It is advisable to run the first tests connecting the transmitter to a suitable (for type
and power) dummy load rather than to the transmission antenna.
5.2.2 Power-on
When powering-on the transmitter the first time, perform the operations below to
work efficiently in less time as possible.
• Switch on the service mains supply.
• Keeping the exciter at its minumum power level. When power up, the ATVTE exciter display reports the frequency and power
level; if these are not as required, just switch it in OFF mode to temporarily
deactivate the power output.
• Set the CCU unit in manual mode and switch it in OFF mode.
• Switch on the mains power supply for all amplifiers.
• Enable the exciter currently connected to the amplifier and check the working
frequency. If necessary changed it.
• Set the CCU unit in manual mode and switch it in ON mode.
• Rise its output power until the output power of the amplifier (the overall power indicated on CCU unit display) reaches its required value indicated in technical
dossier.
Note: during the RF output power rising, check the reflected power level (on
Control Unit) to verify the antenna status.
The transmitter is now up and running at its nominal power level. It is then possible
to perform all the controls and verification that one thinks are necessary before
putting it into operation.
Also you should check:
• The equipment must be installed in an air-conditioned at 25°C and at room
temperature should not exceed 35°C.
• The hot air coming out from the roof of the rack must be carried out through a
tube with a diameter equal to or greater. If the tube has a length greater than
1 meter, install an exhaust fan on the side that goes out.
• Each rack has its own drawer. These can identify the label indicating the channel,
placed the tray.
• Before turning to make sure that all RF cables are tight and that the return loss
to the antenna is at least 26dB.
• Make sure is present an ASI signal of 270Mb/75Ohm. Check that the bitrate
of the program to be transmit is less than, or equal to, the maximum bitrate in
output.
• To be sure your system is set to start around 10% below the nominal power.
Adjust dall’exciter power during the heating phase (at least 1 hour).

The control unit communicates the nominal
power and reduced power values to the RF
modules. It also handles the coaxial relays
so that the on air exciter is the desired one
and sets the exciter to ON mode
Adhere to the instructions of the exciters
used for setting the required work frequency
on the exciters. Check if the working
frequency is correct, then adjust the power
of the exciters to the minimum. Only after
pressing ON you can adjust the RF power
output slowly increasing it until to reach the
nominal power of about 5W.
Check the emitted power level by means
of the analog instrument with the selector
switched to FWD PWR position. The
power will be viewed on CCU as 50W
instead 5,0W, but this is a detection system
error because the CCU visualization not
integrates the “,” symbol. Always check the
RFL PWR detected.
When the transmitter is on and works at its nominal power, the whole series of
“accessory” checks and settings deemed necessary may be carried out before
starting up the apparatus.

6.4 Management of the exciters
This chapter describes the ways in which the microprocessor controls the amplifier
and how the user may interact with the software.
The control unit can perform the automatic changeover between exciters if one
malfunctions. The Manual LED on the panel indicates, when it is lighted up, that
the automatic changeover function is disabled. In order to enable it, click the
EXCITER CHANGEOVER button and check that the LED turns off. In operation
of the ATUNT5K0AQ & ATUNT5K0AQ1D automatism state, the behavior of the
machine will be different. In this chapter are described the different cases.
In function of the state of the ATUNT5K0AQ & ATUNT5K0AQ1D automatism,
the behaviour of the machine will be various. In this chapter are described the
different cases.
6.4.1 Start-up from power-on with exciters in manual mode
When powering on the machine with the exciters in manual mode, the apparatus
does not perform any check, both mute RF signals are active and the changeover
relay remains in standby status. Use the exciters menu to activate an exciter.
This is why, if the transmitter is left in manual mode, any momentary power failure
will cause the transmitter to be inactive when turned on again. Therefore it is
advisable to leave the ATUNT5K0AQ & ATUNT5K0AQ1D in automatic mode
when you are not performing maintenance operations.
6.4.2 From OFF to ON with exciters in manual
When switching from OFF to ON with the exciters in manual mode, the apparatus
does not perform any check and the exciter that is currently set to on air is the
one that is aired.
If the mains signal is not OK, the exciters turn off automatically.
If the maximum drive power is exceeded during operations, the ATUNT5K0AQ &
ATUNT5K0AQ1D is set to fault status and power supply is cut to the exciters.A
message in the alarms menu signals this fault.
When the apparatus is set to EXT INT or AUX INT, the mute RF signals of the
exciters are not activated and may be modified by the operator.

