SYSTEM DESCRIPTION
Introduction
The Simrad SH80 sonar is an omnidirectional high frequency sonar, designed for all sized fishing vessels, both purse seiners and trawlers. The standard frequency is 116 kHz (multiple frequencies as option), and the beam can be electronically tilted from +10 to -60 degrees.
Great emphasis has been placed on giving the best possible presentations on a high resolution colour display. The processor unit is controlled by Microsoft's Windows XP® operating system, which result in a flexible choice of display modes for a large range of user applications.
The signal processing and beamforming is performed in a fast digital signal processing system using the full dynamic range of the signals. In addition to the traditional single frequency transceiver system, the SH80 sonar contains an advanced frequency modulated filter system (FM).
The cylindrical multi-element transducer allows the omni-directional sonar beam to be tilted electronically down to -60 degrees. This allows you to automatically track schools of fish, and to observe the whole water volume around the vessel. A stabilization system is included for electronic pitch and roll compensation.
System overview
Main units
The Simrad SH80 sonar consists of the following units:
- Wheelhouse units:
- Display monitor
- Sonar Operating Panel
- Sonar Processor Unit
- Sonar Interface Unit
- Sonar room units:
- Transceiver Unit
- Hull Unit
Wheelhouse units
The Display Monitor is a high-resolution colour LCD (Liquid Crystal Display). In addition to the sonar picture, the monitor can also display the user menu for the interactive operation. In order to ease the situation comprehension, certain colours have been chosen to better the distinction between the various elements in the scene.
The Operating Panel contains all necessary control functions
Sonar room units
The Transceiver Unit is located in the sonar room, close to the Hull Unit. One signal cable is used for communication with the Sonar Interface Unit in the wheelhouse. The transceiver performs the signal processing and the digital beamforming of the 240 transmitters and 480 receiver channels, which are located on the eight identical transceiver boards.
The Hull Unit is designed to be lowered 1.0 meters below the ship's hull. The transducer can also be lowered to any selectable middle position. Note that in case of voltage failure, the Hull Unit can be manually raised or lowered by means of a hand crank.
The cylindrical 480-elements transducer allows the sonar beam to give full 360 degrees coverage of the water volume down to -60 degrees.
The sensor for the electronic stabilization of the sonar beams is housed in the Motor Control Unit, which is mounted on the Hull Unit.
Warning: If the transducer hits larger objects or bottom, the transducershaft maybe bent, or in worst case it can be broken off. A brokentransduce shaft will cause water leakage in the top of the shaft. Top prevent larger leakages in such a case, donot_ raisethetransducershaft to the upper position. Top prevent serious damagesitis

Options
General
The standard SH80 sonar is a single 116 kHz version with beam stabilization.
The beam stabilization was an optional function until 1 January 2003. After that date, the function was included with the standard sonar delivery.
The options described below are pre-programmed into the standard software version, and a code word is required to make the actual option available. Simrad offers a 1 month free test period for certain options. Note that the Scientific Output function is not available for such a test period.
For a permanent installation of a chosen option, a new code word will be released from Simrad when the option is ordered.
Multiple-frequency
In addition to the standard 116 kHz frequency, a multiple frequency option is available. In this multiple frequency version you can select between 13 frequencies from 110 to 122 kHz in 1 kHz steps.
Scientific output
The Scientific Output is designed for research purposes. When

Functional description
Introduction
The basic principles of the SH80 sonar are unique because of the 240 transmitter and 480 receiver channels with their transducer elements spread around on the cylindrical transducer array.
The transmission, reception and data processing are under computer control, and the powerful capabilities of the sonar are the results of sophisticated digital signal processing software and state of the art hardware.
Functional principles
When the Omni beam is tilted, the total beam picture can be compared with folding an umbrella, which means that all beams in 360 degrees around the vessel have the same tilt angle.

Stabilization system
When the beam stabilizer is activated, both horizontal and vertical beams will be stabilized electronically for roll and pitch movements up to ±20 degrees. The beam direction will then change continuously according to the vessel's movements, and secure an optimal contact with the targets even in rough seas.

