PART A: INTRODUCTION

Scanning sonar has many applications in commercial fishing, pleasure boating, sport fishing, navigation, diving and salvage, underwater security, and a host of other uses only now being developed. The HD800 series is designed for easy operation, and you will be able to learn how to use your sonar quickly.

PART B: YOUR NEW SONAR

WESMAR’s new HD800 series sonars have the most advanced technology of any marine electronic equip-ment on the market today, technology specifically designed to help you make more money.

With a newly designed screen display, special features, and four options menus, the HD800 sonars provide more information about the targets you’re after so you can make the kind of catches you want—profitable ones. The high-definition sonar screen offers four times the picture resolution of older models, which means you get a truly accurate presentation of what is in the water before and around you.

New features boost the effectiveness of the HD800 series and make your job easier. Front panel gain controls are digitally displayed on the screen for easy reference. Scanning speed can be increased or decreased instantly from the front panel enabling you to track fast moving fish. Adjustable thresholds and pulsewidth give added bottom discrimination. The four options menus were designed for the setup of your new sonar. After installation, on your first time out with the HD800, you can make many small

Section IISONAR OPERATION

WESMAR is famous for designing sonars that are easy to operate. The HD800 Series follows this tradition by having a minimum of controls. In addition, the HD800 series is the world's most advanced sonar. The technician or operator can customize the sonar to suit water conditions and fi shery by selecting different sonar parameters in menu.

WESMAR

HD800

PART A: OPERATION

Like all sophisticated computer equipment, the HD800 series sonar has temperature limits of 0 degrees C (32 degrees F) to 43 degrees C (110 degrees F).

THE SONAR SHOULD BE OPERATED ONLY WITHIN THESE TEMPERATURE LIMITS.

The HD800 has an internal memory that will remember all the special settings you have selected for your fish-ery. This internal memory will retain all your settings even when the sonar is turned off. There is a remote possibility the settings may return to the default set-tings if there is a power surge. If this happens, turn the sonar off, wait a few seconds, and turn it back on. Reset your special settings as before.

The HD800 sonar is like having two sonars in one; one part scanning horizontally, the other scanning vertically. With two separate operations, each has its own individual controls. When scanning horizontally, the adjustments are set for sonar operation. When scanning vertically, the adjustments resemble that of a sounder. When the sonar moves back and forth between the two operations, all preset adjustments also switch back and forth.

WESMAR


PART B: CONSOLE CONTROLS

The HD800 is a multi-option sonar designed for easy operation and interpretation. Following are some simple instructions and guidelines to help tailor the HD800 to your fishing or navigational needs.

1.0 POWER

To turn on your sonar, push the POWER Button. When power is applied the following will occur:

1.1 The monitor will show the system test screen for 10-20 seconds.

1.2 The Hoist Down light will turn red if the hoist switch is in the down position.

1.3 The cooling fan, located on the console back panel, will start to spin.

1.4 The console front panel lights will illuminate, vis-ible under low light conditions.

During this period the sonar performs a system test. When all the functions are operational, the screen will display:

SYSTEM TEST PASS

If other messages are displayed, consult your dealer or WESMAR.

In addition to system test, the version of the software is also displayed.

2.0 HOIST

The HOIST Switch raises and lowers the soundome. If the HOIST Switch is in the down position, the soundome will lower when the console is turned on and raise when the console is turned off.

WESMAR

HD800

When the sonar is on, the soundome can be retracted by moving the HOIST Switch to the up position. This is useful when operating the sonar in the sounder mode without extending the soundome.

2.1 Hoist Down LightWhen the Hoist Down Light is on, it indicates that the soundome is in the down position. This light serves as a warning. The light must go off when the soundome in retracted.

3.0 VOLUME

This control is used to raise and lower the volume of the external speaker. Sound is proportional to the echo strength of the target displayed on the screen. Also, weak targets below the preset threshold can be heard when volume is turned up.

4.0 BRIGHTNESS

The BRIGHTNESS Control allows you to adjust the intensity of the sonar display. For nighttime view, WESMAR recommends dimming all the white text and removing the blue background color. See Menu #3, this page. Note: If brightness knob is turned completely CCW, the video will still come on during self test, but then fade to a black screen. Simply turn the brightness knob CW to the desired brightness.

5.0 SONAR "A" GAIN/RANGE ADJUSTMENTS

5.1 Near Gain (Sonar)Rotating this multi-turn control clockwise will increase sensitivity of the sonar for the fi rst half of the displayed range. Near Gain values 0-100 are displayed left of the screen in the box titled NEAR.

Note: There are two sets of numbers in the NEAR box. Numbers to the right correspond to the sonar Near Gain control located on the right side of the front panel.

5.2 Far Gain (Sonar)Rotating this multi-turn control clockwise will increase sensitivity of the sonar for the last half of the displayed range. Far Gain values 0-100 are displayed to the left of the screen in the box titled FAR.

The numbers to the left correspond to the profi le Near Gain Control, located on the left side of the front panel.

6.2 Far Gain (Profi le)Rotating this multi-turn control clockwise will increase sensitivity of the profi le sonar for the last half of the profi le range. Far Gain values 0-100 are displayed to the left of the screen in the box titled FAR.

Note: There are two sets of numbers in the FAR box. The numbers to the left correspond to the Profi le Far Gain control located on the left side of the front panel.

6.3 Range (Profi le)The RANGE Control selects the vertical scanning dis-tance of the profi le soundbeam. There are 10 available ranges. The RANGE selected is displayed on the profi le screen to the left of the bottom range line.

WESMAR

HD800

7.0 TILT

7.1 Tilt, SonarThe TILT angle of the sonar soundbeam can only be changed when the soundbeam is scanning in sonar, full or split screen. When the soundbeam is in the sonar mode, the TILT switch will move the transducer from 4 degrees above horizontal to -90 degrees vertical. TILT angle is displayed in the TILT Box located on the left of the screen.

Note: TILT reading will go blank when scanning the bottom, in profi le, and taking a vertical scan (thickness) in sonar.

7.2 Tilt, Profi leThe TILT Switch has a second function. When the sound-beam is in the profi le mode, the TILT Switch selects the size of the Profi le Sector. By pushing down on the TILT Switch, the profi le sector will reduce approximately 10 degrees for each toggle. Pushing up on the TILT Switch increases the profi le sector.

8.0 BEARING

8.1 When operating in full screen sonar, 360 degree scan, the BEARING Knob will position a BEARING line around the screen. Relative BEARING to a target can be determined by positioning the BEARING line over the target. Relative BEARING is displayed in the SCAN box to the left of the screen.

8.2 When scanning a sector in sonar, the BEARING Knob will move the sector clockwise or counterclock-wise around the screen. The BEARING line marks the center of the sector.

8.3 When vertically scanning a school of fi sh for a thickness view, the BEARING Knob will reposition the vertical scan. Move the BEARING line over the target to view the thickness. The leading edge, center and tailing edge of a school can be profi led to validate density.

WESMAR


9.0 CURSOR

The CURSOR POSITION Switch moves the square shaped CURSOR up, down, left and right.

Horizontal range and depth of a target can be determined by placing the cursor over the target. Range and depth are displayed to the center right of the screen.

