6.3.2 Monitor Integrity Check (Alternative 1)
6.3.2.1 False radiation time Tx1 Main
Equipment in mode AUTO. Main Select Tx1. Tx 1 on.
• Remove the CL monitor cable from the monitor input.
• Note the time elapsed*) from the signal was removed until Tx2 was shut off.
• Record in Table 6-9 line
a
) the measured delay time from cable removal until the standby
transmitter has switched off. Check that the equipment carries out a changeover to Tx 2
before shutoff. Record in Table 6-9 line b)
• Open PA maintenance parameters window. (Ref para 5.7.5 Operating Manual). Check that
PA 27V LEVEL Course Tx1 is 0 V. Record in Table 6-9 line c).
Reconnect the monitor cable.
6.3.2.2 False radiation time Tx2 Main
Equipment in mode AUTO. Main Select Tx2. Tx 2 on.
• Remove the CL monitor cable from the monitor input.
• Note the time elapsed*) from the signal was removed until Tx1 was shut off. Check that the
equipment carries out a changeover to Tx 1 before shutoff.
• Record in Table 6-9 line
d
) the measured delay time from cable removal until the standby
transmitter has switched off. Check that the equipment carries out a changeover to Tx 2
before shutoff. Record in Table 6-9 line e)
• Open PA maintenance parameters window. (Ref para 5.7.5 Operating Manual). Check that
PA 27V LEVEL Course Tx1 and Clearance Tx 1 is 0 V. Record in Table 6-9 line f).
Reconnect the monitor cable.
Note:*)
Near immediate change if short delays are used.
6.3.3 Monitor Integrity Check (Alternative 2)
Can be performed from a remote location.
Test equipment
• PC with RMM
Note results in
Table 6-10 (Alternative 2).
6.3.3.1 Integrity check:
Open the RMM program in
level 2
.
Note: Level 2 must be enabled for the remote RMM in the ILS configuration.
• Tx1 to antenna. Use MAIN SELECT and CHANGEOVER in the Front Panel window.
• Open Front Panel, Event List, Ident and Modulation Switches and Maintenance Win-
dows for COURSE TX1 LPA/GPA, CLEARANCE TX1 LPA/GPA, COURSE TX2 LPA/
GPA, CLEARANCE TX2 LPA/GPA.
• Turn off Tx1 COU Mod 90Hz in the Modulation Switches window. Observe that a transfer
