonar keeps track of the markers even outside the display.
Operation GEAR SYMBOL The gear symbol can be a seine circle or a trawl symbol, depending on the selection in the GEAR menu. Seine circle: To set a seine symbol, first press the GEAR button once. The button lights, and the seine circle appears in front of the ship symbol, on the side that is selected in the GEAR menu. The seine circle will now follow the ship’s movements. At the moment the setting of the seine starts, press the GEAR button again.
Simrad SD570 This button has three functions: QUICK MODE SELECTION Pressing this button in bow up mode gives a quick change to the 270° /vertical mode. This can be used for easy evaluation of the target, or for preparing the catching phase. Next operation of the button brings back the bow up mode. DISPLAY CENTRE In true motion mode, a new position of the ship symbol can be selected by moving the cursor to the wanted new position, and then pressing the button.
Operation 4. GAIN CONTROLS VOLUME The two upper push buttons control the volume of the audio channel in the loudspeaker. The audio channel is shown with a continual white line, and can be trained by the train controls. Also note that the size of the audio sector can be changed from 11° to 99° in the menu (chapter 5.10). MAN/AUTO GAIN These two push buttons are used to simplify the ON/OFF selection of the AGC and the RCG. The selection adjusts the AGC and the RCG to the following menu settings: AGC........
Simrad SD570 5. RANGE CONTROLS The selected range is displayed in the upper right- hand corner of the display. The ranges are: 125, 250, 375, 500 , 750, 1000, 1500, 2000, 3000 and 4000 meters. To make an optimal position tracking or target tracking programme, the range selection will go to AUTO when selecting these modes. To keep a steady display picture during seine setting, the lower automatic range is set to 400 meters. Changing the range or pressing the MAN button will stop the auto- ranging.
Operation 6. MENU JOYSTICK This joystick controls the menu operation, and can be moved in four directions: up, down, left and right. The up and down movement is used to move the menu cursor (inverted video) up and down in the menu, and the left and right movement is used as an ENTER function. When the menu cursor is in the main menu or the extra menu, and the menu joystick is moved to the left, a catch data page will appear in the menu field.
Simrad SD570 7. TILT CONTROLS The tilt can be adjusted electronically from +10° to - 90°. The tilt angle is normally repeated on the tilt indicator in the upper left- hand corner, but in some of the dual modes, the tilt angle is shown directly in the vertical slice. MANUAL TILT In manual mode, the transducer may be tilted within the limits of +10° to - 90° by pressing the tilt up or down push buttons.
Operation 8. ILLUMINATION These buttons controls the backlights and signal lights in the push buttons. In broad daylight only the signal lights may be selected by pressing the + button for maximum light and then releasing the button and giving it a new short press. Then only the signal lights will light up with maximum light. 9. TRAIN CONTROLS The audio channel is shown with a continuous white line, and can be trained manually or automatically.
Simrad SD570 POSITION TRACK This tracking programme is only fully activated when both course gyro and speed log are connected to the sonar system. Place the cursor on the position to be tracked and press the button. A geographically fixed circle is then displayed, and the sonar will automatically track this position. The track sector angle is set by the SEARCH SECTOR buttons.
Operation 2 THE MENU SYSTEM The menu is displayed on the right--hand side of the display. In order to make an optimal use of the sonar for most types of operation, three different menus may be selected (refer to chapter 5.18.4). The table below shows the contents of the main menu for the different submenus, with reference to the chapter in which the submenu is described. MAIN MENU REFER TO CHAPTER SHORT NORMAL & FULL MODE MODE 5.1 PULSE FORM TX POWER PING SECTOR 5.2 5.3 5.
Simrad SD570 If the cursor is moved below PP FILTER in the main menu, an extra menu will appear at the bottom of the menu field. This information is normally hidden because these functions are seldom used, and the system is more easily operated with an uncluttered screen.

Simrad SD570 4 START AND STOP PROCEDURES 4.1 Start procedure Note ! Before starting up the sonar, check that the depth of water below the vessel is sufficient, and that the vessel’s speed is below 15 knots, which is the maximum speed specified with the transducer lowered. The numbers in brackets refer to figure 2. 1 Switch on the sonar by pressing the ON- OFF/HOIST button (2) for approx. two seconds. The button lights green to indicate that the transducer is in the upper position.
