Long Range Ultrasonic Module Distance Measuring Transducer Sensor
Technical parameters:
Adjusting the evaluation limits
The ultrasonic sensor features an analogue output with two teachable evaluation limits. These are set by applying the supply
voltage -UB or +UB to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1 s.
indicate whether the sensor has recognised the target during the TEACH-IN procedure. The lower evaluation limit A1 is taught
with -UB, A2 with +UB.
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)
Evaluation limits may only be specified within the first 5 minutes after
Power on. To modify the evaluation limits later,
the user may specify the desired values only after a new Power On.
TEACH-IN rising ramp (A2 > A1)
- Position object at lower evaluation limit
- TEACH-IN lower limit A1 with - UB
- Position object at upper evaluation limit
- TEACH-IN upper limit A2 with + UB
TEACH-IN falling ramp (A1 > A2):
- Position object at lower evaluation limit
- TEACH-IN lower limit A2 with + UB
- Position object at upper evaluation limit
- TEACH-IN upper limit A1 with - UB
Default setting
A1: unusable area
A2: nominal sensing range
Mode of operation: rising ramp
