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

3.1 LBK System Series
3.1.1 Definition
LBK System Series is an active protection radar system that monitors the dangerous areas of machinery.
3.1.2 Special features
Some of the special features of this protection system are the following:
lup to two safe detection fields to signal proximity or prepare the machinery for stopping
lEthernet safety Fieldbus to safely communicate with the PLC of the machinery (if available)
lpossibility to switch dynamically between different preset configurations (max 32 through Fieldbus, if
available, and max 4 with digital inputs) to adapt to the surrounding reality
lthree configurable sensitivity levels
lmuting on the entire system or only on some sensors
limmunity to dust and smoke
lreduction of undesired alarms caused by the presence of water or processing waste
lcommunication and data exchange through Modbus (if available)

3.1.3 Main components
LBK System Series is composed of a control unit and up to six sensors. The Inxpect Safety application allows
system operation configuration and checks.
3.1.4 Control unit - sensor communication
The sensors communicate with the control unit via CAN bus using diagnostic mechanisms in compliance with
standard EN 50325-5 to guarantee SIL 2 and PL d.
For correct functioning, each sensor must be assigned an identification (Node ID).
Sensors on the same bus must have different Node IDs. By default, the sensor does not have a pre-assigned
Node ID.
3.1.5 Control unit - machinery communication
The control units communicate with the machinery via I/O ("Inputs" on page20 and "Outputs" on page21).
The ISC-B01 control unit is provided with a safety communication on a Fieldbus interface. The Fieldbus interface
allows the ISC-B01 control unit to communicate in real-time with the PLC of the machinery in order to do the
following:
lsend information about the system to the PLC (e.g. the position of the detected target)
lreceive information from the PLC (e.g. to change the configuration dynamically)
See "Fieldbus communication" on page26.
The ISC-B01 and ISC-02 are provided with an Ethernet port that allows an unsafe communication on a Modbus
interface. See "Modbus communication" on page27.
3.1.6 Applications
LBK System Series integrates with the machinery control system: when performing safety functions or detecting
failures, LBK System Series deactivates the safety outputs and keeps them deactivated, so the control system
can put the area into a safe condition and/or prevent restarting of the machinery.
In the absence of other control systems, LBK System Series can be connected to the devices that control the
power supply or machinery start-up.
LBK System Series does not perform normal machinery control functions.
For connection examples, see "Electrical connections" on page91.

3.2 LBK System Series control units
3.2.1 Control units supported
The LBK System Series supportsthree different control units. The main difference among them are the
connection ports and therefore the communication interfaces available:
lISC-B01: two Ethernet ports for Fieldbus, an Ethernet port for system configuration and Modbus
communication and a micro-USB port
lISC-02: an Ethernet port for system configuration and Modbus and a micro-USB port
lISC-03: a micro-USB port
Safe
Unsafe
ISC-B01 communication architecture. ISC-02 communication architecture.
ISC-03 communication architecture.
3.2.2 Functions
The control unit performs the following functions:
lCollects information from all the sensors via CAN bus.
lCompares the position of detected motion with the set values.
lDeactivates the dedicated safety output when at least one sensor detects motion in the detection field.
lDeactivates all the safety outputs if a failure is detected in one of the sensors or the control unit.
lManages the inputs and outputs.
lCommunicates with the Inxpect Safety application for all configuration and diagnostic functions.
lAllows dynamically switching between different configurations.
lCommunicates with a safety PLC through the Fieldbus connection (if available)
lCommunicates and exchanges data through Modbus protocol (if available)

The system has two type 3 digital inputs (according to IEC/EN 61131-2). Each digital input is dual channel, and
the ground reference is common for all the inputs (for details, see "Technical references" on page86).
When using digital inputs, it is mandatory that the additional SNS input "V+ (SNS)" is connected to 24 V dc and
that the GND input "V- (SNS)" is connected to the ground in order to:
