SG4 EXTENDED

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 chapter 6 and 8).

1 GENERAL INFORMATION

1.1 GENERAL DESCRIPTION

1.1.1 General Description of the safety light curtains

The safety light curtains of the SG4 series 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.
The light curtains of the SG4 series are Type 4 intrinsic safety systems used as accident­prevention protection devices and are manufactured in accordance with the international
Standards in force for safety, in particular:

EN 61496-1/AC: 2010 Safety of machinery: electrosensitive protective equipment.

Part 1: General prescriptions and tests.

IEC 61496-2: 2006 Safety of machinery: electrosensitive protective equipment -

Particular requirements for equipment using active optoelectronic
protective devices.

EN ISO 13849-1: 2008 (Cat.4, PL e) Safety of machinery. Safety-related parts of control

systems.

The device, consisting of one emitter and one receiver housed inside strong aluminium
profiles, generates infrared beams that detect any opaque object positioned within the light
curtain detection field. The emitter and the receiver are equipped with the command and
control functions. The connections are made through a M12 connector located in the lower
side of the profile. The synchronisation between the emitter and the receiver takes place

optically, i.e. no electrical connection between the two units is required. 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 (see chapter 8 “Diagnostic”).

SG4 EXTENDED INSTRUCTION MANUAL

1

The device consists in 2 units that, according to the model, are composed by one or several
emitting and receiving modules. The receiver is the main controller for all functions. It
monitors all safety actions in case of failure and performs general functions as well.

During installation, an user interface facilitates the alignment of both units (see chapter 5

“Alignment procedure”).

As soon as an object, a limb or the operator’s body accidentally interrupts one or some of the
infrared beams sent by the emitter, the receiver immediately opens the OSSD outputs and
blocks the MPCE machine (if correctly connected to the OSSD).

Some parts or sections of this manual containing important information for the user or
installing operator are preceded by a note:

The information provided in the paragraphs following this symbol is
very important for safety and may prevent accidents.
Always read this information accurately and carefully follow the advice
to the letter.

GUI

The paragraphs containing descriptions reported on the GUI too are
written with this character.

This manual contains all the information necessary for the selection and operation of the
safety devices.
However, specialised knowledge not included in this technical description is required for the
planning and implementation of a safety light curtain on a power-driven machine.
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 SG light curtains and the safety rules that regulate the correct installation
(see chapter 9).

1.3 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.
The resolution strictly depends on the part of the body to be protected.

R =14mm finger protection

Type 4

R = 30 mm hand protection

Type 4

As shown in Fig. 1, the resolution only depends on the geometrical characteristics of the
lenses, diameter and distance between centres, and is independent of any environmental
and operating conditions of the safety light curtain.

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.
The safety distance depends on 4 factors, according to the EN ISO 13855 Standard (which
replaces EN999):

 Response time of the ESPE (the time between the effective beam interruption and the

opening of the OSSD contacts)

 Machine stopping time (the time between the effective opening of the contacts of the

ESPE and the real stop of the dangerous motion of the machine)

 ESPE resolution
 Approaching speed of the object to be detected

Fig. 3 – Minimum installation distance (vertical)

The following formula is used for the calculation of the safety distance:

S = K (t1 + t2) + C

where:

S = Minimum safety distance in mm
K = Speed of the object, limb or body approaching the dangerous area in mm/sec
t1 = Response time of the ESPE in seconds (see chapter 11)
t2 = Machine stopping time in seconds
d = Resolution of the system
C = Additional distance based on the possibility to insert the body or one of body parts inside the
dangerous area before the protective device trips.

C = 8 (d -14) for devices with resolution ≤ 40 mm
C = 850 mm for devices with resolution > 40 mm

NOTE: K value is:
2000 mm/s if the calculated value of S is ≤ 500 mm
1600 mm/s if the calculated value of S is > 500 mm

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), the distance
between the dangerous area and the most distant optical beam must be equal to the value
calculated using the following formula:

S = 1600 mm/s (t1 + t2) + 1200 – 0.4 H

GENERAL INFORMATION

7

1

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. 4 – Minimum installation distance (horizontal)

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:

T = t1 + t2
t

1

= ESPE response time + SE-SR2 relay release time (max 80 ms)

t

2

= Machine total stopping time.
C = 8 * (d – 14) for devices with resolution <= 40 mm
D = resolution

In all cases, if K = 2000mm/sec then S > 500 mm. Distance will have then to be recalculated
using K = 1600 mm/sec.

WARNING: the reference standard is EN ISO 13855 (replaces EN

999) “Safety of machinery - Positioning of safeguards with respect
to the approach speeds of parts of the human body”.
The following information is to be considered as indicative and
concise. For correct safety distance please refer to complete
standard EN ISO 13855.

