Stability Indicator
●
The stability indicator (green) lights up when the incident light intensity has sufficient
margin with respect to the operation level.
Incident light intensity level is such that the stability indicator light up, stable sensing can
be done without the light received operation and the light interrupted operation being af-
fected by a change in ambient temperature or supply voltage.

1.
Place the emitter and the receiver face to face along
a straight line, move the emitter in the up, down, left
and right directions, in order to determine the range
of the light received condition with the help of the
operation indicator (orange). Then, set the emitter at
the center of this range.(Note 1)
2.
Similarly, adjust for up, down, left and right angular
movement of the emitter.
3.
Further, perform the angular adjustment for the
receiver also.
4.
Check that the stability indicator (green) lights up.
(Note 2)
(Note1) : When using the narrow beam type
EX-1
□
S
□, if the beam axes are out of alignment, check to see if the
emitter and the receiver are facing each other in a straight line.
(Note2) : In case of
EX-15
/
17
, adjust the beam axis after turn the operation mode switch to “
L-ON
”.
After it, switch the operation mode by adopting the operation.
