Safety

SAFETY

SIMBOLOGY

 This symbol indicates an important warning for personal safety. Failure to comply with this warning

may result in high level risk for exposed personnel.

Î This symbol indicates an important warning for the proper operation of the curtain.

PRECAUTIONS

 The operations indicated in this document must only be carried out by qualied personnel. Such

personnel must have the necessary requirements to be able to operate on the electronic equipment
to be installed in order to avoid any risky situation.

REER declines any liability for malfunctioning of equipment installed by unqualied sta.

 Any use other than those indicated in this manual may be considered as potentially dangerous for

the installer and the machine operator.

 For safety reasons, please contact your country’s safety authorities or the relevant industry

association if necessary.

 For applications in the food industry, consult the manufacturer to verify compatibility between

curtain materials and chemical agents used.

 The protective function of optoelectronic safety devices is not eective in cases where:

¾ The machine stopping device cannot be actuated electrically and it is not possible to stop all dangerous

machine movements immediately and at any time during the operating cycle.
¾ The hazardous condition is associated with the falling of objects from above or ejection of these from

the machine.
¾ Anomalous forms of light radiation are present (for example, use of cablelless control devices on cranes,

radiation from weld spatter, etc). In this case additional measures may be necessary to ensure that the

ESPE does not fail to danger.

Î The strict and complete observance of all the standards, indications and prohibitions set forth in this

manual is a prerequisite for its proper operation.

REER S.p.A. therefore, declines any liability in case of non-respect, even partial, of these indications.

Safety

CAUTIONS BEFORE INSTALLATION

Before installing the SAFEGATE safety system, you must verify all of the conditions listed below:

 The protection level (Type4, SIL3, SILCL3, PLe) of the SAFEGATE system must be compatible with

the danger level of the system to be controlled.

 The safety system should only be used as a stop device and not as a device for controlling the

machine.

 The machine control must be electrically actuated.

 It must be possible to immediately stop any dangerous operation of the machine.

In particular, the machine stopping times must be known and, if necessary, measured.

 The machine must not generate hazardous situations due to projection or fall of materials from

above; otherwise it is necessary to provide additional mechanical protections.

 The minimum size of any object to be intercepted must be greater than or equal to the resolution of

the selected model.

The knowledge of the shape and size of the hazardous area allows an estimation of the width and the

height of its access area:

 Compare these dimensions with the maximum working range and the height of the area guarded by

the model used.

Before placing the safety device, it is important to consider the following general guidelines:

 Verify that the temperature of the environment where the system is installed is compatible with the

temperature operating parameters indicated on the product label and in the technical data.

 Avoid positioning the Emitter and Receiver near intense or ashing high-intensity light sources.

 Specic environmental conditions may aect the level of detection of photoelectric devices.

In environments where fog, rain, smoke or dust may be present, it is advisable to use suitable Fc

correction factors at the maximum useful values of the working range to ensure the correct operation

of the equipment. In these cases:

Pu = Pm x Fc

where Pu and Pm are respectively the working range and maximum range in metres.

Recommended Fc factors are shown in the following table.

ENVIRONMENTAL CONDITION CORRECTION FACTOR Fc

Fog 0,25

Steam 0,50

Powders 0,50

Dense smoke 0,25

 If the device is placed in environments subject to sudden temperature uctuations, it is imperative

to take the appropriate steps to avoid condensation on the lenses, which may impair the detection
capability.

The Muting function

THE MUTING FUNCTION

The Muting function is the temporary exclusion of the safety curtain, automatically and safely carried out
based on the machine cycle.

ÎÎ Carefully verify your risk analysis to make sure the Muting function is compatible with your

application and what additional measures should be taken.

There are basically two types of applications:

1. Those allowing people to enter the dangerous area during the non-dangerous part of the machine
cycle.

Example:
Positioning or Removing the workpiece

Depending on the position of the tool, which is the hazardous
element, one of the two curtains (the one facing the tool
work area) is active while the other is in Muting condition
to allow the operator loading/unloading the workpiece. The
Muting condition of the two curtains will then be reversed
when the tool is to work on the opposite side of the machine.

2. Those who allow material transit and prevent access to the people.

Example: Pallet exit from the hazardous area

The safety curtain is equipped with Muting sensors able to

e󰀨ectively discriminate between the person and the material

allowed to get through the controlled gate. The essential
requirements concerning the Muting function are described

in the following Standards:

ÎÎ IEC TS 62046 - “Application of protection devices for people

General requirements:

¾ The Muting function is a temporary suspension of the safety function that needs to be activated and

deactivated automatically.

¾ The activation and subsequent deactivation of the Muting function must take place only through the use

of two or more wired and independent signals activated by a correct timing or spatial sequence. This
means that a stand-alone failure cannot activate the Muting function.

¾ It should not be possible to activate the Muting function when SAFEGATE has deactivated the safety

outputs.

