GuardShield™ Micro 400 Safety Light Curtain User Manual
IMPORTANT
These installation instructions are designed to
address the technical personnel of the machine
manufacturer and or the installer of the safety
system regarding the proper mounting,
configuration, electrical installation,
commissioning, operation and maintenance of
the GuardShield Micro 400 safety light curtain.
These installation instructions do not provide
instruction for the operation of machinery to
which the GuardShield Micro 400 safety light
curtain is, or will be, integrated. Only qualified
personnel should install this equipment.
Introduction
The GuardShield Micro 400 is an economical three box
(transmitter, receiver and controller) Type 4 safety light curtain
offered in a small profile (15 x 20 mm (0.59 x 0.79 in.)) housing.
The protective heights are offered from 150…1200 mm
(5.9…47.24 in.) in 150 mm (5.9 in.) increments. The compact
housing size allows the GuardShield Micro 400 to be mounted in
areas where standard safety light curtains may not be able to be
mounted due to space constraints. It is also possible to recess the
GuardShield Micro 400 transmitter and receiver into machine
frames.
Micro 400 System
The Micro 400 requires a dedicated controller, either an MSR41
which has ON/OFF functionality or an MSR42 which offers
advanced functionality of fixed and floating blanking, manual
restart and muting. The MSR42 can also be used as a multi
function safety module, allowing the connection of additional
safety light curtains, safety laser scanner — any safety device with
PNP type outputs.
The Micro 400 transmitter and receiver are offered with 8-pin M12
connectors at the end of 500 mm (20 in.) integrated cables. The
patchcords to connect the transmitter and receiver to the
controller are the same part number and are offered in a variety of
lengths. These patchcords are configured on one end with M12
connectors which mate to the integrated pigtail connectors and
RJ45 connectors on the opposite end which plug into to the MSR
41 or MSR42 controllers.
Micro 400 Cascading
The GuardShield Micro 400 is also offered in a “cascadeable”
configuration. GuardShield Cascadeable Micro 400 safety light
curtains allow the interconnection of multiple segments of the
Micro 400 safety light curtain with a common pair of safety
outputs. This cascadeable configurability of the GuardShield
Micro 400 reduces overall system wiring and allows the
GuardShield Micro 400 to be fitted into a variety of applications
where the safety distances for mounting the light curtain may
allow personnel to stand between the light curtain’s sensing field
and the hazard or where multiple-sided guarding is required and
the use of corner mirrors is not possible.
A GuardShield Cascadeable Micro 400 safety light curtain system
is comprised of one or two pair of Cascadeable Micro 400 light
curtains as well as a standard Micro 400 pair as the last segment
pair in the cascaded system.
GuardShield Micro 400 cascaded pairs are offered in both 14 mm
(0.55 in.) and 30 mm (1.18 in.) resolutions in limited protected
heights. It is possible to mix 14 mm (0.55 in.) and 30 mm (1.18 in.)
resolution pairs in a Cascaded Micro 400 system.
When connecting two cascadeable segments together, the
resultant cable length between segments is 1000 mm (40 in.).
If an additional length between segment pairs is required,
Rockwell offers an M12 to M12 patchcord in 1, 3, and 5 m (3.3, 9.8,
and 16.3 ft) lengths (445L-AC8PC1 or 445L-AC8PC3).
Note: The maximum Cascaded Micro 400 system length can not
exceed 10 m (32.8 ft) as measured between the RJ45
connection at the MSR 41 or MSR 42 Controller to the last
beam in the standard Micro 400, including all cable
lengths. The maximum number of beams in a cascaded
Micro 400 system can not exceed 255 beams.
Micro 400 Washdown Option
The GuardShield Micro 400 is offered with the transmitter and
receiver sealed in clear polycarbonate tubes with an
environmental rating of IP69K. These IP69K Micro 400 light
curtains are factory sealed and are ordered as pairs. They are
offered in a 14 mm (0.55 in.) resolution in protected heights of
150, 300, 600, 900, and 1200 mm (5.9, 11.8, 23.6, 35.4, and 47.2 in.).
The required MSR41 or MSR42 controllers maintain the IP20 rating
and must be mounted in a suitable enclosure.
The Micro 400 IP69K transmitter and receiver are both offered
with
8-pin M12 connectors at the end of 500 mm (20 in.) integrated
cables. The patchcords to connect the transmitter and receiver to
the controller are the same part number and are offered in 1, 2, 3,
5, and 8m (3.3, 6.6, 9.8, 16.4, and 26.2 ft) lengths.
These patchcords are configured on one end with M12
connectors which mate to the integrated pigtail connectors and
RJ45 connectors on the opposite end which plug into to the
MSR42 or MSR41 controller.
Micro 400 Specials
In addition to the standard GuardShield Micro 400 configurations,
the GuardShield Micro 400 is also offered in special configurations
as described in the Appendix.
The GuardShield Micro 400 family of safety light curtains are
general purpose presence sensing devices, designed for use on
hazardous machinery providing point of operation (POC), as well
as, perimeter (PAC) detection.
Note: The standard GuardShield Micro 400 must always be the
last segment in a Cascaded Micro 400 system
A cascadeable pair of GuardShield Micro 400 light curtains has a
500 mm (20 in.) pigtail with a female M12 quick disconnect on the
bottom of the Micro 400 light curtain and a 500 mm (20 in.) pigtail
with a male M12 quick disconnect attached to the top of the
Micro 400 transmitter and receiver.
The GuardShield Cascadeable Micro 400 system operates as a
single light curtain pair with a common set of OSSDs. Each
segment pair is connected in series making the complete system’s
response time the sum of each segment pair, plus the response
time of the MSR41 or MSR42 and other safety devices in the stop
circuit.