10.0 SECTOR

10.1 SECTOR Knob The SECTOR Knob lets you choose the size of the area to be scanned in the sonar mode. Sonar SECTOR is centered on the bearing line. Moving the bear line will move the SECTOR.

10.2 Manual Position Manual position will stop the soundbeam from scan-ning. This stationary beam can be positioned with the BEARING Knob and in tilt with the TILT Switch.

10.3 Full Screen Bottom Profi le or Full Screen Sounder, Selected in Menu 1.

10.3.1 BOTTOM PROFILE will scan the soundbeam across the bottom. Fish close to the bottom, contours and sea bed composition, will be displayed across the screen. By using the Tilt Switch, the PROFILE can be sectored down or up in 10 degree increments.

10.3.2 SOUNDER will tilt the transducer auto-matically down to 90 degrees and rotate in bearing to 90 degrees. At this position the soundbeam is stabilized for vessel roll providing excellent fi sh detection off the bottom. 10.3.3 SOUNDER-SIDESCAN When operating in the SOUNDER mode, both Tilt Switch and Bearing Knob will reposition the soundbeam in any degree of bearing and tilt.

For example: If you want to SIDESCAN the shore

WESMAR

HD800

to port, position the soundbeam to 270 degrees bearing with the Bearing Knob and tilt with the Tilt Switch. As the vessel parallels the shore, all targets between the vessel and shore will mark on the SOUNDER DISPLAY.

11.0 TRACK - VERTICAL PROFILE SWITCH

11.1 TRACK To TRACK a school of fi sh, the HD800 console must be connected to a GPS unit with NMEA 0183 output. The sentence format recognized by the HD800 is RMC and GLL, VTG. This format includes; time, latitude, longitude, speed over ground, course over ground and date. All this information is used to track and log each track into menu 4.

NOTE: There are many GPS models on the market rang-ing in speed and reliability. All GPS units give latitude, longitude, and calculate heading. Heading is calculated between two or more GPS updates. Because bearing is a calculation, the greater the distance between GPS readings, the more accurate your heading will become. WESMAR recommends a vessel speed of four knots or greater, with no course change during the target marking phase. Once tracking is engaged, the vessel may then pursue any course.

To TRACK fi sh detected in the sonar mode, place the cursor over the fi sh with the Cursor Position Switch. Immediately lift up the TRACK SWITCH. When the TRACK SWITCH is clicked up for the fi rst time, the HD800 console will calculate the GPS location of the fi sh, which it holds in memory. When the GPS location is calculated, the fi shlupe to the right of the screen will disappear.

Continue to sweep the target. When noticeable move-ment of the school is detected, mark the target for the second time with the cursor. Immediately lift up the TRACK SWITCH. Tracking is engaged when the fi sh

<

WESMAR


icons start to move to the right of the screen. Informa-tion as to: range to the fi sh and bearing to the fi sh from the vessel will be displayed in the fi sh box to the right of the screen. Also, speed and direction of the fi sh is displayed in the lower half of the fi sh box.

When tracking is engaged, range and bearing will dis-play on a green background for 10 minutes. After 10 minutes the background will change to yellow, also for 10 minutes. After 10 minutes of yellow, the background will change to red. When twenty minutes have passed, tracking will stop. Caution: The computer cannot ac-commodate the uncertainty of fi sh travel or affects of water currents.

This color change over time is to alert the operator that the expected path or calculated path of the fi sh may vary, due to change in direction or speed of the fi sh.

Each track is entered into a log located in Menu 4. Date, time, latitude, and longitude are entered at the top of the log. When the log is full the last entry at the bottom will disappear. To discontinue a track sequence, lift up the track switch for the third time. All track information will disappear and the fi shlupe will return.

11.2 VERTICAL PROFILE (THICK-NESS)As the soundbeam in sonar passes through a school of fi sh, push down on the TRACK SWITCH. An overlay screen equal to a fourth of the screen will show a vertical profi le or thickness of the school of fi sh.

When vertically scanning, the BEARING KNOB will reposition the vertical scan. By moving the bearing line over the target, the vertical profi le view will show the thickness of the leading edge, center and trailing edge of the school of fi sh.

VERTICAL PROFILE starts at 0 degree tilt and steps the transducer in 1.8 degree increments in the vertical plane down to -90 degrees. To sector the profi le for fast target update, press up on the TILT SWITCH. The sec-tor will move up from the vertical in 10 degree steps.

For quick scan reverse, set Function Switch to Position 6. Pressing down on the SELECT SWITCH will im-

<

WESMAR

HD800

mediately change direction of the Vertical Profi le Scan.

12.0 FUNCTION KNOB AND SELECT SWITCH

The FUNCTION KNOB includes fi ve separate on-screen listings of programming selections, plus QUICK SCAN REVERSE. Selection is made with the SELECT SWITCH while the sonar is running. The six functions follow:

12.1 SPEEDFunction 1- SPEED BOX highlighted, left of screen.

By pressing up or down on the SELECT SWITCH, you can select one of twelve scanning speeds for sonar and one of three speeds for bottom profi le. Each mode can have its own scanning speed.

Example: In SPLIT SCREEN the sonar can be set to Speed Six for fast long range search. Select Speed One in bottom profi le for high bottom resolution. When changing speed, the soundbeam must be in the Sonar Screen to make changes for sonar. The soundbeam must be in the Profi le Screen to make changes for Profi le.

VERTICAL PROFILE (THICKNESS) MODE al-ways scans at Speed One, High Resolution.

Note: In the sonar mode the Scan Speed numbers will turn red when the soundbeam from consecutive transmits no longer overlap.

Example: For the 160 kHz soundome, a scanning speed of 4 will give 100% horizontal coverage. At Speed Five the soundbeam will move between transmits greater than the soundbeam will cover, leaving part of the water column undetected.

12.2 POWERFunction 2- POWER BOX highlighted, left of screen.

profi ling the bottom.

WESMAR


By pressing up or down on the SELECT SWITCH, the operator can choose 100, 75, 50, or 25 percent of maxi-mum transmit power. This function is very helpful for adjusting the sonar to different fi sheries and conditions. A high transmit power provides the longest scanning range possible. A low transmit power output is use-ful at short ranges and/or in shallow water, because it minimizes refl ections that clutter the screen display.

Power can be selected separately for sonar and bottom profi le. Select POWER for the mode the soundbeam is in. The console will place both selections in memory. As the soundbeam goes from sonar to profi le, POWER will refl ect your change, magic.

12.3 PULSEFunction 3- PULSE BOX highlighted, left of screen.

Press up or down on the SELECT SWITCH to choose BOOST-100%, 50%, 25%, 12%, 6%, 3%, or 0% of the pre-programmed pulselength.

At the beginning of each new sweep, the transmitter transmits over a very brief period of time. That period of time is called the PULSE LENGTH, and is measured in milliseconds (1/1000). In actual practice, the short pulselength gives better resolution, bottom defi nition, and less noise in shallow water or surface scanning. A longer pulselength provides greater range.

The computer inside the sonar automatically changes the transmit pulselength, lengthening it to match longer ranges, and shortening it for shorter ranges.

