INSTRUCTION MANUAL
CONTROLS
OUT LED (yellow)
The yellow LED indicates the output status.
READY LED (green)
During functioning, the green LED permanently ON
indicates a normal operating condition; fast blinking
indicates an output overload condition.
DELAY LED (orange)
The orange LED ON indicates the timing function
activation on the digital output.
MARK PUSH-BUTTON
The mark detection procedure is activated by pressing
MARK push-button.
BKGD PUSH-BUTTON
The background detection procedure is activated by
pressing BKGD push-button.
See the "SETTING" paragraph for setup procedure
indications.
INSTALLATION
The sensor can be positioned using threaded M5 holes with max. 6 mm
depth.
Do not apply excessive torque when adjusting (max 2.2 Nm).
operating distance is measured starting from the front surface of the
The
sensor optics.
The reading direction can be changed inverting the cap and lens.
Mark detection on a reflective surface is improved adjusting the beam
direction to 5° ... 20° from surface axis.

SETTING
DETECTION (MARK-BACKGROUND)
- Position mark in front of the sensor light spot and
press MARK push-button until the READY LED
(green) turns OFF.
The sensor detects the mark alternating the red,
green and blue emissions.
Avoid mark movements during this phase.
- Position the background in front of the sensor light
spot and press BKGD push-button; the sensor
detects the mark alternating the red, green and
blue emissions. Avoid background movements
during this phase.
The DARK/LIGHT operating mode is automatically
selected by the sensor.
Dark mark - light background = Dark mode.
Light mark - dark background = Light mode.
If the READY LED (green) is permanently ON, the
detection is successful.
If the LED blinks slowly, the detection has failed due
to insufficient contrast.
The sensor returns to the previous setting by pressing one of the two push-
buttons.
DELAY SETTING
The DELAY extends to 20ms the minimum duration of the active output
allowing the slower interfacing systems to detect shorter pulses.
The active delay is signalled by the corresponding orange LED ON.

Delay activation
Press MARK and BKGD push-buttons contemporaneously
for 2 sec. until the DELAY LED turns ON.
Delay deactivation
Press MARK and BKGD push-buttons contemporaneously
for 2 sec. until the DELAY LED turns OFF.
OUTPUT OVERLOAD
The digital output overload is signalled by the rapid blinking of the READY
LED.
The sensors are NOT safety devices, and so MUST NOT be used in the safety control of the machines
where installed.
