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 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 Active and Passive elements 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.

System architecture
SYSTEM ARCHITECTURE
SAFEGATE is supplied as a pair (Active and Passive element) and allows integration with external Muting
sensors that are directly connected to the connectors installed on the curtain.
¾Each curtain can be congured as LX, L2, TX and T4 (see the di󰀨erent Muting types in the section
“MUTING FUNCTION”) through the wiring of the main connector. This conguration can be changed
at any time.
¾SAFEGATE can be used with (pre-aligned and pre-congured) Muting arms, with M TRX photocells
(available as accessories) or any other Muting sensor.
¾S-A models provide Automatic operation (without “START/RESTART INTERLOCK”, “EDM”
and Muting function).
¾Smodels integrate the functions of “START/RESTART INTERLOCK” and “EDM” but do not allow the
Muting function.
¾SM models allow the Muting function, but have no integrated signal lamp.
¾Programmable SMP-SMPO models allow an ideal use of further conguration options to solve potential
problems in complex application scenarios.
¾SMO-SMPO models with Integrated signalling lamp allow the immediate viewing of the curtain status
even at a distance.

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.
ÎÎCarefully 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:
ÎÎIEC TS 62046 - “Application of protection devices for people
detection”.
ÎÎEN 415-4 - “Safety on packaging machines – Palletizers and
Unpalletizers”.
ÎÎIEC 61496-1 - “Electro-sensitive protective devices”.
Î General requirements about safety:
¾The Muting function is a temporary suspension of the safety function that needs to be activated and
deactivated automatically.
¾The 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.
¾It should not be possible to activate the Muting function when SAFEGATE has deactivated the safety
outputs.
¾It should not be possible to start a Muting function by switching o󰀨 and then restarting the device.
¾Muting must be activated at an appropriate point of the machine cycle, i.e. only when there are no risks
for the operator.
¾Muting sensors must be mechanically protected so that any impact does not modify their alignment.
¾If the distance between the muting sensors is lower than required, the SAFEGATE safety function is
not guaranteed.
¾Make sure that the MUTING/OVERRIDE signal lamp is correctly installed in a visible location by the
operator.

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.
ÎÎOther 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.

The Muting function
B) 2 INTEGRATED PARALLEL MUTING SENSORS, ONLY FOR PALLET OUTPUTS (L2)
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 max 4 sec) of
sensors S1 and S2. 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.
ÎÎOther timings are available with programmable programs.
Î For the safe operation of the L2 conguration, it is imperative that horizontal Muting sensors are
located within the hazardous area.
Î The minimum distance between two consecutive pallets must be greater than 40 cm.

The Muting function
C) 2 INTEGRATED CROSS MUTING SENSORS, FOR BI-DIRECTIONAL GATES (TX)
In this way, the two Muting sensors are each rst on a di󰀨erent side of the vertical curtain.
This mode is unidirectional and is useful for protecting gates with pallet output.
ÎÎThe crossing point of the two Muting sensors must be placed inside the hazardous area to avoid
undesirable and dangerous activations of the Muting function.
The activation of the Muting function occurs after the simultaneous interruption (within max 4 sec) of
sensors S1 and S2. As long as both sensors remain busy, the Muting function continues. By releasing the
rst of the two sensors, the Muting function is disabled.
This mode also allows selecting the maximum duration of the Muting condition (timeout) as 30 seconds or
9 hours.
ÎÎOther timings are available with programmable programs.

The Muting function
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).
ÎÎFor 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 opposite direction).
ÎÎFor the T4 models (sequential operation), there are two available timeouts: 1) 30 sec; 2) innite.
ÎÎOther timings are available with programmable programs.
ÎÎIn both modes of operation, the minimum pallet length must be 70 cm (to ensure simultaneous
occupancy of all four sensors).

The Muting function
E) 2 EXTERNAL CROSS INTEGRATED MUTING SENSORS, FOR BI-DIRECTIONAL GATES (TX).
This mode is bidirectional and is useful for protecting gates with pallet output.
ÎÎThe crossing point of the two Muting sensors must be placed inside the hazardous area to avoid
undesirable and dangerous activations of the Muting function.
The activation of the Muting function occurs after the simultaneous interruption (within max 4 sec) of
sensors S1 and S2. As long as both sensors remain busy, the Muting function continues. When the rst
of the two sensors is released, the Muting function is disabled. In this mode of operation the maximum
duration of the Muting condition (timeout) can be selected in 30 seconds or 9 hours.
ÎÎOther timings are available with programmable programs.
