3.1 SBV System Series
3.1.1 Definition
SBV 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:
ldetection of current distance and angle of the targets detected by each sensor
lup to four safe detection fields to define different behaviors of the machines
lprogrammable coverage angle for each detection field
lrotation on three axes during installation to allow better coverage of detection areas
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
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
SBV 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 number (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16 and "Outputs" on page17).
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23.
The ISC-B01 and ISC-02 control units are provided with an Ethernet port that allows an unsafe communication
on a Modbus interface. See "Modbus communication" on page24.
3.1.6 Applications
SBV System Series integrates with the machinery control system: when performing safety functions or detecting
failures, SBV 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, SBV System Series can be connected to the devices that control the
power supply or machinery start-up.
SBV System Series does not perform normal machinery control functions.
For connection examples, see "Electrical connections" on page84.

3.2.6 Inputs
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78).
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:

lperform the correct input diagnostic
lassure the system safety level
The function of each digital input must be programmed through the Inxpect Safety application. The available
functions are the following:
lStop signal: optional safety function, manages a specific signal to force all the safety outputs (detection
signals, if present) to OFF-state.
lRestart signal: optional safety function, manages a specific signal which enables the control unit to switch to
ON-state the safety outputs related to all the detection fields with no motion detected.
lMuting group “N”: optional safety function, manages a specific signal which allows the control unit to ignore
the information coming from a selected group of sensors.
lActivate dynamic configuration: allows the control unit to select a specific dynamic configuration.
lFieldbus controlled (if available): monitors the input status through Fieldbus communication. For example, a
generic ESPE can be connected to the input, respecting electrical specifications.
For details about digital input signals, see "Digital input signals" on page94.
3.2.7 Input variable behavior
If neither digital input nor OSSD is configured as Fieldbus controlled, the behavior of the input variables is as
described below:
Condition Input variable behavior Output behavior
IOPS (PLCprovider status)
=bad
the last valid value of the input
variable is retained
the system keeps working in its
normal operating state
Connection loss the last valid value of the input
variable is retained
the system keeps working in its
normal operating state
After power-up the initial values (set to 0) are used
for the input variables
the system keeps working in its
normal operating state
If at least one digital input or OSSD is configured as Fieldbus controlled, the behavior of the input variables is as
described below:
Condition Input variable behavior Output behavior
IOPS (PLCprovider status)
=bad
the last valid value of the input
variable is retained
the system keeps working in its
normal operating state
Connection loss the last valid value of the input
variable is retained
the system transits to safe state,
deactivating the OSSDs, until the
connection is re-established.
After power-up the initial values (set to 0) are used
for the input variables
the system remains in a safe state
with the OSSDs deactivated, until the
input data are passivated.
3.2.8 SNS input
The control unit also has an SNS input (high logic level (1) = 24 V) to check the correct functioning of the chip that
detects the status of the inputs.
NOTICE: if at least one input is connected, the SNS input "V+ (SNS)" and the GND input "V- (SNS)" must also be
connected.
3.2.9 Outputs
The system has four digital OSSD short-circuit protected outputs that can be used individually (non safe) or can
be programmed as dual channel safety outputs (safe) in order to ensure the system safety level.
An output is activated when it switches from OFF to ON-state and it is deactivated when it switches from ON to
OFF-state.
The function of each digital output must be programmed through the Inxpect Safety application.
The available functions are the following:
lSystem diagnostic signal: switches the selected output to OFF-state when a system fault is detected and
switches all the OSSD related to detection signals, if any, to OFF-state.

