3Product description
This chapter provides information on the operation of the safety light curtain and shows
examples of its range of use.
3.1Structure and function
The deTec2 Core safety light curtain is an electro-sensitive protective device (ESPE)
consisting of a sender and receiver.
A series of parallel infrared light beams form a protective field between sender and re‐
ceiver that protects the hazardous area (hazardous point, access and hazardous area
protection). When one or more beams are completely interrupted, the safety light cur‐
tain reports the interruption in the light path to the secure output signal switching devi‐
ces (OSSDs) by a signal change. The signal to stop the dangerous state of the machine
must be evaluated by a safe control or safety relay (contactors).
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required.
Figure 1: Sender and receiver
Protective field height The protective field height indicates the range within which the test rod belonging to
the safety light curtain is detected. The size of the safety light curtain determines the
protective field height. The design and construction of the safety light curtain deTec2
Core extends the protective function of a device to the end of the housing without any
blind spots.

Interrelationship: Reso‐
lution and scanning
range
The deTec2 Core safety light curtain is available with a protective field height of 300
mm to 2100 mm (150 mm steps). The available resolution versions are 14 mm (0 - 7
m scanning range) and 30 mm (0 - 10 m scanning range).
The scanning range is reduced by using deflector mirrors and/or a weld spark guard.
Additional information: see "Deflector mirror", Page 56 and "Weld spark guard",
Page 55.
3.2Product characteristics
3.2.1Absence of blind zones
The design and construction of the safety light curtain extends the protective function
of a device to the end of the housing without any blind spots. The absence of blind

DANGER
Risk of ineffectiveness of the protective device
Persons and parts of the body to be protected are not recognized in case of non-ob‐
servance.
Make sure that the following design requirements are met such that the safety light
b
curtain can fulfill its protective function.
– Sender and receiver must be arranged such that persons or parts of the body are
reliably detected when they enter the hazardous area.
– Reaching under, over and around as well as moving the safety light curtain must be
prevented.
– If people can stop between the protective device and the hazardous point without
being detected, check if additional protective measures (e. g. restart interlock with a
reset button) are required.
4.3.1Scanning range and protective field width
Scanning range The scanning range limits the maximum protective field width. The protective field
width cannot change during operation see "Technical data", Page 47.
The scanning range, see "Deflector mirror", Page 56 and "Weld spark guard",
Page 55 is reduced by using deflector mirrors and/or a weld spark guard.
Protective field range The protective field range is the dimension of the light path between sender and receiv‐
er. It is automatically calibrated with switching on the safety light curtain during initiali‐
zation and must not be changed during operation.
DANGER
Risk of ineffectiveness of the protective device
Persons and parts of the body to be protected are not recognized in case of non-ob‐
servance.
The safety light curtain can only be mounted to machines on which the protective
b
field width does not change when the safety light curtain is switched on.
4.3.2Minimum distance from the hazardous point
A minimum distance must be maintained between the safety light curtain and the haz‐
ardous point. This distance is required to prevent a person or part of the body from
reaching the hazardous area before the dangerous state of the machine state has com‐
pleted.
DANGER
Risk of ineffectiveness of the protective device
The dangerous state of the machine is not stopped or not stopped in a timely manner
for non-compliance.

The calculation of the minimum distance is based on international and national stand‐
ards and statutory requirements applicable at the place of installation of the machine.
If the minimum distance is calculated according to ISO 13855, then it depends on the
following points:
Subject to change without notice
PROJECT PLANNING
– Machine stopping time (time interval between triggering the sensor function and the
end of the dangerous state of the machine)
– Response time of the protective device see "Response time", Page 49
– Reach or approach speed of the person
– Resolution (detection capability) of the safety light curtain
– Type of approach: orthogonal or parallel
– Parameters specified based on the application
For the USA (scope of OSHA and ANSI), the following regulations apply among others:
a) Laws: Code of Federal Regulations, Title 29 (CFR29) Part 1910.217
b) Standards: ANSI B11.19
NOTE
Additional information is available in the ISO 13855 standard and in the Guidelines

