Fronius SYMO Series User Manual

-
Overcurrent (current flow > 3 A, e.g. due to a short circuit in Fronius Solar
Net ring)
-
Undervoltage (no short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if too
many DATCOM components are in Fronius Solar Net and the electrical sup-
ply is insufficient)
In this case, an additional power supply is required for the Fronius DATCOM
components using an external power supply (43,0001,1194) on one of the
Fronius DATCOM components.
Check other DATCOM components to detect any undervoltage present.
After a shutdown due to overcurrent or undervoltage, the inverter tries to restore
the energy supply in the Fronius Solar Net every 5 seconds so long as there is an
error.
Once the error has been corrected, power is restored to Fronius Solar Net within
5 seconds.
Example Logging and archiving inverter and sensor data using a Fronius Datamanager and
Fronius Sensor Box:
Data network with three inverters and one Fronius Sensor Box:
- inverter 1 with Fronius Datamanager
- inverter 2 and 3 without Fronius Datamanager.
= termination plug
External communication (Fronius Solar Net) takes place in the inverter via the
data communication area. The data communication area has two RS-422 inter-
faces: an input and an output. RJ45 plug connectors are used to establish the
connection.
IMPORTANT! Only one Fronius Datamanager in primary operation is permitted
per Fronius Solar Net Ring. Switch other Fronius Datamanagers to secondary op-
eration or remove them (see chapter "Controls, connections, and indicators on
the Fronius Datamanager 2.0").
Unused option card slots can be closed by replacing the cover (item number -
42,0405,2094), or an inverter without Fronius Datamanager (light version) can be
used.
