Controls

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.

Installation Modes

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.

Diagram shows two sensor units, labeled TX (Emitter) and RX (Receiver), facing each other across a 'Controlled Area' with 'Controlled Height' and 'Operating Distance (D)' indicated.

Mount the 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 (= operating distance x controlled height).
• In agroindustrial 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 DATALOGIC technical sales support department.
• The AREAscan™ light grids are NOT safety devices, and so MUST NOT be used in the safety control of the machines where installed.

Further considerations:

• Avoid installation near very intense and / or blinking light sources, in particular near to the receiver unit.
• The presence of strong electromagnetic disturbances can condition the correct functioning of the device; this condition has to be carefully evaluated and checked with the DATALOGIC technical sales support department.
• The presence of smoke, fog and suspended dust in the working environment can reduce the operating distance of the device.
• 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™ device (above, under 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.

Connections

Diagram shows electrical connections for ANALOGUE OUTPUT and SWITCHING OUTPUT. For the RECEIVER (RX) and EMITTER (TX) units, using M12 5-pole and 4-pole connectors respectively. Pin assignments (brown, white, blue, black, grey) for +24 Vdc, SYNC, Analogue output, Switching output, and Not used are detailed.

• RECEIVER (RX) M12 5-pole connector: 1 – brown: +24 Vdc, 2 – white: Analogue output, 3 – blue: 0 V, 4 – black: Switching output, 5 – grey: SYNC.
• EMITTER (TX) M12 4-pole connector: 1 – brown: +24 Vdc, 2 – white: Not used, 3 – blue: 0 V, 4 – black: SYNC.

• Shielded cables are not foreseen in the standard connection.
• Ground connection of the two units is not necessary.
• Use the same power supply for both units: for a correct functioning it's necessary that both units TX and RX have the same voltage reference 0V.

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 5 mm) and determine linear measurements with a ±3 mm error in best cases.

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 analogue output value (0-10 V) is proportional to the number of obscured beams (0V means that no beam is interrupted, 10V all beams interrupted).

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.

Diagram shows graphs illustrating the typical minimum resolution (R) in mm versus operating distance (D) in mm for various models (DS1-HD-SR-XXX-JV, DS1-LD-SR-XXX-JV, DS1-SD-SR-XXX-JV, DS1-LD-SR-XXX-PV, DS1-SD-HR-XXX-JV, DS1-LD-HR-XXX-JV).

EMISSION POWER REGULATION (only DS1-LD-SR-XXX-PV)

The emitter is equipped with a trimmer which lets the user change the emission power. The operating distance increases rotating the trimmer clockwise. The emission power reduction is useful to decrease passive reflections when the maximum operating distance is not required. Trimmer rotation is limited to 260°. Do not apply a torque greater than 35 Nmm.

To adjust: Rotate the trimmer clockwise to the limit (maximum emission), then align RX and TX at the required operating distance (LED OUT off); decrease emission power rotating the trimmer counterclockwise until the output switches (LED OUT off) or the limit is reached (minimum emission). In the first case, rotate the trimmer clockwise until the output switches again and LED OUT remains off.
