This symbol stands by a very important warning concerning the safety of persons.
Its non-observance can cause a very serious risk for the exposed personnel.
INTRODUCTION
The ADMIRAL AX BK photoelectric barrier is a multi-beam optoelectronic safety system. It
belongs to the family of Type 4 electrosensitive devices for the protection of personnel
exposed to risks arising from the use of hazardous machinery or plant, according to
standards IEC 61496-1,2 and EN 61496-1.
ADMIRAL AX BK is available in two different versions :
The ADMIRAL AX BK is a type 4 light curtain, consisting of an Emitter plus Receiver, that
integrates the floating blanking function.
The ADMIRAL AX BK is also available in a Master-Slave configuration.
A diagnostic display available on Emitter and Receiver provides the necessary information
for a correct use of the device and the evaluation of the possible operation defects.
ADMIRAL AX BK is ideal for the protection of :
Bending presses, presses, die cutting machines, punching machines, cutting and shearing
machines, assembly lines, palletization lines, etc.
If necessary, for any safety-related problems contact the competent safety
authorities or industrial associations in the country of use.
For applications in the food industry, please contact the manufacturer to ensure that
the barrier contains materials that are compatible with the chemical agents utilized.
The protective function of the optoelectronic devices is not effective in the following cases:
If the machine stopping control cannot be actuated electrically and it is not possible
to stop all dangerous machine movements immediately and at any time during the
operating cycle.
If the machine generates dangerous situations due to material being expelled or
falling from overhead.

8540581 - 29/09/2010 - Rev.10

OPERATION
If the protected area is clear, the two outputs on the Receiver are active and enable the
machine to which they are connected to operate normally.
Each time that an object bigger than or equal in size to the resolution of the system
intercepts the optical path of one or more beams, the Receiver deactivates the outputs.
This condition enables hazardous machine movements to be stopped (by means of an
adequate machine emergency stop circuit).
The resolution is the minimum dimensions that an object must have so that, on
crossing the protected area, it will certainly intercept at least one of the optical
beams generated by the barrier (Figure 1).
P = Pitch between two lenses
D = Diameter of one lens
R = Resolution = P+D
Figure 1
The resolution is constant irrespectively of work conditions, as it only depends on the
geometric characteristics of the lenses and the distance between the centres of two adjacent
lenses.
The height of the protected area is the height that is actually protected by the safety
barrier. If the latter is placed horizontally, this value refers to the depth of the protected area.
The working range is the maximum operative distance that can exist between the Emitter
and the Receiver.
ADMIRAL AX BK is available with the following resolutions:
– 14 mm, 20 mm (protected height from 150 mm to 1800 mm)
PROTECTION OF FINGERS
– 40 mm (protected height from 310 mm to 1800 mm)
PROTECTION OF HANDS
– 90 mm (protected height from 610 mm to 1800 mm)
PROTECTION OF BODY

INSTALLATION
Before installing the ADMIRAL AX BK safety system, make sure that:
The safety system is only used as a stopping device and not as a machine control
device.
The machine control can be actuated electrically.
All dangerous machine movements can be interrupted immediately. In particular, the
machine stopping times must be known and, if necessary, measured.
The machine does not generate dangerous situations due to materials projecting or
falling from overhead; if that is not the case, additional mechanical guards must be
installed.
The minimum dimensions of the object that must be intercepted are greater than or
equal to the resolution of the specific model.
Knowledge of the shape and dimensions of the dangerous area enables the width and height
of the relative access area to be calculated.
Compare these dimensions with the maximum working range and the height of the
protected area in relation to the specific model.
The general instructions set out below must be taken into consideration before placing the
safety device in position.
Make sure that the temperature of the environment in which the system is to be
installed is compatible with the temperature parameters contained in the technical
data sheet.
Do not install the Emitter and Receiver close to bright or high-intensity flashing light
sources.
Certain environmental conditions may affect the monitoring capacity of the
photoelectric devices. In order to assure correct operation of equipment in places
that may be subject to fog, rain, smoke or dust, the appropriate correction factors Cf
should be applied to the maximum working range values. In these cases:
where Pu and Pm are, respectively, the working and maximum range in meters.
Pu = Pm x Cf
4
8540581 - 29/09/2010 - Rev.10
Page 6
The recommended Cf factors are shown in the table below:
ENVIRONMENTAL CONDITION CORRECTION FACTOR Cf
Fog 0.25
Steam 0.50
Dust 0.50
Dense fumes 0.25
If the device is installed in places that are subject to sudden changes in temperature,
the appropriate precautions must be taken in order to prevent the formation of
condensation on the lenses, which could have an adverse effect on monitoring.
POSITION
The position of the AXE BK Emitter and the AXR BK Receiver must prevent access to the
danger zone from above, below and from the sides, unless at least one of the optical beams
has been intercepted. Some useful information regarding the correct position of the barrier is
shown in the figure below.

