Running states
Description of the possible running states:
Transitions between running states
The transitions between states are done automatically and the system
adapts itself to the relevant operating mode depending on the line voltage
and on the DC BUS voltage. These transitions are:
F. H2/51
RPS power supplies. Running state diagram.
Status Meaning
0
Without power line connection. Stand by.
1
Loading the DC BUS. Temporary state.
2
Running in RPS mode (booster) or in RB6 mode (rectifier).
3
Running in REGENERATOR mode. The system works as a
generator discharging the excess energy of the DC BUS into
mains.
4
Emergency state.
Transition Meaning
A
The power line connection is made.
B
The time set as the minimum time limit (3.2 s) to charge the
DC BUS has been exceeded. The charge process has failed
and error
E315
of the DC BUS comes up. Temporary state.
C
The charge process has finished correctly.
The switch configuration defines either the
RPS running
mode (booster) or the RB6 mode (rectifier).
D
The bus voltage is higher than the nominal voltage set for
the DC BUS and the value of the line voltage is within the
limits set to work in generator mode.
E
The bus voltage is lower than the nominal voltage set for the
DC BUS and the switch configuration defines the RPS
running mode (booster) or the RB6 running mode (rectifier).
F The emergency stop has ended.
STATE 4
EMERGENCY STOP
STATE 3
GENERATOR MODE
STATE 2
RPS MODE (BOOST) or
RB6 MODE (RECTIFIER)
STATE 1
