GENERAL OBSERVATIONS
The ARGOLUX AS curtain is a multibeam optoelectronic protective device
designed to secure operators working on dangerous machines in an
industrial environment.
The ARGOLUX AS system is made up of an emitter, a receiver and a
separatecontrolunit.The3unitsarecombinedtoprovideatype2fail-safe
system as defined by the EN 61496-1 and prEN 61496-2 («Safety of
machinery - Electro-sensitive protective system»).
When an opaque object (such as the operator’s hand or arm) enters the
dangerous areas and therefore goes through the detection field between
the emitter and the receiver, the control unit de-energizes its output relays.
The result is the immediate stoppage of the dangerous movement if the
control unit is correctly connectedto the machine control circuitry.
To fulfil correctly its safety function, the safety system must be correctly
interfaced to the machine circuitry and correctly positioned regarding the
danger zone to reduce or cancel risk.

APPLICATIONS
The ARGOLUX AS curtain may be used on industrial machines for which
the risk assessment allows the use of a type 2 electrosensitive protective
system.

The following are examples of machines where the ARGOLUX AS may be
used:
•Machinery for product handling such as conveyors, palletizing,
collating machines;
•Packaging and wrapping devices;
•Automated assembly lines;
•Automated warehousing.
To control access all around a machine, the ARGOLUX AS curtain can be
usedwithdeflectionmirrorstobuildaperimetricprotectionsurroundingthe

TEST SEQUENCE AND CONTROLS

Optical scanning circuitry.
Optical scanning circuitry.Optical scanning circuitry.
Optical scanning circuitry.
The scanning circuitry of ARGOLUX AS safety barrier is based upon a
self-checking principle which permanently controls its correct operation.
Particularly,thesystemcontrolsthemultiplexsignalontheemitterside,and
measures theIR light pulse period emitted foreach beam of the curtain.
The reversed operations are carried out on the receiver side where the
system controls the demultiplex signals and recognize the infrared light
pulse thanks to the measurement of the caught light period.
An accurate synchronisation enables this identification and avoids taking
into account possible infrared disturbances.
If an unwanted condition occurs during the IR light beam transmission (an
object is in the detection field or a failure appears), the receiver sends a
command signal to the control unit which de-energizes its relays and
remains in the alarm condition until the fault condition is removed.
Output circuitry.
Output circuitry.Output circuitry.
Output circuitry.
The control unit AU S3 controls the correct operation of the both emitter
and the receiver units thanks to its electrical connection with the receiver
ASR. The receiver provides thecontrol unitwith a signal through its unique
relay output. As mentioned in the EN 61496-1 norm, the test facility
provided with type 2 optoelectronic protective devices is partly designed to
checkthe correct operation ofthis relayoutput.
Other operations are checked during the test to ensure the integrity of the
system:
•The correct interlinking of the test sequence and the effective reset
of the system (test command);
•The reaction time of the two inner relays A and B (safety relays with
guided contacts) and the reaction time of the two external relays
K1 and K2, if auxiliary contacts of K1 and K2 are connected to
terminals 5 and 6 (use only safety relays with guided contacts);
•The inner command of A and B relays. A possible failure of one
component of the output circuitry can only be detected during the
test phase, and therefore the control unit de-energizes its relays
only when the next test is applied. This is also true for external
relays K1 and K2 by means of the feedback control (see below).

The control unit displays a test input whichmust be used to generate a test
sequence before each reset of the safety system or before a machine cycle
if necessary.
European regulations enforce the test performance before the effective
reset of the system, at power up and after any intrusion into the detection
field.
The test command is activated by closing a contact between terminals 15
and 16 during 10ms at least. The test is then performed during 100ms.
Ifafailureis detected,theresetofthesystemis impossibleandnomachine
cycle can be initiated. If no a failure is detected, the control unit energizes
its relays A and B, which is the condition to initiate a new machine cycle.

The first step consists in controlling the correct operation of the scanning
circuitry.
The system checks that the ASR receiver output relay goes to the OFF state

Then, the next step consists in controlling the AU S3 output relay . The ON
and OFF reactiontimes of both relays are measured and compared.
During the100ms testperiod, the outputs remainopen(contactsbetween

When the test needs to be generated by the operator himself using a
pushbutton, the following applies:
•The pushbutton should be fixed outside the dangerous area;
•The pushbutton must be installed at a point that gives the operator
the best visibility of the dangerous zone.
Before installing the ARGOLUX AS safety barrier, the following must be
checked:
•The moving part of the machine can be electrically controlled;
•It is possible to stop immediately anydangerous movement of the
machine. Stopping time of the machine must be known;
•The machine cannot create dangerous situations related to the
falling or the ejection of objects. If this is the case, additional
mechanical guards must be installed;
•The minimum size of the detected object must be greater or equal
to the selected model resolution.

Before installing the safety barrier, the following conditions should be
observed:
•Ambient temperature should be compatible with the specified
operating temperature.
•The emitterandthereceiver should be protected against excessive
light source intensity (greater than the specified ambient light
immunity).
•Fog, rain, smoke or dust may influence optoelectronic devices.
Therefore, we recommend to apply a correction value Fc to the
specified nominal scanning range in order to guarantee a correct
operation of the system:
Pu = Pm x Fc
Pu = Pm x FcPu = Pm x Fc
Pu = Pm x Fc
Pu: maximum scanning range in meters.
Pm: nominal scanning range in meters for a clear environment.
The following table shows the recommended correction values.
•If sudden temperature variations are foreseen, proper measures
should be taken to avoid condensation accumulation on lens.
Excessive accumulation could generated unexpected alarm.