Principle of Operation
The GuardShield Micro 400 safety light curtain consists of a nonmatched pair of optic units, i.e., transmitter and receiver with the
same protected height and resolution. The controller
functionality of the Micro 400 light curtains are through a
separate control module.
• MSR41 ON/OFF functionality
• MSR42 multi-function module
The maximum distance between transmitter and receiver is
referred to as the protective field width or range. The protective
field height is the distance between the first and last beam in the
device.
The transmitter emits sequential pulses of infrared light which are
received by the GuardShield Micro 400 receiver and processed by
the connected controller. The synchronization of the timing of the
emission and reception of infrared light pulses is accomplished by
the connected MSR controller.
The connected controller has safety outputs [Output Signal
Switching Devices (OSSDs)] and nonsafety auxiliary outputs.
When the GuardShield Micro 400 transmitter and receiver are
properly connected and aligned, the OSSDs of the connected
controller are current sourcing +24V DC. Interruption of the
sensing field causes the controller to switch the sourced current
OFF (0V DC).

The GuardShield, Micro 400 POC is also available in cascading
segments which allow a number of GuardShield Micro 400
transmitters and receivers to be interconnected. This product
configurability allows the GuardShield Micro 400 to protect
multiple sides of a machine or simply adds flexibility when
positioning the GuardShield Micro 400 in various applications.
Patchcords

must be a standard
Micro 400 pair
Figure 2: Up to three GuardShield Micro 400 segments can be interconnected. For limitations
see text.
Standard GuardShield Micro 400 cascading segments are offered
in protective heights from 300…1200 mm (11.8…47.2 in.) in both
14 mm (0.55 in.) and 30 mm (1.18 in.) resolutions.
A maximum of three GuardShield Micro 400 light curtains can be
interconnected (maximum two cascades plus one standard
GuardShield Micro 400). The maximum number of beams in a
cascading system is 255 beams. The individual segments can have
mixed resolutions, i.e., 14 mm and 30 mm as long as the pairs
have the same protective heights and resolutions. The maximum
cable length from the control unit to the last beam can be 10 m.
Cascading segments cannot be used as standalone light curtain
pairs.
However, if using multiple cascaded pairs or only one, the last pair
in the cascaded system must be a standard GuardShield Micro
400 light curtain.
The following limitations need to be considered:
• A maximum of 255 light beams per controller
• 10 m maximum total length for light curtains, extension
modules and connection cable combined (Figure 2)
• Only a Rockwell patchcord (445L-AC8xxx) may be used
between the light curtains and the controller. A patchcord is
required to connect the M12 connector of the Micro 400 to
either the MSR41 or MSR42 controller. The patchcord has an
8-pin M12 on one end and an RJ45 connector on opposite end.

