Technical description SI4548_6048-US-TB_en-13 141
Error Error Sunny Island has a fault; in case of fault, contact is
open (relay is deactivated).
If the autostart is activated, the error status will be
left within 15 s and restart triggered. If the start is
unsuccessful this procedure will be repeated until
the autostart counter has expired.
Warn Warning The Sunny Island has warning pending. If the
warning disappears, the "Warning" state is exited.
When a warning disappears depends on the type
of warning.
Run Run Sunny Island is in operation, contact is closed
(relay is activated) if the device is running in
inverter operation.
BatFan Battery Fan Relay is used for automatic battery room ventilation
(switching the fan).
The "BatFan" function is responsible for the
ventilation of the battery room and provides
ventilation of the room in the event of battery
gassing.
AcdCir Acid Circulation Relay is used for automatic acid circulation
(switching the electrolyte pump)
The acid circulation enables mixing of the acid and
thus reduces acid stratification in the battery.
MccBatFan Multicluster battery fan Relay is used for automatic battery room ventilation
(switching the fan).
"MccBatFan" is the request from the master of the
main cluster that is transmitted to a master of an
extension cluster in order to use its relay for the
battery room ventilation.
MccAutoLod Multicluster auto
Loadshedding
Automatic disconnection of the loads via an
extension cluster in the Multicluster system
"MccAutoLod" is the request from the master of the
main cluster that is transmitted to a master of an
extension cluster in order to use its relay for the
automatic disconnection of the loads.
