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
Overview
The deTec4 Ex safety light curtain is an electro-sensitive protective device (ESPE) con‐
sisting 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 light beams are completely interrupted, the safety
light curtain reports the interruption in the light path to the secure output signal switch‐
ing 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.
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 cur‐
tain 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 30 mm. This resolution provides hand pro‐
tection.
Scanning range
The scanning range is the maximum protective field width.
The scanning range is reduced by using deflector mirrors.

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 1 of 3 beam cod‐
ings: 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.

3.2.4 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.
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 synchro‐
nized. Diagnostic LEDs 7 and 8 light up if the bottommost beam (near system plug) is
synchronized.
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.
3.2.6 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 the external device monitoring, positively guided contactors must be
used to switch off the machine. If the auxiliary contacts of the positively guided contac‐
tors are connected to the external device monitoring, the external device monitoring
checks whether the contactors drop off when the OSSDs are switched off.
3.2.7 Application diagnostic output
The safety light curtain has an application diagnostic output on the system connection.
Depending on the configuration, the application diagnostic output signals a certain sta‐
tus 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 con‐
troller.
3.2.8 System plug
Overview
The following system plugs are available for the safety light curtain:
•SP1 system plug
The system plugs are available in the following versions:
•System plug (flying leads, 8-wire)
The following functions are available depending on the system plug used:
•Beam coding
•Restart interlock
•External device monitoring (EDM)
•Application diagnostic output

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
The OSSD status and the status of the protective field are indicated via LEDs on the
sender and receiver when the following applies:
•The sender and receiver are connected to one another in the control cabinet
If the sender and receiver are not connected to each other, this status information is
only indicated at the receiver.
