For that purpose the bar graph and detail indication has to be activated. Now the corre-
sponding channel has to be selected on the display by means of the functional key F1
(<CH>) and then Alarm A1, A2, A3 by means of the functional key F2 (<AL>). The alarm
can now be deleted by means of the functional key F3 (AQUIT). In case of a fault perform
the equivalent procedure.
If relays had been configured as reset able (see chapters 4.2), they can be quit by pressing
the functional key F5. To use this function you have to choose the Bar graph and detail indi-
cation. This function shall be used for acoustic alarms (horn, buzzer) only.
