• Two universal I/O connections
The SafeZone Mini safety laser scanner operates correctly as a protective device only if the following conditions are met:
• The control of the machine, system or vehicle must be electrical.
• It must be possible to transfer the dangerous machine, system or vehicle state to a safe state using the OSSDs on the
SafeZone Mini at any time, i.e. before a person has reached the hazardous point or hazardous area.
Or:
It must be possible to transfer the dangerous state of the machine, the system, or the vehicle to a safe state at any time
using the OSSDs on a safety controller connected to the SafeZone Mini.
• The SafeZone Mini must be mounted and configured such that it detects objects as they enter the hazardous area (see
Chapter 5, “Mounting” on page 35 and Chapter 9, “Commissioning” on page 47).
• The safety laser scanner’s optical path must always remain clear and is not allowed to be covered by transparent
objects such as protective windows, Plexiglas, lenses etc. The safety laser scanner’s protective function can only be
ensured if the contamination measurement function is not bypassed by such measures.
Principle of operation
The SafeZone Mini is an optical sensor that scans its surroundings in two dimensions using infrared laser beams. It is used
to monitor hazardous areas on machines or vehicles.

Chapter 3Product description
The SafeZone Mini works on the principle of time-of-flight measurement. It sends out very short pulses of infrared light
(send pulses). At the same time an “electronic stopwatch” is started. When the light hits an object, it is reflected and
received by the safety laser scanner (receive pulses). From the time between sending and reception (t) the SafeZone
Mini calculates the distance to the object.
In the SafeZone Mini there is also a mirror rotating at constant speed that deflects the light pulses such that they cover an
arc of 270°. In this way an object can be detected in the protective field within 270°. The first beam of a scan starts at –45°
relative to the back of the safety laser scanner.
The SafeZone Mini sends a pulse of light with an angular resolution of 0.5° . As a result resolutions between 30 mm
(1.18 in.) and 70 mm (2.76 in.) can be achieved
.
Due to its active scanning principle, the SafeZone Mini does not require receivers or reflectors. This has the following
advantages:
• Your installation effort is lower.
• You can easily adapt the monitored area to the hazardous area on a machine.
• In comparison with contact sensors, electro-sensitive scanning is nearly wear-free.
Field set comprising protective field and warning field(s)
Protective fields and warning fields form the so-called field set. You can configure these field sets with the aid of the SCD
software. The fields can be configured as circular, rectangular or of arbitrary shape. If the area to be monitored changes,
then you can re -configure the SafeZone Mini in software without additional mounting effort.
You can configure field sets comprising one protective field and one or two warning fields.
The SafeZone Mini secures the hazardous area on a machine or vehicle. As soon as the safety laser scanner detects an
object in the protective field, it switches the OSSDs to the OFF state and thus initiates the shutdown of the machine or stop
of the vehicle.
Fig. 3: Field set with one
protective field and
two warning fields
You can define the warning fields such that the safety laser scanner detects an object before the actual hazardous area.
Warning field 1 can be used in particular fo r vehicle protection to detect an object even before the actual hazardous area
and to slowly retard the movement of the vehicle or bring it to a standstill. In this way the wear on the brakes on an AGV
can be reduced. Warning field 2 can also be used to trigger a warning signal.

Recommendation
A name can be assigned to the application configured as well as to the safety laser scanner(s). The names are saved in the
devices after the configuration is transferred. The name chosen may be, for example, the identifier for the vehicle, system
or the machine.
You enter the application name and the names of the safety laser scanners used in the SCD software.
Application name
Enter a name for your application. You can enter a name with a maximum of 16 characters.
If you assign unique application names, you may “reserve” the devices for certain duties. A machine maintenance person
comparing exchanged devices with the configuration data saved in the SCD software will be notified that the application
name does not match. He may then exchange these devices for those with the correct application name.
Name of the scanner
Enter a device name for each of the safety laser scanners in the system. You can enter names with a maximum of eight
characters.
Use meaningful names, e.g. “front” and “rear” for vehicle monitoring. Unique device names make the subsequent
configuration steps easier (for example on allocating the control inputs or the OSSDs).
User data
You can enter your name in the field Name of the user. You can enter a name with a maximum of 22 characters. This is
then added to the configuration protocol and in the diagnostics report.
Display direction of the sevensegment display
The depiction of numbers on the sevensegment display can be rotated by 180° with the aid of the SCD software. This is
useful, for example, when the SafeZone Mini must be rotated by 180° owing to the specific assembly.
If you rotate the numbers of the sevensegment display, the point in the sevensegment display goes out.
How to determine the display direction of the sevensegment display:
Under sevensegment display, activate the Rotated by 180° option. After the configuration draft has been
transferred to the SafeZone Mini, the numbers of the sevensegment display are rotated by 180°.

