2 Safety information
This chapter contains information on general safety for the safety light curtain.
More safety information about specific usage situations of the safety light curtain is
available in the respective chapters.
2.1 General safety notes
DANGER
Risk of ineffectiveness of the protective device
Persons or parts of the body to be protected are not recognized in case of non-observ‐
ance.
bPay particular attention to all warnings in these operating instructions.
2.2 Correct use
The deTec2 Core safety light curtain is an electro-sensitive protective device (ESPE)
and is suitable for the following applications:
– Hazardous point protection
– Access protection
– Hazardous area protection
The deTec2 Core safety light curtain must be connected to the control such that the
machine cannot start while persons are present in the hazardous area. If a person can
stand behind the safety light curtain, there must be a restart interlock depending on
the applicable national regulations.
The deTec2 Core safety light curtain must be only used within the limits of the prescri‐
bed and specified technical data and operating conditions at all times.
The requirements defined in the technical specifications, e.g. power supply, cables and
ambient conditions, must be observed and maintained to allow the safety light curtain
to meet its warranted function.
If the product is used for any other purpose or modified in any way, any warranty claim
against SICK AG shall become void.
Foreseeable misuse Among others, the deTec2 Core safety light curtain is not suitable for the following ap‐
plications:
– Outdoors
– Under water
– In potentially explosive atmospheres

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.
bThe width of the protective field must not change during operation of the safety light
curtain, see "Scanning range and protective field width", Page 16.
bThe components of the safety light curtain must not be tampered with, opened or
changed. Otherwise, any warranty claim against SICK AG shall become void.
bImproper repair of the protective device can lead to a loss of the protective function.
The protective device must be repaired by the manufacture or by someone author‐
ized by the manufacturer.
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 works as an indirect protective measure and cannot provide
protection from parts thrown out nor from emitted radiation. Transparent objects are
not detected.
bOnly use the safety light curtain as an indirect protective measure!
2.3 Requirements for the qualification of personnel
The safety light curtain must be configured, installed, connected, commissioned and
serviced only by qualified safety personnel.
Project planning For project planning, a person is considered competent when he/she has expertise and
experience in the selection and use of safety equipment on machines and is familiar
with the relevant technical rules and national work safety regulations.
Mechanical installation
and commissioning
For mechanical installation and commissioning, a person is considered competent
when he/she has the expertise and experience in the relevant field and is sufficiently
familiar with the application of the protective device on the machine that he/she can
assess its work safety aspects.
Electrical installation For electrical installation and commissioning, a person is considered competent when
he/she has the expertise and experience in the relevant field and is sufficiently familiar
with the application of the protective device on the machine that he/she can assess its
work safety aspects.
Operation and mainte‐
nance
For operation and maintenance, a person is considered competent when he/she has
the expertise and experience in the relevant field and is sufficiently familiar with the ap‐
plication of the protective device on the machine and has been instructed by the ma‐
chine operator in its operation.
An operator must clean and check the safety light curtain.
Additional information for the operator of the machine: see "Operation", Page 39 and
"Regular cleaning", Page 42.

3 Product description
This chapter provides information on the operation of the safety light curtain and shows
examples of its range of use.
3.1 Structure 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.
