DATALOGIC DS1 Series Measuring Light Grid Instruction Manual

DATALOGIC DS1 Series Measuring Light Grid

Specifications

• Model : DS1 SERIES
• Receiver (RX) Controls Out LED: Yellow LED ON indicates the presence of an object in the controlled area.
• Receiver (RX) Power On LED: Green LED ON indicates optimal device functioning. Fast blinking indicates critical device alignment.
• Emitter (TX) Power On LED: Green LED ON indicates correct device functioning.

Installation Modes General information on device positioning:

• Align the receiver (RX) and emitter (TX) units, ensuring their distance is within the operating distance of the device.
• Place the sensitive sides of the units one in front of the other, with the connectors oriented on the same side.
• The critical alignment will be signalled by the fast blinking of the green receiver LED.

Mounting:

• Mount the receiver and emitter units on rigid supports that are not subject to strong vibrations.
• Use specific fixing brackets and/or the holes present on the device lids for mounting.

Precautions for choosing and installing the device:

• Choose the device based on the minimum object to detect and the maximum controlled area required.
• In agroindustrial applications, verify compatibility of light grid housing material with any chemical agents used in the production process with assistance from the DATALOGIC technicalsales support department.
• The AREAscanTM light grids are not safety devices and should not be used for safety control of the machines they are installed in.
• Avoid installation near intense and/or blinking light sources, especially near the receiver unit.
• Strong electromagnetic disturbances can affect correct functioning.

General Information on Object Detection and Measurement For correct object detection and/or measurement:

• The object must pass completely through the controlled area.
• It is suggested to test the correct detection before beginning the process.

Connections Receiver (RX): M12 5-pole connector

• Analogue Output: 2
• +24 Vdc: 1
• 0V: 3
• SYNC (RX)
• Switching Output

Emitter (TX): M12 4-pole connector

• +24 Vdc
• Not used
• 0V
• SYNC

Note: Shielded cables are not included in the standard connection. Ground connection of the two units is not necessary. Use the same power supply for both TX and RX units, ensuring they have the same voltage reference (0V) for correct functioning.

Functioning and Performances The beam interruption caused by an object passing through the controlled area results in the closing of the switching output and variation of the device’s analogue output signal. Small objects can be detected, reaching dimensions as small as 5 mm, with a 3 mm error in best cases for linear measurements. The switching output is always activated when at least one beam is obscured. The status variation is signalled by the yellow receiver LED turning on. FAQ

• Q: What do the different LED indicators on the receiver and emitter units signify? 
• A: The yellow LED on the receiver unit indicates the presence of an object in the controlled area. The green LED on the receiver and emitter units indicates the correct device functioning. The fast blinking of the green LED on the receiver unit indicates critical device alignment.
• Q : Can the AREAscan light grids be used as safety devices? 
• A : No, the AREAscan light grids are not safety devices and should not be used for safety control of the machines they are installed in.
• Q: How should I mount the receiver and emitter units? 
• A: Mount the units on rigid supports that are not subject to strong vibrations. Use specific fixing brackets and/or the holes -present on the device lids for mounting.

INSTALLATION MODES

General information on device positioning

• Align the two receivers (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 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 AREAscanTM light grids are NOT safety devices, and so MUST NOT be used in 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 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 AREAscanTM 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 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

• 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 correct functioning both units TX and RX must have the same voltage reference 0V

FUNCTIONING AND PERFORMANCES

The beam interruption due to the passage of an object inside the controlled area caused the closing of the switching output and the variation of the device’s 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, and 10V all beams are 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. The diagrams, given below, show the typical minimum resolution trend of each model, SR (standard resolution) and HR (high resolution), in according to the operating distance (D). For DS1-LD-SR-XXX-PV, the minimum resolution at a particular operating distance is to be intended with the trimmer calibrated near the commutation threshold for that distance.

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 it is useful to decrease passive reflections when the maximum operating distance it is not required. Trimmer rotation is limited to 260°. Do not apply a torque greater than 35 Nmm. 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 by 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.
