1.2 Hull Unit
Note: Handle the transducer carefully. Rough handling will damage its sensitive components.

1.2.1 Installation considerations
Decide the location of the hull unit through consultation with the dockyard and shipowner. When deciding the location, the following points should be taken into account.

• Select an area where propeller noise, cruising noise, air bubbles, and interference from turbulence is at a minimum. Generally, the point at 1/3 to 1/2 of the ship’s length from the bow on or near the keel is optimum. On-the-keel installation is advantageous for minimizing oil consumption in comparison with off-the-keel. If the hull unit can not be installed on the keel, the center of the retraction tank should be within 600 mm from the keel to prevent a rolling effect. For a large ship with deep drafts, the hull unit can be installed at the bow.

• Select a place where the hull bottom is flat and the draft is sufficiently deep. Normally, the transducer should protrude at least 500 mm beyond the keel to minimize the effect of air foam and bubbles.
• Select a place where interference from other transducers is minimal. The hull unit should be at least 2.5 m away from the transducers of other equipment.
• No obstacle should be in the fore direction since it causes a shadow zone and aeration, resulting in poor sonar performance.
• Select a mounting location, considering the ship’s bottom structure and other sonar equipment. If the ship’s bottom structure and transducer for other sonar equipment is projected more than the FSV-75 transducer, the FSV-75 cannot display sonar echoes correctly. Similarly, if the FSV-75 transducer blocks another sonar transducer, other sonar equipment cannot display the sonar echoes correctly.
• In the case of a bilge keel, select a location as far from the bilge as possible.
• Select a location away from indents and protrusions on the hull, especially indents, as they can create noise interference and cause poor sonar performance.
• Referring to the outline drawings at the back of this manual, allow sufficient space for maintenance and service.
• If the ambient temperature will be below 0°C, provide the sonar compartment with a heater to keep the temperature above 0°C. The hull unit can not work if the ambient temperature is below 0°C.
• Prepare a secure and firm safety fence for the hull unit, to prevent accidental injury from the moving hull unit. The safety fence should be easily removable for maintenance and allow room for the connected cables to swing freely with pitch, roll, and heave. The power switch on the control box should be operable from outside the safety fence.
• After you mount the hull unit, be sure to install anti-vibration stays.

1.2.2 Guideline for how to shorten the retraction tank
The recommended tank length for 800 mm and 1100 mm travel hull units is as follows:

• 800 mm travel: 900 mm retraction tank is recommended.
• 1100 mm travel: 1200 mm retraction tank is recommended.
  Shorten the tank as necessary so that the transducer positions well below the keel when it is fully lowered. The following table provides guidelines for shortening the tank.
  Refer also to the retraction tank installation drawing at the back of this manual.Installation Method
  Travel| | | |
  ---|---|---|---|---
  800 mm
  travel| Cut 0-100 mm from the end.| Cut 0-100 mm from the end.
  Note that the length “D” must be less than 200 mm.
  1100 mm
  travel| Cut 0-100 mm from the end.| Cut 0-100 mm from the end. Note that the length “D” must be less than 500 mm.

Note 1: Adjust the position for the TX limit switch, according to the retraction tank length. For how to adjust the position for the TX limit switch, see section 1.2.8.
Note 2: When the maximum length is removed and “D” is at a minimum, the effect of aeration is minimized because the transducer fully protrudes in water.

Guideline for the installation of the retraction tank

• If the keel plate on the inside of the hull is not adequate for installing the retraction tank, install a secondary keel plate.

• Install the retraction tank where the keel plate and hull frame intersect.

• If there is no suitable location where the hull frame and keel intersect, install suitable “T” shaped reinforcement ribs, then weld the base of the frame to the reinforcement
  ribs and the sides of the reinforcement ribs to the hull walls or other nearby reinforcement ribs. The reinforcement ribs should be secured in the fore, aft, port, and starboard directions.

• Install the reinforcement ribs as near as possible to the top of the retraction tank, allowing 150 to 200 mm space for tightening of nuts and bolts.

• Fit a doubling plate (a plate added to another to give extra strength or stiffness) to the location where the retraction tank is welded to the hull bottom. While it is recommended that both sides attach to the hull, consult with the installer regarding length and diameter.

• The thickness for doubling plates and reinforcement ribs is 12 mm minimum.

1.2.3 Preparation when an FRP retraction tank (inner diameter: 306 mm) is used
Note: The following procedure is required only when an FRP retraction tank (inner diameter: 306 mm) is used. If a steel retraction tank (inner diameter 316 mm) is used, skip the following procedure.

1. Unfasten the six countersunk head screws (M5×10) to remove the contact plate (four locations). Discard the removed contact plates and screws.
2. Remove the three hex socket bolts (M4×8) that secure the spring assembly (four locations).
3. Rotate the four spring assemblies by 90° in the direction of the arrow on the bottom of the spring assembly, then secure the spring assemblies using the hex socket bolts that were removed at step 2. If you cannot rotate the spring assembly by hand, use a tool such as a wrench whose hex size is 19 mm.
4. Check that the four rollers on the side of the tank guide are pushed inwards approx. 5 mm.

