CP 225 Original May 03 1 CODE OF SAFE WORKING PRACTICES FOR THE INSTALLATION AND COMMISSIONING OF KELVIN HUGHES LIMITED MANUFACTURED EQUIPMENT This code must be followed when installing or commissioning any Kelvin Hughes Limited product. Failure to follow this code invalidates the equipment warranty. SAFETY Reference must be made to the Safety Warnings located at the beginning of each Kelvin Hughes Limited Manual and must be read and understood. These include but are not limited to, the knowledge and understanding of: ‘Electric Shock Resuscitation’, the safety interlock system, all lethal voltages present, source of supply to all equipment, any hazardous material in the equipment or area of work, radiation hazard from the beam of a Radar Antenna and any antenna rotation hazard. Before working on antennas the following conditions must be met: • A responsible person (such as the officer of the watch) must be informed that there will be an engineer working on the system. • The system interlock must be activated. • The source of power to the system must be isolated. • Warning notices must be posted at the system power source and at all displays showing ‘MAN WORKING ALOFT DO NOT SWITCH ON’. Local language considerations must be taken into account and included with the English statement above. • When working above a height of 1.5 metres safety harnesses must be worn and must be clipped in to the superstructure. • All tools must be securely lashed to ensure that they can not present a drop hazard.
CP 225 Original May 03 2 INSPECTION Before commencing work, the proposed installation locations must be inspected and accepted as being suitable for the equipment to be mounted securely following the installation procedures which can be found in the relevant Kelvin Hughes Limited manual under ‘installations’. All characteristics of the equipment must be taken into account when inspecting the proposed location such as weight and torque of turning mechanisms, regulation height of Radar display units and type, length and specification of cables or waveguide. All equipment must be inspected and checked off against the indent on unpacking, if practicable, for completeness and damage. Any discrepancies against the indent or damage to equipment must be reported to Kelvin Hughes Limited as soon as possible but in any case within 24 hours.

CHAPTER 1GENERAL DESCRIPTIONIN TRO DUC TION1The SharpEyeTM Radar combines the latest concepts, technologies and state of the artperformance in surface search capability into a high reliability product for the maritimeindustry. Comprising an antenna, gearbox and compact transceiver, SharpEyeTM Radarprovides the mariner with a range of highly sophisticated and flexible operating modes and anunsurpassed ability to detect small targets such as buoys, yachts and personal water craft, inmoderate to severe clutter environments. SharpEyeTM radically departs from conventionalmarine navigation radar practice through the transmission of low power RF pulses andapplication of pulse compression and coherent pulse Doppler techniques to provide sub-cluttervisibility of targets.2The SharpEyeTM Radar is available as an X-band Transceiver in upmast configuration(DTX-A3) and is used with the Low Profile Antenna (LPA-A25).3The SharpEyeTM Transceiver operates at fixed antenna rotation speeds of 22 RPM or44 RPM for optimum update rate. The antenna rotation speed is preset during installationand is not selectable by the operator.4The SharpEyeTM Transceiver has a range cell size of between 15 m and 30 m, dependingon the range selected from the display.5Radar control is via a CAN bus to the display system with discrete analogue video, sync,azimuth and heading line signals to the display. 6The SharpEyeTM Transceiver requires 110 V/220 V single phase AC for the transceiverelectronics and 3-phase AC from a Drive Control Unit (GTX-A24) for the antennaturning motor. The Drive Control Unit uses the 220 V ship's single phase mains to generate avariable frequency 3-phase output for the antenna turning motor. The frequency of the 3-phaseoutput determines the antenna rotation speed, and is set by links on installation to provide a 25 Hz output for 22 RPM operation or a 50 Hz output for 44 RPM operation, provided the inputfrequency is 50 Hz. If a 60 Hz input frequency is used the Drive Control Unit must also bereprogrammed as described in Chapter 5 to provide the correct output frequency.7A transformer can be supplied to allow the Drive Control Unit to be used with 110 Vmains supplies.8The Upmast configuration is shown in Figure 1, and a typical implementation in Figure 2.KH1264Chap ter 1Is sue 2 Page 1.3