Figure 7: Minimum distance to hazardous point for orthogonal approach to protective field
Calculation example of the minimum distance S according to ISO 13855
The example shows the calculation of the minimum distance for orthogonal approach
to the protective field. Depending on the application and the ambient conditions (e.g. a
protective field parallel or at an arbitrary angle to the direction of approach or an indi‐
rect approach), a different calculation may be required.
– First, calculate S using the following formula:
S = 2000 × T + 8 × (d – 14) [mm]
where
O PE R AT I NG IN S TR U CT I ON S | deTec2 Core
17
4 PROJECT PLANNING
– T = machine stopping time + response time of the protective device after interrup‐
tion in the light path [s]
– d = resolution of the safety light curtain [mm]
– S = minimum distance [mm]
The reach/approach speed is already included in the formula.
– If the result S ≤ is 500 mm, then use the determined value as the minimum dis‐
tance.
– If the result S is > 500 mm, then recalculate S as follows:
S = 1600 × T + 8 × (d – 14) [mm]
– If the new value S is > 500 mm, then use the newly determined value as the mini‐
mum distance.
– If the new value S is ≤ 500 mm, then use 500 mm as the minimum distance.
Example calculation Machine stopping time = 290 ms
Response time after interruption of the light path = 30 ms
Resolution of the safety light curtain = 14 mm
T = 290 ms + 30 ms = 320 ms = 0.32 s
S = 2000 × 0.32 + 8 × (14 – 14) = 640 mm
S > 500 mm, therefore:
S = 1600 × 0,32 + 8 × (14 – 14) = 512 mm
Taking reaching over in‐
to account
If access to the hazardous area cannot be ruled out by reaching over a vertical protec‐
tive field, the height of the protective field and minimum distance of the ESPE must be
determined. This is done by comparing the calculated values based on the possible de‐
tection of limbs or body parts with the values resulting from reaching over the protec‐
tive field. The greater value resulting from this comparison must be used. This compari‐
son is to be carried out according to ISO 13855, Section 6.5 or national regulations.

cannot be reached over. Right: Protective field that can be reached over.
4.3.3Minimum distance to reflective surfaces
18
DANGER
Risk of ineffectiveness of the protective device
Reflective surfaces and dispersive media can prevent persons or parts of the body to
be protected from being properly reflected and therefore, remain undetected.
Make sure that all reflective surfaces and objects maintain a minimum distance
b
from the protective field.
Make sure that no dispersive media is found within the calculated minimum dis‐
b
tance from the protective field.
O PE R AT I NG IN S TR U CT I ON S | deTec2 Core8014276/2014-02-18 | SICK
The light beams from the sender may be deflected by reflective surfaces and dispersive
media. This can result in non-detection of an object.
Therefore, all reflective surfaces and objects (e.g. material bins, machine table, etc.)
must maintain a minimum distance (a) from the protective field. This minimum dis‐
tance (a) must be maintained on all sides of the protective field. This applies in horizon‐
tal, vertical and diagonal directions as well as at the end of the safety light curtain.
Make sure that no dispersive media is found within the calculated minimum distance
from the protective field.
The minimum distance (a) depends on the distance (D) between sender and receiver
(protective field width).

How to determine the minimum distance from reflective surfaces:
Determine the distance D [m], sender – receiver.

4.3.4Protection against interference from systems in close proximity to each other
The infrared light beams of the sender of system 1 can interfere with the receiver of
system 2. This can disrupt the protective function of system 2. This would mean that
the operator is at risk. Avoid such installation situations or take appropriate action, e.g.
install optically opaque partitions or reverse the direction of transmission of a system.
Figure 11: The direction of transmission of systems in close proximity to each other is reversed.
The sender of the 2nd system is not affected by the beams 1st system.

4.4Integration in electrical control
This chapter contains important information about integration in the electrical control.
Information about the individual steps for electrical installation of the device: see "Elec‐
trical installation", Page 33.
Requirements for use Depending on the safety concept, the signal to stop the dangerous state of the ma‐
chine must be evaluated by a safe control or safety relay (external control).
DANGER
Risk of ineffectiveness of the protective device
Persons and parts of the body to be protected are not recognized in case of non-ob‐
servance.
Make sure that the following control and electrical requirements are met such that
b
the safety light curtain can fulfill its protective function.
– The control of the machine must allow electrical interference.
– The electrical control of the machine must meet the requirements of IEC 60204-1.
– A restart interlock must be implemented depending on applicable national regula‐
tions or required reliability of the safety function. Because the safety light curtain
does not have this function, it must be implemented in the external control if re‐
quired.
– When using a safe control, different signal levels of both OSSDs must be detected
depending on applicable national regulations or required reliability of the safety
function. The maximum time tolerated by the control during which the OSSDs may
exhibit different states must be selected according to the application.
– The OSSD1 and OSSD2 output signals must not be connected to each other.
– In the machine controller, the signals of both OSSDs must be processed separately.

– The machine must switch to the safe state at any time if at least one of the two
OSSDs switches to the LOW state.
– Prevent the formation of a potential difference between the load and the protective
device. If you connect loads to the OSSDs (safety outputs) that then also switch if
controlled with negative voltage (e.g. electro-mechanical contactor without reverse
polarity protection diode), you must connect the 0 V connections of these loads and
those of the corresponding protective device individually and directly to the same 0
V terminal strip. In the event of a fault, this is the only way to ensure that there can
be no potential difference between the 0 V connections of the loads and those of the
corresponding protective device.

