Indicator LEDs in RUN mode
Green LED ON: Power OK
Green LED Flashing: Signal strength close to
switching threshold
Yellow LED ON: Outputs conducting
Yellow LED OFF: Outputs not conducting
AID™ (Alignment Indication Device)
In teach mode, the bicolor indication LED
flashes red at a rate proportional to the received
signal strength. This indicates the best optical
alignment.
Remote programming
The grey teach-wire (connector pin 5) permits
teaching the sensor the light and dark
conditions using a remote switch or a PLC.
Connecting it to DC common (–) has the same
effect as pushing the teach button. Pulses and
the intervals between them must be between 40
and 800 ms long.
Disabling the teach button
The teach button can be disabled (locked) or
enabled (unlocked) by pulsing the remote teach-
wire 4 times. Pulses and the intervals between
them must be between 40 and 800 ms long.
Troubleshooting
If an internal memory error occurs, the power
LED will flash alternating red/green. If this
occurs, either cycle the power or reteach the
sensor.
Sensing range/Excess gain
The range at which an object can be detected
will depend on the surface of the target. The
specified range is valid for a specific test card.
The table gives estimates for the required
excess gain factor to detect various surfaces in
clean laboratory conditions.
Shiny surfaces
Very shiny surfaces will reflect all the emitted
light away from the sensor if it is not positioned
exactly perpendicular to the surface. Sensors
with a diverging beam, like the SME312W, will
also detect skewed or fluttering surfaces.
Background
For an application to work reliably, objects or
surfaces that reflect an equal amount of light as
the target to be detected should be at least 4
times as far away from the sensor as the actual
target.
Status Action Result
RUN mode (green LED ON) Push and hold button for > 2 s Green LED goes OFF, yellow LED comes ON, red LED flashes (see AID™)
Teach condition 1 Present ON condition; click once Green LED stays OFF, yellow LED goes OFF, red LED flashes (see AID™)
Teach condition 2 Present OFF condition; click once
If contrast is acceptable: green LED comes ON, sensor goes into RUN mode
If contrast is too low: yellow LED comes ON, sensor goes back to teach condition 1

光沢面
Most light is lost to specular reflection with shiny surface at an angle to sensor lens.
Die Lichtintensität wird aufgrund spiegelnder Reflexion durch glänzende Oberflächen,
die winklig zur Sensorlinse ausgerichtet sind, deutlich gemindert.
La plupart de la lumière est réflechie en dehors du champs de vue du détecteur du à
l’angle de la surface brillante.
光沢面で斜角を持たせて反射させた場合、光線の大半は鏡面反射してしまいます。
