This symbol indicates an important personal safety warning. Failure to
comply with the warning may result in very high risk for exposed personnel.
INTRODUCTION
The ReeR control unit is a safety device complying with
IEC 61496-1, IEC 61496-2 specifications. When connected to a Ilion or
a ULISSE/ILION UPC safety photocell, it forms a type 2 ESPE (Electrosensitive Protective Equipment).
Possible connections: from 1 to 4 photocells
Restart manual or automatic selectable
2 N.O. outputs with guided contact safety relays
1 system monitor PNP output
1 external contactors feedback input
Connected safety photocells periodic autotest (every 5s) .
Possible connections: from 1 to 4 photocells
Manual or automatic selectable Restart

1 muting lamp output
Muting Override function integrated
Selectable muting timeout
Connected safety photocells periodic autotest (every 5s).
The control unit also guarantees that:
the output lines are open if the photocell is intercepted;
the output lines are enabled only with correct response
times;
in manual mode, maintenance of the RESTART contact
closed is not interpreted as AUTO mode.
For safe use of the device, it is essential to read and understand the contents
of this handbook.
Failure to comply with the prescriptions indicated in this handbook may result
in very high risks for the operating personnel of the machine protected.
Carefully consider the risks analysis of the application and the
legislation of the barrier application Country to establish if the
application is compatible with the safety category 2.
CONTROL UNIT SERIES AUS X

NEW SAFETY PARAMETERS FOR TYPE 2 BARRIERS AND
MANDATORY LABELLING
With the publication of Edition 3 of the harmonized EN 61496-1
standard it is no longer possible to use a Type 2 safety light barrier
for safety functions assessed as SIL 2 / PL d.
If a safety level of SIL 2 / PL d (or higher) is required and it is
nevertheless intended to use a safety light barrier, then it will be
necessary to use a Type 4 safety light barrier.
This regulatory requirement derives from the fact that the reduction of
risk that can be obtained via a photoelectric safety barrier is not only
a function of the safety level of its electronic parts, but is also
determined by its systematic capabilities (for example:
environmental influences, EMC, optical performance and detection
principle).
The systematic capability of a Type 2 photoelectric barrier may in fact
not be sufficient to ensure adequate risk reduction for SIL 2 / PL d
applications.
The standard also establishes that the labelling of Type 2 safety
barriers must indicate such limitation to SIL 1 / PL c.
The PFHd values declared for the electronic control part of the
device, on the other hand, are not limited and therefore it is possible
to use the PFHd value provided by the manufacturer of the device in
the global assessment of the safety function, even if it exceeds the
SIL 1 / PLc range.

In this operating mode, the outputs of the control unit follow the
status of the photocell:
• with the protected area free (outputs of the photocells active), the
relay outputs of the control unit are active.
• with the protected area occupied (outputs of the photocells de-
activated), the relay outputs of the control unit are de-activated.
Figure 1
Use in manual mode (start/restart interlock activated) is mandatory in the
case in which the safety device controls an access protecting a danger zone
and once a person has passed through the opening, he/she may remain in
the danger zone without being detected (use as trip device according to
IEC 61496). Failure to comply with this rule may result in very serious risks
for the persons exposed.
Check correct functioning of the entire safety system (control unit+photocell)
following each re-installation. In particular, if the original operating mode was
Manual, check that the unit has been reconfigured in this mode.

MANUAL
In this operating mode, the outputs of the control unit are activated
only if the protected area is free and after sending the RESTART signal
to the control unit using the push-button or by means of a specific
command on the RESTART input (terminal 4).
Once the protected area has been occupied, the relay outputs are deactivated. The sequence described above must be repeated in order to
re-activate them.
The RESTART command is active with a 0VDC ---> +24VDC transition.
The minimum duration of the command is 100 ms.

