  • Page 14: How To Choose The Device

    GENERAL INFORMATION 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. 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.

  • Page 15: Height Of The Detection Zone

    HOW TO CHOOSE THE DEVICE Height of the detection zone The controlled height is the height protected by the safety light curtain. Figure 2 - Detection zone Referring to the figure above the protected height is reported in the table here below. CONTROLLED MODEL HEIGHT Hp (mm)

  • Page 16: Minimum Installation Distance

    GENERAL INFORMATION Minimum installation distance The safety device must be positioned at a specific safety distance (Figure 3). This distance must ensure that the dangerous area cannot be reached before the dan- gerous 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 17 HOW TO CHOOSE THE DEVICE 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 (Figure 4) the dis- tance between the dangerous area and the most distant optical beam must be equal to the value calculated using the following formula:...

  • Page 18: Typical Applications

    GENERAL INFORMATION TYPICAL APPLICATIONS Example 1: Operating point protection on drilling machines The operator positions the part and takes it back after machining. The operator must be protected against possible abrasions while working. Solution: SG 14mm safety light curtain is especially suitable for this kind of application, which requires the installation of the device directly on the machine.
  • Page 19 TYPICAL APPLICATIONS Example 3: Paper cutting machines These machines typically cut paper to a specific size for newspapers or special applica- tions. The operator must be protected against abrasion or cuts by cutter blades. Solution: SG 30mm safety light curtain is especially suitable for this kind of application, which require the installation of the device directly on the machine.

  • Page 50: Functions

    CHAPTER 7 FUNCTIONS This chapter deals with all the functions of the light curtain. 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 51 RESTART MODE Please refer to paragraph 8.4 EDM for RESTART input connection when used in combina- tion with EDM function on SG4-N models. SG4-P Restart Connection (Auto) SG4-N Restart Connection (Auto) 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 (nor- mal open push button) and after the object has been removed from the controlled area.
  • Page 52 FUNCTIONS Figure 3 - SG4-N Restart timings (manual) In Manual Restart the RESTART input (pin 3 of M12-12 poles or pin 1 of M12 8 poles - RX side) has to be connected to 24VDC through a normally- open contact for SG4-P models or a normally closed contact on SG4-N models.

  • Page 53: Test

  • Page 54: Reset

    FUNCTIONS 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 input (pin 3 of M12-8 poles - RX side) has to be kept pressed for at least 5 seconds in non-crit- ical failure state.
  • Page 55 Figure 8 - EDM connection with manual restart selected on SG4-N models The function controls the 24VDC normally-closed contact switching according to the changes of the OSSDs status. Figure 9 - EDM timings The EDM status is antivalent with OSSDs: the timing diagram explains the relationship between the cause (OSSDs) and the effect (EDM) with the maximum permissible delay.

  • Page 56: Edm Selection

    FUNCTIONS EDM disabled When EDM is disabled it's necessary to leave the EDM input floating for SG4-…-P mod- els. Please refer to 8.1 RESTART MODE for EMD/RESTART line connection on SG4-…-N models. Figure 10 - EDM disabled EDM SELECTION This function allows the user to select or exclude the monitoring of the external switch- ing devices.

  • Page 57: Range Reduction

    RANGE REDUCTION RANGE REDUCTION This function allows the user to select the maximum operating distance at which the curtains can be mounted. When Long Range is selected on RX, if TX is configured as Long Range, the maximum operating distance is 20m (30mm resolution) and 7m (14mm resolution); if TX is config- ured as Short Range the maximum operating distance is 12m (30mm resolution) and 4m (14mm resolution).

  • Page 60: Typical Muting Application And Safety Light Curtain Connection

    FUNCTIONS Typical Muting application and safety light curtain connection The figure shows a typical Muting application: a protection installed on a conveyor should allow the pack passing-by but not the worker. The ESPE temporarily suspends its safety function on a correct activation sequence of A1, B1, A2, B2 sensors.
  • Page 61 MUTING After this time if the user wants to enter in Muting has to deactivate the Muting input and start the sequence from the beginning. Figure 20 - T Muting timings The sensors named A1/A2 are connected to the same Muting input (MUTING1) and the sensors named B1/B2 are connected to MUTING2.
  • Page 62 FUNCTIONS 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. “T12”...

  • Page 69: Override Timeout

    OVERRIDE FOR SG4-P Override timeout BCM Mode In both modes 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. ACM mode Override timeout is the maximum duration of override.

  • Page 70: Override Restart

    FUNCTIONS Override restart This kind of selection can be achieved only if the light curtain is in Manual Restart; the user can select the type of Override Restart: Normal or Auto. The user has to connect the RESET/RESTART/ALIGN input (pin 3 of M12-12 poles - RX side) to a 24VDC normally-open contact.
  • Page 71 OVERRIDE FOR SG4-P Normal Override restart When override ends if the beams are free the ESPE goes to interlock state and a restart is required to achieve normal operation state. The OSSDs go in normal operation state after the RESTART signal goes low, and not after 500msec.

