The busbar voltage and current values are displayed with three decimals before and one decimal after the decimal point. The display accuracy corresponds to class 1 with respect to the rated output value of the unit.
Remote signalling is carried out by means of
Assignment of the signal terminals:
SBS fault:
In the event of a signal, X4.2 – X4.3 close, no fault: X4.2 – X4.1
•When the SBS is disconnected from the power supply (no mains / INV supply), a fault is signalled!
INV operation:
In the event of a signal, X4.4 – X4.5 close
The remote signals are designed for safe isolation. The minimum load should not be below 12 V and 0.1 A.
4.13Operating modes
Two operating modes can be selected using the DIL switches (see chapter 4.11).
Switchover without gap:
The switchover from INV to SBS is always carried out without interruption. If the INV and SBS circuit are not synchronous, the SBS blocks. If the INV is switched off due to asynchronism or if it fails, the load is not supplied by the SBS.
This operating mode is set ex works and is recommended.
NOTE:
i If the mains are poor or the SBS circuit is supplied by a diesel generator for example, the SBS can be temporarily blocked due to frequency deviations.