1.2.4 Preparation before installing the hull unit on the retraction tank
An anti-vibration guide is attached to the FSV-75 hull unit shaft. The rollers on the guide can prevent the hull unit from being installed into the retraction tank. For this reason, the rollers must be pushed inwards BEFORE installing the hull unit into the retraction tank.
Note: The following procedure is also required when you remove the hull unit from the retraction tank.

1. Unfasten the two wing bolts at the top of the hull unit, then rotate the motor cover.
2. Pull the release lever away from the holder.
3. Attach the ratchet wrench, referring to the figure at step 6.
4. Push the release lever up or down to release the motor brake, keeping a firm hold on the ratchet wrench.
5. With the motor brake released, turn the ratchet counter-clockwise to raise the shaft (tank guide).
6. While keeping a firm hold on the ratchet wrench, let go of the release lever.

CAUTION
Do not release the ratchet wrench before letting go of the release lever. If you let go of the release lever, the ratchet wrench spins freely and may cause serious injury.

*: An extension bar whose length is approx. 40 mm may improve work efficiency.

7. Repeat step 4 to step 6 to raise the shaft (tank guide) until the gap between the tank guide and pedestal is approx. 13 mm (for the steel retraction tank (inner diameter: 316 mm)) or 8 mm (for the FRP retraction tank (inner diameter: 306 mm)). When the shaft is raised, the roller springs are forced downwards by the pedestal, pushing the rollers inwards.

• Steel retraction tank (inner diameter: 316 mm): 13 mm
• FRP retraction tank: (inner diameter: 306 mm): 8 mm

Note: Roller springs reactively push against the shaft, which can add load to the ratchet as the shaft is raised. Keep this in mind when raising the shaft and continue to raise it until the gap between the pedestal and the tank guide is approximately 13 mm (for the steel retraction tank (inner diameter: 316 mm)) or 8 mm (for the FRP retraction tank (inner diameter: 306 mm)).
8. Reattach the release lever to the holder.
9. Replace the ratchet wrench and motor cover.

1.2.5 How to install the hull unit on the retraction tank
Weld the retraction tank and allow sufficient time for cooling. Install the hull unit as follows:

Note: For installation using an existing CSH series hull unit retraction tank, see section 1.10.

1. Clean the flange and O-ring groove of the retraction tank (welded to hull). Use waste cloths moistened with ethyl alcohol.

2. Coat the O-ring and O-ring groove with lithium grease, then place the O-ring in its groove on the tank flange.

3. Orient the hull unit so that the bow mark (inscribed on its flange) points toward the ship’s bow.
   Note: If the bow mark on the hull unit flange is not facing the ship’s bow, rotate the transducer so that the bow mark on the transducer points toward the ship’s bow
   (see section 1.2.9).

4. Confirm the following points, then place the hull unit on the retraction tank.
   • Clean the flange platform.
   • Wipe the undersurface of the hull unit flange with clean waste cloths.
   • Keep O-ring in its groove.

5. Coat the threads of the bolts with a slight amount of lithium grease to prevent scorching, then secure the hull unit to the retraction tank, referring to the following figure.
   

6. Lower the transducer, then confirm that the rollers on the tank guide are not projected from the retraction tank. The tank guide must be positioned 30 mm inside from the bottom of the retraction tank.
   Note: The position for the lower limit switch can be raised 100 mm by using the bolt holes on the flange assembly.

1.2.6 How to remount the emergency switch
The emergency switch is attached to the starboard side of the hull unit. If the starboard side clearance is not sufficient for switch operation, the switch may be remounted on the port side.

1. Unfasten the four screws to remove the box base.

2. Unfasten the two screws to remove the box cover.
   

3. Remount the emergency switch to the port side.
   Note: For the 800 mm travel hull unit, rotate the emergency switch by 90° so that the emergency switch cable passes through the rear side of the hull unit (see the figure at step 4).

4. Secure the emergency switch cable, using the two wiring bands. The wiring band must be secured to the hull unit, using pan head screws (M4×12).
   

1.2.7 How to install the stays (anti-vibration and anti-shock measures)
This measure must be done after installing the hull unit to prevent damage from vibration or impact shock to the transducer. Stays should be as sturdy as possible (75×75×9 mm minimum recommended). Install a minimum of two stays, one in the aft direction, and one in the fore direction. Where possible install two more stays (one in the port and one in the starboard direction), making a total of four stays. Where the hull unit is installed off-center from the bow- stern line, install the stays at right angles with the bow mark on the hull unit.

Where horizontal installation of the stays is not possible, install the stays in a diagonal manner to reduce vibration in the hull unit.

1.2.8 How to adjust the TX limit switch position

Adjust the TX limit switch position so that the switch is turned on where the transmitting face of the transducer is projected from the hull unit.

Distance to the transmitting position (A) can be selected from 450 mm, 425 mm, 400 mm, 375 mm, or 350 mm. The distance to the transmitting position can be calculated with the following formula. Select the value closest to the calculation.

