- Page 9 E3X-N E3X-N J REMOTE TEACHING FUNCTION The remote teaching function of the E3X-Nj should be used for initial teaching. The method of remote teaching is the same as that of sensitivity setting. In remote teaching, instead of pressing the teaching button, teaching is performed with a remote teaching input signal.
- Page 10 E3X-N E3X-N J OPTICAL AXIS ADJUSTMENT (FLASHING FUNCTION) This function can be used with through-beam (E32-Tj) or retroreflective (E32-Rj) fiber cables. Its main purpose is to achieve the maxi- mum gain. If the customer finds difficulty in this method or maximum gain is not required, align the cables in RUN mode (as normal) using the output indicator as an indicator for alignment.
