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 deTec4 Prime 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
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 evaluate the sig‐
nals reliably (e.g., by means of a safety controller or a safety relay) and bring an end to
the dangerous state.
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required, but is advantageous (see "Flexible
control cabinet cabling and status indication on both sides", page 16).
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. The size of the safety light curtain determines
the protective field height.

Subject to change without notice

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 cur‐
tain in the protective field. The resolution corresponds to the diameter of the test rod
belonging to the safety light curtain, which is reliably detected when in the protective
field.
With the appropriate resolution, the safety light curtain provides finger and hand protec‐
tion.
Information on protective field height, protective field width, and resolution: see "Data
sheet", page 81.
Scanning range
The scanning range is the maximum protective field width. It is subject to the resolution
variant (14 mm or 30 mm).
Information on protective field height, protective field width, and resolution: see "Data
sheet", page 81.
The scanning range is reduced by using deflector mirrors and/or a weld spark guard,
see "Deflector mirrors", page 100, see "Weld spark guard", page 95.
3.2 Product characteristics
3.2.1 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.
3.2.2 Automatic calibration of the protective field width
When switched on, the safety light curtain automatically calibrates to the protective
field width.
3.2.3 Beam coding
Depending on its configuration, the safety light curtain operates with one of three 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 two neighboring
safety light curtains, one can be operated with code 1 and the other with code 2.
3.2.4 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.
Alignment quality LEDs are installed in the receiver of the safety light curtain. To per‐
form a simple alignment of the receiver, the alignment quality LEDs indicate the align‐
ment quality once the safety light curtain has been switched on.

3.2.5 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 pro‐
tective 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.
3.2.6 External device monitoring (EDM)
The safety light curtain has integrated external device monitoring. The function can be
configured during commissioning.
External device monitoring monitors the status of the downstream contactors.
A requirement for the use of external device monitoring is that positively guided contac‐
tors are used to switch off the machine. If the auxiliary contacts of the positively guided
contactors are connected to external device monitoring, external device monitoring
checks whether the contactors drop out when the OSSDs are switched off.
3.2.7 Cascading
With cascading, up to three safety light curtains are connected in series, e.g., to provide
reliable presence detection. The device connected to the control cabinet is the host
device. The subsequent sensors are called guest 1 and guest 2.
3.2.8 System plug
The safety light curtain requires a system plug. The system plug is available in a range
of variants.
Depending on the variant, there are one or two M12 plug connectors on the system
plug:
•System plug with 5-pin system connection
•System plug with 8-pin system connection
•System plug with 5-pin system connection and 5-pin extension connection
•System plug with 8-pin system connection and 5-pin extension connection
System plug and functions of the safety light curtain
The following functions are available depending on the system plug used:
•Restart interlock
•External device monitoring (EDM)
•Application diagnostic output
•Cascading
Restart interlock
•Requirement for the receiver: 8-pin system connection or extension connection.
•Additional information see "Restart interlock", page 31.

•Requirement for the receiver: 8-pin system connection or extension connection.
•When the restart interlock is configured, the application diagnostic output located
on the same plug connector as the reset pushbutton signals when the reset push‐
button needs to be pressed.
•Otherwise, the application diagnostic output signals that the receiver is receiving a
weak signal from the sender, e.g., because the sender and receiver are not cor‐
rectly aligned or because the front screen is contaminated.
Cascading
•Requirements: extension connection at the host, 5-pin system connection at the
guest devices.
•Additional requirement for cascades with two guest devices: extension connection
at the first guest.
•Restart interlock, external device monitoring (EDM), and application diagnostic
output are possible if one of the following requirements is met:
°8-pin system connection at the host receiver.
°Extension connection at the last guest receiver of the cascade.
•Additional information: see "Cascading", page 34.

1) At the sender, the 8-pin system connection is solely for the purposes of providing standardized wiring. It is
particularly recommended if the 8-pin system connection at the receiver is used and the sender and
receiver are connected to each other via a T-piece.
2) If a sender does not have an additional guest connected to it, the extension connection has no function
and must be sealed with a protective cap.

System plug suitable. No additional function on the device.
System plug suitable. Restart interlock, external device monitoring (EDM), or application

3.2.9 Flexible control cabinet cabling and status indication on both sides
The safety light curtain can be connected to the control cabinet in different ways as
required:
•Separate connecting cables for sender and receiver
•Separate connecting cables for sender and receiver with connection in the control
cabinet
•Connection of sender and receiver via a T-piece, shared 5-pin or 8-pin connecting
cable to the control cabinet
In a cascade, only the host sender and host receiver are connected to the control cabi‐
net.
The OSSD status and the status of the protective field are indicated at the sender and
receiver via LEDs when the sender and receiver are connected in the control cabinet or
via a T-piece. If the sender and receiver are not connected to each other, this status
information is only indicated at the receiver.
3.2.10 Status indicators
The sender and receiver LEDs indicate the operating status of the safety light curtain.
