cialist who has been certified by the Chamber of Commer-
ce and Industry (master workshop). The device must only
be repaired by an authorized specialist who has been cer-
tified by the Chamber of Commerce and Industry (master
workshop), or alternatively by sending it back to ASTRO
together with a detailed description of the fault.
The power cord(s) must only be replaced by equivalent
genuine ASTRO replacement power cord(s).
Fuses must only be replaced with replacement fuses of
the same type and with the same ratings and melting
characteristics.
Important:
Compliance must be ensured with:
DIN VDE 0701 – parts 1 and 200, servicing
EN 50 083 – part 1, safety requirements
2.3 Equipotential bonding / grounding
The device must be properly grounded and installed in accor-
dance with EN 50 083 – part 1.
The requirements laid out in EN 50083 – part 1 and the national
legislation relating to IT/TT power supply networks must be com-
plied with
Operation of the device without a protective ground
connection, proper grounding of the device or equipo-
tential bonding is not permitted.

their operation.
Other special types available on request.
4. Programming the SAT distribution field
with the KC 3
4.1 Fundamentals
After plugging in the KC 3 programming device the Start
menu will initially appear. The software version number
is displayed..
Please quote this number whenever contacting our
customer service department.
The Start menu can only be accessed again later on by
unplugging and replugging the KC 3.
After plugging in the KC 3, you can press the “Menu
Read” button first to view additional data for the device
(no. of LNC inputs, redundant power supply unit
yes/no). Here, you can use the ↑and ↓cursor keys to
go to row four and access the menu for
Setting up a device password:
Use the ←or →cursor keys to activate the password
function. After pressing the “OK Store” button you will be
asked to enter the new password. If the password func-
tion is active then it will not be possible to save changes
without the password. Please contact the manufacturer
if you cannot remember your password.
3 Type designations 4 Programming with the KC 3
5
After plugging in the KC 3, you can use the ←or →cur-
sor keys to access the menu for adjusting the parame-
ters of the SAT distribution field.
4.2 Setting the bus address
After plugging in the KC 3, press the ←or →cursor
keys to access the menu for setting the bus address.
Then press the ↑or ↓cursor keys to go to the third row
of the menu, where you can use the ←or →cursor
keys to select a bus address value between 31 and 50.
Then press “OK Store” to save the selected settings.
The message “Data saved” will appear for about 1
second.
4.3 Programming the SAT inputs
After plugging in the KC 3 and pressing the ←or →cur-
sor key twice you will go to the menu for setting the bus
address and on to the menu for programming the X
input of the SATdistribution field. You can then use the
↑or ↓cursor keys to go to the second row of the “X
input” menu for
Adjusting the attenuation
with the ←or →cursor keys in increments of 0.5 dB. The
attenuation can be set to a range from 0 to 16 dB. Press
the button “OK Store” to save the changes made. The
message “Data saved” will appear for about 1 second. If
you press the button “Menu read” in the second row as
well then this will take you to the menu for
Activating the 7 dB slope equalization:
The equalization can be activated or deactivated by
pressing the ←or →cursor keys. Here again you need
to press “OK Store” to save the changed settings.
4.4 Monitoring of the remote powering / alarms
The remote powering which can be activated on the front
panel of the device and can also be monitored:
Use the
↑or ↓
cursor keys to go to the third row of the “X
input” menu, where you can change all settings for monito-
ring the remote powering and for the alarms which are trig-
gered when certain values drop below their alarm thres-
holds. The current remote feed current is displayed here
initially. Pressing the “Menu Read” button will take you to
the activation and deactivation of the alarms, which is set
with the aid of the
←or →
cursor keys. Press the “Menu
Read button again and use the
←or →
cursor keys to
adjust the lower alarm threshold in 50 mA increments (from
50 mA to 250 mA). The upper alarm threshold is adjusted
in similar fashion after pressing the “Menu Read” button
(range from 100 mA to 350 mA).
The fourth row of the “X input" menu shows the current
temperature of the device.
All of the information for the “X input” menu applies analo-
gously to the “Y input" menu.

5. Programming the SAT distribution field
with the HE programming software
5.1 Inserting the SAT distribution field into a project
One or more SAT distribution fields can be inserted under
“Planning →Project Data” in the HE programming soft-
ware.
After entering the SAT distribution field it can be called
up in the HE programming software under “SAT-ZF pre-
distribution”.

5.2 Programming the SAT inputs
Any of the satellites stored in the database can be
assigned to the SAT inputs.
The next step is to select the polarization and the band.
The attenuation of the SAT distribution field can also be
adjusted via the HE programming software. The adjust-
ment range is 0 to 16 dB, with increments of 0.5 dB.
In addition, the 7 dB slope equalization and the monito-
ring of the LNC remote feed can also be activated or
deactivated via the software. Values between 100 mA
and 700 mA are available for the lower threshold, with
values between 200 mA and 800 mA available for the
upper threshold (in increments of 50 mA).
5 Programming with the HE programming software 5 Programming with the HE programming software

The current remote feed current is displayed after the
SAT distribution field has been read out. Read it out
again to update the display.
All operating information for the X-input applies analo-
gously to the Y-input.
6. Indicator lamps
The green LED on the front panel of the device indica-
tes that the power supply unit is operating without any
faults. A green LED is also used to indicate if the LNC
remote feed is activated.
If the monitoring of the LNC remote feed is activated
and the current reading moves outside the previously
specified window then this is signaled with a red LED.
