The Common Point Current, and Tower Light Monicor would
be
assigned to che
data inputs of two OCher channels.
Since there
L5
a
spare channel in the example,
channel
15,
it could be used to input the tower light monitor whi.ch does not require
Raise or Lower Operations.
Remaining unused channels on connectors dedicated to the
Antenna MOnitor must not have their Common Lines used Since these will be connected
to the monitor voltage return when the channel is selected.
Using the momentary contacts provided
in
the RY-15 Relay Interface Unit further
switching of patterns, reference tower, etc., can
be
custom designed.
Such discuss-
ions are beyond the scope of this manual because of che myriad
of
possibilities.
