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.

•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, 2.15 m, Steering compass, 1.60 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

Installation precaution for S-band scanner unit

If an S-band scanner unit is mounted near the end of a platform to provide sufficient rotation clearance for the radiator, the scanner unit, because of its weight, swings up and down by ship’s vibration and rolling, exerting excessive levels of stress at the base of the radiator, which can damage the radiator. To prevent this, relocate the scanner unit, or if relocation is not possible, reinforce the platform.

Pole for DF, etc.

Remarkable vibration (pitching)

Mounting position

EXAMPLE

Pole for DF

Mount the scanner unit Directly on the mast or on the platform, as near as possible to the center of the mast.

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.

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

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 bracket with a waveguide clamp, a clamp insulator, two flat washers, and two M6x50 hex bolts.

5.Grease other O-ring and set it in the groove of the radiator flange.

6.Set the scanner radiator to the bracket and fix it temporarily with eight M10x20 hex bolts, spring washers and flat washers.

7.Fasten the feeder waveguide to the radiator flange with four M6x16 hex bolls.

8.Fasten the scanner radiator to the bracket with eight M10x20 bolts.

1.2 Display Unit

Before mounting the display unit

If Gyro Converter GC-8 (option) is to be used, install and setup the GYRO CON-

VERTER 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 supply cable between the display unit and the 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.

6.Ground the armor through the two washers as shown above. Trim the shields considering their location on the earth terminal inside the scanner unit. Fit a crimp-on lug (yellow, FV5.5-4, ø4) to inner and outer shields, then connect them to the ground terminal inside the scanner unit.

7.Determine the length of each core considering its location on STB-1 in the scanner unit (see the interconnection diagram on page S-1). Remove approx. 6 mm of the vinyl insulation from the end of each core and fix the crimp-on lug FV1.25-M3 (Red) to each core.

8.Remove the outer sheath of the coaxial cable (2C-2V) by 75 mm. Pull back the braided shield to expose the inner core. Remove approx. 25 mm of insulator from the end of inner core and fold back conductor as illustrated below. Shorten the shield leaving approx. 45 mm. Fit crimp-on lugs to the conductor (FVD1.25- 3, Red) and braided shield (FV1.25-M3, Red).

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 deicer. (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.)
