Adjusting the evaluation limits
The ultrasonic sensor features an analogue output with two teachable evaluation limits. These are set by applying the supply voltage -U
limit A1 is taught with -U
Two different output functions can be set:
1. Analogue value increases with rising distance to object (rising ramp)
2. Analogue value falls with rising distance to object (falling ramp)
TEACH-IN rising ramp (A2 > A1)
- Position object at lower evaluation limit
- TEACH-IN lower limit A1 with - U
- Position object at upper evaluation limit
- TEACH-IN upper limit A2 with + U
TEACH-IN falling ramp (A1 > A2):
- Position object at lower evaluation limit
- TEACH-IN lower limit A2 with + U
- Position object at upper evaluation limit
- TEACH-IN upper limit A1 with - U
or +UB to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1 s. The evaluation

Installation conditions
If the sensor is installed at places, where the environment temperature can fall below 0 °C, for the sensors fixation, one of the
mounting flanges BF 12 or BF 5-30 must be used. In case of direct mounting of the sensor in a through hole, it has to be fixed at
the middle of the housing thread.
Note
If the sensor is used in an environment with strong electromagnetic interference, we recommend non-conductive mounting. For this, use
the accompanying plastic nuts or the BF12 mounting flange.
Please observe proper application when using the accompanying plastic nuts. The hole for the sensor must be ≥ 14 mm.
