2 Safety
For mounting, operating and testing, this document as well as all applicable national and international stan-
dards, regulations, rules and directives must be observed. Relevant and supplied documents must be ob-
served, printed out and handed to affected persons.
ÄBefore working with the safety sensor, completely read and observe the documents applicable to your
task.
In particular, the following national and international legal regulations apply for the commissioning, techni-
cal inspections and work with safety sensors:
• Machinery directive 2006/42/EC
• Low voltage directive 2014/35/EU
• EMC directive 2014/30/EU
• Use of work equipment directive 89/655/EEC supplemented by directive 95/63EC
• OSHA 1910 Subpart O
• Safety regulations
• Accident-prevention regulations and safety rules
• Ordinance on Industrial Safety and Health and employment protection act
• Product Safety Law (ProdSG and 9. ProdSV)
NOTICE
For safety-related information you may also contact local authorities (e.g., industrial inspec-
torate, employer's liability insurance association, labor inspectorate, occupational safety and
health authority).
2.1 Intended use and foreseeable misuse
WARNING
A running machine may result in serious injury!
ÄMake certain that the safety sensor is correctly connected and that the protective function of
the protective device is ensured.
ÄMake certain that, during all conversions, maintenance work and inspections, the system is
securely shut down and protected against being restarted.
2.1.1 Intended use
• The safety sensor may only be used after it has been selected in accordance with the respectively ap-
plicable instructions and relevant standards, rules and regulations regarding labor protection and safety
at work, and after it has been installed on the machine, connected, commissioned, and checked by a
competent person (see chapter 2.2 "Necessary competencies"). The devices are designed for indoor
use only.
• When selecting the safety sensor it must be ensured that its safety-related capability meets or exceeds
the required performance level PLr ascertained in the risk assessment (see chapter 14.1 "General
specifications").
• The safety sensor protects persons or body parts at points of operation, danger zones or access points
of machines and systems.
• With the “access guarding” function, the safety sensor detects persons only when they enter the danger
zone but cannot tell whether there are any persons inside the danger zone. For this reason, a start/
restart interlock or a suitable stepping behind protection in the safety chain is essential in this case.
• The construction of the safety sensor must not be altered. When manipulating the safety sensor, the
protective function is no longer guaranteed. Manipulating the safety sensor also voids all warranty
claims against the manufacturer of the safety sensor.
• The safety sensor must be inspected regularly by a competent person to ensure proper integration and
mounting (see chapter 2.2 "Necessary competencies").
• The safety sensor must be exchanged after a maximum of 20 years. Repairs or the exchange of wear
parts do not extend the mission time.

Protective field properties
The beam distance and the number of beams are dependent on the resolution and protective field height.
NOTICE
Depending on the resolution, the effective protective field height can be larger than the optically
active area of the safety sensor housed in yellow (see chapter 3.1 "Device overview of the MLC
family" and see chapter 14.1 "General specifications").
Device synchronization
The synchronization of receiver and transmitter for creating a functioning protective field is done optically,
i.e. without cables, via two specially coded synchronization beams. A cycle (i.e. a pass from the first to the
last beam) is called a scan. The length of a scan determines the length of the response time and affects the
calculation of the safety distance (see chapter 6.1.1 "Calculation of safety distanceS").
NOTICE
For the correct synchronization and function of the safety sensor, at least one of the two syn-
chronization beams must be free during synchronization and operation.