¾ It should not be possible to start a Muting function by switching o󰀨 and then restarting the device.
¾ Muting must be activated at an appropriate point of the machine cycle, i.e. only when there are no risks

for the operator.

¾ Muting sensors must be mechanically protected so that any impact does not modify their alignment.

The Muting function

A) 2 INTEGRATED CROSS MUTING SENSORS, ONLY FOR PALLET OUTPUTS (LX)

In this way sensors 1 and 2 are on the same side as the vertical curtain and are placed in front of the
dangerous gate. This mode is unidirectional and is useful for protecting gates with pallet output.
The activation of the Muting function occurs after the simultaneous interruption (within 4 sec maximum) of

S1 and S2 sensors. As long as both sensors remain busy, the Muting function continues. When the rst of

the 2 sensors is released, the material will still have 4 seconds to leave the protected area limited by the
curtain. The Muting condition will be disabled as soon as the protected area is released.
At the end of 4 seconds, if the curtain is still busy, the OSSD outputs are disabled by interrupting the
operation of the machine. This allows selecting the maximum duration of the Muting condition (timeout) as
30 seconds or 9 hours.

ÎÎ Other timings are available with programmable programs.
Î For the safe operation of the LX conguration, it is absolutely essential that the horizontal Muting

sensor elements are located within the hazardous area.

Î The minimum distance between two consecutive pallets must be less than 10 cm or greater than

32cm.

D) 4 INTEGRATED PARALLEL MUTING SENSORS, FOR BI-DIRECTIONAL GATES (T4)

This mode is bidirectional and is useful for protecting gates with pallet output.

Using this mode, two di󰀨erent modes of operation are outlined:

Concurrent

The activation of the Muting function occurs after the sensors S1 and S2 are interrupted (within max 4sec)
(or S4 and S3 with material moving in the opposite direction).
The Muting state ends after the release of the gate, and of the S3 sensor (or S2 with material moving in
the opposite direction).

ÎÎ For the T4 models (concurrent operation), there are two available timeouts: 1) 30 sec; 2) 9 hours.

Sequential

The activation of the Muting function occurs after the sequential interruption of sensors S1 and S2 (or S4
and S3 with material moving in the opposite direction) without time limitations.
The Muting state ends after the release of the gate, and of the S3 sensor (or S2 with material moving in

The Muting function

PARTIAL MUTING

The Partial Muting feature allows you to limit the

Muting function to a number of well-dened beams.

By this function, you can enable the Muting function
only for those beams that will be interrupted by the
passage of the material (e.g. lower pallets at the end
of the product cycle). The remaining beams, however,
can be kept active to protect the dangerous gate.

ÎÎ This function is only available on SMP/SMPO

models and must be managed through the

Safegate Congurator software (select “Partial

Muting Enabling”).

The software should then select the number of beams a󰀨ected by Partial Muting, taking into account that
the rst Partial Muting beam always starts from the bottom (connectors side).

For this operation, it may be useful to verify the
Monitor software function (free beams are indicated

by di󰀨erent colouring than the busy ones) and the

various numerical information on the side (LBO,
FBO, etc.).
Only one value can be entered when programming

the number of beams a󰀨ected by this function.

There are two types of partial Muting and, for both,
the “Partial Muting” input pin (pin 6 of M12 12-pin
connector on the receiver) must be used.

Partial Muting with Enable

With this option, the Partial Muting function is normally deactivated. To activate this function, the input
signal (pin 6 of the receiver) must switch from LO to HI (rising edge) before starting the Muting cycle.

Partial Muting with Disable

With this option the Partial Muting function is normally active. To activate this function, the input signal (pin
6 of the receiver) must switch from LO to HI (rising edge) before starting the Muting cycle.

ÎÎ Refer to the “OPERATING MODES” section to correctly set this function.

The Muting function

MUTING OVERRIDE

The OVERRIDE function becomes necessary when, after incorrect Muting activation sequences, the
machine stops leaving the material in the dangerous gate.
In this situation, the OSSD outputs are inactive because the curtain and/or at least one Muting sensor are

busy. In this condition, the OVERRIDE request LED ashes.

Î This operation activates the OSSD outputs to remove the material obstructing the gate.
Î During the entire phase in which the OVERRIDE function is active, the Override/Muting lamp ashes.

You should periodically verify the eciency of this lamp (during Muting or Override phases).

Î The Pulse Override command automatically activates the curtain outputs until both the curtain and

the Muting sensors are again free of obstacles. During this period the curtain is not able to protect
access to the dangerous gate. It is therefore necessary that all operations be conducted under close
supervision of experienced personnel.

The user will use the type of Override previously congured:

1. Override with spring return key

2. Override with pushbutton

Override with spring return key

Activation of this function must be done by bringing both receiver pins 9 and 10 to + 24VDC (within a 400

ms time window), for example by using a 2-way key switch with spring return.

Override has a maximum duration of 15 minutes; it can end due to two di󰀨erent causes.

