If you connect the signal output, then you must configure it
with the aid of the SCD prior to commissioning. Details
can be found in the “Signal Output (ADO)” section on
page 29.
Notes Device configuration after replacement!
If you replace a safety light curtain on which the signal
output (ADO) is connected, then you must transfer the
configuration to the device again. It is not sufficient to
make the electrical connections, because new devices are
supplied ex factory with the signal output deactivated.
Test Input (Sender Test)
Figure 35: Connection of the sender test button
The sender test is performed when 0V is present at the test input
(pin 3).
To be able to use the sender test button, you must also
configure the Sender test function with the aid of the SCD:
Device symbol SafeShield safety light curtain Host
(sender), context menu Configuration draft, Edit, option
Enable sender test.
Notes If you do not connect the test input, then you must
deactivate the Sender test function with the aid of the
SCD. Otherwise, the safety light curtain remains
permanently red.

ATTENTION: Commissioning
requires a thorough check by qualified
personnel!
Before you operate a system protected by
the SafeShield safety light curtain for the first
time, make sure that the system is first
checked and approved by qualified
personnel. Please read the notes in the
“Safety” section on page 6.
Display Sequence During Power-Up
After the system is activated, sender and receiver go through a
power-up cycle. The 7-segment display indicates the device status
during the power-up cycle.
The display values have the following meaning:
Table 17: Displays shown during the power-up cycle
Aligning Sender and Receiver
After the light curtain has been mounted and connected, the
sender and receiver must be aligned in relation to each other. The
light beams emitted by the sender must hit the receiver with pin-
point accuracy.
Note If you wish to align a cascaded system, always align the
individual systems in the following sequence: host, guest 1,
guest 2.
How to align sender and receiver in relation to each other:
➢ Loosen the clamping bolts which hold the light curtain in place.
➢ Switch on the power supply to the light curtain.
➢ Watch the alignment information on the 7-segment display of
the receiver (see Table 18 below). Correct the alignment of the
sender and receiver, until the 7-segment display goes off.
➢ Using the clamping bolts, fix the light curtain in place.
Display Meaning
Testing the 7-segment display. All segments are activated
sequentially.
