1. INSTALATION OVERVIEW
The Doppler Sonar Current Indicator CI-88 consist of a monitor unit (not available for black
box type), a transceiver unit, junction box and transducer (hull unit). To obtain absolute tide
even in deep waters, the CI-88 must be supplied with speed/course data (or position data)
from navigation equipment (GPS) and heading data from a gyrocompass (via an A-D
converter). The equipment can output ship’s speed and true bearing data to a radar or
scanning sonar for true-motion display. Further, current data can be output to an echo
sounder or scanning sonar in CIF format.
To obtain full performance from the equipment, the installation of the units, especially the
hull unit, is very important. Poor siting of units or poor cable layout may cause pick-up of
noise, or give interference to other units. This chapter presents an overview of how to install
the equipment.
1.1 Selection of Installation Site for Transducer
The performance of the equipment largely depends on the installation of the transducer unit,
and a very important consideration is the installation site. Is should meet the following
requirements.
a) No projections (such as sonar’s retraction tank) should exist in the hatched area shown
below. However, when the transducer projects below the lowest part of the keel, the
effects when the sonar transducer is lowered must be taken into account.

b) Mount the transducer at a location between one-third and one-half of the ship’s full
length (measuring from the bow). Select a place where the transducer is free from the
effects of air bubbles. The transducer face should not be above the sea surface when
the ship is pitching or rolling.
c) In general, the air bubbles produced at the bow flow backward alongside the keel.
Therefore, separate the transducer by more than 1000 mm from the keel, or flush mount
the transducer inside the keel.
d) The surface of the transducer should project by 250 mm or more from the hull bottom.
For better performance, its surface should be even with the keel’s lowest point or below
it.
e) The following is important for preventing interference between the CI-88 and other
equipment.
If the transducer of an echo sounder or scanning sonar whose harmonic is within the
frequency range of 236 kHz to 252 kHz (244 ±8 kHz) is mounted, interference may
occur. Even if the harmonic is out of the range, the risk of interference still exists if the
transducer of the CI-88 and other equipment are mounted near one another. For this
reason, separate the transducer of the CI-88 as far as practical from other equipment
which have high output power. If interference is unavoidable due to limited mounting
space, connect the interfering equipment tothe built-in interference rejection circuit (two
inputs) in the transceiver unit. For connection to this circuit, you will need to run a
two-core cable between it and the interfering equipment.
f) Make the transducer cable as short as possible. The cable is generally installed in
grounded steel conduit run between the transducer and the junction box, to prevent
pick-up of noise. The transducer with the 20 m transducer cable can be used only when
it is passed inside conduit.
Do not transport the transducer by pulling the cable.
The internal wiring may be cut.
NOTE

1. INSTALATION OVERVIEW

WARNING
If a steel tank is installed on an FRP vessel,
take appropriate measurements to prevent electrolytic
corrosion.
Electrolytic corrosion can damage the hull.
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.
The tank or hull may be damaged if the tank strikes an
object.
1.2 Ground
This equipment uses pulse signals which may cause interference to other electronic
equipment such as a direction finder and radio receiver, if it is not grounded properly. It is
strongly recommended to ground all cables referring to the guidelines below.
a) Separate all units as far as possible from radio equipment.
b) Do not run interconnection cables close to or near radio equipment or its cables.
c) Run the cables in the shortest path practical.
d) Lay the cables on grounded copper plate and fix themevery300 mm withmetal cable
clamps.
e) Ground all units as shown in the figure below and on the next page.
f) To join copper straps, use solder cream for perfect contact.

2.2 Transceiver Unit
Mounting 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 50 mm
clearance between it and the floor to permit dissipation of heat.
• This unit weights 12 kg. 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.
Mounting procedure
1. Weld the steel plate (shipyard supply) with four mounting holes to the bulkhead.
2. Use four bolts and nuts (M10, supplied as installation material) to fix the transceiver unit
to the steel plate described at step 1.

2.3 Junction Box (option)
Mounting considerations
The junction box forms a joint between the transducer and the transceiver unit. Install it
referring to the guidelines below.
• Keep the junction box away from noise-emitting electrical machinery, i.e., electric
generator, radio transmitter, TV, etc.
• Although the box is splashproof, do not install it in places of high humidity.
• Avoid installing the box where temperature varies greatly, since moisture may penetrate
the box.
• The box is generally installed above the draft line of the ship and the transducer cable is
run inside steel conduit. This permits replacement of the transducer without dry docking.
• Even if the junction box is installed below the draft line, the conduit is necessary to avoid
picking up noise. If use of conduit is not possible, install the box as near to the transducer
as possible.

2.4 Transducer (Hull Unit)
Mounting location
See Chapter 1.
Do not transport the transducer by pulling the cable.
The internal wiring may be cut.
NOTE
2.4.1 Hull mounting
Mounting the transducer for steel hull vessels
1. Select a mounting place on the hull bottom. (Since the transducer cable is comparatively
thick, select a mounting place for the thru-hull pipe where the cable can be easily led
into the cable gland.).
2. If necessary, weld a double plate (shipyard supply) to the hull bottom to reinforce the
hull.
3. Unpack the transducer casing and determine the projecting length, making it 250 mm or
more. Before cutting the casing, note that the transducer casing has “fore-aft direction.”
Then, cut it considering the rising angle of the ship’s hull.
Weld the casing in parallel with ship’s fore-aft line with an accuracy of better than ±1°.
The transducer face should be horizontal at cruising speed.

Dimple to bow
Transducer fixing flange
4. Make a hole for the thru-hull pipe in the hull bottom. Before welding the thru-hull pipe,
remove the rubber packing from the thru-hull pipe. Weld the thru-hull pipe. Replace the
rubber gasket.
5. Make a hole of 10 to 20 mm diameter on the stern side of the casing to allow water to
penetrate the transducer casing.
6. Weld the casing to the hull bottom. Do not remove the transducer fixing flange to
prevent the casing from being deformed.
7. Dismount the fixing flange from the casing. Fix the transducer to the fixing flange.
8. Pass the transducer cable through the thru-hull pipe. Tighten the cable gland, leaving
0.5 to 1 m of slack in the cable below the cable gland.