SYS TEM DE SCRIP TIONTransceiver9The transceiver electronics and the transceiver power supply are mounted in a castenclosure with one removable side cover, secured by seven captive bolts. The transceiver electronics are contained in a unit mounted on the side of the enclosure and the power supply ismounted on the base of the enclosure. The gearbox and motor are mounted on top of theenclosure with the antenna secured to the top of the gearbox on a swing casting.WARNINGTHERE IS NO SAFETY SWITCH ON THE UPMAST TRANSCEIVER/TURNINGMECHANISM. MAN ALOFT SAFETY IS PROVIDED BY AN ON/OFF KEYSWITCH ON THEASSOCIATED DRIVE CONTROL UNIT (FOR DETAILS SEE BELOW). THE ON/OFF KEYSWITCH MUST BE SET TO OFF AND THE KEY REMOVEDBEFORE WORKING ON THE UPMAST TRANSCEIVER/TURNINGMECHANISM. THE INVERTER IN THE DRIVE CONTROL UNIT MUST BE SET TO REMOTEOPERATION DURING COMMISSIONING, OTHERWISE THE KEYSWITCHFUNCTION WILL BE OVERRIDDEN.10 The gearbox has a hollow output shaft through which the rotating joint (rojo) passes. Theoutput shaft also incorporates the mounting for the azimuth encoder, which providesangular position information in the form of azimuth and heading line pulses.11 The azimuth encoder provides azimuth and heading line pulses to the transceiver, whichuses the data internally. The azimuth and heading line pulses are also opto-isolated toprovide outputs to the display system. There are two sets of azimuth pulses in quadrature (eachset providing normal and inverse outputs with 1024 pulses per antenna revolution) and twoheading line pulses (normal and inverse outputs).12 The motor and gearbox operate in conjunction with the Drive Control Unit to rotate theantenna at speeds of up to 45 RPM in winds of up to 100 knots. The motor uses a variablefrequency 3-phase supply of 220 V between phases from the Drive Control Unit.13 The Drive Control Unit uses the ship's single phase mains, which is fed via an inverter togenerate the 3-phase output. The frequency of the 3-phase output determines the antennarotation speed. The Drive Control Unit provides a 'soft start' by controlling the supply frequencyfrom 0 Hz to the operating frequency over a period of nominally 2 seconds.KH1264Chap ter 1Page 1.4Is sue 2
14 The transceiver electronics comprise radar control and timing, waveform generator,solid state transmitter, duplexer, low noise RF receiver, digital receiver, signal processorand communications interface.15 The waveform generator provides frequency modulated pulses at an intermediatefrequency (IF), whose characteristics are determined by the range modes. The IF pulsesare mixed with a local oscillator to provide an RF frequency signal to the solid state transmitter,which provides an RF output at 170 W peak power to a duplexer located within the transceiver.The signals from the duplexer are fed via a coaxial cable to the rotating joint and then to theantenna.16 Return signals from the antenna are fed through the rotating joint to the transceiver,which routes the received signal via the duplexer to an internal low noise RF receiver,digital receiver and signal processor. Sensitivity time control (STC) is applied to the RF receiverto increase the dynamic range. The transceiver provides one analogue SYNC and one analogueVIDEO coaxial output to the display system.17 Internal monitoring of the transmitter and receiver performance is provided, therefore noexternal components are required to ensure operation is satisfactory.18 The power supply, located in the cast enclosure, provides the DC supplies for thetransceiver from the 110 V/220 V single phase mains input. The power supply isautoranging, so no setting up is required for the input voltage.Drive Con trol Unit19 The Drive Control Unit provides a variable frequency 3 phase supply for the antennaturning motor. The Drive Control Unit accepts a 220 V single phase mains supply. Itgenerates a 3 phase supply at either 25 Hz (for low speed antenna operation (22 RPM)) or 50 Hz(for high speed antenna operation (44 RPM)), set up by links made on installation. The defaultinput frequency is 50 Hz to provide these output frequencies. If a different input frequency oroutput frequency are used, the Drive Control Unit must