2. Product description
2.1 Destination and use
The SLC/SLG440AS is a non-contact, self-testing safety guard which
is used for the protection of hazardous points, hazardous areas and
machine accesses. If one or more light beams are interrupted, the
hazardous movement must be stopped.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
The entire concept of the control system, in which the
safety component is integrated, must be validated to the
relevant standards.
An AS-Interface Safety at Work component functions on the basis of
an individual code generator (8 x 4 bit). This safety code is cyclically
transmitted over the AS-i network and monitored by a safety monitor.

2.8 Functions
The system consists of a receiver and a transmitter. For the described
functions, no further switching elements are required. The diagnostics
and the function selection are realised by means of the parameter
adapter (KA-0975), refer to chapter "Parameter setting".
The BWS is set to „Automatic protection mode“ .
A possible restart interlock must be congured in the
AS-i safety monitor.
The SLC has the following features:
• Blanking of fixed protection field areas
• Blanking of fixed protection field areas with movable edge region
• Blanking of movable protection field areas
The SLG has the following features:
• Blanking of movable protection field areas
Systems with alternative beam coding A can be ordered through
the type code (refer to type code).
2.8.1 Fixed blanking SLC440AS
The SLC440AS can blank stationary objects in the protection field.
Multiple protection field areas can be blanked. If small changes
are made within the fixed blanking area, each time 1 beam can be
additionally blanked to increase the tolerance. See chapter Parameter
setting - Fixed blanking with movable edge regions (P 2).

Mechanical cover
The range of the fixed blanking can be arbitrarily chosen in the
protection field.
The first beam line, which realises the optical synchronisation and is
located immediately behind the diagnostic window, cannot be blanked.
The area of the fixed blanking must not be modified after the teach-
in process. Any change of the area or removal of the object from the
protection field will be detected by the system. As a result, the outputs
are disabled (locked). This locking can be neutralised by executing a
new teach-in process in accordance with the actual beam interruptions.
The function is activated by means of the parameter setting
(P1). If the function is activated, the LED blanking in the
diagnostic window of the receiver starts flashing.
See chapter Parameter settings.
• The remaining lateral areas must be protected against
intrusion by means of mechanical covers.
• The lateral covers must be fixed with the object.
• Partial covers are not authorised.
• After the fixed blanking, the protection field must be tested
by means of the test rod.
• The restart interlock function of the safety light curtain or the
machine must be activated.
2.8.2 Fixed blanking with movable edge region SLC440AS
This function can compensate slight position changes of afixed blanked
object with a change of +/- 1 beam. This position change corresponds
to an amplitude of approx. +/- 10 mm resolution 14 mm and approx.
+/- 20 mm resolution 30 mm upwards and downwards in the protection
field.

The operating mode is only available, when the parameter setting -
fixed blanking with movable edge region is activated (P 2).
See chapter Parameter setting.
A combination with only fixed beam blanking (P 1) or additional floating
beam blanking (P 3) is not possible.
This blanking changes the physical resolution. The then effective
resolution of the SLC440AS can be found in the table in the chapter
"Floating blanking" (1 beam).
Perform a new calculation of the safety distance with the
effective resolution. Adjust the safety distance in accordance
with your calculation.
2.8.3 Variable blanking SLC440AS
The SLC440AS safety light curtain can blank movable objects in the
protection field.
The SLC440AS can be used for the floating blanking of to 2 beams in
the protection field, refer to parameter setting (P 3). A combiniation of
fixed and floating beam blanking (P 1 and P 3) is enabled.
A combination of fixed blanking with movable edge region (P 1) and
floating blanking (P 3) is not possible.
Example:

Legend:
1: Fixed blanking area
2: Floating blanking area
The function enables an arbitrary floating blanking of partial areas in the
protection field. The first beam, which is located immediately behind
the diagnostic window, cannot be blanked.
This function allows for an interruption of the protection height without the
outputs being disabled in case of material movement in the protection
field, e.g. material ejection or process-controlled material movement. g.
material ejection or process-controlled material movement. This extension
of the object detection increases the resolution. In this way, the physical
resolution changes into an effective resolution. This effective resolution
must be used to calculate the safety distance. Use formula (1) to calculate
the safety distance with the effective resolution if a maximum of 2 light
beams are blanked; use formula (3) indicated in the "Safety distance"
chapter if more than 2 light beams are blanked. The number of beams to
be blanked is limited, see Table Effective resolution.
In a system with a 14 mm physical resolution, the effective resolution is
increased to 34 mm in case of a floating blanking of 2 beams (68 mm for
a system with a resolution of 30 mm). The effective resolution must be
permanently known and well visible on the information label of the receiver.
Effective resolution
The effective resolution in case of activated blanking of floating beams
can be found in the following table:
Resolution 14 mm
Blanked beams Physical resolution Effective resolution
1 14 24
2 14 34
Resolution 30 mm
Blanked beams Physical resolution Effective resolution

