Simrad SH90 Manual operation of the hull unit In the event of improper operation, the powerful 3 kW electric motor may cause serious damage to the equipment and/or injury to personnel. Therefore, before you start the operation, read carefully through the relevant procedure(s). You will then familiarize yourself with the method . If something breaks down If you think that something has been damaged on the sonar, contact your local dealer for advice.
Simrad SH90 Main units The Simrad SH90 comprises the following units: Normally installed in the wheelhouse: • Display Unit • Operating Panel • Processor Unit • Operating Panel power supply Normally installed in the sonar room: • Transceiver Unit • Power Supply Unit • Hull Unit Wheelhouse units Display Unit The colour display is a high-resolution monitor. In addition to the sonar picture, the monitor will also display the menu system for the interactive operation.
Simrad SH90 The computer is based on a commercial design, but the software and hardware has been specified and assembled by Simrad to suit the SH90 requirements. The computer holds a DVD player for use with future software upgrades. Figure 2 Processor Unit The purpose of this computer is to allow you to control the sonar. The computer serves several functions. • It controls the overall operation of the sonar functions. • It provides the graphic presentation of the sonar modes and echoes.
Simrad SH90 Unit in the wheelhouse, and a second Ethernet cable is used to control the hull unit. The third Ethernet cable connects to the Power Supply Unit. The transducer cables from the hull unit are plugged into the side wall of the Transceiver Unit cabinet using a special plug. The Transceiver Unit is mounted on the bulkhead using powerful shock absorbers. The connectors for power and interface are located at the bottom of the cabinet.

Simrad SH90 Omni beam 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. Figure 4 Omni beam principle The beam can be tilted from +10 up to -60 degrees down. In addition to seeing the target from above, it is also possible to see the target from the side, by using the vertical slice presentation.
Simrad SH90 Figure 6 Omni/vertical combination 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. Stabilisation system The Simrad SH90 is provided with a stabilisation system.
Simrad SH90 Reception 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: • FM Correlation filter • AGC (Automatic Gain Control) • RCG (Reverberation Controlled Gain) • Ping-to-ping filter • TVG (Time Variable Gain) • Noise filter FM Correlation filter The FM (frequency modulation) is a sweep in frequencies.
Simrad SH90 selected amount of transmissions (pings), and an echo has to be present in the selected amount of pings in order to be presented on the display. Note that in rough seas, when the beam easily can miss the target in several pings, the PP Filter must be used with care.
Simrad SH90 Scientific output The Scientific Output is designed for research purposes. When activated, the following data are available on an Ethernet (LAN) output: • Beam data • Target data • Own ship data • Gear data The scientific output option may also include software for a Scientific Data Logger. Peripheral equipment The Simrad SH90 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.

Simrad SH90 DISPLAY MODES This chapter describes the Simrad SH90 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. Note The descriptive order of the display modes in this chapter has been chosen only to simplify the descriptions. In operational conditions, the order depends on the selected gear.
Display modes Alternative method 1 Locate the Mode button on the top of each menu. 2 Click the Mode button to choose operational mode. Click the left or right side of the Mode button to choose mode, or the middle of the button to open the parameter dialog.
Simrad SH90 Bow up When Bow up mode is selected, the vessel symbol is stationary on the screen with the bow pointing upwards. The echo presentation covers 360 degrees around the vessel, and all echoes are updated for every ping. The distance from the vessel symbol to the outer echo ring is equal to the selected range. 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.
Display modes Bow up/Audio When Bow up/Audio mode is selected, the upper half of the screen shows a 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 horizontal picture, and it can be trained in any direction. The recorded echoes are a direct replica of the echoes under the white audio line.
Simrad SH90 Bow up/Vertical When Bow up/Vertical mode is selected, the picture is divided into three sections; where the left side is a bow-up presentation similar to the Bow up presentation previously described. The upper part on the right hand side is a Catch data presentation, while the lower part is a Vertical slice presentation.
Display modes Bow up/Dual Vertical When Bow up/Dual vertical mode is selected, the upper part of the screen shows a curtailed bow-up presentation, while the lower part shows two vertical slice presentations. The bearing of the left vertical presentation is indicated by the white audio line in the horizontal presentation, while the bearing of the right vertical presentation is indicated by the yellow-dashed line. All borders between the different views may be moved to any position by using the trackball.
Simrad SH90 Bow up/180° Vertical When the Bow up/180° Vertical mode is selected, the upper part of the screen shows a curtailed Bow up presentation, while the lower part shows a 180 degrees Vertical slice presentation. This mode is mainly intended for trawlers, where the vertical view acts as a multibeam echo sounder. The bearing of the vertical slice can be selected in the Vertical View menu.
Display modes True motion When 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.
Simrad SH90 True motion/Vertical When 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. The upper part on the right hand side is a Catch data presentation, while the lower part is a Vertical slice presentation.
Display modes North up When North up mode is selected, true north is always up on the screen. The vessel symbol is stationary with the bow pointing in the vessel’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.
Simrad SH90 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. To optimize the horizontal settings, use the Horizontal menu to try different settings in the upper picture. These settings are automatically transferred to the other modes.
Display modes 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.
Simrad SH90 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. With this presentation, it is easy to keep the best contact with a school in both the vertical and horizontal presentation, and to determine its size distribution.
Operating Panel OPERATING PANEL This chapter describes the Simrad SH90 Operating Panel. The frequently used functions are directly accessible by the designated control buttons on the Operating Panel, and may enter operational commands directly.

