Please read this chapter carefully before working with the M4000 multiple light beam
safety device or with the machine protected by the M4000 multiple light beam safety
device.
2.1 Qualified safety personnel
The M4000 multiple light beam safety device must only be installed, commissioned and
serviced by qualified safety personnel. Qualified safety personnel are defined as persons
who
have undergone the appropriate technical training
and
who have been instructed by the responsible machine operator in the operation of the
machine and the current valid safety guidelines
and
who have access to these operating instructions.
WARNING
2.2 Applications of the device
The M4000 system is a type 4 electro-sensitive protective equipment (ESPE) as defined by
IEC 61496E1 and IEC 61496E2 and is therefore allowed for use with controls in category 4
according to EN ISO 13849E1. The preconfiguration of the M4000 multiple light beam
safety device is suitable for:
hazardous area protection
access protection
The multiple light beam safety devices must be installed such that the hazardous area can
only be reached by interrupting the light path between sender and receiver. It must not be
possible to start the plant/system as long as personnel are within the hazardous area.
The M4000 system is intended only for use in industrial environments. When used in resi-
dential areas it can cause interference.
Refer to page 16 for an illustration of the protection modes and an example application.
Only use the multiple light beam safety device as an indirect protective measure!
An opto-electronic protective device provides indirect protection, e.g. by switching off the
power at the source of the hazard. It cannot provide protection from parts thrown out, nor
from emitted radiation. Transparent objects are not detected.
Depending on the application, mechanical protective devices may be required in addition
he M4000 system must be used only as defined in chapter 2.2 “Applications of the
T
device”. It must be used only by qualified personnel and only on the machine where it has
been installed and initialised by qualified safety personnel in accordance with these
operating instructions.
All warranty claims against SICK AG are forfeited in the case of any other use, or altera-
tions being made to the system, even as part of their mounting or installation.

ing, use and periodic technical inspections of the multiple light beam safety device, in
particular …
– Machinery Directive
– Work Equipment Directive
– the work safety regulations/safety rules
– other relevant safety regulations.
Manufacturers and operators of the machine on which the multiple light beam safety
device is used are responsible for obtaining and observing all applicable safety regula-
tions and rules.
The notices, in particular the test regulations (see “Test notes” on page 100) of these
operating instructions (e.g. on use, mounting, installation or integration into the existing
machine controller) must be observed.
Changes to the configuration of the devices can degrade the protective function. After
every change to the configuration you must therefore check the effectiveness of the
protective device.
The person who makes the change is also responsible for the correct protective function
of the device. When making configuration changes, please always use the password
hierarchy provided by SICK to ensure that only authorised persons make changes to the
configuration. The SICK service team is available to provide assistance if required.

Information on the individual materials in the M4000 is given in chapter 13 “Technical
specifications” on page 113.
2.5.2 Separation of materials
Only appropriately trained personnel are allowed to separate materials!
Caution is required when dismantling devices. There is a risk of injuries.
by components
Before you send the devices for appropriate recycling, it is necessary to separate the
different materials in the M4000.
Separate the housing from the rest of the parts (in particular the circuit board).
Send the separated parts for recycling as appropriate (see Tab. 1).
3.2.1 The principle of the multiple light beam safety device
The M4000 multiple light beam safety device secures the access to a hazardous area and
signals the entry of objects as soon as a light beam is interrupted. The machine or plant
controller that evaluates this message must then bring the dangerous movement to a halt.
You can secure two sides of a hazardous area by using a deflector mirror, with two deflec-
or mirrors you can secure three sides (see chapter 3.3.2 “Access protection on several
t
sides with the aid of deflector mirrors” on page 17ff).

