SAFETY INSTRUCTIONS WARNING WARNING Install the specified transducer tank in accordance with the installation instructions. If a different tank is to be installed the shipyard is solely responsible for its installation, and it should be installed so the hull will not be damaged if the tank strikes an object. ELECTRICAL SHOCK HAZARD Do not open the equipment unless totally familiar with electrical circuits and service manual. Only qualified personnel should work inside the equipment.
CAUTION Ground the equipment to prevent electrical shock and mutual interference. Observe the following compass safe distances to prevent deviation of a magnetic compass: Display unit Standard compass Steering compass 2.2 m 1.6 m WORKING WITH THE SONAR OIL Precautions • Keep oil away from eyes. Wear protective gloves when working with the oil. The oil can cause inflammation of the eyes. • Do not touch the oil. Wear protective gloves when working with the oil.

MOUNTING 1.1 Hull Unit General mounting considerations • Noise and air bubbles will affect performance. • Keep the transducer away from oil. Oil can corrode the cable. • Do not expose the transducer to hot water. Hot water can damage the transducer. • Do not turn on the equipment with the transducer exposed to air. Exposing the transducer to air may damage it.
Mounting method A typical mounting method is shown in the outline drawing at the back of this manual. Consult ship’s owner, dockyard and user to determine appropriate mounting method. Pay attention to safety (strength, watertighness) first, followed by ease of maintenance and inspection. Tank length Shorten the transducer tank so the transducer is lowered into water as deep as possible. Cable gland Washer Pay particular attention to the tank length Lt.
Assembling and mounting of hull unit The hull unit is shipped disassembled as the parts shown in the hull unit kit on pages 1-10 and 1-11. Assemble the hull unit as shown in the procedure below. Necessary tools Name Specification Remarks Wrench For M10 (Hex. size 17 mm) Wrench For M20 (Hex. size 20 mm) Pipe Wrench 55 mm Ball Wrench Hex size 4 mm Supplied with hull unit kit 1. Unscrew 10 pieces of socket head cap screws with the ball wrench (supplied) to detach the soundome.
2. Fill the soundome with sonar oil 6 cm below the top of the dome. (Use only the specified sonar oil. Use of other sonar oils may affect performance.) Reattach the soundome.

Wear protective gloves when working with the oil. The oil can cause inflammation of the eyes. • Do not touch the oil.
4. Fasten the main shaft to the soundome assembly as follows: a) Attach screw lock nut to main shaft. b) Fully screw main shaft into the soundome neck, and then unscrew by four turns. Coat threads with adhesive (HIGH SUPER). c) Screw in main shaft completely and tighten the lock nut with spanner. d) Tighten socket-set screw on lock nut. e) Fasten two reinforce metal fittings to connect the main shaft and the soundome assembly securely (Not using the stopper washer).
5. Clean the main shaft and pass it through the main body flange. Check that O-ring is in position. Main body flange Figure 1-7 Passing main shaft through the main body flange 6. Set the grease cotton to the main body flange and tighten the grease cotton retainer temporarily. Space joints of grease cotton 120° apart and push them into body flange. Wind grease cotton onto main shaft and cut it as shown below. Flat washer Figure 1-8 Installing grease cotton on the main shaft 7.

Fasten the hull unit to the transducer tank, orienting it so the ship’s fore-aft line crosses the front panel of the raise/lower drive block at an angle of approximately 45 degrees.
10.Install the raise/lower drive block as follows: a) Rotate the main shaft so the bow mark faces ship’s bow. b) Install the raise/lower drive block onto the main body flange. c) Fix the main shaft with the shaft retainer. d) Loosen the fastening band, slide it up to the shaft retainer and fasten it. e) Check that the distance from the top of the main shaft to the top of the shaft retainer is as follows: 1.
Grease cotton retainer 7 to 9 mm Grease cotton Figure 1-13 Tightening the grease cotton retainer Checking manual raise/lower of transducer with hand crank Perform this check after all wiring has been completed. Ship’s mains power must applied to the hull unit, otherwise the magnetic brake of the raise/lower motor activates, disabling the manual raise/lower gears. 1. Turn off the breaker on the hull unit. 2. Detach the brake-off switch cover. 3.

Transceiver Unit Mounting considerations • The mounting location should be well ventilated and dry. • The unit can be mounted on a bulkhead or the deck. The unit weighs 8.5 kg so reinforce the mounting location if necessary. • Secure the maintenance space shown in drawing below for ease of maintenance and service. 350 282 75 32 505 475 342 32 100 75 (30) 66 20 310 120 1.
1.3 Display Unit Mounting considerations Select the mounting location considering the following conditions: • Select a location where the display unit can easily be operated while observing the fishing ground or area surrounding the vessel. • Locate the unit at least 1 meter away from equipment which contains magnets (radar magnetron, loudspeaker). • A magnetic compass will be affected if placed too close to the display unit.
1.5 Motion Sensor MS-100 (Option) The MS-100 measures ship’s pitching and rolling angles with sensors using the principles of the gyroscope. The MS-100 is free from error caused by ship’s vertical and horizontal motion. Therefore, it can be installed at any convenient location. However, ship’s semi-permanent inclination due to loading imbalance cannot be detected. Compensate for this as described in Chapter 3. Mounting considerations FORE • Vibration in the mounting area should be minimal.

1.8 Clinometer BS-704 (Option) The clinometer detects ship’s inclination caused by ship’s rolling and pitching and its output is used to stabilize the sonar beam against rolling and pitching. The clinometer is, in principle, a pendulum. It measures the inclination of the ship by sensing the direction of gravity acted on it and therefore when installed on a ship, it should be placed on or near the rotation axes of the ship’s rolling and pitching.
Cautions: (1) The vicinity of the hull unit (on the ship’s bottom) is too low and should be avoided, since the polarity of the measured value is reversed. (2) When it is impossible to install the clinometer on the intersecting point of both rolling and pitching rotational axes, a special effort should be made to install it at place where the vertical distance to the intersecting point is minimum. (3) The clinometer should be installed on the horizontal plane.
WIRING 2.1 Wiring Among Units • The figure on the next page shows wiring among units. • The signal cables are fitted with connectors. Connect the cables to the display, transceiver and hull units referring to the interconnection diagram and the drawing on page S-1. • The power cable should be arranged locally. Use power cable type DPYCYS-2 and DPYCYS-1.25 (both Japan Industrial Standard cables) or equivalent cables. Attach supplied power connector as shown below. Ground armor through connector clamp.

Horizontal beamwidth 06P0192 When the user wishes echoes to be displayed in high resolution, turn R40 on pcb 06P0192 clockwise to sharpen horizontal beamwidth. Do not turn it excessively clockwise, or an echo which should be displayed as a single solid mass may become hollow or split into smaller, fewer masses. Normally, set R40 at the midpoint of its travel. HI LO JP2 R61 R40 Photo No. 2058 Figure 3-1 Transceiver unit, cover opened 3.3 Heading Alignment 1. Locate a target (buoy, etc.
