8 Product Maintenance

6 of 8

3 of 8

Always disconnect the product from the power grid and wiring before performing any
maintenance of the product. If you have to enter places with a risk of fall, pay attention to
your safety.

Use only dry cloth to clean the product and do not use any liquid agents.
Coaxial cables installed outdoors should be replaced once in a few years. Unscrew all F
connectors and clean connector contacts, resp. shorten the coaxial cable by approx. 2 cm, every 2
years.

Check the state of power supply and its mains cord periodically. If the mains cord or the
mains plug of product is damaged, it must be replaced by manufacturer or qualified
technician to prevent any dangerous situation. Let the product serviced if the housing of
power supply is damaged.

If not used for long time, disconnect the product from the power grid.

9 Troubleshooting

Always disconnect the product from the power grid before working on product, otherwise
you risk the electric hazard. Pay attention to your safety if you have to enter places with a
risk of fall.

In the case the product does not work and LED of power supply is on:

• Check if the terrestrial and satellite antennas are correctly fixed, optimally set and

connected to the product, satellite and terrestrial receivers turned on, plugged on and
correctly set.

• Check the connector connections. The inner conductor of coaxial cable must be in

contact with the inner conductor of F socket and the shielding of coaxial cable with F
connector. Replace broken or interrupted coaxial cable.

• Sometimes the reset of the multiswitch microprocessor is enough to fix the problem.

Pull out the power plug of the multiswitch and satellite receiver from power grid and
then re-plug them a few seconds later.

In the case the product does not work and LED of power supply is off or blinks:

• Check that the product is connected to the power grid with AC voltage. If not, connect

the product to the power grid with correct AC voltage.

• Disconnect the product from the power grid and check that there is no short-circuit on

the input satellite coaxial cables, which prevents the power supplying of LNBs. If yes,
remove short-circuit and re-plug the product into the power grid again.

• The power supply can fail temporarily in case of overload or overheating. The cause can

be current consumption of devices connected to the satellite inputs of product which
exceeds the specifications, see section 2 Product Specifications. The next cause can be
the overheating of product in consequence of wrong installation, see section 4 Product
Storing and Installation. Disconnect the product from the power grid, remove the cause,
and re-plug the product into the power grid after a few minutes again.

If the failure cannot be removed, please contact your distributor.

• in the reach of children

Do not expose the apparatus to dripping or splashing. Use the aparatus only in moderate climates
(not in tropical climate). Fix the product firmly on a wall or another hard and inflammable surface
with screws and dowels. The mains socket must be placed near the product. The mains plug

shall remain readily operable. The mains socket and plug must be easily available.

• The product shall be in no case held only by the connected cables.

• Ensure the free space for the air circulation (space on sides and bellow the product

should be at least 20 cm and the space over its top at least 50 cm).

• Do not cover the product (with curtains etc.).

• Do not place any containers with liquids (vases, glasses etc.) or naked flame sources

(lighted candle etc.) on the product or near the product.

5 Product Connection

Connect the product in accordance with this manual and valid regulation in your country. Use
high quality 75 Ω coaxial cable designed for satellite reception. Mount the F connectors (screw,
crimp or compress type) on the ends of coaxial cables, in the case of using the screw F connectors
proceed according to the following picture and instructions:

1. Remove the outer coaxial cable coating in the length of approx. 15 mm.

2. Roll up the metal shielding braid and the shielding foil underneath and cut the shielding
with scissors to approx. 5 mm.

3. Remove approx. 10 mm of the inner plastic insulation (approx. 5 mm of the insulation

remains in a place).

4. Carefully screw the F connector on the cable end until the plastic insulation levels with
the F connector opening.

5. Check there is no short between the inner conductor of coaxial cable and F connector.

The coaxial cables shall not be broken, the minimum bending radius should be 5 cm. Connect the
F connectors into the F sockets of product and fasten them with an appropriate force.

Connect input F sockets marked A-P with convertors (LNBs) outputs according to the

• Connect input F socket marked TERR IN with output of terrestrial antenna, eventually
with output of terrestrial antenna with terrestrial antenna preamplifier.

• Connect output F sockets marked 1 to actual number of outputs of multiswitch with
other components in distribution system (satellite receiver, terrestrial receiver, wall
socket etc.).

• Connect connector marked with protective bounding symbol with protective bounding
conductor, see section 10 Symbols Explanation.

• Connect the mains plug into the mains socket with voltage according to section 2
Technical Specifications.

In case when quad LNBs are used, it is necessary to switch on 22 kHz, see section 6 Product
Settings. If some of outputs are not used, it is appropriate to terminate them with 75 Ohm loads. If
not terminated, insertion loss curve in terrestrial band may be rippled.
The wiring examples are shown in the section 11 Wiring Diagrams or at the website www.emp­centauri.eu.

6 Product Settings

For all SAT inputs, it is possible to change level of signals by means of attenuators in 15 dB
range. The minimum attenuation is in clockwise stop position, the maximum attenuation is in
counterclockwise stop position (for terrestrial input switching to passive mode, see below). Set
attenuators very gently, do not turn them behind stop positions by force.
22 kHz signal can be switched on / off by DIP switch located at right low side of the multiswitch.

Lever 4 in position OFF/ON switches on/off 22 kHz to satellite inputs C and D.

•

Lever 3 in position OFF/ON switches on/off 22 kHz to satellite inputs G and H.

•

Lever 2 in position OFF/ON switches on/off 22 kHz to satellite inputs K and L.

•

Lever 1 in position OFF/ON switches on/off 22 kHz to satellite inputs O and P.

•

The lever is in ON position when closer to upper side of the multiswitch. The lever is in OFF
position when closer to lower side of the multiswitch. Lever 1 is the closest to the multiswitch
power supply.
Active and passive mode of terrestrial band can be selected by turnable switch, passive mode is
selected by turning the switch to counterclockwise stop position. The return path is available in
the passive mode.
If input F socket marked TERR IN is in short connection or maximal allowed current is exceeded
(see section 2 Technical Specifications), the voltage decreases down near to 0 V. Quality of
signals is not affected however.
Satellite receiver must be set up according to following table:

LNB DiSEqC command for

switching to given LNB

LNB 1 Position 0 + Option 0 DiSEqC 1 or DiSEqC A (according to satellite receiver)

LNB 2 Position 1 + Option 0 DiSEqC 2 or DiSEqC B (according to satellite receiver)

LNB 3 Position 0 + Option 1 DiSEqC 3 or DiSEqC C (according to satellite receiver)

LNB 4 Position 1 + Option 1 DiSEqC 4 or DiSEqC D (according to satellite receiver)

7 Safety

Due to security reasons the product and wiring in which the product is connected, must be
grounded properly. Use the terminal identified with the appropriate symbol to ground the
product. Make sure the antennas are grounded properly.
Connect all devices to power grid only after all connections are finished and checked.
The product works with the AC voltage, see section 2 Technical Specifications. Make sure,
that the local AC voltage corresponds to the operating voltage of product.
No objects can be placed on the mains cord for prevent its damage or break. No hot objects
should touch the mains cord.
While disconnecting the product from power grid, never pull the mains cord but the mains
plug to prevent the mains cord damage. Pay attention that the mains plug holds tight in the
mains socket. Loose mains plug or mains socket means the danger of fire.
Never disassemble the product connected to the power grid, you risk the danger of electrical
shock.
Never work on the wiring (including satellite and terrestrial receivers, TVs) during or
before a storm. A lightning stroke into the antenna may cause dangerous overvoltage in the
product metallic parts.
The product should be disconnected from the wiring immediately if it gets into contact with
liquids (dropping water, spilled drinks etc.).
