9 Operation

After every power on all LEDs light and go out again step by step (during this time 

the output is closed if configured as normally open)� The unit is then ready for 

operation�
In case of power failure or interruption all settings remain�

Operating indicators 

         

Green LED bar: Current flow within the representa

-

tion range�

Indication of the switch point (SP):

- LED orange: output closed.

- LED red: output open.

         

LED 9 flashes: current flow above the

representation range�

         

LED 0 flashes: current flow far below the represen

-

tation range�

Interference indicators

         

         

Short circuit at the switching output:

The operating indicator and red LEDs light 

alternately� 

If the short circuit has been rectified, the unit im-

mediately passes into the normal operating state�

The current operating state is displayed�

Display OFF

(no LED lights):

Operating voltage too low (< 19 V) or failed�

Ensure a correct voltage supply�

10 Maintenance

Recommended maintenance: 

 

Check the sensor tip for build-up from time to time� 

 

Clean it using a soft cloth� Stubborn build-up (e�g� lime) can be removed using 

a common vinegar cleaning agent�
