## **Adjustment** 

## **Sensitivity adjustment, with static object** 

1. Line up the sensor with the object. Yellow LED and green LED are ON. 

2. Press the button for 3 s until both LED’s flash simultaneously (the first switching point is stored). 

3. Place the object outside the detection area. 4. Press the button for 1 s. 

   - a) The green LED flashes and stays ON: the second switching point is stored, and the sensor is ready to operate. 

   - b) Both LED’s flash simultaneously: the sensor cannot detect the object, no switching points are stored.

- **Programming of make and break switching function** 1. Press the button for 13 s. **13 s** Both LED’s flash alternately. 

   - Release the  button: the green LED flashes. 

2. 

3. While the green LED flashes, the output is inverted each time the button is pressed. This is indicated by the yellow LED. 

   - When the button is not pressed for 10 s, the current output function is stored. 

   - The sensor is now ready for operation. 

## **Default setting** 

1. No object in the detection area: Press the button for 3 s, until both LED’s flash simultaneously. **3 s** 

2. No object in the detection area: Press the button for 1 s. **1 s** The sensor is set to maximum sensitivity. 

**NB!** The Teach Input (2 WH) will work similarly to the push button, active High. 

## **Sensitivity adjustment, with only one object** 

1. Line up the sensor with the object. Yellow LED and green LED are ON. 

2. Press the button for 3 s until both LED’s flash simultaneously (the first switching point is stored). 

3. Leave the object in the detection area, press the button for 1 s. The green LED flashes and stays on: the second switching point is stored, and the sensor is ready to operate. 

## **Sensitivity adjustment, with a running process** 

1. Line up the sensor with the object. Green LED is ON. At this stage the status of the yellow LED can be ignored. 

2. The running process must be the only “object” within the detection area. Press the button for 3 s until both LED’s flash simultaneously. 

   - **3 s** 

3. Press the button for at least the duration of one process cycle. 

## **1 cycle** 

- a) The green LED flashes and stays ON: both switching points have been stored, and the sensor is ready to operate. 

- b) Both LED’s flash simultaneously: the sensor cannot detect the object, no switching points are stored.
