3.4 Function "process propert." (004)
Use this function to adapt the device reaction to the filling speed in the tank. The setting impacts
on an intelligent filter.
Selection:
•standard
• fast change
• slow change
• test:no filter
3.5 Function "end of probe" (030)
Use this function to select the polarity of the probe end signal. If the probe end is uncovered or in
an insulated attachment, there is a negative probe end signal.
The signal from the probe end is positive if the attachment is grounded.
Only the setting "free " is permitted for the FMP41C/FMP43.

Application: For all normal applications, bulk
solids and fluids at low to
medium filling speed and suffi-
ciently large tanks.
Small tanks, primarily with flu-
ids, at high filling speeds.
Applications with strong surface
movement, e.g. caused by stir-
rer, primarily large tanks with
slow to medium filling speed.
Shortest reaction time:
• For test purposes
• Measurement in small tanks
at high filling speeds, if "rapid
change" setting is too slow.
