NOTICE

Do not apply paint, anti-corrosive sealant or contact spray to coating or plastic parts of the equipment.

Those items contain organic solvents that can damage coating and plastic parts, especially plastic connectors.

1.1Display Unit DS-600

Mounting consideration

The display unit can be installed on a desktop, on the underside of a table, or flush mounted in a panel. When you select a mounting location, keep in mind the following points:

???Locate the display unit away from exhaust pipes and vents.

???Select an installation location that is well ventilated.

???Locate the display unit where shock and vibration are minimal.

???Allow enough maintenance space at the sides and rear of the display unit and leave enough slack in cables to facilitate maintenance and servicing.

???Observe the compass safe distances (see page i) to prevent the interference to a magnetic compass.

???The nominal viewing distance for the display unit is 1 m. Select a suitable mounting location considering that distance.

Flush mount

See the outline drawing in the back of this manual. Before you fasten the display unit to the cutout, first connect the cables referring to chapter 2.

1. Make a cutout in the mounting location as shown in the illustration below.

1. INSTALLATION

Note: Dimensions for the cutout are different depending on the mounting location, indoor or out- door. For the outdoor mouting, ask dockyard to construct a waterproof case for the display unit.

2.Make four pilot holes for self-tapping screws (diameter: 5 mm) in the location indicated in the illustration on page 1-1.

3.Insert the sponge to the display unit from the rear side.

4.Set the display unit to the cutout and fasten the display unit with four self-tapping screws (5x20).

5.Set a cosmetic cap to each fixing hole on the front panel. See page 1-3.

Desktop or table underside mount

The display unit can be mounted on a desktop or on the underside of a table using the optional hanger. See the outline drawing for details.

Hanger assembly (Type: OP26-8, Code No.: 000-016-313-00)

1.Remove the hanger mounting plate from the hanger assembly.

2.Fasten the hanger mounting plate to the display unit from the left side and right side with four binding head screws (M5x12).

3.Make a four pilot holes for self-tapping screws (5x20) in the mounting location.

4.Fix the hanger to the mounting location with four self-tapping screws (5x20).

5.Screw knobs into the display unit loosely.

6.Set the display unit to the hanger.

7.Tighten the knobs to fasten the hanger to the display unit.

How to set the cosmetic cap and alarm lid assy.

Set a cosmetic cap to each fixing hole on the front panel as shown in the illustration below.

For the display unit to be used as a sub display, attach the alarm lid (supplied as accessories) to the [ALARM] key to prevent accidental operation of the key.

1.2Transceiver Unit DS-620

Installation considerations

???Since the transceiver unit generates heat, install it in a dry, well-ventilated place. The cooling fans at the top of the unit must not be obstructed, to allow heat to escape.

???This unit is designed for bulkhead mounting to permit dissipation of heat. If bulkhead mounting is absolutely impossible, mount the unit on the floor leaving at least 350 mm clearance between it and the floor to permit dissipation of heat.

???Reinforce the mounting area, if necessary.

???Leave space around the unit for maintenance and checking. Refer to the drawing at the back of this manual for minimum recommended maintenance space.

???A magnetic compass will be affected if the transceiver unit is placed too close to it. Observe the compass safe distances to prevent disturbance to the magnetic compass (page i).

Use four hex. bolts (M10x20) to fix the transceiver unit to the mounting area. See the outline draw- ing at the back of this manual.

1.Screw in lower hex. bolts so there is 5 mm clearance between bottom of screw head and bulk- head.

2.Hang the unit on the bolts, then tighten the bolts.

3.Fasten the unit with upper hex. bolts.

1. INSTALLATION

1.3Distributor Unit DS-610

The distributor unit can be mounted on the deck or on a bulkhead. Consider the following points when selecting a mounting location.

???Select a location which is both well ventilated and low in humidity to keep the unit cool.

???For bulkhead mounting, be sure the mounting location is strong enough to support the weight under the continued vibration normally encountered on the vessel.

???A magnetic compass will be affected if the distribution box is too close. Observe the compass safe distances to prevent disturbance to the magnetic compass.

