manufacturer's standard, unless otherwise indicated. Damaged surfaces
shall be repaired and refinished using original type finish. A sealed
viewing window on each enclosure's door shall correspond with the Contact
Position and Test LEDs location. An integral 19 mm 3/4-inch threaded
nipple shall provide a weatherproof interface with associated exterior
conduit or enclosure. The hinged door with latch shall have a provision
for a utility meter seal.
2.6.8
Nameplates
Nameplates shall have unique identifiers engraved or stamped. Permanently
attach nameplates to enclosure panel doors and back plates. For each field
mounted piece of equipment attach a plastic or metal tag with equipment
name and point identifier.
2.7
FIELD TEST UNITS
**************************************************************************
NOTE: Design must specify what field test unit is
needed.
**************************************************************************
Field test units may be separate or combined as one unit. These units
shall be provided to accomplish the following requirements:
a. Portable Test Unit (PTU) shall be used to exercise and test the
proper operation of a load control receiver by using any of the RCS's
operational address function commands. The PTU shall transmit a 7.5
minute time-out and 7.5 minute cycle time message to the unit. The PTU
also provides cancel commands for all function commands.
b. The Portable Counter Display (PCD) shall read the RCS's internal
memory register by placing it over the RCS's viewing window. The PCD
verifies internal addressing, operations counts, and the RCS's serial
number.
c. The Remote Transmission Monitor (RTM) is used to receive FM-radio
control messages from the broadcast frecuency that the Load Management
system is using. The RTM deciphers the message and feeds it back to
the Load Management system for a closed loop verification of messages
transmitted. Normally one per system is all that is needed on bases.
d. The Field Strength Unit (FSU) shall determine the location that will
give the best signal strength for the load control receivers to be
installed.
2.8
ANTENNA SYSTEM
**************************************************************************
NOTE: The designer must show the topography on the
drawings.
**************************************************************************
The antenna system shall utilize vertically polarized antennas, coaxial
cable between transmitters and antennas, and matching networks required for
the proper coverage. The antenna system shall be either omni-directional
or shaped coverage as determined by the Contractor from the topography.
The antennas shall be capable of withstanding the environmental conditions
of [200] [_____] km/h [125] [_____] mph wind and [13 mm 1/2 inch radial]