Examples of Range of Use
The GuardShield Micro 400 safety light curtain operates as a
proper protective device only if the following conditions are met:
• The control of the machine must be electrical.
• The controlled machine must be able to be stopped any where
in the machines stroke or cycle.
• The transmitter and receiver must be mounted such that
access to the hazard is only through the light curtain’s
protective field.
• If used as an access device, the restart button must be located
outside the hazardous area such that it can not be operated by
a person working inside the hazardous area.
• The statutory and local rules and regulations must be observed
when installing and using the device.

IMPORTANT
Additional measures may be necessary to
ensure that the ESPE does not fail to danger
when other forms of light radiation are present
in a particular application (i.e., use of cableless
control devices on cranes, radiation from weld
spatter or effects from strobe lights).
The protective system must be tested for
proper operation after each and every change
to the configuration.
IMPORTANT
The response time of the GuardShield Micro 400
light curtain system is dependent on the
opera ting mode of the connected safety controller.
With the help of an optical interface (445LAF6150) it is also possible, to delay the response
time of the connected safety light curtain
system, when the GuardShield Micro 400 is
connected to the MSR42 controller.
If a controller unit is reconfigured, a new
configuration control document must be
printed and has to be kept close to the
controller. Also the corresponding control unit
has to be marked with the provided label.
IMPORTANT
When making changes to the configuration of
the GuardShield Micro 400 system, it is
necessary to recalculate the safety distance and
potentially relocate the GuardShield Micro 400
light curtains at the proper distance from the
hazard.
IMPORTANT
The device can be operated in a fixed and/or
floating blanking mode if an MSR42 controller
is used. The resolution will increase according
configuration control document. The light
curtain stick has to be clearly labeled with the
configured resolution.
Safety Functions
The GuardShield Micro 400 safety light curtain offers a variety of
functions, which are integral to the system.
Operating modes, functions and features of the GuardShield
system are activated through HW or SW of the corresponding
connected MSR41 or MSR42 controller. For details, please refer to
the manual of the attached controller.
IMPORTANT
Response Time
The standard response time of the light curtain (see MSR42)is
dependant on the physical resolution and the protective height and is
shown on the product label. The actual response time depends on
the connected control unit and its configuration. The response
time may be faster and can be taken from the corresponding
configuration control document, created from the configuration
software of the corresponding safety controller (e.g., MSR42).
The total light curtain system response time for a cascaded
system is the sum of the response times of each cascade plus the
response time of the standard light curtain. The declared
response times are worst case values.
A worst case response time is printed on the product label or in

Parameters which may lead to an increased response time:
• Stop delay time
•Blanking
•Muting
• Using an MSR45E relay expansion module
Blanking
There are some industrial applications where material must be fed
through the protective field (e.g., textile machines or small
assembly machines). This movement of material through the
GuardShield Micro 400’s sensing field in the standard safety mode
would result in an interruption and therefore bring the machine
to an unwanted stop. To avoid this it is possible to blank out
certain beams. This operating mode is generally known as “Fixed
Blanking.” Blanking functionality is available with the MSR42
controller and requires the optical interface module to program
this functionality.

