Checking through the visor
Check the alignment of the optical axis using the visor on the right-hand side of the SR-unit
enclosure and by making adjustments on the device flange.
Visor The visor indicates the alignment of the optical axis between the SR-unit and the reflector
using a 5 x 5 LED matrix. The LEDs light up to represent the position of the light beam on
the reflector. The crosshairs show three fields for alignment purposes.
▸ Adjust the optical alignment (as shown in
“Aligning the optical axis“) by adjusting both
screws on the device flange (L alignment) and observe the light position of the LEDs.
Horizontal adjustment causes the light spot to shift horizontally on the visor and vertical
adjustment causes a vertical shift. Alignment is correct when the lit LED is located within
the valid field within the cross hairs, or is completely within the inner ring marking of the
cross hairs.
