Description of Device Parameters Liquipoint FTW33
38 Hauser
Description To prevent rapid switching back and forth when values are close to the switch point
"SP1"/"SP2" or switchback point "rP1"/"rP2", a delay in the range of 0.3 to 60 seconds, to one
decimal place, can be set for individual points.
If the measured value leaves the switching range during the delay time, the delay time
starts again from scratch.

dS1 Set time for which the specific switch point must be reached continuously without interruption until an
electrical signal change takes place.
dR1 Set time for which the specific switchback point must be reached continuously without interruption until an
electrical signal change takes place.
Switch on value Last value selected prior to switching off.
Options No selection. The user is free to edit the values.
Input range 0.3 to 60 s
Factory setting 0.5 s (Switching delay time dS1/dS2)
1.0 s (Switchback delay time dR1/dR2)
Output 1/2 (OU1/OU2)
Navigation Application → Output Switch 1/2 → Output 1/2 (OU1/OU2)
Description Hysteresis: Determining whether sensor is free or covered.
Switch on value Last function selected prior to switching off.
Options • Hysteresis normally open (MIN)