MASTER/SLAVE POSITIONING
In addition to the standard ADMIRAL models, ADMIRAL AX BK is available in the
MASTER/SLAVE configuration. Such configuration is made of two pairs of light curtains,
where the two emitters and the two receivers are respectively connected in series.
In master/slave models the blanking function is available only on the MASTER barrier.
The most common application is shown in Figure 3: the horizontal light curtain (A) has been
installed to detect the presence of a person between the vertical light curtain (B) and the
dangerous machine at system power-up or restart.

The length of the connection cable between the master and the slave can be up to 50 m.
This makes it possible to install two light curtains - one at the front and the other at the rear
of the machine – with just one connection to the power and control circuits of the machine.

SAFETY DISTANCE CALCULATION
The barrier must be installed at a distance that is greater than or equal to the minimum
safety distance S, so that a dangerous point can only be reached after all hazardous
machine movements have stopped (Figure 5).
According to European standard EN999, the minimum safety distance S must be calculated
using the following formula:
where:
S = K (t
+ t2) + C

The non-observance of the correct safety distance reduces or cancels the protective
action of the light curtain.
If the position of the barrier does not prevent the operator from having access to the
dangerous area without being detected, additional mechanical guards must be
installed to complete the system.

HORIZONTAL POSITION OF THE BARRIER
When the object’s direction of approach is parallel to
the floor of the protected area, the barrier must be
installed so that the distance between the outer limit
of the dangerous area and the most external optical
beam is greater than or equal to the minimum safety
distance S calculated as follows:
S = 1600(t1 + t2) + 1200 – 0.4H
where H is the height of the protected surface from
the base of the machine;
H = 15(D-50)
(D=resolution)
In this case, H must always be less than 1 meter.

AUTOMATIC FUNCTIONING
The ADMIRAL AX BK light curtain features only one Automatic operating mode (without restart interlock).
The ADMIRAL AX BK light curtain is not equipped with a start/restart interlock
circuit. This safety function is compulsory in most applications. The safety modules
of the AD SR series permit safe implementation of this function according to IEC
61496-1. Carefully assess the related risks analysis of own application.
In this functioning mode, the OSSD1 and OSSD2 safety outputs comply with the status of
the light curtain :
• with the area protected free, the outputs are active.
• with the area protected occupied, they are de-activated.
BLANKING FUNCTION
The ADMIRAL AX BK opto-electronic light curtain features a floating blanking function according to
which the user can inhibit the detection function from a minimum of 1 beam to a maximum of 3
adjacent beams with two different types of functioning according to the selected method of
configuration.
The blanking function is useful in applications in which, in specific safety conditions, opaque objects
must be introduced in the area protected by the light curtain without stopping the controlled machine.
This function is particularly useful when the area protected by the light curtain may be intercepted by
the material being processed or by a fixed or mobile part of the machine.
Î Note that this function cannot be activated on the synchronism beam (1
starting from the signalling label with display).
st
beam
Î Using the blanking function, the resolution of the light curtain is modified according
to Table 7 and Table 8.
When the width of the mobile object is less than that of the protected area (range),
suitable mechanical guards must be provided to the sides in order to prevent accidents
due to the unprotected areas . If the object is moved vertically, the safety guards must
move so that they remain adjacent with this. (Figure 10)

With this function, an object can be introduced in the dangerous area without de-activating the outputs
of the light curtain. The resolution is modified for the entire height of the protected area.
When the mobile object is removed, the outputs remain active. For this type of blanking, it is possible
to choose between three different methods of operation:
1. Mode A1: (Figure 11)
• With all the beams free, the protected area is free.
• With one beam occupied (except for the synchronism beam), the area is considered free.
• With two or more beams occupied, the area is considered occupied.

