1.1 Scanner Unit

Mounting considerations

• The scanner unit is generally installed either on top of the wheelhouse or on the radar mast, on a suitable platform. Locate the scanner unit where there is a good all-round view.

• No funnel, mast or derrick should be within the vertical beamwidth of the scanner in the bow direction, especially zero degrees ±5°, to prevent blind sectors and false echoes on the radar picture.

• It is rarely possible to place the scanner unit where a completely clear view in all directions is available. Thus, you should determine the angular width and relative bearing of any shadow sectors for their influence on the radar at the first opportunity after fitting.

• Locate the antenna of a direction finder clear of the scanner unit to prevent interference to the direction finder. A separation of more than two meters is recommended.

MOUNTING

• T o lessen the chance of picking up electrical interference, avoid where possible routing the signal cable near other onboard electrical equipment. Also avoid running the cable in parallel with power cables.

• A magnetic compass will be affected if placed too close to the scanner unit. Observe the following minimum compass safe distances to prevent deviation of a magnetic compass: Standard compass, 3.90 m, Steering compass, 2.30 m.

• Do not paint the radiator aperture, to ensure proper emission of the radar waves.

• The signal cable run between the scanner and the display is available in lengths of 15 m (standard), 20 m, 30 m and 60 m. Whatever length is used it must be unbroken; namely, no splicing allowed.

• Deposits and fumes from a funnel or other exhaust vent can adversely affect the aerial performance and hot gases may distort the radiator portion. The scanner unit must not be mounted where the temperature is more than 70°C.

• The scanner base is made of cast aluminum. To prevent electrolytic corrosion of the scanner base, use the seal washers and corrosion-proof rubber mat and ground the unit with the ground wire (supplied).

• Leave sufficient space around the unit for maintenance and servicing. See the scanner unit outline drawing for recommended maintenance space.

1-1

• The scanner unit is normally mounted with the gland side (cable entry side) facing the ship’s stern. If this direction is not possible, the gland orientation can be changed in increments of 90°. In this case, the synchronous gear magnet, which produces the heading signal, should be remounted. Fix the magnet according to scanner unit orientation.

Scanner unit assembling

The scanner radiator and the scanner housing are shipped in separate packages and must be assembled at installation. Assemble them as below. Refer to the scanner unit assembling drawing at the back of this manual for details.

1. Remove two protective caps from the radiator flange and rotary joint flange.

2. Grease an O-ring and place it in the groove of the rotary joint flange. Make sure the O-ring is not pinched during assembling.

3. Secure the feeder waveguide to the rotary joint flange with four M6x16 hex bolts.

4. Fix the feeder waveguide on the radiator joint with four M4x16 washer head bolts. Coat waveguide flange with silicone sealant as illustrated below.

Apply silicone sealant here.

Apply silicone sealant here.

Evenly coat the waveguide flange with silicone sealant. Apply sealant sparingly; it leaks out slightly when the fixing bolts are tightened. Be sure no sealant contacts the choke groove and waveguide.

Figure 1-2 How to coat waveguide flange with silicone sealant

5. Loosely fix the radiator to the radiator bracket with M8x25 and M8x30 hex head bolts, M8 flat washers, M8 spring washers, and M8 hex nuts.

6. Grease the other O-ring and place it in the groove of the radiator flange. Secure the feeder waveguide to the radiator flange with M4x16 washer head bolts.

7. Fix the feeder waveguide to the bottom of the radiator with the waveguide clamp, waveguide packing, M4x30 hex head bolts, M4 flat washers, and M4 spring washers.

8. Tighten bolts loosely fixed at step 5.

1-3

Scanner unit mounting

The scanner unit should be assembled before hoisting it to the mounting platform. When using a crane or hoist, lift the unit by the hoist rings which should be fastened to the bolt fixing covers of the scanner housing. Do not lift it by the scanner radiator.

CAUTION

DO NOT lift the scanner unit by the radiator; lift it by the hoist rings. (Be sure to remove rings after lifting the scanner.)

Hoist ring

NO!

1. Construct a suitable mounting platform referring to the outline drawing at the back of the manual.

2. Drill four mounting holes of 15 mm diameter and one cable entry hole of about 50 mm diameter in the mounting platform.

3. Lay the rubber mat (supplied) on the mounting platform.

4. Place the scanner unit on the rubber mat orienting the unit so the bow mark on its base is facing the ship’s bow.

5. Fasten the scanner unit to the mounting platform with M12x60 hex bolts, nuts, flat washers and seal washers.

6. Using hex bolt (M6x25), nut (M6) and flat washer (M6) establish the ground system on the mounting platform as shown in Figure 1-3. Connect the ground wire (RW-4747, 340 mm, supplied) between the grounding point and ground terminal on the scanner unit. Coat the entire ground system with silicone sealant (supplied).

1.2 Display Unit

Before mounting the display unit

If Gyro Converter GC-8 (option) is to be used, install and setup the GYRO CONVERTER Board before mounting the display unit, because of the difficulty involved in doing it after the display unit is installed. Instructions for installation and setup are in Chapter 4.

Mounting considerations

When selecting a mounting location, keep in mind the following points:

• Select a location where the display unit can be viewed and operated conveniently and where the screen can be viewed while facing towards the bow.

• Locate the unit out of direct sunlight and away from heat sources because of heat that can build up inside the cabinet.

• Locate the equipment away from places subject to water splash and rain.

• The display unit is very heavy. Be sure the mounting location is strong enough

to support the weight of the unit under the continued vibration which is normally experienced on the ship. If necessary reinforce the mounting location.

• Determine the mounting location considering the length of the signal cable between the scanner unit and the display unit and the power cable between the display unit and Power Supply Unit PSU-004.

• Leave sufficient space on the sides and rear of the unit to facilitate maintenance. Also, leave a foot or so of “service loop” in cables behind the unit so it can be pulled forward for servicing or easy removal of connectors.

• A magnetic compass will be affected if placed too close to the display unit. Observe the following compass safe distances to prevent deviation of a magnetic compass: Standard compass, 1.70 m, Steering compass, 0.90 m.

Mounting procedure

8. Connect the conductors to STB-2 and STB-3, referring to the interconnection diagram on page S-1.

9. Check for loose screws, poor contact on crimp-on lugs, etc. Close the terminal boards.

When the de-icer is installed

1) Before beginning any work on the scanner unit, turn off the breaker for the deicer line at the main switchboard to remove the power (100 VAC, 1ø) to the de-icer. (Turning off the power to the display unit has no effect.)

2) The neck of the scanner unit becomes VERY HOT when the de-icer is working. (The de-icer turns on when ambient temperature is below 0°C.)

Fixing the scanner cover

Before closing the cover check for loose screws and poor contact on crimp-on lugs. Grease fixing bolts for cover, gasket and tap holes in scanner chassis. Attach cover .
