## **Preferences** 

## **Teach-In:** 

You can use the rotary switch to select the relevant switching threshold A and/or B for teaching in for switching output **Q1** . The yellow LEDs indicate the current state of the selected output. 

To store a switching threshold (distance measured value), press and hold the "SET" button until the yellow and green LEDs flash in phase (approx. 2 s). Teach-In starts when the "SET" button is released. 

Successful Teach-In is indicated by alternating flashing (2.5 Hz) of the yellow and green LEDs. 

An unsuccessful Teach-In is indicated by rapidly alternating flashing (8 Hz) of the yellow and green LEDs. 

After an unsuccessful Teach-In, the sensor continues to operate with the previous valid setting after the relevant visual fault signal is issued. 

Different switching modes can be defined by teaching in the relevant distance measured values for the switching thresholds A and B:

A leer B leer<br>B A<br>A > B B > A<br>B A A B<br>**----- End of picture text -----**<br>


Every taught-in switching threshold can be retaught (overwritten) by pressing the SET button again. 

Pressing and holding the "SET" button for > 5 s completely deletes the taught-in value. The yellow and green LEDs go out simultaneously to indicate that this procedure has been completed. Minimum and maximum values for the analog output **Q2** are taught in in the same way as those for the switching output: The following values apply: A = 4 mA B = 20 mA This provides three different options for operation: **A < B -> rising slope A > B -> falling slope** 20 20 4 4 A B B A

## **Reset to default settings:** 

Factory setting for switching output Q1: 

- Switching output inactive 

Factory setting for analog output Q2: A = 200 mm 

B = 5000 mm 

**==> picture [41 x 33] intentionally omitted <==**

Value B cannot be deleted 

The "zero start point" operating mode can be obtained by deleting value A 

- Set the rotary switch to the "RUN" position 

- Press and hold the "SET" button until the yellow and green LEDs stop flashing in phase (approx. 10 s) 

- When the green LED lights up continuously, the procedure is complete. 

## **Error messages:** 

- Short circuit: In the event of a short circuit at the sensor output, the green LED flashes with a frequency of approx. 4 Hz. 

- Teach error:In the event of a teach error, the yellow and green LEDs flash alternately with a frequency of approx. 8 Hz. 

**==> picture [33 x 33] intentionally omitted <==**

## _**Note!**_ 

The difference in the taught-in distance measured values for switching thresholds A and B must be greater than 20 mm. 

If the difference in the taught-in measured values is the same as or smaller than the set switching hysteresis, the sensor will visually signal an unsuccessful Teach-In. The last distance measured value that was taught in will not be adopted by the sensor. 

Select a new distance measured value for switching threshold A or B with a greater difference between the switching thresholds. Teach in this distance measured value on the sensor again. Switching threshold A can be deleted or set to a value of zero. 

(E.g., when setting the "zero start point" curve). 

However, switching threshold B can neither be deleted nor set to a value of zero. 

## **Laser notice laser class 2** 

- The irradiation can lead to irritation especially in a dark environment. Do not point at people! 

- Caution: Do not look into the beam! 

- Maintenance and repairs should only be carried out by authorized service personnel! 

- Attach the device so that the warning is clearly visible and readable. 

- Caution – Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