Pulselength at 100% is normal sonar setting. However, you can select BOOST for an extra long pulselength to extend your range capabilities beyond other sonars.

WESMAR

HD800

Depending on need and application, a shorter pulselength will give better target defi nition off the bottom, shore, and working close to the surface.

When 0 pulselength is selected, the transmitter is turned off. The sonar then operates in a passive mode, listening only. Sonar targets will not exist. Zero pulselength is excellent for troubleshooting vessel vibration, propeller, engine and electrical noise.

Pulse can be selected separately for sonar and bottom profi le.

Example: Set pulselength as short as possible for bottom profi le to spot fi sh closest to the bottom. Set pulselength longer for sonar when scanning long range.

12.4 TVG (TIME VARIABLE GAIN)Function 4- TVG BOX highlighted, left of screen.(TVG can be selected separately for sonar and bottom profi le.)

Press up or down on the SELECT SWITCH to select 100 through 2000.

Normal TVG settings:

FREQUENCY MILLISECONDS 180 kHz 300 160 kHz 400 110 kHz 600 60 kHz 800 45 kHz 1000 27 kHz 1200

TVG (Time Variable Gain) offsets the effects of propa-gation loss of sound as it passes through the water. Propagation Loss of sound is the sum of Spreading and Attenuation Losses. Spreading Loss refers to the physical spreading of sound energy as it travels outward from the source and back from the target. Attenuation Losses are primarily due to absorption and the scattering of sound as it passes through the water.

Spreading Loss is a constant where the sound energy decreases as the square of the range. The type of loss is also called inverse-square or spherical spreading losses.

To counter this loss, the TVG curve is adjusted by the Near Gain and Far Gain control on the front panel.

Near Gain controls the complete gain curve and has its greatest affect on targets displayed in the fi rst half of the sonar range. Far Gain controls the height of the gain curve and has its greatest affect on targets displayed in the last half of the sonar range.

When both Near and Far Gains are adjusted correctly, targets at long range will not change in density as the vessel approaches. Also, target density will remain con-stant from one range to another. Gain controls can be adjusted for all conditions the operator will encounter, ensuring accurate target presentation.

Attenuation Losses are more dramatic in equatorial waters than in northern and southern waters. Because of this, wide variations in the TVG slope can be calibrated for your region. TVG calibration allows the operator to adjust the end of the TVG slope in range. When cor-rectly set, all operational adjustments are then made with the Near and Far Gain controls on the front panel.

The range where the TVG slope ends can be viewed on the screen marked as a light gray ring. The TVG RING will move in and out when selecting TVG numbers, TVG number of 400 equals to 300 meters or 1000 feet.

This band of warmer water can vary in depth. Typically, depths from 10 to 100 meters can be warmed by the sun. Below this band of warm water, the temperature could drop to a few degrees above freezing. It is at this point, where the near surface water layer meets the deeper cold waters, where the fi sh are likely to be located. When the temperature changes rapidly with depth (thermocline), it plays an important role as the food chain tends to be located in this area.

In search of thermoclines, WESMAR designed a new reusable temperature probe, or RTP, that is retrievable. The probe can be lowered down to 50 fathoms monitor-ing temperature along the way. The RTP can be reused as often as you wish in search of thermoclines.

PART A: CONSOLE AND MONI-TOR INSTALLATION

1.0 LOCATION

1.1 The Slimline console may be installed in any con-venient place inside the vessel--on a fl at surface or set into overhead or bulkhead mounting. Make sure the console is not close to any inverters, converters, or transformers than man interfere with the sonar performance.

Install console and monitor in a location away from salt spray, heat sources and direct sunlight. Allow airfl ow to the console cooling fan, located on the back panel. Never install a display monitor on top of a Slimline console. A monitor on top of the console may introduce noise and lower sensitivity.

In general, the HD800, like all other sophisticated computer equipment, must be protected from severe temperature conditions.

2.0 ACCEPTABLE POWER SOURCES

All HD800 consoles operate on a universal power supply of 12 to 32VDC voltage.

The Slimline console has an AGC 32V (fast blow) fuse, which varies according to input voltage:

FUSE 12v 7.5 AMP AGC 24V 3.2 AMP AGC 32V 3.2 AMP AGC

NOTE: Before connecting the console to ship’s power, check fuse to see if it has the correct AMPerage.

A power surge or lapse may cause your sonar to freeze. If this happens, turn the sonar off and on.

Using a power source that maintains its voltage and has a minimum of voltage surges and spikes will ensure

Allow 25 mm (1 inch) clearance on the sides of the console for adequate airfl ow.

good performance and long life for your WESMAR sonar.

3.0 CONNECTING POWER TO THE CONSOLE

HD800 consoles come with a 3.0 meter (10 foot) long power cable.

At one end of the cable, connect the white wire to negative [ — ], and the black wire to positive [ + ] on the ship’s power cable.

Be sure the ship’s cable is large enough to send the needed amount of current through the WES-MAR power cable to the sonar equipment. Use the chart below for reference.

is designed to operate a Computer Monitor. This type of monitor provides excellent color in great detail. Definition is superb, with more pixel information than other sonars.

MONITOR SPECIFICATIONS:

Horizontal Sync: 31.5 kHz Vertical Sync: 60 HZ

NOTE: Some monitors are auto sync. The auto sync frequency of the monitor must fall within the above frequencies. A 0.28mm dot pitch is recommended.

Computer monitors come with their own video cable with a 15 pin "D" connector. If your moni-tor was not supplied by WESMAR, be careful in determining the correct wiring. Monitors supplied by WESMAR will have the correct connector prewired.

5.0 DISPLAY MONITOR VOLTAGE

If your vessel does not have the correct voltage to operate the computer monitor, an inverter or converter is required. For example, if your monitor requires 115VAC, and your vessel has 24VDC, use a 24VDC to 115VAC inverter. Converters and inverters are available from WESMAR.

Do not mount the inverter or converter directly next to the console or display monitor.

This will introduce ripple on the monitor screen. Also, the inverter or converter must be mounted in a location where air circulation is adequate.

Route the interconnect cable from the console to the hoist assembly.

Follow these precautions:

~ Do not run the cable near heat sources or electric motors, inverters, converters or transformers

~ Route the cable through conduit in areas where it may be damaged

~ Do not bend the interconnect cable into a radius less than 10cm (4 inches)

NOTE: Wrap the interconnect cable terminal lugs in paper and tape to protect them from dam-age when stringing the cable through cable runs.

Route the interconnect cable through the right large strain relief in the bottom of the Junction Box.

Connect the numbered lugs of the interconnect cable to the same numbered terminals on the Hoist and Transmit/Receive Boards.

Plug the interconnect cable connector into the matching connector on the back panel of the console.

NOTE: The connector is keyed and will align only one way. If you wish to change the align-ment for easier connection, follow the steps in steps in 6.1.

6.1 Repositioning the Connector Shell

If necessary, reposition the connector shell by fol-lowing these steps:

6.1.1 Remove the two cable clamp screws and un-screw the clamp flange.

6.1.2 Remove the two locking screws, or unscrew the locking ring from the cable connector shell assembly.

6.1.3 Remove the two halves of the shell assembly from around the cable.

6.1.4 On the inside of each half of the shell is a small key. This key aligns with one of the

Special Note:If you have a Model 18 Long Stroke Hoist, you will have to route the cable for the Hoist Travel Selection Box when you route the interconnect cable.