2 30 68
The function is activated in parameter setting mode (P 3). If
the function is activated, the LED blanking in the diagnostic
window of the receiver starts flashing.
Perform a new calculation of the safety distance with the
effective resolution. Adjust the safety distance in accordance
with your calculation.
• The standard IEC/TS 62046 includes information, which
describes possibly required additional measures to prevent a
person from reaching a hazard through the blanking areas of a
protection field.

The moving blanking range is authorised for individual beams in case of
obstacles, taking the protective function into account.
The function enables an arbitrary floating blanking of partial areas in the
protection field. The first beam, which is located immediately behind
the diagnostic window, cannot be blanked.
This function allows for an interruption of maximum 1 light beam
without the outputs being disabled in case of material movement in the
protection field, e.g. ejection of material or process-controlled material
movement.
The operating mode is only available, when the parameter setting P 3 is
activated. See chapter Parameter setting.

• The variable blanking of one beam is not authorised with the
2-beam SLG440AS!
• The blanking of one beam at the most in the SLG440AS
3-beam version or the SLG440AS 4-beam version is au-
thorised, provided that the protective function is taken into
account.
• The restart interlock (manual reset) function of the safety
light grid or the machine must be activated.
• The protection field must be checked with a test rod by a
qualified person after the configuraiton.
• The standard IEC/TS 62046 includes information, which
describes possibly required additional measures to prevent
a person from reaching a hazard through the beam blanking
of a protection field.
2.9 Self-test
The system performs a complete self-test and safety test within 2
seconds after the operating voltage has been switched on. If the
protection field is not interrupted, the system switches to the ON
condition (automatic mode). In case of an error, the outputs at the
receiver do not switch to the ON state. An error message is emitted in
the form of an error code. For more information, refer to chapter Fault
diagnosis.
During operation, the system executes a cyclic self-test. Safety-
relevant faults are detected within the reaction time and cause the
outputs to be switched off and an error code to be emitted.
2.10 Beam coding A
For systems where mutual interferences can be expected,
transmitters and receivers with alternative beam coding must be
used.
This could be required, when systems are operating in each other's
vicinity and a set-up as shown in the image below (no interference)
is possible. A receiver with activated beam coding A can distinguish
the beams of the transmitter with the same beam coding, which are
destined to this particular receiver, from foreign beams.
If adjacent systems are operated without beam coding A,
the user is at risk.
EERR
ERRE
No interference Interference:
beam coding A required!
• The beam coding A avoids mutual interference of adjacent systems.
• The beam coding A is permanently shown by the transmitter and the
receiver by means of flashing LED's (refer to LED status information).
• The beam coding A must be ordered separately for each sensor
(transmitter and receiver).
2.11 Parameter setting

3.1 General conditions
The following guidelines are provided as preventive warning notices
to ensure a safe and appropriate handling. These guidelines are an
essential part of the safety instructions and therefore must always be
observed and respected.
• The SLC/SLG must not be used on machines, which can be
stopped electrically in case of emergency.
• The safety distance between the SLC/SLG and a hazardous
machine movement must always be observed and respected.
• Additional mechanical safety guards must be installed so that
the operator has to pass by the protection field to reach the
hazardous machine parts.
• The SLC/SLG must be installed so that the personnel always
must be within the detection zone when operating the
machine. An incorrect installation can lead to serious injuries.
• The safety inspections must be conducted regularly.
• The SLC/SLG must not be exposed to inflammable or
explosive gasses.
• Round M12 connecting cables with a minimum length of
0.2 m must be used.
• The SLC/SLG must be mounted by means of the mounting
angles included in delivery.
• Device housing installed with at least 7.7 mm distance to
metal surfaces.
• The fixing screws of the end caps and the mounting angle
must be firmly tightened.
3.2 Protection field and approach
The protection field of the SLC/SLG consists of the entire range located
between the protection field markings of transmitter and receiver.
Additional protective devices must ensure that the operator has to pass
by the protection field to reach the hazardous machine parts.
The SLC/SLG must be installed so that the personnel is always located
within the detection zone of the safety device when operating the
hazardous machine parts to be secured.
Correct installation
Hazardous machine parts can only be reached
after passing through the protection field.
The presence of staff members between the
protection field and hazardous machine parts
must be prevented/avoided (protection against
stepping over).
Unauthorised installation
Hazardous machine parts can be reached
without passing through the protection field.
The presence of staff members between the
protection field and hazardous machine parts
is enabled.

