1. MOUNTING

1.1 Antenna Unit

1.1.1 Mounting considerations

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

• No funnel, mast or derrick should be within the vertical beamwidth of the antenna 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 antenna 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 antenna unit to prevent interference to the direction finder. A separation of more than two meters is recommended.

• To 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 antenna unit. Observe the following compass safe distances to prevent deviation of a magnetic compass: Standard compass, 1.70 m (FR-2115-B), 2.10 m (FR-2125-B), Steering compass, 0.90 m (FR-2115-B),

1.20 m (FR-2125-B).

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

• The signal cable run between the antenna and the display is available in lengths of 15 m

(standard), 20 m, and 30 m. Whatever length is used it must be unbroken; namely, no splicing allowed.

• The antenna base is made of cast aluminum. To prevent electrolytic corrosion of the antenna base, use the seal washers and corrosion-proof rubber mat.

• 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 antenna unit must not be mounted where the temperature is more than 70°C.

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

1-1

1.1.2 Assembling the antenna unit

The antenna unit consists of the antenna radiator and the antenna unit chassis, and they are

packed separately. Fasten the antenna radiator to the antenna unit chassis as follows:

1. For the XN20AF, XN24AF, attach two guide pins to the underside of the antenna radiator.

2. Remove the waveguide cap from the radiator bracket. The cap may be discarded.

3. Coat the waveguide flange with anticorrosive sealant as shown in Figure 1-1.

2.1.2 Fabricating signal cable S03-75

1. Remove the vinyl sheath by 450 mm.

2. Slide the clamping ring, washer, rubber gasket and washer onto the signal cable in that order.

3. Unravel the outer shield to expose the cores in the outer layer. Then, unravel the inner shield to expose the cores in the inner layer. Label all inner cores to aid in identification.

4. Attach EMI cores to all inner cores and all outer cores, and bind them with cable ties, etc. Note that there are two types of the EMI cores, thick and thin.

5. Trim each core (except coaxial wire) considering its location on the terminal board in the antenna unit.

6. Trim the inner and outer shields leaving 500 mm each. Twist shields together and attach crimp-on lug FV5.5-4 (blue, φ4).

2.2 Processor Unit

Two cables are terminated at the processor unit: the signal cable S03-75 and the power cable. The signal cable comes with a connector preattached to it for connection to the processor unit. Fabricate the power cable as below.

2.2.1 Fabricating the AC power cable

1. Remove the vinyl sheath by 80 mm. Cut off jute tape wrapped around the armor. Unravel the armor to expose the cores by about 35 mm.

2. Remove insulation of cores by about 10 mm. Fix crimp-on lugs to the cores and armor.

3. Cover the armor with vinyl tape, leaving the portion which will lie inside the cable clamp untaped.

2.3 Monitor

2.3.1 Connection of monitor cable inside processor unit

The monitor cable (a monitor cable comes with FURUNO-supplied monitor) runs between the

RGB Board (inside the processor unit) and the monitor. Route it inside the processor unit as

below. Connect the cable to J2 on the RGB Board. If a converter adaptor is used it may be

necessary to route the cable differently than shown. In any case be sure the cable does not

touch the TX-HV Board.
