12.2 Analyzing Failures
When a warning is given or a failure shown by the LEDs and the
411 Current Overview
menu, additional information can be dis-
played.
This is generally divided into two categories:
●
External events (incl. insulation and grounding failures)
●
Internal events
The additional information on the failures are logged in two sepa-
rate menus:
●
External events: Menu
480 Ext. Events
●
Internal events: Menu
620 Internal Log
Depending on the failure category, you will automatically be taken
by the system from the
411 Current Overview
menu to the appro-
priate menu with the description of the failure.
The method for resolving the failure depends on the failure cat-
egory.
Events in the "external events" failure category are generally
resolved by the installer.
Events in the "internal events" failure category must always be dis-
cussed with Delta Solar Support first before attempting to resolve
the failure.
If events from both categories occur simultaneously, those in the
"internal events" category take priority. In this instance, therefore,
Delta Solar Support should always be contacted first.