• 70 (2.8) (leg detection with larger protective field size)
• 150 (5.9) (whole body detection)
If this the case, the SafeZone Mini shuts down after
5seconds and signals.
Resolution
The maximum protective field range depends on the configured resolution. The following table shows the related
maximum protective field range at the resolutions that can be set:
Configured resolution [mm (in.)]Maximum protective field range [m (ft)]
The warning field can be configured to up to 8 m (26.25 ft) for all resolutions. The detection capability within the warning
Note
field is dependent on the remission of the objects to be detected (see Chapter 12, “Technical Specifications” on page 55).
Basic response time
The basic response time of the SafeZone Mini is 80 ms.
You may need to add supplements to the basic response time due to multiple sampling (see Chapter 12, “OSSD response
Note
times” on page 55).
Maximum protective field range
Depending on the configured resolution used (see Chapter 4, “Resolution” on page 16), the maximum protective field
range of the safety laser scanner is shown in the SCD software.
The maximum protective field range of the SafeZone Mini must be sufficient to cover the calculated protective field size

Chapter 4Configurable functions
ATTENTION
Note
You are not allowed to use the universal I/O connections for safety-relevant functions!
You are only allowed to use the universal I/O connections for signaling. You must never use the signals for controlling the
application or for safety-relevant func tions.
The SafeZone Mini has two universal I/O connections (see Chapter 6, “Round plug connector SafeZone Mini” on page 40).
You can configure these two connections for the following functions:
• Inactive (factory default setting)
As inputs (it is only possible to select one function per universal I/O connection):
• Stand-by
• External device monitoring (EDM) (see page 18)
• Resetting the restart interlock (see page 18)
As outputs (it is possible to select several functions per universal I/O connection, these functions are linked
together using an OR operator):
• Device error
• Contamination error
• Contamination warning
• Second warning field
• Reset required
Other functions that can be configured are dependent on the configuration of the universal I/O connections. For example,
you can only realize a restart interlock if you configure one of the universal I/Os as an input for resetting the restart
interlock.
The universal I/O connections are configured in the SCD software in the Universal I/O area. Fig. 7 shows a configuration
example.

Recommendation
Stand-by
If, in mobile applications, vehicles are not moved for a time, the OSSDs can be switched to the OFF state and the laser on
the SafeZone Mini can be switched off. In this way the power consumption of the device is reduced.
Use this function if, e.g. you use several vehicles and do not move them for a time.
The SafeZone Mini remains in the stand-by mode as long as the related input information is present.

Note
Internal OSSDs of the SafeZone Mini
If there is an object in the protective field, the internal OSSDs on the SafeZone Mini always switch. This can not be
configured differently in the SCD software.
External device monitoring (EDM) SafeZone Mini
The EDM checks if the contactors actually de-energize when the protective device is tripped. If you activate external device
monitoring, then the SafeZone Mini checks the contactors after each interruption of the protective field and prior to the
machine restart. The EDM can so identify if one of the contactors has welded, for instance. In this case the external device
monitoring places the system in a safe operational state and the OSSDs are not switched back to the ON state.
The table shows how the SafeZone Mini reacts if the external device monitoring detects a contactor malfunction:

Restart of the SafeZone
Mini Standard
ATTENTION
You can configure the restart behavior of the SafeZone Mini as follows:
• Without restart interlock
• With restart delay
• With restart interlock
You can configure the type of restart in the SCD software.
It is imperative that you configure the SafeZone Mini or the application with restart interlock if the
protective field can be left to approach the hazardous point or if a person cannot be detected by the
SafeZone Mini at every point in the hazardous area!
During the assessment, pay attention to whether the protective field can be left in the direction of the hazardous point, to
areas that are unprotected due to the mounting and the unprotected near range of the SafeZone Mini (see Chapter 5,
“Methods of preventing unprotected areas” on page 33).
Configuration of the SafeZone Mini without restart interlock
After the OSSDs on the SafeZone Mini have been switched to the OFF state due to an object in the protective field, the
OSSDs are re-enabled again immediately when there is no longer an object in the active protective field.
This configuration is only allowed …
• If an external restart interlock is realized on the machine controller
or
• If the protective field cannot be left in the direction of the hazardous point and if people can be detected by the
SafeZone Mini at every point in the hazardous area!
Restart delay for mobile applications
In mobile applications you can configure a restart delay from 2 to 60 seconds on the SafeZone Mini. The OSSDs on the
SafeZone Mini change to the ON state if there is no object in the protective field for the duration given.
This configuration is only allowed if the protective field cannot be left in the direction of the hazardous point and if a
person can be detected at every point in the hazardous area by the SafeZone Mini!

