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

10 25 kW radar system overview The radar system is intended for use in a marine environment. The 25 kW radar system consists of a scanner and an open array, connected to the 25 kW radar processor by a prefabricated interconnection cable which is available in two lengths (NS003105 or NS003106). where A is the radar processor, B is the vessel's power supply (24 V DC ONLY), and C is the Network Linker (NS004721). The 25 kW interconnection cable contains separate motor power wires

11 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 servic

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

11.1.1 Power boat installations Normally, you should install the scanner horizontally, to produce an equal sweep around the power boat: 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 effecti

11.1.2 Yacht installations Normally you should install the scanner horizontally, to produce an equal sweep around the yacht. However, a yacht heels over to the lee side, and when the heel angle exceeds 50% of the vertical beam width of the radar, this can cause two problems: on the windward side of the yacht, the beam is projected too high to sweep the water surface effectively. Targets can be missed completely or appear at very poor resolution on the display unit. on the lee side

An example of an A-B Line is shown in the picture. If you install the scanner below the A-B line, the scanner will be too low. It will be difficult to acquire distant targets and the superstructure will be more likely to impede the passage of the beam and generate false echoes. If the scanner is installed too high above the A-B line, the beam will miss close targets and increase sea clutter return. You can find the A-B line for any vessel as follows: 1. Using a drawing of the vessel,

Calculations using the formula show that, at this distance, the radar can only detect objects that are more than 25 ft (7.6 m) high, which means that Island A is shown on the radar but Island B is not shown. Remember that: the maximum detection range of the radar is limited by the curvature of the Earth's surface under normal conditions of wave propagation. bad weather conditions can reduce the maximum detection range 11.4 How to reduce false echoes and shadow zones False echoes ca
