Glossary of terms
D
Dangerous area
Area to be monitored because it is dangerous for people.
Detection area
Portion of the field of vision where detection is guaranteed.
F
Field of vision
Sensor area of vision. It is composed of two areas: detection area and uncertainty area. It can have
two ranges: 110° and 50°.
FMCW
Frequency Modulated Continuous Wave.
M
Machinery
The system for which the dangerous area is monitored.
Monitored area
Area actually monitored by the system. Includes the stopping area, and only for the access
detection function, any pre-alarm area.
P
Pre-alarm area
Only for the access detection function. Area where motion detection triggers the closure of the
dedicated auxiliary relay.
R
Rotation
Sensor rotation around the transverse axis. The sensor inclination is the angle between the center of
the field of vision of the sensor and a line parallel to the ground.
S
Stopping area
Portion of the area monitored by the sensor where, if motion is detected, the system safety relays
are de-energized. If it does not correspond to the dangerous area defined in the risk assessment,
the residual risk must be calculated and additional safety measures must be introduced.
Glossary of terms

T
Tolerance area
Portion of the monitored area where detection is not guaranteed.
U
Uncertainty area
Area of the field of vision where detection or not of an object depends on the characteristics of the
same object.

2.1.3 INTENDED USE
LBK System is certified as SIL 2 according to IEC/EN 62061 and PL d in accordance with EN ISO 13849-1.
Performs the following safety functions:
laccess detection function: prevents access to a dangerous area. Access to the area de-energizes the
safety relays to stop the machinery's moving parts.
lrestart prevention function: prevents unexpected starting or restarting of the machinery. Detection of
motion within the dangerous area maintains the safety relays de-energized to prevent machinery
starting.
LBK System is suitable for protecting the entire body.
LBK System has been designed to monitor dangerous areas in industrial environments. Thanks to IP67
protection grade, the sensors are suitable for indoor and outdoor installations.
2.1.4 GENERAL WARNINGS
lWrong 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.

LBK System| Instruction manual v1.3 SEP 2019 |LBK-System_instructions_en v1.3|© 2018-2019 Inxpect SpA 9
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 vision may limit the
efficiency of sensor detection. Keep the sensor field of vision 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.
2.1.5 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 restart enable button must be installed:
ooutside of the dangerous area
onot accessible from the dangerous area
oin a point where the dangerous area is fully visible
2.1.6 RESPONSIBILITY
The machinery designer and system installer are responsible for the operations listed below:
lProviding adequate integration of the system's outgoing signals (both safety and auxiliary).
lChecking the monitored area of the system and validating it based on the needs of the application and
risk assessment. Following the instructions provided in this manual.
2.1.7 LIMITS
lThe system cannot detect the presence of people who are immobile and not breathing or objects within
the dangerous area.
lThe system does not offer protection from pieces ejected from the machinery, from radiation, and objects
falling from above.
lThe machinery command must be electronically controlled.