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:
However, the sound absorption in salt water increases with the frequency, thus giving the lower frequencies along detection range.

Peripheral equipment
The SH80 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 peripheral equipment can be connected to the sonar.
- A (D)GPS may be connected to the SH80 sonar to establish the vessels position and provide cursor and marker latitude and longitude.
- Simrad echo sounders (EQ, ES and EK Series) provides a bottom plot on the catch data page.
- Simrad PI32 and PI44 Catch Monitoring systems provide the net depth in digits and bars on the catch data presentation.
• Simrad trawl instrumentation; FS 900, FS 3300 or ITI
- FS 900 and FS 3300: The trawl will be displayed in correct depth.
- ITI: The trawl will be displayed in correct size, depth, distance and bearing.
- A Current meter system will indicate the current speed and direction for up to three different depths in the sonar picture.
- A radio buoy system (GPS type) will provide the geographical position of the buoy(s) in the sonar picture.
For connection of any of this peripheral equipment, contact your local dealer.
DISPLAY MODES
Introduction
This chapter describes the SH80 display modes. The various modes represent the graphical presentation of sonar data. Several display modes are available to present the best possible presentations as well as flexible choices for a large range of user applications.

North Up
When the North Up mode is selected, true north is always up on the screen. The vessel symbol is stationary with the bow pointing in the vessle's course direction. The movement of the echoes across the screen are controlled by a combination of the vessel's course and speed and the target's own movements.

When the True Motion mode is selected, the picture is locked to a geographical position, where the vessel moves around the screen according to its present course and speed. All echoes are always presented in their correct position relative to the vessel, and their movements on the screen will be a true representation of the movements of the targets through the water.

Display modes
180°/Audio
When the 180°/Audio mode is selected, the upper half of the screen shows a 180 degrees bow-up presentation, while the lower part is used for a recording of the audio channel.

The audio channel is shown with a continuous white line in the
270°/ Vertical
The 270°/Vertical mode is specially designed for purse seining. The vertical half slice is displayed in the lower left corner for normal setting with the net on the starboard side. If the net is set on the port side, the 60 degrees vertical slice will be displayed in the lower right hand corner.

When the True Motion/Vertical mode is selected, the picture is divided into three sections; where the left side is a True motion presentation similar to the true motion presentation previously described.

Display modes
Dual 1
The Dual 1 mode is a kind of “two sonars in one” operation, where each presentation is updated for every second transmission. All settings can be set individually for each of the two presentations. This makes the dual mode especially useful for optimizing settings by directly comparing the two presentations.

Dual 2
The Dual 2 mode is very similar to the Dual 1 mode previously described, but the “two sonars” are presented next to each other. All settings can still be set individually for each of the two presentations.

Sonar Operating Panel
SONAR OPERATING PANEL
Introduction
You may enter operational commands directly on the Sonar Operating Panel. Sonar functions may also be accessed and activated using the menu field on the display and the trackball on the operating panel.
Frequently used functions are directly accessed by the designated control buttons. These are grouped according to their purpose.

SonarOperatingPanel
CD6377B

Main switch
Main switch functions control power to the sonar, hoisting and lowering of the transducer and indicates the transducer's current position.
Power
Pressing Power for approximately two seconds powers up the sonar. The adjacent green LED blinks while the Sonar Control Unit boots up, and remains illuminated once the system is operational.
Before the sonar can be powered down, the transducer must be in the Up position. Pressing the Power button for approximately two seconds secures power to the unit which is confirmed by the adjacent green LED being extinguished.
Up
Raises the transducer to its upper position. The adjacent green LED blinks while the transducer is raised and remains illuminated once it is housed safely inside the hull of the vessel. The green blinking LED will also be accompanied by an audible signal.
Middle
Raises or lowers the transducer to its middle position.
The physical location of the middle position can be defined in the Transducer parameter dialogue.
Symbol
The Symbol functions provide on-screen graphic references for targets, own ship and fishing gear.