– When using external switching elements (e.g. positively guided contactors), verifica‐
tion of the external switching elements (external device monitoring) must be imple‐
mented depending on applicable national regulations or required reliability of the

Requirements for the
electrical control of the
machine
The two outputs are protected against short-circuits to 24 V DC and 0 V. When the pro‐
tective field is clear, the signal level on the outputs is HIGH (at potential) and when the
light beams are interrupted or there is a device fault the outputs are LOW (over 1.5 kΩ
towards 0 V).
The safety light curtain complies with the rules for electromagnetic compatibility (EMC)
for the industrial sector (Radio Safety Class A). Radio interference cannot be ruled out
when used in residential areas.
DANGER
Risk of ineffectiveness of the protective device
Persons and parts of the body to be protected are not recognized in case of non-ob‐
servance.
Make sure that the following requirements for electrical control of the machine are
b
met such that the safety light curtain can fulfill its protective function.
– The external power supply of the safety light curtain must be capable of buffering
brief power failures of 20 ms as specified in EN 60204-1.
– The power supply unit must provide safe isolation according to IEC 61140
(SELV/PELV). Suitable power supplies are available as accessories from SICK, see
"Ordering information, accessories", Page 53.
4.4.1Restart interlock and external device monitoring
A restart interlock and/or verification of the external switching elements (external de‐
vice monitoring) must be implemented depending on applicable national regulations or
required reliability of the safety function.
Restart interlock A restart interlock prevents the machine from starting again as long as the operator
does not explicitly reset it. The dangerous state of the machine (1) is stopped if the
light path is interrupted (2) and is not re-enabled (3) until the operator presses the re‐
set device (4).
Figure 14: Schematic representation of operation with restart interlock
The restart interlock should not be confused with the start interlock of the machine.
The start interlock prevents the machine from starting after switching on. The restart
interlock prevents the machine from starting again after a fault or an interruption in the
protective field.
22
There must be a restart interlock depending on the applicable national regulations
when a person can stand behind the safety light curtain. The safety light curtain does
not have an internal restart interlock. Therefore, a restart interlock must be implemen‐
ted externally via the circuitry or the control, e.g. in connection with the SICK switching
amplifier UE48-2OS/UE48-3OS.

The safety light curtain can be connected to the UE48-2OS switching amplifiers. It is
operated with restart interlock and external device monitoring.
Functionality
When the protective field is clear, the OSSD1 and OSSD2 outputs carry voltage. The
system can be switched on when K1 and K2 are in the de-energized position. Pressing
the S1 button switches on the UE48 switching amplifier. Contacts 13-14 and 23-24 of
the UE48 activate the K1 and K2 contactors.
When the protective field is interrupted, the OSSD1 and OSSD2 outputs carry no volt‐
age. The UE48 switches off and K1, K2 are deactivated.
Fault analysis
Failure of K1 and K2 does not cause the loss of the shut-down function. Cross-circuits
and short-circuits of the OSSD1 and OSSD2 outputs are recognized and lead to the
locking state. It is recognized if the K1 or K2 contactors does not de-energize.

When active, the outputs are tested cyclically (brief LOW). When selecting the downstream controllers,
make sure that the test signals do not result in deactivation when using the above parameters.
5)
Make sure to limit the individual conductor resistance to the downstream controller to this value to en‐
sure that a cross-circuit between the outputs is safely detected. (Also note EN 60204 Electrical Machine
Equipment, Part 1: General Requirements.)

rectives/standards applicable to the machine?
Are the applied directives and standards listed in the declaration of conformity? Yes No
Does protective device comply with the required PL/SILCL and PFHd in accord‐
ance with EN ISO 13849-1/EN 62061 and type acc. to EN 61496-1?
Is the access to the hazardous area/hazardous point only possible through the
protective field of the ESPE?
Have appropriate measures been taken to prevent (mechanical point-of-opera‐
tion guarding) or monitor unprotected presence in the hazardous area when
protecting a hazardous area/hazardous point and have these been secured
against removal?
Are additional mechanical protective measures fitted and secured against ma‐
nipulation which prevent reaching below, above or around the ESPE?
Has the maximum shutdown and/or stopping time of the machine been meas‐
ured, specified and documented (at the machine and/or in the machine docu‐
mentation)?
Has the ESPE been mounted such that the required minimum distance from the
nearest hazardous point has been achieved?
Are the ESPE devices properly mounted and secured against manipulation after
adjustment?
Are the required protective measures against electric shock in effect (protection
class)?
Is the control switch for resetting the protective devices (ESPE) or restarting the
machine present and correctly installed?
Are the outputs of the ESPE (OSSD) integrated according to required PL/SILCL
compliant with EN ISO 13849-1/EN 62061 and does the integration corre‐
spond to the comply with the circuit diagrams?
Has the protective function been checked in compliance with the test notes of
this documentation?
Are the given protective functions effective at every setting of the operating
mode selector switch?
Are the switching elements activated by the ESPE, e.g. contactors, valves, moni‐
tored?
Is the ESPE effective over the entire period of the dangerous state?Yes No
Once initiated, will a dangerous state be stopped when switching the ESPE on
or off and when changing the operating mode, or when switching to another
protective device?
Has the ”Important Information” label for the daily check been attached such
that it is well visible for the operator?
