Operation Mode Selector
AUTO Mode: The sensitivity is automatically adjusted within
a range of approximately 80% to 110% of the
rated sensing distance.
T Mode:
This mode is used when adjusting the
sensitivity of the Sensor. (The output transistor
does not operate in this mode.)
RUN Mode: This mode is used for the normal operation of
the Sensor.
Resolution Selector
If the E2CY often has a teaching error when detecting
fine-tuning differences, set the resolution selector to FINE.
The response speed will drop but improvement in the
sensing accuracy of the E2CY can be expected.
Output Mode Selector
Used to select the transistor mode (NPN open collector output).
NO: Normally open output
(Output transistor will turn ON if a sensing object is
present.)
NC: Normally closed output
(Output transistor will turn ON if a sensing object is
not present.)

SELF-DIAGNOSTIC FUNCTION
The output transistor of self-diagnostic output will turn ON in the following cases.
1.
Sensor cable disconnection
The self-diagnostic output will turn ON approximately 105 ms after the sensor cable disconnects.
2.
Sensor cable short-circuit
The self-diagnostic output will turn ON approximately 105 ms after the sensor cable short-circuits.
3.
Control output short-circuiting
The self-diagnostic output will turn ON if excessive current flows to the load due to load wire short-circuiting.
4.
Internal memory error
When the E2CY is turned ON in RUN or TEACH mode, the self-diagnostic output will turn ON if the teaching status of the E2CY is not
stored properly in the internal memory.
