6.1 Exciter (DTVCE)
Note: not change the frequency until you have properly calibrated the output
lter.
•Set the exciters following the instructions of the exciters that you are used to
set the desired operating frequency. Adjust the output power of exciter to the
power required to drive your transmitter.
Before that you enable the delivered power from exciter, it is suggested to
check and, in case, correct the basic parameters under own necessity:
• frequency
• power
Note: Some information here contained may be not necessary for the proper
functioning of your transmitter.
•To enable/disable the power supply, please read the instructions in the manual
ofyourexciter.Itcanbedonetipicallyintherstsecondsofswitchingonof
exciter. In this way, you can change the working parameters before you begin
to transmit.
Note: turn the encoder to move the cursor shown on the display; if you turn the
encoder to the left (counterclockwise), the cursor moves rightwards, if you turn it right
the cursor moves leftwards; it also permits to increase or diminish the parameters
(turning the encoder left diminishes the parameter, turning it right increases it) or to
select an item from a list of options. The rotation of encoder causes the lighting of the
display, in case it is not been lighted.
Push the button once when the cursor is on the name of a menu to enter in that menu,
pushitwhenthecorsorisonthenameofaparametertoenterinmodicationmode(the
cursorstartsblinking);afterthemodicationofaparameter,pushthebuttontosavethe
new value. The pushing of encoder causes the lighting of the display, in case it is not
been lighted.
After having modified the value of a parameter, the cursor goes on
blinking for approximately 10 seconds, waiting for confirmation from the
user. If the user doesn’t confirm the new value (i.e., the button is not
pressed), the cursor stops blinking and remains on the selected parameter.
If no controls are operated during 2 minutes, the exciter returns to the default menu,
and after 5 minutes of inactivity the display lighting will be turning off.

6.2.3 Analogue instruments
The control unit of DTUTT1K2HP1D contains an analog meter with a rotating
selector that are useful for an immediate display of the following parameters:
Function Description
FWD PWR Transmitter direct power
RFLPWR Transmitterreectedpower
UNBAL Transmitter unbalancing power
PWR EXC1 Power supplied by the exciter currently
connectedtotheamplier.Thisvalueis
measured by the machine in the splitter
section
PWR EXC2 Power supplied by the exciter currently
connected to the internal load. This value
ismeasuredbytheamplierinthesplitter
section
EXT FWD PWR Direct power of an external combiner.
EXTRFLFWD Reectedpowerofanexternalcombiner.
EXT UNBAL Unbalancing power of an external combiner.
These three values are used when the
transmitter is connected to a 1+1 system.
The SET outputs may also be connected to
these quantities.

Refer to chapter 5.4 that provides the instructions for turning on the DTUTT1K2HP1D
in the various cases.
6.3.1 Preliminary operation
Before activating this piece of equipment, the necessary connections must be
performed, and in particular:
• Power supply
• Modulating signals (TV, Audio or MPX, RDS...)
• RF load (antenna feeder or dummy load)
About to the connections of the power supply and the modulating signals, please
refer to chapter 5.1.
Themachine’sRFoutputisthe“EIA15/8”angedtypeandisaccessedonthe
roof of the DTUTT1K2HP1D . If a dummy load capable of dissipating the RF
powergeneratedbythetransmitterisavailable,itisadvisabletorunthersttests
by connecting to it rather than to the transmission antenna.

6.3.2 Power-on
Whenpowering-onthetransmitterthersttime,performtheoperationsoutlined
in the table below.
The “Result” column indicates the immediate results of the operations performed
plusafewindicationsthatconrmthatthemachineisworkingefciently.
Should any inconsistencies occur as compared to these indications, interrupt
the procedure and identify the reason for the malfunction before resuming the
procedure.
Operation Result
Close the “Transformer Breaker” isolating switches
The power supply unit carriages are
powered
Turn the “Mains” switch The whole transmitter is powered. The
machine is activated in the same status it
was in when it was turned off the last time
Press the OFF key of the control unit RF emission by the transmitter is inhibited;
theexcitersareoff;theRFampliermodules
are off
Press the EXCITER CHANGEOVER key of the control unit
The automatic management for the exciters
changeover is disabled. The MANUAL LED
must be on (otherwise press the key again)
Set the parameters of the control unit 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
Set the exciters 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.
Press ON 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.