Configuration of the SafeZone Mini with restart interlock
Do not confuse the restart interlock with the star ting interlock on the machine. The starting interlock prevents the
machine starting after switching on. The restart interlock prevents the machine starting again after an error or a
protective field infringement.
The OSSDs on the SafeZone Mini change to the OFF state to initiate a machine or vehicle stop as soon as there is an
object in the protective field . They do not change to the ON state , even if there is no longer an object in the
protective field. The OSSDs only change to the ON state if the operator operates the control switch for restart or reset.
ATTENTION
Notes
Note
ATTENTION
Place the control switch for restart or reset outside the hazardous area in a place where it can clearly be
seen from the hazardous area!
Place the control switch for restart or reset outside the hazardous area such that it cannot be operated by a person in the
hazardous area. Ensure that the person who operates the control switch has a full view of the hazardous area.
• You will find examples on the connection of the internal restart interlock in Chapter 7, “Connection diagrams” on
page 43.
• If you do not use the internal restart interlock, then do not configure any of the universal I/Os as an input for
resetting (see Chapter 4, “Universal I/O connections of the SafeZone Mini” on page 17).
Reset
The reset function is often also called “preparation for restart.” In these operating instructions the term reset is used.
If you want to activate the restart interlock on the SafeZone Mini (internal) and also a restart interlock on the machine
(external), then each restart interlock has its own control switch.
After operating the control switch for the internal restart interlock (with protective field unoccupied) …
• The SafeZone Mini switches its OSSDs to the ON state.
• The LED on the SafeZone Mini illuminates green.
The external restart interlock prevents the machine from restarting. After resetting the SafeZone Mini the operator must
press the control switch to restart the machine controller.
Ensure that the correct sequence is followed!
The controller must be realized such that the machine only restarts if the SafeZone Mini is first reset and then the control
switch for restarting the machine controller is operated.
ATTENTION
Reset signals
If the SafeZone Mini safety laser scanner is operated using the “With restart interlock” function, then after a protective
field infringement and the subsequent clearing of the protective field, it requests a reset signal from the control system
(reset required).
The reset signal must be safety-related (single failure proof)!

Field sets
Fig. 9: Creating a field set in the SCD software
Note
ATTENTION
Configuring the protective field and warning field
With the aid of the SCD software you can configure the field set, which comprises a protective field and two warning
fields . During this process you configure the shape and size of the protective and warning fields. You can realize any
field shape required.
The area to be monitored is scanned radially by the SafeZone Mini. The SafeZone Mini cannot see through objects during
this process. The area behind objects that are in the area to be monitored (pillars, grilles, etc.) can thus not be monitored.
Protective fields and warning field can cover up an angle of up to 270° and have different radial scanning ranges
depending on the resolution configured (see Chapter 4, “Resolution” on page 16).
Check the protec tive fields configured!
Prior to commissioning the machine or vehicle, check the configuration of the protective fields using the instructions in
Chapter 9, “Commissioning” on page 47 and using the “Checklist” on page 70.
Note
Fig. 10: Configuring protective
field and warning field
ATTENTION
If the protective field or the warning fields stretch as far as a wall or another object (pillar, neighboring machine,
shelf), there should be a distance of 100 mm (3.94 in.) between the protective field or warning field and the object to
prevent false triggering .
Secure unprotected areas!
If it is possible to access a narrow strip between the protective field and a wall or another object, you must protect this
strip using additional measures (e.g. fence or floor protection).

Fig. 11: Reading the protective field
Chapter 4Configurable functions
Protective field or warning field suggested by the safety laser scanner
The SCD software can suggest the protective field or warning field in the field set editor. The safety laser scanner scans the
visible surrounding contour several times. From the data obtained the SCD software suggests the contour and size of the
field. The following figure shows an example for the reading of a protective field:
In those places at which the surrounding contour is smaller than the maximum protective field range (e.g. at ), the
protective field corresponds to the surrounding contour.
Note
ATTENTION
Fig. 12: Schematic diagram of
contour as reference
The measuring error tolerances for the SafeZone Mini are automatically subtracted from the protective field size. As a
result the protective field is slightly smaller than the surface covered .
In those places where the surrounding contour is larger than the protective field range , the protective field corresponds
to the possible scanning range.
Check the protective field suggested by the SCD software
The protective field suggested by the SCD software is not a replacement for the calculation of the minimum distance.
Calculate the minimum distance and check the effectiveness of the protective fields prior to commissioning the
application!
Pay attention to the descriptions in Chapter 5, “Mounting” on page 24, the notes in Chapter 9, “Commissioning” on page
47 and the “Checklist” on page 70.
Using the contour as a reference
In addition to the protective field, the SafeZone Mini can also monitor a contour (e.g. the floor in vertical applications).
For contour monitoring you define a contour segment . The contour segment comprises a positive and a negative
tolerance band.

