If you are going to re-set an activated alarm proceed in the way as has been
explained before, except the fact that the times without insulation faults are
summarized. This is clearly shown in the diagram below:

If an insulation fault occurs, a bar graph is displayed on the screen showing the
elapsed time of the fault. The bar graph appears in the last line of the LC
display whilst the other information and the actual time disappear.
Note: The bar graph indication of the time elapse is only displayed during
setting of alarm not during resetting of alarm.