be reprogrammed as described inChapter 5. The Drive Control Unit provides a 'soft start' of nominally 2 seconds, and a 'soft stop'of nominally 10 seconds for the antenna. This reduces torque when the antenna is started andstopped. If required, a transformer can be fitted to the mains input to enable the unit to be usedwith 110 V mains.20 The Drive Control Unit has two indicators and a switch on the top of the unit. Theindicators are MAINS ON, which is lit when the single phase mains input is present andMOTOR ON, which is lit when the 3 phase output to the motor is present. The switch provides aman aloft safety function, and is key operated. The key can only be removed when the switch isset to OFF. When set to OFF, the 3 phase output is inhibited, thus preventing the antenna fromrotating. When set to ON the key is captive in the switch and the 3 phase power to the antennamotor is enabled. Note that when the switch is set to OFF the MOTOR ON indicator will alwaysbe unlit.KH1264Chap ter 1Is sue 2 Page 1.5
WARNINGALWAYS SET THE KEYSWITCH TO OFF AND REMOVE THE KEY WHENWORKING ON THE UPMAST TRANSCEIVER. THIS PREVENTS THEANTENNA FROM ROTATING. THE INVERTER MUST BE SET TO REMOTE OPERATION DURINGCOMMISSIONING, OTHERWISE THE KEYSWITCH FUNCTION WILL BEOVERRIDDEN.KH1264Chap ter 1Page 1.6Is sue 2ANTENNAROTATINGJOINTMOTORTRANSCEIVERSYNCVIDEOTO/FROM DISPLAYPOWER GEARBOXPOWER UNITTRANSCEIVER ASSEMBLYDTX-A31 PHASE MAINS ININVERTER STARTAZIMUTH/HEADING LINEDRIVECONTROL UNITGTX-A24AZIMUTHENCODERDC SUPPLIES1 PHASE MAINS INTURNINGMECHANISMCD-7616 ISSUE 1CANBUS CONTROL/STATUS CAN ADAPTERON/OFFSWITCHAZIMUTHINTERFACEFigure 1 - SharpEyeTM Transceiver: Block Diagram

FUNC TIONAL DE SCRIP TION6Functional diagrams of the transceiver and antenna are shown in Figure 3 and theinterconnections in Figure 4.TRANSCEIVERMo tor and Gearbox7The antenna motor is driven by a 3 phase supply from the inverter in the Drive ControlUnit. The Drive Control Unit is configured to provide a soft start and a soft stop for themotor, so that the motor takes a few seconds to reach normal antenna rotation speed and a fewseconds to slow down when stopped. This reduces the start up and stopping torque on the motor.The motor is connected to the antenna by the gearbox which provides the drive to the antenna.8The Azimuth and Heading Line pulses are generated by the Azimuth Encoder, which ismounted on the output shaft of the gearbox. Part of the Azimuth Encoder rotates with thegearbox and part remains stationary with the enclosure. The Azimuth Encoder uses an opticaldisc with sensors.9Two heading line pulses (heading line and inverse heading line) and two sets of 1024pulses per revolution azimuth pulses (each set comprising azimuth and inverse azimuth)are produced for each rotation of the antenna. The two sets of azimuth pulses are produced inquadrature (called Q1 and Q2 pulses), with Q2 lagging Q1 pulses by 90° when the antennarotates in the normal direction. This allows the azimuth data to be used to detect reverse rotationof the antenna (which may occur due to windage when the motor is switched off) as Q2 pulseslead Q1 pulses by 90° when the antenna starts to rotate in the reverse direction. The AzimuthEncoder is supplied with +15 V, which is used to generate azimuth and heading line outputpulses of +15 V. The pulses are passed directly to the display system via TB1 and also to theSharpEyeTM Azimuth Interface PCA (DTX-A151), which opto-isolates the signals before theyare routed to the Transceiver (DTX-A115).10 The phase of the azimuth inputs for normal and reverse rotation is shown below.KH1264Chap ter 3Page 3.6Is sue 2Q1Q3Q2Q4Q2 TO Q190 DEGREEPHASE LAGQ2 TO Q190 DEGREE PHASE LEADANTENNADIRECTION REVERSES
Trans ceiver (DTX-A115)11 The transceiver uses solid state components and provides a signal generator andfrequency synthesiser, up-converter, solid state RF power amplifier, duplexer, low noiseRF receiver, down-converter, digital receiver, digital signal processor and a LAN interface. Thetransceiver produces a peak power output of ³170 W. The solid state design provides excellentreliability and has no lifed items. Note that the unit is not repairable in the field and must bereturned to the manufacturer for repair. The following description is for information only.12 The transceiver is capable of transmitting and receiving pulses of RF energy whosecentre frequency is contained in the band 9.22 to 9.48 GHz and is