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
standard fast change
Small tanks, primarily with
fluids, at high filling speeds.
Dead time: 2 s
Rise time: 5 s
Dead time: 1 s
Rise time: 3 s
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.
Selection:
• free
• tie down isol.
• tie down gnd.
slow change
Applications with strong surface
movement, e.g. caused by
stirrer, primarily large tanks with
slow to medium filling speed.
Dead time: 6 s
Rise time: 40 s
Dead time: 3 s
Rise time: 25 s
Commissioning
test:no filter
Shortest reaction time:
• For test purposes
• Measurement in small tanks
at high filling speeds, if "rapid
change" setting is too slow.
Dead time: 1 s
Rise time: 0 s
Dead time: 0,7 s
Rise time: 0 s