1.4 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: SG4 EXTENDED 14 mm safety light

curtain is especially suitable for this kind of
application, which requires the installation of the
device directly on the machine.

Benefits: Highly reduced profile size guarantees

installation flexibility for machine dimensions.

Example 2: Bending presses

The safety device must protect the
operator from being squashed between the
top and bottom tool or the machined part
during the fast approach phase.

Solution: If only one beam of the SG4

EXTENDED safety light curtain is darkened
while the press is moving down, the mobile
tool bar will stop.

Benefits: The safety light curtain can be

used in most bending operations thanks to its easy installation and compact dimensions. As
well as offering excellent reliability, SG4 EXTENDED ensures increased plant productivity as
it reduces the dead times necessary for machine accessing, adjustment and maintenance.

Example 3: Paper cutting machines

These machines typically cut paper to a specific size for newspapers or special applications.
The operator must be protected against abrasion or cuts by cutter blades.

Solution: SG4 EXTENDED safety light

curtain is especially suitable for this kind
of application, which require the
installation of the device directly on the
machine.

Benefits: Highly reduced profile and the

two side slots ensure installation
flexibility for machine dimensions.

GENERAL INFORMATION

Example 4: Milling machines

A milling machine is a machine tool used for
the shaping of metals and other solid
materials. Operator hands and body must be
protected from being dragged, entangled or
cut by the tool / spindle.

Solution: SG4 EXTENDED series safety

light curtain is the best solution considering
the required safety levels and application
type. When even just one of the light curtain
beams is interrupted, the machine is immediately stopped.

Benefits: Highly reduced profile size guarantees installation flexibility for machine

dimensions.

1.5 SAFETY INFORMATIONS

For a correct and safe use of the safety light curtains of the SG4
series, 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 reported in par. 1.3.3 and during all
working cycle phases

 Mounting and connection of the safety light curtain must be carried out by qualified

personnel only, according to the indications included in the special sections (see
chapters 2, 3, 4, 5) and in the applicable standards

 The safety light curtain must be securely placed in a particular position so that access

to the dangerous zone is not possible without the interruption of the beams (see
chapters 2, 3)

 The personnel operating in the dangerous area must be well trained and must have

adequate knowledge of all the operating procedures of the safety light curtain

 The TEST button must be located outside the protected area because the operator

must check the protected area during all Test and Reset operations

Please carefully read the instructions for the correct functioning before powering the light
curtain.

2 INSTALLATION

2.1 PRECAUTIONS TO BE OBSERVED FOR THE CHOICE AND

INSTALLATION

Make sure that the protection level assured by the SG4 device
(Type 4) is compatible with the real danger level of the machine
to be controlled, according to EN ISO 13849-1 or EN 62061.

 Use only matched pair with same serial no.

 The outputs (OSSD) of the ESPE must be used as machine stopping devices and not

as command devices. The machine must have its own START command

 The dimension of the smallest object to be detected must be larger than the

resolution level of the device

 The ESPE must be installed in a room complying with the technical characteristics

indicated in chapter 11.

 Do not install anything close to strong and/or flashing light sources or close to similar

devices

 The presence of intense electromagnetic disturbances could affect device’s correct

operation. This condition shall be carefully assessed by seeking the advice of
Datalogic Technical Service

 The operating distance of the device can be reduced in presence of smog, fog or

airborne dust

 A sudden change in environment temperature, with very low minimum peaks, can

generate a small condensation layer on the lenses and so jeopardise functioning.

2.2 GENERAL INFORMATION ON DEVICE POSITIONING

The safety light curtain should be carefully positioned, in order to reach a very high protection
standard; access to the dangerous area must only be possible by passing through the
protecting safety light beams.

Fig. 5 shows some examples of possible access to the machine from
the top and the bottom sides. These situations may be very
dangerous and so the installation of the safety light curtain at a
sufficient height in order to completely cover the access to the
dangerous area (Fig. 6) becomes necessary.

Fig. 5 – Incorrect device positioning

Fig. 6 – Correct device positioning

Under standard operating conditions, machine starting must not be possible while operators
are inside the dangerous area.
When the installation of the safety light curtain very near to the dangerous area is not
possible, a second light curtain must be mounted in a horizontal position in order to prevent

any lateral access, as shown in Fig. 8.

If the operator is able to enter in the dangerous area, an additional
mechanical protection must be mounted to prevent the access.

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.

