Up Mast S-Band Installation 9.4 INSTALLATION 9.4.1 Installation principles In order to obtain the best radar performance and accessibility, the following precautions should be used:

- Space for the antenna to swing freely. See par.9.2 (Specifications; Antenna type)

- Safety and easy access for maintenance purposes. It is preferable to use a platform on the ship mast.

- The antenna to be accessible in all directions

- Avoid exposure to exhaust fumes from the funnel

- Avoid strong vibrations

- Avoid interference between two antennas

- Avoid obstacles in the radar beam, especially ahead of athwart ships directions If two radar sets are installed, their antennas should be installed on different levels. The antennas can be mounted, either on a single mast construction, so they are on top of each-other or the antennas can be mounted on a platform, one on portside and one on starboard side. The following formula and drawing, will help you to determine the correct distance and height between the two radar antennas. The 45 angle on the drawin g is the actual vertical beam-width with a safety margin included. Example:

H = L, H = height between the two antennas L = the distance between the two antennas If the distance L is 6m, then the height should be = 6m. Blind sectors towards the bow and within a few degrees on port and/or starboard side caused by the structure of the ship must be avoided with great care. In case of a blind sector at the bow in mid-ships position, it is advisable to mount the antennas on the starboard side of the ships keel-line. When obstacles are sufficiently far from the antenna, they will result in a blind sector on the radar display with approximately the same amplitude as observed by the human eye, but these obstacles can produce false echoes. An echo produced by an obstacle close to the antenna, can be suppressed by reflecting the antenna-beam skywards by mounting a reflector made of metal. This solution however does not eliminate the blind sector, but will reduce false echoes produced by the obstacle. The best position for the reflector can be found by testing out different positions. MAN-SRTSUP-001 9.7 Rev.1 Up Mast S-Band Installation It is highly recommended that the shipyard submit the drawings of the radar antenna position(s) to the manufacturer for approval. The Installation consists of following basic steps:

- Mount the Unit without the Antenna on the mast

- Make relevant connector

Install and connect the Performance Monitor (optional) arm Install the Safety Switch

- Mount the Antenna on the Unit NOTE The transceiver should be installed in such way that the performance monitor arm is not facing funnels or other big ships obstruction. Sector blanking is enabled to prevent false echoes caused by funnels and/or big ships construction (see above). If performance monitor arm is positioned, within this blanking area, the pedestal must be turned because the radar performance monitor is not working where there is no transmission in the sector of its sensor Installation of Safety Switch CHANGE: IT IS ON THE DC CORE OR ADAPTER BOX OR OPTIONAL FOR THE ADAPTER BOX EXTERNAL is compulsory. It is recommended to be installed at the bottom of the stairs giving access to the Antenna Pedestal. The waterproof switch is supplied by manufacturer, but a connection cable (2x2,5mm2) should be provided by the shipyard.