(A) Target marker
To mark a target, move the cursor over it and press the button. A triangular symbol with a corresponding number will appear on the screen over the target.
Position data for the defined markers are displayed in the Objectsmenu.
Note that the system continues to track the markers even when outside the sonar range.
The Target marker function can also be used for manual target tracking as the system is designed to calculate the speed (S), course (C) and distance (D) between the last two chosen targets.
The Target marker data is displayed in white figures for three minutes in the lower right hand corner of the horizontal presentation. This function is also an effective method for determining the distance between two selected points on the screen.
(B) Own ship marker
Seine circle
This is a useful aid in planning the shooting of the purse seine. It is used as follows:
- Press the Gear button.
- The purse seine circle will appear on the forward end of the ship symbol on the corresponding side of the vessel selected in the Setup menu. The circle will follow the vessel's movements.
- At the moment the seine is shot, press the Gear button again.
- The purse seine circle will remain stationary and indicate the ideal path for setting the seine. Three square symbols on the ship's course line indicate the: shooting, one half, and the end of the seine positions. Three different nets can be pre-programmed in the Gearmenu.
- Press the Gear button to delete the Purse Seine circle.
Trawl symbol
This is a useful aid in providing an overview of the trawl operation.
Trawl data can be set manually using the menu or automatically by interfacing the Simrad FS trawl sonar or ITI trawl monitoring system with the sonar.
- In the manual mode the trawl symbol will be displayed with the selected size, depth and distance.
Mode
The four Mode buttons can be used to select either the four favourite display modes or user settings. The set up the buttons to choose modes or settings, select Mode Buttons in the Displaymenu.

About parameter dialogues and help
This chapter describes all the parameter dialogues accessed from the menu system.
When a parameter is selected, the available choices are shown in the dialogue below the menu. The setting is then made using the available buttons or lists. Several levels are frequently used to select the parameters.
Note that:
- In many cases you will not need to open the parameter dialogue, as you can control the settings directly on the menu button.
- The parameter is selected and activated by the sonar once it is highlighted in the dialogue. The operational changes can thus be investigated from within the dialogue without closing it.
- The Close button will always close the dialogue.
- The Help button will always provide short-form context sensitive help. This help text will appear on top of the parameter dialogue, and you need to press Close to return.
In the Help window, you can also press Free to access to full interactive manual. This may not be available in all

Parameters
Stabilizer
The Stabilizer button is located in the Setup menu.
Stabilizer: OFF
Stabilizer: ON
Whenthestabilizer isactive, the transducerbeam will bestabilized electronically for roll and pitch. The beam direction will change continuously according to the vessel's movements, and thus be compensated whenever the vessel is out of trim. The beam angle will always be maintained as if referred to a "flat" water surface. When the stabilizer is used, this will also allow you to use the PP Filterin rough seas. This filter will give a cleaner and more stable echo presentation.
The first example in the figure (top vessel A) indicates the sonar beam without stabilization, while the bottom vessel (B) indicates the stable sonar beam with the stabilization in operation.

ON-BOARD MAINTENANCE
Introduction
This section deals with maintenance work that may be carried out by the user. In addition to cleaning the cabinets and dust filters, you 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.
For location and replacing of fuses, refer to the chapter for the unit in question.
Major repairs and complete overhaul of the sonar must be left to an authorized Simrad service engineer.

Preventive maintenance schedule
Observe the following schedule for preventive maintenance on the SH80 sonar system. Use this information to create a preventive maintenance log, and make sure that every maintenance action is logged accurately.
Note: Its very important that the preventivemaintenance is carried out correctly as at the specified intervals. All guarantees is voided unless this schedule is followed.
Every three months
- Inspect the dust filters on the Sonar Processor Unit. Clean the filters, or replace if required.
- Inspect the dust filters on the Transceiver Unit. Clean the filters, or replace if required.
- Carry out all the necessary lubrication of the hull unit.
Every time the ship is in dock
- Perform a close visual inspection of the sonar trunk and the transducer.
- If required, clean the trunk and the transducer surface for marine growth.
Wheelhouse units
Cleaning
The units must be kept clean and dry. Remove salt water residue with a soft cloth moistened in fresh water. Do not use strong solvents.
Note: Thedisplayscreenmustbehandledwithcaretoavoiddamage totheanti-glarefiltercoating.Useasoftclothwithoutany strongsolventswhencleaningit.
Dust filter
To avoid overheating, the dust filter(s) must be inspected, and if necessary, cleaned once every third month.
Due to design changes, your sonar may be equipped with either of the following computers.
APC10 Sonar Processor Unit
The dust filter on the APC10 is located on the air inlet on the rear side of the Sonar Processor Unit.

