J CHOOSING THE RIGHT TEACHING METHOD
Refer to the following table to select the most suitable sensitivity setting method.
Note: 1. None of the four channels has any output when the E3X-NM (four channels) is in teaching mode (i.e., all the four channels will

ing two to three Fiber Units to more than one E3X-NT (one channel), perform with/without-object teaching, in which case teach-
ing must be performed on a single E3X-NT at a time. Therefore, turn on only the E3X-NT on which teaching is performed. If all
the E3X-NTs are turned on, interrupt the emitters of the Fiber Units on which teaching is not performed.