Table 2
The RESTART command
The RESTART command must be sent to the control unit
connecting terminal 4 to the +24Vdc.
The contact used for the RESTART command must be able
to switch a voltage of 24Vdc and a current of 20mA
(guaranteeing a closing time > 100ms). This data is
particularly important in the case of automatic
management of the RESTART command sending, for
example using a PLC.
The SYSTEM RESET TIME is obtained adding the reset time
of any external contactors K1K2 to the reset time of the
AUS X control unit (100ms).
In the case of manual activation, a normally open external
button can be used, temporary closing of which generates
the RESTART command.
The Restart control must be installed outside the danger area in a position
where the danger area and the entire work area concerned are clearly visible.
It must not be possible to reach the control from inside the danger area.
CONTROL UNIT SERIES AUS X
8540643 - 26/08/2016 Rev.13 11
The SYSTEM_TEST command
The SYSTEM_TEST command must be forwarded to the control unit
connecting the terminal 6 to the +24Vdc.
The contact used for the SYSTEM_TEST command must be able to
switch a current of 20mA and a voltage of 24Vdc (with a switching time
of >40ms). The AUS X control unit, after receiving this signal, provides
to switch off the emitters of the connected safety photocells,
The operator must verify the effective stopping of the hazardous
machine (due to the de-activation of the control unit outputs) for all the
time the SYSTEM_TEST command stays active.
The effective stopping of the system must be verified by an operator and
cannot be an operation of the control unit.
K1K2 FEEDBACK input
Using the K1 and K2 auxiliary safety contactors with guided contact
safety type, it is necessary to connect the +24Vdc to the
through the series of the K1-1 e K2-1 N.C. control
contacts. The control of the correct switching of K1 and K2 is
performed with a delay of 300ms after the real command.
When the K1-1 e K2-1 N.C. control contacts are not used (or no control
is provided) it is mandatory to connect the terminal 11 (
) to the terminal 12 ( ).
SYSTEM STATUS output
The SYSTEM STATUS output reports exactly the output safety relays status :
When the output relays are opened, the SYSTEM STATUS reports 0VDC.
When the output relays are closed, the SYSTEM STATUS reports
+24VDC.
INSTALLATION AND ELECTRICAL CONNECTIONS
Install the AUS X control unit in an environment with a protection rating of at
least IP54.
If more modules AUS X must be installed in the same board panel, in order to
avoid overheatings, maintain between them one minimal distance of 2cm.
The AUS X control unit must be supplied with a 24Vdc 20.
The external power supply must comply with the standard EN 60204-1.
During the installation of the AUS X control unit be sure to avoid short circuits
between the contacts 7 and 8.
CONTROL UNIT SERIES AUS X
12 8540643 - 26/08/2016 Rev.13
Characteristics of the output circuit.
For the output circuit, the control unit uses two guided contact safety
relays.
These relays are rated by the manufacturer for voltage and current
values above those indicated in the technical data; however, to assure
correct insulation and to avoid damage or premature aging, protect
each output line with a 4A slow-blow fuse and check that load
characteristics comply with the indications given in the table below.
Minimum switching voltage
18 Vdc
Minimum switching current
20 mA
Maximum switching voltage
250Vac
Maximum switching current
2A
Use of K1 and K2 auxiliary contact elements.
For loads with higher voltage and current characteristics than those
indicated in the table above, use of auxiliary external relays or
contactors suitable for the load to be controlled is recommended.
The K1 and K2 auxiliary contactors or relays must be of the guided
contact safety type.
Referring to the table below, pay particular attention to the
configuration of the control contacts on terminal 11 and that of the
contacts of use.
Control contacts
K1-1 normally closed
K2-1 normally closed
Use contacts
K1-2 normally open
K2-2 normally open
Control contacts K1-1 and K2-1 (terminal 11) must be able to switch
a current of 20mA and a voltage of 24Vdc.
To increase the electrical life of internal relays A and B, it is
advisable to use anti-disturbance devices which must be connected
across the coils of K1 and K2.
Warnings regarding the connection cables.
For light curtain/control unit connections of more than 50m, cables
with a cross-section of at least 1mm2 must be used.
It is good practice to separate the power supply of the control unit
from that of other electrical appliances (electrical motors, inverters,
frequency variators) or other sources of disturbance.
The path of the connection cables between the control unit ands
the sensors, the connection referring to the test command and
feedback contacts connected to terminal 11 must be different from
that of other power cables.