With a MSR42 safety controller and an Optical Interface
(445L-AF6150) it is possible for authorized personnel to activate
different blanking modes. Blanking modes are broken down into
the following categories:
•Fixed blanking
•Floating blanking
7
GuardShield™ Micro 400 Safety Light Curtain User Manual
With the blanking function, the resolution and
the response time of the GuardShield Micro 400
light curtain system will be changed. If the
"Blanking" function is activated, a new, longer
response time and a new, larger resolution will
be present, which must be applied to the
calculation of the safety distance. The minimal
safety distance of the light curtain must always
be adapted to the actual operating mode. The
corresponding reaction time of a light curtain
without blanking is stated on the label of each
system. If blanking is configured, the new
reaction time, and the new resolution,
according to the configuration control
document must be entered in the appropriate
spaces on the supplied label, and attached to
the GuardShield Micro 400 light curtain (see
Figure 3). The labels are provided with the
GuardShield Micro 400 mounting kit.
Further information on "Blanking" may be
found in the “Configuration and Diagnostic
Tool” manual for the corresponding safety
controller (e.g. MSR42).
The GuardShield Micro 400 safety light curtains
must be mounted at a sufficient distance from
the pinch point or point of operation hazard to
ensure that the machine stops before a person’s
finger, hand, arm(s), or body reaches the hazard.
IMPORTANT
Regardless of the calculated safety distance,
GuardShield Micro 400 safety light curtains
should never be mounted closer than six inches
from the point of operation or pinch point
hazard.
IMPORTANT
Determining Stop Time: The measurement of
stopping time (Ts) must include the stopping
times of all devices in the stop circuit. Not
including all device and control system
elements when calculating Ts will result in an
inaccurate safety distance calculation.

Determining the Safety Distance
The light curtain must be mounted with proper safety distance
• From the point of danger
• From reflecting surfaces
In the United States there are two formulas that are used to
properly calculate the safety distance. The first, the OSHA formula,
is the minimum requirement for the calculation of the safety
distance. The second formula, the one recommended by Rockwell
Automation, is the ANSI formula, which incorporates additional
factors to be considered when calculating the safety distance.
OSHA Safety Distance Calculation Formula
The OSHA safety distance formula as specified in CFR Subpart O
1910.217 is as follows:
Ds = 63 X T
Ds Safety Distance in inches
63 Is the OSHA recommended hand speed constant in inches
Ts Is the total stop time of all devices in the safety circuit,
Note: The T
S
per second
measured in seconds. This value must include all
components involved in stopping the hazardous motion of
the machinery. For a mechanical power press it is the
stopping time measured at approximately the 90° position
of the crankshaft rotation.
number must include the response times of all
S
devices, including the response time of the safety light
curtain, the safety light curtain controller (if used), the
machine’s control circuit
to stop the hazardous motion of
and any other devices that react
the machinery. Not
including the response time of a device or devices in the
stop time calculation will result in insufficient safety
distance for the application. This may result in operator
injury.
US Safety Distance Formula
IMPORTANT
This distance, referred to as the safety distance, must be properly
calculated prior to determining the safety light curtain’s
protective height and mounting the light curtains on the
machine. Failure to properly calculate this safety distance may
result in operator injury.