8 notches on the back of the wired connector.

Position the connector so that the keyway points toward the top of the console when installed.

6.1.5 Place one half of the outer shell in the desired cable run direction, and align the key with the appropriate notch.

6.1.6 Install the other half of the outer shell and clamp the halves together by inserting the two locking screws, or by screwing on the lock-ing ring. Make sure that no wires are pinched between the two halves.

6.1.7 Screw on the cable clamp flange (without twisting the cable), and tighten the cable clamp screws to secure the cable.

7.0 CONNECTING THE SPEAKER

Connect the three-conductor phone jack to the two wires from the speaker.

Solder one of the speaker wires to the jack terminal that is connected to the tip of the jack.

Solder the second wire to the jack terminal that is connected to the conducting area just above the tip.

No connection is made to the jack ground.

Install the speaker where it can be heard by the sonar operator.

PART B: SEACHEST INSTALLA-

WESMAR

HD800

TION

Part B will outline where to locate your seachest, and what size seachest you should obtain for your model of sonar. For fiberglass boats, you can order a fiberglass seachest from WESMAR. Seachests for wooden, steel, or aluminum boats are constructed at the shipyard, according to the specifications given in the following pages.

1.0 SEACHEST LOCATION

For vessels of 150 tons or more, the seachest should be installed 1/10 to 1/5 of the ship’s overall length back from the bow.

On vessels of 50 to 150 tons, the seachest should be installed 1/5 to 1/3 of the ship’s overall length back from the bow.

With smaller vessels up to 50 tons, the seachest should be installed 1/3 to 1/2 of the ship’s overall length back from the bow.

Mounting the seachest too far forward will expose the soundome to turbulence and air bubbles. In-stalling the seachest too far aft will place the soun-dome close to the engine and propeller. They are sources of noise and can limit sonar performance.

Locate the seachest away from water intakes, discharge lines, or zinc plates welded to the hull.

Air bubbles and water turbulence caused by these objects during vessel movement will reduce sonar performance.

Avoid installing the seachest in the vicinity of exist-ing transducers.

Sounders and other sonar equipment, when oper-ated at the same time, may interfere and cause a pattern to appear on the HD800 display screen each time they transmit.

Install the seachest next to the keel.A seachest installed too far from the keel will have

THE SEACHEST IS NORMALLY INSTALLED ABOUT 1/3 OF THE WAY BACK FROM THE BOW.

Special Circumstances:On seining boats, install the seachest on the same side of the vessel used for setting the net.

The soundome can then scan the net without being blocked by the keel when the vessel rolls.

For engine room installations, place the seachest forward of the engine.

This will eliminate possible me-chanical vibration and electrical interference.

For fish hold installations, a watertight box must be built around the complete soundome assembly.

Fit a drain plug to the bottom of this box to provide drainage. A lamp or some kind of heat source is also recommended.

NOTE: This is generally not a safe location for the hoist assembly.

WESMAR


NOTES FOR FABRICATION:

1. Use 6-inch Schedule 80 steel pipe (5.761 I.D. nominal).

2. Minimum length of seachest for standard ram hoist is 53.3 cm (21 inches).

3. Length of seachest for hydraulic hoist is 1 meter (39.4 inches). If the seachest length is not one meter you must talk to WESMAR prior to ordering the sonar.

reduced performance because it will be subject to turbulence, air bubbles, and the rolling motion of the boat. Also, the keel will block the soundbeam as the vessel rolls. Next to the keel is the most effective location.

If the seachest cannot be installed next to the keel, then install it within 1 meter (39.4 inches) of the keel.

2.0 SEACHEST LENGTH

Standard seachest lengths for the following HD800 sonars with standard electric hoist are:

HD800/160-6: 533 mm (21 inch) minimum 1727 mm (68 inch) maximumHD800/110-8: 572 mm (22.5 inch) minimum 1880 mm (74 inch) maximumHD800/60-8: 572 mm (22.5 inch) minimum 1880 mm (74 inch) maximum

Note: The soundome tube supplied with the system will fit the maximum length seachest.

Standard seachest lengths for the following HD800 sonars with hydraulic hoist are:

HD800/160-6, M6: 1000 mmHD800/110-8, M8: 1000 mmHD800/60-8, M8: 1000 mmHD800/110-10, M18: 900 mmHD800/45-14, M18: 1000 mmHD800/27-15, M18: 1000 mm

If the top of the seachest rises above the waterline, then the soundome can be removed while the ves-sel is in the water. For the top of the seachest to be above the waterline, the seachest must be at least as long as vessel draft plus 5 cm (2 inches).

Measure the draft where the seachest is to be installed, taking into account the effect of fully loading the vessel.

3.0 SEACHEST DIAMETER

Pipe diameters do vary, the inside diameter must match that given on Pages 40-44. Correct inside diameter will prevent vibration of the soundome and improve sonar performance.

NOTE: Seachest diameters for the following HD800 sonars are...

HD800/160-6, 6-inch schedule 80HD800/110-8, 8-inch schedule 80HD800/60-8, 8-inch schedule 80HD800/110-10, 10-inch schedule 60HD800/45-14, 16-inch schedule 40HD800/27-15, 18-inch schedule 40

WESMAR


NOTE: The Model 18 Hydraulic Hoist does not

require the seachest to support the soun-dome. The soundome tube and soundome are completely supported by the flange bearing assembly.

4.0 SEACHEST FLANGE

For metal seachests, the seachest flange must be made of the same material as the pipe and welded to the seachest pipe.

See Pages 40-44 for flange dimensions. A flange is included with WESMAR’s optional fiberglass seachest.

5.0 SEACHEST POSITION

The seachest must be perpendicular to the water line.Attach the seachest to the hull with standard shipyard procedures. Support the seachest with gussets or stringers to minimize vibration.

The bottom of the seachest must be 1 cm (.5 inches) above the bottom of the keel.

6.0 FAIRING

This section only applies to seachests that extend outside the hull.

Build a 1 meter long fairing around the seachest to reduce turbulence and air bubbles at high speeds.

Turbulence and air bubbles reduce sonar perfor-mance.

For seachest installations next to the keel, run fair-ing from the seachest to the keel in front and behind.

SEACHEST ABOVE THE KEEL

Special Note:The Model 18 Long Stroke Hoist does not require the seachest to support the soun-dome during vessel movement. Therefore, the seachest can be installed flush with the outside of the hull (See below). Maximum travel distance of the Model 18 is 1.5 meters (59 inches). This long extension makes the flush-mounted seachest possible.

M18 LONG STROKE HOIST SEACHEST INSTALLATION

WESMAR

HD800

For installations away from the keel, place fairing completely around the seachest.

DO NOT taper the leading and trailing edge of the fairing to the hull (this will drag air bubbles down into the soundbeam). Run metal rods or plates cut at a 45 degree angle from the fairing to the hull to prevent hang-ups on wire rope and deflect debris.

Cover the bottom of the fairing around the seachest.This will help prevent turbulence caused by open cavities.