1. When the selector is released or the 15 minutes expire, the override ends, bringing the outputs to

OFF, turning o󰀨 the lamp, and returning the display to normal. However, it is still possible to start a

new override, releasing the selector and reactivating it.

2. At the release of the curtain and sensors (clear gate) the override ends and the GUARD condition is
reactivated (the curtain is working properly) without additional commands.

Override with pushbutton

The activation of this function must occur inverting (within a time window of 400 ms) the condition of pins
9 and 10 of the receiver through the use of a 2-way switch.

When override is active the condition of pins 9 and 10 is no longer veried.

MAXIMUM OVERRIDE TIME (MODELS WITH HARDWARE CONFIGURATION)

The override has a maximum duration of 15 minutes (repeatable).

The function can only restart if the button is pushed again (complying with the following conditions):

1. Maximum OVERRIDE time (after n consecutive requests) = 60 min

2. Maximum number of consecutive OVERRIDE requests = 30.

MAXIMUM OVERRIDE TIME (MODELS WITH SOFTWARE CONFIGURATION)

The function can only restart if the button is pushed again (complying with the following conditions):

1. Maximum OVERRIDE time (after n consecutive requests) = 4 x timeout override

2. Maximum number of consecutive OVERRIDE requests = 30.

At the release of the curtain and sensors (clear gate) the override ends and the GUARD condition is
reactivated (the curtain is working properly) without additional commands.

The timer (point 1) and the counter (point 2) are reset if one of the following conditions occurs:

¾ A proper sequence of Muting.
¾ A system reset (turning it o󰀨 and on).

CALCULATION OF THE SAFETY DISTANCE

The e󰀨ectiveness of the protection heavily depends

on the correct positioning of the curtain according
to the danger. The curtain must be positioned at a
distance greater than or equal to the minimum safety
distance S so that reaching the dangerous point can
only be achieved after the dangerous operation of the
machine has stopped.

The positioning shall be such that:

• Reaching the dangerous point is avoided without

crossing the area controlled by the curtain.

• No person is allowed in the dangerous area

without this being detected. For this case,
additional safety devices (e.g. horizontal light
curtains) may be required.

USE OF DEFLECTING MIRRORS

For the protection or control of multiple accessed areas, one or more deecting mirrors can be used in

addition to the Emitter and the Receiver.
The deecting mirrors allow in fact returning the optical beams generated by the Emitter on
multiple sides.

If you want to deect by 90° the beams emitted by the Emitter, the perpendicular to the surface of the
mirror should make a 45° angle with the direction of the beams.
The following gure shows an application in which two deecting mirrors are used to make a “U” protection.

Dangerous zone

S

S

When making use of deecting mirrors consider the following rules:

¾ Position the mirrors so that the minimum safety distance S is kept on each of the sides to access the

hazardous area.

¾ The working distance (range) is the sum of the lengths of all sides accessing the guarded area.

(Please note that the maximum working range between Emitter and Receiver is reduced by 15% for

each mirror used).
¾ When installing, pay particular attention to not to twist along the longitudinal axis of the mirror.
¾ Verify, by positioning near and on the Receiver axis, that in the rst mirror you see the whole shape of

the Emitter.
¾ It is recommended that you use no more than three deecting mirrors.

DISTANCE FROM REFLECTING SURFACES

Î The presence of reective surfaces located near the light curtain

can cause spurious reections preventing the detection. Referring to the

S

A

following Figure object A is not detected due to the plane S reecting the

beam and thus closing the optical path between the Emitter and Receiver.
It is therefore necessary to keep a minimum distance d between any

reecting surfaces and the protected area. For calculating the minimum

distance d, it is recommended to use the values set for Type 4 devices
according to IEC/EN 61496-2.

The following gure shows the above-mentioned values of the distance d

based on the distance between the Emitter and the Receiver.

MECHANICAL ASSEMBLY AND OPTICAL ALIGNMENT

Î The following operations must only be carried out by qualied personnel, otherwise you may lose

the machine safety function.

¾ The Emitter and the Receiver must be mounted one in front of the other at a distance equal to or less

than that indicated in the technical data; Using the supplied inserts and brackets, position the Emitter

and the Receiver so that they are aligned and parallel to each other and with the connectors facing the

same side.

¾ The perfect alignment between Emitter and Receiver is essential for the smooth operation of the curtain;

this operation is facilitated by observing the Emitter and Receiver signalling LEDs.

¾ Make electrical connections according to the directions of the dedicated chapter.

ÎÎ Pay particular attention to the SAFEGATE model you are connecting.

Connections may vary depending on the model.

¾ Place the optical axis of the rst and last beams of the Emitter on the same axis as that of the

corresponding beams on the Receiver.

¾ Move the Emitter to nd the area within which the green LED on the Receiver stays on, then place the

rst transmitter beam (the one near the signal LED) at the centre of this area.

¾ Using this beam as a pivot, with small lateral displacements of the opposite end, move to the free

guarded area condition, which in this situation will be indicated by turning on the green LED on the

Receiver.

