Self-diagnostic Function
The output transistor of self-diagnostic output will turn on instantly if the E2C detects one of the following events.
1. Sensor wire burnout
2. The operation indicator is ON for 0.3 s or more while the sensing object is at 93% to 100% of the sensing distance. This will occur if the
sensing object is in the wrong position, for example.
3. The operation indicator is OFF for 0.3 s or more while the sensing object located at 100% to 107% of the sensing distance. This will occur
if the Sensor is influenced by the background of the sensing object, for example.

Note: 1. If more than two Sensors with the same diameter and length cable are closely mounted side by side, set the switch to a value that is
1 m dif ferent from the actual length. Except for the E2C-C20MA, this method can protect the sensors from mutual interference.
2. Set all the pins of the switch to the left if the E2C-CR5B is used in combination with the E2C-AM4A or E2C-AK4A.