The minimum distance depends on:

 operating distance between emitter (TX) and receiver (RX);
 real aperture angle of ESPE (EAA); especially:

for ESPE type 4 EAA = 5° ( = ± 2,5°)

Diagram of Fig. 10 shows the minimum distance from the reflecting surface (Dsr), based on
the operating distance:

The formula to get Dsr is the following:
Dsr (m) = 0.15 for operative distances < 3 m
Dsr (m) = 0.5 x operating distance (m) x tg 2 for operative distances  3 m

2.2.2 Distance between homologous devices

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.
The TXB interfering device must be positioned outside a minimum Ddo distance from the
TXA – RXA emitter-receiver couple axis.

Fig. 11 – Distance between homologous devices

This minimum Ddo distance depends on:

 the operating distance between emitter (TXA) and receiver (RXA)
 the effective aperture angle of the ESPE (EAA)

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 Fig. 14 must be avoided:

Fig. 14 – Light curtains orientation

2.2.4 Use of deviating mirrors

The control of any dangerous area, with several but adjacent access sides, is possible using
only one safety device and well-positioned deviating mirrors.
Fig. 15 shows a possible solution to control three different access sides, using two mirrors
placed at 45° with respect to the beams.

Fig. 15 – Use of deviating mirrors

The operator must respect the following precautions when using the deviating mirrors:

 The alignment of the emitter and the receiver can be a very critical operation when

deviating mirrors are used. 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.

 The effective operating range decreases by about 15% by using only one deviating

mirror, the percentage further decreases by using 2 or more mirrors (for more details
refer to the technical specifications of the mirrors used).

The following table shows the operating distances relating to the number of mirrors used.

 Do not use more than three mirrors for each device.

 The presence of dust or dirt on the reflecting surface of the mirror causes a drastic

reduction in the range.

2.2.5 Checks 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.

Check that:

 ESPE remains in SAFE state intercepting the beams along the protected area using

the specific test piece (TP-14 or TP-30), following the Fig. 16 scheme.

 The response time at machine STOP, including the ESPE and machine response

times, must be included in the limits defined in the calculation of the safety distance
(refer to chapter 2)

 The safety distance between the dangerous parts and ESPE must comply with the

requirements indicated in chapter 2

 A person must not access or remain between ESPE and the dangerous parts of the

machine

 Access to the dangerous areas of the machine must not be possible from any

unprotected area

 ESPE must not be disturbed by external light sources, ensuring that it remains in

NORMAL OPERATION condition for at least 10-15 minutes and, placing the specific
test piece in the protected area, in the SAFE state for the same period

 Verify the correspondence of all the accessory functions, activating them in the

different operating conditions

MECHANICAL MOUNTING

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 chapter 11).

The two units must be positioned the most aligned and parallel possible.
The next step is the fine alignment, as shown in chapter 5.

Outfit angled fixing brackets kit, for units mounting, must be used as described below (Fig.

17).

Adjustable supports for adjusting unit inclinations around the axes are available on request
(see chapter 15).

To mount the angled fixing brackets kit, place the threaded pins metallic insert into the
dedicated side seat of the terminator cap side light curtain closing cap; slide the insert
towards the metallic drawn profile groove. Fix the bracket against the profile by tightening the
M5 hexagonal nuts. It’s possible to slide the bracket group along their dedicated rail and fix it
once again just working on the above mentioned nuts.

Fig. 17 – Fixed brackets mounting procedure

In case of applications with particularly strong vibrations, vibration dampers, together with
mounting brackets, are recommended to reduce the impact of the vibrations.

Fig. 18 – Anti-vibration dampers

The recommended mounting positions according to the light curtain length are shown in Fig.
19 and in the following table.

4 ELECTRICAL CONNECTIONS

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.
The Blanking cable allows to have on the receiving unit one M12 12-pole connector.
The emitting unit has one M12 5-pole connector (both in Muting and Blanking mode).
The cables have to be connected on the bottom side of the light curtains (leds and push
button side) by removing the white cap that is present.

Take care that the terminator cap (CVL-5196, see chapter 14) is connected on the top side of
the light curtains. If this connection misses, Master and Slave units go in critical
Communication failure.

N.B.: since the RX connections are different for M12 12-poles of muting cable and M12
12-poles of blanking cable, it’s important to use the correct cable for each
configuration (connector with two M12 with the muting configuration and connector
with one M12 with the blanking configuration)

4.1 NOTES ON CONNECTIONS

For the correct functioning of the SG4 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. motor power supplies, inverters, etc.);

 Do not connect in the same multi-pole cable the OSSD wires of different light

curtains;

 The TEST wire must be connected through a N.O. button to the supply voltage of the

ESPE.

