The fault occurrences can be browsed backwards by means of the

-key.
The first number in the fault memory shows the number of the fault occurrence, the second number
after the point – the fault number (1 … 32). After the colon, the fault short form text is displayed. The
date and time of the fault follow in the second line. It is to be observed that several fault occurrences
with the same date/ clock time are possible, if the faults have occurred within the same minute.
