4-1-2 E3C-MA11 Photoelectric Module
Sensitivity Adjustment There are three sensitivity adjustment methods. Choose the most optimum
method according to the application.
Maximum Sensitivity
Setting
1,2,3... 1. Set the mode selector to SET. When using a thru-beam fiber sensor, adjust
the optical axis using the flashing function of the thru-beam fiber sensor.
2. Press the teaching button for 3 s minimum. The teaching indicator will turn
from orange to green in 3 s.
3. Set the mode selector to RUN to complete the maximum sensitivity setting
of the E3C-MA11.
Note The maximum sensitivity of the Sensor Unit can be automatically set regard-
less of the set distance or light reception.
Teaching without a
Sensing Object (Only for
Diffusive Reflective
Sensor)
If any background object exerts an influence when setting the maximum sen-
sitivity on the ECX-MA11, try the following method.
1,2,3... 1. Locate the sensor head in the sensing range of the sensor.
2. Set the mode selector to SET.
3. Press the teaching button. The teaching indicator (orange) will be lit.
4. Set the mode selector to RUN. If teaching is successful, the stability oper-
ation indicator (green) will be lit. If teaching is unsuccessful, the stability
operation indicator will flash. In this case make sure that the sensor cable
is connected securely, and then change the sensing distance that has
been set and repeat from step 2.
Note The sensitivity of the E3C-MA11 is set to maximum if teaching is performed
with very little light or if the sensor head is not located within the sensing dis-
tance. If stable detection of objects is not possible after teaching, try teaching
with a sensing object as described in the following.
Teaching with a Sensing
Object
Teaching with a sensing object is recommended if delicate sensing operation
is required.
1,2,3... 1. Locate the sensor head in the sensing range of the sensor.
2. Set the mode selector to SET. When using a thru-beam fiber sensor, adjust
the optical axis using the flashing function of the thru-beam fiber sensor.
3. Locate the object at the sensing position and press the teaching button.
The teaching indicator will turn orange.
4. Move the object and press the teaching button. If teaching is successful,
the teaching indicator will turn from orange to green. If teaching is unsuc-
cessful, the teaching indicator (orange) will flash, in which case change the
