Switching the Novexx sensor - NC/NO
This light sensor is equipped with a push-pull output
stage, thus, the two states are called NO (normally
open) and NC (normally closed).
Default setting: NC
Switching between NC/NO:
Press the button [40A] for at least 6 s, until the status
LEDs [40B] flash 2x.
Finding out the current setting:
Move some label material through the sensor fork
and watch the LEDs.
