The job indicators can be used as large operation indicators by setting
No. 4 of the operation mode switch to the OFF side and connecting the
input (pink) of the emitter to the output (black) of the receiver.

Note:
In order to use the job indicators as large operation indicators, make sure to set
No. 4 of the operation mode switch to the OFF side. If it is set to the ON side, the
job indicator does not light up or blink.

The emission is stopped when No. 4 of the operation mode switch is set
to the ON side and the input (pink) of the emitter is made High (PNP
output type: Low).
Since the output can be turned ON/OFF without the sensing object, this
function is useful for start-up inspection. If the output follows the
application/withdrawal of the test input, the sensor operation is normal,
else it is abnormal.

By setting different emission
frequencies, two units of NA2-N can
be mounted close together, as shown
in the figure on the right. The emission
frequency can be checked by the
number of LEDs lighting up in the
emitting indicator on the emitter.

Place the emitter and the receiver face
to face along a straight line.
After the cables have been correctly
connected, switch the power ON.
Move the emitter in the up, down, left
and right directions, in order to determine
the range of the beam received condition
with the help of the operation indicator
on the receiver. Then, set the emitter at
the center of this range.
Similarly, adjust for up, down, left and
right angular movement of the emitter.
Further, perform the angular adjustment for the receiver also.
Check that the stable incident beam indicator (green) lights up.
Interrupt each beam channel with the actual sensing object, and confirm
that the sensor operates correctly.
Note:
The stable incident beam indicator (green) lights up when all the light beams are
stably received.
