1 Glossary of terms
Dangerous area Area to be monitored because it is dangerous for people.
Detection area Portion of the field of vision where detection is guaranteed.
Field of vision Sensor area of vision. It is composed of two areas: detection area
and uncer
tainty area. It can have two ranges: 110° and 50°
FMCW Frequency Modulated Continuous Wave
Machinery The system for which the dangerous area is monitored.
Monitored area Area actually monitored by the system. Includes the stopping area,
and onl
y for detection function, any pre-alarm area.
Pre-alarm area Only for the detection function. Area where motion detection trig‐
gers the closure of the dedicated auxiliary relay.
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 mea‐
sures must be introduced.
Tolerance area Portion of the monitored area where detection is not guaranteed.
Uncertainty area Area of the field of vision where detection or not of an object
depends on t
he characteristics of the same object.

3.1.3 Foreseen use
safeRS is certified as SIL 2 according to IEC/EN 62061 and PL d in accordance with EN
IS
O 13849-1. Performs the following safety functions:
•
detection function: prevents access to a dangerous area. Access to the area de-
energizes the safety relays to stop the machinery's moving parts.
•
restart 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.
safeRS is suitable for protecting the entire body.
safeRS has been designed to monitor dangerous areas in industrial environments.
Thanks to IP67 protection grade, the sensors are suitable for indoor and outdoor instal‐
lations.
safeRS is technically identical to the LBK System from manufacturer Inxpect.
safeRS control is technically identical to the LBK-C22 from manufacturer Inxpect.
safeRS sensor is technically identical to the LBK-S01 from manufacturer Inxpect.

3.1.4 General warnings
•
W
rong installation and configuration of the system decreases or inhibits the pro‐
tective function of the system. Follow the instructions provided in this manual for
correct installation, configuration and validation of the system.
•
Changes to the system configuration may compromise the protective function of
the system. After any changes made to the configuration, validate correct function‐
ing of the system by following the instructions provided in this manual.
•
If the system configuration allows access to the dangerous area without detection,
implement additional safety measures (e.g. guards).
•
The 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.
•
The system protection level (SIL 2, PL d) must be compatible with the require‐
ments set forth in the risk assessment.
•
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 techni‐
cal data of this manual.
3.1.5 Warnings for the restart prevention funktion
The restart prevention function is not guaranteed in blind spots. If required by the risk
a
ssessment, implement adequate safety measures in those areas.
Machinery restarting must be enabled only in safe conditions. The restart enable but‐
ton must be installed:
•
outside of the dangerous area
•
not accessible from the dangerous area
•
in a point where the dangerous area is fully visible
3.1.6 Responsibility
The machinery designer and system installer are responsible for:
•
Pr
oviding adequate integration of the system's outgoing signals (both safety and
auxiliary).
•
Checking 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.
3.1.7 Limits
•
T
he system does not detect the presence of inert people or objects within the dan‐
gerous area.
•
The system does not offer protection from pieces ejected from the machinery,
from radiation, and objects falling from above.
•
The machinery command must be electronically controlled.

4.1 safeRS
4.1.1 Description
safeRS is an active protection radar system that monitors the dangerous areas of a
mac
hinery. It performs two safety functions:
•
detection function: it places the machinery in safe conditions when someone
enters the dangerous area
•
restart prevention function: it inhibits the machinery restart if there are people in
the dangerous area
4.1.2 Inputs and outputs
Thanks to its digital inputs and outputs, safeRS provides an automatic control system
t
hat manages the primary safety functions of the machinery.
In addition to safety outputs, the system is also fitted with two configurable auxiliary
outputs (fault, pre-alarm and muting status) and three digital inputs (emergency button,
restart enable button and muting).
4.1.3 Special features
Some of the special features of this protection system are presented as follows:
•
resistant to dust, water, smoke and work waste
•
pre-alarm area to signal proximity or prepare the machinery for stopping
•
three configurable sensitivity levels
•
muting on the entire system or only on some sensors
4.1.4 Main components
safeRS is composed of a controller and up to six sensors. The safeRS Designer applica‐
t
ion allows configuration and inspection of system functioning.

4.1.5 Controller - sensors communication
The sensors communicate with the controller via CAN bus using diagnostic mecha‐
nisms in com
pliance with standard EN 50325-5 to guarantee SIL 2 and PL d.
For correct functioning, each sensor must be assigned with an identification (ID). Two
sensors on the same bus must have different IDs.
The default settings for the sensors is ID = 0, or no assigned ID.
4.1.6 Applications
safeRS integrates with the machinery control system: when performing safety functions
or de
tecting faults, safeRS de-energizes the safety relays and keeps them de-energized,
so the control system can command safety conditions of the area and/or prevent
restarting of the machinery.
In the absence of other control systems, safeRS can be connected to the devices that
control the power supply or machinery start-up (e.g. external relays on the power supply
line).
safeRS does not perform normal machinery control functions. For connection exam‐
ples, see "Electrical connections", page 67.
4.2 safeRS control
4.2.1 Functions
The controller performs the following functions:
•
C
ollects information from all the sensors via CAN bus.
•
Compares the position of detected motion with the set stopping and pre-alarm
thresholds.
•
De-energizes the safety output relays when at least one sensor detects motion in
the stopping area.
•
De-energizes the safety output relays if a fault is detected in the sensor or the con‐
troller.
•
Manages the auxiliary inputs and outputs (to learn about the functions see "Auxil‐
iary outputs", page 18 and see "Digital inputs", page 19).
•
Communicates with the safeRS Designer for all configuration and diagnostic func‐
tions.

The LEDs are each dedicated to a sensor, and can display the following statuses:
Status Meaning
Green Normal functioning and no detected motion
Orange Normal functioning and motion detected

4.2.4 Inputs and outputs status LED
The meaning of the LEDs when they are on is as follows:
LED Meaning
Safety output Energized relay (closed contact)
Auxiliary output Energized relay (closed contact)
Digital input High logic level (1)
4.2.5 Safety outputs
The controller has one dual channel safety output realized with forced guided safety
r
elays for alarms and, direct or indirect, safety of the machinery.
4.2.6 Safety outputs status
The relay contacts are normally open. The statuses of the safety outputs are as follows:
•
de
-energized relay (open contact):
°
motion detected in stopping area or
°
fault detected in system
•
energized relay (contact closed):
°
no motion detected and normal functioning
4.2.7 Auxiliary outputs
The controller has two relay outputs, which can be configured via the safeRS Designer,

•
machinery restart button enabled (high logic level (1) = restart enabled)
The inputs are type1, type 2 and type 3 (see "Voltage and current limits for digital
inputs", page 66). The function of the inputs can be configured through the safeRS
Designer.
4.2.10 SNS input
The controller also has an SNS in
put (high logic level (1) = 24 V) to check the correct
functioning of the chip that detects the status of the inputs.
NOTE
if a
t least one input is connected, the SNS input must also be connected.