¾ Firmly tighten the Emitter and the Receiver.

ÎÎ If the Emitter and the Receiver are mounted in areas subject to strong vibrations, in order not to

compromise the operation of the circuits, it is necessary to use anti-vibration dampers.

Î Using LX or TX conguration with 2 sensors: SENSOR1 wiring is mandatory, while the position of the

second muting sensor is the operator’s choice between SENSOR2 and SENSOR3.

TEST FUNCTION

By means of the test function, which simulates occupation of the protected area, it possible to verify the
operation of the entire system by means of an external supervisor (e.g. PLC, control module, etc.). The
SAFEGATE barrier system features an automatic self-diagnosis function that enables it to detect response
time malfunctions (this time is declared for each model).
This safety system is permanently active and does not require any interventions from the outside.
The TEST function is available should the user wish to check equipment connected downstream of the
barrier (without physically entering the protected area). By means of this function the OSSDs can be
switched from ON to OFF as long as the function remains active.

Î The minimum duration of the TEST function must be 40 msec.

SELECTION OF OPERATING MODES

The inputs available to the SAFEGATE receiver (main male connector - M12 - 12pin) allow the conguration

of the various operating modes.
It is therefore necessary, when switching on, to properly connect the SAFEGATE receiver inputs for proper
operation, as shown below.

The following tables allow the user to congure the type of Muting to be adopted in terms of: MUTING

RESTART (MANUAL OPERATION)

Pin 10 has RESTART function. As a result of occupation of the protected area, outputs will be deactivated

(Manual mode - start/restart interlock enabled). To reactivate them you will need to repeat the sequence:

¾ “0Vdc” → “24Vdc” → “0Vdc”.
¾ The high level (24Vdc) must be between 100 ms and 5 s.

RESTART

 Use in manual mode (start/restart interlock enabled) is mandatory in case the safety device

controls a gate to protect a dangerous area and a person, once crossed the gate, can stay
in the hazardous area without being detected (use as a ‘trip device’ according to IEC 61496).

 The Restart command must be located outside the hazardous area, at a point where the

hazardous area and the entire working area concerned are clearly visible.

 It must not be possible to reach the command from inside the hazardous area.

AUTOMATIC OPERATION

Thanks to the connection of the pin 10 on the main receiver connector, the operator can choose to enable
the AUTOMATIC operation.

In Automatic operating mode, the OSSD1 and OSSD2 safety outputs follow the status of the light curtain:

¾ with guarded area free, the outputs are ON.
¾ with guarded area occupied, they are OFF.

OVERRIDE1
RESTART (10)

 If the SAFEGATE light curtain is used in AUTOMATIC mode, it will not be equipped with

a start/restart interlock circuit. In most applications, this safety function is mandatory.
Carefully evaluate the risks analysis of your own application.

TEST FUNCTION

By means of the test function, which simulates occupation of the protected area, it possible to verify the
operation of the entire system by means of an external supervisor (e.g. PLC, control module, etc.).
The SAFEGATE barrier system features an automatic self-diagnosis function that enables it to detect
response time malfunctions (this time is declared for each model).
This safety system is permanently active and does not require any interventions from the outside. The
TEST function is available should the user wish to check equipment connected downstream of the barrier
(without physically entering the protected area). By means of this function the OSSDs can be switched
from ON to OFF as long as the function remains active.

Î The minimum duration of the TEST function must be 40 msec.

OVERRIDE (PC PROGRAMMING)

SAFEGATE allows the operator to congure two di󰀨erent types of override; (See paragraph “MUTING

OVERRIDE”, page 23 for the description of the following function).

OVERRIDE1 (pin 10) OVERRIDE2 (pin 9) SELEZIONE

0 0 Override with spring return key

0 1 Override with button

OVERRIDE WITH SPRING RETURN KEY

Thanks to the programming software, the operator can choose what kind of OVERRIDE enable (in this
case SPRING RETURN KEY) and its timeout.

Î With sensors occupied: When selected, it generates a

condition for which even after the gate is clear, but with at
least one sensor occupied the curtain remains in BREAK
condition with an OVERRIDE request.

The function starts with the simultaneous activation of the two

OVERRIDE inputs according to the following table:

OVERRIDE1 (pin 10) OVERRIDE2 (Pin 9)

0 0

1 1

Both signals are active at 24VDC and the function only starts if they are activated at the same time (within
a maximum delay of 400 ms) and the key is kept active for at least 400 ms.

OVERRIDE WITH PUSHBUTTON

Thanks to the programming software, the operator can choose what kind of OVERRIDE enable (in this
case PUSHBUTTON) and its timeout.

Î With sensors occupied: When selected, it generates a

condition for which even after the clearance of the gate,
but with at least one sensor occupied the curtain remains
in BREAK condition with an OVERRIDE request.