OBJECT
Curtain free Curtain occupied
Blanking With Object Presence Obligation (Mode B)
With this function, an object (mobile or fixed) can be maintained inside the danger zone without deactivation of the light curtain outputs.
The size of the introduced object must not be less than the initial resolution of the
light curtain or than the distance between the beams (in 90mm case). The object
must be inside the protected area during each phase of the process in which the
light curtain is active.
The width of the introduced object must be equal to that of the entire area protected by the light curtain
(range); if this condition is not complied with, the effective resolution obtained from Table 8 cannot be
considered valid inside and at the margins of the blanking area and a resolution corresponding to that
obtained with Mode A for a corresponding number of beams must be considered
(B1 is equivalent to A2 and B2 to A3).
If the object introduced has the above-mentioned characteristics, a resolution equal to the initial
resolution (without blanking) can be considered for the light curtain for the entire protected area except
at the margins of the blanking area where the effective resolution obtained from table 8 must be
considered.
This method of blanking is available with two configurations:
1. Mode B1: (Figure 14)
• With all the beams free, the mobile object is absent, therefore the outputs are de-
activated. The letter “b” is shown on the display of the receiver, indicating that the outputs
are de-activated due to absence of the mobile object.
• With one beam occupied (except for the synchronism beam), the mobile object is present
(blanking active and outputs ON).
• With two adjacent beams occupied (except for the synchronism beam), the area is
considered free (tolerance of 1 beam).
• With two or more non-adjacent beams occupied, the area is considered occupied.

MULTIPLE SYSTEMS
When more than one ADMIRAL AX BK system is used, precautions must be taken to avoid
optical interference between them: install the units so that the beam emitted by the Emitter of
one system can only be received by the relative Receiver.
Figure 23 illustrates some examples of correct positioning when two photoelectric systems
are installed. Incorrect positioning could generate interference, and may result in
malfunctioning.
Systems installed alongside each other:
Installation of two adjacent Emitters
Overlapping systems: B
L-shaped installation: C
Crossed positioning of Emitters and receivers
Figure 23
Î This operation is not necessary in case of coexistence of a MASTER
and a SLAVE.
8540581 - 29/09/2010 - Rev.10 25
Page 27
USE OF DEFLECTION MIRRORS
In order to protect or control areas that can be accessed from more than one side, in addition
to the Emitter and Receiver, one or more deflection mirrors can be installed.
These mirrors enable the optical beams generated by the Emitter to be deviated on one or
more sides.
If the beams emitted by the Emitter must be deviated by 90°, the perpendicular to the
surface of the mirror must form an angle of 45° with the direction of the beams.
The following figure illustrates an application in which two deviation mirrors are used to
provide a U-shaped protection.
Figure 24
The following rules should be taken into consideration when using deviation mirrors:
• Place the mirrors so as to ensure compliance with the minimum safety distance
S (Figure 24) on each side from which the danger zone can be accessed.
• The working distance (range) is given by the sum of the lengths of all the sides
that give access to the protected area. (Remember that for each mirror used
the maximum working range between the Emitter and the Receiver is
reduced by 15%).
• During installation, take great care to avoid twisting along the longitudinal axis
of the mirror.
• Make sure, by standing near to and on the axis of the Receiver, that the entire
outline of the Emitter is visible on the first mirror.
• The use of more than three deviation mirrors is not recommended.
26
8540581 - 29/09/2010 - Rev.10
Page 28
DISTANCE BETWEEN REFLECTING SURFACES
The presence of reflecting surfaces in proximity of the photoelectric barrier may generate
spurious reflections that prevent monitoring. With reference to Figure 25, object A is not
detected because surface S reflects the beam and closes the optical path between the
Emitter and Receiver. A minimum distance d must therefore be maintained between any
reflecting surfaces and the protected area. The minimum distance d must be calculated
according to the distance l between the Emitter and the Receiver, considering that the angle
of projection and reception is 4°.
Figure 25
Figure 26 illustrates the values for the minimum distance d that must be maintained when
the distance l between the Emitter and Receiver is changed.
Figure 26
After installing the system, check whether any reflecting surfaces intercept the beams, first in
the centre and then in the vicinity of the Emitter and Receiver. During these operations, the
red LED on the Receiver should never, for any reason switch off.
8540581 - 29/09/2010 - Rev.10 27
Page 29
MECHANICAL ASSEMBLY AND OPTICAL ALIGNMENT
The Emitter and the Receiver must be assembled opposite each other (at a distance
specified in the technical data sheet). Use the fastening brackets and inserts supplied with
the system to place the Emitter and the Receiver so that these are aligned and parallel to
each other and with the connectors facing the same way.
Depending on the dimensions and the shape of the support on which they are to be installed,
the Emitter and Receiver must be assembled with the fastening inserts at the back, or else
by fitting these in the side groove (Figure 27).
Perfect alignment of the Emitter and Receiver is essential in order to assure correct barrier
operation. The indicator LEDs on the Emitter and Receiver facilitate this operation.
Î To perform an easier alignment the use of SFB circular brackets is necessary.
These are available on request (ordering code 1330974).
Figure 27
• Position the optical axis of the first and last beam of the Emitter on the same
axis as that of the corresponding beams on the Receiver.
• Move the Emitter in order to find the area within which the green LED on the
Receiver stays on, then position the first beam of the Emitter (the one close to
the indicator LEDs) in the centre of this area.
• Using this beam as a pivot, effect small sideways movements of the opposite
end to move to the protected area clear condition. The green LED on the
Receiver will indicate this condition.
• Lock the Emitter and Receiver in place.
During these operations it may be useful to check the presence of the yellow LED weak signal
("d" letter for the slave m odel s) on the r ecei ver. Upon completion of alignment, this LED/letter
must be off.
Î In the case of MASTER/SLAVE models, first of all align the SLAVE pair and then
the MASTER pair.
Î If the Emitter and the Receiver are assembled in areas that are subject to strong
vibrations, the use of vibration-damping supports is necessary, in order to
prevent circuit malfunctions (code SAV-3 1200088, code SAV-4 1200089).

