196 SI5048U-TUS121440 Technical Description
The master shows the following message after
confirmation.
20.4 Handling Pending Failures During the Booting Procedure
During the booting procedure, all pending failures are generally confirmed without an entry being
made in the history. This way, after the booting procedure failure that is still pending will be re-entered,
or if the system detects that this failure has stopped, it is entered as no longer being present.
20.5 Display of Failures and Events
Each failure and each event have a unique three-digit display number that is created according to the
parameter/measuring value assignment. The events and failures have the identical numerical range:
• 1xx - INV - Inverter
• 2xx - BAT - Battery
• 3xx - EXT - Extern
• 4xx - GEN - Generator
• 5xx - GRD - Grid
• 6xx - RLY - Relay
• 7xx - SYS - System
• 8xx - AUX - external devices and components
No Comparison between Master and Slave
The failure and event memory are not compared between the master and slaves. When the
Sunny Island system starts anew the failures in the slave devices are confirmed.
Meaning of the abbreviations
”F” marks a failure, ”W” marks a warning and ”E” marks an event.
In the event of a failure, and provided it is recorded, ”!” is displayed for a failure that has
occurred and ”C” is displayed for a failure that has stopped.