The function starts with the simultaneous activation of the two

OVERRIDE inputs according to the following table:

OVERRIDE1 (pin 10) OVERRIDE2 (Pin 9)

0 1

1 0

The function starts only if the signals are activated at the same time (within a maximum delay of 400 ms)
and the button is held pressed for at least 400 ms.

Electrical connections/Operating modes

RESTART (MANUAL OPERATION)

The choice between MANUAL or AUTOMATIC mode of operation is possible thanks to the SAFEGATE
CONFIGURATOR software. In Manual mode Pin 10 has RESTART function.
As a result of occupation of the protected area, outputs will be deactivated (start/restart interlock enabled).

To reactivate them you have to repeat the sequence:

¾ “0Vdc” → “24Vdc” → “0Vdc”.
¾ The high level (24Vdc) time must be between 100 ms and 5 s.

 Use in manual mode (start/restart interlock enabled) is mandatory in case the safety device

controls a gate to protect a dangerous area and a person, once crossed the gate, can stay
in the hazardous area without being detected (use as a ‘trip device’ according to IEC 61496).

 The Restart command must be located outside the hazardous area, at a point where the

hazardous area and the entire working area concerned are clearly visible.

 It must not be possible to reach the command from inside the hazardous area.

AUTOMATIC OPERATION

The choice between MANUAL or AUTOMATIC mode of operation of the is achieved thanks to the
SAFEGATE CONFIGURATOR software.

In Automatic operating mode, the OSSD1 and OSSD2 safety outputs follow the status of the light curtain:

¾ with guarded area free, the outputs are ON.
¾ with guarded area occupied, they are OFF.

 If the SAFEGATE light curtain is used in AUTOMATIC mode, it will not be equipped with

a start/restart interlock circuit. In most applications, this safety function is mandatory.
Carefully evaluate the risks analysis of your own application.

Electrical connections/Operating modes

MUTING ENABLE

SAFEGATE can be congured in such a way that the muting cycle only starts after a signal of valid

MUTING ENABLE. Thanks to the programming software, the operator can choose to enable the MUTING
ENABLE signal (in this case MUTING ENABLE active).

Muting Enable active: correct Muting sequence

MUTING ENABLE/DISABLE

SAFEGATE can be congured in such a way that the muting cycle only starts after a signal of valid

MUTING ENABLE/DISABLE. Thanks to the programming software, the operator can choose to enable the
MUTING ENABLE signal (in this case MUTING ENABLE/DISABLE active).

Muting Enable/Disable active: Correct Muting sequence

Electrical connections/Operating modes

PARTIAL MUTING

Two types of partial Muting are distinguished and, for both, the “Partial Muting” input pin (pin 6 of the M12
connector of the receiver) must be used.

1) Partial Muting with Enable

With this option, the Partial Muting function is normally deactivated. To activate this function, the input
signal (pin 6 of the receiver) must switch from LO to HI (rising edge) before starting the Muting cycle.

The variation of this input signal enables the Partial Muting function only for the rst n selected beams
(e.g. with 10 beams as in gure below).

Î This activation only applies to a STAND-ALONE MUTING CYCLE; It is therefore necessary to reconrm

Partial Muting activation before any new Muting function request (refer to the timing below).

2) Partial Muting with Disable

With this option the Partial Muting function is normally active (e.g. with 10 beams as in gure below).

To activate this function, the input signal (pin 6 of the receiver) must switch from LO to HI (rising edge)
before starting the Muting cycle. The changing of that input signal therefore disables the Partial Muting
function.

Î This activation only applies to a STAND-ALONE MUTING CYCLE; it is therefore necessary to reconrm

the partial Muting deactivation before any new Muting function request (refer to the timing below).

Conguration software

SETTING MUTING PARAMETERS

“Concurrent” Muting

ÎÎ The activation of the Muting function occurs as a result of the interruption of the sensors S1 and

S2 (the order is not relevant) within a time between 2s and 5s decided by the operator, (or S4 and
S3 with material moving in the opposite direction). Contemporaneous Muting enables the muting
function to be activated by the S1, S2, S3 and S4 inputs. Preliminary condition: The Muting cycle can
start if all sensors are at 0VDC and the light curtain is free.

Parameters

With_Enable:

signal of "MUT_ENABLE" (Muting Enable).
Otherwise, the Muting function is always enabled. Enable can

be of two types: Enable/Disable and Enable Only. If you select

it "Enable/Disable" the Muting cycle cannot start if Enable

is xed at 24VDC or 0VDC but it is activated only with one

rising edge, if you want to disable the muting, the signal must
be returned to 0VDC. In this way, the detected falling edge
disables Muting in any condition. If you select it "Enable only"
there is no way to disable Muting over the entire duration of the
function, but you must always return Enable to 0VDC to allow
a new rising edge for the next Muting cycle (refer to the "Partial
Muting" section).

If checked, it is possible to read the external

Muting Timeout: Allows you to set the time, variable from 10

sec to innity, within which the Muting cycle must end, if when

the cycle is not yet over, Muting is disabled immediately.

