NOTE
1. The figure shows the status of the emitter/receiver indicators during
operation when you are using a PNP output. When you are using an NPN
output, the NPN indicator lights up orange.
2. Since the color of the operation indicator changes according to whether the
control outputs (OSSD 1, OSSD 2) are ON or OFF, the operation indicator on
the light curtain is marked 'OSSD'.