MUTING FUNCTION
The Muting function is a temporary suspension of the safety light curtain’s
protective function. Carefully check your risk analysis in order to assess
whether the Muting function is compatible with your application and what
additional measures have to be taken.
The Muting function generates a temporary, automatic interruption of
the protective function in order to permit normal transit of material
through the guarded opening.
The Muting function is activated when the system detects the object
that interrupts the opening protected. In other words, when the system
recognizes the material and distinguishes between this and any
operator (in a potentially dangerous situation), it is enabled to bypass
the light curtain temporarily, allowing the material to pass through the
opening.
CONTROL UNIT SERIES AUS X
8540643 - 26/08/2016 Rev.13 25
The Muting sensors form the sensing system that decides whether the
Muting function is to be activated (or not). Control of the dangerous
opening can be de-activated only by a correct sequence of interruption
of the beams of the Muting sensors.
Figure 17
Muting with AUS XM on palletizing system application example
Muting sequence
The timing diagrams in Figure 18 and Figure 19 show the correct
signal sequence. The muting function is initiated by the contemporary
occurrence of two events :
When the two beams of the muting sensors are activated within a
time limit of 4 sec.
When the muting enable signal (terminal 11) is high (+24Vdc)
The muting function is terminated by one of the following events:
As soon as one of the muting sensors is no longer activated
whichever occurs first.
When the muting time-out limit is expired; in this case the OSSDs
are brought to the off-state. The muting time-out limit can be
selected at 30sec or .
The muting enable command will only enable the muting function and should
be generated at the appropriate time by the machine control system(e.g.
When the muting function is needed); it has no effect on the deactivation of
the muting function. If not used, fix the terminal 11 at +24Vdc.
This means that a time limit is always mandatory. If a time
out limit of 30 sec is a too short time for a particular machine cycle, the
configuration without time monitoring (t = ) can be selected. In this case
alternative solutions or additional measures shall be implemented
or by the muting sensors activated all the time.
For example for the application of guarding the openings of a conveyor
system (palletizers) by monitoring appropriate signals generated by the
transport system to determinate if and when a pallet is in the detection zone.

MUTING OVERRIDE FUNCTION
The OVERRIDE function must be used when the machine stops due to
incorrect Muting activation sequences with the material obstructing the
guarded opening.
In this situation, the OSSD outputs are not active as the photocell
and/or at least one Muting sensor is occupied. In this condition the
OVERRIDE request led blinks (ref. "Status Indicators").

This function activates the OSSD outputs making it possible to remove the
material that is obstructing the protected field.
Throughout the entire phase during which the OVERRIDE function is active,
the Override/Muting light blinks. Check efficiency of this light periodically
(during the Muting or Override phases).
Warning!! The Override with pulse command automatically activates the
outputs of the photocell until both the photocell and the muting sensors are
free of obstacles again. During this period, the photocell is unable to protect
access to the guarded opening. Therefore, all operations must be carried out
under the strict supervision of expert personnel.
During the installation of the AUS XM control unit be sure to avoid short
circuits between the contacts 7 and 8.
The operator will use the Override mode previously selected.

