SG2 MUTING GENERAL VIEW Fig 1 - Safety light curtain LED description The microprocessor guarantees the check and the management of the beams that are sent and received through the units: the microprocessor – through some LEDs – informs the operator about the general conditions of the safety light curtain, both for settings and for diagnostics (see cfr.USER INTERFACE AND DIAGNOSTICS page 54).
SG2 MUTING 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 54).
SG2 MUTING 1.3 NEW FEATURES COMPARED TO SG2 BASE / SG2 EXTENDED With respect to SG2 BASE / SG2 EXTENDED series, safety light curtains of SG2 MUTING series have some new important features: Higher operating distance New profile compatible with SE accessories ...
SG2 MUTING 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.
SG2 MUTING 1.4.2 Height of the detection zone The controlled height is the height protected by the safety light curtain. Fig 3 - Detection Zone Controlled height Hp MODEL (mm) SG2-30-030-OO-W SG2-30-045-OO-W SG2-30-060-OO-W SG2-30-075-OO-W SG2-30-090-OO-W SG2-30-105-OO-W 1050 SG2-30-120-OO-W 1200 SG2-30-135-OO-W 1350 SG2-30-150-OO-W 1500...
SG2 MUTING 1.4.3 Minimum installation distance The safety device must be positioned at a specific safety distance (Fig 4 - page 13). 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 14
SG2 MUTING 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 5 - page 14) the distance between the dangerous area and the most distant optical beam must be equal to the value calculated using the following formula:...
Presses, punching machines, benders and cutters 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. The following pictures show some main applications.
SG2 MUTING 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 13 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 MUTING 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 9 - page 18 shows some examples of possible access to the machine from the top and the bottom sides.
SG2 MUTING 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 20
SG2 MUTING Diagram of Fig 14 - page 20 shows the minimum distance from the reflecting surface (Dsr), based on the operating distance: Fig 14 - Minimum distance from reflective surface The formula to get Dsr is the following: For ESPE Type 2: Dsr (m) = 0.6 for operating distance <...
SG2 MUTING 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.
Page 22
SG2 MUTING The figure provides two examples: Fig 17 - Recommended positioning for homologous devices If two light curtains have to be mounted near each other as reported in the first example of Fig 17 - page 22. 22/96...
SG2 MUTING 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 18 - Wrong light curtain TX-RX orientations 23/96...
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 MUTING 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 MUTING 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 60).
Page 27
SG2 MUTING The recommended mounting positions according to the light curtain length are shown in Fig 23 - page 27 and in the following table. Fig 23 - Light curtain dimensions MODEL L (mm) A (mm) B (mm) C (mm) SG2-30-030-OO-W 306.3 86.3...
SG2 MUTING 4 ELECTRICAL CONNECTIONS 4.1 PIN-OUT AND CONFIGURATION PIN CONNECTION All electrical connections to the emitting and receiving units are made through some particular cables; these cables are composed of a rectangular 18 pin connector on light curtain side and M12 male connector(s) on the other side. The Muting cable allows to have on the receiving unit one M12 12-pole connector and one M12 5-pole connector.
SG2 MUTING 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.
Page 31
SG2 MUTING 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 32 - OSSDs connection Fig 33 - Behaviour of OSSDs 31/96...
SG2 MUTING 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 33
SG2 MUTING In Alignment Mode ESPE is always in Safe State and the OSSDs are kept OFF. The state of alignment is estimated from RX unit by reading the received signal level of each beam compared on 4 factory established thresholds. First and last beams received level get some more weight. In alignment mode user interface informs the user about quality and level of alignment: Keep the receiver in a steady position and set the emitter until the yellow SYNC1 LED is OFF.
SG2 MUTING 6 FUNCTIONS SETTING ESPE operation functions and parameters configuration can be performed by means of push-buttons; this setting lets the user select among basic functions / basic parameters with the help of push buttons and led user interface (available on both RX and TX unit) Basic configuration mode: A user interface of 8 leds and 3 protected push buttons lets the user operate basic configuration.
SG2 MUTING 6.1 RESET TO FACTORY CONFIGURATION User can also reset ESPE at factory configuration settings with the following push button action: Press and keep pressed CONFIRM button for at least 9 sec. (but less than 30 sec. otherwise the light curtin goes in lockout failure) ...
SG2 MUTING 6.2 FUNCTION LIST The functions that can be chosen in SG2 MUTING are listed in the following tables. The default configuration is indicated in bold characters Fig 38 - RX Function list Fig 39 - Partial Muting selection Fig 40 - TX Function list 36/96...
SG2 MUTING 7 FUNCTIONS This chapter deals with all the functions of the light curtain. 7.1 RESTART MODE An opaque object detected by the beams causes the switching of the OSSD outputs (i.e. the opening of the safety contacts - SAFE condition). The restart mode allows the user to define how the light curtain returns in a Normal Operation condition.
