Either monitor alarm initiates station transfer
Hot standby transmitter monitored
Cold standby transmitter
Field monitoring enabled
Field monitoring disabled
Field monitor has executive control
Field monitoring does not have exec. control
Station shutdown if communications with
RSCU/RSCE is lost (includes LCP if remote
communication is through that: SW2/5 open)
Station maintains same operation if commu-
nications lost to LCP or RSCU/RSCE.
DME shutdown when interlock signal re-
moved (DME remains on even if the ILS is
alarmed off or turned off by the user for
maintenance or such).
DME shutdown when the on−antenna trans-
mitter is shutdown
(DME is on only if ILS exec. TX is on).