capable of inhibitingthe transmission of pulses of RF energy over an azimuth sector defined by the display system.Timing Circuits and Azimuth Data Processing13 There are two reference clock outputs, which output squarewaves with a frequency of80 MHz ± 80 Hz. The local oscillator is phase locked to the reference clock. All the clockand timing circuits are derived as multiples of this reference clock.14 The local oscillator produces a sinusoidal output with a frequency of 640 MHz ± 1.3 kHz. This is used with the transmit and receive circuits for up- and down-conversion.Transmitter Circuits15 The signal generation and frequency synthesis circuits use a waveform generator thatprovides frequency modulated pulses at an intermediate frequency. The characteristicsof the pulses are determined by the range and rotation modes, i.e. the instrumented range selected and the antenna rotation speed selected. The waveform generator employs digital synthesistechniques and outputs frequency modulated pulses with a centre frequency of 60 MHz ±200 Hz. The within pulse frequency modulation is phase contiguous.16 The up-converter converts the IF signals from the waveform generator to RF frequencyin three stages. The bandwidth of the first intermediate frequencies within the upconverter are 60 MHz ±12 MHz and 140 MHz ±12 MHz. The bandwidth of the secondintermediate frequencies within the up converter are 500 MHz ±20 MHz and 580 MHz±20 MHz. The bandwidth of the third intermediate frequencies within the up converter are1140 MHz ±20 MHz and 1220 MHz ±20 MHz.17 The RF frequency signal is fed to the solid state power amplifier, which provides an RFoutput at ³170 W peak power to a duplexer located within the transceiver. Note that thepower amplifier stage is switched off between sending each of the pulses in order to maximisereceiver sensitivity. The signals from the duplexer are fed via a coaxial cable to the rotating jointand then to the antenna.KH1264Chap ter 3Is sue 2 Page 3.7
Receiver Circuits18 Return signals from the antenna are fed through the rotating joint to the transceiver,which routes the received signal via the duplexer to an internal low noise RF receiver,digital receiver and signal processor.19 Sensitivity Time Control (STC) is applied to the low noise RF receiver to increase thedynamic range of the receiver. The noise figure of the receiver is £4 dB, measured at theoutput of the analogue to digital converter. The low noise receiver contains the capability toadjust the mean noise level prior to analogue to digital conversion.20 The output from the low noise RF receiver is converted to a third intermediate frequencyin three stages. The bandwidth of the first intermediate frequency is 1220 MHz ±20 MHz. The bandwidth of the second intermediate frequency is 580 MHz ±20 MHz. The bandwidth ofthe third intermediate frequency is 60 MHz ±12 MHz.21 The intermediate frequency is applied to an analogue-to-digital converter which outputs14 bit two’s complement digitised samples to the digital receiver. The centre frequencyof the digitised samples is 20 MHz ±80 Hz and the instantaneous bandwidth is £20 MHz. 22 The digital receiver translates the signals to the baseband frequency and providesIn-phase and Quadrature (I and Q) outputs to the digital signal processor. The in-phaseand quadrature phase outputs of the digital receiver are both rounded to 18 bits, and the format ofthe output is two's complement.23 The digital signal processor uses digital pulse compression before applying the signals tothe limiting and compensation function. Motion compensation removes the effect of own ship motion from the received signal vector. The limiting and motion compensation function hasa Doppler output channel and a Logarithmic output channel.24 The Doppler channel is currently not implemented.25 The input to the Logarithmic channel is used for video processing. The video processingfunction aligns the amplitude data into a contiguous range ordered data stream, aligns the single bit detection video into a contiguous range ordered data stream and aligns the logarithmicamplitude data into a contiguous range ordered data stream.26 The video is converted to analogue video for output to conventional display systems, e.g.Nucleus 3, Manta and MantaDigital. In the future digital video will also be output fromthe LAN link.27 Due to the characteristics of RACON systems, the processing applied to targets andobjects within the digital signal processor is not suitable for the detection of a RACON.To solve this, a specific RACON processing channel is included. This enables RACON signalsto be processed and integrated into the surface picture processed video output.KH1264Chap ter 3Page 3.8Is sue 2
