Command type selection
The selection of the command type:
•
front panel
•
analog or digital inputs
•
serial port
can be done via serial communication by means of “FVC Manager” software (look at
paragraph 12).
4.5
Measurements display
While the output is on the converter shows on the displays the concatenated output
voltage between the phases L1-L2 and the current on phase L1.
Pressing “F1” it’s possible to visualize in sequence:
•
FREQ = output frequency
•
F1 V = voltage L1-L2
•
F1 A = current L1
•
F2 V = voltage L2-L3
•
F2 A = current L2
•
F3 V = voltage L3-L1
•
F3 A = current L3
If no keys are pressed within 3 seconds the displays will show the initial condition
4.5
change of scale
The FVC converters can have two voltage scales, this allows to supply the maximum of
energy even with lower output voltages.
The change of scale is done with appropriate selector on the front panel and has effect
only with the equipment in stand-by.

Maintenance instructions
•
Check periodically the air vents, clean them or change the filter (if present);
•
Check and tighten periodically the bolts of the connections between the power
outputs and the external circuit under test (in case of high currents).