The TEST button must be located in such a way that the operator can
check the protected area during any test.

The RESET/RESTART/ALIGN button must be located in such a way
that the operator can check the protected area during any reset
operation.

 The device is already equipped with internal overvoltage and overcurrent suppression

devices. The use of other external components is not recommended.

Example: connection to the safety relay.

Fig. 20 – Connection to safety relay

The figures show the connection between the safety light curtains and the safety relay of the
SE-SR2 series functioning in the Automatic Start mode (left side) and Manual Start with
monitoring (right side).

 Do not use varistors, RC circuits or LEDs in parallel at relay inputs or in series at OSSD

outputs.

 The OSSD1 and OSSD2 safety contacts cannot be connected in series or in parallel,

but they have to be used separately (Fig. 21).

 If one of these configurations is erroneously used, the device enters into the output

failure condition (see chapter 8).

 Connect both OSSDs to the device to control. Failure to connect an OSSD to the

activating device jeopardises the system safety degree that the light curtain has to
control.

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.
Since the light curtain has two beams for the synchronization, let’s call SYNC1 the sync
beam at the bottom, the first beam of the array, and SYNC2 the sync beam on the opposite
part of the light curtain, the last beam of the array.
The figure shows that the first beam is located at the bottom edge of the light curtain, near to
led display. The last beam is at the opposite near the terminator cap. These two beams are
the synchronization beams too.

Nth beam

Fig. 26 – Description of the beams

The Alignment function can be activated by simply keeping pressed the external normally
open push-button linked to RESET/RESTART/ALIGN input (pin 3 of M12-12 poles – RX
side) at start-up until the second led (red) begins to blink indicating the activation of the
Alignment function, as shown in the following timing diagram. When a good state of
alignment is reached a power OFF and a power ON operation carry back the ESPE in
normal operation.

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.
In alignment mode user interface informs the user about quality and level of alignment:

A. Keep the receiver in a steady position and set the emitter until the yellow SYNC1 LED

is OFF. This condition shows the effective alignment of the first synchronisation beam

B. Rotate the emitter, pivoting on the lower optics axis, until the yellow SYNC2 LED is

OFF

C. Delimit the area in which alignment is good and steady through some micro

adjustments - for the first and then for the second unit – in order to have the
maximum alignment LEVEL () and then place both units in the centre of this
area

D. Fix the two units firmly using brackets. Verify that the LEVEL on the RX unit is as high

as possible and beams are not interrupted, then verify that all LEVEL Led turn OFF if
even one single beam is interrupted. This verification shall be made with the special
cylindrical “Test Piece” having a size suitable to the resolution of the device used (see
par 2.2.5)

E. Switch-off and on the device in standard operating mode. The alignment level is

monitored also during the device normal operation with the same display (see par

8.1). Once the light curtain has been aligned and correctly fastened, the signal
display is useful both to check the alignment and show a change in the environmental
conditions (occurrence of dust, light disturbance and so on) via signal level monitoring

6 FUNCTION SETTING

ESPE operation functions and parameters configuration can be performed in two different
ways:

- Basic Configuration Mode (BCM):

Let 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)

- Advanced Configuration Mode (ACM):

Let the user select among advanced functions / advanced parameters with the help of a PC
Software GUI interface (available for RX only)

BASIC CONFIGURATION MODE

A user interface of 8 leds and 3 protected push buttons lets the user operate basic
configuration. Leds are the same used for user interface in normal operation.
The user must use the provided special tool (see chapter 14) to activate push buttons thus
accidental access to safety configuration is avoided.

Basic configuration steps:

In the right side of user control panel (on both units of the light curtain) a setting interface
composed by 3 push buttons is present; the purpose of the interface is to let the user set light
curtain locally and without use of PC graphic user interface.

Setting interface is composed by a CONFIRM push button used to enter in BCM and to
confirm the selected configuration, a SELECT push button used to roll by different functions
and an ENABLE push button to activate/deactivate the current function.

Here below the necessary steps for BCM configuration:

1. Keep CONFIRM button pressed to enter Basic Configuration Mode

2. A Test Pattern is shown on led interface; carefully check that ALL led are lit in sequence

from 2 to 8, then current configuration is shown

3. Choose function to set by SELECT button; selected led blinks

4. Configure selected function with ENABLE button (switch led on/off)

5. Repeat steps 3 and 4 until desired configuration is visualized

6. Keep CONFIRM button pressed to authorize the new configuration

If an Advanced Configuration is already set on ESPE (configuration by SG4-GUI PC User
Interface), a button pressure on Step 2 causes ESPE configuration failure lockout to prevent
unauthorized advanced configuration changes.

