1 SYSTEM DESCRIPTION

1.1 IntroductionThe Simrad SP70 sonar is a long range omnidirectional sonar,designed for medium and large sized fishing vessels, both purseseiners and trawlers. The standard frequency is 26kHz (triple andmultiple frequency as option), and the beam can be electronicallytilted from +10° to –60° (or -90° optional).

Great emphasis has been placed on giving the best possiblepresentations on a high resolution colour display. The processorunit is controlled by Microsoft’s Windows 2000 operatingsystem, which result in a flexible choice of display modes for alarge range of user applications.

The signal processing and beamforming is performed in a fastdigital signal processing system, using the full dynamic range ofthe signals. In addition to the traditional single frequencytransceiver system, the SP70 sonar contains an advancedfrequency modulated filter system (FM).

The spherical multi- element transducer allows the sonar beam tobe trained and tilted electronically in any direction. This gives thepossibilities for automatic tracking a school of fish, and fordisplaying the whole water volume around and below the vessel.An optional stabilization system is available for electronicallypitch and roll compensation.

1.2 System overview

Main unitsThe Simrad SP70 sonar consists of the following units:

• Wheelhouse units:

- Display Monitor

- Operating Panel

- Processor Unit

- Loudspeaker

• Sonar room units:

- Transceiver Unit

- Hull Unit

→ See figure 1 for the SP70 system diagram.

The Display Monitor is normally a 18” or 20” high-resolutioncolour LCD (Liquid Crystal Display). In addition to the sonarpicture, the monitor can also display the user menu for theinteractive operation. In order to ease the situationcomprehension, certain colours have been chosen to better thedistinction between the various elements in the scene.

The Operating Panel contains all necessary control functions foroperating the sonar. The controls are arranged in function groups,which gives a clear and easy operation. Note that all sonaroperation also may be made from the roller ball, or from anoptional remote standard mouse.

The Processor unit contains a ruggedized computer withinterface for the auxiliary equipment (log, gyro, GPS, echosounder, trawl systems, purse seine systems etc.). The processorunit runs the Microsoft Windows 2000 operating system,modified by Simrad to suit the SP70 sonar requirements. AnEthernet link is used for the communication with the transceiverunit in the sonar room.

The Loudspeaker reproduces the audio of the echoes for theselected audio channel.

The Transceiver Unit is located in the sonar room, close to theHull Unit. An Ethernet link is used for communication with theprocessor unit in the wheelhouse. The transceiver performs thesignal processing and the digital beamforming of the 240transmitters and 240 receiver channels, which are located on eightequal transceiver boards.

The Hull Unit is designed to be lowered 1.2 meters below theship’s hull at a maximum ship’s speed of 15 knots, and it uses lessthan 25 seconds for raising and lowering the transducer. Thetransducer can also be lowered to a middle position, where onlyhalf of the transducer face is outside the sonar trunk. Note, thatin case of voltage failure, the Hull Unit can be manually raised orlowered by a hand crank.

The spherical 240 elements transducer allows the sonar beam tobe trained and tilted electronically in any direction. This givesunlimited possibilities for automatic tracking of schools of fishand for displaying the whole water volume around and below thevessel.

The optional sensor for the electronic stabilization of the sonarbeams is housed in the motor control unit which is mounted onthe Hull Unit.

WARNING ! If the transducer hits larger objects or bottom, the transducershaft may be bent, or in worst case it can be broken off. Abroken transducer shaft will cause water leakage in the top ofthe shaft. To prevent larger leakages in such a case, do not raisethe transducer shaft to the upper position. To prevent seriousdamages it is therefore of great importance to have a goodpump and warning system in the sonar room.

1.3 Options

GeneralThe standard SP70 sonar is a single 26kHz version with 60_tilt. With the limitation of 60_ tilt, the sonar is most usefulfor purse seiners searching for fish in the upper water layers.This because the standard version do not include the 90° and180° vertical slice presentations. All display modes aredescribed in section; “Modes of operation”.

Note that all options are pre-programmed into the standardversion, where a code word is used to make the actual optionoperable. Simrad offer a 1-month free test period for each option.

→ For entering the code words, refer to the section; “Optioninstallation”.

For a permanent option installation, a new code word will bereleased when ordering the actual option.

Optional 90_ tiltThe optional 90_ tilt version is specially powerful for trawlers, butis also very popular for purse seiners. This because in this versionall the 180° vertical modes available.

