4.4.6
Universal inputs, universal outputs, universal I/Os
The safety laser scanner is equipped with universal inputs and universal outputs.
Depending on the device, a universal input can be used for resetting, external device
monitoring (EDM), sleep mode, or restarting the protective device, for example. If sleep
mode is activated by a universal input, the sleep mode must not be used for safety
applications. Certain universal inputs can also be used in pairs as a static control input.
A universal output outputs a signal depending on its configuration, e.g. if the reset
pushbutton needs to be pushed or if the optical cover is contaminated. A universal
output must not be used for safety functions.
b
Use the same earthing method for all devices that are electrically connected to the
safety laser scanner.
b
Voltage must be supplied in accordance with SELV/PELV (IEC 60204-1) for all
devices that are electrically connected to the safety laser scanner.
b
All devices connected to a local input or output of the safety laser scanner must
be in the same SELV/PELV circuit as the safety laser scanner.

is an Ethernet-based network for general and safety-related data communica‐
tion.
Devices can exchange data via EFI-pro, such as control signals, safety-related shut-off
signals, and diagnostics data.
An EFI-pro network can have various structures (topologies), e.g., with cables running
from one central device to all the others (star topology) or with cables running from
one device to the next (line topology). Different topologies can be combined within one
EFI-pro network to form a hybrid topology.
The connection can also be used for configuration, diagnostics, and data output.
Information about pin assignment:
see "Ethernet for EFI-pro, data output, configuration,
and diagnostics (XF1, XF2)", page 93
4.4.8
Depending on the regulations which apply at the place of installation, a restart interlock
may be required.
The restart interlock prevents the machine from automatically starting up, for example
after a protective device has responded while the machine is operating or after chang‐
ing the machine’s operating mode.
First, the operator must press a reset pushbutton to return the protective device to
monitoring status. Then, in a second step, the operator can restart the machine.
Depending on applicable national regulations, a restart interlock must be available if it
is possible to stand behind the protective field.