1.Screw in lower hex. bolts so there is 5 mm clearance between bottom of screw head and bulk- head.

2.Hang the unit on the bolts, then tighten the bolts.

3.Fasten the unit with upper hex. bolts.

1.4Transducer

The performance of this equipment is directly dependent on the installation of the transducer.

The installation of the transducer and the tank must be accomplished by a dockyard referring to the installation drawings at the later part of this manual.

1.4.1Installation location

To decide the location of the transducer, the following points must be taken into account.

??? Locate the transducer of DS-60 at least 2.5 m from the transducer of an echo sounder.

DOPPLER SONAR TRANSDUCER

2500 mm or more

???Separate as far as possible from air bubble sources; e.g., side thruster and water disposal pipes.

???Install in close proximity to the keel, for uniform water flow.

???Generally, best performance is obtained by mounting on the bow; the stern side is influenced more easily by air bubbles and propeller cavitation.

???Do not apply any paint to the transducer face.

APPENDIX 1 CALIBRATION

Milepost run

It is common practice to check a new ship???s performance at an official trial run. Take this op- portunity to calibrate the DS-60. In practice, the ship speed is evaluated as follows.

1. Calculation with transit posts

Steer the ship at a steady speed on the test course, e.g. A???B in the illustration. Speed is ob- tained from the following equations. Note that Sg1 and Sg2 are both speeds over the ground (SOG); however the DS-60 provides the speed through the water. To find the speed through the water, a return trip is necessary.

Sg1

Sg2

AB

Sg1 = d/t1 X 3600 (kn)... (1) Sg2 = d/t2 X 3600 (kn)... (2) Sw + St = Sg1 (kn)... (kn3)

Sw - St = Sg2 (kn)... (4) Adding (4) and (3), we get; 2Sw = Sg1 + Sg2 (kn)

Therefore, Sw = (Sg1 + Sg2)/2 (kn)... (5) where,

d = distance run (nm),

t1 = time taken to run 1 (second),

t2 = time taken to run 2 (second). (Note: Runs 1 and 2 are in opposite direction.) Sw = Speed through the water (kn),

St. = Speed of tide current (kn), Sg1 = SOG for run 1 (kn),

Sg2 = SOG for run 2 (kn).

Thus we can find a speed through the water by making a round tip.

AP-1

APPENDIX

2. Calculation with DS-60

To measure the distance run between points A and B by DS-60, do the following:

1.Reset the distance run figure of DS-60 to zero by selecting Reset on the Trip DIST menu at the moment the ship passes point A.

2.Run the ship from A to B at full speed, timing with a stopwatch.

3.Read the distance run (nm) and time taken to run (second) exactly at the moment the shipshape point B.

4.Run the ship from B to A at full speed rehearing to step 1 through 3.

Where,

n1 (nm) = distance run from A to B measured by DS-60 n2 (nm) = distance run from B or A measured by DS-60

Therefore, the average run from A to B measured by DS-60

Therefore, the average ship speeds of run 1 and run 2 are calculated as follows.

Slog1 (kn) = n1/t1 X 3600

Slog2 (kn) = n2/t1 X3600

The average ship speed of round trip is Slog (kn) = (Slog1 + Slog2)/2 ...(6)

3. Speedily error

From (5) and (6),

Error = (Sw - Slog)/Slog X 100 (%)... (7)

This error can be corrected at SPEED OFFSET on the system menu as follows:

1.Press the [MENU/ESC] key.

2.Select SYSTEM MENU and press the [ENT] key.

3.Select SPEED OFFSET and press the [ENT] key.

4.Enter the value of error.

Repeat the above procedure several times to satisfy the speed accuracy specification.

APPENDIX 2 JIS CABLE GUIDE

Cables listed in the manual are usually shown as Japanese Industrial Standard (JIS). Use the following guide to locate an equivalent cable locally.

JIS cable names may have up to 6 alphabetical characters, followed by a dash and a numerical value (example: DPYC-2.5). For core types D and T, the numerical designation indicates the cross-sectional Area (mm2) of the core wire(s) in the cable. For core types M and TT, the numerical designation indicates the number of core wires in the cable.