The OSSDs on the SafeZone Mini change to the OFF state or the SafeZone Mini Remote signals if…
• There is an object in the protective field.
• The monitored surrounding contour is no longer in the tolerance band (e.g. if the position of the SafeZone Mini is
changed).
• You can define any number of contour segments.
• The contour segments must not be narrower than the configured resolution.
• At the points where a contour has been configured as a reference you cannot define warning fields. If, for example, you
use the floor as a reference for access protection, you cannot configure a warning field there. However, you can, e.g.,
configure a warning field to the left and right of the contour segment to control a warning signal on approach from the
side.
• The contour as reference function and the warning field 2 function are mutually exclusive.
You define the contour as a reference in the SCD software field set editor.
Vertical operation
In vertical operation (for access protection and hazardous point protection) according to CLC/TS 614963 you must always
configure the protective fields used with the contour as reference function.
Recommendation
Monitoring cases
ATTENTION
22Rockwell Automation Publication 10000337275 Ver 01—October 2014
Use lateral, vertical boundaries of the opening (e.g. door frame) and the floor as reference. If in this case the position of the
SafeZone Mini is changed in one or more planes, the distance to the reference changes and the SafeZone Mini switches its
OSSDs to the OFF state.
The SafeZone Mini supports a configuration with monitoring cases.
Ensure for each monitoring case that the minimum distance to the hazardous area is maintained!
See Chapter 5, “Mounting” on page 24.
You can configure the monitoring cases in the SCD software.
Each monitoring case includes …
• The input conditions, the so-called control signals, that control the activation of the monitoring case.
• A field set, comprising of protective field and warning field or fields.
• The multiple sampling for the field set.
Monitoring cases can be switched with the following input information:
• Static information
Page 25
Chapter 4Configurable functions
Multiple sampling
If multiple sampling is set, an objec t must be scanned several times before the SafeZone Mini switches its OSSDs to the OFF
state. In this way you can reduce the probability that insects, welding sparks or other particles result in the shutdown of
the system.
If a multiple sampling of three is configured, for instance, an object must be detected in the protective field three times in
succession before the SafeZone Mini switches the OSSDs to the OFF state.
ATTENTION
Table 7: Recommended
multiple sampling
Recommendation
The total response time is increased by the multiple sampling!
With a multiple sampling greater than two, note that you must add a supplement to the basic response time (see Chapter
12, “OSSD response times” on page 55)!
On the SafeZone Mini, a multiple sampling of two is the minimum setting. You can set the multiple sampling to up to 16
with the aid of the SCD software. The supplement to the basic response time resulting from your setting is displayed in the
SCD software.
ApplicationRecommended multiple sampling
Stationary under clean ambient conditions2 times
Vertical applications2 times
Mobile4 times
Stationary under dusty ambient conditions8 times
Using multiple sampling you can increase the availability of a system.
You can configure the multiple sampling in the SCD software. You can set individual multiple sampling for each
monitoring case.
Stand-by mode
If, in mobile applications, vehicles are not moved for a time (e.g. for battery charging), the OSSDs can be switched to the
OFF state and the laser on the SafeZone Mini can be switched off. In this way the power consumption of the device is
reduced.
In this way you also prevent the safety laser scanners from optically interfering with each other and entering an error
condition.
The function can be realized with the aid of the stand-by mode.
In order to switch to the stand-by mode, on the SafeZone Mini one universal I/O connection must be configured as stand-
by input. (see Chapter 4, “Universal I/O connections of the SafeZone Mini” on page 17).
A monitoring case is not occupied by the stand-by mode.

Chapter 5Mounting
Mounting
This chapter describes the preparation and completion of the mounting of the SafeZone Mini safety laser scanner.
Mounting requires four steps:
• Definition of the application and the necessary mounting location for the safety laser scanner
• Calculation of the protective field sizes and minimum distances (see EN ISO 13855)
• Mounting the safety laser scanner with or without mounting kits
No protective function without sufficient minimum distance!
Only if you configure the protective field such that there is an adequate minimum distance to the hazardous area, is
protection by the SafeZone Mini ensured.
Mount the SafeZone Mini in a dry place and protect the device from dirt and damage.
Notes
Avoid the installation of the SafeZone Mini in the vicinity of strong electric fields. These can, e.g., be produced by
welding cables, induction cables in the immediate vicinity and also by mobile telephones operated nearby.
Ensure that there are no obstacles in the area to be monitored in the field of view of the S afeZone Mini that could cause
interference or shadowing. Such shadowed areas cannot be monitored by the SafeZone Mini. If there are unavoidable
shadowed areas, check whether there is a risk. Take additional safety precautions as necessary.
Keep the area to be monitored free of smoke, fog, steam or other forms of air impurities. There must not be any
condensation on the optics cover. Otherwise the function of the SafeZone Mini may be impaired and incorrect
switching may occur.
Avoid placing highly reflective objects in the scan plane of the SafeZone Mini. Examples: Retroreflectors can affec t the
measurement results of the SafeZone Mini. Highly reflective objects within the protective field can blank a part of the
area to be monitored in certain circumstances.
Mount the SafeZone Mini such that it is not saturated by incident sunlight. Do not position stroboscopic and
fluorescent lights or other strong light sources directly in the scan plane as these may affect the SafeZone Mini in
specific circumstances.
Mark the protective field on the floor, if this is reasonable for the application (see EN 614961 in Chapter 7).

• Configuration of the protective field (Chapter 8, “Configuration”)
• Commissioning and checking of the installation (Chapter 9, “Commissioning”)
• Checking the function and safe shutdown (Chapter 9, “Test notes”)

Protective field size
The protective field must be so configured that a minimum distance (S) to the hazardous area is maintained. This safety
distance ensures that the hazardous point can only be reached after the dangerous state of the machine has been
completely stopped.
You can operate the SafeZone Mini in stationary horizontal operation with 30, 40, 50, or 70 mm (1.2, 1.6, 2.0, or 2.8 in.)

