11.1 Fault indication
When a fault occurs, the LCD display lights up permanently, the collective fault signal is ac-
tivated and the fault is shown on the LCD display (error code number).
A faulty pump is indicated on the main screen by a flashing status symbol for the corre-
sponding pump.
• Acknowledge the fault in the menu: Interaction/Communication→Alarms→Acknow-
ledge.
11.2 Fault memory
The control device stores the last 13 errors in the fault memory. The fault memory works
according to the first in/first out principle. The frequency of error messages is displayed.
The overview of the currently existing alarms can be displayed.
• Call up the fault memory via the menus:
– Interaction/Communication→Alarms→Current alarms
– Interaction/Communication→Alarms→Alarm history
– Interaction/Communication→Alarms→Alarm frequency