Concurrent Time Sensors: You can set the maximum time (2 to 5 seconds) that must be between the

activation of two muting sensors.

Gap Sensor: With non - homogeneous pallet materials and possible "holes" in the interruption of the

muting, this parameter allows ltering in the fall of the sensor signal leaving then the muting sequence

unchanged. This parameter can be 500 ms or 1000 ms.

Position S2: Not allowed.
Direction: You can set the occupancy order of the sensors; if set BIDIR the occupation can take place in

both directions from S1 & S2 to S3 & S4 or reverse order; if you choose UP the occupancy order is: S1 &
S2 to S3 & S4 and eventually with DOWN the occupancy order is: S4 & S3 to S2 & S1.

Muting Closure: It can be of two types CURTAIN and SENSOR. By selecting CURTAIN, muting closes at

the release of the protected gate, while with SENSOR closure occurs after the release of the last but one
sensor.

Blind Time: Only with Muting Closure = Curtain, blind time is triggered if it is known that after the complete

transit of the pallet (muting cycle closure) objects may be protruding and occupy the curtain, sending the
curtain to BREAK status. During blind time, OSSD outputs remain active. The Blind Time may vary from
250 ms to 1 second.

Minimum Sensor Time: If selected, it allows Muting activation only if it is time >150 ms between activation

of sensor 1 and sensor 2 (or sensor 4 and sensor 3).

Obligatory Lamp: If selected, the Muting lamp is compulsory.

Conguration software

“Sequential” Muting

ÎÎ The activation of the Muting function occurs following the sequential interruption of the sensors

S1 and S2, and the sensors S3 and S4. If the pallet proceeds in an opposite direction the correct
sequence is: S4, S3, S2, S1.

Parameters

With_Enable:

signal of "MUT_ENABLE" (Muting Enable). Otherwise, the

Muting function is always enabled. Enable can be of two types:

Enable/Disable and Enable Only. If you select it "Enable/
Disable" the Muting cycle cannot start if Enable is xed at

24VDC or 0VDC but it is activated only with one rising edge, if
you want to disable the muting, the signal must be returned to
0VDC. In this way, the detected falling edge disables Muting in
any condition. If you select it "Enable Only" there is no way to
disable Muting over the entire duration of the function, but you
must always return Enable to 0VDC to allow a new rising edge
for the next Muting cycle (refer to the "Partial Muting" section).

If checked, it is possible to read the external

Muting Timeout: Allows you to set the time, variable from 10

sec to innity, within which the Muting cycle must end, if, when

the cycle is not yet over, Muting is disabled immediately.

Gap Sensor: With non-homogeneous pallet materials and

possible "gaps" in the interruption of muting, this parameter allows ltering the drop of the sensor signal

leaving then the muting sequence unchanged. This parameter can be 500 ms or 1000 ms.

Position S2: Not allowed.
Direction: You can set the occupancy order of the sensors; if set BIDIR the occupation can take place in

both directions from S1 & S2 to S3 & S4 or reverse order; if you choose UP the occupancy order is: S1 &
S2 to S3 & S4 and eventually with DOWN the occupancy order is: S4 & S3 to S2 & S1.

Blind Time: Only with Muting Closure = Curtain, blind time is triggered if it is known that after the complete

transit of the pallet (muting cycle closure) objects may be protruding and occupy the curtain, sending the
curtain to BREAK status. During blind time, OSSD outputs remain active. The Blind Time may vary from
250 ms to 1 second.

Number Beams: Makes it possible to select the number of beams that can be a󰀨ected by Muting (if Partial

Muting is active).

Muting Closure: It can be of two types CURTAIN and SENSOR. By selecting CURTAIN, muting closes at

the release of the protected gate, while with SENSOR, closure occurs after the release of the last but one
sensor.

Obligatory Lamp: If selected, the Muting lamp is compulsory.

“L” Muting

ÎÎ The activation of the Muting function occurs as a result of the interruption of sensors S1 and S2 (the

order is not relevant) within a time between 2s and 5s decided by the operator.
The status of Muting ends after the release of the gate.

Parameters

With_Enable:

signal of "MUT_ENABLE" (Muting Enable).
Otherwise, the Muting function is always enabled. Enable

can be of two types: Enable/Disable and Enable Only. If you

select "Enable/Disable" the Muting cycle cannot Start if

Enable is xed at 24VDC or 0VDC but is activated only by a

rising edge; if you want to disable the muting, the signal must
be returned to 0VDC. In this way, the detected falling edge
disables Muting in any condition. If you select "Enable only"
there is no way to disable Muting over the entire duration of
the function, but you must always return Enable to 0VDC to
allow a new rising edge for the next Muting cycle (refer to the

Time Simultaneous Sensors: You can set the maximum time (2 to 5 seconds) that must be between the

activation of two muting sensors.

