Page 11: Self-Diagnostic Function
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. Amount of Green indicator... - Page 12 There is no need to adjust the sensitivity of each photoelectric sensor in- dividually.
