MOUNTING
WIRING
INSTALLATION STEPS
Use the adhesive mounting template to
position the sensor correctly. The grey
area indicates the measurement range.
Drill 2 holes as indicated on the
mounting template. Make a hole for
the cable.
Pass the cable through the cable hole. Position the sensor and fasten
the screws firmly.
*
Use M4 screws

SAFETY
Do not look into the laser
emitter directly for long time. The warranty is void if
unauthorized repairs are
made or attempted by
unauthorized personnel.
Only trained and qualified
personnel may install and
adjust the sensor.
INSTALLATION AND MAINTENANCE
Avoid extreme
vibrations.
Do not cover
the front screens.
Avoid moving objects
and light sources in
the measurement
field.
Avoid condensation.
Avoid the presence
of smoke and fog
in the measurement
field.
Avoid exposure to
sudden and extreme
temperature changes.
Keep the sensor
permanently powered
in environments where
the temperature can
descend below -15 °C.
Wipe the front
screens regularly
with a clean and
damp cloth.
Do not use aggressive
products to clean
the front screens.
Avoid direct exposure
to high pressure
cleaning.
CAUTION!
Use of controls, adjustments or performance of procedures other than those specified herein
may result in hazardous radiation exposure.
The device contains IR and visible laser diodes.
IR laser: wavelength 905nm; max. output pulse power 75W
(Class 1 according to IEC 60825-1)

TROUBLESHOOTING
No LED
The orange LED
is on.
There is no power.
The power supply voltage
is exceeding the acceptable
limits.
The sensor exceeds its
temperature limits.
Internal error
Check cable and connections.
Check the power supply voltage.
Verify the outside temperature where the sensor
is installed. Eventually protect the sensor from
sunlight using a cover.
Wait a few seconds.
If the LED remains ON, reset the power supply.
If the LED turns on again, replace the sensor.
Enable LED by command.
The orange LED
flashes 3 times. EEPROM error Open the cover. Keep pushing RESET button for more
than 2 seconds. Repower the sensor.
NOTES
LED is disabled.
