ALIGNMENT OF SENDER AND RECEIVER UNITS
To complete the installation of the AOPD and to ensure proper function-
ing of the protective device, the sender and the receiver must be ac-
curately aligned. Perfect alignment is achieved when each emitted light
beam reaches its corresponding optical element on the receiver unit.
This means positioning the two units so that the maximum amount of
emitted light energy reaches the receiver element. The specified maxi-
mum optical aperture angle (
±
2.5
°
) requires accuracy in aligning the
two units before they are firmly fixed in place.
During the alignment process, the OSSD output signals of the protec-
tive device must not have any effect on the machine. Make sure the
machine remains switched off.
The alignment process is facilitated by the dedicated orange LED indi-
cator on the sender unit. Figure 27 shows how the LED behaves during
the alignment process.
