SECTION 4: Function

4-3-6 Timing diagrams

4-3-7 Keyboard lock 

With the keyboard lock function, the push buttons on the sensor can be locked to prevent inadvertent modifi-
cation of the settings. 

The lock can be activated and deactivated on the sensor. When the keyboard lock is active, changes can only

be made after the Minus 

 and Plus 

 keys have been pressed simultaneously for 4 seconds. This tem-

porarily suppresses the keyboard locking. If no key is pressed for about 150 seconds, the keyboard lock is
automatically activated again. 

4-3-8 ECO energy saving mode 

In the ECO mode, the display switches off automatically approximately 3 minutes after the push buttons have
been pressed for the last time. 

The display is activated again the next time the push buttons are pressed. Deactivation of the sensor display
reduces the sensor's current consumption by approximately 20 mA. 

4-3-9 Reset 

Reset returns the sensor to the factory default settings.  

4-4 Inputs/Outputs 

In total, the sensor can be operated with a maximum of three inputs/outputs. The functions of the inputs/out-
puts are user determined. 

Connector pin 4 is always defined as output (OUT). 

Connector pin 2 can be set as alarm output (ALARM), as test input (TEST).  

Connector pin 5 can be set as test input (TEST) or OFF. 

4-4-1 Input: Test input TEST

Connector pins 2 or 5 can be set as test input.  

The emitter is deactivated if a signal in the operating voltage range is applied to this input. Depending on the
absence of a detection object the sensor alters it's output,because no light is emitted.
