1.4. Installation:
First time start-up procedure:
1. Verify the power line supply and the voltage regulator output. For 220V or 380V you have to
use a three phase voltage Y or Delta connection, respectively;
2. Connect the transmitter RF output (on the top of the transmitter) to a 50 ohm antenna or
dummy load. Pay attention to the maximum curvature of the coaxial cables that are being
used;
3. If the equipment has an audio and video modulator, connect the video signal to the video input
jack 75 ohms and the audio signal to the audio input jack 600 ohms balanced located at the
top of the transmitter;
4. If the equipment is a retransmitter, connect the Booster converter output to the IF input jack;
5. Connect the ac input at the rear of the equipment. It is recommended using a power cable feed
10.0mm;
6. Reduce the IF level from the audio and video modulator by turning its control counter-
clockwise. For retransmitters, The IF level control is located at the front panel of the Channel
converter. For Dual Driver Equipments, repeat the process for both Driver A and B;
7. For Dual Driver equipment, place the AUTO/MANUAL selector switch to the MANUAL position,
and the PREF. A/PREF. B selector switch to the PREF. A position;
8. Disconnect all 650W amplifiers # modules;
9. Turn on the equipment by pressing the main switch at the front panel of the channel converter
and at the right superior panel of the equipment. For Dual Driver turn on the main switch of
channel converter “B” also;
10. Ensure that all the voltage supplies (at the Amplifier # modules connector) from each 650W
amplifier module are ok;
11. By this time, only the “A” Driver will be running;
12. Check all the voltage supplies and the local oscillator of the channel converter against the
equipment test list;
13. Check the Blower system. If it is rotating incorrectly check again the incoming phase voltage;
14. Turn off the equipment and reconnect all amplifier # modules. Ensure that the IF level is at its
minimum level;
15. Turn on the equipment and check again all the voltage supplies;
16. Ensure that the SIGNAL, SUPPLIER “A” TEMPERATURE, SUPPLIER “B” TEMPERATURE, LOAD
TEMPERATURE, FILTER REFLECTED POWER, ANTENNA REFLECTED POWER, PHASE LOSS
alarm LED’s are off, otherwise contact our representative;
17. Place the selector switch of the superior panel to the Video Signal position. Increase it slowly by
turning the IF level control clockwise. Observe the Reflect power alarm LED at the front panel.
If it lights on, turn off the equipment and check the antenna connections one more time;
18.
It is recommended to increase the IF level for a reading of 50% on forward power level at first.
Follow the 19, 20, and 21 steps and let it running for a while. If everything is ok increase the IF
level for a reading of 100% on forward power level and repeat the following steps;
19. By increasing the IF level, the Forward Power LED’s of each amplifier # module will turn from
red to green;
