1. MOUNTING

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.

(a) On bridge

(b) Common mast

(c) Radar mast

Figure 1-1 Mounting methods

•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.

•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 scanner unit. Observe the following compass safe distances to prevent deviation of a magnetic compass: Standard compass,1.70 m (FR-2815), 2.10 m (FR-2825), Steering compass, 1.90 m (FR-2815), 1.20 m (FR-2825).

•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, and 30 m. Whatever length is used it must be unbroken; namely, no splicing allowed.

•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).

•Deposits and fumes from a funnel or other exhaust vent can adversely affect the aerial per-

formance and hot gases may distort the radiator portion. The scanner 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 scanner unit outline drawing for recommended maintenance space.

1 - 1

Assembling the scanner unit

The scanner unit consists of the scanner radiator and the scanner unit chassis, and they are packed separately. Fasten the scanner radiator to the scanner unit chassis as follows:

1)For the XN20AF, XN24AF, attach two guide pins to the underside of the scanner 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 1-2.

Hole for	Hole for
a guide pin	a guide pin

Anticorrosive sealant

Figure 1-2 Coating the waveguide flange with anticorrosive sealant

4)Coat fixing holes for the scanner radiator with anticorrosive sealant.

5)Grease the O-ring and set it to the O-ring groove of the radiator flange.

6)Set the scanner radiator to the radiator bracket.

7)For the XN20AF, XN24AF, coat hex bolts (M8 x 40, slotted washer head, 8pcs.) with anticorrosive sealant and use them to loosely fasten the scanner radiator to the scanner unit chassis. For the XN12AF, coat hex bolts, flat washers and spring washers with anticorrosive sealant and use them to loosely fasten the scanner radiator to the scanner unit chassis.

8)Remove two guide pins (inserted at step 1), and then tighten fixing bolts.

CAUTION

Be sure to remove the guide pins.

Injury may result if the guide pins loosen and fall.

Fastening the scanner unit to the mounting platform

The scanner unit may be assembled before hoisting it to the mounting platform. However, do not lift the scanner unit by the radiator. Always hold the unit by its housing. 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.

CAUTION

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

Hoist		NO!
ring

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.

1 - 3

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 1-5. The location should be within 370 mm of the ground terminal on the scanner unit. Connect the ground wire (RW-4747, 370 mm, supplied) between the grounding point and ground terminal on the scanner unit. Coat the entire ground system with silicone sealant (supplied).

1.2 Mounting the Display Unit

The display unit is designed to be mounted on a tabletop or on a pedestal (option).

Before mounting the display unit

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

Siting considerations

Locate the display unit on the bridge in a place where it can be viewed and operated conveniently. In addition, consider the points noted in the figure which follows.

CAUTION

A magnetic compass will be affected if placed too close to the display unit. The minimum compass safe distances for magnetic compasses are

standard compass:1.6 m steering compass: 1.2 m

Consider the points mentioned below when selecting a mounting location for the display unit.

•The orientation of the display unit should be so the operator views the screen while facing the bow. This makes determination of position much easier.

•The location should be free of water spray.

•The daylight bright type radar display

provides excellent visibility even in direct sunlight. However, locate the unit out of direct sunlight and away from heat sources because of heat that can build up inside the cabinet.

•The mounting location should be determined considering the length of the signal cable between the antenna unit and the display unit. (The signal cable comes in lengths of 15, 20 or 30 meters; maximum 100 meters.)

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

Mounting procedure

Tabletop

1)Unfasten the three M10 bolts at the front of the display unit and separate the mounting base from the display unit.

2) Drill five holes of 12mm diameter in the tabletop.

3)Secure the mounting base to the tabletop by using M10 nuts, bolts and flat washers.

4)Place the display unit on the mounting base and fasten it to the mounting base with the bolts removed in step 1.

Pedestal

Fix the pedestal to the mounting location with M12 nuts, bolts and washers. (The cable gland is at the bottom of the pedestal.) See the outline drawing at the back of this manual.