European Safety Distance Formula
A safety distance must be maintained between the light curtain
and the point of danger. This safety distance ensures that the
point of danger can only be reached after the dangerous state of
the machine has been completely removed.
The safety distance as defined in EN ISO 13855 and EN ISO 13857
depends on:
• 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 protective device, e.g. GuardShield Micro
400 (for “Response Time” see page 7).
• Reach or approach speed.
• Resolution of the light curtain and/or beam separation.
Figure 4: Safety distance from the point of danger
How to Calculate the Safety Distance S
According to EN ISO 13855 and EN ISO 13857:
-> First, calculate S using the following formula:
S = 2000 × T + 8 × (d – 14) [mm]
Where…
T = stopping/run-down time of the machine
+ response time of the protective device [s]
d = resolution of the light curtain [mm]
S = safety distance [mm]
The reach/approach speed is already included in the
formula.
-> If the result S is <= 500 mm (19.6 in.), then use the determined
value as the safety distance.
-> If the result S is > 500 mm (19.6 in.), then recalculate S as
follows:
S = 1600 × T + 8 × (d – 14) [mm]
Example:
Stopping/run-down time of the machine = 290 ms
Response time = 30 ms
Resolution of the light curtain = 14 mm (0.55 in.)
T = 290 ms + 30 ms = 320 ms = 0.32 s
S = 2000 × 0.32 + 8 × (14 – 14) = 640 mm (25.1 in.)
S > 500 mm (19.6 in.) therefore:
S = 1600 × 0.32 + 8 × (14 – 14) = 512 mm (20.1 in.)
Minimum Distance from Reflecting Surfaces
The infrared light from the transmitter may be reflected off of
shiny surfaces and be received by the system’s receiver. If this
condition occurs, it can result in an object not being detected
when it enters the GuardShield Micro 400 sensing field.
All reflecting surfaces and objects (e.g. material bins) must
therefore be located at a minimum distance a from the protective
field of the system. The minimum distance a depends on the
distance D between transmitter and receiver.

Installation and Alignment Procedure
Standard GuardShield Micro 400
The alignment procedure can be made easier with the use of integrated
indicator LEDs (Table 1).
1. Mount the transmitter and receiver with the brackets (Figure 9). Make
sure that the longitudinal axis of both are oriented parallel to each other.
For a vertical or horizontal mounting a level might help to find the
correct position.
2. Take care that the receiver and transmitter are oriented in the
same direction. This means, the beginning of the protective field
which is found next to the cable which leads to the safety
controller, must be located at the same end of the protective
field. A reference would be that the indicator LEDs are opposite
one another. It is not allowed to mount the GuardShield Micro
400 systems rotated 180° (Figure 8: Layout of the transmitter/
receiver).
3. Connect the transmitter and receiver to the controller and
power up according the description in the following section.
The indicators will help for alignment.
4. After aligning the longitudinal axis of the transmitter and
receiver, rotate the receiver along the longitudinal axis to find
the receiving angle. During rotation, the receiving angle is
shown by the illumination of the green LED in the GuardShield
Micro 400 light curtain. If this green LED is blinking, the amount
of light detected by the receiver is not sufficient for stable
operation. After realigning the light curtain, the protective field
must be briefly interrupted. After removing the object from the
protective field, a sufficient intensity level is indicated by the
illumination of the green LED in the light curtain.
5. Adjust and mount the receiver at the center of this operating
angle.
6. After aligning the receiver, rotate the transmitter to find the
transmitting angle. During rotation, the transmitting angle is
shown by the illumination of the green LED in the GuardShield
Micro 400 light curtain.
7. Adjust and mount the transmitter at the center of this
operating angle.
8. Test the protective function of the GuardShield Micro 400 light
curtain by using the test rod, according to Figure 13. The
insertion of this rod into the protective field at any position has
to lead to a protective field interruption (illumination of the red
LED in the GuardShield Micro 400).

When two or more GuardShield Micro 400s are mounted in close
proximity to one another, it may be possible for the receiver of
one GuardShield Micro 400 pair to receive infrared light from the
transmitter of another GuardShield Micro 400 pair.
There are various techniques to prevent or eliminate the
possibility of optical interference from light curtains mounted in
the same plane. The simplest method is to alternate transmitter
and receiver pairs so that the receiver from a second pair is facing
away from the transmitter of another light curtain pair in close
proximity. It is also possible to place a physical barrier between
pairs to prevent the infrared light from reaching another light
curtain pair.