Operating States28 The transceiver has the following six operating states:(1) Off. In this state power is not applied to the transceiver and it is switched off.(2) Initialise. When power is applied to the transceiver it enters initialise state. Thetransceiver automatically loads any software or configuration files and suppliesDC power to the azimuth encoder. On completion of initialisation the transceiverswitches to Standby state.(3) Standby. In this state the transceiver establishes communication with the display system and reports its status to the display system. The transceiver receives andacts on commands from the display system and provides azimuth and headingline data from the encoder to the display system. The transceiver does not radiateRF in this state.(4) Transmit. On receipt of a Run command from the display system, provided thedisplay system has defined all the operating conditions, the transceiver switchesfrom Standby to Run state. The transceiver initially outputs an RF signal into theantenna at low power. This enables the VSWR to be checked without the risk ofdamage to the transceiver, e.g. from an open circuit into the antenna. If the VSWR is within limits then the transceiver automatically switches to full power. If theVSWR is high, indicating an antenna fault, a warning message is sent to thedisplay system and the transceiver does not radiate on full power. The radarreturns are then processed to provide radar video to the display system. Note thatthe time from switch on to being ready to enter the run state is less than 2 minutes.(5) Degraded. The transceiver continuously runs background performance checkson forward power, reverse power and receiver sensitivity. If any of theseparameters is outside predetermined levels a warning message is sent to thedisplay system indicating the nature of the fault. The transceiver continues tooperate, but with reduced performance and functionality. The fault should beinvestigated at the earliest opportunity.(6) Fault. If the performance or functionality is degraded such that the transceivercannot operate it enters the fault state and a fault message is sent to the displaysystem. The transceiver stops radiating RF and there is no video to the display.Operating Range29 In either the Transmit or Degraded states the radar operates in one surface picture modewith a range of interest of 48 nm. The operating range is determined by the Range Scalesselected on the display. 24 nm mode is applied when a range scale of 24 nm or less is selected.48 nm operating range is selected for range scales greater than 24 nm.KH1264Chap ter 3Is sue 2 Page 3.9
Installation and Setting to Work Parameters30 The SharpEyeTM Transceiver contains a number of operational settings that are set upduring system installation and setting to work. These operational settings are:(1) Rotation Rate. The transceiver supports 2 nominal antenna rotation rates, 22 rpmand 44 rpm. System behaviour and performance varies depending upon whichrotation rate is selected as the system parameters are adjusted for the differentrotation rates.(2) Operating Frequency. The transceiver contains 14 pre-set transmissionfrequencies within the operating frequency band. The frequency used for aparticular system is set during system installation and setting to work. The centrefrequencies of each RF band are:(a) 9.22GHz ±15 kHz.(b) 9.24GHz ±15 kHz.(c) 9.26GHz ±15 kHz.(d) 9.28GHz ±15 kHz.(e) 9.30GHz ±15 kHz.(f) 9.32GHz ±15 kHz.(g) 9.34GHz ±15 kHz.(h) 9.36GHz ±15 kHz.(i) 9.38GHz ±15 kHz.(j) 9.40GHz ±15 kHz.(k) 9.42GHz ±15 kHz.(l) 9.44GHz ±15 kHz.(m) 9.46GHz ±15 kHz.(n) 9.48GHz ±15 kHz.(3) Transmit Inhibit Sector. The transceiver provides one blanking sector that isconfigured via the display system. The radar does not transmit RF energy withinthe blanking sector.KH1264Chap ter 3Page 3.10 Is sue 2
