NON-TECHNICAL PRE-COMMISSIONING
2.2
On delivery of the transmitter, the
following non-technical procedures should be
observed and completed.
NOTE
Non-technical procedures are defined as being those
procedures that do not require technical knowledge
of transmitter circuits or their operation to
complete.
2.2.1 ACCEPTANCE OF SHIPMENT: All
shipments should be inspected for transit damage
prior to acceptance.
Sufficient manpower or mechanical assistance
should be on hand when removing the transmitter
cabinet from its packing crate. The crate may
weigh in excess of 250 kilograms (550 pounds)
2.2.2 UNPACKING INSTRUCTIONS: The
unpacking instructions are dictated by method of
packaging for shipment. Transmitters not shipped by
electronic equipment moving specialists may be
packed in wooden crates, with the number of crates
determined by the extent of disassembly for shipment.
Instructions accompany any crate that requires
special unpacking information. Packing lists provide
detailed listings of shipment contents.
NOTE
The transmitter will be partially disassembled for
shipment. As a minimum, the intermediate power
amplifier (IPA) module, the RF power modules and
the power transformer assembly will be removed.
The extent of any additional disassembly will be
dictated by the shipping method, site information
provided by the user and the handling equipment of
the mover.
2.2.3 ASSEMBLY/INSTALLATION: The
following paragraphs provide step-by-step assembly
instructions for the FM10 transmitter, which is
partially disassembled for shipment.
NOTE
Partially disassembled transmitters should be
placed in their final location prior to completing
assembly.
2.2.4 INSTALLATION OF EXTERNAL
CONTROL/MONITOR WIRING: Connect
wiring originating from the remote control/monitoring
devices to terminating points on control/monitor
PWB A14, as follows:
NOTE
Remote control and remote monitor wiring
terminate on the control/monitor PWB (A14). Refer
to figure MD-2 as an aid to locating the control/
monitor PWB and to its service instruction manual
as an aid in locating terminal blocks TB1/TB2. The
terminal blocks will accept wire sizes #14 through
#24.
The user must punch out an appropriate sized cable
entry hole where the control/monitor cables enter
the cabinet. The preferred entry point is the top left-
hand side of the cabinet. Refer to figure MD-15 to
determine the recommended cable entry location.
(a) Punch or verify a cable entry hole for the
control/monitor wiring has been punched in the
cabinet at the desired cable entry point.
(b) Obtain four 38mm ferrite toroids (LXP38)
from the ancillary parts kit.
(c) Route control and monitor wires; through cable
entry hole determined in step (a), to the vicinity
of the control/monitor PWB (A14).
(d) Pass all control/monitor wires, including their
shields, through two ferrite toroids. The wiring
to TB1 should pass through one pair of toroids
and the wire to TB2 should pass through the
other pair. If practical, the wires should pass
through a minimum of two times (two turns).
(e) Using figure 2-1 as a guide, determine the
specific destination of each wire.
(f) Cut each wire to the required length and remove
approximately 3/8" of insulation from the end
of each conductor.
(g) Insert the control/monitor wiring into the
terminals of the control/monitor PWB (A14)'s
TB1 and TB2, as identified in figure 2-1.
Ensure their securing screws are firmly
tightened.