lMuting enable feedback signal: switches the selected output to ON-state in the following cases:
owhen a muting signal is received over the configured input and at least one group is in muting
owhen a muting command is received through Fieldbus communication (if available) and at least one
sensor is in muting
lDetection signal 1: (e.g. alarm signal) switches the selected output to OFF-state when a sensor detects a
motion in detection field 1, when a stop signal is received from the related input or when there is a system
failure. The selected output remains in OFF-state for at least 100 ms.
Note: when an OSSD is configured as detection signal 1, a second OSSD is automatically assigned to it to
provide a safe signal.
lDetection signal 2: switches the selected output to OFF-state when a sensor detects a motion in detection
field 2, when a stop signal is received from the related input or when there is a system failure. The selected
output remains in OFF-state for at least 100 ms.
Note: when an OSSD is configured as detection signal 2, a second OSSD is automatically assigned to it to
provide a safe signal.
lDetection signal 3: switches the selected output to OFF-state when a sensor detects a motion in detection
field 3 or when a stop signal is received from the related input or when there is a system failure. The
selected output remains in OFF-state for at least 100 ms.
Note: when an OSSD is configured as detection signal 3, a second OSSD is automatically assigned to it to
provide a safe signal.
lDetection signal 4: switches the selected output to OFF-state when a sensor detects a motion in detection
field 4 or when a stop signal is received from the related input or when there is a system failure. The
selected output remains in OFF-state for at least 100 ms.
Note: when an OSSD is configured as detection signal 4, a second OSSD is automatically assigned to it to
provide a safe signal.
lFieldbus controlled (if available): allows the specific output to be set through the Fieldbus communication.
lRestart Feedback signal: switches the selected output to ON-state when it is possible to restart at least
one detection field (Restart signal).
oIf all the used detection fields are configured as automatic restart prevention (in Settings >Restart
parameters), the dedicated output is always in OFF-state;
oIf at least one detection field in use is configured as manual or safe manual restart prevention (in
Settings >Restart parameters), the dedicated output remains in OFF-state as long as motion is
detected; then it is activated (ON-state) if there is no more motion within at least one detection field.
The ON-state lasts as long as the absence of motion within one or more detection field does and until
the restart signal is activated on the dedicated input.
Each output status can be retrieved by Fieldbus communication (if available).
The system installer can decide to configure the system as follows:
ltwo dual channel safety outputs (e.g. Detection signal 1 and Detection signal 2, usually alarm and warning
signals), or
lone dual channel safety output (e.g. Detection signal 1) and two single channel output (e.g. System
diagnostic signal and Muting enable feedback signal), or
leach output as a single output (e.g. System diagnostic signal,Muting enable feedback signal and a Restart
Feedback signal).
WARNING! To use SBV System Series for a category 3 safety system, both the channels of a safety
output must be connected to the safety system. Configuring a safety system with only one channel
safety output may result in serious injuries due to an output circuit fault and a failure of the machine
to stop.
The dual channel safety output is automatically obtained by the Inxpect Safety application and it only matches
the single OSSD outputs as follows:
lOSSD 1 with OSSD 2
lOSSD 3 with OSSD 4
In the dual channel safety output, the output status is the following:
lactivated output (24 V dc): no motion detected and normal functioning
ldeactivated output (0 V dc): motion detected in the detection field or failure detected in the system

Idle signal is 24 V dc, periodically shortly pulsed to 0 V (pulses are not synchronous) for the receiver to detect
shortcut to either 0 V or 24 V.
The pulse duration at 0 V (TL) can be set at 300 μs or 2 ms through the Inxpect Safety application (Settings >
Digital Input-Output >OSSD Pulse width).
For details, see "Technical references" on page78.
3.2.10 External resistor for OSSD outputs
To guarantee the correct connection between the OSSDs of the control unit and an external device, it may be
necessary to add an external resistor.
If the pulse width set (OSSD Pulse width) is 300 μs, it is strongly recommended to add an external resistor to
guarantee the discharge time of the capacitive load. If it is set at 2 ms, an external resistance must be added if
the resistor of the external load is greater than the maximum resistive load allowed, see "Technical data" on
page79.
Below are some standard values for the external resistor:
OSSD Pulse width value External resistor (Re)
300 μs 1 kΩ
2 ms 10 kΩ
