2.1.5 INTENDED USE
LBK System Series is certified SIL 2 according to IEC/EN 62061 and PL d according to EN ISO 13849-1.
It performs the following safety functions:
l Access detection function: access to a hazardous area deactivates the safety outputs to stop the moving
parts of the machinery.
l Restart prevention function: prevents unexpected starting or restarting of the machinery. Detection of
motion within the dangerous area maintains the safety outputs deactivated to prevent machinery starting.
It performs the following optional safety functions:
l Stop signal: force all the safety outputs to OFF-state.
l Restart signal: enables the control unit to switch to ON-state the safety outputs related to all the detection
fields with no motion detected.
l Muting (see "Muting" on page44).
LBK System Series is suitable for protecting the entire body for the following applications:
l dangerous area protection
l indoor and outdoor applications
The following is deemed improper use in particular:
l Any component, technical or electrical modification to the product,
l Use of the product outside the areas described in this document,
l Use of the product outside the technical details, see "Technical data" on page87.
2.1.6 EMC-COMPLIANT ELECTRICAL INSTALLATION
NOTICE: The product is designed for use in an industrial environment. The product may cause interference if
installed in other environments. If installed in other environments, measures should be taken to comply with the
applicable standards and directives for the respective installation site with regard to interference.
2.1.7 GENERAL WARNINGS
l Incorrect installation and configuration of the system decreases or inhibits the protective function of the
system. Follow the instructions provided in this manual for correct installation, configuration and validation of
the system.
l Changes to the system configuration may compromise the protective function of the system. After any
changes made to the configuration, validate correct functioning of the system by following the instructions
provided in this manual.
l If the system configuration allows access to the dangerous area without detection, implement additional
safety measures (e.g. guards).
l The presence of static objects, in particular metallic objects, within the field of view may limit the efficiency of
sensor detection. Keep the sensor field of view unobstructed.
l The system protection level (SIL 2, PL d) must be compatible with the requirements set forth in the risk
assessment.
l Check that the temperature of the areas where the system is stored and installed is compatible with the
storage and operating temperatures indicated in the technical data of this manual.
l Radiation from this device does not interfere with pacemakers or other medical devices.
2.1.8 WARNINGS FOR THE RESTART PREVENTION FUNCTION
l The restart prevention function is not guaranteed in blind spots. If required by the risk assessment, implement
adequate safety measures in those areas.
l Machinery restarting must be enabled only in safe conditions. The button for the restart signal must be
installed:
o
outside of the dangerous area
o
not accessible from the dangerous area
o
in a point where the dangerous area is fully visible
