Alarm display
If the pump detects one or more alarm conditions, LED 1 changes
from green to red. When an alarm is active, the LEDs 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 priority follows
the order of the table.
When no alarm is active, the user interface automatically dis-
plays pump performance.
