20.4 Handling of Pending Errors 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, a failure that is still pending will be
reentered, or if the system detects that this failure has disappeared, 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 ‒ External
• 4xx ‒ GEN ‒ Generator
• 5xx ‒ GRD ‒ Grid
• 6xx ‒ RLY ‒ Relay
• 7xx ‒ SYS ‒ System
• 8xx ‒ AUX ‒ External devices and components
