• Some components contain TOXIC SUBSTANCES, including BERYLLIUM OXIDE. Be care­ful because some countries may have rules governing the storage and disposal of
dangerous materials.

• If after an inspection some component is damaged or broken, you must proceed
with caution to any physical contact with hands or otherwise.

• You must ensure that any person who uses a transmitter with dangerous voltage
knows artificial respiration and cardiac massage, and you must train users on first
aid in case of need. In station with electrical equipment you should hang in a visible
position instructions of the phases of assistance to persons involved in an accident
and equip the station of a first-aid kit. It is advisable to have a plan of action for

3.3 Station features

3.3.1 Environment features

To be able to operate freely on the equipment and be able to make installation or
maintenance it is necessary to maintain a minimum distance from the walls on each
side of the machine.

The room must be equipped with an adequate fresh air and filtered from dust, with
adequate capacity with the characteristics of the equipment working in space.

The output exhaust air must be conveyed directly to the outside.
If the size or the duct length are such that assume a significant air flow drop it is neces­sary to add an extraction device.
At the conveyor exit shall be provided devices against intrusion (compared to insects
or other animals) and precautions should be taken to prevent entry of liquids or other
materials.

The device can operate properly if the temperature is between -5 °C to +45 °C, with
relative humidity to 95%, non-condensing to +40 °C.

3.3.2 Wiring features

The mains system shall be in accordance with all current rules. The power supply should
enable to provide adequate power in accordance with regulations of the installation
country about the service quality of electricity supply.

It’s recommended the use of a network isolating transformer and of an energy reduc­tion network for high voltage discharges.

Provide a protected switchgear (circuit breaker or fuse) with breaking and flow properly
related to the device absorption characteristics.

Use cables properly sized related to current input.

17Security

The earth connection must be implemented according to current standards. Particular
attention must be used to grounding of the antenna system, because it is exposed to
atmospheric electrical phenomena.
Remember that despite the ground link it is always dangerous to operate on the
apparatus in case of bad weather, with the presence of lightning; in fact, because of
inductance ground connections it is possible, in case of high energy discharge, that the
apparatus reaches dangerous instantaneous levels of voltage.
It is, therefore, appropriate that the equipment is installed in accessible area only to
maintenance people and only for the time necessary to repairs and inspections.

5.6 Protections

The device has a protection system, partly integrated and partly optional, related to har­dware and software.

5.6.1 Software protections

5.6.1.1 IPF (Intelligent Proportional Foldback)

IPF is an intelligent system that reduces the output power in case of unbalanced load
avoiding shutdown.

5.6.1.2 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 maxi­mum efficiency, minimizing the total power consumption.

5.6.1.3 Safety Management (option “Lifextender”) ®
The Safety Management is a set of algorithms that perform real-time analysis of tran­smitter functional state and operates to maintain the output power provided, depen­ding 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 po­wer. 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 40%. In other words, the output power remains above 60% 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.
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 (the alarm is forwarded).
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, THERMAL DERATING provides a hysteresis of 10 ° C before restore the ap­paratus to normal operation. After three unsuccessful attempts, the control logic block
apparatus.

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
threshold that can be exceeded for short periods (up to 1 minute each time).
If this condition occurs, it is enabled “PSU current derating” and ALC management algo­rithm to normal operating condition is replaced by another in which the VDS and Bias
control is given by power setting and, with even higher priority, by the current supplied

32 Product description

from power supply.
The condition of current derating is turned off when the power supplied back to the va­lue set by the user and if the maximum current supplied from power supply is less than
or equal to the maximum allowable value for continuous operation.

Thermal management on power supply (Lifextender) ®
The algorithm of power supply management, function of temperature, is the same as
that in the RF group, and is connected logically “OR” to it.
The first level of Derating (which acts directly on the output power) is activated when
the power supply temperature exceeds 75 ° C, while the second level is activated if,
with the first ineffective, the temperature is not stable below this value. In this second
case the output power is brought below the - 3 dB, with the same procedure already
described in RF section.

Fault management on RF modules (Lifextender) ®
It makes the maximum output power management depending on the number of RF
amplifier modules being properly operated.
If one or more MOSFETs are considered failed (this happens when the current consum­ption is less than 10% of the average), RF output power is reduced to the expected
value in the presence of failure experienced. The failure case histories and maximum
power achievable are described in a complex table obtained through experimentation,
and are designed to stop MOSFETs failure, that are still operating, by avoiding that are
overly stressed by the mechanism of ALC (which would call these to supply the power
output missing).
To avoid an unnecessarily large number of alert SMS, during this stage are not sent: any
alert SMS, if validated, will be sent only after the output power adaptation procedure,
according to the parameters table, and only if -3dB condition is verified.