FUNCTION SETTING

29

6

ADVANCED CONFIGURATION MODE

SG Extended UI software (Graphic User Interface, GUI) for PC allows the user to set ESPE
advanced configuration. Many parameters are available to customize ESPE behaviour for
specific applications.
Since ESPE parameters can be safety critical and PC software cannot be guaranteed as a
safety component, a safe configuration procedure has to be followed.
Configuration procedure on UI can be done by authorized personnel only. Such personnel
must be sure that protected dangerous machine has no access during configuration
procedure.
There are 3 different kinds of operator that can use the GUI with 3 different levels of
authorizations.

System Integrator: has all the possible authorizations and can set every configuration on

the GUI

Maintainer: can upload the configurations (saved on the GUI) on the light curtain and use

the GUI for monitoring the system, but he can’t create new configurations

Machine Operator: uses the GUI only for monitoring the system

Depending on the kind of operator there are different passwords that protect some functions
of the GUI.

SG4 EXTENDED has two main operating modes: Blanking and Muting. Choosing between
Blanking and Muting changes the function setting associated to Leds 5 to 8.

N.B.: the default configuration is indicated in bold characters
N.B.: since the last 3 leds don’t change status by passing from a muting configuration

to a blanking configuration (and viceversa) and since these 3 leds have 3 different
meanings depending on the configuration, the user has to pay attention to the
configuration setting when decides to change configuration

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.
The restart of the ESPE (i.e. the closing of the OSSD safety contacts - SAFE condition) can
be carried-out in two different ways: Automatic or Manual Restart.

Automatic Restart: when an opaque object is detected, the ESPE enters in the SAFE

condition. Then, after the object has been removed from the controlled area, the ESPE
begins its normal functioning again.
The response time is the time between the object introduction in the protected area and the
OSSDs achieving the OFF state (SAFE); the recovery time is the time within OSSDs go in
the ON state (SAFE) after the object is removed.

These times are function of length. Please refer to the tables in chapter 12 for further details.

Fig. 30 – Restart timings (auto)

In Automatic Restart the RESET/RESTART/ALIGN input (pin 3 of M12-12 poles – RX side) has to be
left floating.

7

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. When the
RESTART push-button is released, the OSSD outputs switch to normal operation.

A timeout greater than 5s on the high RESTART brings the ESPE in failure lockout.

Fig. 32 – Restart timings (manual)

In Manual Restart the RESET/RESTART/ALIGN input (pin 3 of M12-12 poles – RX side) has to be
connected to a 24VDC normally-open contact.

Fig. 33 – Restart connection (manual)

WARNING: 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. In
this case, the manual reset or, for example, the manual reset of the SE-SR2
relay (see chapter 15) is necessary.

Here below the way to select the restart mode is explained, both through push-button and
the graphic user interface.

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. As shown in the timing diagram below, the OSSDs go
OFF (BREAK status) after 500msec (plus a cycle time) and after the response time of the
light curtain.

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 – RX side) has to be kept pressed for
at least 5 seconds in non critical failure state.
For all critical failures a power cycle is necessary.

When in failure state the light curtain can be reset with the procedure explained above except the case
of failure on microprocessor, for which a power cycle is necessary.

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.
The EDM function cannot be used in NPN configuration.

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.
The Muting sensors must be able to recognise the passing material (pallets, vehicles, …)
according to material’s length and speed. In case of different transport speeds in the Muting
area, it is necessary to consider their effect on the total Muting duration.

 The Muting function excludes the light curtain during functioning, maintaining active the

OSSDs’ outputs, according to particular operating requirements (Fig. 39).

Fig. 39 – Examples of muting application

 The safety light curtain is equipped with two inputs (MUTING1 and MUTING2) for the

activation of this function, according to the current Standards.

 This function is particularly suitable when an object, but not a person, has to pass through the

dangerous area, under certain conditions.

 It is important to remember that the Muting function represents a forced condition of the

system and therefore has to be used with the necessary precautions.

 If MUTING1 and MUTING2 inputs are activated by two Muting sensors or actuators, these

should be correctly connected and positioned in order to avoid undesired Muting or potentially
dangerous conditions for the operator.

 MUTING1 and MUTING2 can’t be activated simultaneously
 State of Muting is signalled by an external Muting Lamp (that can be connected to the light

curtains with the pin 10 of the M12-12 poles connector) and by some leds on the user
interface. When the Muting function is ON the LAMP and the leds begin to blink.

 During the installation take care to place the lamp in a position as visible as possible.
 If the external lamp is broken and/or not connected, the Muting request causes a SAFE

lockout condition and the corresponding failure is signalled.