the M4000 Advanced A/P
sender and receiver
M4000 Advanced A/P and M4000 Passive
(deflector unit)
The M4000 multiple light beam safety device consists of a sender unit and a receiver unit.
A distinction should be made between active/active systems and active/passive systems:
On the active/active system, sender unit and receiver unit are in separate housings, the
sender and the receiver. The light beam is emitted from the sender and is incident to
the receiver.
On the active/passive system, sender unit and receiver unit are in a common housing
(M4000 Advanced A/P). The light beam is emitted from the sender unit and is deflected
by the deflector unit M4000 Passive (mirror deflection or fibre-optic deflection) by 180°
back to the receiver unit (see Fig. 2). As a passive element, the deflector unit does not
require any electrical connections.
For the exact number and distance of beams, please see chapter 13.3 “Dimensional
drawings” on page 120ff.
The dimension of the light path between sender and receiver (or between the M4000
Advanced A/P and M4000 Passive) must not exceed the maximum permissible scanning
range (see “Technical specifications” on page 113ff.).
On active/active systems, sender unit and receiver unit synchronise automatically by
optical means. An electrical connection between both components is not required.
The M4000 is modular in structure. All optical and electronic components and assemblies
are housed in a slim and torsionally rigid housing.
The M4000 Advanced multiple light beam safety device is available with 2, 3 or 4 beams.
Other configurations with up to 12 beams are possible on request. The maximum scanning
range (dimension of the light path between sender and receiver) is 70 m.
M4000 Advanced A/P
The M4000 Advanced A/P is available with 2 or 4 beams. The maximum scanning range
(dimension of the light path between the M4000 Advanced A/P and the M4000 Passive) is
dependent of the number of beams as well as the utilized M4000 Passive and is 7.5 m
max.
M4000 Area 60/80
The M4000 Area 60/80 multiple light beam safety device is available with a monitored
area length from 300/600 mm to 1800 mm. The beam separation is 50 or 57 mm (resolution of 60 or 80 mm). The maximum scanning range is 19 m (M4000 Area 60) or 70 m
(M4000 Area 80).

uting temporarily mutes the protection provided by a safety device. In this way it is possi-
M
ble to move material to or from a machine without the need to interrupt the work process.
During muting a differentiation is made between people and material with the aid of addi-
tional sensor signals. In the event of a valid muting condition the protective device is overridden on the basis of a logical evaluation of these external sensor signals so that the ma-
terial to be transported can pass through the protective device. As soon as anything other
than material enters the hazardous area, the work process is interrupted.
Fig. 14: Schematic
illustration of muting
In the example, the material moves from left to right on a conveyor belt . As soon as the
muting sensors A1 and A2 are activated , the protection provided by the ESPE protective
device is muted and the material can move into the hazardous area. As soon as the
muting sensors are clear again , the protection provided by the protective device is reactivated.
4.1.1 Muting cycle
The muting cycle is the defined sequence of all processes that take place during muting.
The cycle starts when the first muting sensor is activated. The cycle ends when the last
muting sensor returns to its initial state (e.g. clear light path for optical sensors). Only then
is it possible to activate muting again.
Material can be transported several times during a muting cycle, if the muting condition is
maintained continuously, i.e. at least one pair of sensors remains activated continuously.
Exception: With the Exit monitoring function activated (see sections 4.2.3 and 4.2.4 from
page 30), multiple material transport within a muting cycle is not possible.
Muting sensors detect material and supply the signals which an evaluation unit requires
for the logic operation.
Sensor signals can be generated by the following external sensors:
optical sensors
inductive sensors
mechanical switches
controller signals
SICK muting sensors
Recommendation
A selection of optical muting sensors is given in the following. Depending on the type (lightswitching or dark-switching), you can use these as testable or non-testable sensors.
Note
You can use testable muting sensors in conjunction with the UE403 safety relay or a
sens:Control device. For this purpose, the sensor test function of the M4000 multiple light
beam safety device must be configured (see section 6.2 “Sensor test” on page 50ff.).