Cooling Management on fans group (Lifextender) ®
The fan speed is adjusted, depending on the actual cooling needs, from a minimum of
60% to a maximum of 120% (these values may differ by different models of fan used).
The cooling need is estimated on the basis of accurate temperature measurements
that are made on RF MOSFETs and on power supply. The Cooling Management aims to
extend the lifespan of the fans, to minimize the amount of dust that can be carried by
the airflow, and to guarantee a safe operation of the apparatus, even under extreme
conditions of temperature.

5.6.2 Hardware protections

The hardware protection system includes:

• fast electronic and fuse protection on power supplies;

• fast electronic protection on fans power supply ;

• fast protection against excessive reflected power (ROS/VSWR), caused by a strong
mismatch of the load. This protection occurs when the value of reflected power
exceeds 10% of the direct power.

7.2 Alarms/events list

There is an “Alarms Management” module.
To check the alarm conditions physical and logical digital inputs are used.
Each input status is sampled and then the condition is logically drawn by a combinato­rial network, to define if the alarm or signal are active.
Response time is 100ms minimum.
This module is repeatedly performed with the same priority as the ALC management, in
order to constantly monitor the occurrence of alarm causes, and thus to operate in good
time.

7.4 Optional equipment can be connected

ETG may be connected externally to the following units:

• PC;

• TELEMETRY;

• EXCHANGE UNIT and/or AUDIO MATRIX UNIT;

• AMPLIFIERS.

7.4.1 PC connection

This connection is useful to examine in detail the operating parameters, for example
during the performance evaluation or repair activities.

To PC connection an interface cable must be inserted into the “Interface” connector,
DB9, on the front panel of the machine.
This cable ships with the product.
To details on the pin out see “External connectors description” paragraph in “Product
description” section.
The link may also be a machine running.

For viewing it’s sufficient Windows HyperTerminal program.
You must activate Hyperterminal from “Programs” -> “Accessories” -> “Notifications”, or
other equivalent program available. From the “File” menu select “Properties.”

In the mask opens you select the port from which to communicate (in the current
example is COM1), then press the Configure button to enter in the settings screen. The
parameters to set are: 9600 bits per second, 8 data bits, no parity, 1 stop bit, no flow
control.

65Use instructions

To Verify that the other masks on Hyper Terminal contain the settings as below. Confirm
by pressing the “OK”.

At the end, activate the connection by pressing the Call button.

To communicate with the equipment you need to make a final step, to put the address.
This step is crucial because each device, to be queried and managed remotely, must be
properly addressed. In this case, the following alpha-numeric sequence must be put: 2
1 i x x. With xx the address of the machine.
If the machine is in local mode you can only see data, if the machine is in remote mode
you can also set the parameters directly from the PC.

7.4.2 Telemetry connection

This connection allows remote control through the equipment specifically designed
for that purpose. The telemetry unit provides backup energy for the continuous opera­tion of the modem, and is equipped with all utilities for equipments and station para­menters supervision.

To telemetry connection a cable must be inserted into “EIA485” connector, DB9, on the
rear panel of the machine.
This cable ships with telemetry unit.
To details on the pin out see “External connectors description” paragraph in “Product
description” section.
The link may also be a machine running.
For more information, please see “Telemetry” manual.

7.4.3 Exchange unit and/or Audio matrix connection

This connection allows to use the transmitter in a system that exchanges a fault trans­mitter failed with a reserve.

To exchange unit connection, if the equipment is not a reserve, a shielded cable must
be inserted into “TC/TS”, DB25, on the rear panel of the machine.
If the device is a reserve to use an additional shielded cable to insert in “Profiles” con­nector, DB25, in the rear panel of the machine.
This last cable will connect to the audio matrix, if there is an audio matrix.
These cables ship with the unit of exchange.
To details on the pin out see “External connectors description” paragraph in “Product
description” section.
The signal link may also be a machine running, no the RF link.
For more information, please see “Exchange unit” manual.

7.4.4 Amplifier connection

This connection is where you need to increase the power transmission using a RF power
amplifier.

To use the ETG as an exciter of a higher power amplifier to connect the ETG RF output
connector to amplifier RF input connector through a RF coaxial cable, which is capable
of withstanding the maximum power of ETG. In addition to the RF connection, should be
included a cable to insert in TC/TS connector, DB25, on the rear panel.
This cable ships on demand and it’s important check exciter functionality of the in the
case of amplifier protection (eg exciter shutdown in case of ROS / VSWR amplifier pro­tection).
To details on the pin out see “External connectors description” paragraph in “Product
description” section.
Warning : to RF connection the machine must be turned off.
For more information, please see “Amplifier” manuals.
