  • Page 11: How To Choose The Device

    SG2 MUTING INSTRUCTION MANUAL 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. 1.3.1 Resolution The resolution of the device is the minimum dimension that an opaque object must have in order to obscure at least one of the beams that constitute the sensitive area.

  • Page 12: Controlled Height

    The controlled height is the height protected by the safety light curtain Fig. 2 – Controlled height The height controlled by the SG2 MUTING is the whole height of the light curtain. Referring to the figure above the protected height is reported in the table here below.

  • Page 13: Minimum Installation Distance

    SG2 MUTING INSTRUCTION MANUAL 1.3.3 Minimum installation distance The safety device must be positioned at a specific safety distance (Fig. 3). This distance must ensure that the dangerous area cannot be reached before the dangerous motion of the machine has been stopped by the ESPE.
  • Page 14 GENERAL INFORMATION where: S = Minimum safety distance in mm. t1 = Response time of the ESPE in seconds (see chapter 11) t2 = Machine stopping time in seconds. H = Beam height from ground; this height must always be less than 1,000 mm. Fig.

  • Page 32: Alignment Procedure

    ALIGNMENT PROCEDURE 5 ALIGNMENT PROCEDURE The alignment between the emitting and the receiving units is necessary to obtain the correct functioning of the light curtain. A good alignment prevents output’s 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 INSTRUCTION MANUAL 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.

  • Page 34: Function Setting

    FUNCTION SETTING 6 FUNCTION 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.

  • Page 37: Functions

    SG2 MUTING INSTRUCTION MANUAL 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 38 FUNCTIONS 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.

  • Page 39: Test

    SG2 MUTING INSTRUCTION MANUAL Restart Mode Auto Led 5 ON Red Manual Led 5 OFF 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.

  • Page 40: 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). activate RESET function 24VDC normally-open button connected RESET/RESTART/ALIGN input (pin 3 of M12-12 poles – RX side) has to be kept pressed for at least 5 seconds in non critical failure state.
  • Page 41 SG2 MUTING INSTRUCTION MANUAL The function controls the 24VDC normally-closed contact switching according to the changes of the OSSDs’ status. Fig. 34 – 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 42: Edm Selection

    FUNCTIONS EDM SELECTION This function lets the user to select or exclude the monitoring of the external switching devices. EDM Selection Enabled Led 4 ON Yellow Disabled Led 4 OFF To increase safety level, when EDM is set OFF, at start-up ESPE checks if EDM input is floating.

  • Page 43: Muting

    SG2 MUTING INSTRUCTION MANUAL 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.

  • Page 44: Muting Function Disable

    FUNCTIONS 7.7.1 Muting function disable During SG2 MUTING 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).
  • Page 45 SG2 MUTING INSTRUCTION MANUAL T muting In T type operations the device enters muting function if the input MUTING2 goes high within a fixed T12max after the rise of MUTING1 (or viceversa). The muting function ends as soon as the signal on MUTING1 or MUTING2 goes low. A further custom delay (Tdelay) may be set by the user in a 0-1000 ms range.
  • Page 46 FUNCTIONS Fig. 40 – T muting connection L muting 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”...

    FUNCTIONS Muting Timeout 10 min Led 7 ON Green infinite Led 7 OFF Note: Infinite is not 61496-1 compliant! 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.

  • Page 49: Override

    SG2 MUTING INSTRUCTION MANUAL 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.

  • Page 50: Override Mode

    FUNCTIONS 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.

  • Page 51: Override Timeout

    SG2 MUTING INSTRUCTION MANUAL Override Mode Level Led 8 ON Green Edge Led 8 OFF 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.
