1. 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 or +U to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1s. LEDs indicate whether the sensor has recognized the target during the TEACH-IN procedure. The lower evaluation limit A1 is taught with -U, A2 with +U.
 
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

6. LED Displays
 

Displays in dependence on operating mode	Red LED	Yellow LED
Teach-In evaluation limit
Object detected	Off	Flash
No object detected	Flash	Off
Object uncertain (Teach-In invalid)	On	Off
Normal mode (evaluation range)	Off	On
Fault	On	Previous state