Monitoring31 If the RF output power falls below 100 W the transceiver sends an RF Power warningmessage to the display system and switches to the Degraded state of operation.32 If the VSWR on the RF output is above 2.0:1 the transceiver sends an Antenna VSWRwarning message to the display system and switches to the Degraded state of operation.33 If the minimum detectable signal rises above a preset level the transceiver sends aReceiver Sensitivity warning message to the display system and switches to theDegraded state of operation.34 If the transceiver detects hardware faults (frequency synthesis or phase locked oscillatorfailure), it sends a warning message to the display system and switches to the Degradedstate of operation.35 If communication between the transceiver and the display system is lost for > 5 secondsthe transceiver switches to the fault state.36 If the temperature of the RF power transistors in the transceiver exceeds a predeterminedlimit, the transceiver sends an Overtemperature warning to the display system andswitches to the Degraded state. If the temperature exceeds a further preset limit the transceiverswitches to the Fault state. As the temperature drops below the predetermined limits thetransceiver returns to the Degraded state and then to normal Transmit operation.CAN Bus Interface37 The CAN bus signals to and from the display system are routed via the CAN AdapterPCB (NNR-A981), which interfaces the CAN bus to the RS232 interface on theTransceiver (DTX-A115). The CAN Adapter PCB converts the RS232 signals from theTransceiver into CAN bus signals for routing to the display, and converts the CAN bus signalsfrom the display to RS232 signals for application to the transceiver.+15 V Supplies38 +15 V from the transceiver is routed to the SharpEyeTM Azimuth Interface PCB(DTX-A151). The SharpEyeTM Azimuth Interface PCB routes the +15 V to the Encoder and the CAN Adapter PCB (NNR-A981).Power Sup ply (45-690-0062-002)39 The transceiver uses 110 V or 220 V single phase mains, which is passed through a mainsfilter before application to the Switched Mode Power Supply. The Power Supplyprovides the following DC supplies for the transceiver module:(1) +3.3 V at 5.0 A for the digital processing circuits.(2) +15 V at 5.0 A for the digital processing and amplifier circuits.(3) +13 V at 6.0 A for the amplifier circuits.KH1264Chap ter 3Is sue 2 Page 3.11

DRIVE CON TROL UNIT (GTX-A24)40 The drive control unit provides 3 phase supplies for the antenna turning motor in theSharpEyeTM Upmast Transceiver. It accepts a 220 V single phase mains supply andgenerates a 3 phase supply at either 25 Hz or 50 Hz with the frequency set internally, either ofwhich may be selected from the display, or by physical wire links on the Drive Control Unit.25 Hz is used to provide an antenna speed of 22 rpm and 50 Hz is used to provide an antennaspeed of 44 rpm. If required, a transformer can be fitted to the mains input to enable the unit to beused with 110 V mains.41 Figure 5 shows the interconnections within the Drive Control Unit. The Drive ControlUnit comprises:(1) Inverter (45-690-0033-001)(2) Drive Interface PCB (GTX-A104)(3) Mains input filter (part of Power Input Cableform GTX-A217)(4) Man Aloft Keyswitch (45-613-4205)(5) Output filters (ferrite cores - part of Power Output Cableform GTX-A196)42 The presence of the mains input is indicated by the MAINS ON neon indicator (LP1) onthe top of the unit being lit.43 The mains input is passed through the input filter, which slows down the rate of rise ofcurrent input pulses to reduce the generation of interference. The mains is then applied tothe inverter, which converts the single-phase input at 50/60 Hz into 3-phase at 0 Hz to 120 Hz(variable). The 3-phase output is generated as switched mode power pulses. These pulses are atthe peak output voltage, which is approximately 320 V with 5 kHz switching frequency. Theeffective rms voltage at the output varies from 130 V to 230 V AC depending on the antennamotor load.44 The output frequency sets the speed of antenna rotation. The output frequency is set to25 Hz for 22 rpm and 50 Hz for 44 rpm antenna rotation speed. The speed is set at theinverter on installation and if the inverter is replaced, the new inverter must be correctly set afterrepair. Note that the inverter is set on installation to provide a 25 Hz or 50 Hz output using wirelinks. The output frequency is also dependent on the input frequency, so that the new invertermust be programmed for 50 Hz or 60 Hz input as described in Chapter 5. Most of the settings arethe manufacturer's defaults, but others must be set up as specified.45 The inverter is set to provide an acceleration time of 2 seconds before reaching full speed, this provides a soft-start function for the antenna on start up. When the power is switchedoff, the inverter provides a deceleration time of 10 seconds to slow the antenna rotation. Thesefunctions reduce the torque on the antenna during starting and stopping.46 The Drive Interface PCB (GTX-A104) provides the control interface to the inverter. Italso provides the interface to external control lines to allow one of the antenna speeds tobe selected by wire links on installation. It uses opto-isolators to allow the control signals to theinverter to be compatible with the inverter.KH1264Chap ter 3Is sue 2 Page 3.17