System description

5850--164186 A

In the 180_ /Vertical and Omni/Vertical modes, a trainable 180_vertical slice is presented.→ Refer to section; ”Modes of operation” on page 10.

Optional triple-- or multiple--frequencyIn addition to the standard 26kHz frequency, options areavailable for triple and multiple frequencies. In thetriple- frequency version, the operator can select between 24 kHz,26 kHz and 2 8kHz, and in the multiple- frequency version he canselect between 22 kHz, 23 kHz, 24 kHz, 25 kHz, 26 kHz, 27 kHz,28 kHz, 29 kHz and 30 kHz. These selections are specially usefulto suppress interference from other sonars.

Optional stabilization system

Figure 2 - Optional stabilisation system

When the optional beam stabilizer is activated, both horizontaland vertical beams will be stabilized electronically for roll andpitch movements up to ±20°. The beam direction will then changecontinuously according to the vessel’s movements, and secure anoptimal contact with the targets even in rough seas.

1.4 Functional description

IntroductionThe basic principles of the SP70 sonar are unique because of the240 separate transmitter and receiver channels with theirtransducer elements spread around on the spherical transducerarray. The transmission, reception and data processing are undercomputer control, and the powerful capabilities of the sonar areresults of sophisticated digital signal processing software andstate of the art hardware.

Simrad SP70

Functional principlesWhen the Omni beam is tilted, the total beam picture can becompared with folding an umbrella, which means that all beamsin 360_ around the vessel have the same tilt angle.

Figure 3 - Omni beam

In the standard version, the beam can be tilted from +10_ up, to-60_down. For the optional 90_ tilt version, the beam can be tiltedfrom +10_ up to -90_ down, where -90_ is formed by one singlebeam straight down like an echo sounder.

In addition to seeing the target from above, it is also possible tosee the target from the side, by using the vertical slicepresentation. In this case the beam covers a continuous verticalbeam from 0_ to -60_ in one transmission. For the optional 90_ tiltversion, a complete 180_ vertical slice can be presented.

This vertical slice, which is presented by the white audio line inthe horizontal picture, can be selected to any bearing by themanual training control.

The combination of the OMNI mode and the vertical slice, willgive an optimal visualizing of the catch situation.

In addition to the OMNI picture, the vertical slice is especiallyuseful for visualizing the vertical distribution of a school of fish.In that way, it is not necessary to go over the target to see thedistribution on the echo sounder, which often results in aspreading of the school.

System description

Figure 4 - Vertical slice

Figure 5 - OMNI / vertical combination

For the optional 90_ tilt version, the OMNI/vertical combinationis used in several display modes to give the best situationoverview for both purse seiners and trawlers. In thesepresentations the seine net and the trawl can be seen in relationto the vessel, the school of fish and the bottom.

When the optional stabilization system is installed in the sonar,the horizontal and vertical beams will be stabilized electronicallyfor roll and pitch up to approximately ±20_. The stabilization maybe switched ON and OFF in the menu.

ReceptionA great effort has been made to reduce unwanted noise to get aclean and stable echo presentation. To achieve this goal the sonarreceiver has the following filtering possibilities:FM CORRELATION FILTER

In addition to the traditional single frequency transmittingmethod, the SP70 sonar is equipped with an FM correlationmode.In FM mode each transmission pulse contains up to 8 differentfrequencies, and the receiver makes a spectrum analysis andcompares the received echoes with the transmitted frequencycode. This provides a filtering effect, which efficiently reducesinterference, noise and reverberation. In addition to giving a cleanand stable echo presentation, this will normally also increases thesonar’s detection rangeFREQUENCY SELECTION (OPTION)

The optional triple- frequency (24 kHz, 26 kHz and 28 kHz) andmulti- frequency (22 kHz, 23 kHz, 24 kHz, 25 kHz, 26 kHz, 27kHz, 28 kHz, 29 kHz and 30 kHz) selections can be used forsuppression of interference from other sonarsAGC (Automatic Gain Control)This control will automatically adjust the gain in thepreamplifiers, dependent on the strength of the incoming echosignals. The strength of the filtering can be selected in the menu:OFF, WEAK, MEDIUM and STRONG. Note that the AGC issensing the echo strength in five fixed directions, and use this asa basis for adjusting all the receiver beams.RCG (Reverberation Controlled Gain)

RCG is sensing the noise level (reverberation, propeller noise,etc.), adjusting the gain individually for each of the 64 receiverbeams to eliminate the noise on the display. The strength of thefiltering can be selected in the menu: OFF, WEAK, MEDIUM andSTRONG. In the STRONG position, the RCG will effectivelyreduce the bottom in shallow water, while variations on thebottom will be displayed.Note that scattered fish can be perceived as reverberation, sotherefore RCG should be used with care if scattered schools are tobe detected.PP FILTER