 If both first and last beams are intercepted by the passing material the light curtain recovery

time may be longer. A material moving faster than 1 m/s could lead light curtain to switch in
OFF-state at the end of muting sequence.

Select carefully the configuration, as a wrong configuration can cause
the incorrect functioning of the Muting function and a reduction of the
safety level. For correct use of Muting, please refer to the relevant
reference standards.

The Muting sensors must be positioned in such a way that the
activation of the Muting function is not possible with the accidental
passing of a person. Particular attention must be paid to the use of the

one-way L-muting mode: the external muting sensors or the SG-L­ARMS muting arms must be positioned so as to allow the passage of
the material coming out of the dangerous area protected by the light
curtain.

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).

7.7.2 Muting signalling devices

In order to make use of Muting function, it is compulsory to connect a dedicated signalling
device (lamp); without it the light curtain goes in failure lock-out state.
Both incandescent and LED lamps are allowed. In case of use of LED lamp, take care to
connect it respecting the right polarity .
A Lamp TEST is executed cyclically when the lamp is lighted on in order to guarantee the
detection of lack of functionality. If a lamp break is detected, ESPE goes in Lamp Failure
Lock-Out state and shows the related message on the display (refer to chapter 11 for
informations about the lamp).

7.7.3 Typical muting application and safety light curtain connection

Fig. 40 – Typical Muting Application

The figure above 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.
These sensors can be optical, mechanical, proximity sensors … etc., with high output PNP
when the object is detected.

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.
In BCM the maximum activation delay between MUTING1 and MUTING2 (T12max) is 4 sec.

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. The maximum activation delay between MUTING1 and
MUTING2 (or viceversa) can be set by the user from a minimum of 1 sec to a maximum of
16 sec (T12max). After this time if the user wants to enter in muting has to deactivate the
muting input and start the sequence from the beginning.

Fig. 41 – 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. The sensors that end with “1” are on the
same side of the light curtain and are on the opposite side of the sensors that end with “2”.

“D” is the distance at which the sensors A1/A2 or B1/B2 have to be mounted; it depends on
the package length (L):

D < L

“d1” is the maximum distance between the muting sensors; it depends on the package speed
(V):

Fig. 42 – 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” is the activation delay between MUTING1 and MUTING2 that is selectable by the user
by means of ACM.
The muting function ends after a time that is a multiple of the activation delay between the
two sensors (this time is m * T12). The value of “m” (T12 multiplier) can be chosen by the
user. In BCM this value is 2 by default.
The maximum activation delay between MUTING1 and MUTING2 can be set by the user
from a minimum of 1 sec to a maximum of 16 sec. After this time if the user wants to enter in
muting has to deactivate the muting input and start the sequence from the beginning.

Muting L must be used exclusively for removing materials from the
dangerous area.

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.
“V” indicates a constant speed. As a consequence, “d1” is fixed according to the following
formula:

d1[cm] = V[m/s] * T12[s] * 100

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. This is not compliant with the 61496-1 rule and the user is warned about
it.

Fig. 45 – Muting timeout

The user can personalize the timeout from 10 minutes to 1080 minutes (that correspond to
18 hours) with steps of 1 minute; the user can even set infinite timeout. In this case there’s a
warning that alerts the user that this timeout is not IEC 61496-1 compliant.

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

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

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.

Override redundant inputs have to be connected to a 24VDC normally-open contact and to a
GND normally-open contact.
As the pertaining requirements request ESPE is equipped with two Override activation
inputs: OVERRIDE1 and OVERRIDE2 (respectively, pin 4 of the M12-12 poles connector
and pin 9 of the M12-12 poles connector – RX).

Fig. 48 – Override connection

Necessary condition for override request to be accepted is: ESPE in SAFE state and at least
one muting sensor intercepted.
When such condition is verified user interface visualizes “override attention status” with both
red OSSD led and alignment leds blinking.

OVERRIDE ATTENTION STATUS

Then, an override request is accepted only if signals at OVERRIDE X inputs follow the
timings shown hereafter.
Override function will automatically end when one of the following conditions is present:

 all the muting sensors are deactivated (in a T-muting configuration)
 all the muting sensors are deactivated AND no beams are intercepted (in a L-muting

configuration)

 the pre-determined time limit has expired
 the requirements for actuation aren’t met anymore (for example, one override input is

deactivated)

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.
OVERRIDE STATUS is an output signal that informs the user if the override inputs are active
with override conditions present.

