8.8  Parameter setting via the teach input

The teach input must be activated� This requires previous configuration via  

IO-Link 

(→ 8.4)

, parameter [ou2] = [tch]

Output OUT2 must be configured as hysteresis function (Hnc or Hno)�  

If the window function is set, an error during teaching results  

(→ 8.8.3 Error during teaching)

Only output OUT2 is available in the teach mode� In the teach mode the 

LEDs indicate the switching status of output OUT2�

8.8.1  Carry out the full adjustment via teach input

 

Fill the tank until the probe tip is completely covered�

 

Apply Ub+ to pin 4 for >2 ��� < 5 s�

The tool which is available for this process is the teach button (accessory)�

 

> LEDs are flashing with2 Hz (

)�

 

> After teaching the LEDs light for 2 s, then the colours change to regular 

operating mode (table 

→ 8.8.2

)�

8.8.2  Changing the output function

Output OUT2 can be changed from "NC" (Hnc) to "NO" (Hno) and vice versa� 

 

Apply Ub+ to pin 4 for >5 ��� < 10 s�

 

> LEDs are flashing, first with 2 Hz (

), after 5 s with a 1 Hz double flashing 

(

)�

 

> After the change the LEDs light for 2 s� Then the colours change to regular 

operating mode (table below)�

 

> After the successful changeover, the LEDs light as follows:

No medium detected

LEDs = yellow (for Hnc)

LEDs = green (for Hno)

Medium detected

LED2 = green (for Hnc)

LED2 = yellow (for Hno)
