TEX30LCD/S ELETTRONICA 4. General Description The TEX30LCD/S, manufactured by R.V.R. Elettronica, is an exciter for Frequency Modulated audio broadcasting in a frequency modulation able to transmit in the band between 87.5 and 108 MHz, in step of 10 KHz, with an RF output power adjustable up to a maximum of 30 W into a 50 Ohm standard load. The unit is factory aligned and calibrated at the time of manufacture. Because of this manufacture process, there is no field tune-up or alignment necessary.
TEX30LCD/S ELETTRONICA The RF power section of the TEX30LCD/S features a MOSFET module delivering up to 30W output power. Operating frequency stability is ensured by a temperature-compensated reference oscillator and is maintained by a PLL (Phase Locked Loop) system. The exciter will go into frequency lock within 30 seconds after power-on. The TEX30LCD/S can operate throughout the frequency bank with no need for calibration or set-up.

HOT COLD In alternative is cooled by forced ventilation and the air outlet is located on the roof of machine. Is recommended a length of tube approximetively of 1,5 meter. HOT COLD User Manual 50cm Rev. 2.
TEX30LCD/S ELETTRONICA HOT Is highly recommended to install the rack at least 50 cm from the rear and side wall so as to allow an optimum air flow and to facilitate workers. 50cm COLD 50cm 5.1.2.1 Rack power supply connections Provide for the following (applicable to operating tests and putting into service): √ Mains power supply full range 80 ÷ 260 VAC full-range for TEX30LCD/S, both with adequate earth connection.
TEX30LCD/S ELETTRONICA L N PE If transmitter require three-phase power with 3F ������������������������������� (black, brown and grey) + N (blue) + GND (green yellow)��������������������������������������������������� , keep in mind this requirement to connect to your distribution board. R S T N PE Note: the mains must be equipped with adequate earth connection properly connected to the equipment. This is a pre-requisite for ensuring operator safety and correct operation.
TEX30LCD/S ELETTRONICA 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 distribution board of the transmitter is set to “OFF”. 5.1.3 Device power supply connections Provide for the following (applicable to operating tests and putting into service): √ Mains power supply full range 80 ÷ 260 VAC full-range for TEX30LCD/S, both with adequate earth connection.
TEX30LCD/S ELETTRONICA Note: to ensure both the safety of the operators and the correct functioning of the apparatus, it is essential that the network system is grounded, and that it is properly connected to the equipment. Useful tips for a correct connection: 5.1.4 • Provide an adequate grounding of the electrical system.
TEX30LCD/S ELETTRONICA capable of dissipating the power generated by the amplifier. To begin with, set exciter to minimum output power and switch if off. Connect the amplifier INTERLOCK OUT output to the matching INTERLOCK IN input fitted on all R.V.R. Elettronica exciters as standard; if your exciter is a different brand, identify an equivalent input. Connect the RF output to an adequately rated dummy load or to the antenna. Figure 5.
TEX30LCD/S ELETTRONICA persons should maintain a minimum separation distance of 109.25 cm for general uncontrolled exposure and general controlled exposure. RF Exposure Limits for Canada, according to IC regulation: setting to the maximum of the output power of the apparatus, to guarantee the limits of exposure declared within this document, it is necessary that the antenna gain used with this device should be 0dBi or less and all persons should maintain a minimum separation distance of 135.
TEX30LCD/S 5.1.5.4 ELETTRONICA Output power level control Note: The exciter incorporates Automatic Gain Control (AGC) and output power is modulated based on the power level set by the user and actual operating conditions, such as temperature, reflected power and other parameters. Please read section 5.3 for more details of RF power modulation. Access the Power Setup Menu pressing the following keys in the order: ESC (opens Default Menu) ⇒ ENTER (hold down for 2 seconds).
TEX30LCD/S ELETTRONICA When setting input sensitivity, please consider that the default menu reports instantaneous modulation level and an indicator provides a 75 kHz reading. To ensure correct adjustment, apply a signal with the same level as user’s audio broadcast maximum level and then adjust using the trimmer until instantaneous deviation matches the 75 kHz reading. To set subcarrier input levels, you may use the same procedure and option “x10” available in the Fnc menu.
TEX30LCD/S ELETTRONICA The screen that is shown is similar to the following�: Menu 2 NOTE: It is advisable to write down the password set, if you forget the password it is not possible to recover it automatically. To recover the password, contact Customer Service by sending the alphanumeric PUK code of 6 characters generated automatically when entering the password. 1c) To modify power level setting, hold down the ENTER button until opening the power setup menu.
TEX30LCD/S ELETTRONICA If PWR is set to OFF, i.e. power output is disabled, move cursor to PWR. Press ENTER and label will switch to ON, i.e. power output is enabled. Press ESC twice to go back to the default menu (menu 1). 3) Fine tune power setting from menu 2 (see description of item 1b) until achieving the desired value. WARNING: Equipment is capable of delivering more than rated output power (30 W for TEX30LCD/S); however, never exceed the specified power rating.

TEX30LCD/S ELETTRONICA 7. Working Principles 7.1 Panel board The panel board contains the microcontroller (PIC18F452) that implements the equipment control software, the display and the other components needed to interface with the user. The board is connected with the other machine modules, both for power supply distribution and for the control and measures. 7.
TEX30LCD/S 7.3 ELETTRONICA Telemetry board This board is designed to inform the user of the equipment operation state. All input and output signals are available on the DB15 connector. The same board also features the “INTERLOCK” BNC connector for disabling the device. By grounding the central pin, the output power is reduced to zero until the connection is removed. When an R.V.R. amplifier is used, this connector is linked to the power amplifier REMOTE or INTERLOCK by means of a BNC-BNC connection.
TEX30LCD/S ELETTRONICA 7.6 Control Board The main function of this board is to check and correct the MOSFET polarization voltage of the RF amplifier section. It also provides the measurement of the absorbed current and contains a circuit for signaling power supply unit faults. If no alarms are present, the voltage is adjusted only depending on the set output power, with a feedback mechanism based on the reading of the power really delivered (AGC).
