Section 2-4
When the abnormal current is detected and branch output is cut off, the error
code (A11) and present current are displayed alternately on the seven-seg-
ment display and the Tripping Alarm Output (TRP) is turned OFF.
The status indicator of the branch output that was cut off will flash red.
To clear the error, eliminate the cause of the error, and then press the Reset
Key. Once an error has been reset, another reset operation cannot be per-
formed for at least 15 seconds.
