Vector-LP Radio Beacon Transmitter Technical Instruction Manual
Issue 1.1
Section 2 Preparation for Use and Installation
2.2.20.1 Standby Side
The Vector-LP transmitter can be upgraded
to accept a standby RF power module and a
set of standby exciter assemblies, including:
x
RF synthesizer PWB (A8)
x
Interphase PDM driver PWB (A9)
x
Exciter monitor/generator PWB (A10)
x
RF power module (A13)
x
Universal input ac/dc power supply (U3)
When the standby side components are
installed, the transmitter must be placed in
NORMAL
changeover mode to enable the
standby switching feature.
2.2.20.2 Spares Kit
A comprehensive maintenance spares kit is
available. The kit includes a quantity of each
through-hole semiconductor, LED, and fuse
used in the equipment as well as important
repair items such as semiconductor
insulators, fan filters, etc.
2.2.20.3 Interface Protection Unit
A surge protector panel rated for the ac
power source being 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 and/or the
antenna system.
NOTE
Figure 2-5 shows the recommended system
installation for a transmitter system. This
drawing emphasizes the interconnections to
the interface protection unit.
2.2.20.4 Battery Backup
If purchased, the battery boost assembly
(A16) will distribute appropriate voltages to
the exciter assemblies and power modules.
When purchased, the battery boost PWB is
used in conjunction with a bank of user
supplied batteries attached in such a
manner as to provide 24 V dc (VR125 only)
or 48 V dc and suitable current to allow the
system to operate in battery backup mode.
2.2.20.5 Site Interface
The optional site interface PWB (A4) mounts
below the remote interface PWB on the back
of the front panel (see Figure 2-2). It can be
used to provide 16 control points and 16
monitor points from a remote location via
terminal block connectors. The active status
of these control and monitor points can be
configured using the front panel GUI.
2.2.20.6 Modem Kit
An optional modem kit (Nautel Part #
195-3032) is available. The kit includes a
Multi-Tech Systems MT5634 modem (Nautel
Part # UW66) and its associated cabling.
The transmitter can be set up for modem
operation in the RCMS section of the front
panel GUI.
2.2.20.7 Deluxe Cabinet Mounting
An optional cabinet (Nautel Part # 205-8075,
see Figures SD-26 and MD-1B) is available.
This cabinet supports the Vector-LP on slides
and also contains:
x
terminal block TB1 to accept the external
ac power source
x
ac line cord (P3, Nautel Part # JN50) to
connect between TB1 and the Vector-LP
x
RF output connector at the top of the
cabinet, and associated coaxial cable
(W1) for connection to the Vector-LP’s
RF output
x
interconnect cabling (see Table 8-6)
x
optional battery charger (U1), which
receives its ac input via TB1
2.2.20.8 IP66 Cabinet Mounting
An optional IP66 cabinet (Nautel Part #
205-8080, see Figures SD-27 and MD-1C) is
available. This cabinet supports the
Vector-LP in a weather-proof cabinet with
accessible weather-proof connectors. An
optional battery charger unit may be installed
on the floor of the cabinet.