47 The inverter is switched on by applying +12 V to +28 V across PLA pins 1 and 2 on theDrive Control PCB. The positive voltage is routed via PLC pin 5 to the Man AloftKeyswitch (SW1), which is located on the top of the unit. This switch disables the +12 V to +28 V to the inverter when set to the OFF position, thus switching the inverter off, regardless of theinput condition, provided the inverter has been set for remote operation. The key is removable inthe OFF position only and is captive in the ON position. This enables antenna rotation to beinhibited to allow safe man aloft working.WARNINGTHE INVERTER MUST BE SET TO REMOTE OPERATION TO ENABLE THEKEYSWITCH TO SWITCH THE INVERTER ON AND OFF. UNDER NOCIRCUMSTANCES SET THE INVERTER TO LOCAL OPERATION AS THISWILL OVERRIDE THE SAFETY FUNCTION.48 The voltage from the keyswitch is routed to PLC pin 6 on the Drive Control PCB. Whenthe +12 V to +28 V is present at PLC pin 6, an opto-isolator on the Drive Control PCB isswitched on, linking PLB pins 1 and 2 to switch the inverter on. When the +12 V to +28 V is notpresent at PLC pin 6, either by the absence of the input on PLA pin 1 or by the keyswitch being set to OFF, the opto-isolator is switched off and PLB pins 1 and 2 are open circuit, thus switching theinverter off.49 A MOTOR ON LED (D1) on top of the unit is lit when 3-phase power is available to themotor from the inverter. Two of the phases from the inverter are passed to the DriveControl PCB, which converts the signal to a DC level suitable for the LED.50 Each output wire passes through a ferrite core to reduce the rate of rise of current, whichreduces the generation of interference. The ferrite cores form part of the output cable.51 The inverter is used with Speed 1 and Speed 2 inputs, which operate in the same way, soonly Speed 1 input is described. Speed 1 switches on an opto-isolator when PLA pin 3 isconnected to the negative side of the start input (PLA pin 2) and +12 V to +28 V is present at PLCpin 6. The output is used to link the appropriate inverter speed selector terminals. Using Speed 1input gives a two speed selection, depending on whether PLA pin 3 is connected to PLA pin 2 oris open circuit. In this application PLA pin 3 is linked to PLA pin 2 for low speed and is opencircuit for high speed. Speed 2 (PLA pin 4) is always linked to PLA pin 2.52 Future enhancements will allow the Drive Control Unit to provide the facility to select up to four antenna speeds, by controlling Speed 1 and Speed 2 inputs from an externalsource. This will allow one of up to four preset speeds to be selected to meet the operationalrequirements of the system.KH1264Chap ter 3Page 3.18 Is sue 2

SAFETY NOTESObserve the Health and Safety Notices at the front of this manual. Inparticular, the procedures given in the Code of Safe Working PracticesCP225 MUST be followed. Failure to follow these procedures and tocomplete and return the Warranty card will invalidate the warranty on the equipment.7Safety personnel must ensure that persons do not encroach on the area of work.8Electrical supplies are to be isolated to any part of the platform when mounting an upmast transceiver/turning mechanism. A suitable safety platform or harness should be used toavoid personal injury when working aloft.9Electrical supplies in the vicinity of the transceiver are to be isolated during installation.10 A working platform is to be provided for installing or servicing the assembly. This should be positioned approximately a metre below the base of the Upmast Transceiver housingwith a guard rail surrounding it.11 The Upmast Transceiver must be hoisted to the fixing position using a secured block andtackle or rope strops.12 The Upmast Transceiver MUST NOT be lifted by the array, but the complete unitsecured and hoisted evenly.

