ADJUSTMENTS

٨
Adjust the sensitivity, observing the
operation indicator (red). However,
since the condition for lighting up of
the indicator depends on the com-
bination of the sensing condition
and the selected operation Light-
ON / Dark-ON, verify if from the ta-
ble on the light.
For the sensor with timer, be sure to adjust in the state where
the timer function is not operating. As shown in the figure right,
set the timer operation mode switches to '3' and '4' respectively.

Set the operation mode switch to the Light-ON mode position (LIGHT ON side).
Placing the sensor and the reflector face to face along a straight line, move the
reflector 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
(red). Then, set the reflector at the cen-
ter of this range.
Similarly, adjust for up, down, left and
right angular movement of the reflector.
Further, perform the angular adjustment
for the sensor also.

rections, in order to determine the range
of the light received condition with the
help of the operation indicator (red).
Then, set the emitter at the center of

Similarly, adjust for up, down, left and

Turn the sensitivity adjuster fully counterclockwise to
the minimum sensing range position, MIN.
Place an object at the required distance from the sen-
sor, turn the sensitivity adjuster gradually clockwise,
and find out point where the sensor changes to the
light received condition.
Remove the object, turn the sensitivity adjuster fur-
ther clockwise, and find out point where the sensor
changes to the light received condition again with on-
ly the background.
When the sensor does not go to the light received
condition even if the adjuster is fully turned clock-
wise, point is this extreme point.
The optimum position to stably detect objects is the
center point between and .
RETROREFLECTIVE TYPE SENSOR WITH
POLARIZING FILTERS
9
٨ If a shiny object is covered or wrapped with a transparent film, such as those
described below, the retroreflective type sensor with polarizing filters may not be
able to detect it.
In that case, take the following measures given below.
<Example of sensing objects>
Can wrapped by clear film
Aluminum sheet covered by plastic film
Gold or silver color (glossy) label or wrapping paper
<Measures>
Tilt the sensor with respect to the sensing object while fitting.
Reduce the sensitivity.
Increase the distance between the sensor and the sensing object.
TIMER FUNCTION (Only timer incorporated models)
10
٨ The timer incorporated models have three types of convenient timer functions in
addition to the normal operation.

How to mount
SLIT MASK (OPTIONAL)
(Exclusively for thru-beam type sensor)
11
٨ With the slit mask (OS-VF-غ), the sensor can detect a small object.
However, the sensing range is reduced when the slit mask is mounted.
Check the directions of the slit mask and press it to the
lens surface till you feel a click.