For the selection and settings for the SICK optical muting sensors in muting applications,
the following applies:
Outputs must be PNP switching.
Other series are possible.
Pay attention to the output signals in chapter 6.2.
To signal muting, the use of a muting lamp or a muting status signal is stipulated. The
muting lamp signals the temporary muting. You can use an external lamp (monitored/not
onitored) or the integrated LED on the M4000 Advanced multiple light beam safety

5.1 Restart interlock
The dangerous state of the machine is interrupted if the light path is broken , and is
not re-enabled until the operator presses the reset button situated outside the hazardous area.
Do not confuse the restart interlock with the start interlock on the machine. The start
interlock prevents the machine starting after switching on. The restart interlock prevents
the machine starting again after an error or an interruption in the light path.
You can prevent the machine restarting in two ways:
With the internal restart interlock of the M4000:

its protective function by the beams from the neighbouring system and so change to the

Notes
Beam coding increases the availability of the protected machine. Beam coding also
enhances the resistance to optical interference such as weld sparks or similar.
Within a system you must configure the beam coding for every device (sender and
receiver) separately.
After switching on, the 7Esegment display of sender and receiver will briefly display the

6.1 Number of muting sensors
To realise muting, two to four sensors can be connected. The number of sensors is defined
by the geometry of the object to be detected.
You can use the following sensor combinations:
two sensors (one sensor pair)
two sensors (one sensor pair) and an additional signal C1

– two sensors (one sensor pairs) and one additional signal C1 at the side of the

four sensors (two sensor pairs)
four sensors (two sensor pairs) and an additional signal C1
Electrical connection of muting sensors is described in the chapter “Electrical Installation”

You define the number of muting sensors by allocating the muting sensors to the related
connection using drag and drop. Device symbol M4000 Advanced (receiver) or M4000
Advanced (A/P), context menu Open device window, parameter node I/O configuration.
You can also connect an additional signal C1 to the muting sensors. The signal can be a
ontrol signal from a PLC or a further sensor. The additional signal C1 is not allowed to be
c
a static signal. It is checked for dynamic behaviour during the muting cycle. If dynamic signal behaviour is not detected, no further muting can be initiated.
The following dynamic sequence must be present at the input:
Fig. 26: Signal sequence with

Notes
To activate muting, a LOW/HIGH signal change must occur on input C1, before both mu-
ting sensors in the first sensor pair (e.g. A1 and A2) are active. If this is not the case,
then muting is not initiated.
If muting has been initiated, then a HIGH/LOW signal change must then occur on input
C1. If this is not the case, muting cannot be initiated again.
If you activate the additional signal C1, the direction detection function is activated
automatically and cannot be deactivated.
Information on the possible combinations of additional signal C1 and on connection can
be found in section 6.10 “Combinable muting functions and facilities for connecting”

tion with the UE403 and is only performed when the sensor test function has been
configured.
You can usefully increase safety with testable and non-testable sensors by using the
configurable functions (e.g. time monitors, direction detection, sequence monitoring).
To ensure that a sensor is connected and functioning, the system sends a short test signal
(LOW signal) to the sensor when the muting sensor is activated and waits for its reply
(HIGH signal on the output). The test pulse lasts 30 ms and does not affect the muting
function.

Muting ends if a sensor in the last sensor pair becomes inactive and as a result a valid
muting condition is not met. The End of muting by ESPE function shortens the duration of
uting to the time at which the ESPE light path becomes clear again. In this way you will

achieve a shorter muting time and at the same time, a high level of safety.
Notes
Note
Without the End of muting by ESPE function, muting is only brought to an end when a
sensor in the last sensor pair becomes clear again (see in Fig. 28).
With the End of muting by ESPE function, muting is brought to an end when the ESPE
becomes clear again (see in Fig. 28).
Material and means of transport must be detected by the muting sensors or the ESPE
over their entire length. There must not be any detectable gaps as otherwise muting will
be brought to an end prematurely.
If the ESPE does not always accurately detect the end of muting due to irregularities of
the material or means of transport, plant availability can be increased by configuring a
muting end delay of up to 1000 ms in the EDS.
If the ESPE’s light path does not become clear again, muting will be brought to an end
at the latest when the muting condition is no longer met.

