I) led indicators as memory of the protection interventions happened (yellow color);
J) led indicator to indicate the voluntary protections service stand-by for short time for a
final amplifier overload.
K) led indicator to indicate the voluntary plate power supply stand-by.
The commands relative the final power stage amplifier are the followings
A) key selector to enable the tunings push buttons;
B) two push-buttons at three positions that allow the setting of the input tuning of the tetrode
amplifier cavity;
C) a push-button at three positions that allows the setting of the frequency tuning of the
tetrode amplifier cavity;
D) a push-button at three positions that allows the setting of the working impedance of the
tetrode anode;
E) a selector at two positions that allows to put in stand-by the tetrode anode power supply;
F) a selector at six positions to select the different measures of the multimeter;
G) a selector at two positions that allows to select the control grid or screen grid current
measures;
H) a selector at two positions that allows to select the forward and reflected power
measures;
I) a key selectro that allows to put in stand-by for a short time the overload protections of
some amplifier’s parameters;
J) a push-button that allows to reset the counting and the memories of the protections
interventions occurred;
K) a push-button that allows to change on the diplay the indication from protection
interventions counter to status of the warm-up timer;
L) a main switch with overload protection that allows to stop the mains voltage to all service
circuits of the amplifier.
Please refer to Table A for the electrical specifications and Table B for the mechanical
specifications.
1.4) PANNEL ALARMS
The panel alarms (fig.2) has numbers indicators of different colors: the red leds point out a
condition of current alarm, the yellow leds show that there has been a condition of alarm
then reentered.
This encircled is characterized by the following protections: excess of VSWR, excess grid
current, excess of anodic current, insufficient power tension, excess of temperature, opening
panel, insufficient ventilation and a key interrupter.
On the panel there are two interrupters, one visualizing the preheating time of valve
filament the second reading the number of reset cycles that the circuit protection has
performed.
Finally a digital display with four digits show the time or the n° of cycles (the two digits of
left), the air temperature of expulsion (°C) (the two digits of right).
Prese, refer to the TABLE A for electrical charcterostocs and the TABLE B for
enviromental specifications.
