1 General information
General information
1.1 Intended use
The products described in this document are solid state transmitters with an output
power adjustable from 0W up to the maximum rating (see “Family variants“ section),
using in FM band between 87.5 and 108MHz at 10kHz steps.
The Indium series, this is its name, that already stands for new lines, new colors, an
innovative look, and especially new technology designed to outstanding performance,
has been further improved.
More compact size, weight not exceeding 10kg, with an extension of output power
maximum range (up to 2000W).
The RF performance, obtained with a number of modules from 3 to 1 depending on the
model purchased, are close to the finish line that is not superable in terms of efficiency,
with devices and technologies of today.
Thanks to these features, ETG series allows a drastic electricity costs reduction.
The product distinguishing features remain : ECOSAVING, ICEFET, VSWR PEAK HOLD, moni-
toring capability, protection against corrosion.
The options would satisfy all needs : MPX, STEREO or AES/EBU versions; TC/TS, TC/
TS+ETHERNET+PROFILES options; LIFEXTENDER.
1.2 Shipment
The shipment may only be performed in its original packaging.
However, although this is designed to avoid product damages, even in mishandling
case, it is recommended to respect the “UP/DOWN” side and to not give shocks.
To make sure that the type of transport and lifting equipment type are capable to sup-
port the weight.
1.3 Unpacking
The staff, handling the product, should operate with gloves and shoes against injury.
Before lifting or handling equipment to verify that you have done to clear the area
of operation, considering a safety area large enough to avoid damage to persons or
objects that may be in the range of maneuver.
1.4 Storage
If you wish, for whatever reason, store the product it is necessary that:
• the temperatures, in the storage, are not exceeded -20 ° - +55 ° C, with humidity
not exceeding 90% at 55 ° C;
• the equipment must be disconnected from the sources of energy;
• the equipment is clean and there are any dust;
• the equipment is covered with a waterproof sheet.
10 General information
1.5 Off line and disposal
For all aspects concerning the product disposal, reference should be made the specifica-
tions required by European Directives.
However, please note that the equipment DOES NOT CONTAIN OILS POLLUTION.
1.6 Purchased product verification
Please note, before installing the equipment, to verify that it has not been damaged
during transportation or storage conditions.
Check that all standard components and accessories ordered have been delivered cor-
rectly, and if not please contact Elenos for material adjustment.
In this case the package must contain at least :
• n°1 Indium series product;
• n°1 “Identification and Quick Start” manual, which should be kept at station, always
attached to the product;
• n°1 “User” manual.
Cables, spare parts and other accessories can be obtained by Elenos or Elenos dealers.

2.3 Protections
The device has a protection system, partly integrated and partly optional, related to har-
dware and software.
2.3.1 Software protections
2.3.1.1 IPF (Intelligent Proportional Foldback)
IPF is an intelligent system that reduces the output power in case of unbalanced load
avoiding shutdown.
On the display the activation of this mechanism is manifested by the “026” alarm.
2.3.1.2 IPC (Intelligent Power Control)
The IPC shall, under proper operation, to maintain constant output power by +/-1% of
target set, independent of changes in voltage, temperature or load.
This contributes largely to make the apparatus insensitive to the conditions in which he
is forced to operate.
The IPC also helps to optimize the RF efficiency, leading the MOSFET to work at maxi-
mum efficiency, minimizing the total power consumption.
2.3.1.3 Safety Management (option Lifextender ®)
The Safety Management is a set of algorithms that perform real-time analysis of tran-
smitter functional state and operates to maintain the output power provided, depen-
ding on the type and extent of any anomalies (internal or environmental) to be arise.
The Safety Management can command a reduction in output power depending on the
anomaly seriousness that has occurred.
The algorithms operate at different levels and in different sections of the apparatus:
Thermal Management on RF group, Current Management on power supply, Thermal
Management on power supply, Fault Management on RF group, Fault Management on
power supply, Cooling Management on fans group.
Thermal Management on RF group (Lifextender ®)
If the temperature measured at the MOSFETs exceed the value of 72 ° C it involves an
initial level of Derating, operating to reduce the temperature by reducing output po-
wer. The power reduction is the minimum possible to reach a thermal equilibrium at a
temperature below 72 degrees. The reduction of output power, with this first derating,
never exceeds 48%. In other words, the output power remains above 52% of that set
by the user, and it does not activate “- 3 dB” alarm.
This first level of Derating is effective in almost all cases.
On the display the activation of this mechanism is manifested by the “010” alarm.
If this Derating is not enough (very rare), it involves a second level that, reducing the
power, reaches a state of thermal equilibrium compatible with the safe operation of the
device, even if under - 3 dB (“005” alarm).
In case of ineffectiveness also of this second derating (case of external conditions that
are not compatible with the safe operation of the apparatus) the transmitter is turned
off. In this case, if the temperature drops, the power is raised proportionally. If it chan-
ges by 10°C (that goes to 62°C) it leaves the mechanism of derating and resumes full
power. After three unsuccessful attempts, the control logic blocks the apparatus (“011”
alarm).
Current management on power supply (Lifextender ®)
It is activated when it exceeded the maximum current for continuous operation of
power supply. This value is set below the limit of output current, and it represents the
