Glossary of terms
1
1oo2
(one out of two) Type of multi-channel architecture where one area is monitored by two sensors at the
same time.
A
Activated output (ON-state)
Output that switches from OFF to ON-state.
Angular coverage
Property of the field of view that corresponds to the coverage of 110° or 50° on the horizontal plane.
D
Dangerous area
Area to be monitored because it is dangerous for people.
Deactivated output (OFF-state)
Output that switches from ON to OFF-state.
Detection distance 1
Depth of the field of view configured for detection field 1.
Detection distance 2
Depth of the field of view configured for detection field 2.
Detection field 1
Area of the fieldset closer to the sensor. In the absence of detection field 2, it corresponds to the whole
fieldset.
Detection field 2
Area of the fieldset that follows detection field 1.
Detection signal 1
Output signal that describes the monitoring status of detection field 1.
Detection signal 2
Output signal that describes the monitoring status of detection field 2.

E
ESPE (Electro-Sensitive Protective Equipment)
Device or system of devices used for the safety-related detection of people or parts of the body. ESPEs
provide personal protection at machines and plants/systems where there is a risk of physical injury.
These devices/systems cause the machine or plant/system to switch over to a safe status before a
person is exposed to a dangerous situation.
F
Field of view
Sensor area of vision characterized by a specific angular coverage.
Fieldset
Structure of the field of view which can be composed of one or two detection fields.
FMCW
Frequency Modulated Continuous Wave
I
Inclination
Sensor rotation around the x-axis. The sensor inclination is the angle between the center of the field of
view of the sensor and a line parallel to the ground.
M
Machinery
The system for which the dangerous area is monitored.
Monitored area
Area that is monitored by the system. It is composed of detection field 1 (e.g. used as alarm area) and
detection field 2 (e.g. used as warning area) of all the sensors.
O
OSSD
Output Signal Switching Device
R
RCS
Radar Cross-Section. Measure of how detectable an object is by radar. It depends, among other factors,
on the material, dimension and position of the object.
T
Tolerance area
Area of the field of view where detection or not of a moving object/person depends on the
characteristics of the same object itself.

2.1.4 SAFETY ASSESSMENT
Before using a device, a safety assessment in accordance with the Machinery Directive is required.
The product as an individual component fulfills the functional safety requirements in accordance with the
standards stated in "Standards and Directives" on page10. However, this does not guarantee the functional
safety of the overall plant/machine. To achieve the relevant safety level of the overall plant/machine’s required
safety functions, each safety function needs to be considered separately.

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:
lAccess detection function: access to a hazardous area deactivates the safety outputs to stop the moving
parts of the machinery.
lRestart 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:
lStop signal: force all the safety outputs to OFF-state.
lRestart signal: enables the control unit to switch to ON-state the safety outputs related to all the detection
fields with no motion detected.
lMuting (see "Muting" on page44).
LBK System Series is suitable for protecting the entire body for the following applications:
ldangerous area protection
lindoor and outdoor applications
The following is deemed improper use in particular:
lAny component, technical or electrical modification to the product,
lUse of the product outside the areas described in this document,
lUse of the product outside the technical details, see "Technical data" on page87.
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
lIncorrect 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.
lChanges 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.
lIf the system configuration allows access to the dangerous area without detection, implement additional
safety measures (e.g. guards).
lThe 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.
lThe system protection level (SIL 2, PL d) must be compatible with the requirements set forth in the risk
assessment.
lCheck 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.
lRadiation from this device does not interfere with pacemakers or other medical devices.
2.1.8 WARNINGS FOR THE RESTART PREVENTION FUNCTION
lThe restart prevention function is not guaranteed in blind spots. If required by the risk assessment, implement
adequate safety measures in those areas.
lMachinery restarting must be enabled only in safe conditions. The button for the restart signal must be
installed:
ooutside of the dangerous area
onot accessible from the dangerous area
oin a point where the dangerous area is fully visible