Page 38
SG2 MUTING Manual Restart: after the ESPE has detected an opaque object in the controlled area, the light curtain begins its normal functioning only by pressing the Restart button (normal open push button) and after the object has been removed from the controlled area. The OSSDs go in normal operation state after the RESTART signal goes low, and not after 500msec.
SG2 MUTING 7.2 TEST The TEST function can be activated by pressing the 24VDC normally-open push-button connected to TX unit TEST input (pin 2 of M12-5 poles) for at least 0.5 seconds. The TEST disables the emission stage, so the RX side sees interrupted all beams and the OSSD goes low within response time.
SG2 MUTING 7.3 RESET When ESPE locks into failure state user can go back to Normal Operation with a power cycle or using the activation of RESET function (non critical failures only). To activate RESET function the 24VDC normally-open button connected to RESET/RESTART/ALIGN input (pin 3 of M12-12 poles –...
SG2 MUTING 7.4 EDM The External Device Monitoring (EDM) function controls external devices by verifying the OSSDs status. EDM enabled: When EDM is enabled in PNP configuration it’s necessary to connect EDM input (pin 6 of M12-12 poles - RX) to a 24 VDC normally-closed contact of the device to be monitored.
SG2 MUTING EDM disabled: When EDM is disabled it’s necessary to leave the EDM input floating. Fig 50 - EDM connection (PNP configuration) 7.5 EDM SELECTION This function lets the user to select or exclude the monitoring of the external switching devices. Fig 51 - EDM Selection To increase safety level, when EDM is set OFF, at start-up ESPE checks if EDM input is floating.
SG2 MUTING 7.6 REDUCTION RANGE This function allows the user to select the maximum operating distance at which the curtains can be mounted. If TX is configured as Long Range the maximum operating distance is 20m; if TX is configured as Short Range the maximum operating distance is 12m.
SG2 MUTING 7.7 MUTING Muting function allows automatic deactivation of the safety function on the whole or part of protected height in order to carry out definite cyclical operations without blocking machine work. As the pertaining safety requirements demand, ESPE is equipped with two Muting activation inputs, MUTING1 and MUTING2.
SG2 MUTING 7.7.1 Muting function disable During light curtain operations Muting function can be dynamically disabled or enabled: when disabled no valid Muting request will be accepted at the MUTINGX inputs and safety function will always be on. The user can disable the Muting function at runtime by setting a high level on the signal MUTING DISABLE (pin 7 of the M12-12 poles connector).
SG2 MUTING 7.7.4 Muting direction The ESPE can be used with both bidirectional (T type, four sensors) and monodirectional (L type, two sensors) Muting. Bidirectional Muting can be used in those applications in which the packs can move in both directions and monodirectional Muting can be used in those applications in which the packs move in one direction only.
Page 47
SG2 MUTING Fig 59 - Muting T connection Muting L In L type operation the device enters Muting function if the inputs go high in a particular order: MUTING1 has to activate first, then MUTING2 can activate; if MUTING2 activates before MUTING1, the device doesn’t enter the Muting function.
Page 48
SG2 MUTING The sensor named A is the farthest from the light curtain, so its beam is intercepted first. Making reference to the next figure, since the pack goes from right to left only, B sensor can’t be intercepted first; if this happens the device doesn’t enter Muting function.
SG2 MUTING 7.7.5 Muting timeout Muting timeout is a time that defines the maximum duration of Muting function; after the timeout the Muting ends. The user can select a timeout of 10 minutes or infinite; “infinite” means that muting timeout could never end: if the conditions of muting persist, the muting function still continues to exist.
SG2 MUTING 7.7.6 Partial Muting It’s possible to configure the type of muting: total or partial. Partial muting can be useful in those applications in which the user wants to limit the muting function effects to selected zones only. Hereafter the table that resumes the configuration in case of partial muting is presented. Fig 65 - Partial Muting Selection 50/96...
SG2 MUTING 7.8 OVERRIDE Override function allows the user to force safety function deactivation whenever it’s necessary to restart the machine despite one or more ESPE beams are intercepted. The aim is clearing protected area of any working materials blocked ahead of ESPE because of (i.e.) a cycle anomaly.
SG2 MUTING 7.8.1 Override mode It’s possible to configure the trigger of override inputs: Level or Edge. As explained in diagrams below two types of override trigger sequence are accepted on external inputs: LEVEL TRIGGER: Override engaged until both contacts are closed AND at least one Muting sensor is intercepted. OVERRIDE STATUS: status is an output signal that informs the user if the override inputs are active with override conditions present.
SG2 MUTING 7.8.2 Override timeout Override status timeout is 120s: if Override conditions remain active and both Override contacts remain closed (this condition only in Level Trigger Mode) more than 120s, the Override goes low in any case after a maximum of 120s. Fig 71 - Override timeout timings 53/96...
SG2 MUTING 8 USER INTERFACE AND DIAGNOSTICS 8.1 USER INTERFACE In the left side of user control panel (on both units of light curtains) an 8 LEDs user interface helps customer to control and check the state of the light curtain, for alignment mode, normal operation and for troubleshooting activity.