ATTENTION
Fig. 15: Minimum distance S
Ensure that a human leg can be detected with 70 mm (2.8 in.)resolution!
As per EN ISO 13855, mount the scan planes for horizontal stationary applications with 70 mm (2.8 in.) resolution at least
300 mm (11.8 in.) above the floor (see “Height of the scan plane at 70 mm resolution” on page 33).
The minimum distance S depends on:
• Approach speed of the body or parts of the body
• Stopping/run-down time of the machine or system
(The stopping/run-down time is shown in the machine documentation or must be determined by taking a
measurement.)
• Response time of the SafeZone Mini
• Supplements for general measurement errors and any measurement errors related to reflection
• Supplement for prevention of reaching over
• Height of the scan plane
• Possibly the time for switching between the monitoring cases

Supplement C for protection against reaching over
With a protective field installed horizontally, there is a risk that people may reach over the protective field and in this way
reach the hazardous area before the SafeZone Mini shuts down the dangerous state. For this reason the calculation of the
minimum distance must take into account a supplement to prevent persons from finding themselves in a hazardous
situation by reaching over (see EN ISO 13857) before the SafeZone Mini triggers.
The necessary supplement for the minimum distance is dependent on the height of the scan plane for the protective field.
At low heights the supplement is larger than at greater heights and .
In summary there are three usual variations of mounting the scan plane for the SafeZone Mini. The optimal variation
depends on the related application. Table 8 provides assistance making the selection.

additional measures. For applications that are accessible to the public, the mounting height may need to be reduced to
200 mm (7.87 in.)(on this subject see the appropriate regulations).

Notes
If you choose a resolution of 70 mm (2.8 in.) in the SCD software for hazardous area protection, a human leg may, in
certain circumstances, not be detected (e.g. scan to left and right of the bone ).
If you mount the SafeZone Mini higher, the scan plane is at fibula height and the leg is also detected with an object
resolution of 70 mm (2.8 in.) .
Access protection can be used when the access to the machine can be defined by physical means. For access protection the
SafeZone Mini detects the entry of an entire body.
• To ensure adequate access protection, a response time of 90 ms and a resolution of 150 mm (5.91 in.) or finer are
required .
• To protect the protective device against inadvertent adjustment or manipulation, you must use the contour of the
surroundings as a reference for the SafeZone Mini (see Chapter 4, “Using the contour as a reference” on p age 21).
Minimum distance
For access protection, a minimum distance (S) must be maintained between protective field and hazardous area. This
safety distance ensures that the hazardous point can only be reached after the dangerous state of the machine has been
completely stopped.

ATTENTION
Fig. 19: Minimum distance to the hazardous area
Hazardous point protection is necessary if the operator must remain near the dangerous state of the machine. Hand
protection is required for hazardous point protection.
The SafeZone Mini must therefore be configured with a resolution of at least 40 mm (1.6 in.)
Never use the SafeZone Mini for safety applications in which finger protection is required!
Due to the finest possible resolution of 30 mm (1.2 in.), the SafeZone Mini is not suitable for finger protection.
To protect the protective device against inadvertent adjustment or manipulation, you must use the contour of the
surroundings as a reference for the SafeZone Mini (see Chapter 4, “Using the contour as a reference” on page 21).
Minimum distance
For hazardous point protection, a minimum distance must be observed between protective field and hazardous point. This
safety distance ensures that the hazardous point can only be reached after the dangerous state of the machine has been
completely stopped.
Prevent reaching around or reaching behind the protective field!
Always mount the safety laser scanner such that reaching around and behind is impossible. Provide suitable additional
precautions as necessary.
The minimum distance S as defined in EN ISO 13855 and EN ISO 13857 depends on:

If the dangerous state is produced by a vehicle (e.g. AGV or fork lift), the hazardous area that is produced by the movement
of the vehicle is protected by the SafeZone Mini.
• The SafeZone Mini may only be used to protect vehicles powered by electric motor.
Notes
• In the following calculations only take into account the velocity of the vehicle, not the speed of the person walking.
This is based on the assumption that the person will recognize the danger and stand still.
• For vehicle protection, observe EN 1525 “Safety of industrial trucks. Driverless trucks and their systems.”
• If the application is to protect vehicles from collisions, then you may need to use different assumptions.
For a horizontally mounted mobile application, determine:
• Protective field length
• Protective field width
• Height of the scan plane
• Restart behavior
• Methods of preventing unprotected areas

ATTENTION
Fig. 24: Mounting height [mm (in.)]
Mount the SafeZone Mini such that the scan plane is at a maximum height of 200 mm (7.87 in.)!
In this way also persons lying down will be reliably detected. Tilting the protective field so that objects with a diameter of
200 mm (7.87 in.)are not detected, is not allowed. We recommend aligning the scan plane horizontally at 70 mm
(2.76 in.)
Methods of preventing
unprotected areas
Fig. 25: Unprotected areas
ATTENTION
Note
To produce the optimal scan plane, you can also mount the SafeZone Mini reversed.
During mounting the SafeZone Mini, areas may be found that are not covered by the safety laser scanner ().
Prevent or secure unprotected areas!
• Mount the SafeZone Mini such that there are no unprotected areas.
• For mobile applications, if the vehicle is accelerated to a maximum velocity of 0.3 m/s (11.8 in.s) in less than three
seconds when in operation, you must prevent personnel from entering the unprotected areas by means of mechanical
trim panels, switch strips or fitting the SafeZone Mini in the vehicle trim panels.

