1.1 Pending Errors
1.1.5
Provides the list of active errors with their status (active, acknowl
-
edged). If an active error is acknowledged, the alarm relay is active
again. Cleared errors are moved to the Message list.
1.2 Message List
1.2.1
Shows the error history: Error code, date / time of issue and status
(active, acknowledged, cleared). 65 errors are memorized. Then the
oldest error is cleared to save the newest error (circular buffer).
