"UniVert 2" inverter
4.3AC Mains Input (X1)
The SBS is connected to a 230 V AC mains.
The input voltage is fuse protected outside the SBS. For details refer to the technical data.
The input voltage is continuously monitored (see chapter 4.4).
When the mains voltage is present, the green "mains present" LED lights up.
4.4AC Busbar (X2)
The AC busbar is either supplied by the INV output voltage or the SBS output voltage which corresponds to the SBS circuit voltage.
The INV output voltage is regulated to 230 V 50 H (see chapter 3.9) and monitored (see chapter 3.5).
The load is only switched over to the SBS circuit if it lies within the defined tolerances and if a load voltage deviation is detected.
4.5AC Mains Monitoring System
When the mains voltage is no longer within the tolerance range, the "mains present" LED goes off.
The SBS changes the operating status from "ready" to "blocked". If the SBS is fired, the operating status does not change!
The acknowledgement is carried out automatically as soon as the mains voltage is back within the tolerance range. The green "mains present" LED is lit, the SBS changes from "blocked" to "ready".
4.6AC Busbar Monitoring System
If the load voltage leaves the tolerance range, the load is switched over to the SBS circuit without interruption. For this switchover, the SBS must be in the "ready" operating status.
4.7Temperature Monitoring System
Overtemperature is signalled by the red "collective fault" LED if the heat sink temperature exceeds critical values. Acknowledgement is made when it has cooled down.
Overtemperature can result from e.g. high ambient temperature, constant overload of the SBS or from fan failure.
4.8Monitoring of Functions
After connecting the input voltage, the
4.9Reset Button
The Reset button is used to acknowledge SBS faults. The Reset button must also be pressed to accept the settings of the
DIL switches.