Recommendations
You must place the muting sensors such that the entire length of both the material and
the means of transport is detected by sensors or the ESPE. There must not be any
detectable gaps as otherwise muting will be brought to an end prematurely (reduced
system availability).
The End of muting by ESPE function shortens the duration of muting to the time at
which the ESPE light path becomes clear again. In this way you will achieve a shorter
muting time and at the same time, a higher level of safety.
If the ESPE does not always accurately detect the end of muting due to irregularities of
the material or means of transport, plant availability can be increased by configuring a
muting end delay of up to 1000 ms in the EDS.
If you activate the Exit monitoring function, you must either activate the End of muting
by ESPE function or configure the Total muting time.

uting mutes the ESPE on the presence of a valid muting condition. With the Partial blank-
M
ing function, safety can be increased by only blanking part of the ESPE on the presence of
a valid muting condition. One or more light beams remain permanently active.
Fig. 31: Principle of operation
of the partial blanking
function
The part of the ESPE configured by the partial blanking function is blanked on the presence of a valid muting condition (e.g. for a specific object height). The rest of the light
beams remain active; an interruption to the light beams in the active area always results in
the shutdown of the OSSDs.
The area to be blanked is configured by entering the start of the blanking (see Fig. 32: first
beam adjacent to display or first beam remote from display ) and the number of
blanked beams.
Fig. 32: Start of the blanking
Notes
Even if partial blanking is configured, the active light beams can be muted by an over-
ride.
Monitoring of total muting time is also active during partial blanking (see section 6.3.2
on page 51).
The partial blanking is not signalled by the muting lamp.

f partial blanking is configured, this function makes it possible to switch between partial
I
blanking and muting. To ensure that an incorrect signal does not trigger invalid changeover from the partial blanking function to the muting function, it is checked whether a valid
condition for changeover is present with the aid of the additional signal C1 (dynamic sequence) (see section “Additional signal C1” on page 49).
A changeover is only sensible if, e.g., different material heights are transported at irregular
intervals and some beams cannot remain permanently active without interrupting the ma-
terial flow. The material can be classified, e.g., using a bar-code reader that generates the
signal C1 necessary for the changeover.

muting functions using a barcode reader

(by additional signal C1, generated by a bar-code reader)
material
In the example, the changeover between the partial blanking and muting functions is per-
formed using a bar-code reader. The different material heights are classified and saved
using bar-codes. The bar-code reader classifies the material and generates the change-
over signal C1 over a separate output as required.
If the bar-code reader detects low material , the partial blanking configured remains
active.
If the bar-code reader detects high material , it generates the additional signal C1 and
the configured changeover between partial blanking and muting is performed.
To activate muting, a LOW/HIGH signal change must occur on input C1, before both mu-
ting sensors in the first sensor pair (e.g. A1 and A2) are active. If this is not the case, the
partial blanking function is initiated on the activation of the sensors in the first sensor
pair.
If muting has been initiated, then a HIGH/LOW signal change must then occur on input
C1. If this is not the case, muting cannot be initiated again.
You will find information on the connection and on the possible combinations for the
additional signal C1 in section 6.10 “Combinable muting functions and facilities for
connecting” from page 63.

