TESTS ON THE OFFLINE MODES
After the configuration of the regulator is done, it must be made the first power-up applying the excitation to the
synchronous machine with no load and disconnected from the line or other machines. The main objective is
detecting wrong connections and bad configurations.
10.5.1
Turning On and Off the Regulator with Machine Spinning
1. With the regulator OFF, check if the "Automatic" and "Manual" commands are toggling the operating mode of
the regulator via HMI, via supervisory software or via specific keys on the digital inputs.
Result: _____________________________________________________________________________
2. With the machine spinning, check the remanent voltage measurement, the terminal current and the frequency
on the HMI, or supervisory software.
Result: _____________________________________________________________________________
3. Put the regulator in the manual mode (MECC) and set the excitation current reference to 20% of the rated
excitation current value. Enable the regulator and wait for the ramp to reach the reference setting.