An essential operating or maintenance procedure, condition or statement which must be highlighted. NOTE MAN-SRTSUP-001 1.1 Rev.1 Up Mast S-Band General Information and Safety Precautions When a precaution is required which relates specifically to a part of the technical manual contents, the information is given in the relevant part of the manual. Warning and Cautions precede applicable text. 1.1.1 High voltage Radar equipment requires the use of high voltages. This can cause injury, or loss of life. Danger exists only when the units are opened, exposing internal circuits, as when servicing the equipment. You do not face any danger during normal operation. The SRT S-Band Radar System has been carefully designed to protect personnel from possible injury from high voltages at normal operation. When inspecting or servicing the equipment, nevertheless, it is recommended that the Line Switch to left open, as an added protection. Although every effort has been made to eliminate danger to personnel, no responsibility is accepted for any injury or loss of life suffered in connection with the equipment. 1.1.2 Safety switch The Radar Unit is provided with a safety switch, which disable the Antenna movement during maintenance operations and avoids high voltage damage. Always turn the safety switch off, whenever advised in this manual (for instance, before performing any maintenance or installation procedure). Ignoring safety switch operation may produce hazard of electrocution as well as other severe injures. 1.1.3 Safety precautions Purpose The safety precautions described in this paragraph are applicable to Up Mast S-Band. Depending upon the material to be highlighted, the following attention letter headings are used in the technical manual content. An essential operating or maintenance procedure, condition or statement which must NOTE be highlighted. Whenever a precaution, relating specifically to a part of the technical manual is needed, the information is given in the relevant part of the manual. Warnings and Cautions precede applicable text. Safety Operations During normal operation (front cover closed), the unit can be quickly disconnected from the main power line, setting to OFF the relevant circuit breaker located on the electric switchboard. During maintenance (front cover opened) it is possible to turn-on the unit by setting to SERVICE MODE the SW2 switch, mounted on the RTM Supply Assy. This switch is connected in parallel with the relay, controlled by the POWER ON command, and during normal operation must be set to MAN-SRTSUP-001 1.2 Rev.1 Up Mast S-Band General Information and Safety Precautions NORMAL. During maintenance, in order to prevent RTM occasional turning-on it is better to disconnect and insulate, momentarily, PWON terminal from the relevant terminal board. Main power line is always present on terminal board and on fuses. NOTE Safety Summary The following are general safety precautions that are not related to any specific procedure and therefore do not appear elsewhere in this technical manual. These are recommended precautions that personnel must understand and apply during most phases of operation and maintenance. Operating personnel must at all times observe all safety regulations. KEEP AWAY FROM LIVE CIRCUIT Do not replace components or make adjustments inside the unit with the high voltage supply turned ON. Under certain conditions, dangerous potentials may exist when the power breaker is in the OFF position, also due to charges retained by capacitors. To avoid casualties, always remove power and discharge to ground a circuit before touching it. DO NOT SERVICE OR ADJUST ALONE Under no circumstances should any person initiate servicing or adjusting the unit except in the presence of someone capable of helping help. RESUSCITATION Personnel working with or near high voltage should be familiar with modern methods of resuscitation. Such information may be obtained from the Bureau of Medicine and Surgery. Warning Information The following warnings appear in the text of this technical manual, and are repeated here for emphasis. WARNING USE EXTREME CARE WHEN WORKING ON THE UNIT ONCE THE COVER HAS BEEN OPENED. THE MAGNETRON ASSEMBLY OPERATES AT VOLTAGES THAT MAY PROVE FATAL. WARNING BEWARE OF HIGH VOLTAGE CAPACITORS. IT IS NECESSARY TO SHORT-

CIRCUIT THEIR LEADS BEFORE PERFORMING ANY MAINTENANCE ACTION ON THEM. WARNING ON THE ELECTRIC SWITCHBOARD, SET TO OFF THE POWER BREAKER DEDICATED TO THE PRESENT EQUIPMENT AND HANG TO IT A PLACARD READING: WORK IN PROGRESS-DO NOT SWITCH ON. MAN-SRTSUP-001 1.3 Rev.1 Up Mast S-Band General Information and Safety Precautions WARNING USE EXTREME CARE WHEN WORKING ON THE EQUIPMENT ONCE THE FRONT COVER HAS BEEN OPENED. THE MAGNETRON ASSEMBLY OPERATES AT VOLTAGES THAT MAY PROVE FATAL. SET MAIN LINE BREAKER TO OFF BEFORE REPLACING ANY FUSE. FUSES ARE UNDER VOLTAGE LEVELS WHICH MAY PROVE FATAL. WARNING 1.1.4 X-ray radiation X-RAY radiation may be generated by Transceiver units and care must be taken to avoid possible harmful effects when they are opened for maintenance. When power is on, care should be taken not to approach closer than 1 ft. from the unit unless front cover is in place. 1.1.5 Radio-frequency radiation Harmful effects (particularly to the eyes) may be caused by exposure of any part of the human body to radio-frequency mean power densities. Hazard distances at which power densities of 100 W/ m, 50 W/ m and 10 W/m exist, are given in the following table. Table 1.1.1 Hazard zone Configuration On the antenna surface

[W/m]

Distance at 0,9 m in front of the antenna [W/m]

30 kW Transceiver + 12'S-Band Antenna

(ANT12S/LP ) 28 10 The system is however designed to disable radiation when the antenna is not rotating. The pedestals have also been predisposed for the installation of an external safety switch, which can be mounted on, or near the platform. This switch removes power from the Pedestal eliminating the possibility of accidental operation during servicing and also causes disabling of transmission. Whenever it is necessary to disconnect the waveguide system from a radar transmitter for maintenance purpose, the transmitter output should, when practicable, be terminated in a matched load. If this is not possible, care should be taken to avoid standing in front of an open-ended waveguide from which power is being radiated. NEVER look down a waveguide/coaxial cable from which power is being radiated. MAN-SRTSUP-001 1.4 Rev.1