7.0 BULBED BOW VESSELS

The bulb bow lifts water and draws air bubbles down the keel. These bubbles spread widely over the bottom of the vessel and interfere with sonar performance

WESMAR recommends using only the Long Stroke Hydraulic Hoist in all bulbed bow vessels.

PART C: LEAD SCREW HOIST

BULBED BOW VESSELS DRAW DOWN AIR BUB-BLES THAT CAN OBSCURE THE SOUNDBEAM. LONG STROKE HOISTS GET BELOW THESE BUBBLES.

NOTE: Vessel vibration is more critical on lower frequency sonars (45kHz and lower). This vibration can be transferred to the soundome through the hollow fair-ing. This vibration can be dampened by fi lling the air cavity within the fairing with oil. Oil fi lling ports can be installed through the hull into the fore and aft fairing compartments.

WESMAR’s Optional Long Stroke Hydraulic Hoists

To get longer range and better performance from your HD800 when moving fast or in rough waters, order the sonar with a Hydraulic Hoist.

Air is a perfect sonar target, and will scatter sound energy. Under normal fishing conditions and high speeds, air bubbles often reach a thickness under the vessel that can surround the soundome and af-fect performance. Wind also creates bubbles at the water’s surface.

WESMAR’s Hydraulic Hoists get below the air bubbles to keep the soundbeam clear and provide high performance.

INSTALLATION

NOTE:The lead screw hoist is in the “Up” position when shipped. Keep this in mind during installation.

1.0 SOUNDOME TUBE LENGTH

To determine the minimum length of a soundome tube for a 6-inch soundome, measure the length of the seachest and add:

10.2 cm (4 inches) for a 6-inch soundome

Note: The 8-inch soundome comes standard with the Ram Hoist, see Part D. If there is not enough overhead clearance for a Ram Hoist, a special-order lead screw hoist may be used. To determine the minimum length of a soundome tube for an 8-inch soundome, measure the length of the seachest and Add:

12.7 cm (5 inches) for an 8-inch soundome

Allow at least 10.2 cm (4 inches) of clearance between the top of the soundome tube and the overhead when the soundome is in the raised position.

When the proper length of soundome tube is deter-mined, measure from the threaded end, cut, and file the rough edges off.

If overhead clearance is adequate, the soundome tube may be left uncut.

2.0 ATTACHING SOUNDOME TUBE TO SOUNDOME

2.1 Check Soundome Clearance Before threading the soundome tube into the soundome, check

to ensure there is clearance to allow the soundome to move freely up and down in the seachest. Soundome may be handled by the soundome cable to check clearance.

It may be necessary to fi le down the fi ns of the soundome so it fi ts into the seachest. The clearance around the soundome should not be greater

than 1.6 mm (1/16 inch).

2.2 Attaching Soundome Tube to Soundome

WESMAR

HD800

Thread the jam nut all the way on the soundome tube.

If the Seachest is above the waterline, the threads do not need to be sealed. For seachest below the waterline, wrap the threads with tefl on tape or use Permatex Thread Sealant with Tefl on, Part Number 14H.

WARNING

Do not use bonding compound when threading the soundome tube into the soundome. Chemicals in the bonding com-pound will weaken the neck of the soundome.

Run the soundome cable through the soundome tube, starting at the threaded end.

Screw the soundome tube into the top of the soundome assembly until it fi ts snugly. Avoid cross threading.

Tighten the jam nut until it also fi ts snugly.

WARNING: Screwing the tube down too tightly can damage the soundome and/or jam nut.

2.3 6-Inch Soundome

The 6-inch soundome has a FWD arrow molded into the top of the soundome bell.

This FWD arrow must point forward when the soundome is installed in the seachest.

Make a mark on top of the soundome tube in line with the FWD arrow on the soundome bell.

This mark will be your positioning reference point.

2.4 8-Inch Soundome

The 8-inch soundome has an AFT arrow molded into the top that points to the aft fi n. That fi n, not the arrow, should point aft.

Make a mark on top of the soundome tube in line with the AFT fi n of the soundome bell.

4.0 POSITIONING THE SOUNDOME

To determine how high or low to position the soundome within the seachest, go below the boat and measure the distance between the bottom of the soundome and the end of the seachest.

The correct position of the soundome boot is 3.8 cm (1.5 inches) within the seachest. See Page 55, #1.

If the soundome is too high or too low loosen the top hoist clamp and safety clamp.

Raise or lower the soundome according to your mea-surement.

Align the soundome so that the mark you made on the

Special Note:If you must remove the top hoist clamp from the lead screw to insert the tube, follow these steps:

1. Remove the bronze shear pin from the base of the lead screw.

2. Remove both top hoist clamp and lead screw from the motor shaft.

3. When you replace the top hoist clamp and lead screw, be sure they are in the same position as before.

4. Tighten the locking bolts on the top hoist clamp until they dig into the plastic. When the hoist is in the "Up" position, the lead screw should be even with the top of the hoist clamp.

After positioning the soundome tube, tighten the top hoist clamp and the safety clamp.

Verify the soundome is within the seachest 3.8 cm (1.5 inches)

5.0 LEAD SCREW HOIST MOTOR WIRING

Route the hoist motor wires through one of the small strain reliefs in the bottom of the junction box. Connect the num-bered lugs of the hoist motor to the same numbered terminals on the hoist board in the junction box.

6.0 JUNCTION BOX INSTALLATION

1. The junction box contains the hoist control board and the transmitter/receiver board. Select a convenient location close to the hoist assembly that can be reached by the soundome cable. Do not extend the length of the soundome cable as it may introduce noise and shorten range performance.

2. Do not install the junction box in the fi sh hold or cold storage area.

7.0 CONNECTING POWER TO THE HOIST CONTROL BOARD

The hoist control board is the same for 12 VDC or 24 VDC operation. Only the hoist motor must be ordered for 12 VDC or 24 VDC operation. Connect power to the Junction Box.

The power source for the hoist system need not be the same as the power source for the console. Use the wire chart on Page 35.

Route the hoist power cable through one of the small strain reliefs in the bottom of the Junction Box.

For DC hoist, attach positive [+] lead to Terminal 30, and negative [—] to Terminal 31.

Be sure of correct polarity.The hoist control board is fused with a 15 amp slow blow for both 12 VDC and 24 VDC operation.

8.0 SOUNDOME WIRING

WESMAR


Route the soundome cable through the left large strain relief in the bottom of the Junction Box.

Connect the numbered lugs of the soundome cable to the same numbered terminals on the Hoist Board in the Junction Box.

In addition to the numbered wires, there is one wire, brown in color, labeled "GND", inside the J-box. This brown wire is connected to the ground post at the bottom of the J-box.

9.0 LEAD SCREW HOIST OPERATION CHECK

6-Inch Soundome: Total travel distance up or down is 20.3 cm (8 inches). See Page 55, #5.

8-Inch Soundome: Total travel distance up or down is 28.0 cm (11 inches). See Page 55, #5.

The hoist motor is calibrated at the factory for correct travel distance, but you should check it after installation. Incorrect travel distance means your soundome may not be going low enough into the water to allow the soundbeam full clearance.

Tighten the packing gland only until it slightly weeps water.