Fig. 49 – Override timings (level trigger)

- Edge Trigger: override engaged on contacts closing until at least one muting sensor is

intercepted. In this case the override state rests even if the override contacts are released. The
device exits the override state when one of the following events happens:

- the muting sensors are deactivated (T-muting) or the muting sensor are deactivated AND no
beams are intercepted (L-muting)

- the timeout expires
OVERRIDE STATUS is an output signal that informs the user if the override inputs are active
with override conditions present.

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. This time can be chosen by the user
from a minimum of 1 minute to a maximum of 256 minutes.
After timeout the override ends even if the conditions for its activation are still existing and
the override inputs are active.
OVERRIDE STATUS is an output signal that informs the user if the override inputs are active
with override conditions present.

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.
When override ends if the beams are free the OSSDs go to normal operation state.
OVERRIDE STATUS is an output signal that informs the user if the override inputs are active
with override conditions present.

7.9 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.
The blanking function is therefore particularly useful when light curtain’s controlled area must
be inevitably intercepted by the material being worked or by a fixed or mobile part of the
machine. In practice, it is possible to keep light curtain’s safety outputs in a normal operation
condition and the machine working, even if a pre-determined number of beams within the
controlled area is being intercepted.
The user can even connect a lamp (whose characteristics are reported in chapter 11) to
indicate that a blanking function is active. The use of the lamp is not mandatory for a light
curtain in blanking mode. The lamp begins to blink in the following cases:

- the light curtain is in any fixed blanking mode and the object is removed from the blanked
zone

- the light curtain is in floating mode with total surveillance and the dimension of the taught
object changes or the object is removed from the blanked zone.
To activate all blanking functions Blanking Operation can be selected either in BCM or in
ACM.

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. The blanking zone
becomes active after the Teach-in contact has been released.
If Teach-in contact is kept pressed for a time greater than 1 minute the light curtain goes in a
lockout failure.
The Teach-in operation can be performed in ACM too. The user has to place the object(s)
within the protected area and press the button “Teach-in” (in “Reduced resolution / Blanking”
in the blanking section of the GUI).

ACM Configuration: Teach-in operation

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 normally­open 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. If object moves more than 1

beam out of the blanking zone ESPE locks-out in Blanking Tolerance Fault.
Tolerance function is useful if there is the possibility that the object can have little movements
from its initial position.
If the light curtain is switched off the Tolerance is lost and a new Tolerance operation
(described here above) is necessary.
With Tolerance active at least two not blanked beams must separate two blanking zones.
Teach-In Configuration is kept on both power disconnection and ESPE Reset, till next Teach­In. The user can erase the Teach-In Configuration by making a new Teach-in operation with
the controlled area free from objects.
On a Blanking Faults Teach-in configuration gets erased after Reset.
If the user changes configuration from blanking to muting and then blanking again, every
possible Teach-in zone stored at the beginning is cancelled.
Fixed Blanking can be combined with floating blanking; at least one sync beam must be free.

SG4 EXTENDED INSTRUCTION MANUAL

56

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).
Only fixed blanking zones can be set on the side of the tolerance; on the other side fixed
blanking or floating blanking with total surveillance zones are allowed.
Only one zone can be set as fixed blanking with increased tolerance.
This function can be set only by means of ACM.

Note: Tolerance affects effective ESPE resolution.

7.9.3 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.
This function can be set only by means of ACM.

7.9.4 Floating Blanking with partial surveillance

Floating Blanking with partial surveillance allows the object to move freely inside the light
curtain’s controlled area, occupying till a given number of beams, at the condition that the
occupied beams are adjacent and that their number is not higher than the configured one.
In this mode, the object may be removed from the controlled area.

This function can be set only by means of ACM.
In the figure below the different blanking configurations can be seen.

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. For example, with Reduced
Resolution 2 the object intercepts 1, 2 or no beams and the light curtain remains in Normal
Operation. This function can be set only by means of ACM.

NB: This function affects the effective resolution of the light curtain and the user is
warned about it.

7.9.6 Dimension

This value indicates the size of blanking zone.
This function can be set only by means of ACM.

7.9.7 Position

This value indicates the first beam of the blanking zone, starting from the bottom of the ESPE
(the bottom of the ESPE is the side with the leds and the push buttons).
Since in floating blanking configuration zones haven’t a fixed position, it is valid only in fixed
blanking.
This function can be set only by means of ACM.

7.9.8 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.

Dimension Tolerance

It indicates how many beams the object can be smaller than the number fixed by the value
Dimension. It’s a negative quantity.
It is useful when an object intercepts half optic; in this case a little vibration can make the
OSSDs change status.