Always fit the key-operated switch so that the entire hazardous area can be seen.
The key-operated switch and its integration must comply with EN ISO 12100 and
6.8.2 Override realised with the integrated override function
The override function is activated with the aid of the CDS and differentiates between two
states Override required and Override.
Override required
The Override required state means that the output signal switching devices (OSSD) are in
the OFF state and the system is waiting for the activation of the override control switch.
The system signals this state with a flashing muting lamp (2 Hz) and at the same time
ndicates the cause of the error message on the 7Esegment display.
i
The Override required state is only triggered by the system if, during the presence of a
valid muting condition …
an error occurs, i.e. if at least one muting sensor is active and at least one is inactive
and
muting is brought to an end
and
the ESPE is interrupted by an object.
Errors can be triggered by the triggering of the concurrence monitoring, the monitoring of
the total muting time, the direction detection, the sequence monitoring or the sensor gap
monitoring, by the muting sensors or the muting lamp or by a re-start after an emergency
stop/mains voltage failure.
WARNING
Override
Please pay attention to the following safety notes for the Override state!
Install the control switch for override so that the entire hazardous area can be seen
when the switch is operated.
After clearing the system and before actuating the override make sure the plant is in
the correct state. Check in particular whether the following muting indicators are off:
If it is necessary to press the override button twice in two muting cycles one after the
other, the muting arrangement and the sensors must be checked.
Override (indication ) can only started in the override required state ( Yellow/red
2 Hz) by actuating the control switch for the override. The system continues the muting at
the point at which it was interrupted. The output signal switching devices (OSSD) switch to
the ON state and the system only monitors the override status.
Override can be triggered in two different ways:
with a separate control switch
with a common control switch for reset and override
Electrical connection of the control switch is described in the chapter “Electrical Installa-
tion” of the operating instructions of the corresponding UE403 or sens:Control device.
Configure override by allocating a control switch for reset/override to the related
connection using drag and drop. Device symbol M4000 Advanced (receiver) or M4000

For safety reasons the override duration is limited and is monitored using 2 time monitors.
he first time monitor lasts 30 minutes, the second time monitor lasts 60 minutes.
T
Both time monitors are started the first time the override control switch is actuated. The
following two conditions must be met:
1. The muting cycle initiated must have been brought to an end within 30 minutes, i.e. all
muting sensors and the ESPE must be clear again (objects/material has been moved
out of or removed from the area of the muting sensors/the ESPE).
2. A completely error-free muting cycle must have been completed within 60 minutes
without triggering of the override.
Effects of the conditions:
If both conditions are met, the system continues to operate normally (muting is trig-
gered on the presence of valid muting condition) and both time monitors are reset.
If the first condition is not met (30 minutes have elapsed), the system goes back into
the Override required state. The first time monitor re-starts and a further 30 minutes are
available to meet both conditions.
If the second condition is not met completely (a completely error-free muting cycle has
not been completed within 60 minutes), the system changes to the lockEout status.

7.1 Determining the minimum distance
The M4000 multiple light beam safety device must be mounted with an adequate mini-
mum distance:
to the hazardous area
from reflective surfaces
WARNING
Note
No protective function without sufficient minimum distance!
You must mount the multiple light beam safety device/s with the correct minimum
distance to the hazardous area. Otherwise the safe protection of the M4000 system is
not provided.
Risk of failure to detect!
Persons who are in the hazardous area but not in the light path between sender and
receiver are not detected by the M4000 system. It is therefore to be ensured that the
hazardous area is fully visible and any dangerous state can only be initiated if there are
no personnel in the hazardous area.
The M4000 system is not allowed to be used for hand and finger protection.
Read and follow the relevant safety standards!
The procedure described in the following sections for the calculation of the minimum
distance is no substitute for knowledge of the related safety standards.
Therefore read and follow in particular the standards stated in the following sections.
You will find further information on the application of the standards during the calculation
of the minimum distance in the SICK reference brochure “Guidelines Safe Machinery”
(part no. 8007988).
The applicable legal and official regulations apply to the use and mounting of the protec-
tive device. These regulations vary depending on the application.
A minimum distance must be maintained between the multiple light beam safety device
and the hazardous area. This ensures that the hazardous area can only be reached when
he dangerous state of the machine is completely at an end.
t
The minimum 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
etermined by taking a measurement.)

