  • Page 34: Alignment Procedure

    SG4 EXTENDED INSTRUCTION MANUAL 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 35 ALIGNMENT PROCEDURE 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.

    FUNCTIONS 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 42: Fig. 32 – Restart Timings (Manual)

    SG4 EXTENDED INSTRUCTION MANUAL 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 RESTART push-button must be kept pressed for at least 500 msec.

  • Page 48: Muting

    SG4 EXTENDED 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 49: Muting Function Disable

    FUNCTIONS 7.7.1 Muting function disable During SG4 EXTENDED 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 50: Fig. 41 – T Muting Timings

    SG4 EXTENDED 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 53: Muting Timeout

    FUNCTIONS 7.7.5 Muting timeout Muting timeout is a time that defines the maximum duration of muting function; after the timeout the muting ends. This time can be set from the user in both BCM and ACM mode. In BCM mode 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.

  • Page 54: Muting Filter

    SG4 EXTENDED INSTRUCTION MANUAL 7.7.6 Muting Filter This function avoids undesired activations of the muting. The muting filter is a filter on muting inputs; low-high or high-low transitions of MUTING signals are considered valid only if maintained for a time (Tf) greater than 100ms. If this function is disabled the logical level of the muting sensors corresponds to the wire level.

  • Page 55: Partial Muting

    FUNCTIONS 7.7.7 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. In ACM Configuration the user can select a maximum of 5 muting zones, each defined with the following parameters: - Position: first beam of muting zone (starting from user display cap) - Dimension: number of beams of muting zone...

  • Page 56: Override

    SG4 EXTENDED 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 57: 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 59: Override Restart

    FUNCTIONS ACM Configuration: Override Timeout 7.8.3 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 60: Fig. 53 – Override Restart Timings (Auto)

    SG4 EXTENDED INSTRUCTION MANUAL AUTO OVERRIDE RESTART The OSSDs go in normal operation state after the RESTART signal goes low, and not after 500msec. A timeout of 5s on the high RESTART brings the ESPE in failure lockout. The outputs go high after a time that is the maximum value between the recovery time and the time of restart high (greater or equal to 500msec), so this time can be any value between 500ms and 5s.

  • Page 61: Fig. 54 – Override Restart Timings (Normal)

    FUNCTIONS NORMAL OVERRIDE RESTART The OSSDs go in normal operation state after the RESTART signal goes low, and not after 500msec. A timeout of 5s on the high RESTART brings the ESPE in failure lockout. The outputs go high after a time that is the maximum value between the recovery time and the time of restart high (greater or equal to 500msec), so this time can be any value between 500ms and 5s.

  • Page 62: Blanking

    SG4 EXTENDED INSTRUCTION MANUAL BLANKING Blanking is an auxiliary function of safety light curtains for which the introduction of an opaque object inside parts of the light curtain’s controlled area is allowed without stopping the normal functioning of the machine. Blanking is only possible in the presence of determined safety conditions and in accordance with a configurable operating logic.

  • Page 63: Fixed Blanking

    FUNCTIONS 7.9.1 Fixed Blanking Fixed Blanking allows a fixed portion of the controlled area (i.e. a fixed set of beams) to be occupied, while all the other beams operate normally. The blanking zone can be obtained through a Teach-in operation: the user has to keep pressed the 24VDC normally-open contact of Teach-in (pin 4 of M12-12 poles - RX) for at least 3 seconds while an object intercepts the area to be blanked.

  • Page 64: Fixed Blanking With Increased Tolerance

    SG4 EXTENDED INSTRUCTION MANUAL 7.9.2 Fixed Blanking with increased tolerance This is a fixed blanking with the tolerance only on one side of the blanking zone, so the user has to choose a “tolerance top” or a “tolerance bottom”. This function is useful for conveyors (that use fixed blanking) with goods moving on them (with a dimension within the tolerance).

  • Page 65: Reduced Resolution

    FUNCTIONS 7.9.5 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 normal 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.