TEST FUNCTION
By means of the test function, which simulates occupation of the protected area, it
is possible to verify the operation of the entire system by means of an external supervisor
(e.g. PLC, control module, etc.).
The ADMIRAL AX BK 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. Please see table 3 (page 11) for details about the use of the test
function.
The minimum duration of the TEST function must be 40 msec.
OUTPUT STATUS
The ADMIRAL features two static PNP outputs on the Receiver, the status of which depends
on the condition of the protected area.
The maximum load allowed is 500mA at 24VDC, which corresponds to a resistive load of
48Ω. Maxim load capacity corresponds to 2µF. The meaning of the status of outputs is
defined in the table below. Any short circuit between outputs or between outputs and 24VDC
or 0VDC power supplies is detected by the barrier.

CHECKOUTS AND MAINTENANCE
Verification of barrier efficiency.
Before each work shift or before switching on, check the correct operation of the
photoelectric barrier.
Proceed as follows, intercepting the beams using the appropriate test object (available fr ee
of charge on request).
The correct test object must be used for testing, depending on the barrier resolution.
Please see page 38 for the correct ordering code.
Refer to Figure 32:
• Introduce the test object into the protected area and move it slowly, starting
from the top and moving down (or vice versa), first in the centre and then in the
vicinity of both the Emitter and the Receiver.
• Multibeam models:
Intercept each beam with an opaque object, first in the center of the detection
zone and then close to the emitter and the receiver.
• Make sure that during each stage of the test object’s movements the red LED
on the Receiver is always on.
The ADMIRAL AX BK barrier does not
require any specific maintenance
operations; however, periodic cleaning of
the front protective surfaces of the
Emitter and Receiver optics is
recommended.
Wipe using a clean, damp cloth; in
particularly dusty environments, after
cleaning the front surface, the use of an
anti-static spray is recommended.
Never use abrasive or corrosive
products, solvents or alcohol, which
could damage parts. Do not use woollen
cloths, that could electrify the front
Figure 32
surface.
34
8540581 - 29/09/2010 - Rev.10
Page 36
Grooving or fine scratching of the front plastic surfaces can increase the amplitude
of the emission angle of the light curtain, jeopardising detection efficiency in the
presence of lateral reflecting surfaces.
It is therefore fundamental to pay particular attention during the cleaning phases of
the curtain front window, especially in environments where abrasive dusts are
present. (E.g. cement factories, etc).
If the yellow LED weak signal ("d" letter for the slave models) on the receiver is on,
check that:
– the front surfaces are clean;
– the Emitter and Receiver are aligned correctly.
If the LED stays on, contact the REER service department.