A packing gland that is too tight will create excess friction on the soundome tube. This fric-tion may cause damage to the hoist motor or blow the hoist fuse on the hoist board.

9.1 Hoist Operation Check Procedure

To check hoist travel, follow these steps before returning your vessel to the water:

WESMAR

HD800

TOP HOIST CLAMP, SIDE VIEW

9.1.1 Be sure there is enough room beneath the boat to lower the soundome.

9.1.2 Turn off power to the hoist system and console.

9.1.3 Disconnect the upper hoist limit switch wire (blue) from Terminal 27 on the hoist board. Once this is disconnected, the hoist will only move down when powered.

9.1.4 Disconnect the +12VDC wire of the inter-connect cable from Terminal 2 on the hoist board. DO NOT let this wire touch any other terminal, wire, or ship’s ground.

9.1.5 When performing the next steps, do not let the hoist safety clamp press into the packing gland with the motor running. This could damage the hoist assembly.

9.1.6 Make sure wires from Terminal 2 and Terminal 27 are not touching any other wire.

Turn on the hoist and console, and push down the HOIST Switch on the console front panel.

Now there is +12VDC on the wire you pulled from Terminal 2, and hoist motor voltage on Terminals 30 and 31.

9.1.7 When voltage is applied to the hoist, check the hoist down light on the console. It should be off.

If the light is on, adjust the light switch located on top of the stainless steel angle iron on the hoist. Move the switch bracket up or down until the light goes out.

WESMAR


9.1.8 Touch the +12VDC lead to Terminal 2. This will operate the hoist relays and power the hoist motor, lowering the soundome.When the bottom of the safety clamp is within 7.5 cm (3 inches) of the packing gland, remove the wire from Terminal 2.

Move the hoist motor in small steps by tap-ping the 12VDC wire to Terminal 2 until the motor stops driving.

Do not let the safety clamp press into the packing gland.

9.1.9 When the hoist stops, there must be at least 1.25 cm (.5 inches) between the safety clamp and the packing gland.

The hoist should automatically stop lowering before it reaches bottom.

If the safety clamp does not stop, or if it is less than 1.25 cm (.5 inches) above the packing gland, you must reposition the top hoist clamp on the lead screw.

Check the "hoist down" light on the console. The red light should be on.

To Reposition Top Hoist Clamp:

Determine how much space you need to add between the safety clamp and packing gland.

Disconnect the lead screw from the hoist motor by removing the bronze shear pin.

Rotate the lead screw counterclockwise (as viewed from above) one complete turn for each 3.2 mm (1/8 inch) of extra length needed.

Attach the lead screw to the hoist motor, using the shear pin.

You will need to repeat the Hoist Operation Check if you perform this or any other correction.

Locate the following markings on the soundome:

6-inch soundome, "FWD" stamped on the plastic bell to indicate forward.

8-inch soundome, "AFT" that points to the fin on top of the dome to indicate the stern.

10, 14, 15-inch soundomes, "FWD" stamped on the side of the dome to indicate forward.

Make a mark on the soundome tube in line with the FWD or AFT mark on the bell.

Use this as your reference for aligning the soun-dome with the fore or aft of the vessel.


Lower the soundome and hoist assembly into the seachest with a block and tackle.

It may be necessary to file down the teflon shoes on the spider assembly so it fits into the seachest on the M8. The clearance around the spider assembly should be greater than 3 mm (1/8 inch).

Position the soundome so that the mark you made on top of the tube is lined up with the bow or stern of the

The three bottom limit switches are prewired at the factory and connected to the same numbered terminals in the J-Box with the terminal strip.

16.0 POWER BOOSTER INSTALLATION

The power booster is optional equipment for the HD800 series with the exception of the HD800/27-15 (27 kHz). Important: Before turning on the HD800/27-15 sonar the power booster must be installed. Operating the HD800/27-15 without the power booster for any length of time may damage the console power supply.

Using the power booster on the HD800 systems will extend your range capabilities. The power booster is a strong power supply that supplies a large amount of current to the HD800 transmitter.

16.1 Power Booster Voltage

Operating voltage of the power booster is prewired at the factory for 110VAC or 220VAC. Check the operating voltage before connecting ships AC to the power booster. To determine the correct voltage check the voltage se-lect jumpers on the power booster board. Jumpers are located top center below the four place terminal strip

16.2 Installing The Power Booster

The power booster should be installed within one meter from the HD800 junction box. The interconnect cable from the power booster to the junction box is two meters long. Do no extend this cable.

16.3 Connecting Power to the Power Booster

From the factory the power booster is wired with a two meter cable terminated with a U.S. type 110VAC plug. Remove this plug and wire directly to ships AC supply. Confi rm the ships AC supply is the same as the power booster voltage select jumpers. Wire size must handle 3 amps at 110 VAC and 1.5 amps at 220VAC.

factory that connects to the junction box. Route this cable through one of the small strain reliefs in the bottom of the junction box.

16.4.3 Important The following wiring con-nections must be done correctly. Damage to the power booster, transmit/receive PCB or console may result if incorrectly wired.

There are two types of transmitter/receiver boards for the HD800 sonar. The two types of boards are the same with the exception of the terminal strips. The earlier board has one terminal strip, TB2 where both the soundome cable, interconnect cable and power booster wires are connected to. In this confi guration some terminals have two wires going to the same terminal. The later board has two ter-minal strips, TB2 and TB1. By using two terminal strips there is more room to make the connections if a bower booster is used.

Wiring a power booster to the one terminal strip T/R board.

1) Remove the red wire #4 from the terminal and connect it to the unused terminal labeled NC on TB2 (between #5 & #19). This red wire is from

the interconnect cable.2) The power booster has six wires in the cable.

Five of the wires are numbered, #1, #2, #3, #4, #20. Connect each of the number wires to the same number on the terminal strip TB2.

3) The sixth wire from the power booster is labeled with a (+) sign. Connect this wire to the terminal labeled NC.

Wiring a power booster to the two terminal strip T/R board.

1) Remove the red wire #4 from the terminal strip on TB2 and connect it to the terminal labeled TERM #4 on TB1.

2) Connect all six wires from the power booster to

TB1. Each wires is labeled and connects to the same numbered terminal on TB1. One wire is marked with a (+) and is connected to the termi-

nal marked with a (+) on TB1.

17.0 RESERVOIR

The vented plastic thumb screw on the reservoir of the hydraulic pump has been replaced with a metal allen screw. This is to keep the reservoir from leak-ing when the hydraulic motor is removed from the hoist system for shipment. After installing the hoist system, take out the allen screw on the reservoir of the hydraulic pump.

Insert the plastic thumb screw provided by WESMAR.

This thumb screw is vented so the hydraulic reservoir can breathe, which is necessary for proper operation.

18.0 PRE-OPERATION HYDRAULIC INSPECTION

To avoid permanent damage to your hoist hydraulics, follow these steps to check that the system is installed correctly:

18.1 Visually check the hydraulics for leaks.

18.2 Examine limit switch hookup to hoist board for broken wires.

18.3 Check proper location of limit switches.

Make sure the switch arms are not bent, and are aligned so they will switch when the top tube clamp approaches.

