Self-diagnostic Function
The self-diagnostic output transistor will turn ON in the following cases. (The output will turn ON for any of these conditions individually.)
(1) Sensor open circuit: Transistor will turn ON the instance there is an open circuit for the Sensor (including the cable).

Note: When the E2C-X2A Sensor is used, 93% is 96% and 107% is 104%.
* The self-diagnostic output may turn ON if the sensing objects moves a low
speed. In actual application, include an ON-delay timer circuit or other
suitable measure.
(2) Detection: The output will turn ON if a sensing object is within 93% to 100% of the sensing distance continuously for 0.3 s or longer (e.g.,
for sensing object position offset).
(3) No detection: The output will turn ON if a sensing object is within 100% to 107% of the sensing distance continuously for 0.3 s or longer (e.g.,
when background is influencing detection).
Indicators
• The detection indicator lights when a sensing object approaches the
sensing distance to indicate that a sensing object has been detected.
• The stability indicator lights when the sensing object approaches within
93% of the sensing distance or moves away from 107% of the sensing
distance to indicate a stable sensing or non-sensing condition.
