SYSTEM START UP
When the power switch is turned on, some seconds are necessary before the system starts because the power
supply has a long start-up time in order to prevent overloading.
The display will then show the start-up procedure of the Amplifier and this will be ready for
transmission. With the ON AIR led blinking, slowly increase the exciter output power until you reach
the required transmission power and in any case not greater than 3000 Watts. When the display shows an
output of 150 watts, the ON AIR led stops blinking.
If the output power exceeds 3000 watts, the PWR led will blink and automatically the Mosfet bias voltage is
reduced in order to maintain the output power in the safety parameters. It is therefore useless to increase the
driving to have more power output.
By keeping on increasing the driving, you can damage the RF power Mosfet which is no covered by warranty, a
part from the warranty of the manufacturer.
Do not remove the AC power without first having performed the stop procedure , because if the Amplifier is still
connected to input power when is removed, this could damage the Equipment.
The installation of the Amplifier is now completed and the correct operation is indicated on the display showing
the following values:
•
ARCHIMEDE 3000
• OUT POWER up to 3000 Watt
•
REF POWER NORM.
And in the fourth line of the display will be displayed alternately:

The temperature of the pallet (MAX 85°C) and of the input air ( MAX 45°C)

Date and time
It is mandatory to provide adequate ventilation to the Equipment to maintain its internal temperature as low as
possible, in a recommended range of 5÷35° C. Even if the Equipment may work until 40°C his life expectancy
will be impaired by excessive temperature.
Vents in the walls and any other opening shall be fitted with a metal grating to keep away rodents and other
animals. Proper air filtering avoid dust and insects to be conveyed in the internal equipment causing over
temperature alarm. Make absolutely certain that the floor cannot be flooded during heavy rainfall. Even
moisture and/or dust may cause condensation build-up in the Amplifier. This can trigger destructive electric
arcs during the switch on/off system and thus cause damage that is not covered by the warranty.
