3 Product description
3.1 Structure and function
Overview
The deTec4 safety light curtain is an electro-sensitive protective device (ESPE) consist‐
ing of a sender and receiver.
A series of parallel infrared light beams forms a protective field between sender and
receiver that protects the hazardous area (hazardous point, access, and hazardous
area protection). When one or more beams are completely interrupted, the safety light
curtain reports the interruption in the light path to the secure output signal switching
devices (OSSDs) by a signal change. The machine or its control must safely analyze the
signals (for example using a safe control or safety relays) and stop the dangerous state.
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required, but is advantageous.

s
Figure 2: 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 reliably detected.
Protective field width
The protective field width is the dimension of the light path between sender and
receiver. The maximum protective field width is limited by the scanning range.
Resolution
The resolution describes the size of the smallest object detected by the safety light
curtain in the protective field. The resolution corresponds to the diameter of the test rod
belonging to the safety light curtain.
The safety light curtain has a resolution of 14 mm. This resolution provides finger
protection.

The safety light curtain has a resolution of 30 mm. This resolution provides hand
protection.
Scanning range
The scanning range is the maximum protective field width.
The scanning range is reduced by using deflector mirrors.
The scanning range is reduced by using a weld spark guard.

3.2.2 Absence 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
zones reduces the space requirement when integrated in the machine.
Exception: If the end cap on the receiver contains an integrated LED, the protective
function of the device only extends to below the LED.

3.2.3 Automatic calibration of the protective field width
When switched on, the safety light curtain automatically calibrates to the protective
field width.
3.2.4 Dynamic protective field width
For a dynamic protective field width, a range is configured. Within this range, the
protective field width may change during operation.
There are 3 dynamic protective field widths to choose from for each resolution of the
safety light curtain.
Table 2: Adjustable ranges for dynamic protective field widths

1) The minimum scanning range specifies a range in which a function is guaranteed to operate correctly and safely under industrial
conditions. A sufficient level of signal reserve to ensure very high availability is included in the calculation.
2) The typical scanning range specifies a range in which the safety light curtain operates correctly and safely under industrial conditions. The
level of signal reserve is enough to ensure high availability.

3.2.5 Beam coding.
Depending on its configuration, the safety light curtain operates with 1 of 3 beam
codings: uncoded, code 1 or code 2. The beam coding “uncoded” allows for particularly
short response times. In order to avoid mutual interference between 2 neighboring
safety light curtains, one can be operated with code 1 and the other with code 2.
3.2.6 Reduced resolution
Using a reduced resolution, up to 2 adjacent beams can be interrupted without the
OSSDs switching to the OFF state.
As a result, smaller objects can move into the detection area of the safety light curtain
without the curtain reacting and the machine switching off. For this purpose, the permit‐
ted resolution is reduced by up to 2 beams.
The reduced resolution can be used for suppressing interference objects, if, for
instance, cables or hoses need to be routed through the protective field. The function
can be configured during commissioning.
3.2.7 Alignment aid
A laser alignment aid is installed in the sender of the safety light curtain. The laser
alignment aid can be switched on to perform a simple alignment of the sender.
Diagnostic LEDs are installed in the receiver of the safety light curtain. For a simple
alignment of the receiver, diagnostic LEDs 1, 2, 3 and 4 indicate the alignment quality
once the safety light curtain has been switched on.
Diagnostic LEDs 5 and 6 light up if the topmost beam (far from system plug) is
synchronized. Diagnostic LEDs 7 and 8 light up if the bottommost beam (near system
plug) is synchronized.