The sonar is equipped with a ping- to-ping filter which gives aclean and steady presentation by reducing the interference andnoise. This filter compares the echoes from a selected amount oftransmissions (pings), and an echo has to be present in theselected amount of pings in order to be presented on the display.The selection is made in the menu, with the followingpossibilities:

System description

9850--164186 A

• OFF - filter switched off

• WEAK - compares 2 pings

• MEDIUM - compares 4 pings

• STRONG- compares 8 pings

Note that in rough seas, when the beam easily can miss the targetin several pings, the PP filter should be used with care.

TVG (Time Variable Gain)

The TVG function controls the gain of the receiver so that a schoolwith a given size and density is presented with approximately thesame strength on the display, inside the regulated TVG range.This can also be seen as a filter, because it reduces the noise closeto the vessel.

The regulated strength of the TVG can be selected in the menu.

TransmissionThe transmitting is controlled by the signal processor in theTransceiver Unit, with parameters chosen by the operator. Thereare 240 separate transmitters in the unit distributed on 8transceiver circuit boards. Each transmitter is individuallyaddressed and controlled from the signal processor. Thecontrolled parameters include power output and beam angles foreach transducer element.

1.5 Auxiliary equipmentThe SP70 sonar requires connection to a speed log and a coursegyro. An inaccurate log or gyro input will cause inaccurateindication of the vessel and target movements.

In addition to log and gyro, the following auxiliary equipmentcan be connected to the sonar:

• A (D)GPS may be connected to the SP70 sonar to establish thevessels position and provide cursor and marker latitude andlongitude.

• Simrad echo sounder (EQ, ES and EK series). Gives depthreadout in the menu and a bottom plot on the catch data page.

• Simrad PI30 Purse Seine System. Gives the net depth in digitsand bars on the vertical views.

• Simrad Trawl Instrumentation: FS 900, FS 3300 or ITI.

- FS 900 and FS 3300: The trawl will be displayed in correctdepth.

- ITI: The trawl will be displayed in correct depth, distanceand bearing.

For connection of any of this auxiliary equipment, contact yourlocal dealer.

2 MODES OF OPERATION

2.1 GeneralThis chapter describes the SP70 modes. The various modesrepresent the graphical presentation of sonar data.

Several display modes is generated for giving the best possibleoverview presentation and a flexible choice for a large range ofuser applications.

The full list of display mode selection is made in the second linein the menu, where the four first display modes easily can beselected with the four Mode buttons on the operating panel.

The amount of different display modes, depends on if theoptional 90° tilt is installed:

• Standard 60° tilt version: 8 display modes

• Optional 90° tilt version: 12 display modes

In the following description, the display modes, which only isincluded in the optional 90° tilt version, will be marked with“option” in the heading text. Also note that in some displaymodes, the size of the vertical slice is reduces to 60° for thestandard version.

Refer to the following for detailed descriptions of the modes:

→ Bow Up, see page 12.

→ North Up, see page 13.

→ True Motion, see page 14.

→ 180 / Audio, see page 15.

→ 180 / Echosounder (Option), see page 16.

→ 180° / Vertical (Option), see page 17.

→ 270° / Vertical, see page 19.

→ Omni / Vertical (Option), see page 20.

→ Omni / Echosounder (Option), see page 21.

→ Bow Up / Vertical, see page 22.

→ True Motion / Vertical, see page 23.

→ Dual, see page 24.

Note that the order of the display modes in the followingchapters, are used only for simplifying the display modedescription. Normally the order of the display modes depends onthe selected gear (seine net, bottom trawl or pelagic trawl) Thisbecause different initial display modes are used for easy selectionwith the four modes buttons on the operating panel. The order ofthe display modes can easily be changed in the menu.

→ Refer to page 69 for changing the order of the display modes.

2.4 True Motion

Figure 8 - True motion

When the True Motion mode is selected, the picture is locked toa geographical position, where the vessel moves around thescreen according to its course and speed. All echoes are always incorrect position relative to the vessel, and their movements on thescreen will be true representation of the movements of the targetsthrough the water.

When the vessel symbol reaches the screen edge, it willautomatically be moved to the centre or position determined bythe Off Centre button. This position is reset to the screen centrewhenever the mode is changed.

When selecting Target Track, the target will automatically bemoved to the screen centre.

