* In the following sections installation and setup are described using the example of the type
with front lens The functions of the units with side lens are identical
Secure the receiver (OJELxx) to a bracket
►
Align the transmitter (OJSLxx) to the receiver and secure it in the same way
►
Maximum range is only possible with precise alignment
Mount the unit so that the mounting position cannot change (avoid high
►
vibrations!)
Laser units with a very small light spot diameter are highly focussed; the
slightest change in the mounting position will result in misalignment
The optical position of the laser beam may deviate slightly from the mechanical
axis Therefore we recommend using the fine adjustment units E21225 (front lens)
or E21226 (side lens) when mounting the laser units
