SG2 BASE 1 GENERAL INFORMATION 1.1 GENERAL DESCRIPTION The safety light curtains are optoelectronic multibeam devices that are used to protect working areas that, in presence of machines, robots, and automatic systems in general, can become dangerous for operators that can get in touch, even accidentally, with moving parts.
As the required knowledge may not be completely included in this manual, we suggest the customer to contact Datalogic Technical Service for any necessary information relative to the functioning of the light curtains and the safety rules that regulate the correct installation (cfr. USER INTERFACE AND DIAGNOSTICS page 38).
SG2 BASE 1.3 NEW FEATURES COMPARED TO SF2 SERIES The SF2 safety light curtains, compared to the SG series, present the following new features: Increased operating distance Range enlargement with 150 to 1800 mm controlled heights Reduced response times ...
SG2 BASE 1.4 HOW TO CHOOSE THE DEVICE There are at least three different main characteristics that should be considered when choosing a safety light curtain, after having evaluated the risk assessment. 1.4.1 Detection capability The detection capability (or resolution) of the device is the minimum diameter that an opaque object must have in order to obscure at least one of the beams that constitute the detection zone and to actuate the sensing device.
Height of the detection zone The controlled height is the height protected by the safety light curtain. Fig 2 - Detection Zone Controlled height Model 30mm Model 50mm Model 90mm Hp (mm) SG2-30-015-OO-X SG2-30-030-OO-X SG2-50-030-OO-X SG2-90-030-OO-X SG2-30-045-OO-X SG2-50-045-OO-X SG2-90-045-OO-X SG2-30-060-OO-X...
SG2 BASE 1.4.3 Minimum installation distance The safety device must be positioned at a specific safety distance (Fig 3 - page 12). This distance must ensure that the dangerous area cannot be reached before the dangerous motion of the machine has been stopped by the Safety Control System. The safety distance depends on 4 factors, according to the EN ISO 13855 Standard: ...
Page 13
SG2 BASE When devices with > 40 mm resolution are used, the height of the top beam has to be ≥ 900 mm (H2) from machine supporting base while the height of the bottom beam has to be ≤ 300 mm (H1). If the safety light curtain must be mounted in a horizontal position (Fig 4 - page 13) the distance between the dangerous area and the most distant optical beam must be equal to the value calculated using the following formula:...
Page 14
SG2 BASE Practical examples Let's suppose to have a light curtain with height = 600 mm To calculate the distance of the device from the ESPE, in a vertical position, the following formula is used: S = K*T + C where: = Minimum safety distance in mm.
Automatic and semiautomatic assembly lines; Automatic warehouses. In food industry applications, DATALOGIC Technical Service has to verify the compatibility of the material of the safety light curtain housing with any chemical agents used in the production process. Example 1: Hand protection on moulding machine In order to protect the light curtain against dust and humidity, the IP69K protective enclosure is used.
Page 16
SG2 BASE Example 2: Cooling and air conditioning systems Cooling and air conditioning systems, as well as automotive equipment and components, are checked inside a machine to detect possible leaks using a helium mass spectrometer. The point where these parts are positioned inside the measuring chamber, requires a Type 2 protection ensuring space reduction and safe access to the protected area.
SG2 BASE 1.6 SAFETY INFORMATION For a correct and safe use of the safety light curtains, the following points must be observed: The stopping system of the machine must be electrically controlled. This control system must be able to stop the dangerous movement of the machine within the total machine stopping time T as per paragraph Minimum installation distance page 12 and during all working cycle phases.
The presence of intense electromagnetic disturbances could affect device’s correct operation. This condition shall be carefully assessed with the advice of DATALOGIC Technical Service. The operating distance of the device can be reduced in presence of smog, fog or airborne dust.
SG2 BASE 2.2 GENERAL INFORMATION ON DEVICE POSITIONING The safety light curtain should be carefully positioned in order to provide the necessary protection. Access to the dangerous area must only be possible by passing through the protecting safety light beams. Fig 8 - page 19 shows some examples of possible access to the machine from the top and the bottom sides.
SG2 BASE 2.2.1 Minimum distance from reflecting surfaces Reflecting surfaces placed near the light beams of the safety device (over, under or laterally) can cause passive reflections. These reflections can affect the recognition of an object inside the controlled area. Moreover, if the RX receiver detects a secondary beam (reflected by the side-reflecting surface) the object might not be detected, even if the object interrupts the main beam.
Page 21
SG2 BASE Diagram of shows the minimum distance from the reflecting surface (Dsr), based on the operating distance: Fig 13 - Minimum distance from reflective surface The formula to get Dsr is the following: For ESPE Type 2: Dsr (m) = 0.27 for operating distance <...
