OPTICAL AXIS ADJUSTMENT (FLASHING FUNCTION)
This function can be used with through-beam (E32-T
) or retroreflective (E32-R
) 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.
Set the mode selector of the E3X-N
to TEACH. The flashing function of E3X-N
will be activated when the optical axis of the fiber
heads are divergent and light value decreases by approximately 10% of the maximum value. At this time, the tip of the emitting fiber will
start flashing and the built-in buzzer will beep. In aligning the fiber cables, the peak light value will be memorized by the E3X-N
.
This peak value will be reset if the mode selector is switched to RUN then back to TEACH or power is interrupted. This peak value will not
decrease. Therefore, if alignment is first done at close range, the flashing function will not work at longer distances. Do not press the
teaching button before or while adjusting the optical axis, or the flashing function will not operate.
