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 31). The MO1374 is mainly a microprocessor based module.

USER MANUAL NORMARC 7050 MARKER BEACON The Remote Control Unit is connected to the MB by one pair telephone cable. 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.
PAGE 25
NORMARC 7050 USER MANUAL MARKER BEACON The local keyboard/display allows readings and controls through an LCD display 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 level, i.e. one password for level 1, two for level 2 and three for level 3.

PAGE 55
NORMARC 7050 USER MANUAL MARKER BEACON The software adjustments are most easily done with the RMM program, but may be carried out from the front panel. • This procedure requires that the output power is already adjusted • Set the input attenuation straps on MO1374 according to the marker type. Start out with 22dB attenuation for outer marker, 18dB for middle marker and 12dB for inner marker. • Watch the Monitor parameter RF LEVEL.
PAGE 56
USER MANUAL NORMARC 7050 MARKER BEACON ΤInner Marker uses an external 10 dB attenuator, use 0.2W, 0.1W and 50mW to calibrate. CARRIER POWER is measured prior to the attenuator, but the software will automatically compensate for the 10dB. 7.5.2 Battery protection cut-off voltage The purpose of this circuit is to avoid deep discharge and thereby reduced life time of the backup battery. For normal lead acid accumulators 22V (1.83V/cell) is a reasonable cut-off voltage.

NORMARC 7050 USER MANUAL MARKER BEACON PART V APPENDIX A ANTENNA TYPE NM 3561 / NM 3562 A.1 Antenna NM 3561 / NM 3562 For Ils Marker Beacon The NM 3561/NM 3562 Marker Beacon Antennas are log-periodic dipoles possessing properties of high gain and directivity, and low side lobes. The performances og the antennas conform 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 «difficult» sites.
