SECTION 3 INSTALLATION

This section provides practical guidelines to assist in the planning and installation of the RADAR 3000 aboard your vessel.

3.1

UNPACKING AND INSPECTION

Use care when unpacking the RADAR 3000 radar from the shipping carton to prevent damage to the contents. It is also good practice to save the carton and the interior packing material until the radar has been satisfactorily installed on the vessel. The original packing material should be used in the unlikely event that it is necessary to return the unit for service.

3.2

PLANNING THE INSTALLATION

The layout for installing the RADAR 3000 should be planned to give the best operation and service aboard your particular vessel. In general, the scanner unit should be mounted as high as possible above the waterline. The display unit should be installed in a convenient viewing position near the helm. Keep in mind the optimum viewing angle when installing the display. You may want to apply power in advance of installing the unit as that you can determine a satisfactory viewing angle.

A 10 meter length of interunit cable is furnished for interconnecting the two main units (scanner and display). This length of interunit cable should be sufficient to complete the cable run required on most small vessels. It is recommended that the maximum length of interunit cable not exceed 20 meters.

A general system diagram for the RADAR 3000 is shown on the following page.

MOUNTING THE DISPLAY UNIT

When planning the installation for your display unit, the following conditions should be considered to ensure dependable and trouble free operation.

1) The mounting location should be easily accessible to allow operation of the front panel controls.

2) There should be adequate ventilation.

3) There should be sufficient space behind the display unit to allow cable connections to the rear panel connectors.

4) The display unit should be located near a DC power source.

5) The selected location should be far enough away from device that may cause interference, such as motors and generators.

6) Generally, the display unit should be located in a protected area away from prolonged direct exposure to rain and salt spray. It is good practice to protect your valuable electronic equipment as much as possible.

The display unit can be conveniently mounted on a chart table, or bulkhead mounted in a desired location. Using the outline of FIG 3-1 and 3-2 as a guide, install the display unit and secure to the mounting surface.

3.4

MOUNTING THE SCANNER UNIT

Selecting an adequate location for the scanner unit requires careful consideration. On many small vessels, the unit can be installed on a mast platform, on an arch, or on a bridge structure near the ship’s centerline.

The radiator beam should not be obstructed by nearby large objects. Locate the unit where large structures such as superstructures, searchlight, horns or masts are not in the same horizontal plane, otherwise, blind areas and false targets can appear on the radar screen.

Using the outline drawing of FIG 3-3 or template in the front of the manual as a guide, install the scanner unit and secure it to a solid mounting surface.

Usually the mounting surface for the scanner unit should be parallel with the ship’s waterline. Some vessels, however, may adopt a higher bow angle when the vessel is at its cruising speed. This substantially alters and raises the radar’s radiation plain. In this case nearby target detection might be poor. It may be helpful to lower the radar beam towards the parallel by shimming the radar pedestal so as to tilt the beam angle slightly downward with respect to the waterline.

3.5

CONNECTING THE SCANNER UNIT CABLE

① Route the scanner unit cable from bottom of the mounting base and connect them to connectors J1 and W1 of the CME-229 modulator printed circuit board.

② Tighten the ground terminal and securing the clamping plate with the rubber grommet.

ELECTRICAL CONNECTION

3.6.1 DC POWER CABLE

The RADAR 3000 will work with any ship’s mains within the 10.2 to 42 V range, since it contains a power regulator circuit. Connect the power cable to a

DC source. The power cable normally should be wired through the circuit breaker.

The white lead wire of the power cable should be connected to the positive source terminal and the black lead to negative source terminal. The shielded wire should be connected to the ship’s RF ground. Should the power connections be inadvertently reversed, a protective fuse will blow. Recheck the input power leads for correct polarity with a VOM and reconnect the leads observing correct polarity. Replace the fuse.

3.6.2 EXTERNAL SYSTEM INTERFACE

CAUTION

To connect with NAV-AID and/or compass, make sure pin assignment, if used same connector.

In case of different pin assignment, the RADAR 3000 or connected NAV-AID will be damaged.

4.28 DISPLAY OF RADAR TRANSPONDER

SART (Search and Rescur Radar Transponder) is life preserving device approved by GMDSS which is used for locating survivors in the event of a disaster or distress. SART operates in the 9 GHz frequency band. When it receives a radar signal (interrogating radio wave) of 9 GHz transmitted by a rescue ship or aircraft radar, SART transmits a series of respouse signals to the searchers to indicate the distress position.

In order to see the SART or radar beacon mark on the radar screen.

① RANGE SCALE : Select 6 or 12 nm.

② SEA : Set to minimum.

③ TUNE

④ IR

: DETUNED to reduce the clutter.

: Set IR OFF.

Attention

When above settings ① to ④ are made to display SART signals, objects around the own ship will not appear on the radar screen, so perform thorough visual monitoring of the sea area around the own ship to avoid any collision or stranding.

Further, when more than one radar systems are mounted, while using a 9 GHz band radar for searching SART signals, be sure to use another radar as an ordinary radar to perform monitoring of objects around the own ship to avoid any collision, check of the position of the own ship to avoid any stranding, and so on.

SECTION 5 MAINTENANCE

The purpose of this section is to provide servicing instructions for the service technician. The RADAR 3000 is designed to provide long periods of trouble free operation. However, environmental and other factors may required this equipment to be serviced.

WARNING

This radar equipment contains high voltage. Adjustments require specialized service procedures and tools only available to qualified service technicians. There are no user serviceable parts or adjustments. The operator should never remove the radar unit cover nor attempt to service this equipment. When servicing this equipment, it is important that the technician comply with all safety precautions set forth in this manual.

The high voltage can cause a severe personal injury by the electric shock.

5.1

PREVENTIVE MAINTENANCE

Continuous satisfactory operation of the radar can depend on how well it is treated. The following maintenance tips can save you time and money, and will help avoid premature equipment failure.

1. Always keep the equipment as clean as possible. Remove dirt, dust, or water-spray from the display and scanner during the boat clean up. These units are “water resistant” but not “water proof”. Do not immerse.

2. During routine ship’s maintenance, inspect the radar system for the following points:

(1) Check all hardware for tightness.

38 MAINTENANCE

(2) Check for evidence of any corrosion of the scanner unit, display unit, or its cable and connectors. Clean as required.

(3) Check that the cable connector is secure.

5.2

CLEANING THE SCANNER UNIT

Wash the exterior of the scanner unit with fresh water. But do not immerse the unit. A heavy deposit of dirt or caked salt on the surface of the scanner may cause a considerable drop in the radar performance. Clean the face of the display unit with a clean, soft, lint-free cloth slightly dampened with fresh water.

5.3

CLEANING THE DISPLAY SCREEN

Dust on the screen tube will reduce the grass transparency and make the video image dim. Wipe the screen surface with a soft lint-free cloth (made of flannel or cotton). A cloth moistened with an antistatic agent will not cause a problem.

When using it, wipe softly; never rub the screen surface with excessive force.

(2) Check for evidence of any corrosion of the scanner unit, display unit, or its cable and connectors. Clean as required.

(3) Check that the cable connector is secure.