  • Page 72: Override For Sg4-N

    FUNCTIONS OVERRIDE FOR SG4-N Override function activation To start override, the OSSD outputs must be switched off and at least one beam must be interrupted. CAUTION • If the entire detection zone is free for more than 2 s, the override function is immediately deactivated.

  • Page 73: Override At Run Time

    OVERRIDE FOR SG4-N Override at run time • One or both muting inputs must be active. • Press and release the RESET button 3 times < 1 s. The OSSD outputs will be acti- vated for more than 2 s and 600 s max. •...

  • Page 74: Fixed Blanking

    FUNCTIONS To activate all blanking functions Blanking Operation can be selected either in BCM or in ACM. Figure 47 - BCM Configuration: Muting/Blanking Selection Figure 48 - ACM Configuration: Muting/Blanking Selection Blanking function can be realized in two different modes: fixed blanking and floating blanking.

  • Page 75: Fixed Blanking With Increased Tolerance

    OVERRIDE FOR SG4-N In Fixed Blanking the beams of the blanked zone have to remain intercepted, otherwise the light curtain goes in SAFE state. The Tolerance function can be activated by keeping pressed at startup the 24VDC nor- mally-open contact on Tolerance signal (pin 9 of M12-12 poles - RX). With Tolerance active the object can move 1 beam above or below the blanking zone.

  • Page 76: Floating Blanking With Total Surveillance

    FUNCTIONS Floating Blanking with total surveillance Floating Blanking with total surveillance allows the object to move freely inside the light curtain's controlled area. The blanked beams must be occupied and therefore the object has to be inside the controlled area of the light curtain to remain in normal operation state.

  • Page 77: Reduced Resolution

    OVERRIDE FOR SG4-N Reduced resolution Reduced Resolution is a particular kind of floating blanking in which more than one object can intercept each a defined number of beams with the ESPE remaining in nor- mal operation. The number that follows indicates how many adjacent beams can be intercepted by the object to allow the light curtain to remain in Normal Operation.

  • Page 78: Tolerance

    FUNCTIONS Tolerance There are 2 types of tolerance: position and dimension. Position Tolerance It indicates the number of beams in blanking zone that can be intercepted above and below the blanking zone without making the OSSDs switch off. In presence of wide vibrations, it is useful to use this function in order to avoid the changing of the OSSDs' status.
  • Page 79 OVERRIDE FOR SG4-N Figure 54 - Dimension tolerance Blanking in Basic Configuration Mode In basic configuration mode only a reduced set of possible blanking configuration is pos- sible. Figure 55 - BCM Configuration: Fixed Blanking 1 Fixed Blanking zone: only 1 zone can be configured as blanking zone. 2 Fixed Blanking zones: 2 zones can be configured as blanking zone.
  • Page 80 FUNCTIONS Blanking in Advanced Configuration Mode In ACM a maximum of 5 blanking zones (fixed + floating) can be configured (at least 1 beam of separation between zones is necessary). In ACM the number of beams can be chosen by the user. Reduced Resolution Figure 57 - ACM Configuration GUI calculates the maximum object size (in mm) that can intercept ESPE without caus-...
  • Page 81 OVERRIDE FOR SG4-N Fixed Blanking The panel on the right shows the settings of the active blanking zone (in the example here below the active blanking zone has a dimension of 3 beams and is 7 beams from the bottom of the light curtain; no tolerance is set).

  • Page 83: Cascade (Sg4-P Models)

    CASCADE (SG4-P MODELS) CASCADE (SG4-P MODELS) A dedicated Bus provides the connection between Master and Slave units. The same bus is used to connect SG4-DONGLE which links the light curtain to Ethernet. A proprietary transmission protocol for bus is used to communicate to slaves safety related information and status.

  • Page 84: Coding (Sg4-P Models)

    FUNCTIONS The connection among the light curtains needs a Cascade Cable that is available in three different lengths: • Cascade Cable 1 m (CS-F1-80-B-01) • Cascade Cable 0.5 m (CS-F1-80-B-005) • Cascade Cable 0.05 m (CS-F1-80-B-0005) The cascade cable must be connected between a Top side (without LEDs) and a Bottom Side (with LEDs) of two SG4-P Light Curtains.
  • Page 85 CODING (SG4-P MODELS) Code 1 or Code 2 When the user has to install two light curtains at a distance that is lower than the mini- mum distance allowed from homologous devices (and has to have the RXs on the same side), he has to configure the light curtains with different codes.