MC70 Sonar Processor Unit
The two dust filters on the MC70 are located on the air inlets on the front side of the Sonar Processor Unit.
The dust filters on the MC70 Sonar Processor Unit

The filter is accessible by simply pulling off the filter grid. Each filter should be vacuum cleaned, or washed in soap and water. If washed, the filter must be dried thoroughly before being reinstalled.
Transceiver Unit
Dust filter
There is a dust filter in the bottom of the Transceiver Unit. To avoid overheating, this must 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.
Replacing fuses
The Transceiver Unit is fused with two 8A slow blow main fuses (F205 and F206) located on the front of the Power Control Unit.

Hull unit
General
The sonar hull unit must be under continuous watch as a part of the vessel's machinery. As the hull unit may be exposed to severe strain because of pitching and vibrations, it must be inspected regularly for loose parts.
In addition to lubrication, check for signs of corrosion. If required, clean the corroded areas and paint over with a high quality protective paint.

The location of S302 in the Motor Control Unit

On vessels which have been in dock, the Hull Unit must be thoroughly examined, and the hoist/lower functions must be checked out and observed while operating the Hoist/Lower Switch (S302 in the Motor Control Unit). The hoist/lower motor will automatically stop when the transducer shaft reaches the upper or lower limit switch.
Remember to set the hoisting/ lowering switch back to Remote for normal operation.
Cleaning the transducer
The transducer normally needs little attention. However, the transducer face should be inspected and cleaned whenever the vessel is in dock.
To lower the transducer when in dock, use the hoist/lower switch S302 in the Motor Control Unit (mounted on the gantry). Set the switch to STOP to position the transducer at any vertical location.
Do not use strong solvents, but a normal synthetic soap and water. Marine growth must be carefully removed with fine-grade sandpaper or emery paper.
Note: Thetransducersurfacemustnotbepainted.
Hoist motor overload protection
To prevent the hoist/lower motor from overload, an overload circuit breaker S301 is located in the Motor Control Unit. This may automatically be switched off during hoisting if the vessel's speed is too high, or if the transducer shaft has been bent.
To reset the motor overload switch, open the Motor Control Unit, locate the switch S301 and press the button marked 1.
ThelocationofS301in theMotorControlUnit

Emergency hoisting and lowering
In case of a failure or an emergency in the normal hoist/lower operation controlled from the Sonar Operating Panel, the transducer may be hoisted and lowered from the Sonar Room.
Local control switch S302
If the 3-phase voltage for the hoist/lower motor and the +24 Vdc stand-by voltage from the Transceiver Unit are available, the transducer can be hoisted or lowered by means of switch S302 in the Motor Control Unit. The motor will automatically stop when the transducer shaft reaches the upper or lower limit switch.
Remember to set the switch back to Remote position when finished.
Hoist/ lower contactors K301 and K302
If the 3-phase voltage for the hoist/lower motor is available, the transducer can be hoisted and lowered by operating the hoist (K301) and lower (K302) contactors in the Motor Control Unit by activating the small switch handle on the front of the contactor.
Warning: Theswitchesmustbereleasedbeforethe transducershaftreachesupperorlowerposition, asthisoperationoverridesthetwolimitswitches.
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 used. The following number refer to the lubrication points on the illustration to the left.

(1) The ball bearing on the top of the hoist/lower screw must be lubricated with normal ball bearing grease.
(2) The hoisting spindle should be lubricated with TonnaSlidewayOilsS68.
(3) Topping up the shaft sleeve through the grease nipple is only required if the shaft is dry of lubrication, or if water tends to force its way up along the shaft. The shaft sleeve is filled with Esso CazarK1.
