E3S-A/B
With this function, the E3S-A/-B checks changes in environmental conditions (especially a change in the ambient temperature) and self-diag-
noses the resistance against the changes. The result is shown by the indicators or an output signal.
To switch the emission off, short-circuit the pink and the blue cords
of the emitter of the E3S-ATj or the E3S-ARj with the NPN output
feature. For the E3S-ATj or the E3S-ARj with the PNP output fea-
ture, short-circuit the pink and the brown cords.
