4 Function of the SBS (optional)

For the technical data or unit settings, refer to the chapter “Technical

Data”.

4.1Operating Statuses

The following operating statuses are possible:

"PowerUp":

Status after PowerUp or Reset. The control system checks the 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.

"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.

"Fault":

A fault has occurred in the SBS. This fault must be remedied and 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.

4.2Switchback 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.
