Status Indicators
All elements and mainframes have status indicators. Status indicators that inform the operator
of a problem are called error indicators. Indicators that tell the user which elements are
communicating with a display element are called active indicators.

Indicators.
The ERR (error) light indicates that the element has an error condition.
If
the element is a slave, the error lights of both the slave and its master indicate the error
condition.
The error lights go out when the error condition no longer exists and it has been
reported. Error conditions are reported either by an automatic error reporting routine, or when
the operator presses the
