Display- and Operating elements
Fig. 1: Display- and Operating elements
The green stability LED serves to indicate the level of the
received input signal (see fig.3) and to make alignment of
the photoelectric sensors easier.
The red LED shows the output state: he goes on when
the output is ON and goes off when the output is OFF.

Please note the following:
–When installing the photoelectric switches adjacently,
keep them apart from each other, or install a light
barrier to prevent light interference. Pay attention to
reflected light from the flor or wall.
–Make sure that fluorescent light does not
enter into the receiver of the photoelectric
switch. Fluorescent lamps may effect the
photoelectric switch operation depending on
its location.
–Do not strike the photoelectric switches
when installing, otherwise the waterproof
characteristics will be impaired.
Photoelectric Sensor
DIN rail/35
The green stability display illuminates in the "safe" range,
where the input energy is at least 30% over or under the
threshold energy (see fig. 3). The threshold energy at
which a signal change is effected, is defined as 100%.
The light/dark switching mode can be selected by using
different cable combinations (see fig. 5).
Safety advice
These Photoelectric Sensors are not suited for safety
related applications.

The cable should not be run in the same wire duct with
other power supply, motor or electromagnetic lines
because induction noise will cause malfunction or
damage to the photoelectric switch.

Use the photoelectric switch within the rated power
voltage.
Do not use the photoelectric switch under conditions
exceeding the rated operating temperature, vibration
resistance and shock resistance.
Installing the slit (optional in emitter/receiver)
Slits are used to detect small objects or to increase the
accuracy of detecting positions.
By using the slit aperture you get a reduced sensing
range:
Slit width 0.5 mm 1 mm 2 mm
Range 0.5 m 1.0 m 2.0 m
Object size > 0.5 mm > 1 mm > 2 mm
Test input on Emitter DC
The TEST-function provides a remote check of the thru
beam type and serves as a preventative measure.
The TEST-input (TEST+ and TEST–) interrupts the light
pulses from the emitter and allows the function of emitter
and receiver to be checked.
When using TEST+, TEST–must be at 0 V. When using
TEST–, TEST+ must be at 10...30 V.
The receiver output must switch each time when a
voltage of 10...30 V DC (TEST+) or 0 V (TEST–) is present
on the test input.
Contamination or maladjustment on the optical axis
causes the emitter signal to reach the receiver only
weakly, if at all.Therefore the output will not switch even
though the test input is activated.
Alarm output in Receiver
The receiver is equipped with an alarm output (PNP open
collector, 30 mA). It acts as a warning signal when the
function is affected by contamination or mechanical
maladjustment. The alarm output is activated when the
receiver signal is in the alarm range for at least
3 seconds.

Cleaning
The lens is made of acrylic resin. Clean the lens with
alcohol or a dry soft cloth. Do not use organic solvent
such as thinner.
Photoelectric Sensor
Optical alignment
1. Set the sensitivity trimmer to max.: the
green LED must be on.
2. When the object to be detected is in
the sensing range, turn the sensitivity
trimmer clockwise from min. position
until the red output indicator is on
(point a).
3. When removing the object, the red
output indicator goes off. Turn the
sensitivity trimmer clockwise until the
red output indicator is on again
(point b) till background is detected.
When the background is not detected,
point b is at max.
4. Adjust sensitivity trimmer at point c
(middle point between a and b) to get
the best sensitivity. In this position the
green LED must be on.

The two LED's are usefull for the sensor alignment. The
action of the red LED will change according to the mode
selected (see fig. 3).
Adjusting the emitter/receiver
1. Place the emitter/receiver within the operating
distance. The sensitivity trimmer SENS is set to max.
(see fig. 1).
2. Move the emitter/receiver to make both LED on: light
is received.
3. To optimize the positioning get firstly the red output
LED switching (unstable function) then the green LED
on again (stable function).
Adjusting the polarized retroreflective sensor
1. Place the reflector and the sensor within the operating
distance. The sensitivity trimmer SENS is set to max.
(see fig. 1).
2. Move the sensor to make both LED on: light is
received.
3. To optimize the positioning get firstly the red output
LED switching (unstable function) then the green LED
on again (stable function).
Adjusting the diffuse reflective sensor
–Place the reflector and the sensor within the operating
distance.
–Position the object in front of the sensor and adjust
the sensitivity following the herebelow instructions.
This procedure is for Light On pulse.
For Dark On, on and off operations of the indicator are
reversed.
