Optical Axis Adjustment Method - Mitsubishi Electric AJ65BT-RPI-10A User Manual

4.6.2 Optical axis adjustment method

The optical axis is adjusted in the following steps.
(1) Place the modules face-to-face and align the module axes
approximately.
(2) While observing the operation indicator LEDs of the module (A
module), change the angle of the other module (B module) in
vertical or horizontal directions to obtain a proper angular range in
which the operation indicator LED, R3 turns on.
Note that, if A module is moved at this time, the reference axis
cannot be fixed and proper adjustment will be difficult.
(3) Check the operation indicator LEDs on both modules.
Confirming the LEDs on one module only may not adjust the other
optical axis.
