6.1
Preparation
•
Sender and receiver must be well aligned,
.
•
First put the receiver into operation, then the sender. After connecting the sensors,
the green LED must light up on the sender and receiver (for IO-Link communica‐
tion, the LEDs flash at 1 Hz (otherwise constantly on)).
•
With
Auto-Teach
active: 2 s ... wait 26 s until the yellow LED stops flashing at 1 Hz.
3)
•
Check alignment again. As an alignment aid, the
Alignment aid
function is also
available via SOPAS ET,
•
No objects should be located between the sender and the receiver. The light path
must be clear.
6.2
Teach-in
After preparation, a teach-in can now be performed.
The duration of the teach-in process depends on the number of beams, the quality of
alignment, the distance between sender and receiver and the
Cross beam Setting
and
can be up to 24 s.
The teach-in automatically adjusts the switching threshold of each receiver element
to the received signal intensity. The signal intensity depends on the distance between
sender and receiver. The teach-in achieves the optimum resistance and detection
reliability.
For stable operation, it is therefore mandatory to perform a teach-in under the following
conditions:
•
After a power-up operation (
System-power-on
)
•
After each mechanical adjustment of the sender and/or receiver
•
After a
Factory reset
•
After a
Teach-in error
•
After beam blanking or resetting the beam blanking (
Beam blanking
)
•
After a
IO-Link data storage download
•
After changing the cross-beam setting (
Cross beam
)
•
After deactivating the
Alignment aid
If the teach-in was not performed correctly, the yellow LED on the SLG-2 receiver
flashes at 8 Hz for 5 seconds. At the same time, a teach-in error is communicated
via IO-Link,
. If the yellow LED flashes at 2 Hz, the signal strength is not
sufficient. In both cases, check the alignment of the sender and receiver and the free
light path between the sender and receiver.
There are different ways to perform the teach-in:
•
Auto teach-in
•
Teach-in via pin 2 / MF
•
Teach-in via IO-Link and SOPAS ET
6.2.1
Auto teach-in
The
Auto-Teach-in
is performed automatically under the following conditions:
3)
The duration depends on the number of beams and the setting of the light grid. See also chapters
“Initialization time” and "Teach-in time".
