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 unsuccessful,
the teaching indicator (orange) will flash, in which case change the position
of the object and the sensing distance that have been set and repeat from
step 3.
Light is received.
5. Set the mode selector to RUN to complete the sensitivity setting on the E3X-
MA11.
• This function enables the user to easily adjust the light axis of a thru-beam fiber
with the light source flashing.
• If the light projection fiber head axis and the light reception fiber head axis do
not agree with each other, and the amount of light received becomes 90% of
the peak value or less, the flashing function of the E3X-MA11 will operate. The
E3X-MA11 retains the peak value when the mode selector is set to SET so that
the axes of the fiber heads can be easily adjusted to agree with each other.
When the axes agree, the tip of the fiber for light emission will be lit.
• If a Remote Console is connected to the Sensor Unit, the buzzer of the Remote
Console will beep intermittently when the flashing function starts operating.
The buzzer will stop beeping when the axes agree and the tip of the fiber for
light emission is lit.
• Teaching is possible by pressing the teaching button while the flashing function
is operating.
Fiber for light emission
There are three sensitivity adjustment methods. Choose the most optimum
method according to the application.
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.