18.4 Be sure the packing gland is not too tight.

18.5 Confi rm allen screw on hydraulic pump reservoir has been replaced with plastic thumb screw.

18.6 Check the soundome cable for free movement and no chance of snagging when lowering or lifting the hoist.

18.7 Check the hydraulic lines for free movement when lowering or lifting the hoist.

HYDRAULIC HOIST SYSTEM OILRESERVOIR

WESMAR

HD800

19.0 SOUNDOME OPERATION CHECK

Be sure your hydraulic, M6 and M8 soundomes move at least 500 mm (19.7 inches) up or down when they raise or lower. See Page 77. The M-LS must travel 920 mm (36.2 inches). The M18 hydraulic hoist travels 800 mm (31.5 in)

The M18 LS has three travel distances, depending on operator selection.

The hoist motors are calibrated at the factory for correct travel distance, but you should check it after installation. Incorrect travel distance means your soundome may not be going far enough into the water to allow the soundbeam full clearance. See pages 77.

Tighten the packing gland only until it slightly weeps water.

A packing gland that is too tight will create excess friction on the soundome tube. If the soundome tube stops before the limit switch, damage to the hoist motor may occur.

19.1 Operation Check Procedure

For maximum system performance, follow these steps before returning vessel to the water:

19.1.1 Be sure there is enough room beneath the boat to lower the soundome.

19.1.2 Turn off power to the hoist system and console.

19.1.3 Disconnect the upper hoist limit switch lead (blue) from Terminal 27 on the hoist board.

Once this is disconnected, the hoist will only move down when powered.

19.1.4 Disconnect the +12VDC lead of the inter-connect cable from Terminal 2 on the hoist board.

DO NOT let this lead touch any other terminal, wire or ship’s ground.

WESMAR


19.1.5 When performing the next steps, do not let the hoist descend so far that the motor continues to run after it touches the lower stop.

This could damage the hoist assembly.

19.1.6 Make sure leads from Terminal 2 and Ter-minal 27 are not touching any other wire.

Turn on the hoist and console, and push down the hoist switch.

Now there is +12VDC on the wire you pulled from Terminal 2, and hoist motor voltage.

19.1.7 When voltage is applied to the hoist, check the hoist down light on the console. It should be off.

Move the hoist motor in small steps by tapping the 12VDC wire to Terminal 2 until the motor stops driving.

Do not let the tube clamp press into the shock tube.

19.1.8 When the hoist stops, there must be at least 1.25 cm (.5 inch) between the tube clamp and packing gland.

19.1.9 If the safety clamp does not stop, or if it is less than 1.25 cm (.5 inches) above the packing gland, you must reposition the bottom limit switch.

Check the "hoist down" light on the console. The red light should be on.

20.0 TROUBLESHOOTING

20.1 Motor runs, but will not raise or lower hoist: ~ Solenoid valve stuck ~ Fluid level of reservoir is too low ~ Solenoid valve is not properly con-nected to hoist board ~ Packing gland cap is too tight ~ Rack was bent during installation

WESMAR

HD800

~ Motor not mounted vertically with reservoir toward bottom ~ Obstruction in the seachest ~ Allen screw on hydraulic reservoir has not been replaced with thumb screw, thereby creating a vacuum in the reservoir

20.2 “Raise” and “Lower” are reversed:

~ Solenoid valve miswired to hoist board ~ The two hydraulic hoses need to be reversed

20.3 Motor continues to run after raising or lowering:

~ Limit switches not connected, or not connected properly to the hoist board

~ Broken wires to limit switches ~ Limit switches on hoist rack not

properly aligned and are not triggering when the top hoist clamp approaches

20.4 Soundome will not stay up:

~ Dirty check valves ~ Check for leak in the hydraulic cylinder.

21.0 RESERVOIR OIL MAINTENANCE

The hydraulic system is fi lled with oil before shipment, and should not require any more for proper operation. Check the oil level after installation, and once a month after that, by removing the venting plug on the side of the reservoir. Fluid level should be just below the opening.

For your HD800 AC or DC hydraulic hoist system, use Chevron Automatic Transmission Fluid, “Dexron II,” or its equivalent.

21.1 Filling the Oil Reservoir

WESMAR


Remove the oil fi ll plug located on the side of the reservoir.

Pour oil through a funnel until it begins to fl ow out the oil fi ll hole. Air will be able to escape out the vented thumb screw above.

Replace the oil fi ll plug.

22.0 BLEEDING THE HYDRAULIC SYSTEM

The hydraulic hoists are self-bleeding. If air bubbles do get into the hoses, they will be expelled when the hoist has been raised and lowered several times.

PART F: ANTIFOULING PAINT

WESMAR does not recommend painting the soundome boot. However, a thin, even layer of antifouling paint can be applied to the soundome boot ONLY if marine growth is substantial.

A thicker layer can be applied to the soundome bell.

NOTE: Use a non-lead base paint designed for plastic surfaces.

Section IVFIELD ADJUSTMENTS/

CALIBRATION

WESMAR

HD800

PART A: CALIBRATION

All HD800 sonars are calibrated at the WESMAR factory in our test tank before shipping. However, WESMAR does rec-ommend checking adjustments after installation. A sonar that is correctly adjusted will give maximum range performance.

Before proceeding with calibration, set the sonar to the following settings:

Menu 1: 1. Screen Mode Full 3. Noise Filter None 4. Target Filter Off Menu 3: 5. "A" Colors Select 8

Use the Function Knob on the front panel and select:

Speed 1 Power 100% Pulse 100% TVG Correct number for frequency Threshold 3

1.0 POSITIVE 5 VDC ADJUST (CONSOLE)

Connect the positive lead of a Digital Volt Meter (DVM), to the back side of R20 (see console drawing for location). Connect the Negative Lead of the DVM to the TP1 or the back panel.

Adjust RV2 for a Positive 5.1 VDC.Note: This adjustment affects TVG Offset, next step. Both adjustments must be done in order.

2.0 TVG OFFSET (CONSOLE)

Connect the positive lead of DVM to TVG output, blue wire labeled "Y", located to the right back of the console circuit board. Connect the negative lead to "TP1," receiver ground, located right front of the console circuit board.

Set both Near and Far Gains of Sonar A to zero, counter-clockwise.

WESMAR


Adjust RV4 TVG Offset to + 0.02 VDC (slightly positive).

3.0 TRANSMITTER, PREAMP, RECEIVER ADJUSTMENT (J-Box)

Locate a solid target 100-200 meters, (300-600 feet) away. Select the smallest scanning sector and position the sector over the target with the Bearing Knob. Adjust Tilt, Bearing, Near and Far Gain for Sonar A for good target marking on the display.

Connect the positive lead of an Analog Volt OHM Meter (VOM) to TP5, Receiver Output (see T.P.R. drawing for loca-tion). Connect the negative lead to TP1, Receiver Ground. Select the 3 Volt DC scale on the VOM. The DC scale will give better results than the AC scale.

Adjust the following, in order, for maximum defl ection on the VOM. To verify your tuning, repeat the procedure.

1. T1 Transmitter 2. L1 Preamp 3. L2 Preamp 4. L3 Preamp 5. T5 Receiver 6. L4 Receiver 7. L5 Receiver

Note: Adjustment must be made with a nonmagnetic tool.