2.5 180° / Audio

Figure 9 - 180° / Audio

When the 180° / Audio mode is selected, the upper half of thescreen shows a 180° bow up presentation, while the lower part isused for a recording of the audio channel.

The audio channel is shown with a continuous white line in thehorizontal picture, and can be trained in any direction. Therecorded echoes are a direct replica of the echoes under the whiteaudio line.

As the audio channel is recorded over a period of time, this modeis especially useful for detection of weak echoes mixed withreverberation or noise.

The recording of the audio channel is always stored in thecomputer, even if another mode is selected. That means that thisrecording will always be presented when selecting the180°/audio mode.

Note that the vessel symbol can be moved to any position in thehorizontal view with the cursor and Off Centre button.

In addition to the normal tilt indicator, the tilt angle is also shownin the vertical slice by a continuous white line. In that way, it iseasy to select the optimal tilt angle on an echo in the vertical slice,to get the best drawing of the echo in the horizontal presentation.

Modes of operation

19850--164186 A

2.8 270° / Vertical

Figure 12 - 270° / Vertical

The 270° / Vertical mode is specially made for purse seining,where the vertical half slice is displayed in the lower left corner fornormal setting of the net on starboard side. If the net is selectedto be set on the port side, the vertical half slice will be displayedin the lower right-hand corner.

With this presentation mode, it will be easy to keep the bestcontact with a school in both the vertical and horizontalpresentation, and to determine the size distribution of the school.The position of the school relative to the bottom is anotherimportant information in the presentation.

The catch data page for purse seining is selected in the menu field.In addition to showing all the net data relative to the target andthe bottom, this page will also shows all available target data.

3 OPERATION

3.1 IntroductionAll operation of the sonar is normally made from the SonarOperating Panel. This section contains a detailed description ofthe start/stop procedures, the Operating Panel and the menuoperation. In order to get the necessary understanding of thesonar working principle, read first through the section “SystemDescription”.

In addition to the Sonar Operating Panel, it is possible to connecta standard USB mouse or roller-ball with three switches. In suchcase, all the sonar operation can be made via the menu system.

Note that the SP70 transducer in its lower position reaches 1,2meter below the vessel’s hull, and that the maximum specifiedspeed in that position is 15 knots.

To ensure the best possible reliability of the sonar, it is importantto follow the maintenance procedures described in section“Maintenance”.

WARNING ! Whenever docking the vessel, the switch S102 at therear of the Sonar Processor Unit should be switched toOFF position to prevent inadvertent use of the sonar.This, because the transducer canbedamaged if allowedtransmitting in air.

→ For location of the switch S102, refer to figure 19.

When docking, also refer to section “Maintenance”.

3.2 Procedures

Start procedure

Note ! Before starting up the sonar, check that the depth is sufficient, and thatthe vessel’s speed is within the maximum speed specified with thetransducer lowered.

1 Start up the display monitor by pressing thePOWERbuttonon the monitor.

2 Start up the sonar by pressing the POWER button on thesonar operating panel for approximately two seconds. Thegreen LED beside the button indicates that the sonar startloading up the programme, and after approximately oneand a half minutes the sonar picture will be displayed.

3 Press the Down button for lowering the transducer to thelower position. The green LED beside the button will startblinking, and an audible signal indicates the lowering of thetransducer. When lower position is reached, the LED willilluminates continuously, the audible signal stop, and theupper button in the Status menu shows: TransducerDOWN.

This completes the normal start up procedure.

In case of power failure, or if the switch S102 at the rear side of theSonar Processor Unit has been switched OFF, the sonar has to bestarted by pressing the start switch S103 behind the small frontdoor on the Sonar Processor Unit.

System input is provided by an ergonomiclly designed controlpanel. Sonar functions may be accessed and activated using themenu field and console mounted roller ball. Frequently usedfunctions are directly available through designated control panelbuttons which are grouped according to purpose.

A thorough understanding of system functions and controls isnecessary to optimize overall performance. Sonar conditionsvary, sometimes drastically, and it is not possible to identifysettings that will provide the best data at all times. Careful studyof this section and that concerning Modes of operation is highlyrecommended, preferably while exploring the sonar’s variousfunctions at the same time. System operation is a dynamic activityrequiring regular adjustments and fine tuning to achieve the bestpossible results under varying environmental conditions.

Main switchMain switch functions control power to the sonar, hoisting andlowering of the transducer and indicates the transducer’s currentposition.

