If not otherwise specified, the following descriptions are valid for all Archimede High Power models.
8.1
Turning on/turning off
8.1.a
First switching on (during installation)
The amplifier stores in its memory the operation mode in which it was working before the power supply was turned off
or a power line interruption (blackout) took place. Therefore, depending on whether it had been previously turned on
or not, the switch-on operations may vary as follows.
The amplifier output power must be adjusted only and exclusively through the menu of the amplifier itself, and NOT
through the driving power. For this reason, follow the instructions given below.
1)
Make sure that all installation conditions as described in Chapter 7 are met, and that all connections described in 7.4.a, 7.4.b,
7.4.c and 7.4.d have been properly made. You can connect a proper dummy load to the amplifier
’s R.F. output instead of the
antenna.
2)
Make sure that the exciter output power is zero.
3)
Turn on the
Power ON/OFF
switch [18] on the rear side.
4)
At this stage, two conditions may take place:
The amplifier turns on,
so do the fans and the display (see note below). This usually
– and automatically - happens
after an AC power line black out. If so, you can skip directly to point 6)
The amplifier
DOESN’T turn on,
the display will briefly show some screenshots before entering in
Stand-by
mode -
In such case go to the next step.
5)
Keep the
ON/STAND-BY
button [6] pressed for a couple of seconds: the amplifier and the fans will turn on. The display
briefly shows some screenshots. At the end the green
ON
LED [9] will steadily glow and the working page (the one normally
shown in the normal operation
10.2) will steadily stay on the display:

6)
Switch on the exciter.
7)
Gradually increase the driving power until it reaches the rated Input level. Under these conditions, the amplifier will not yet
deliver its output power.
Warning: DO NOT exceed the rated Input level of the driving power (
7.4.d), otherwise the equipment could be
damaged.
As soon as the equipment is powered, the fans will start turning at the minimum speed. Then, the control board will change
their speed according to the heatsink temperature.
8.1.b
Adjusting the output power
8)
Should you wish to adjust the output power, from the over stated working page press the knob (as it was a normal
pushbutton) in order to access the main menu, then turn the knob counterclockwise in order to move the cursor

to the left of