3.3 Alignment of the sensors
Procedure:
1. The transmitter and the receiver must be fitted parallel to each other
and at the same height.
2. Switch on the power supply for the SLC/SLG.
3. The 7-segment display in the receiver shows the current signal
quality/fine setting (signalling, see chapter "setting mode")
permanently in protective mode. First turn the transmitter, then the
receiver towards each other until the best possible signal quality of
3 crossbars is obtained (7-segment display) (note: 2 crossbars =
sufficient). Fix the position with the two screws for each mounting
bracket. If the set-up is not possible with fine setting, switch to set-up
mode (see chapter "set-up mode"). The set-up mode leads to the
best possible positioning of the sensors through the basic setting
(position of the second and last beam) and the optimisation of the
fine setting (total signal).
Status indication of the LED's:
OSSD ON (green) is active (ON), signal quality (orange) not active.
4. After positioning, the SLC/SLG is ready for operation.
3.4 Set-up tool and set-up mode
Set-up tool with 7-segment display
The function supports the best possible alignment between transmitter
and receiver.
In normal operation, the signal strength is permanently displayed on the
receiver, when the safety enabling is switched on.
For the optical representation of the signal quality, two ranges, the
signal strength at the 2nd and the last beam in the protection field
(basic setting) and the optimal alignment quality of all beams (fine
adjustment) are available.
Activating setting mode:
The set-up mode can be activated through the parameter setting menu
by means of the parameter adapter KA-0975 (also refer to "Parameter
setting").
If set-up mode is activated, you can switch between rough and fine
setting by briefly pressing the button (2).
If the button is pressed for a longer period of time, the set-up tool is
closed and the receiver switches to protective mode

Best possible signal strength
Signal strength for normal operation OK
- Signal strength OK, if one or more beams in the protection
field are covered (beam blanking)
- Signal strength insufficient, when no beams are covered
The safe operating status (high availability) is also ensured,
when the best possible signal strength (3 crossbars) is not
obtained due to soiling of the profiles or installation at nominal
range.
3.5 Safety distance
The safety distance is the minimum distance between the protection
field of the safety light curtain and the hazardous area. The safety
distance must be observed to ensure that the hazardous area cannot
be reached before the hazardous movement has come to standstill.
Calculation of the safety distance to EN ISO 13855 and EN ISO 13857
The safety distance depends on the following elements:
• Stopping time of the machine (calculation by run-on time
measurement)
• Response time of the machine and the safety light curtain and the
down-stream safety-monitoring module (entire safety system)
• Approach speed
• Resolution of the safety light curtain
Calculation of the safety distance for the safety light curtain
SLC 440AS
The safety distance for resolutions 14 mm up to 40 mm is calculated by
means of the following formula:
(1) S = 2000 mm/s * T + 8 (d - 14) [mm]
S = Safety distance [mm]
T = Total reaction time (machine run-on time, reaction time of the safety
guard, relays, etc.)
d = Resolution of the safety light curtain
The approach speed is covered with a value of 2000 mm/s
If value S <= 500 mm after the calculation of the safety distance, then
use this value.
If value S >= 500 mm, recalculate the distance:
(2) S = 1600 mm/s * T + 8 (d - 14) [mm]
If the new value S ≥500 mm, use this value as safety distance.
If the new value S <500 mm, use a minimum distance of 500 mm.
Example:
• Reaction time of the safety light curtain = 13 ms
• Resolution of the safety light curtain = 14 mm
• Stopping time of the machine = 330 ms
S = 2000 mm/s * (330 ms + 13 ms) + 8(14 mm - 14 mm)
S = 686 mm
S ≥ 500 mm, therefore new calculation with V = 1600 mm/s
S = 549 mm

Calculation of the safety distance for the multi-beam light grid
SLG440AS
S = (1600 mm/s * T) + 850mm
S = Safety distance [mm]
T = Total reaction time (machine stopping time, reaction time of the
safety guard, relays, etc.)
K = Approach speed 1600 mm/s
C = Safety supplement 850 mm
Example
• Reaction time of the safety light grid = 13 ms
• Stopping time of the machine T = 170 ms
S = 1600 mm/s * (170 ms + 13 ms) + 850 mm
S = 1143 mm