6.4.3 Automatic changeover
When the ATUNT5K0AQ & ATUNT5K0AQ1D is in the exciter automatic
changeover mode, the power emitted by the on air exciter is checked constantly.
If at any time the on air exciter is no longer good (i.e. power drops to below the
preset level), the apparatus is kept operational whereas the exciter connected to
the internal Dummy Load turns on. If the latter one is good (i.e. it is capable of
supplying the required power), then the two exciters are changed over. Instead
if the alternative exciter is not good, no changeover takes place, the control unit
commands the mute RF of the exciter to Dummy Load, it waits 120 s. and repeats
the attempt. This procedure is repeated indefinitely until one of the two exciters is
considered to be good.
During the whole length of time during which there is no good exciter,
theATUNT5K0AQ & ATUNT5K0AQ1D keeps the WAIT LED on for signalling this
status.
Each exciter is fitted with its own mute RF. On being commanded, the piloting
signal must return to zero within 3 seconds at the most. If this does not occur, the
fault is recorded by an error message that is entered in the alarms menu.
If the mains signal is not OK, the exciters turn off automatically. If the piloting power
exceeds the limit during operations, the ATUNT5K0AQ & ATUNT5K0AQ1D is set
to the FAULT status and the power supply of the exciters is turned off. A message
in the alarms menu signals the fault. Keep in mind that the operator’s intervention
is required to exit from the FAULT status.
If the MAINS signal coming from the bus is not OK, the exciters are all turned off.
As soon as the MAINS signal is regular again, the evaluation cycle of the exciters
begins.
When the apparatus is set to EXT INT or AUX INT, the mute RF signals of the
exciters are activated and therefore both exciters are inhibited. When the external
interlocks are released, the system re-evaluates both exciters as during the phase
from OFF to ON.
6.4.4 Phase from ON to OFF
When the apparatus is set to OFF status and you press the ON button, the power
supply of the exciters is activated and the logic starts to evaluate the exciters.
During the evaluation phase, the WAIT LED stays ON.
When the apparatus is turned OFF, it memorizes the exciter on air. Consequently
when the machine restarts it can attempt to restore the previous conditions. On
the machine restarting, if the exciter that is to be aired does not attain the preset
power level whereas the spare one is operational, the apparatus performs the
changeover when the evaluation time (120 s.) expires.
On the machine restarting, if both exciters do not attain the preset power level,
the apparatus airs the one that had been present when the machine was turned

off, after the evaluation time has expired.
6.5 Protections and alarms
The ATUNT5K0AQ & ATUNT5K0AQ1D contains a complete protection and alarms
system, both at the individual modules level and at the control unit level.
The modules are fitted with a micro-processor-based system that manages any
malfunctions locally. The associated information is communicated to the control
unit for displaying and storing the events and for the centralized management of
the events that require it.
Certain LEDs of the ATUNT5K0AQ & ATUNT5K0AQ1D panel are dedicated to
the management of the alarms:
LED
WARNING
FAULT
WAIT
Description
This LED indicates a warning (something is
not correctly working, but the amplifier is still
working)
This LED indicates a fault (the transmitter
is shut off, the operator’s intervention is
required)
This LED indicates the wait status (the
transmitter is temporarily off, it will be
restarted as soon as the reason that keeps
it from working will be removed, or after
a fixed amount of time depending on the
reason of the intervention of the protection
system)
The ALARM RESET button is used for resetting the alarms and restarting the
machine.
