E3S-A
Self-Diagnostic Function
To switch the emission off, short-circuit the gray (pink) and the
black (blue) cords of the emitter of the E3S-AT or the
E3S-AR with the NPN output feature. For the E3S-AR with
the PNP output feature, short-circuit the gray (pink) and the red
(brown) cords.
NOTE: IEC colors are shown in parentheses.
With this function, the E3S-A sensor checks changes in environmental conditions (especially a change in the ambient temperature) and
self-diagnoses the resistance against the changes. The result is shown by the indicators or an output signal.