Operation 5 MENU OPERATION The menu joystick can be moved in four directions: up, down, to the right and to the left. The up and down movements are used to move the cursor (inverted video) up or down to the desired position. Movement to the right is used as the ENTER function, and will hereafter be called ”press ENTER”. Movement to the left is also used as an ENTER function, and when the menu cursor is in the main menu or the extra menu, this ENTER function will bring up a catch data page (see chapters 5.
Simrad SD570 If the operator wishes to change one of the settings in the menu, the cursor must be moved up or down until it covers the desired function. Press ENTER, and the submenu for this control function will appear on the screen. The cursor will then be on the relevant setting. Move the cursor to the desired function and press ENTER to complete the operation. The submenu will disappear, and the new setting will now appear in the main menu.
Operation 5.1 Mode The sonar has nine different operational modes. To select the MODE submenu, move the menu cursor to MODE in the main menu and press ENTER. MODE: BOW UP NORTH UP TRUE MOTION 180°/AUDIO 180°/ECHOSOUND 180°/VERTICAL 270°/VERTICAL OMNI/VERTICAL OMNI/ECHOSOUND Use the menu joystick once more to select the desired operational mode. The selected mode will then be displayed. When pressing ENTER, the submenu disappears, and the cursor goes back to the main menu.
Simrad SD570 5.2 Pulse form With this function one may choose the form of the transmitter pulse: PULSE FORM.: CW SHORT CW NORMAL CW LONG *FM AUTO FM 1 FM 2 FM 4 FM 8 CW (Continuous wave): The frequency of the transmitter pulse is here constant. There is a choice between three pulse lengths: short, normal and long. In addition, the length of the pulse will change automatically in accordance with chosen range. The table below shows the different pulse lengths for CW and FM.
Operation There is a choice between five different modes: FM- AUTO: Chooses automatically the optimal number of frequencies (1- 8) for selected range. FM- 1: Transmits one- frequency pulses with a total pulse length of 0.6 ms FM- 2: Transmits two- frequency pulses with a total pulse length of 2.
Simrad SD570 5.3 Transmission power The transmitter operates with three different power settings in addition to OFF (passive). TX POWER...: *FULL MEDIUM LOW OFF The output voltage which can be checked on the voltmeter in the transceiver unit has the following values: FULL: MEDIUM: LOW: 90 V 40 V 20 V Note that the output voltage can drop as much as 30% during the transmission pulse.
Operation 5.4 Ping sector The ping sector is defined as the sector covered by one ping. The size of the sector can be selected between 360° (OMNI) and 11° (single beam). PING SECTOR: *OMNI 11° When choosing 11°, the current bearing will be the centre of the beam. Furthermore, the beam can be turned manually by means of the train buttons, or automatically in the AUTO SEARCH or tracking programmes.
Simrad SD570 5.5 TVG (Time Variable Gain) The TVG controls the gain in the signal amplifier. The gain is weakest just after the ping and increases in accordance with time (and therefore distance). The TVG reaches the maximum gain at 1000 meters. TVG........: OFF 10 LOG 15 LOG *20 LOG 25 LOG 30 LOG R R R R R In addition to OFF, the TVG can be selected with five different curve slopes, each having different gain regulation.
Operation 5.6 AGC (Automatic Gain Control) This control adjusts the gain in the sonar’s preamplifier dependent on the strength of the incoming echo signals. The result is a filter- effect reducing noise and reverberation. AGC........
Simrad SD570 5.7 RCG (Reverberation Controlled Gain) The RCG function is individual for each of the 32 receiving beams. Signals with small variations, like propeller noise, surface and bottom reverberation will be eliminated, while signals with fast variations, like target echoes or bottom echoes will not be removed. RCG........: OFF WEAK *MEDIUM STRONG As shown in the menu the RCG function has four different settings.
Operation 5.8 PP Filter The sonar is equipped with a ping- to- ping filter in order to reduce all unwanted noise and echoes from the screen. The filter has three different strengths: PP FILTER..: OFF WEAK *MEDIUM STRONG As the ping- to- ping filter compares the echoes from the last 2 (WEAK), 4 (MEDIUM) or 8 (STRONG) pings, it will take this selected amount of pings to make a stable presentation when changing most of the sonar functions.
Simrad SD570 5.9 Markers This menu shows position data (distance, bearing and depth) for the markers in the sonar picture. Positioning of markers is described in chapter 1.2.(3) “Display oriented push buttons”. MARKERS M DIST. BEAR DEPT 1 12345 -134 1234 2 564 89 120 3 1567 121 675 4 1234 143 566 5 876 113 98 6 832 -78 176 7 854 9 123 8 88 -173 46 C 455 131 76 A maximum of eight markers can be positioned at one time.