Simrad SH90 BASIC THEORY This chapter explains some of the basic theory related to settings, error sources and noise conditions. Topics • Settings on page 178 • Noise and reverberation on page 182 • Layers and deflections on page 185 Settings A sonar will transmit a sound wave into the water around the vessel. When this sound wave hits fish, bottom, or other objects in the water, a part of the sound will be returned as echoes.
Basic theory When you choose the TVG setting you can either switch it off, or choose a “X log R” value. The different settings determine how much gain the sonar will use as time elapses along the X-axis. A higher value for “X” will make the angle (C) steeper. What is AGC? AGC means Automatic Gain Control. The AGC will automatically scale the received echo data to maintain a proper dynamic range based on all the incoming echo values.
Simrad SH90 About beam widths A narrow beam will always reach further than a wide beam. This is because the transmitted power of the sonar is concentrated. Nevertheless, you can easily “miss” a school of fish if you make the beam too narrow. If the range is reduced, it is the common to use a wider beam. Figure 40 Beam widths A Large B Normal C Narrow The normal setting on the SH90 sonar is Normal. This setting is basically designed for longer ranges. You may also try setting Auto.
Basic theory On this sonar, you can adjust the horizontal and vertical gain independent of each other. The horizontal gain is used when the sonar operates in a horizontal mode, for example Bow up or True motion. If you switch to a mode with a vertical view, for example True motion/Vertical, your sonar will need a different gain setting for the beams directed towards the bottom. To adjust the gain, see How to adjust the gain on page 41. What is RCG? RCG means Reverberation Controlled Gain.
Simrad SH90 be easier to see when the RCG removes the bottom echoes. However, this assumes that the fish echoes are considerably stronger than the bottom echoes. If you use a very small tilt (C) you will not be bothered by bottom echoes. If the sea surface is gusty, you will however easily see echoes from the waves. These echoes will normally be rather weak, and will hardly move in relation to your vessel.
Basic theory Figure 42 Cavitation [1] When the bubbles collapse, they cause very strong local shock-waves in the water. These may be audible and can also damage the propeller blades. In addition to this, the cavitation will generate very strong reverberation, commonly seen as a red stripe of echoes behind the vessel. If you have big problems with cavitation, try to adjust the propeller pitch and/or the number of revolutions.
Simrad SH90 The echoes from the bottom will vary with how uneven the bottom is, what kind of bottom you have under your vessel, (rock, mud, sand etc.) as well as your current tilt setting. The echo from the sea surface will vary with the current sea state and your current tilt setting. The illustration demonstrates how the bottom and the sea surface return echoes back to your sonar transducer.
Basic theory How to check for electrical noise This procedure provides a simple method to check the electrical noise. 1 Switch off all electric equipment that can cause electrical noise. This includes motor, propellers, thrusters, winches, coolingand air conditioning systems, pumps, cranes, hydraulic systems etc. 2 Switch the equipment on again one at the time, and check the sonar every time. With luck, you will spot which of your electrical systems that create the noise.
Simrad SH90 Deflections On warm days – especially during summer – the sea surface will be heated by the sun, and the water temperature will gradually decrease with increasing depth. Figure 45 Water temperatures on warm days B A (CD015005G) When the temperature decreases (A) closer to the bottom, the sonar beam is deflected down as indicated by the illustration. The school of fish (B) you thought you would see is not visible at all.
