AS1 SERIES

OUT LED on receiver (RX)

The yellow LED ON indicates the presence of the object into controlled area.

POWER ON LED on receiver (RX)

The green LED ON indicates the optimal device functioning.
The fast blinking of the green LED indicates a critical device alignment.
Please refer to “DIAGNOSTICS” paragraph for other indications.

POWER ON LED on emitter (TX)

The green LED ON indicates the correct device functioning.
Please refer to “DIAGNOSTICS” paragraph for other indications.

General information on device positioning

• Align the two receiver (RX) and emitter (TX) units, verifying that their distance is inside
the device operating distance, in a parallel manner placing the sensitive sides one in
front of the other, with the connectors oriented on the same side. The critical alignment
of the unit will be signalled by the fast blinking of the green receiver LED.

• Mount the two receiver and emitter units on rigid supports which are not subject to
strong vibrations, using specific fixing brackets and /or the holes present on the device
lids.

Precautions to respect when choosing and installing the device

• Choose the device according to the minimum object to detect and the maximum
controlled area requested.

• In agro-industrial applications, the compatibility of light grid housing material and any
chemical agents used in the production process has to be verified with the assistance
of the DATASENSOR technical sales support department.

• The AREAscan
the safety control of the machines where installed.

Moreover the following points have to be considered:

- Avoid installation near very intense and / or blinking light sources, in particular near to
the receiver unit.

- The presence of strong electromagnetic disturbances can jeopardise the correct
functioning of the device. This condition has to be carefully evaluated and checked with
the DATASENSOR technical sales support department;

- The presence of smoke, fog and suspended dust in the working environment can
reduce the device’s operating distance.

- Strong and frequent temperature variations, with very low peak temperatures, can
generate a thin condensation layer on the optics surfaces, compromising the correct
functioning of the device.

- Reflecting surfaces near the luminous beam of the AREAscan
or lateral) can cause passive reflections able to compromise object detection inside the
controlled area.

- if different devices have to be installed in adjacent areas, the emitter of one unit must
not interfere with the receiver of the other unit.

General information relative to object detection and measurement

• For a correct object detection and / or measurement, the object has to pass completely
through the controlled area. Testing the correct detection before beginning the process
is suggested. The resolution is non uniform inside the entire controlled area. For
example the resolution in the AS1-HR model depends on the scanning program
chosen.

Ground connection of the two units is not
necessary. If desired, this connection can be
obtained replacing the screw provided in the
packaging with the one indicated in the
drawing, which blocks the lid of the connector
side of each unit.
The respect of the connection shown in the
drawing, is necessary if ground connection of
the entire system is requested.

FUNCTIONING AND PERFORMANCES

The beam interruption due to the passage of an object inside the controlled area causes
the closing of the switching output and the variation of the device analogue output signal.
Small objects can be detected (reaching dimensions of only 0.5 mm) and with a reduced
surface area.

In particular:
The switching output is always activated when at least one beam is obscured.

The status variation is signalled by the yellow receiver LED that turns on.
The device presents inputs (both on TX and Rx units) that consent the selection of the

resolution and response time.
Low response times correspond to worser resolutions and viceversa.

The device does not require calibration; periodical checks of the resolution and / or
measurement are however suggested.

The blinking of the green receiver LED (stability function) signals the critical alignment of
the units and / or the functioning outside or near the maximum operating distance. In
optimal conditions the LED remains on continuously.

The two units are synchronised via cable (SYNC wire).
Precarious connections or induced disturbances on the synchronism line can cause
device malfunctioning or a temporary blocking.

SCANNING PROGRAMS (only for AS1- HR)

The AS1-HR model presents inputs for the selection of the scanning program (SEL_RX ;
SEL_TX).
The selection is made connecting the input to +24Vdc.
The scanning program is activated only after input selection and device re-powering.
A different scanning program cannot be activated during device functioning.
According to the combination of the inputs selected, the response time or resolution can
be preferred, as described in the following table. The standard configuration (SEL_XX
floating inputs) corresponds to the lower resolution and highest response time .