Operation 5.10 Audio sector The audio sector is the part of the ping which is reflected in the audio channel. The size of the sector can be selected from the menu: AUDIO SECT.: *11° 33° 55° 77° 99° When using AUTO SEARCH for audio search, the step of the search will be equal to the selected audio sector. Note that the audio sector can never be larger than the ping sector if a ping sector of 11° is used.
Simrad SD570 5.11 Tilt step When AUTO TILT has been selected, the tilt step function is used to decide by how many degrees the tilt angle is to be changed for each ping. TILT STEP..: 1° *2° 3° 4° 5° 6° 7° 8° 9° 10° The limits for the tilt searches are set by the tilt controls at the operator’s panel (see description of tilt control).
Operation 5.12 Track window This function is only used when target tracking is selected. TRACKWINDOW: SMALL *MEDIUM LARGE The selected target window is presented on the bearing line. As the sonar will follow the strongest echo inside this window, it is used to prevent the sonar from locking to surface or bottom echoes close to the desired echo. The window is automatically centred on the strongest part of the echo.
Simrad SD570 5.13 Colour threshold The strength of the echoes is presented by a scale of 32 colours on the screen. A weak echo has a cold colour (blue), medium echoes warmer colours (green, yellow) and strong echoes the warmest colours (orange, red). If desired, the number of colours may be reduced. In that case one starts with the colour representing the weakest echo. The number of colours that can be reduced depends on the selected menu colour.
Operation 5.14 Display gain Display gain increases or decreases the colour threshold on the screen. DISPL. GAIN: 0 1 2 3 4 *5 6 7 8 9 Display gain only controls the presentation on the screen, it is the gain control on the front panel which controls the receiver’s total gain.
Simrad SD570 5.15 Wind marker A wind marker can be selected in the menu for COSMETICS (see chapter 5.17). The marker which can be used to indicate the wind or current direction, has to be adjusted manually.

Maintenance 1 INTRODUCTION This section deals with maintenance work that may be carried out by the user. In addition to cleaning the cabinets and dust filters, the user should inspect the sonar room at least once a week. The ventilation and heating system, as well as the bilge pump arrangement should then be checked to be in good working order. The spare part box which is delivered with the sonar, contains fuses for the complete sonar.
Simrad SD570 2 SONAR CONTROL UNIT 2.1 Cleaning The cabinet should be kept clean and dry. Remove salt water residue with a soft cloth which has been moistened in fresh water. Do not use strong solvents. Note ! 2.2 The display screen should be handled with care to avoid damaging the anti- glare filter coating. Use a soft cloth without any strong solvents when cleaning it. Dust filter There is a dust filter on the air inlet at the rear wall of the Sonar Control Unit (refer to figure 1).
Maintenance 2.3 Replacing fuses The Sonar Control Unit is fused with two 3.15A slow blow fuses on the rear wall (refer to figure 1). Figure 1 - Location of fuses in the Sonar Control Unit Before changing fuses on the Sonar Control Unit, make sure that the mains power plug at the rear of the unit is correctly mounted. Spare fuses are located in the spare parts box.
Simrad SD570 3 3.1 TRANSCEIVER UNIT Dust filter There is a dust filter in the bottom of the Transceiver Unit. To avoid overheating, this should be inspected, and if necessary, cleaned once every third month. The dust filter is accessible from the outside of the Transceiver Unit, by unscrewing the eight finger nuts in the bottom of the unit. The filter should be vacuum cleaned, or washed in soap and water. If washed, the filter must be dried thoroughly before being reinstalled. 3.

Simrad SD570 4 4.1 HULL UNIT General The sonar hull unit should be under continuous watch as a part of the vessel’s machinery. As it may be exposed to severe strain because of pitching and vibrations, it should be inspected for loose parts. In addition to lubrication (see chapter 4.4), check for signs of corrosion. If required, clean the corroded areas and paint over with a high quality protective paint. 4.
Maintenance Figure 3 - The motor control unit 4.3 Cleaning the transducer The transducer normally needs little attention. However, the transducer face should be inspected and cleaned when docking. Do not use strong solvents, but a normal synthetic soap and water. Marine growth should be carefully removed with fine--grade sandpaper or emery paper. Note ! 850--160140 / A The transducer face must not be painted.
Simrad SD570 4.4 Lubrication of the Hull Unit From the factory, the Hull Unit is lubricated with the types of oil or grease as specified below. However, if of equal quality, other types may be utilized.