• 800 mm travel: A = T- 550 mm
• 1100 mm travel: A = T – 850 mm For example, when the tank length (T) for the 800 mm travel is 920 mm, the calculated value is “ A = 920 – 550 = 370 mm”. Therefore, adjust the TX limit switch so that the distance to the transmitting position is 375 mm.

Note: The transducer can transmit when the transducer is projected 270 mm from the retraction tank.

At factory default, the distance to the transmitting position is 450 mm (tank length: 1000 mm (800 mm travel) or 1300 mm (1100 mm travel)). To adjust the distance to the transmitting position, unfasten the two mounting screws (M6) to remount the TX limit switch.

1.2.9 How to adjust the bow mark directly on the transducer
When you cannot face the bow mark on the hull unit flange to the bow direction due to installation space, rotate the transducer so that the bow mark on the transducer points toward the ship’s bow.

1. Release the transducer cable from the three cable clamps.
   

2. Lower the transducer manually.
   Note: For how to lower the transducer manually, follow the procedure indicated on the label at the top of the hull unit.

3. Mount the transducer on a base to prevent the transducer from falling accidentally.

4. Insert four bolts (M10×80, supplied locally) to the hole on the bottom of the tank guide to push the tank guide rollers inwards.
   Note: Steel bolts are recommended to prevent scorching.
   

5. Unfasten the four hex socket bolts on the top of the main shaft to disassemble the cable gasket assembly.
   

6. Unfasten the 16 hex socket bolts to remove the trunnion receptacle from the main shaft.
   

7. Rotate the transducer so that the bow mark on the transducer points toward the ship’s bow.
   

8. Reattach the trunnion receptacle.

9. Assemble the cable gasket on the top of the main shaft.
   Note: The following marking appears on the cable gasket and transducer cable. Assemble the cable gasket so that each marking points toward the ship’s bow.
   

10. Remove the four bolts inserted to the tank guide at step 4.

11. Raise the transducer manually.

12. Secure the transducer cable with the three clamps indicated at step 1.
    Note: For how to route the transducer cable, see page 2-3.

1.2.10 How to check the soundhole assembly operation
After installing the hull unit, check the soundhole assembly operation before wiring.

1. Prepare a power cable (supplied locally) to supply the power to the soundhole assembly.
   

2. Turn the control box breaker off.

3. Open the control box cover, then make connections referring to the following figure.
   The operation check can be performed regardless of the settings for connectors other than the ones indicated in this procedure.
   Connection with the soundhole assembly
   Following connectors must be connected.
   The hull unit is supplied with the following connectors connected.
   • TB1HFLT board
   • TB8
   • TB10
   Connection with the 48 VDC power supply
   • TB2: Connect the power cable prepared at step 1.
   

4. Turn the 48 VDC power supply on to supply the power to the soundhole assembly, then confirm that the 3.3 V LED on the control box lights steadily.
   When the soundome assembly is powered correctly, an operation check is performed automatically. The decimal point on the display LED flashes during the operation check. The operation check takes approx. one minute.
   

5. After completing the operation check, press the mode select button to change the display mode LED indication to “E”. When the display mode LED shows “E”, when an error is detected, the error code appears on the check result LED. For details about the error codes, see “Error code” on page 1-17.
   Note: If errors are detected during the operation check, the check result LED shows the error code automatically.

6. Turn the 48 VDC power supply off and disconnect the power cable from TB2.

7. Reattach the control box cover.

MOUNTING BASE SAMPLE (SHIPYARD SUPPLY) (DIMENSIONS ARE DECIDED BY SHIPYARD) (FOR FLOOR MOUNT; REFER TO ANOTHER DRAWING FOR BULKHEAD MOUNT) L-ANGLE SIZE (UPPER): 60 X 60 (t5) OR MORE. BASE-ANGLE (STEEL I-BEAM) SIZE (LOWER): 150×150 (W6x15-in) OR MORE

INSTALLATION METHOD OF RETRACTION TANK

1. Install tank to hull plate with fillet welding taking the following points into account; Flange face is exactly horizontal at normal ship’s trim. Bow mark on side of the flange should be faced deadly ahead. Allow height of flange face from keel bottom “Ht” mentioned in the drawings, otherwise transducer beam is blocked by the keel when the transducer is fully lowered. Tank’s length “Lt” should be less than Ht”. If not so, the bottom end of the tank is placed below keel level. “Lt” is also limited as shown in the drawings so that the transducer can be fully retracted in the tank. (The tank is supplied with 1000/1300 mm long as standard.
2. Fit doubling plate of outer dia. 0700 around the tank on the hull plate. Fit fairing plate reffering to the drawing ‘D’ for installation methods A and ‘B’. Use same material and thickness of doubling and fairing plate as hull plate.
3. Weld the tank into the bulkhead ()around the tank.
4. Allow a clearance of more than 150 mm below the flange face for easy bolting. Sink the inner hull-plate as shown in drawing ‘B’ for a high inner hull plate.