ATTENTION
Switch the entire machine/system off line!
The machine/system could unintentionally start up while you are connecting the devices.
Ensure that the entire machine/system is disconnected during the electrical installation.
Connect OSSD1 and OSSD2 separately!
You are not allowed to connect OSSD1 and OSSD2 together, otherwise signal safety will not be ensured.
Ensure that the machine controller processes the two signals separately.
Downstream contactors must be positively guided and monitored.
OSSD1
OSSD2
Only ever connect one downstream switching element to an OSSD!
Each output signal switching device (OSSD) is only allowed to be connected to one switching element (e.g. relay or
contactor). If several switching elements are required, you must choose a suitable form of contac t duplication.
OSSD1
OSSD2
Prevent the occurrence of a potential difference between the load and the protective device!
If you connect loads that are not reverse-polarity protected to the OSSDs or the safety outputs, you must connect the 0
V connections of these loads and those of the corresponding protective device individually and directly to the same 0 V
terminal strip. This is the only way to ensure that, in the event of a defect, there can be no potential difference
between the 0 V connections of the loads and those of the corresponding protective device.

Notes
Notes
SafeZone Mini
You will find all the inputs and outputs on the SafeZone Mini on the round plug connector on the connecting cable.
Connect the SafeZone Mini using pre-assembled extension cables (see Table 10 on page 41).
• All inputs and outputs on the SafeZone Mini are to be used only in the context specified.
• The round plug connectors are coded. If you use plug connectors other than the connectors intended, any claims
against Rockwell Automation under the warranty will be rendered void.
Wiring in accordance with EMC regulations
The quality of the shield is essentially dependent on the quality of the connec tion of the screen. In principle the best
screening action can only be achieved with the connection of the shield at both ends using large area connections.
If it is not possible to connect the screen via threaded fittings, connect the screen physically close, e.g. to a control
cabinet chassis using a metal clamp.
• If there is a PE in an installation, it can be used for the connection of t he FE. However a functional earth connec tion
(FE) is never allowed to be used as a PE!
Functional earth
To achieve the specified EMC safety, the functional earth FE must be connected (e.g. to the vehicle’s or system’s central
earth star point).

Vehicle monitoring for unidirectional travel (SafeZone Mini)
The SafeZone Mini monitors the area in the direction of travel and switches its OSSDs to the OFF state to stop the vehicle as
soon as there is an object in the protective field.
• Only use relays/contacts with positively guided contac ts. The protection elements connected in parallel with the
relays/contactors are used for arc-suppression.
• Ensure that there is adequate arc-suppression at the relays/ contactors. Take into account that arc-suppressors may
lengthen the response time.
• The arc-suppressors must be in parallel with the relays/contactors (not across the contacts).

Commissioning
ATTENTION
Table 12: Sevensegment display during and after
the power up sequence on initial commissioning
Commissioning requires a thorough check by qualified safety personnel!
Before you operate a system protected by the SafeZone Mini safety laser scanner for the first time, make sure that the
system is first checked and released by qualified safety personnel. The result of the test must be documented. Please read
the notes in Chapter 2, “On safety” on page 6.
Prior to releasing the machine, check whether the access to the hazardous area or the hazardous point is completely
monitored by the protective devices.
Also after approval of the machine, at regular intervals (e.g. in the morning prior to starting work) check whether the
OSSDs (on the SafeZone Mini, a safety laser scanner connected or on a safety controller) switch correctly to the OFF
state as soon as there is an object in the protective field. This test should be performed along all protective field
boundaries as per the specific regulations for the application (see Chapter 9, “Test notes” on page 47).
Power-up sequence
After power up the SafeZone Mini runs through a power up cycle. During the power up cycle, the sevensegment display

Pre-commissioning tests
The purpose of the pre-commissioning tests is to confirm the safety requirements specified in the national/international
rules and regulations (EC conformity). This applies particularly to the safety requirements in the machinery directive or
work equipment directive.
Ensure that you do not place anybody at risk during initial commissioning of the machine!
Always expect that the machine, system or the protective device does not yet behave as you have planned.
Ensure that there are no persons in the hazardous area during initial commissioning.
Rockwell Automation Publication 10000337275 Ver 01—October 201447
Page 50
Chapter 9Commissioning
Check the effectiveness of the protective device mounted to the machine, using all selectable operating modes as
specified in the checklist in the annex (see Chapter 14, “Checklist for the manufacturer” on page 70).
Ensure that the operating personnel of the machine protected by the safety laser scanner are correctly instructed by
qualifie d safety perso nnel before being allowed to operate the machine. Instructing the operating personnel is the
responsibility of the machine owner.
Ensure that the information label Important information, which is included with the safety laser scanner on
delivery, is affixed to the machine in a place where it is clearly visible for the operators. Ensure that the operators have
the possibility to perform this daily check correctly.
The annex to this document includes a checklist for review by the manufacturer and OEM. Use this checklist as a reference
before commissioning the system for the first time (see Chapter 14.2 “Checklist for the manufacturer” on page
Document the adjustment of the safety laser scanner and the results of the testing during initial commissioning in a