The RESTART command
The RESTART command must be sent to the control unit
connecting terminal 15 to the +24Vdc.
The contact used for the RESTART command must be able
to switch a voltage of 24Vdc and a current of 20mA
(guaranteeing a closing time > 100ms). This data is
particularly important in the case of automatic
management of sending of the RESTART command, for
example using a PLC.
The SYSTEM RESET TIME is obtained adding the reset time
of any external contactors K1K2 to the reset time of the
AUS XM control unit (100ms).
In the case of manual activation, a normally open external
button can be used, temporary closing of which generates
the RESTART command.
The Restart command must be installed outside the danger area in a position
where the danger area and the entire work area concerned are clearly visible.
It must not be possible to reach the control from inside the danger area.
The SYSTEM_TEST command
The SYSTEM_TEST command must be forwarded to the control unit
connecting the terminal 16 to the +24Vdc.
The contact used for the SYSTEM_TEST command must be able to
switch a current of 20mA and a voltage of 24Vdc (with a switching time
of > 40ms). The AUS X control unit, after receiving this signal, provides
to switch off the emitters of the connected safety photocells,
The operator must verify the effective stopping of the hazardous
machine (due to the de-activation of the control unit outputs) for all the
time the SYSTEM_TEST command stays active.
The effective stopping of the system must be verified by an operator and
cannot be an operation of the control unit.

K1K2 FEEDBACK input
Using the K1 and K2 auxiliary safety contactors with guided contact
safety type, it is necessary to connect the +24Vdc to the
through the series of the K1-1 e K2-1 N.O. control
contacts. The control of the correct switching of K1 and K2 is
performed with a delay of 300ms after the real command.
When the K1-1 e K2-1 N.O. control contacts are not used (or no control
is provided) it is mandatory to connect the terminal 20
( ) to the terminal 21 ( ).
SYSTEM STATUS output
The SYSTEM STATUS output reports exactly the output safety relays status :
When the output relays are opened, the SYSTEM STATUS reports 0VDC.
When the output relays are closed, the SYSTEM STATUS reports
+24VDC.
INSTALLATION AND ELECTRICAL CONNECTIONS
Install the AUS XM control unit in an environment with a protection rating of
at least IP54.
If more modules AUS XM must be installed in the same board panel, in order
to avoid overheatings, maintain between them one minimal distance of 2cm.
The AUS XM control unit must be supplied with a 24Vdc 20.
The external power supply must comply with the standard EN 60204-1.
During the installation of the AUS XM control unit be sure to avoid short
circuits between the contacts 17 and 18.
Characteristics of the output circuit.
For the output circuit, the control unit uses two guided contact safety
relays.
These relays are rated by the manufacturer for voltage and current
values above those indicated in the technical data; however, to assure
correct insulation and to avoid damage or premature aging, protect
each output line with a 4A slow-blow fuse and check that load
characteristics comply with the indications given in the table below.

CONTROL UNIT SERIES AUS X
8540643 - 26/08/2016 Rev.13 31
Use of K1 and K2 auxiliary contact elements.
For loads with higher voltage and current characteristics than those
indicated in the table above, use of auxiliary external relays or
contactors suitable for the load to be controlled is recommended.
The K1 and K2 auxiliary contactors or relays must be of the guided
contact safety type.
Referring to the table below, pay particular attention to the
configuration of the control contacts on terminal 20 and that of the
contacts of use.
Control contacts
K1-1 normally closed
K2-1 normally closed
Use contacts
K1-2 normally open
K2-2 normally open
Control contacts K1-1 and K2-1 (terminal 20) must be able to switch
a current of 20mA and a voltage of 24Vdc.
To increase the electrical life of internal relays A and B, it is
advisable to use anti-disturbance devices which must be connected
across the coils of K1 and K2.
Warnings regarding the connection cables.
For light curtain/control unit connections of more than 50m, cables
with a cross-section of at least 1mm2 must be used.
It is good practice to separate the power supply of the control unit
from that of other electrical appliances (electrical motors, inverters,
frequency variators) or other sources of disturbance.
The path of the connection cables between the control unit ands
the sensors, the connection referring to the test command and
feedback contacts connected to terminal 20 must be different from
that of other power cables.
