Troubleshooting/Problem Solving

19.4 Master Slave Handling

Each device detects the faults separately and saves it. The slaves transfer their errors to
the master. The master collects these error messages and enters the slave errors as
warnings into its history.
Slave 1 has detected an overtemperature fault (F138). It enters this error in its
history and reports it to the master that also enters it as a warning into its failure
history ("Menu #320 Failure History").
The following message appears in the lower line on the
master:
If error 138 is still active on slave 1, the Enter symbol appears at the end. After
confirming the fault on the master using <ENTER>, the fault is forwarded to the
corresponding slave.
Display on the master after confirmation:
The error and event memory are not compared between the master and slaves.
19.5 Handling Pending Errors During the Booting
Procedure
During the booting procedure, all pending errors are generally confirmed without an
entry being made in the history. This way, an error that is still pending after the booting
procedure is re-entered or if the system detects that this error has stopped, it is entered
as no longer being present.

19.6 Display of Errors and Events

Each error and each event have a unique three-digit display number that is created
according to the parameter/measuring value assignment. The events and errors have
the identical numerical range:
• 1xx - INV - Inverter
• 2xx - BAT - Battery
• 3xx - EXT - Extern
• 4xx - GEN - Generator
• 5xx - GRD - Grid