ANSI B11.19:2003G04, Annex D and Code of Federal Regulations, Volume 29,
Part 1910.217 … (h) (9) (v) depends on:

EN ISO 13857:
he following calculation shows an example calculation of the minimum distance.
Note
T
Depending on the application and the ambient conditions, a different calculation may be
necessary.
First, calculate S using the following formula:
S= 1600 × T + C [mm]
Where …
T= Stopping/run-down time of the machine
+ Response time of the M4000 system after light path interruption [s]
S= Minimum distance [mm]
C= Supplement [mm], depending on the number of beams (1, 2, 3 or 4)
If it is possible to reach over the vertical protective field of an ESPE, the
supplement C must be determined as per the tables in EN ISO 13855. Here the
following always applies: C
(reaching over) C
O
R
(reaching through)
T
R
Example 1: Access protection with two beams for a hazardous point, where there is no
risk of reaching over:
C = 850 mm
Stopping/run-down time of the machine = 290 ms
Response time of the light path interruption = 30 ms
T = 290 ms + 30 ms = 320 ms = 0.32 s
S = 1600 × 0.32 + 850 = 1362 mm
Example 2: Access protection with three beams for a hazardous point, where there is a
risk of reaching over:
Three-beam standard ESPE (300/400/1100 mm)
Height of the top edge of the protective field: 1100 mm
Height of the hazardous area: 1400 mm
As per EN ISO 13855 a resolution-dependent supplement C of 1100 mm applies (instead
of the previously usual 850 mm).
C = 1100 mm
Stopping/run-down time of the machine = 290 ms
Response time of the light path interruption = 30 ms

Once the system is mounted, one or several of the enclosed self-adhesive information
labels must be affixed:
– Use only information labels in the language which the users and operators of the
machine understand.
– Affix the information labels such that they are easily visible by the users and opera-
tors during operation. After attaching additional objects and equipment, the informa-
tion labels must not be concealed from view.
– Affix the information label “Important Notices” to the system in close proximity to
sender and receiver.
When mounting a M4000 with integrated laser alignment aid, ensure that the laser
warning labels on the device remain visible. If the laser warning labels are covered, e.g.
on installation of the M4000 in a device column (accessory), you must apply the laser
warning labels supplied with the receiver in the appropriate place on the cover.
Sender and receiver can be mounted in five different ways:
The Omega bracket is made of aluminium. The bracket is designed such that sender and
receiver can also be exactly aligned after the installation and mounting of the bracket.
Attach the screws of the Omega bracket with a torque of between 2 and 2.5 Nm. Higher
torques can damage the bracket; lower torques provide inadequate protection against
Engage the Omega fixing bracket in its profile rails. Additional spacers are used to

The machine/system could inadvertently start up while you are connecting the devices.
WARNING
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.
Connect OSSD1 and OSSD2 separately to the machine controller.
Ensure that the machine controller processes the two signals separately.
Prevent the formation 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 pro-
The two outputs are protected against short-circuits to 24 V DC and 0 V. When the light
path is clear, the signal level on the outputs is HIGH DC (at potential), when the light
beams are interrupted or there is a device fault the outputs are LOW DC.
The M4000 multiple light beam safety device meets the interference suppression
requirements (EMC) for industrial use (interference suppression class A). When used in
residential areas it can cause interference.
To ensure full electromagnetic compatibility (EMC), functional earth (FE) must be connected.
The external voltage supply of the devices must be capable of buffering brief mains
voltage failures of 20 ms as specified in EN 60204E1. Suitable power supplies are
available as accessories from SICK (Siemens type series 6 EP 1).
The plug alignment (direction of turn) in the housing may vary from device to device. You
can identify the correct pin assignment by the position of the pins in relation to each
other as shown in the drawings.

their de-energized position after the protective device has responded. 24 V is then applied
at the input of the EDM. If 24 V is not present after the response of the protective device,
then one of the contact elements is faulty and the external device monitoring prevents the
machine starting up again.

the application diagnostic output is to signal the alarm.
– HIGH active: If there is contamination or if the OSSDs are switched on, 24 V are
present. Otherwise the output is high resistance.
– LOW active: If there is contamination or if the OSSDs are switched on, the output is
high resistance. Otherwise 24 V are present.

