SECTION ONE: Introducing the Northstar radar

WARNING!

Microwave Radiation Hazard

The microwave energy radiated by a radar antenna is harmful to humans, especially to one’s eyes. Never look directly into an open waveguide or into the path of radiation from an enclosed antenna. Radar and other radio frequency radiation can upset cardiac pacemakers. If someone with a cardiac pacemaker suspects abnormal operation, immediately turn off the equipment and move the person away from the antenna. Turn off the radar whenever it is necessary to work on the antenna unit or on other equipment in the beam of the radar.

High Voltage Warning

Dangerously high voltages are present within the radar scanner unit. There are no internal connections or adjustments necessary for installation. The cover should be removed only by a qualified radar service technician. Technicians must exercise extreme care when working inside the unit. Always remove power before removing the cover. Some capacitors may take several minutes to discharge, even after switching off the radar. Before touching the magnetron or any high voltage components, ground them with a clip lead.

The Northstar R2D radar is designed as an option available for the Northstar 6000i navigator.

A radar unit should only be installed by a qualiﬁed marine technician, as potentially lethal high voltage is present, along with heavy rotating parts. There is a transmit interlock that prevents radar transmissions if the array is not rotating. However, high voltage remains for a period of time after the system is turned off. If you are not familiar with this type of electronics, consult with a trained service or installation technician before attempting to service any part of the equipment.

Installation includes mechanical mounting and electrical wiring, followed by properly conﬁguring the navigator to work with the radar, and ﬁnally adjusting the radar for proper performance.

Don’t take any shortcuts, and follow these instructions carefully.

NOTE:

For the radar overlay to function properly on the chart screen, you must correctly navigator’s NMEA interface connector, pins 1 and 3). Without the heading sensor, the radar image will not line up properly with the chart.

The Northstar 6000i accepts the following standard NMEA 0183 sentences to obtain heading information from a sensor: HDG, HDT, OSD, HCC, HCD, and HDM.

For sensor installation and calibration instructions, see the sensor manufacturer’s installation manual. In addition, the navigator must be calibrated to the heading sensor as described on page 17

Installing the antenna

CAUTION!

To eliminate interference, install the antenna away from GPS and radio receiver antennas, including SatNav and satellite TV antennas.

Choosing the antenna location

The radar’s ability to detect targets depends greatly on the position of its antenna. The ideal antenna location is high above the ship's keel line where there aren’t any obstacles. This ideal location is limited by various factors; therefore, consider the following when choosing the antenna location:

•

install the antenna as high as possible (after considering the structure of the vessel’s hull, the weight of the antenna, and how easy it will be to maintain the antenna). The higher the installation position, the longer the radar ranging distance.

•

install the antenna away from masts or other obstructions. If the antenna isn’t higher than obstructions, radar waves may be blocked, creating shadow zones or generating false echoes.

•

install the antenna closer to the vessel’s bow, for a clear view to the front. When installing the antenna on a mast, place it in front of the mast. If obstacles can’t be avoided for vessel structural reasons, see “Shifting the antenna away from the keel line,” described below.

•

install the antenna as far away as possible from the antennas of other equipment, such as direction ﬁnders, GPS equipment, radio receivers, etc. Radar scanners may cause interference with radio receivers.

•

keep the connecting cable as short as possible. Whenever possible, keep the distance from the antenna to the navigator within the standard cable length of 10 meters. If you must use longer cable, do not exceed 30 meters.

•

Don’t install the antenna where it may be subjected to smoke or hot air from smokestacks

or heat from lamps.

Shifting the antenna away from the keel line

By shifting the antenna position from the keel line to starboard, it’s possible to move shadow zones to the port side. This makes it possible to keep a clear view to the bow. You can calculate the distance to be shifted, depending on the distance from the antenna to any obstacles, by using the following equation (Ls = distance to be shifted from keel line; D = diameter of obstacle on keel line; and R = distance from antenna to obstacle):

Ls=0.4R+D/2 (when R<15m)

Ls=0.025R+D/2 (when R>=15m)

SECTION TWO: Installing and wiring the radar

Figure 2: Shifting from the keel

Obtaining sufﬁcient dip angle

Raise the antenna position above on-board obstacles to avoid shadow zones. Dip angle is the angle between a horizontal line and the line of sight from the antenna to the obstacle. By maintaining a dip angle greater than 5 degrees, you may be able to prevent mid- and long-distance shadow zones. The radar can’t detect objects below its line of sight.

Figure 3: Sufﬁcient dip angle

Mounting the antenna

It may be easier to install the antenna by fabricating a mounting base, as shown below, but you can also install the antenna directly to a rigid, ﬂat surface, such as the roof. Pay attention to the water drain tube at the bottom of the antenna.

Figure 4: Using a mounting base

R2D Radar Installation Manual, Rev. A Page 5

SECTION TWO: Installing and wiring the radar

NOTE:

When the radar platform or mounting bracket has a curvature of more than 2mm, repair it or use spacers.

1. Referring to Figure 5 below and the supplied full-size antenna mounting templates, drill four 1/2 in. (13mm) diameter holes through the mounting surface.

2. Check that each bolt (with lock washer and ﬂat washer) protrudes at least 5/15 in. (8mm) but less than 9/16 in. (15mm). The scanner will be damaged if bolts protrude more than 9/16 in. (15 mm).

3. Apply sealant around each mounting hole.

4. Place the radome scanner unit on the mounting surface. Orient the radome with the index mark on the housing facing forward (cable gland facing aft).

5. Install and tighten four M10 X 25U (M10 X 1 in.) mounting bolts

6. Secure the cable near the scanner to support the weight of the cable and prevent strain on the watertight cable seal.

The bolts supplied will sufﬁce for mounting base thicknesses of 3/16 to 3/8 inch (5 to 10 mm). If the mounting base is thicker or thinner than that, use bolts speciﬁed in Table 2 on page 7. See Figure 6

below for details on bolting the antenna to the mounting base.

Replacing the fuse

You must use proper rating fuses to safely operate the radar. Replace the internal fuse with a 5A 125V fuse only.

Wiring the radar

Regardless of the type of antenna, when connecting the cables, keep in mind the following:

•

Do not tie the radar cables, especially the power supply cable, together with the cables of

other equipment

•

leave service and drip loops so you can easily remove the control box

•

mount the control box in a dry area protected from moisture and humidity

•

lay the cable along the vessel’s hull or wall surface, and secure it at intervals of about

16” (40 centimeters)

Install the radar antenna cable as described below.