POWER

Pressing POWER for approximately two seconds powers up thesonar. The adjacent green LED blinks while the Sonar control unitis booting and remains illuminated once the system is operational.

Before the sonar can be powered down, the transducer must be inthe UP position. Pressing the POWER button for approximatelytwo seconds secures power to the unit which is confirmed by theadjacent green LED being extinguished.

1 When the cursor is positioned on the left hand side themenu button, the arrow symbol will be changed to a minussign, indicating that the selected parameter can bedecreased by pressing the Select button.

2 When the cursor is positioned on the centre of the menubutton, the arrow symbol will be changed to a menusymbol, indicating that a submenu can be selected bypressing the Select button on the operating panel. Thesubmenu will then appear in the lower part f the menu field.This will give an overview of the selectable parametersettings for that actual menu button.

3 When the cursor is positioned on the right hand side themenu button, the arrow symbol will be changed to a plussign, indicating that the selected parameter can beincreased by pressing the Select button.

Selecting new parameter valueThe menu system is operated by the roller ball and the Selectbutton on the operating panel.

After experience, when the contents of the submenus are betterknown, the increase/decrease function on the actual menubutton can be used directly without selecting the submenu.

When the submenu for a menu button is selected, the parameterscan be changed in two different ways:


• Using the increase/decrease function on the menu button formoving the parameter pointer up or down in the submenu.The submenu can then be closed by pressing on the centre ofthe menu button.

• Moving the cursor on to the new parameter in the submenu,and press Select. The submenu can then be closed by pressingthe Close button in the submenu field.

The parameter value shown in the menu button is operable evenwithout closing the submenu. This simplifies the testing of thedifferent parameters effect. Note that the transceiver relatedparameters will first be in operation in the next ping.

The menu settings marked with an asterisk, indicates the normalsetting which perform well under normal conditions. If one gotlost in the menu settings, a Default Settings function will bring upthese normal settings.

The sonar is equipped with a battery memory, which remembersall selected menu settings, even if the sonar is switched off.

Note that some of the menu buttons (example Range, Gain, Tiltetc.) have a dual operation, and will normally be operated fromthe operating panel. In such case, the parameter value shown inthe menu button will change according to the panel operation.For some of these dual operated menu buttons, the submenucontains more selections than only the main parameter (refer tothe Tilt menu). The philosophy behind this dual operation is to beable to operate the complete sonar from a single mouse.

Menu description

93850--164186 A

There is a selection between three different pulse lengths: short,normal and long. In addition the pulse length will changeautomatically in accordance with the selected range. The tableshows the different pulse lengths for CW and FM. The pulselength in CW is given in milliseconds (ms).

FM (Frequency Modulation):

In the FM mode, the transmitter pulse is frequency modulated.This provides a stable echo presentation and greater ability ofdetection as noise and reverberation are reduced.

There is a selection between five different modes:

FM AUTO. - Chooses automatically the optional number offrequencies (1 – 8) for the selected range.

FM1 - Transmits one- frequency pulse with a total pulse length of1 ms.

FM2: - Transmits two- frequency pulses with a total pulse lengthof 4 ms.

FM4: - Transmits four- frequency pulses with a total pulse lengthof 16 ms.

FM8: - Transmits eight- frequency pulses with a total pulse lengthof 64 ms.

The selected number of frequencies are transmitted in one ping,and the receiver unit undertakes a spectrum analysis to comparethe received echoes with the transmitter’s frequency code. Thisprovides a filtering effect, where only “own echoes” aredisplayed, and noise and other echoes are reduced. The table onthe previous page shows the maximum FM mode for all ranges.The maximum FM mode will automatically be selected whenusing FM AUTO.

This function will only be operative if the optional stabilizer isconnected. The stabilizer may be switched ON and OFF in themenu.

When the stabilizer is switched ON, the transducer beam will bestabilized electronically for roll and pitch. The beam direction willchange continuously according to the vessel’s movements, andthus be compensated whenever the vessel is out of trim. Thebeam angle will always be maintained as if referred to a “flat”water surface. When the stabilizer is used, this also allows the useof the PP- filter in rough seas. This will give a cleaner and morestable echo presentation.

The first example in the figure indicates the sonar beam withoutstabilization and the second indicates the stable sonar beam withthe stabilization in operation.

5 MAINTENANCE

5.1 IntroductionThis section deals with maintenance work that may be carried outby the user. In addition to cleaning the cabinets and dust filters,the user should inspect the sonar room at least once a week. Theventilation and heating system, as well as the bilge pumparrangement should then be checked to be in good working order.The spare part box which is delivered with the sonar, containsfuses for the complete sonar. For location and replacing of these,refer to the chapter for the unit in question.Major repairs and complete overhaul of the sonar, should be leftto an authorized Simrad service engineer.

