, so they can be read repeatedly without clearing the values.
ErrorStatus1
through
ErrorStatus8
can all be cleared by writing 0 to any of them. They are
not
preserved across
power failures.
ErrorStatus1
through
ErrorStatus8
are generally best used when a person will
be looking at the values in real time, because they provide a visual history of recent errors and
events and will not be cleared when they are read.
The following lists many of the error and status code values. For any not listed or those marked
“ERROR” contact technical support.
