Only qualified personnel should install or service this equipment. Installation or servicing work that is done by non-qualified personnel can result in equipment breakdown, poor performance of the equipment, fire, electrical and physical hazards, injury or death. Wear safety equipment such as a hard hat and a safety belt at all times when installing or working on the scanner. The scanner is usually installed in an elevated position and serious injury or death can result if a person fall

3 Introduction to the Northstar radar The Northstar radars are designed as an option available to the Northstar 6000i, 6100i, or 8000i systems. A variety of scanner models are available (2 kW, 4 kW, 6 kW, 10 kW and 25 kW) to suit different customer requirements. Each scanner model has a corresponding radar processor model. 3.1 10 kW radar system overview The radar system is intended for use in a marine environment. The 10 kW radar system consists of a scanner and an open array, conne

3.2 Check the 10 kW radar parts The NS-RDR1106MO 10 kW radar system consists of a box containing the scanner, a box containing the open array, and a box containing the 10 kW radar processor. The interconnection cable is not supplied and must be ordered separately. It is available in two lengths; NS003105 is the 65.5 ft (20m) length, NS003106 is the 98.4 ft (30 m) length. If you want to use an interconnection cable length other than the 65.5 ft (20 m) or 98.4 ft (30 m) options, please cons

3.3 Install the radar 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 scanner is not rotating. However, a 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 servi

DON'T DO THIS! DON'T install the scanner too high up, where its weight will alter the stability of the vessel and cause degradation of the radar picture over short ranges (see "How to find the optimum height for the scanner"). DON'T install the scanner close to lamps or exhaust outlets. The heat emissions may cause the equipment to breakdown and soot and smoke will degrade the performance of the radar. DON'T install the scanner close to the antennas of other equipment such as direc

However, when the power boat is traveling at high speed, the bow rises up out of the water and if the elevation angle (trim) of the bow is raised up so that it equals, or exceeds, 50% of the vertical beam width of the radar, this can cause two problems: ahead of the power boat, the beam is projected too high to sweep the water surface effectively. Targets can be missed completely or appear at a very poor resolution on the display screen. astern of the power boat, the beam is projected

3.3.2 How to find the optimum height for the scanner The optimum height for the scanner is as close as possible to the A-B line for best performance. How to find the A-B Line: The vertical extent of the radar beam is 2 θ°, so most of the radar beam is concentrated within this angle, meaning that outside of this angle the radar beam will be very weak. Scanner model θ° value (half the -3 dB beam width) 2 kW 15 4 kW 12.5 6 kW 10 10 kW 10 25 kW 10 An example of an A-B Line is

where: D is distance traveled by the radar beam h1 is the height above sea level of the scanner h2 is the height above sea level of a target An example is shown below: In this example, the scanner is installed on the vessel at a height of 10 ft (3 m) above sea level (h1). Island A is 33 ft (10 m) high (h2) and for comparison, Island B is 16.4 ft (5 m) high (h2). Both islands are at a distance (D) of 10 nautical miles from the vessel. Calculations using the formula show that, a

where: Ls = distance to be moved from the keel line D = diameter of the obstacle R = distance between the antenna and the obstacle 3.3.5 Install an open array scanner on a trestle Depending on your chosen location for the scanner, it may be easier to install the scanner if you fabricate a trestle or radar mast on which you can mount the scanner. In this case, the base of the trestle must be installed parallel to the water surface. Orient the trestle so that the main cabling fr

3.3.6 10 kW radar dimensions The 10 kW scanner is an open array model with a rotation diameter of 75.2" (1910 mm). Ensure that the open array will be able to rotate freely and take this diameter into account when calculating the recommended distances from other equipment. Before starting the installation, use the drilling template to identify the: cable inlet safety switch Earth bolt front and rear of the scanner The overall radar dimensions are shown: 3.3.7 Install

Repeat this for procedure for each bolt, then tighten all the nuts so that the scanner is secure. NOTE: Use the bolts supplied as these are hardened stainless steel and the correct length. 3.3.8 When to install the open array IMPORTANT: Install the open array onto the scanner AFTER you have connected the interconnection cable to the scanner otherwise you'll have to remove the open array from the scanner, and then re- install it. 3.3.9 Install the radar processor Install the ra

3.3.10 Wire the radar system Always install a separate circuit breaker or separate fuse for the radar system circuit. 3.10.3.1 Wiring guidelines Most installation problems are caused by shortcuts taken with system cables. When wiring the radar: DON'T make sharp bends in the cables. DON'T run cables in a way that allows water to flow down into the connectors. but DO make drip and service loops. DO use cable ties to keep the cables tidy and secure. DO seal and protect all wi
