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 incident light 1.2 or more 1.0 to 1.2 0.8 to 1.0 Green indicator Stable operating state with incident light: Stable operation is expected in the rated temperature range with the green indicator ON.
The sensor is normal if the control output varies when the self-diagnostic external input is ON and OFF. The sensor is abnormal if the control output does not vary when the self-diagnostic external input is turned ON or OFF.
Turbo Function (Turbo Switch) With Turbo Switch ON The turbo function is effective with the turbo switch pressed, and the function is reset automatically when released. Normal Operating Condition E3S-A With the turbo function switched ON, the light spot is visible even at a distance of 20 cm, making it easy to check the sensing position and the angle of the optical axis. 1.
