5. Quick guide for installation and use
This section provides a step-by-step description of equipment installation and
conguration procedure. Follow these procedures closely upon rst power-on
andeachtimeanychangeismadetogeneralconguration,suchaswhenanew
transmission station is added or the equipment is replaced.
Oncethedesiredcongurationhasbeensetup,nomoresettingsarerequired
for normal operation; at each power-up (even after an accidental shutdown),
the equipment defaults to the parameters set during the initial conguration
procedure.
The topics covered in this section are discussed at greater length in the next
sections, with detailed descriptions of all hardware and rmware features and
capabilities. Please see the relevant sections for additional details.
IMPORTANT: When conguring and testing the transmitter in which the equipment
is integrated, be sure to have the Final Test Table supplied with the equipment ready
at hand throughout the whole procedure; the Final Test Table lists all operating
parameters as set and tested at the factory.
5.1 Preparation
5.1.1 Preliminary checks
Unpack the transmitter and immediately inspect it for transport damage. Ensure
that all connectors are in perfect condition.
The main fuse can be accessed from the outside on the rear panel. Extract the fuse
carrier with a screwdriver to check its integrity or for replacement, if necessary.
The following fuses are used::
TEX1002LCD
@ 230 Vac
MAINS FUSE (2x) F 10A type 6x30
Table 5.1: Fuse
The mains power supply unit is the full-range type and requires no voltage
setup.
Provide for the following (applicable to operating tests and putting into service):
√ Single-phase 230 (-15% / +10%) Vac mains power supply, with adequate earth
connection.
10 / 26 User Manual
Rev. 1.0 - 22/08/14
TEX1002LCD
√ For operating tests only: dummy load with 50 Ohm impedance and adequate
capacity (minimo 1000W per TEX1002LCD).
√ Connection cable kit including:
• Mains power cable.
• Coaxial cable with BNC connectors for interlock signal connection.
• RF cable for output to load / antenna (50 Ohm coaxial cable with standard 7/8”
connector).
• Audio cables between transmitter and audio sources.
5.1.2 Connections
Connect the RF output of the transmitter to the antenna cable or a dummy load
capable of dissipating transmitter output power. To begin with, set transmitter to
minimum output power and switch it off.
Connect the transmitter INTERLOCK IN input to the matching INTERLOCK OUT
outputtted onR.V.R.Elettronica equipmenttoactas hybridcouplers.If your
equipment is a different brand, identify an equivalent output.
Connect the RF output to an adequately rated dummy load or to the antenna.
WARNING: Electric shock hazard! Never handle the RF output connector
when the equipment is powered on and no load is connected. Injury or death
may result.
Ensure that the POWER switch on the front panel is set to “OFF”.
The transmitter has two switches: one is embedded in rear panel and interrupts
all mains power supply of the machine, while the second is on the front panel and
acts by inhibiting the switching power supply of the machine.
Connect the mains power cable to the MAINS connector on the rear panel.
Note : The mains must be equipped with adequate ground connection properly
connected to the machine. This is a pre-requisite for ensuring operator safety and
correct operation.
Connect the audio and RDS/SCA signals from user’s sources to the transmitter
input connectors.

power supply when Automatic Gain Control is running in power supply
limitation mode (please read section 5.3 about RF power supply modulation for
more details).
Note: Output power may be set using the Pwr OFF control. In this condition, the
output power readout (Fwd) on the display will read 0 (zero); the SET bar will reect
any adjustments you make using the keys and provides a graphic indication of how
much power supply will be delivered the moment you return to Pwr On state.
5.2.5 Changing the Power Good alarm threshold
Change Forward Power Good alarm setting PgD from the Fnc menu as desired
(factory setting is 50%).
5.2.6 Setting equipment I2C address