Two Segment Cascading GuardShield Systems
When the safety distance calculation requires that a GuardShield
pair is vertically mounted at a distance that would allow a person
to stand between the vertical pair and the machine hazard, a
means of detection of that person is required.
There are a few methods of detecting the presence of a person
who could be standing in front of the machine hazard but inside
of the light curtain; installing a safety mat or safety laser scanner
are possible solutions, however, they are costly solutions as these
are separate safety systems that need to be integrated to the
safety circuit. The most cost-effective solution is to interconnect
an additional light curtain in series to the vertical pair. This is
accomplished by first selecting a cascading pair of GuardShield
Micro 400 safety light curtains with a protective height and
resolution based upon the results of a risk assessment. It is then
necessary to select the horizontal protected height of the pair of
GuardShield Micro 400 light curtains. This pair should provide
detection from the vertical pair to the front of the machine
hazard. In most cases this pair of GuardShield Micro 400 can be 30
mm resolution as their purpose is to detect the presence of a
person, not a person’s fingers or hands.
The next step is to select the interconnect patchcords for the
transmitter and receiver. These patchcords are offered in a variety
of lengths (“Table 6: Available cable types” on page 14). The final
cascading segment which is not connected to another pair of
Figure 11: Top and bottom mounting of three GuardShield Micro 400 segments is possible,
which will provide three-sided machine guarding without the use of corner mirrors

It helps to align the cascading segments in a
particular order. First connect the last segment
(segment with one connector) closest to the
control unit. Once the LED in the edge is green;
secure mounting brackets of that pair. Next
connect middle segment to the last segment
and connect to the controller. When middle
segment receiver LED is green secure those
brackets. Finally connect the closest segment to
the other segments and connect all together to
the controller.
Only the diagnosis LED of the first segment
displays the protective field status. The LEDs of
other segments stay off.
For aligning a cascaded system, the optical
interface module (see “Accessorie” on page 25)
can be a valuable alignment help.
IMPORTANT
Do not rotate end or connection cap as there’s a
danger of bending the light curtain.
Do not mount brackets on transparent tube.
Excessive force may damage the tube. When
using cleaning solutions, consider the materials
listed in Table 3.

Electrical Installation
Connections
The connection of a GuardShield Micro 400 to a machine
controller must occur using an MSR41 or MSR42 Series safety
controller module. Only prefabricated cable (445L-AC8xxx)
provided by Rockwell Automation may be used between the light
curtain and controller (Table 5).
The Micro 400 requires two patchcords, one for the transmitter
and one for the receiver. The M12 8-pin connector is used for
connecting to the light curtain, while the RJ45 connector is
plugged to the controller. M12 to M12 patchcords are used for
extending the cable, especially between cascades of the Micro
400 light curtain.

Power supply, inputs, safety outputs and status outputs are
connected to the terminal block of the MSR41, MSR42 controller
or a MSR45E (see wiring diagrams, figures 14 and 15 on page 15).
The interfacing of the light curtain with the machine control has
to be control reliable, i.e. a correct interface with a safety PLC or
safety relays with positive guided relay contacts.

External test signal
In case the risk analysis of the application requires an external test
signal (according to EN 13849-1) please refer to the user manual
of the connected MSR42 control unit.
Power supply
The power supply and the evaluation of the protective field of a
GuardShield Micro 400 light curtain can only be carried out
through a MSR41 or MSR42 Series control unit.
Bringing into operation
The transmitter and receiver units must be connected to a MSR41 o r
MSR42 safety control unit. Then the supply voltage may be
connected to the control unit. After power-up, there is an automatic
self test (duration < 5 s) of all system components.
In case the protective field is free and the transmitter and receiver
are correctly aligned, the green LEDs on the GuardShield Micro
400 light curtains will illuminate.
If after a successful power-up the light curtain detects an
interruption of the protection field, the red LEDs on the
GuardShield Micro 400 light curtains will illuminate.
M
more MSR45E safety relay expansion modules can be connected
to the MSR41 or MSR42 controller.
Each MSR41 or MSR42 safety controller also provides two status
outputs (Info1 and Info2). These may only be connected to the
machine controller for information purposes.
ATTENTION
Outputs
A GuardShield Micro 400 safety light curtain pair is always
connected to a safety controller. Every connection to a machine
controller or a safety circuit is done through an MSR41 or MSR42
safety controller, which provides two redundant semiconductor
OSSD (Output Signal Switching Device) safety outputs. One or