).
Recommendation
Note
ATTENTION
Use the Create development dump... function in the SCD software (right click on the COM interface to which the
safety laser scanner is connected). You can keep these data as a backup and in this way document the state during
initial commissioning at any time.
Your Rockwell Automation representative will be pleased to provide you with advice on initial commissioning.
Regular inspection of the protective device by qualified safety personnel
Check the system following the inspection intervals specified in the national rules and regulations. This procedure ensures
that any changes on the machine or manipulations of the protective device after the initial commissioning are detected.
If major changes have been made to the machine or the protective device, or if the safety laser scanner has been
modified or repaired, check the system again as per the checklist in the annex (see Chapter 14, “Checklist for the
manufacturer” on page 70).
Daily testing of the protective device by a specialist or authorized
personnel
The effectiveness of the protective device must be checked daily by a specialist or by authorized personnel. The test must
also be performed if the operating mode is changed.
No further operation if errors occur during the test!
If any one of the following points is not met, it is not permitted to continue to work on the machine or operate the vehicle.
In this case the installation of the SafeZone Mini must be checked by qualified safety personnel (see Chapter 9, “Regular
inspection of the protective device by qualified safety personnel” on page 48).
The test must be carried out for the relevant preset monitoring case.
Check the mechanical installation to ensure that all mounting screws are secure and that the is properly aligned
SafeZone Mini.
Check each SafeZone Mini device for visible changes such as damage, manipulation etc.
Switch on the machine/system.
Watch the LEDs on each SafeZone Mini.
If not at least one LED of each SafeZone Mini is permanently lit when the machine/system is switched on, it is to be
assumed that there is a fault in the machine or system. In this case the machine must be shut down immediately and
checked by qualified safety personnel.
Deliberately infringe the protective field while the machine is running in order to test the protective function for the
entire system. The LEDs of the SafeZone Mini must change from green to red and the dangerous movement must stop
immediately.
Repeat this test at different points in the hazardous area and on all SafeZone Mini devices. If you discover any non-
conformance of this function, the machine/system must be shut down immediately and checked by qualified safety
personnel.
For stationary applications, check that the hazardous areas marked out on the floor match the shapes of the protective
fields stored in the SafeZone Mini and that any gaps are protected by additional safe ty measures. In the case of mobile
applications, check that the moving vehicle actually stops in a timely manner at the protective field boundaries which
are set in the SafeZone Mini and listed on the information label on the vehicle or in the configuration protocol. If you
discover any non-conformance of this function, the machine/system/vehicle must be stopped immediately and
checked by qualified safety personnel.

Cleaning optics cover
Replacing the optics cover
Do not make any repairs to the device!
The SafeZone Mini does not contain any repairable components. For this reason do not open the SafeZone Mini
components and only replace the parts that are described in the following chapters as replaceable.
Switch the entire machine/system off line!
The system could inadvertently start up while you are replacing the optics cover. As a matter of principle, always isolate
the machine from the power supply during all work on the machine and safety laser scanner.
The SafeZone Mini safety laser scanner is largely maintenance-free. The optics cover on the safety laser scanner should
however be cleaned regularly and if it is contaminated.
Do not use aggressive cleaning agents.
Do not use abrasive cleaning agents.
Static charges cause dust particles to be attracted to the optics cover. You can diminish this effect by using the anti-static
Note
plastic and the lens cloth.
How to clean the optics cover:
Use a clean and soft brush to remove dust from the optics cover.
Moisten the optics cloth with the anti-static plastic cleaner and wipe off the window for light output on the optics
cover with the cloth.
ATTENTION
Notes
Perform an optics cover calibration with the aid of the SCD software after the replacement of the optics
cover!
The level of contamination is measured continuous ly during the operation of the SafeZone Mini. For this purpose the
optics cover calibration must first be performed; this then serves as a reference for the contamination measurement
(status = not contaminated).
The optics cover calibration is only allowed to be performed with a new optics cover! The new optics cover must be free of
contamination at the time of the optics cover calibration. The optics cover calibration should be performed at room
temperature [10°…30°C (50°…86° F)]!
If the optics cover is scratched or damaged, you must replace the optics cover. Order the replacement optics cover from
Rockwell Automation (see Chapter 13,“Accessories/spare parts” on page 65).
• The optics cover on the SafeZone Mini is an optical part that must not be soiled or scratched on replacement.
• The optics cover is only allowed to be replaced by qualified safety personnel in a dust and dirt-free environment.
• Never replace the optics cover during ongoing operation, as internal parts may be irreparably damaged in certain
circumstances and dust particles may enter the device.
• It is imperative that you avoid contamination of the inside, e.g. with fingerprints.
• Do not use any additional sealant for sealing the optics cover, e.g. silicon, as these substances may affect the optics.
• Use a torque wrench (universal joint) with 2.5 mm hex socket bit.
• Mount the optics cover as per the following instructions to ensure that the housing is sealed to IP 65.