Sensor Gap: With non - homogeneous pallet materials and possible "holes" in the interruption of the

muting, this parameter allows ltering in the fall of the sensor signal leaving then the muting sequence

unchanged. This parameter can be 500 ms or 1000 ms.

Position S2: The Position S2 parameter allows the operator to select the connector (blue or red) to which

the external Muting S2 sensor must be connected. The blue connector must be selected using integrated
L-arms (with output on a single connector). Using two separate sensors (with 2 connectors) the operator
must select the red connector.

Muting end time: You can set the (from 2.5 to 6 seconds, with 500 ms steps) that must be between the

release of the rst sensor and the release of the dangerous gate. At the end of this time the Muting function

ends.

Blind Time: Only with Muting Closure = Curtain, blind time is triggered if it is known that after the complete

transit of the pallet (muting cycle closure) objects may be protruding and occupy the curtain, sending the
curtain to BREAK status. During blind time, OSSD outputs remain active. The Blind Time may vary from
250 ms to 1 second.

Minimum Sensor Time: If selected, it allows Muting activation only if it is time >150 ms between activation

of sensor 1 and sensor 2 (or sensor 4 and sensor 3).

Obligatory Lamp: If selected, the Muting lamp is compulsory.

“T” Muting

ÎÎ The activation of the Muting function occurs as a result of the interruption of the sensors S1 and S2

(the order is not relevant) within a time between 2s and 5s decided by the operator.
The status of Muting ends after the release of the gate.

Parameters

With_Enable:

signal of "MUT_ENABLE" (Muting Enable). Otherwise, the

Muting function is always enabled. Enable can be of two types:

Enable/Disable and Enable Only. If you select it "Enable/

Disable" the Muting cycle cannot start if Enable is xed at

24VDC or 0VDC but it is activated only with one rising edge, if
you want to disable the muting, the signal must be returned to
0VDC. In this way, the detected falling edge disables Muting in
any condition. If you select it "Enable only" there is no way to
disable Muting over the entire duration of the function, but you
must always return to 0VDC Enable to allow a new rising edge
for the next Muting cycle (refer to the "Partial Muting" section).

If checked, it is possible to read the external

Muting Timeout: Allows you to set the time, variable from 10

sec to innity, within which the Muting cycle must end, if When

the cycle is not yet over, Muting is disabled immediately.

possible "holes" in the interruption of the muting, this parameter

allows ltering in the fall of the sensor signal leaving then the

Position S2: The Position S2 parameter allows the operator to select the connector (blue or red) to which

the external Muting S2 sensor must be connected. The blue connector must be selected using sensors
with output on a single connector. Using two separate sensors (with 2 connectors) the operator must select
the red connector.

Minimum sensor time: If selected, it is only possible to activate Muting if a time > 150 ms elapses between

the activation of Sensor 1 and Sensor 2 (or Sensor 4 and Sensor 3).

PARTIAL MUTING

A SAFEGATE function concerns the possibility of limiting the muting function to a number of well-dened
beams (from the rst beam).
This function, called Partial Muting, has the following features:

ÎÎ It can only be enabled with the Safegate Congurator SOFTWARE:

(Tick on "Partial Muting Enabling").

ÎÎ The rst beam of the Partial Muting always starts from the bottom (connection side).

Partial Muting with Enable

When Partial Muting with ENABLE is selected after a "PARTIAL Muting" signal rising before the start of the

Muting cycle, SAFEGATE enables the Partial Muting function only for the rst n beams (10 in the example).

Partial Muting with Disable

When Partial Muting with DISABLE is selected, SAFEGATE enables the Partial Muting function only for

the rst n beams (10 in the example).

Only after a "PARTIAL Muting" signal occurs before the start of the Muting cycle will the Muting Normal
cycle be enabled.

Partial Muting: MONITOR

At this stage we have a dynamic reading of the
SAFEGATE condition.

In particular, they are highlighted:

¾ A graphic representation of the curtain, with

integrated lamp with colour in real time.

¾ A graphic representation of the signalling

label.

¾ A graphical representation of the curtain, with

highlighted beams for Partial muting function

ÎÎ Pay attention to the two highlighted zones in the boxes: in the example, the Partial muting option for

the rst 10 beams was selected. THE BEAMS WITH Partial Muting FUNCTION ARE HIGHLIGHTED IN

YELLOW, WHILE GREEN COLOURED BEAMS WORK NORMALLY: ACTIVE CURTAIN.

MUTING OVERRIDE

ÎÎThe OVERRIDE function becomes necessary when,

after incorrect Muting activation sequences, the machine
stops with the dangerous hazardous material.

Î In this situation, the OSSD outputs are inactive because the curtain and/or at least one Muting sensor

are occupied. In this condition, the OVERRIDE request LED ashes. This operation activates the

OSSD outputs make it possible to remove the blocking material; In addition, the Override/Muting

lamp ashes.

Î During the entire phase in which the OVERRIDE function is active, the Override/Muting lamp ashes.