ATTENTION
Prior to first powering up or after a changed
machine setting, the responsible person shall
review the following checklist.
Checklist
Before the initiation of the GuardShield Micro 400 the responsible
person should work through the following checklist.
Check prior to first initiation or after a changed machine setting (e.g.,
a rewiring):
1. The power supply is a 24V DC device, that must comply to all
applicable standards of the Machinery Directive 2006/42/EC,
and the product standard (IEC61496), for example 1606-XLPseries. No connection to a conventional power supply.
2. Proper polarity of the power supply at the controller of the
GuardShield Micro 400.
3. The transmitter connection cable is properly connected to the
transmitter, the receiver connection cable is properly
connected to the receiver. All plugs are connected.
4. The OSSD outputs are not connected to +24V DC.
5. The connected switching elements (load) are not connected to
24V DC.
6. If two or more GuardShield Micro 400s are to be used, make
sure that each system is properly installed, in order to avoid
optical interference.
Switch the GuardShield Micro 400 on and check its function by
observing the following: two seconds after switching on, the
system starts to work properly if the protection field is free of
obstructions
Troubleshooting
With the help of two LEDs, system conditions and faults of the
GuardShield Micro 400 systems are indicated.
A red and a green LED are integrated in the end-cap connection
module of each profile (near the cable), which clearly signals the
sta tus o f the protective fie ld. With the help of the LED display, system
conditions and faults of the GuardShield Micro 400 systems are

Special systems
In addition to the GuardShield Micro 400 manual this appendix
gives some additional information for some GuardShield Micro
400 special systems.
Systems with Re-inforced Profiles
The GuardShield Micro 400 standard safety light curtains are
usually offered in the slim profile with dimensions of 20 x 15 mm.
The maximum length is limited to 1200 mm (47.2 in.) to prevent a
damage by twisting or bending. For longer lengths up to 2200
mm the systems are offered in a re-inforced profile. Standard and
cascaded systems are available based on the re-inforced profile.

Figure 22: Cross section of the re-inforced profile
Two kits required per pair.
Perimeter Systems (PAC)
Perimeter systems are usually produced by means of several
single beam light barriers. But the flexibility of the GuardShield
Micro 400 system allows also the production of vertical entry
safeguarding according to the standard EN ISO 13855 [2010].
Such systems are composed of active and passive elements in one
compact profile. The element length of each is 50 mm (1.97 in.)
(variations are given in the appendix).
The big advantage of GuardShield Micro 400 Perimeter systems is
the easier way of mounting and the uncomplicated way of
starting up the operation. The time needed to connect the wires
and aligning the optics is reduced in comparison to standard
perimeter systems consisting of single beam light barriers, where
often mirrors are also included which can only be positioned with
difficulties.
The protective field and the active elements, respectively, are
clearly recognized as surfaces with the integrated optical lenses.
The not monitored areas (passive elements) are also clearly
indicated as black surfaces.
How to Calculate the Safety Distance S for
GuardShield Micro 400 PAC Systems
In the case of perimeter systems or light curtains with a resolution
d > 40 mm, the safety distance is calculated for vertical mounting
light curtains and horizontal approach, according to the formula:
S = 1.6 mm/ms x T + 850 mm
More detailed information regarding safety distance and safety
heights can be found in standard EN 13855 (2010).

Special Systems
Besides the standard lengths given in “Technical Specifications”
on page 20 Rockwell Automation also offers some special lengths
and configurations. For those systems, longer lead time might be
expected.
The mentioned response times (*) are maximum values. The times
depend on the controller type and the configuration. The real
response time may be faster. Please obtain the exact response
time from the MSR42 "Configuration software."
