6.5.8
Detect unauthorized operating states
Following unauthorized operating states can be determined
based on the values supplied by the device:
operational state
Condition
Dry running / inadequate lubrication
P << P0
Closed pressure slide
P ≤ P0
Flow rate too low
P ≤ Pmin
Conveyor demolition by gas
P << P0
Conveyor demolition by cavitation (Only
with full cavitation)
P << P0
Cavitation due to high delivery rate (Pmax
must be specified)
P > Pmax
slide bearing damage
P > Pmax
Tank run dry
P << P0
coupling demolition
P >> Pmax
CAUTION
For local or foreign media flushing, a lack of lubrication
or dry-running of the plain bearings in the pump not
be recognized.
