4. Converter operation
4.1
Starting the output of power
After the preliminary operations, connecting the equipment to the mains and to an
eventual load, are done it’s possible to turn on the converter acting on the main
switch.
Note: the main switch will not activate if the emergency circuit is open or
the emergency push-button is pressed.
Once the equipment is turned on it’s possible to start the output of power in the
following ways:
•
Pressing the on-off push-button on the front panel
•
With command from serial port; entering the appropriate string.
•
Activating the appropriate digital input.
Under these conditions the converter will take immediately the voltage and
frequency set.
4.2
Setting voltage and frequency
The setting of voltage and frequency output can be done:
•
by means of the potentiometers on the front panel
•
by means of analog signal 0 ÷ 10V
•
from serial port
4.3
Scale selection
The FVC converters can have one or two output scales in order to supply the
maximum power with different full-scales.
The scale selection must be done with the appropriate selector in stand-by mode.
An eventual change of scale, while the output is on, will take place only after
the converter is switched “off”
4.3
Display of set values
In stand-by it’s possible to visualize on the displays the voltage and frequency values
simply pressing the “F1” push-button
“F1” pressed = visualization of voltage and frequency entered
“F1” released = off