SG2 BASE 2.2.2 Distance between homologous devices The following graphic shows the distance from the interfering devices (Ddo) according to the operating distance (Ddo) of the couple ( TXA – RXA ). If different safety devices have to be installed in adjacent areas, the emitter of one device must not interfere dangerously with the receiver of the other device.

SG2 BASE 2.2.3 Emitter and Receiver Orientation The two units shall be assembled parallel each other, with the beams arranged at right angles with the emission and receiving surface, and with the connectors pointing to the same direction. The configurations shown in the figure must be avoided: Fig 16 - Wrong light curtain TX-RX orientations 24/68...
Even very small displacements of the mirror is enough to lose alignment. The use of DATALOGIC laser pointer accessory is recommended under these conditions. The minimum safety distance (S) must be respected for each single section of the beams.
SG2 BASE 2.2.5 Controls after first installation The control operations to carry-out after the first installation and before machine start-up are listed hereinafter. The controls must be carried-out by qualified personnel, either directly or under the strict supervision of the person in charge of machinery Safety.
SG2 BASE 3 MECHANICAL MOUNTING The emitting (TX) and receiving (RX) units must be installed with the relevant sensitive surfaces facing each other. The connectors must be positioned on the same side and the distance must be included within the operating range of the model used (see cfr.TECHNICAL DATA page 43).
Page 28
SG2 BASE Anti-vibration shock absorbers together with fixing brackets are recommended in applications with particularly strong vibrations to reduce the impact of the vibrations. Fig 21 - Fixing brackets Fig 21 - page 28 and table below show the recommended mounting positions according to the safety light curtain length.
SG2 BASE 4 ELECTRICAL CONNECTIONS 4.1 PIN-OUT AND CONFIGURATION PIN CONNECTION All electrical connections to the emitting and receiving units are made through a male M12 connector, located on the lower part of the two units. For receiver a M12 5-poles connector is used, while for emitter a M12 4-poles connector is used. RECEIVER (RX): Fig 23 - Receiver brown...
SG2 BASE 4.2 NOTES ON CONNECTIONS For the correct operation of the safety light curtains, the following precautions regarding the electrical connections have to be respected: Do not place connection cables in contact with or near high-voltage cables and/or cable undergoing high current variations (e.g.

SG2 BASE Connect both OSSDs to the device to control. Failure to connect an OSSD to the activating device jeopardizes the system safety degree that the light curtain has to control. Fig 26 - OSSDs connection 31/68...
SG2 BASE 4.3 EARTH CONNECTION Safety light curtain units are preset for easy ground connection. A special compartment, positioned onto caps and marked with the special symbol shown in Fig 27 - page 32, allows connection with ground cable by means of an additional screw coming with the equipment.
SG2 BASE 5 ALIGNMENT PROCEDURE The alignment between the emitting and the receiving units is necessary to obtain the correct operation of the light curtain. A good alignment prevents outputs instability caused by dust or vibrations. The alignment is perfect if the optical axes of the first and the last emitting unit's beams coincide with the optical axes of the corresponding elements of the receiving unit.
Page 34
SG2 BASE The standard installation described hereinafter is the one shown in Fig 29 - page 33, i.e. with the bar assembled with the connectors pointing down. Two yellow LEDs ( LAST, SYNC), on receiver, facilitates the alignment procedure. During standard operation, the LEDs indicate the safety light curtain status, as shown in the table. FUNCTIONING STATUS Normal Status Stop Status...
SG2 BASE 5.1 CORRECT ALIGNMENT PROCEDURE The light curtain alignment can be effected only after having completed the mechanical installation and the electrical connections as described above. Compare alignment results with those given in the following table: Check the green LED ( ) and the yellow LED ( ) on the TX unit.
SG2 BASE 6 FUNCTIONS SETTING 6.1 RESET MODE The interruption of a beam due to an opaque object causes the opening of OSSD outputs and the stop of the safety light curtain SAFE (BREAK) condition. Carefully assess risk conditions and reset modes. In applications protecting access to dangerous areas, the automatic reset mode is potentially unsafe if it allows the operator to pass completely beyond the sensitive area (see Fig 11 - page 19).
SG2 BASE 7 FUNCTIONS This chapter deals with all the functions of the light curtain. 7.1 TEST The TEST function can be activated by keeping a normally open external contact (TEST push-button), open for at least 0.5 seconds. The TEST signal is active high. Fig 30 - Test timings 7.2 RESET The RX light curtain has a RESET function which is activated after an internal error.
SG2 BASE 8 USER INTERFACE AND DIAGNOSTICS 8.1 USER INTERFACE The operator can visualise the operating condition of the light curtains through the four LEDs positioned on the receiver unit and two LEDs on the emitter unit. Fig 32 - page 38 shows all signalling LEDs modes: OFF, ON and BLINKING. Fig 32 - Signalling LEDs 38/68...
