can be updated following the appropriate
procedure. All the LED's on the front
panel are on.
Reading of the configuration parameters
stored in the EEPROM.
All the LED's on the front panel are off.
The rectifier is supplied and the DC
voltage reaches the nominal value. All
the LED's on the front panel are on.
The microprocessor checks that all the
start-up conditions are good for restart.
Led #1 lit green. Led #8 lit orange.
The IGBT rectifier bridge starts to
modulate; VDC voltage reaches the
nominal value. LED #3 is lit green: DC
voltage present.
The microprocessor checks that all the
bypass parameters
rotation, frequency) are within tolerance.
Led #2 lit green. The static bypass
switch is closed. LED #6 lit orange.
Closing of the battery circuit breaker.
Led #4 lit green.
The load is fed by the static bypass
switch. Circuit breaker MBCB is still
closed. Led #7 lit green.
The load is fed by the static bypass
switch and the inverter can be started.
LED #8 off.
The modulation of the inverter bridge is
