Beam coding
Depending on its configuration, the multiple light beam safety device operates with 1 of
2 beam codings: code 1 or code 2. In order to avoid mutual interference between 2
neighboring multiple light beam safety devices, one can be operated with code 1 and
the other with code 2.
3.2.3
Alignment aid
Diagnostic LEDs are installed in the active unit of the multiple light beam safety device.
For a simple alignment of the passive unit, diagnostic LEDs 1 … 8 indicate the align‐
ment quality once the device has been switched on.
The alignment quality of the beams close to the system connection are indicated via
the diagnostic LEDs 1 … 4. The alignment quality of the beams distant from the system
connection are indicated via the diagnostic LEDs 5 … 8.
3.2.4
Restart interlock
The multiple light beam safety device has an integrated restart interlock. The function
can be configured during commissioning.
A restart interlock prevents the machine from starting again once the protective device
has been triggered. First, the operator must press a reset pushbutton to return the pro‐
tective device to monitoring status. Then, in a second step, the operator can restart the
machine.
The reset pushbutton can be connected locally at the system connection or at the con‐
nection for the reset/override pushbutton.
3.2.5
Application diagnostic output
The multiple light beam safety device has an application diagnostic output at the sys‐
tem connection and at the connection for a reset/override pushbutton.
