Alarm display
If the pump detects one or more alarm conditions, LED 1

indicate the type of alarm as shown in the following table. If
more than one alarm is active at the same time, the LEDs only
show the alarm condition with the highest priority. Alarm priori-
ty follows the order of the table.
When no alarm is active, the user interface automatically dis-
plays pump performance.