If you connect the application diagnostic output as an alarm signal for muting or over-
ride status, then the application diagnostic output will always signal the alarm with an
active HIGH. With muting or override 24 V are present. Otherwise the output is high
resistance.
If you connect the signal output, then you must configure it with the aid of the CDS prior to
commissioning. Details can be found in chapter 5.3 “Application diagnostic output (ADO)”
on page 41.
Device configuration after replacement!
If you replace a multiple light beam safety device on which the application diagnostic out-
put (ADO) is connected and configured, then you must activate the application diagnostic
output (ADO) again via the CDS. It is not enough to only make the electrical connections.

Note
8.8 sens:Control applications
Using sens:Control, the intelligent interface technology for safety systems, SICK provides
you with an entire range of interface products that were specially developed for interfacing
safety products and machines.
For complex applications the M4000 can be integrated into UE100 sens:Control family
safety systems. In this way the functions of the multiple light beam safety device can be
enhanced and corresponding applications realised.
All variants of the M4000 Advanced, M4000 Advanced A/P and M4000 Area 60/80 are
equipped with EFI (safe SICK device communication). All safety-relevant signals are trans-
mitted using this interface. A bus interface to a safe fieldbus is possible using the series
UE1000 sens:Control device family.
You will find connection diagrams in the operating instructions for the series UE100 and
UE1000.
Commissioning requires a thorough check by qualified safety personnel!

on page 90ff).
9.2 Alignment of the M4000
After the multiple light beam safety device has been mounted and connected, you must
align the sender and receiver precisely in relation to each other.
Alignment is performed by mechanically adjusting the M4000 components. During this
process the M4000 is in the alignment mode. You can then see when the optimal align-
ment is achieved on the 7Esegment display on the receiver.
The alignment mode is automatically activated when the multiple light beam safety device
is switched on if the light beams are not yet aligned or the light path is interrupted.
You can conveniently and accurately align the devices using a laser alignment aid. An
alignment aid is recommended particularly when a M4000 system is used with deflector
mirrors (each mirror on the mirror columns must be adjusted).
The following alignment aids are available:
integrated laser alignment aid per beam (optional, only for M4000 Advanced)
On this subject read the description in chapter 9.2.4 “Alignment of the M4000 Ad-
vanced with integrated laser alignment aid (optional)” on page 95.

Notes
The beam that is closest to the 7Esegment display is termed the first light beam
(see Fig. 59 and Fig. 60).
Only the first and last light beam are evaluated during alignment.

9.2.3 Special aspects of alignment with deflector mirrors
If you use the M4000 multiple light beam safety device with deflector mirrors (mirror
columns), then you must note the following points when aligning the mirrors:
1. On the deflection of several beams using a mirror column, each individual mirror must
be adjusted separately.
2. For deflection using mirrors, the angle of incidence equals the angle of reflection. This
means: A slight rotation of the mirror results in a change that is twice as large
(see Fig. 61).
If the light beam is guided to the receiver using a deflector mirror, only part of the origi-
nal diverging beam is passed on.
The alignment tolerance will become smaller with each further deflection (see Fig. 62).
Recommendation

LASER CLASS 2
P 1 mW CW, = 630–680 nm
Complies with IEC 60825E1:2007

Laser Notice No. 50, June 24, 2007
Notes
The M4000 Advanced multiple light beam safety device is available with an integrated
laser alignment aid as an extra.
The laser alignment aid in conjunction with the indications on the 7Esegment display
enables you to precisely adjust and align the multiple light beam safety device. The aid
comprises a laser per light beam (in the receiver) as well as a laser deflector mirror and a
transparent display screen (in the sender).
The laser alignment aid is activated automatically when the M4000 Advanced is switched
on if the light beams are not yet aligned or if the light path is interrupted.
Always align the beams individually and in the following order: first beam, second
beam …, last beam (starting at the 7 segment display). When aligning the second and
all further beams, it may occur that the laser beams for beams already aligned (e.g. the
first beam) are no longer incident to the target on the alignment template (when this is
fitted again). This situation has no effect on the accuracy of the overall alignment. I.e.
beams already correctly aligned (e.g. first beam) do not need to be re-aligned after the
alignment of the next beam (e.g. second beam), even if the laser beam for the beam
previously aligned deviates from the target on the alignment template.
If the multiple light beam safety device is in the lockEout status when switched on (see
section “The lockE out status” on page 105), the laser alignment aid is not activated.
The laser alignment aid switches off automatically, …

