7.5 Connection diagrams
Only use relays with positively guided contacts. The protection elements connected in
parallel with the contactors are used for arc-suppression.
Ensure that there is adequate arc-suppression at the relay contacts. Take into account
that arc-suppressors may lengthen the response time.
If you want to operate two safety laser scanners in a system (communication via EFI), then
the same earthing method must be used for both safety laser scanners.
The safety-related parts of the control system that effect the switching of the active
protective field must meet the requirements PL d as per EN ISO 13849-1 or SIL2 as per
IEC 62061:
in case of position-dependent switching by means of two independently wired signal
sources, e.g. two independent position switches
in case of velocity-dependent switching by means of two independently wired signal
sources, e.g. two independent encoders
in case of manual operating mode-dependent switching by means of a suitable manually
operated control switch
Sketch key
k1 and k2 or k3 and k4 = Output circuits
These contacts are to be connected to the controller such that, with the output circuit
open, the dangerous state is disabled. For categories 3 and 4 according to
EN ISO 13 849<1, the integration must be dual-channel (x/y paths). Observe the
maximum values for the loading of the outputs (see section 12.4 "Data sheet" on
page 147).
FE = Functional earth
To achieve the specified EMC safety, the functional earth (FE) must be connected (e.g. to
the vehicle's or system's central earth star point).
H2 = Sensor for error/contamination
H3 = Sensor for waiting for restart
H8 = Sensor for warning field interruption
In the case of the examples with S3000 Expert or Flexi Soft, the universal I/O connections
are to be configured such that they indicate the related states.