The SafeZone Mini tests the OSSDs immediately after switch on and then at regular intervals. For this purpose the
SafeZone Mini briefly switches off both OSSDs (for 300 s) and checks whether the OSSDs switch to the OFF state during
this time.
Ensure that the safety inputs on the controller used do not respond to these test pulses and as a result cause the machine
or system to unintentionally shutdown!
Approximately 35 ms after the switch on of the OSSDs, the SafeZone Mini performs the first voltage test and then after a
half basic response time (40 ms) a second voltage test.

The detection capability of the warning field is dependent on the remission of the objects to be detected.
The total response time of your application is dependent on further factors.
To meet the requirements of the relevant product standards (e.g., EN 61496-1), the external voltage supply for the device must be
able to bridge a brief mains failure of 20 ms. Power supp lies according to EN 60204-1 satisfy this requirement. Suitable power
supplies are available as accessories from Rockwell Automation.
The absolute voltage level must not drop below the specified minimum voltage.
The load currents for the input capacitors are not taken into account.

Switching currents up to 500 mA are allowed briefly (100 ms).
In the case of a fault (0 V cable open ci rcuit) maximally the leakage current flows in the OSSD cable. The downstream controller must
detect this status as LOW. An FPLC (fail-safe programmable logic controller) must be able to identify this status.
Make sure to limit the individual line core resistance to the downstream controller to this value to ensure that a cross-circuit between
the outputs is safely detected. (Also note EN 60 2041.)
When active, the outputs are tested cyclically (brief LOW). When selecting the downstream co ntrollers, make sure that the test
signals do not result in deactivation.

Have measures been taken to prevent and monitor unauthorized presence in the hazardous area when
hazardous area/hazardous point protection (mechanical protection) and have these been secured
against removal?
Are additional mechanical protective measures tted and secured against manipulation, which prevent
reaching under, over, and around the ESPE?
Has the maximum stopping and/or stopping/run-down time of the machine been measured, specied
and documented (at the machine and/or in the machine documentation)?
Has the ESPE been mounted such that the required minimum distance from the nearest hazardous
point has been achieved?
Are the ESPE devices properly mounted and secured against manipulation after adjustment?
Are the required protective measures against electric shock in eect (protection class)?
Is the control switch for resetting the protective device (ESPE) or restarting the machine present and
correctly installed?
Are the outputs of the ESPE (OSSDs, ASInterface Safety at Work) integrated in compliance with the
required PL/SILCL according to EN ISO 13 8491/EN 62 061 and does the integration comply with the
circuit diagrams?

Has the protective function been checked in compliance with the test notes of this documentation?
Are the given protective functions eective at every setting of the operating mode selector switch?
Are the switching elements activated by the ESPE, e.g. contactors, valves, monitored?
Is the ESPE eective over the entire period of the dangerous state?
Once initiated, will a dangerous state be stopped when switching the ESPE on or o and when
changing the operating mode, or when switching to another protective device?
Has the information label for the daily check been attached so that it is easily visible for the operator?
Checklist for the manufacturer/installer for installing electro-sensitive protective
equipment (ESPE)
Details about the points listed below must be present at least during initial commissioning — they are, however, dependent on the
respective application, the specifcations of which are to be controlled by the manufacturer/installer.
IMPORTANT
This checklist should be retained and kept with the machine documentation to serve as reference
during recurring tests.

Restart interlock
Universal I/O
Active opto-electronic protective device responsive to diffuse reflection (e.g. SafeZone Mini, see also CLC/TS 614963)
A device that electronically monitors the relay or contactor operated by the protective device prior to each new start.
Protective fields and warning fields form the so-called field set.
Plastic part with window for light output. The optics cover is available as a spare part.
(Output signal switching device) The OSSD output is the switching output on the SafeZone Mini. This is a semiconductor
output and is periodically tested for correct function. The SafeZone Mini has two OSSD outputs that operate in parallel; for
safety reasons these must be evaluated using two channels.
The protective field secures the hazardous area on a machine or vehicle. As soon as the safety laser scanner detects an
object in the protective field, it switches the OSSDs to the OFF state and thus initiates the shutdown of the machine or stop
of the vehicle.
Reflection of luminance. A measure of the remission is the level of remission defined as the ratio of the luminance
reflected from a surface in the measuring direction and the luminance of a completely matte white surface (white
standard).
The minimum size of an object that is acquired by the protective device and is guaranteed by the manufacturer.
The restart interlock is a protective device. In certain situations it prevents the machine from automatically restarting. This
applies, e.g., after the scanner function has triggered during a dangerous machine state, after a change to the operating
mode or the method of activation of the machine, or after the change to the start control device on the machine.
The SafeZone Mini has two universal I/O connections. These two connections can be configured as inputs (e.g. for standby, EDM or reset) or as outputs (e.g. for device error, contamination or second warning field).
Warning field
The warning field is a field with a radius of up to 8 m (26.25 ft) (see Chapter 12, “Technical specifications” on page 55).
Using this field larger areas can be controlled and simple switching functions (e.g., warning functions) triggered. The
warning field is not allowed to be used for tasks related to personnel protection.
