WARNING
Ineffectiveness of the protective device
In the case of non-compliance, it is possible that the dangerous state of the machine
may not be stopped or not stopped in a timely manner.
b
When operating two safety laser scanners in a system network (communication
via EFI), use the same earthing method for both safety laser scanners.
NOTICE
b
Ensure adequate arc suppression at the relays (contactors). Keep in mind that arc-
suppressors can extend the response time.
b
Lay the arc-suppressors parallel to the relays (contactors) (not over the contacts).
NOTE
In the case of the examples with an S3000 Expert or Flexi Soft, the universal I/O con‐
nections must be configured in such a way that they display the relevant states.
NOTE
When using two safety laser scanners connected via EFI in an application, the input sig‐
nals must be connected to just one safety laser scanner. It is not possible to distribute
the input signal connections across two safety laser scanners.

Meaning
k1 and k2 or k3 and k4
Output circuits
Incorporate these contacts into the controller in such a way that
the dangerous state is brought to an end if the output circuit is
open. For categories 3 and 4, they must be incorporated on dual-
channels (x, y paths) in accordance with EN 13849-1. Observe the
maximum values when loading the outputs (
).
FE
Functional earth
To achieve the specified EMC safety, the functional earth (FE)
must be connected, e.g., to the central earth star point of the vehi‐
cle or system.
H2
Signaling device for fault or contamination
H3
Signaling device for Reset required
H8
Signaling device for warning field interruption