QR code
A QR code as well as the corresponding web address are located on the safety sensor.
At the web address, you will find device information and error messages after scanning the QR code with a
mobile end device or after entering the web address.
When using mobile end devices, mobile service charges can accrue.
Fig.3.2: QR code with corresponding web address (URL) on the safety sensor
3.2 Connection technology
The transmitter and receiver feature an M12 connector as an interface to the machine control with the fol-
lowing number of pins:
Device model Device type Device plug
MLC 500/A AS-i transmitter 5-pin
MLC 510/A Basic AS-i receiver 5-pin
Host devices are also equipped with an interconnection cable, 400mm long, with M12 connector for con-
necting MiddleGuest or Guest devices.
MiddleGuest devices are equipped with two interconnection cables, 400mm long, with M12 connector for
connecting Host or Guest devices.
Guest devices are equipped with an interconnection cable, 400mm long, with M12 connector for connect-
ing Host or MiddleGuest devices.
3.2.1 AS-i parameter port
The parameter port can only be addressed by the bus master. The MLC 510/A receiver delivers a safety at
work-specific code sequence which the AS-i safety monitor teaches in and permanently monitors. Further-
more, the bus master is able to read the interfering signal via the parameter port.
3.3 Cascading
To implement linked protective fields, up to three MLC safety light curtains can be cascaded one after the
other.
Adjacent protective fields, e.g., for stepping behind protection, can thereby be implemented without any ad-
ditional expense for control and connection. The host system performs all necessary processor tasks, pro-
vides indicators and the receiver-side interfaces to the machine and command devices.
Devices with different resolutions can be combined.
With mounting brackets (see chapter 15 "Ordering information and accessories"), an L or U-shaped fixed
connection can be created.

NOTICE
With permanently connected devices the resolution at the intersection point can be greater than
the resolution of the individual devices.
The operating range of the total system is defined by the component with the shortest operating
range.
To operate a Host device without connected Guest devices, a terminating plug is required (see
chapter 15 "Ordering information and accessories").
NOTICE
The total number of beams for a Host–Guest or Host–MiddleGuest guest system must
not exceed the value 400!
ÄThe number of beams for a Host–Guest or Host–MiddleGuest guest system is determined
by adding the number of beams of the individual devices (see chapter 14.2 "Dimensions,
weight, response time").
3.4 Display elements

tion” (see chapter 3.1 "Device overview of the MLC family").

Applications
Leuze electronic MLC 510 AS-i Host/Guest 17
5 Applications
The safety sensor only creates square protective fields.
5.1 Point of operation guarding
Point of operation guarding for hand and finger protection is typically the most common application for this
safety sensor. In accordance with ENISO13855, resolutions from 14to40mm make sense here. This
yields the necessary safety distance, among others (see chapter 6.1.1 "Calculation of safety distanceS").
Fig.5.1: Point of operation guarding protects reaching into the danger zone, e.g. for cartoners or filling systems
Fig.5.2: Point of operation guarding protects reaching into the danger zone, e.g. for a pick&place robot applica-
tion

Applications
Leuze electronic MLC 510 AS-i Host/Guest 18
5.2 Access guarding
Safety sensors with up to 90mm resolution are used for access guarding into danger zones. They detect
people only upon entry into the danger zone, i.e., they do not detect parts of a person or whether a person
is present in the danger zone.
Fig.5.3: Access guarding on a transfer path
5.3 Danger zone guarding
Safety light curtains can be used in horizontal arrangement for danger zone guarding - either as stand-
alone device for presence monitoring or as stepping behind protection for presence monitoring e.g. in com-
bination with a vertically-arranged safety sensor. Depending on the mounting height, resolutions of
40or90mm are used (Link destination: order guide and accessories).