You should periodically verify the eciency of this lamp (during Muting or Override phases).

Î Warning! The Pulse Override command automatically activates the curtain outputs until both the

curtain and the Muting sensors are again free of obstacles. During this period the curtain is not able
to protect access to the dangerous gate. It is therefore necessary that all operations be conducted
under close supervision of experienced personnel.

Override can only be activated if Muting is not active and at least one Muting sensor is occupied (or if the
curtain is busy). At the release of the grid and sensors the Override ends.

Override can be congured in two ways:

¾ Pulse with maintained action.
¾ Impulse.

Override with spring return key

Activating this function must be done by keeping the Override command active for the duration of
subsequent operations. However, it is still possible to start a new override be de-activating and re-activating
the command. At the release of the grid and sensors (clear gate) or the timeout expiration, the Override
terminates without additional commands.

Impulse override

Activating this function occurs by activating the Override command.
At the release of the grid and sensors (clear gate) or the timeout expiration, the Override terminates. The
function can only resume if the Override command is switched on again.

Parameters

With sensors occupied:

gate, but with at least one occupied sensor the curtain remains in BREAK condition with an OVERRIDE
request.

When selected, it generates a condition for which even after the clearance of the

Timeout: It allows you to set the time, which varies from 10 seconds to innity, within which the function

Override must end.

Controls, care and maintenance

CONTROLS, CARE AND MAINTENANCE

PRE-ACTIVATION CHECKLIST

ÎÎ To make sure that SAFEGATE has been congured correctly, follow the following checklist before

turning on the product for the rst time.

1. Verify that the electrical connections have been carried out correctly.

2. Verify that the supply voltage is 24Vdc ± 20% (PELV, compliant with EN 60204-1 (Chapter 6.4)).

3. Verify that access to the hazardous area can only take place through the gate protected by Safegate.

4. Verify that there are physical protection curtains preventing access to the hazardous area.

5. The power contactors operating the hazardous machine must meet the safety level o󰀨 the grid:
SIL 3 - PL and - Cat.4.

6. RESTART and OVERRIDE commands must not be accessible from inside the hazardous area.

7. The minimum safety distance must have been previously measured and respected during installation.

8. There must be no reective surfaces near the dangerous voyage.

9. Make sure that the MUTING/OVERRIDE signal lamp is installed in a visible location by the operator.

10. Ensure that there are no spurious light sources that may a󰀨ect the smooth operation of the SAFEGATE.

11. Make sure the on-board sta󰀨 has been adequately trained on the SAFEGATE operation.

PERIODIC CONTROL

Î Functional checks must be carried out at a certain frequency (e.g. daily), depending on the risk

analysis and the grid utilization environment.

1. Verify that Emitter and Receiver have been properly connected to the power supply. (24VDC±20%).

2. Verify (only if SAFEGATE is programmed via Software) that the blue LED “PRG” is turned on.

3. Verify the correct conguration settings:

a) MANUAL:

At power-up, the curtain waits for a RESTART command to activate its work cycle (START INTERLOCK).
Verify that this command is positioned so that it cannot be activated from the inside of the hazardous area.
Stop at least one beam of the protected area and make sure that the red LED on the Receiver
(RESTART INTERLOCK) lights up.

b) AUTOMATIC:

Stop at least one beam of the protected area and verify that the green LED
operation

4. Verify protected zone resolution: For the test, use the correct test object (matt cylinder of the diameter equal to
the resolution of the curtain. Refer to the Accessories/Spare Parts section for the correct ordering code for the
test object.

Controls, care and maintenance

a) Insert the test object into the controlled area and move it slowly from top to bottom (or vice versa), rst in

the centre, and then close to both the transmitter and the receiver.

b) For Multibeam models: Interrupt with one opaque object every one of the rst beams in the centre and then

close to both the Emitter and Receiver.

c) Check that at each stage of the test object movement the red LED on the receiver remains in any case

switched on and that the dangerous machine stops.

5. Verify of TEST function operation.

a) Referring to the chapter “CONNECTIONS”, activate the TEST function on the emitter and make sure that

the red LED

on the Receiver lights up.

CARE AND MAINTENANCE

SAFEGATE does not require any specic maintenance work; However, periodic cleaning of the frontal

protection surfaces of the two devices is recommended.
Cleaning should be carried out with a damp cloth; In particularly dusty environments, after cleaning the
front surface, it is advisable to spray it with an anti-static product.

Î In any case, do not use abrasive, corrosive, solvents or alcohol that may damage the part to be

wiped or wool cloth to avoid electrostatically loading the front surface of the curtain itself.

Î Even a very ne groove of frontal plastic surfaces can increase the width of the beam of the light

curtain, thus compromising the eectiveness of detection in the presence of reective lateral
surfaces.

Î It is therefore essential to pay particular attention during the cleaning steps of the curtain front

window, particularly in environments where abrasive powders are present. (e.g. cement plants, etc.).
