Description of Sensor Functions

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 m st be applied to the TEACH-IN input for at least 1 s. LEDs indicate whether the sensor has recognized 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:

• Analogue value increases with rising distance to object (rising ramp)

• 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

5. Installation conditions

If the sensor is installed at the environment with temperature below 0℃, it should be protected. When mounting the sensor in

a through hole by screw nuts, the sensor need to be fixed at the middle of the mounting thread.