Mounting
Leuze electronic MLC 510 AS-i Host/Guest 19
6 Mounting
WARNING
Improper mounting may result in serious injury!
The protective function of the safety sensor is only ensured if appropriately and professionally
mounted for the respective, intended area of application.
ÄOnly allow the safety sensor to be installed by qualified persons (see chapter 2.2 "Neces-
sary competencies").
ÄMaintain the necessary safety distances (see chapter 6.1.1 "Calculation of safety dis-
tanceS").
ÄMake sure that stepping behind, crawling under or stepping over the protective device is reli-
ably ruled out and reaching under, over or around is taken into account in the safety dis-
tance, if applicable with additional distanceCRO corresponding to ENISO13855.
ÄTake measures to prevent that the safety sensor can be used to gain access to the danger
zone, e.g. by stepping or climbing into it.
ÄObserve the relevant standards, regulations and these instructions.
ÄClean the transmitter and receiver at regular intervals: environmental conditions (see chap-
ter 14 "Technical data"), care (see chapter 10 "Maintenance").
ÄAfter mounting, check the safety sensor for proper function.
6.1 Arrangement of transmitter and receiver
Optical protective devices can only perform their protective function if they are mounted with adequate
safety distance. When mounting, all delay times must be taken into account, such as the response times of
the safety sensor and control elements as well as the stopping time of the machine, among others.
The following standards specify calculation formulas:
• IEC61496-2, "Active optoelectronic protective devices": distance of the reflecting surfaces/deflecting
mirrors
• EN13855, "Safety of machines - The positioning of protective equipment in respect of approach
speeds of parts of the human body": mounting situation and safety distances
NOTICE
In accordance with ISO13855, with a vertical protective field, it is possible to pass under beams
over 300mm or pass over beams under 900mm. If the protective field is horizontal, climbing on
the safety sensor must be prevented through suitable installation or with covers and the like.
6.1.1 Calculation of safety distanceS
General formula for calculating the safety distanceS of an Optoelectronic Protective Device acc. to
ENISO13855
S [mm] = Safety distance
K [mm/s] = Approach speed
T [s] = Total time of the delay, sum from (ta+ti+tm)
ta[s] = Response time of the protective device
ti[s] = Response time of the safety relay
tm[s] = Stopping time of the machine
C [mm] = Additional distance to the safety distance

Mounting
Leuze electronic MLC 510 AS-i Host/Guest 20
NOTICE
If longer stopping times are determined during regular inspections, an appropriate additional
time must be added to tm.
6.1.2 Calculation of safety distance if protective fields act orthogonally to the approach direction
With vertical protective fields, ENISO13855 differentiates between
• SRT: safety distance concerning access through the protective field
• SRO: safety distance concerning access over the protective field
The two values are distinguished by the way additional distanceC is determined:
• CRT: from a calculation formula or as a constant (see chapter 6.1.1 "Calculation of safety distanceS")
• CRO: from the following table “Reaching over the vertical protective field of electro-sensitive protective
equipment (excerpt from ENISO13855)”
The larger of the two values SRT and SRO is to be used.
Calculation of safety distanceSRT acc. to ENISO13855 when access occurs through the protective
field:
Calculation of safety distanceSRT for point of operation guarding
SRT [mm] = Safety distance
K [mm/s] = Approach speed for point of operation guarding with approach reaction and normal approach di-
rection to the protective field (resolution 14to40mm): 2000mm/s or 1600mm/s, when
SRT>500mm
T [s] = Total time of the delay, sum from (ta+ti+tm)
ta[s] = Response time of the protective device
ti[s] = Response time of the safety relay
tm[s] = Stopping time of the machine
CRT [mm] = Additional distance for point of operation guarding with approach reaction with resolutions of
14to40mm, d=resolution of protective device CRT=8×(d-14)mm
Calculation example
The feeding-in area in a press with a stopping time (including press Safety PLC) of 190ms is to be safe-
guarded with a safety light curtain with 20mm of resolution and 1200mm of protective field height. The
safety light curtain has a response time of 22ms.
ÄCalculate safety distanceSRT using the formula acc. to ENISO13855.
K [mm/s] = 2000
T [s] = (0.022+0.190)
CRT [mm] = 8×(20-14)
SRT [mm] = 2000mm/s×0.212s+48mm
S RT [mm] = 472
SRT is smaller than 500mm; this is why the calculation may not be repeated with 1600mm/s.
NOTICE
Implement the stepping behind protection required here, e.g., through the use of an additional or
cascaded safety sensor for area protection.