EQUIP MENT LO CA TIONUPMAST TRANS CEIVER (DTX-A3)13 The Upmast Transceiver should be installed in such a position where Blind Arcs, causedby obstructions, i.e. masts, funnels etc, are eliminated or minimised. Funnels, crosstreesand other large obstructions can also reflect energy and give rise to spurious echo returnsespecially in close proximity to land. Positioning the antenna close to funnels and exhaust gasescan adversely affect antenna performance.14 The Upmast Transceiver is to be mounted on a rigid platform, which is positioned so thatthe rotating antenna is clear of other structures.15 The primary consideration must be the strength of the support for the UpmastTransceiver/Antenna assembly. Details of the requirement are described in the following sub-paragraphs:(1) The antenna must be mounted more than 914 mm (3 ft) above any flat surfacegreater than the diameter swept by the antenna. It must not be positioned in closeproximity of any magnetic compass or D/F aerial etc.(2) Masts, sampsons, posts and rigging of more than 0.6 m (2 ft) diameter can causeblind sectors. Increasing the distance between the antenna unit and these objectswill reduce the blind sectors that inhibit a good radar picture.16 The Upmast Transceiver must not be mounted where the temperature exceeds 70oC.17 The Upmast Transceiver must be kept clear of ship’s flexible communication aerials toavoid damage to both.DRIVE CON TROL UNIT (GTX-A24)18 The Drive Control Unit is designed for bulkhead mounting and must be sited as near theTransceiver as possible, the maximum cable run between the Drive Control Unit andTransceiver is 65 m.19 The Drive Control Unit must be sited to allow removal of the front cover, access to thecable glands and removal of the key from the keyswitch, which is essential when working aloft.OP TIONAL MAINS ISO LA TOR (80-261-600)20 The Mains Isolator must be sited adjacent to the display or in the area of the operatorscontrol room and connected in parallel with the main display.KH1264Chap ter 4Is sue 2 Page 4.5

AC CESS TO THEIN TE RIOR OF THE UNIT IS ONLY TO BE CARRIED OUT BY A QUAL IFIEDTECH NI CIAN.4The flowcharts in this chapter provide an aid to fault diagnosis in the transceiver. Thealgorithms enable fault diagnosis down to module level and also identify wiring faults.Entry to the algorithms is via Failure Messages generated by the display.PRE-REQ UI SITES5The diagnostic routines in the flow charts assume that the radar has been working, andthat the system is set up for normal operation at the time the fault occurred.FAIL URE MES SAGES6These failure messages appear in the data field of the display monitor if certain signalsare missing. One or more of the following messages may be displayed on the displaysystem:(1) No Sync. Indicates that the display is not detecting sync pulses from thetransceiver.(2) No Video. Indicates that the display is not detecting video from the transceiver.(3) No Azimuth. Indicates that the display is not detecting azimuth pulses from thetransceiver.(4) No Heading Line. Indicates that the display is not detecting heading line pulsesfrom the transceiver.7The following messages are supplied from the transceiver via the CAN bus, which mayswitch to degraded mode of operation (low power output, low sensitivity etc) or faultmode:(1) Receiver Sensitivity Low. This indicates that the minimum detectable signal is³TBD dB, indicating a receiver fault. The transceiver continues operating in thedegraded state. Should the minimum detectable signal be ³TBD dB, thetransceiver will enter the fault state.(2) Antenna VSWR High. The transceiver has detected a high reverse power andhence VSWR. This indicates that there is a mismatch in the transceiver output tothe antenna, e.g. an antenna or rotating joint fault.(3) RF Power Low. The transceiver has detected low power on the output. If thepower is 3 dB below normal this indicates that one of the two RF outputtransistors in the transceiver has failed, i.e. a fault in the transceiver unit. Thetransceiver continues operating in a degraded state on half power. Should thesecond RF output transistor then fail, the transceiver will enter the fault state.KH1264Chap ter 6Page 6.4Is sue 2
(4) PLO Lock. Indicates that the phase locked oscillator has developed a hardwarefault.(5) Synth Lock. Indicates that the frequency synthesiser has developed a hardwarefault.(6) Transmitter Over-temperature. This indicates that the temperature of the RFpower transistors is high, indicating a fault in the transceiver.8Fault diagnosis algorithms covering these failures is provided in Figure 3.TEST EQUIP MENT9Fault location is to module replacement level only.
