FM10
Page 2-7
01 October 2002
2.1.11.2 RF On Status: The RF On Status output
is applied to
RF ON STATUS
terminal TB2-9 of the
control/monitor PWB (A14). When the external
interlock is open or a local or remote
RF OFF
has
been initiated, this output is an open collector. When
the interlock circuit is intact and a local or remote
RF
ON
has been initiated, the
RF ON STATUS
output is a
current-sink-to-ground.
2.1.11.3 Transmitter Ready Status: The XMTR
Ready Status output is applied to
XMTR READY
terminal TB2-10 of the control/monitor PWB (A14).
When the AC/DC power supply is not producing a
reg5V (no unregulated 24 V) and the control
functions are not operable, this output is open
collector. When the AC/DC power supply is
producing a reg5V, and control functions are
operable (locally or remotely as appropriate), the
XMTR READY
output is a current sink to ground.
2.1.12 PARTS SUPPLIED BY NAUTEL: The
following parts/materials are supplied by or are

2.1.12.2 Ancillary Parts: An ancillary parts kit is
provided with each transmitter. These parts are
provided to ensure initial installation is not delayed
because of a lost or damaged part and to allow the
user to maintain the equipment until a comprehensive
maintenance spares kit is obtained. They are not
intended to be long term maintenance spares.
Detailed information about these parts is not included
in this manual. The ancillary parts kit contents is
itemized in its packing list.
2.1.13 PARTS REQUIRED BUT NOT

normally include the following:
- A suitable 50-ohm RF output coaxial cable,
terminated by a 3 1/8 inch EIA connector, with
inner conductor, at the transmitter end.
- All external control/monitor wiring, including
their associated terminating devices and
conduit/conduit clamps.
- All electrical power cables, including conduit,
terminating devices and conduit clamps.
2.1.13.1 Surge Protector Panel: A surge protector
panel, that is rated for the AC power source to be
applied to the transmitter, is available from Nautel.
The surge protector panel will help protect the
transmitter against lightning induced voltage
transients on the AC power source.
2.1.14 TEST EQUIPMENT AND SPECIAL
TOOLS: The test equipment required to install and
maintain the transmitter is listed in table 1-2 and the
special tools are listed in table 1-3.
