The main transmitter is connected to the antenna, while the standby transmitter is connected to dummy load. A failure in the main transmitter will cause an automatic change over to the standby transmitter.The audio signals are generated in the LF circuitry mainly by a Field Programmable Gate Array (FPGA). A strap field selects Inner, Middle or Outer Marker settings.An onboard oscillator generates a 75MHz carrier wave which is amplitude modulated with the LF GENERATORRF OSCILLATORPOWERAMPLIFIERCHANGEOVERLOCALCONTROLTX1/TX2ON/OFF75 MHz400 Hz1.300 Hz3.000 HzKEYBOARDDISPLAYADCPUNM7050 - MARKER BEACONSTATIONCONTROLADCPUMONITORINGMAINTENANCE +RMM INTERFACEMONITOR RFFRONTEND MONITORBASEBAND+RF LEVELOPTIONAL MONITOR 2 REMOTECONTROLSLAVEPANELLOCAL PCREMOTE PCRMMPOWERSUPPLYCONNECTIONINTERFACETRANSMITTER 1 TRANSMITTER 2 MONITOR RFFRONTEND MONITORACDCDCDCLINE+MODEMMONITOR 1 OPTIONAL POWERMO 1374MO 1374TX 1373LC 1377CI 1376PS 1375DUMMYLOADMAINS BATTERY SENSORS ETC.BASEBAND+RF LEVELMAINTENANCE +RMM INTERFACE MONITORINGSTATIONCONTROLSPLITTER ONLY PRESENT IF TWO MONITORSLF GENERATORRF OSCILLATORPOWERAMPLIFIER75 MHz400 Hz1.300 Hz3.000 HzTX 1373ON/OFFMODULATION DEPTHOUTPUT RF LEVELKEYING NORMAL/OFF/CONT.STATUS+20V+/-15V+5VMONITOR 2DATALINE+MODEMHBK782/1RMM

The PA is capable of delivering up to 4W power at 97% depth of modulation.Unwanted frequencies are removed by a lowpass filter after the PA.3.3 Monitors / Transmitter Control The marker beacon has one or two MO1374 monitor modules depending on model (Table 3-1). The MO1374 is mainly a microprocessor based module. It contains the MB software and forms the basis of the monitor, station control, system maintenance handling and RMS user interface.A detection of error in the transmitter signal causes change-over to the standby transmitter. Failure of the standby transmitter leads to an alarm and optional shutdown of the standby transmitter.On a system with two monitor units, both must report error for alarm to be generated (2 of 2 voting). If the monitors disagree, the WARNING and DISAGR LEDs on the front panel is lit.The MO1374 consists of two submodules:The RF frontend receives a RF signal from the antenna (or recombining network for dual antenna system). It demodulates the signal into analogue values propotional to the RF power, the modulation depth and the morse code envelope. These parameters are digitized and monitored by the CPU section.The CPU section includes an 80CI88 CPU, memory, communication ports and an AD con-verter system.3.4 Power SystemsThe marker beacon can have either one or two PS1375 power modules depending on model (Table 3-1). The PS1375 is 100W with 120V or 230V AC input voltage and +28V/3.5 A, +20/2.5A, ±12V/1.25A and 5V/6A DC output voltages. Outputs are short circuit protected. On the NM7050 B/D the two modules operate in parallel.The 28V output is temperature compensated to ensure optimum battery charging. It gives 26.4V at 50°C and linearly increase to 29.6V at -30°C.The backup battery is an external 24V battery. The battery gives a backup time of 6 hours, and have external charging possibilities for longer backup time. This battery is automatically brought into circuit on mains power failure. The charging time is approximately eight hours with one PS1375 and five hours with two PS1375.3.5 Remote control systemThe remote control unit is used in the tower or in the technical control room. It has indicators for operating status as well as detailed warnings and an aural alarm device with reset. It can control equipment on/off and change over, and has an Access Grant switch to allow/inhibit remote control from the RMM system.

This system con-sists of the RMS system, remote PC terminals with the RMM program installed, and the local keyboard/display. Figure 3-2 illustrates the RMM/RMS systems.Figure 3-2 The NM 7050 RMM/RMS systemsThe centre of the RMM system is a CPU with the RMS core program. The RMS collects mea-surements and diagnostic data, and makes them available to the user. The collected informa-tion allows easy and cost effective maintenance, fault finding and routine reporting. In addition, system settings are distributed and parameter readings are collected via the RMS/CPU.External Personal Computers are used for a user friendly interface to the RMM system. The equipment has two serial output ports, typically used to connect a local PC and a connection to a central maintenance facility.RMShardwareRMScoreprogramLocalmeasuringpointsMaintenancedata busRMS data busLocalparameterstoragesLocalKeyboard/DisplayModemNM7050RMS systemRMM systemLocalRemoteRMM programModemprogramRMM HBK783-1

©1999 Navia Aviation AS 21464-5 AntennaUSER MANUALNORMARC 7050MARKER BEACON6-156 AntennaNormarc supplies single and dual antennas, NM 3561 and NM 3562 respectively. The single antenna may be used for inner, middle and outer marker, while the dual antenna is specially designed for outer markers. The advantage of the dual antenna is a lower spread in FLYING THROUGH TIME inside the localizer coverage area. In addition to two antenna elements, the monitor and distribution network DI 726 is included in NM 3562. Figure 6-1 Antenna block diagramFigure6-2 shows the field strength of the radiated signal directly above the middle marker antenna. Figure6-3 and Figure6-4 illustrate the field strength above the outer marker antenna, using single and dual antenna, respectively. The localizer course sector is scetched. Along an elliptical curve, the field strength is constant. If you look at the diagrams as ordinary geographical maps, you will see that the dual antenna "field-strength-mountain" is steaper and more stretched sideways than the single antenna "mountain". This corresponds to a sharper on/off response on the aircraft's marker beacon instruments.SINGLE ANTENNA SYSTEMNETWORKDI 726RF OUT RF INDUAL ANTENNA SYSTEMRF OUT RF IN5050HBK914-1

The performances og the antennas con-form to ICAO Annex 10 item 3.1.6, and are such that they are largely independent of environment factors such as rain, snow and ice, and they can therefore be located at «diffi-cult» sites. The directivity of the antennas can, if required, be even further increased by add-ing additional elements to the array.The radiation patterns for the antennas are almost unaffected by the surrondings, and the antennas are therefore suitable for offset location where tilting of the antennas is necessary in order to obtain the required signal coverage. (Refer to figure A-1)Figure12-3, 12-4 and 12-5 shows constant field strenght lines through points in the glide path (GP angle 3º). The marker beacons are located vertically beneath the localizer course line at distance of 1050 m (middle marker) and 3.9 nautical miles (outer marker) from the threshold. The field strengths specified are relative to the maximum level directly above the antenna. The figures show that for an aircraft travelling at a speed of 50 m/s (96 knots) within the maxi-mum allowable course sector of 6º the duration of the visual indication will be within the pre-scribes limits. The instrument panel lamp should be adjusted so as to switch on or off at the levels indicated in the figures i.e. -27 dB to -33 dB for Figure12-3, -11 dB to Figure12-4, and -13 dB to -25 dB for Figure12-5.The marker beacon antennas are mounted on poles, with the dipoles parallel to the course line. The rear end of an antenna should be at least 2 metres above the ground.The NM 3562 antenna comprises two elements, and is fed via a distribution network (DIA 726) which splits the transmitter power into two equal parts. The network is a coaxial cable hybrid housed in silumine box together with the monitor network which is used to combine the signal from the two monitor probes.