5.2 Wheelhouse units

CleaningThe units should be kept clean and dry. Remove salt water residuewith a soft cloth which has been moistened in fresh water. Do notuse strong solvents.

Note ! The display screen should be handled with care to avoid damaging theanti-glare filter coating. Use a soft cloth without any strong solventswhen cleaning it.

Dust filterThere is a dust filter on the air inlet at the rear side of the ProcessorUnit. To avoid overheating, this should be inspected, and ifnecessary, cleaned once every third month.

Figure 154 - Rear side of the Processor Unit

SIMRAD

5.3 Transceiver unit

Dust filterThere is a dust filter in the bottom of the Transceiver Unit. To avoidoverheating, this should be inspected, and if necessary, cleanedonce every third month.

The dust filter is accessible from the outside of the TransceiverUnit, by unscrewing the eight finger nuts in the bottom of the unit.The filter should be vacuum cleaned, or washed in soap andwater. If washed, the filter must be dried thoroughly before beingreinstalled.

Replacing fusesThe Transceiver Unit is fused with two 8A slow blow main fuses(F201 and F202) located on the front of the Power Supply. If oneof the fuses are blown, the lamp L201 should light and lamp L202should be extinguished. If L201 does not light, check the fuses ofthe ship’s main power system.

In addition, the High Voltage Unit is fused with two 8A slow blowfuses (F204 and F205). If one of the fuses is blown, the lamp L205should light and lamp L206 should be extinguished.

Spare fuses are located in the spare parts box.

5.4 Hull unit

GeneralThe sonar hull unit should be under continuous watch as a partof the vessel’s machinery. As it may be exposed to severe strainbecause of pitching and vibrations, it should be inspected forloose parts.In addition to lubrication, check for signs of corrosion. If required,clean the corroded areas and paint over with a high qualityprotective paint.

Docking the vesselWhen docking the vessel, great care must be taken not to damagethe sonar trunk and protecting blister.Whenever docking the vessel, the switch S102 at the rear of theSonar Control Unit must be switched OFF.→ Refer to figure 154

When docking the vessel, great care must be taken not to damagethe sonar trunk and protecting blister.On vessels which have been in dock, the Hull Unit should beexamined and the hoist/lower functions should be tried out andwatched while operating the hoisting/lowering switch (S302 inthe figure in the motor control unit on the Hull Unit). Thehoist/lower motor will automatically stop when the transducershaft reaches the upper or lower limit switch.

Figure 156 -The motorcontrol unit

Remember to set the hoisting/lowering switch back to REMOTEfor normal operation.

Maintenances

159850--164186 A

Cleaning the transducerThe transducer normally needs little attention. However, thetransducer 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-gradesandpaper or emery paper.

Note ! The transducer face must not be painted.

Lubrication of the Hull UnitFrom the factory, the Hull Unit is lubricated with the types of oilor grease as specified below. However, if of equal quality, othertypes may be utilized. The following refer to the lubricationpoints.

Figure 157 - The Hull Unit

1 The ball bearing on the top of the hoist/lower screw shouldbe lubricated with normal ball bearing grease.

Simrad SP70

160 850--164186 A

2 The hoisting spindle should be lubricated withMOLYBDENUM DISULPHIDE GREASE.

3 Topping up the shaft sleeve through the grease nipple isonly required if the shaft is dry of lubrication, or if watertends to force its way up along the shaft. Remember to openthe pressure let-down plug when topping up. The shaftsleeve is filled with ESSO CACAR K1 from the factory.

Hoisting and lowering with hand crankIn case of emergency or for service purposes, the transducer maybe hoisted and lowered by means of the hand crank.

Locate the hand crank and the brake release bolt in the motorcontrol unit. Fasten the hand crank to the motor shaft, mount thebrake release bolt, and press the bolt to release the brake whilehoisting or lowering with the hand crank.

Air bleedingTo avoid damage of the transducer by transmitting in air insidethe trunk, the air bleeding system must be checked after the shiphas been docked.

Close the air bleeding cock on top of the trunk flange anddismount the pipe. Open the air bleeding cock and check that thewater is passing freely through the cock. Also check that the pipeis open by blowing in one of the pipe terminations.

Remount the pipe to the air bleeding cock and turn the cock to theopen position.
