Self-diagnostic Function

With this function, the E3S-A 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.

External Diagnostic Input Function

To switch the emission off, short-circuit the pink and the blue cords of the emitter of the E3S-AT or the E3S-AR with the NPN output feature. For the E3S-AT or the E3SAR with the PNP output feature, short-circuit the pink and the brown cords. With this function, the operating status can be checked before operation.