3.2.8 Restart interlock
The safety light curtain has an integrated restart interlock. The function can be config‐
ured during commissioning.
A restart interlock prevents the machine from starting again once the protective device
has been triggered. The operator must first press a reset pushbutton to allow the
protective device to resume its monitoring function. The operator can then restart the
machine.
The reset pushbutton can be connected locally to the extension connection or in the
control cabinet.
3.2.9 External device monitoring (EDM)
The safety light curtain has integrated external device monitoring. The function can be
configured during commissioning.
The external device monitoring (EDM) monitors the status of downstream contactors.
In order to use external device monitoring, positively guided contactors must be used
to switch off the machine. If the auxiliary contacts of the positively guided contactors
are connected to the external device monitoring, the external device monitoring checks
whether the contactors switch correctly when the OSSDs are switched off.
3.2.10 Application diagnostic output
The safety light curtain has an application diagnostic output on the system connection
and on the extension connection.
Depending on the configuration, the application diagnostic output signals a certain
status of the safety light curtain, e.g. if the reset pushbutton must be engaged or if
there is a weak signal at the receiver.
For a signal of the safety light curtain to be displayed, a light can be connected to
the application diagnostic output or the signal can be transmitted to the machine
controller.
The following signals can be output over the application diagnostic output:
•Reset required
•Weak signal
•Ignored object
•Muting status
•Override required
•Valid object for Smart Box Detection
3.2.11 Cascading
Cascading allows up to 3 safety light curtains to be connected in series, e.g. for reliable
presence detection. The device connected to the control cabinet is the host device. The
subsequent sensors are called guest 1 and guest 2.
3.2.12 Smart presence detection
Overview
The safety light curtain features smart presence detection for access and hazardous
area protection. The function can be configured during commissioning.

8021645/1EB0/2022-04-28 | SICK O P E R A T I N G I N S T R U C T I O N S | deTec4 15
Subject to change without notice

Principle of operation
Smart presence detection is implemented using a cascade. The guest system is only
active if the protective field of the host system has been interrupted. The OSSDs then
change to the OFF status and the machine is stopped. As long as the protective field of
the host or guest system is interrupted, machine start-up is not possible.
If all of the protective fields have been clear for at least 0.5 s, the OSSDs change back
to the ON state and the guest system returns to sleep mode.
Smart presence detection prevents an unintentional machine shut-off, for example if
chips fall into the hazardous area protected by the guest systems.
3.2.13 Muting
Muting temporarily bypasses the protective action of the safety light curtain so that
material can be transported to or from a machine or system. As a result, the work
process remains uninterrupted. The function can be configured during commissioning.
The distinction between people and materials is made by 2 signals that are independ‐
ent of each other. Based on the logical evaluation of these signals, the protective device
is bypassed if a valid muting condition is present. As soon as something other than
material enters the hazardous area, the work process is interrupted.
3.2.14 Partial blanking
During partial blanking, only the topmost beam of the protective field remains active if
a valid muting condition is present. All other beams are temporarily bypassed (e.g. for a
certain object height). As soon as the topmost beam is interrupted, the OSSDs switch to
the OFF status.
3.2.15 Smart Box Detection
Smart Box Detection enables human-material differentiation by conveying only geomet‐
rically uniform objects to or from a plant or machine.
The protective field always remains active, meaning interruption in the protective
field above an object is reliably detected by the protective device and the dangerous
machine state is stopped.
3.2.16 IO-Link
Overview
The safety light curtain can communicate with an IO-Link master via an IO-Link connec‐
tor, which is available as an accessory.
The following information can be output via IO-link:
•Application diagnostic output status information
•Device information and device status
•Configuration of the device
•Status of each individual light beam
•Error history
•Reasons for the last lockout
The following information can be controlled via IO-link:
•LED signal behavior of the field indicator
•LED light behavior of the integrated indicator lamp on the receiver (optional)
•Switching on and off of the integrated laser alignment aid

3.2.17 Near Field Communication (NFC)
Overview
The receiver of the safety light curtain has an integrated NFC interface for transmitting
diagnostic data of the protective device to an NFC-capable device.
The integrated NFC interface is intended for temporary use.
Diagnostic data
The following diagnostic data can be displayed in an NFC-capable device:
•Device-specific information of the protective device, e.g. name, serial number, type
code
•Information on configuration, e.g. whether the restart interlock is activated
•Current status of the protective device, e.g. status of the OSSDs, quality of the
alignment
•Error diagnostics with specification of the error code, error description, diagnostic
LED and error correction
An NFC-capable antenna is integrated behind the front screen of the safety light curtain
for transmitting the data. The area is marked with the NFC-symbol.
Figure 4: NFC symbol 1)
To be able to call up information for diagnostics and configuration, you need an NFC-
capable device, e.g. a smartphone and the app provided by SICK.
bHold the NFC-capable mobile device near the marked NFC-area on the lower end
of the receiver to call up the diagnostic data.
3.2.18 System plug
