4.1 Operating
Statuses
The following operating statuses are possible:
"PowerUp":
Status after PowerUp or Reset. The control system checks the
ambient conditions.
ambient conditions.
"on":
Mains operation: The SBS supplies the load.
"ready":
In the event of load voltage deviation or INV failure / switch-off, the
SBS takes over the load without interruption, i.e. the SBS control
system switches over to the "on" operating status.
SBS takes over the load without interruption, i.e. the SBS control
system switches over to the "on" operating status.
"blocked":
The SBS control unit is blocked. In the event of load voltage deviation
or INV failure / switch-off, the SBS does not take over the load, i.e.
the SBS control system remains in the "blocked" operating status.
The operating status "blocked" is activated in the event of mains
failures or phase deviations.

The operating status "blocked" is activated in the event of mains
failures or phase deviations.
"Fault":
A fault has occurred in the SBS. This fault must be remedied and
acknowledged using the Reset button.
acknowledged using the Reset button.
ATTENTION:
If the INV is switched off in the event of a blocked or faulty SBS, the
loads are no longer supplied with power.
If the INV is switched off in the event of a blocked or faulty SBS, the
loads are no longer supplied with power.
4.2 Switchback
Attempts
Should the load voltage deviate excessively e.g. due to overload of
the INVs or load short circuits (see chapter 4.4), the loads are
automatically switched over to the SBS without interruption. Then the
loads are also automatically switched back to the INV. It this
switchback attempt fails, the SBS continues to supply the loads. After
3 unsuccessful switchback attempts within 1 minute, the INV is
switched off and the loads remain supplied by the SBS.