Tolerance can be selected via wire or ACM.
If the user wants to select this function with ACM, he must have at least one blanking zone;
then he can choose Position or Dimension Tolerance. Next tables shows the different cases
on a blanking zone of 3 beams.
If the light curtain is configured with ACM it doesn’t take care if the Tolerance has been
selected by means of Tolerance wire (pin 9 of M12-12 poles - RX).

FLOATING BLANKING WITH TOTAL SURVEILLANCE

Floating objects can move up or down intercepting different beams while moving; the objects
can’t overlap nor change relative positions.
Object must be always present in the protected area and intercept the configured number of
beams with a mandatory fixed tolerance of one beam; that is necessary since a moving
object will always intercept a different number of beams.

FLOATING BLANKING WITH PARTIAL SURVEILLANCE

Floating objects can move up or down intercepting different beams while moving; they can

Adjacent to this zone fixed blanking only can be configured; with such fixed blanking zones
floating objects can overlap and even change relative positions without causing the switching
of the OSSDs.

FUNCTIONS

7.10 CASCADE

A dedicated Bus provides the connection between master and slave units. The same bus is
used to connect SG-Dongle which links the light curtain to Ethernet.
A proprietary transmission protocol for bus is used to communicate to slaves safety related
informations and status.
OSSDs are physically connected to master unit only; only the master unit can control their
status.
If transmission fails, due to a stuck-at fault or a signal degradation, master and slave units go
in failure lock-out condition.
A maximum of three units (master and two slaves) can be connected in a cascade
configuration (a maximum of 160 beams for 30mm resolution models and a maximum of 320
beams for 14mm resolution models). The maximum length of the master unit is 1800mm and
the maximum length of each slave is 1200mm. For the correct connection of the units in a
cascade configuration, the right cables have to be used (CVL-5193, CVL-5194, CVL-5195 on
chapter 15).
A safe auto-recognition procedure at startup is implemented; it automatically detects cascade
topology and correctly address units.
In order to allow auto-recognition it’s mandatory to connect the termination cap (supplied on
kit) on the tail connector of last cascade unit, in both transmitter and receiver unit.

7.12 CODING

The coding function allows the ESPE to remain in normal operation also when an
interference condition with an other ESPE occurs, and in particular when the TX of the first
light curtain radiates in the direction of the RX of the second light curtain. Obviously, both

light curtains must be configured with two different codes (see also par. 2.2.2).

No code

In this situation, no code is selected and the safety light curtain has to be installed

at a

certain distance from other light curtains with no code, in order to avoid possible
interferences that can lead to a dangerous situation.
If the user has to install the light curtains nearer than the minimum allowed distance he
should take care to install the TX of the first light curtain on the same side of the RX of the
second.

Fig. 59 – No code

Code 1 or Code 2

When the user has to install two light curtains at a distance that is lower than the minimum
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.
The configuration by means of GUI changes the code only on RX side; in order to have the
light curtain correctly working, the user has to configure TX side with the same code by
means of BCM.

9 PERIODICAL CHECKS

The following is a list of recommended check and maintenance operations that should be
periodically carried-out by qualified personnel (see also par 2.2.5).

Check that:

 The ESPE stays in SAFE state during beam interruption along the entire protected

area, using the specific Test Piece (TP-14 or TP-30)

 The ESPE is correctly aligned. Press slightly product side, in both directions and the

red LED (named OSSD on RX side) must not turn ON

 Enabling the TEST function (on TX side), the OSSD outputs should open (the red

LED, OSSD on RX side, is ON and the controlled machine stops)

 The response time upon machine STOP (including response time of the ESPE and of

the machine) is within the limits defined for the calculation of the safety distance (see
chapter 2)

 The safety distance between the dangerous areas and the ESPE are in accordance

with the instructions included in chapter 2

 Access of a person between ESPE and machine dangerous parts is not possible nor

it is possible for him/her to stay there

 Access to the dangerous area of the machine from any unprotected area is not

possible

 The ESPE and the external electrical connections are not damaged

The frequency of checks depends on the particular application and on the operating
conditions of the safety light curtain.

9.1 GENERAL INFORMATION AND USEFUL DATA

Safety MUST be a part of our conscience.

The safety devices fulfil their safety function only if they are correctly installed, in accordance
with the Standards in force. If you are not certain to have the expertise necessary to install
the device in the correct way, Datalogic Automation Technical Support is at your disposal to
carry out the installation.

The device uses fuses that are not self-resetting. Consequently, in presence of short-circuits
causing the cut-off of these fuses, both units shall be sent to Datalogic Automation Repair

Service

.

A power failure caused by interferences may cause the temporary opening of the outputs,
but the safe functioning of the light curtain will not be compromised.