The formulae and calculation examples are related to the vertical
set-up (refer to drawing) of the light curtain or light grid with regard to
the hazardous point. Please observe the applicable harmonised EN
standards and possible applicable national regulations.
The safety distance between the safety light grid and the
hazardous point must always be respected and observed. If
a person reaches the hazardous point before the hazardous
movement has come to a standstill, he/she is exposed to
serious injuries.
To calculate the minimum distances of the safety guards
with regards to the hazardous point, the EN ISO 13855 and
EN ISO 13857 must be observed.
If an overlap of the protection field is possible, take care with
the calculation of the safety distance referring to additional
CRO according to the table A1 as per norm EN ISO 13855.
3.5.1 Minimum distance to reflecting surfaces
During the installation, the effects of reflecting surfaces must be taken
into account. In case of an incorrect installation, interruptions of the
protection field could possibly not be detected, which could lead to
serious injuries. The hereafter-specified minimum distances with regard
to reflecting surfaces (metal walls, floors, ceilings or parts) must be
imperatively observed.

the control interface of the AS-i master (see component description) by
using the "Write parameter" instruction (with hexadecimal value F). This
(non-safe) diagnostic information from the reflected parameters or the
answer to a "Write parameter instruction" can be used by the user for
diagnostic purposes or for the control programme.
Diagnostic information P0 … P3
Parameter bit Condition = 1
P0 -
P1 Poor beam quality
P2 -
P3 Internal device error detected (FID)
The warning message indicates a soiled or incorrectly adjusted BWS.
The warning message indicates a soiled or incorrectly adjusted AOPD.
6.5 Diagnostic signal periphery error (FID)
An internal device error is transmitted as "periphery error" to the control
system through the AS-i Master.
A "periphery error" (FID input of the AS-i chip) is signaled by the
alternating red and green flashing of the AS-i duo LED on the AS-i
device.
7. Set-up and maintenance
7.1 Check before start-up
Prior to start-up, the following items must be checked by the
responsible person.
Wiring check prior to start-up:
1. For the auxiliary voltage supply, a 24 VDC PELV unit must be used
(refer to technical data).
A power downtime of 20 ms must be bridged.
2. Presence of a voltage supply with correct polarity at the SLC/SLG.
3. The connecting cable of the transmitter is correctly connected to the
transmitter and the connecting cable of the receiver correctly to the
receiver.
4. If two or more SLC/SLG units are used within close range to each
other, an alternating arrangement must be observed.Any mutual
interference of the systems must be prevented.
Switch the SLC/SLG on and check the operation in the following
way:
The component performs a system test during approx. 2 seconds
after the operating voltage has been switched on (indication through
7-segment display). After that, the outputs are enabled, if the protection
field is not interrupted. The LED "OSSD ON" at the receiver is on.
In case of incorrect functionality, please follow the instructions
listed in the chapter Fault diagnostic.

7.2 Maintenance
Do not use the SLG before the next inspection is
terminated. An incorrect inspection can lead to serious
and mortal injuries.
Conditions
For safety reasons, all inspection results must be archived. The
operating principle of the SLC/SLG and the machine must be known
in order to be able conducting an inspection. If the fitter, the planning
technician and the operator are different persons, please make sure
that the user has the necessary information at his disposal to be able
conducting the maintenance.
7.3 Regular check
A regular visual inspection and functional test, including the following
steps, is recommended:
1. The component does not have any visible damages.
2. The optics cover is not scratched or soiled.
3. Hazardous machinery parts can only be accessed by passing
through the protection field of the SLC/SLG.
4. The staff remains within the detection area, when works are
conducted on hazardous machinery parts.
5. The safety distance of the application exceeds the mathematically
calculated one.
Operate the machine and check whether the hazardous movement
stops under the hereafter-mentioned circumstances.
1. Hazardous machine parts do not move when the protection field is
interrupted.
2. The hazardous machine movement is immediately stopped, when
the protection field is interrupted with the test rod immediately before
the transmitter, immediately before the receiver and in the middle
between the transmitter and the receiver.
3. No hazardous machine movement when the test rod is within the
protection field.
4. The hazardous machine movement comes to standstill, when the
voltage supply of the SLC/SLG is switched off.
7.4 Half-yearly inspection
The following items must be checked every six months or when a
machine setting is changed.
1. Machine stops or does not inhibit any safety function.
2. No machine modification or connection change, which affects the
safety system, has taken place.
3. The outputs of the SLC/SLG are correctly connected to the machine.
4. The total response time of the machine does not exceed the
response time calculated during the first putting into operation.
5. The cables, the connectors, the caps and the mounting angles are in
perfect condition.
7.5 Cleaning
If the optics cover of the sensors is extremely soiled, the OSSD outputs
can be disabled. Clean with a clean, soft cloth with low pressure.
The use of agressive, abrasive or scratching cleaning agents, which
could attack the surface, is prohibited.
8. Disassembly and disposal
8.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
8.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
