Danger:
avoid the
risk of damaging the machine
by grounding it correctly. As
such, connect the ground conductor of the power supply cable to the specific
terminal in the multipole socket and check the efficiency of your own grounding
system.
Check that the multi-turn RF PWR ADJ trimmer on the RF module is turned
clockwise completely (as factory setting). As such, the action of the Automatic
Gain Control (AGC) is disabled.
5.2 Operation
After having plugged in the power supply socket at the back of the machine, power
on the amplifier via the switchboard. The ON LEDs on both modules will turn on
and the forced cooling fans will start running. The LCD shows the first introductory
screenful and then switches to a screenful that indicates the forward and reflected
power values.
Turn on the exciter (at lowest power) and wait until it locks to the work frequency.
Once locked, increase power gradually and check the amplifier’s display. Increase
the exciter’s power until the amplifier’s output attains the desired value, max.
