1.1.3 Marker Beacons Description

The marker beacons are located verticall y beneath the localizer course line at distance 150m (inner marker), 1km (middle marker) and 7km (outer marker) from the r unway threshold.

The beacons radiate a 75MHz radio signal with an audio Morse code. The Morse code and modulation frequency diffe r for the outer , middle and inner marker. Outer marker transmit s dash code 400Hz, middle marker transmits dash dot code 1300Hz an d inner marke r dot code 3000Hz.

1.2 Product Type Numbers

The Normarc product numbering system is based on the following three levels:

•System

3.2 Transmitters / Modulators

The NM7050 consists of two TX1373A transmitters. The main transmitter is connected to the antenna, while the standby transmit ter 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 ma inly by a Field Programmable Gate Array (FPGA). A strap field selects Inner, Middle or Outer Marker settings.

An onboard oscillator generates a 75MHz carri er wave whi ch is amplit ude modul ated wit h the

21464-5

USER MANUALNORMARC 7050

MARKER BEACON

audio signal in the Power Amplifier (PA). The PA is capable of delivering up to 4W power at 97% depth of modulation.

Unwanted frequencies are removed by a lowpass filt er 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 Systems

The 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 possibiliti es for longer backup time. This battery is automaticall y brought into circuit on mains power fail ure. The charging time is approximately eight hours with one PS1375 and five hours with two PS1375.

3.5 Remote control system

The remote control unit is used in the tower or in the technical control room. It has indicators for operating status as well as det ailed 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.

3.6 Remote Maintenance Monitoring (RMM)

The NM7000 series has a built-in Remote Maintenance Monitoring system. This system consists 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.

The centre of the RMM system is a CPU with the RMS core program. The RMS col lect s measurements and diagnostic data, and makes them available to the user. The collected information allows easy and cost effective ma intenance, fault finding and routine reporti ng. 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, typi cally used to connect a local PC and a connection to a central maintenance facility.

21464-5

USER MANUALNORMARC 7050

MARKER BEACON

The local keyboard/display all ows readi ngs and control s thr ough an LCD displa y and a sevenbutton keypad. This gives access to the RMM functionality without the need for a PC.

3.7 RMM Access

Access to the RMM system is controlled by multiple hardware and software access controls. One password is required for each access le vel, i.e. one password for level 1, two for level 2 and three for level 3. Optional hardware controls may inhibit writing in the upper access levels.

Access level 1

• Readout of all the monitor values, warning and alarm limits.

• Readout of all the maintenance values and warning limits.

• Readout of all the delays.

Access level 2

• TX1 and TX2 : morse normal, continuous or off.

• TX1 and TX2 : test signals 50% depth of mod. and 50% RF level.

• Diagnostics.

Access level 3

• Settings of all the monitor warning and alarm limits.

• Settings of all the maintenance warning limits .

• Settings of all the delays.

3.8 Storage Functions

The RMS has the following storage functions:

Alarm Storage:

8 alarm logs can be stored. One log consists of a CURRENT LOG and a HALF MIN LOG. Current log is a continuous 2 seconds log of monitoring and maintenance parameters. Half min log is a 30 seconds log of monitoring and maintenance parameters sampled at 5 second intervals. A log is stored when a SHUT-DOWN or CHANGE-OVER alarm occurs.

Periodic Storage:

Stores 16 data sets of monitored data on configur able periodic intervals.

Event Storage:

Stores t he last 50 even ts. Each event is stored with a TIME_STAMP and a USER_ID (of the user executing the command). Stored events are; change in WARNING and ALARM states, excution of S logout from access level 3, SYSTEM ADMINISTRATION, and log-in and log-out at access level 2 and 3.

TATION CONTROL COMMANDS, changes in WARNING and ALARM LIMITS on

3.9 Local Keyboard/Display Functions

Through a menu based interface all main commands, adjustments and monitor limits are accessible from the front pane l keypad and LCD display. In addition a quick read function gives readout of all main monitor pa rameters at a glance.