4.0 RECEIVER GAIN ADJUSTMENT (CONSOLE)

Use the front panel Function Knob, and for Sonar A set: Speed - 1 Pulse width - 0 (zero) percent TVG - 0 Threshold - 3

Set Near Gain, Sonar A, to 100 (maximum).

Set Far Gain, Sonar A, to 75.

WESMAR

HD800

Select a range of 100 meters (300 feet) for Sonar A.

Adjust RV5 for Light Noise on the screen. Light Noise is defi ned as light blue and green speckles (dots or snow) on the screen. Some speckles may be red in color.

Check Receiver Gain by rotating Far Gain fully clockwise to 100. The Light Noise will increase in color with more red. Red Noise should total less than 40 percent of the noisy area. If there is too much red, back-off on RV5 slightly.

5.0 POWER SUPPLY FREQUENCY ADJUSTMENT (CONSOLE) This last adjustment is to verify that the power supply in the sonar does not interfere with targets:

Set Sonar A for: Pulse width - 0 (zero) percent TVG - 200 Near Gain - 100 Far Gain - 75, Light Noise Range - 200 meters

Adjust RV1, Power Supply Frequency, for the least amount of noise on the screen. Keep this adjustment between the 2 to 5 o'clock position. Power Supply Noise looks like spokes on the outer edge of the screen. If Power Supply Noise was reduced by adjusting RV1, then repeat Step 4.0 above.

This completes the Calibration Procedure of the HD800 Sonar. You will fi nd that a well-tuned sonar will give you the advantage and performance unmatched by other sonars.

HD800 FT Installation NotesIntroduction:Both HD800/160FT-6 and HD800/110FT-8 are

new models to the focused beam line of WESMAR sonars. They are designed to fi t medium-

sized fi shing vessels that have 6 or 8 inch seachests. Both FT models come standard with a rugged, compact hoist that travels 457mm, or 18 inches, into cleaner water. With the new, compact, self-contained hy-draulic power pack, the raising and lower-ing of the soundome can be accomplished in 3 seconds.

Sonar Operation:Sonar operation is the same as other HD800 models.

Section II of the HD800 installation and operation manual applies to the FT models.

Installation:Installation of the HD800 FT system is similar to

other HD800 models. Section III of the HD800 installation and operation manual applies with the exception of the follow-ing notes.

Section IIIPart A: Console and monitor installation (same

instructions for FT)Part B: Seachest installation

1. Seachest LocationThe HD800/160FT-6 will fi t into a 6-inch schedule 80 steel pipe. Note the inside

diameter is 5.761 inches nominal. The HD800/110FT-8 will fi t into an

8-inch schedule 80 steel pipe. Note the inside diameter is 7.625 inches nominal.

2. Seachest LengthMinimum seachest length for the HD800/160FT-6

is 570mm, 22.5 inches. Minimum seachest

WESMAR

HD800

length for the HD800/110FT-8 is 610mm, 24 inches. The length of the seachest must be measured so the correct length of soun-dome will be supplied with the system.

Part C: Does not apply to FT models.Part D: Does not apply to FT models.Part E: Does not apply to FT models.Special Notes:For shipping, the vent screw located on top of the

reservoir has been replaced by a non-vented screw. This non-vented screw keeps the reservoir from leaking during shipping. After installing the hydraulic power pack, replace the non-vented screw with the vented screw. The pressure relief valve is adjusted to 800 psi at WESMAR. The valve can be adjusted using a screwdriver. Valve is located on the left side of the pump. The FT hydraulic power pack does not require a fl ow control valve.

Part F: Hydraulic Hoist Installation1. Soundome Tube Length FT

The soundome tube will be pre-cut and machined at the factory to fi t the length of seachest on board the vessel.

2. Does not apply to FT models 3. Hoist Rack Assembly

Hoist rack assembly for the FT models are as-sembled at WESMAR.

4. Soundome Tube InstallationSame for FT model.

5. Soundome Safety Clamp and Tube Clamp5.1. In addition to the tube clamp, the FT

models use a safety clamp. Slide the safety clamp down the soundome tube. Do not tighten at this time.

5.2. Remove the cross steel plates connect-ing the four angle legs together. Align the four tube clamp guides so the angle legs fi t inside the clamp guides. Im-portant: the tube clamp has two holes

WESMAR


on the side. Make sure when fi tting the tube clamp on the angle legs that one of the holes is to the right of the angle leg that has the limit switches installed. Do not bolt at this time.

6. Attaching Soundome to Soundome Tube6.1 The FT soundome bolts directly to the

welded stainless steel fl ange on the soundome tube. Run the soundome cable through the soundome tube start-ing at the fl ange and out the other end.

6.2 Clean the top of the soundome and remove any debris from the surface and ‘O’ ring. Align the mounting holes of the soundome to the holes of the fl ange.

6.3 Apply anti-seize to the bolts and tighten evenly.

7. Installing the Hydraulic Ram7.1 Remove the strain relief at the top of

the hydraulic ram end cap.7.2 Run the soundome cable through the

strain relief. The hydraulic ram has an indentation where the soundome cable fi ts in at the opposite end. With the soundome cable in the indentation, slide the hydraulic ram into the soun-dome tube at the same time pulling the cable through the strain relief. Slide the ram in until the top of the ram end cap is just above the soundome tube.

7.3 Rotate the ram end cap so the holes in the side align with the holes on the side of the soundome tube and tube clamp. Important: To keep the hydraulic lines from crossing, the ram end cap must be aligned correctly. Correct alignment has the soundome cable strain relief of the ram and cap just in back or to the left of the angle leg that has the limit switches attached.

Locate the angle leg opposite the limit switches. Half way up the leg are two holes side-by-side. Use these holes to bolt the hydraulic power pack mounting bracket.

14. Soundome WiringFollow instructions in manual.Important: In addition to the numbered wires,

there is one wire—brown in color—la-beled “GND”. Inside the soundome this wire is connected to the top metal plate. Inside the J-box, this brown wire is con-nected to the ground post at the bottom of the J-box.

15. Hoist System WiringFollow instructions in the manual.Note: The hydraulic power pack is the same for DC

motors and AC motors. When connecting ship’s power to the DC motors, the nega-tive connection is different for 12V and 24V motors. Connect the negative wire of the 12V bolt motors to the allen bolt on the left side of the hydraulic pump. Connect

WESMAR


the negative wire for the 24V motor to the terminal bolt on top of the motor. See following pictures for location.

16. Power Booster InstallationPower booster does not apply to FT systems.

17. ReservoirThe vented reservoir screw is shipped in a plastic

bag, wire tied to one of the hydraulic hoses. Use automatic transmission fl uid when fi lling the oil reservoir.

18. Pre-operation Hydraulic InspectionThe FT hoist will travel 457mm, 18 inches. Make

sure there is room under your boat for this travel. 18.1. Down Operational Check Pro- cedureFollow procedure in manual.18.2. Up Operational Check ProcedureTurn off the console. Raise the hoist by

tapping the blue wire marked 27 to the terminal 27 on the hoist board. Keep tapping the wire until the top limit switch stops the hoist motor.
