Illuminator, self-adjusting 

(423011-9901) 

Fig. 10  Keys for setting offset values for the adjustment 

of lamp arc and mirror image 

On the self-adjusting illuminator, the position 

of the lamp arc and its mirror image may be 

individually customized, if required, by the 

adjustment of offset values. 

After the automatic adjustment (see Section 

3.4), LED key (Fig. 9/1) lights permanently 

green. 

By briefly pressing the recessed keys on the 

rear side of the illuminator housing (Fig. 10), 

the motors for arc positioning are moved in 

steps to the left, right, top or bottom within a 

limited range.  

During positioning, the LED key flashes 

alternately green and orange. If you do not 

press any key for more than 20 seconds, the 

currently set value will be stored. 

Not every key pressure will directly lead to a 

movement of the motors: The intensity change 

detected by the sensors must exceed a certain 

threshold, before the position is readjusted. 

Therefore, it may be necessary to press a key 

repeatedly. 

To reset the factory adjustment, the top button 

of the keypad must be pressed for ten seconds.