In the delivery with the receiver for the M4000 Advanced with integrated laser align-
ment aid you will find two self-adhesive alignment templates (one template for the
deflector mirror and one for the sender). Keep both alignment templates at hand. You
will find further information on the alignment templates as well as a master for copying
in the annex 15.3.
Secure the plant/system. No dangerous state possible!
Ensure that the dangerous state of the machine is (and remains) switched off! During the
WARNING
alignment process, the outputs of the multiple light beam safety device are not allowed to
have any effect on the machine.
How to align the M4000 Advanced with the aid of the integrated alignment aid:
Check with a spirit level whether the devices and the deflector mirrors, if used, are
mounted vertically.
Check whether the following points are the same distance from the floor:
– first beam of the sender
– first beam of the receiver
– when using deflector mirrors: centre of the first mirror surface
Loosen the clamping bolts which hold the multiple light beam safety device in place.
Adhere the alignment template for mirrors to the individual mirror on the mirror pillar
that is used to deflect the beam to be aligned. If you start the alignment with the first
beam as per these instructions, this is the bottom mirror on the mirror pillar
(see Fig. 64).

Activate the laser alignment aid by switching on the power supply to the multiple light
beam safety device.
Note
You can also activate and deactivate the laser alignment aid via the CDS.
Rotate the receiver until the alignment beam is incident in the centre of the hole in the
alignment template (see Fig. 64). If further mirror columns are used, use the alignment
template for all further mirrors on the mirror columns.
Note
If you do not use an alignment template, the alignment beam must be incident approx.
Remove the alignment template from the individual mirror.

template.
Adhere the alignment template for the sender to the beam on the sender that is closest
to the 7Esegment display.
Note
The alignment template for the sender is correctly positioned on the sender
(see Fig. 65), when …
– the circular opening is exactly over the beam optics
and
– the tabs on the template are exactly positioned on the edges of the sender housing
and point upward from the 7Esegment/LED display.

Align the deflector mirror (depending on the mirror columns, you may need to remove
the cover plate first). With the aid of three adjusting screws, you can finely adjust the
individual mirror (see Fig. 66). The optimal alignment is achieved when the alignment
beam is incident in the middle of the rectangular hole in the alignment template.

For the alignment of the sender, the laser beam is deflected within the sender onto a
transparent display screen with the aid of the laser deflector mirror. As soon as correct
alignment is achieved, the display screen, which can be seen from the exterior, illumi-

Remove the alignment template. Watch the alignment information on the 7Esegment
display of the receiver (see Tab. 37). The optimal alignment of the beam near the 7Esegment display is achieved when a appears on the 7Esegment display.
Notes
When the alignment information on the 7Esegment display goes out (no indication), then
all other beams are already aligned.
The sender is only aligned once. This step is not necessary when aligning other beams.
Fix the sender in place.
Align the other beams using the steps described.
Note
When aligning the second and all further beams, it may occur that the laser beams for
beams already aligned (e.g. the first beam) are no longer incident to the target on the
alignment template (when this is fitted again). This situation has no effect on the accuracy of the overall alignment.
Using the clamping bolts, fix the receiver in place.
Switch the power supply off and then back on again and check via the 7Esegment dis-
play whether the alignment is correct after tightening the clamping bolts (see Tab. 37).
Note
All alignment templates used must be removed after the alignment procedure!
