Factory setting
The system features many functions without needing any additional
devices. The following table gives an overview of the possible functions
and the factory settings configuration.
Function Factory setting Configuration
Protective mode, automatic not active External wiring
Restart interlock
(manual reset)
not active External wiring
Double acknowledgement/
reset
not active with command device
Blanking fixed/floating not active with command device
Contactor control (EDM) not active with command device
Beam coding A not active with command device
By default neither the restart interlock (manual reset) nor the
protective mode is active. One of both operating modes must
be wired in order to enable the OSSD outputs. If no opera-
ting mode is selected, the following message is shown:
Status indication E1 + LED OSSD OFF (red)
2.8.1 Protective mode / Automatic
The protective mode switches the OSSD outputs to the ON state
(protection field not interrupted), without external release of a switching
device.
Wiring of the receiver
Jumper connection
pin 1 with pin 6
Pin 1 Pin 6
This operating mode generates an automatic restart of the machine if
the protection field is not interrupted.
A 24 VDC H-signal at the input of pin 1 leads to a restart of
the system. If the 24 VDC H-signal is still present at pin 1
after the self-test, the system switches to setting mode,
see chapter "Setting mode".
This operating mode may only be chosen in conjunction
with the restart interlock (manual reset) of the machine.
This operating mode must not be chosen, when persons
can step behind the protection field.
2.8.2 Restart Interlock (operation)
The restart interlock (manual reset) prevents an automatic enabling of
the outputs (OSSD's ON state) after switch-on of the operating voltage
or an interruption of the protection field. The system switches the
outputs only to ON state, when an external command device (restart
button) generates an enabling signal at the restart input (receiver).
Wiring of the receiver
- Jumper connection pin 5 with pin 6
- Command device (enabling button)

The command devices (enabling button) must be installed
outside of the hazardous area. The operator must have a
clear view on the hazardous area when actuating the

2.8.3 Restart interlock with double acknowledgement/reset
In applications with access monitoring, a complete overview of the haz-
ardous areas is often not possible; despite that, a reset of the command
device for the restart interlock outside of the hazardous area by third
parties is at all times enabled, although possible persons/operators
are in the invisible area. This hazardous situation can be avoided by
means of a double reset, i.e. integration of two command devices inside
and outside the hazardous area.

Specification
The operating mode is available, when the parameter setting -
double reset is activated (P 5). See chapter Parameter setting.
Sequence for enabling:
1) Actuate command device inside of the hazardous area (S2) and
leave the hazardous area
2) Go through protected field or interrupt at least one beam, then
release protected field
3) Actuate the command device outside of the hazardous area (S1)
Command device S1 can be reset (acknowledged) within a timeframe
of 2 to 60 seconds after the actuation of S2. If the order or the time
requirement is not respected, the process must be repeated.
Signaliling: LED restart (yellow)

2.8.4 Fixed blanking
The SLC440 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 addition-
ally blanked to increase the tolerance. See chapter Parameter setting
- Fixed blanking with movable edge regions (P 2).
Fixed blanking area
E1 R1
Key
Object in protection field
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.
2.8.5 Fixed blanking with movable edge region
This function can compensate slight position changes of one fixed
blanked object with a change of ± 1 beam. This position change cor-
responds 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 effective resolution
of the SLC440 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!
2.8.6 Floating blanking
The SLC440 safety light curtain can blank movable objects in the
protection field.
The SLC440 can be used for the floating blanking of 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 2) and
floating blanking (P 3) is not possible.

Key
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. material ejection or process-controlled material movement
without the outputs being disabled in case of material movement in the
protection field g. material ejection or process-controlled material move-
ment. 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. The
effective resolution must be registered permanently and clearly visible
onto the label affixed to the receiver.
Effective resolution
The effective resolution in case of activated blanking can be found in
the following table.

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.

2.8.7 Contactor control (EDM)
The contactor control monitors the controlled switching elements
(auxiliary contacts of the contactors) of both outputs. This monitoring
is realised after each interruption of the protection field and prior to the
restart (enabling) of the outputs. In this way, malfunctions of the con-
tactors are detected, e.g. contact welding or contact spring breakage.
If the light curtain detects a malfunction of the switching elements, the
outputs are locked.
After elimination of the error, a power reset is required.
The contactor control is not activated upon delivery. The
function is activated in parameter setting mode (P 4).

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 pro-
tection field is free, 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-rele-
vant 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
The preset beam coding of the safety light curtain must be adjusted,
when systems operating in each other's vicinity and a set-up as shown
in the image below (no interference) is impossible. When supplied, the
beam coding A is not active. A receiver with activated beam coding A
can distinguish the beams of the transmitter with the same beam cod-
ing, which are destined to this particular receiver, from foreign beams.
If adjacent systems are operated without beam coding A,
the user is at risk.

3. Mounting
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 must not be used on machines, which can be stopped
electrically in case of emergency.
The safety distance between the SLC 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 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.
Never connect the outputs to +24VDC. If the outputs are wired to
+24VDC, they are in ON state, as a result of which they are unable to
stop a hazardous situation occurring on the application/machine.
The safety inspections must be conducted regularly.
The SLC must not be exposed to inflammable or explosive gasses.
The connecting cables must be connected in accordance with the
installation instructions.
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 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 must be installed so that personnel are always located within
the detection zone of the safety device when operating the hazardous
machine parts to be secure.
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. Transmitter and receiver must be fitted parallel to each other and at
the same height.
2. Choose the operating mode "Automatic" (see chapter Protective
mode/automatic) and switch the operating voltage on.
3. The 7-segment display in the receiver shows the current signal quali-
ty/fine setting (signalling, see chapter "set-up mode") for 30 seconds.
Rotate the transmitter and then the receiver towards each other until
you have the best possible signal strength of 3 horizontal bars (7
segment display) (note that 2 horizontal bars is sufficient). Fix this
position using the screws to the mounting angle.If the set-up is not
possible within 30 seconds, change to set-up mode (see chapter
"set-up mode").
The set-up mode leads to the best possible positioning of the sen-
sors through the basic setting (position of the second and last beam)
and the optimisation with the fine adjustment (total signal).
Status indication of the LED
OSSD ON (green) is active, signal strength (orange) is not active.
3.4 Setting mode
Setting tool with 7-segment display
The function supports the best possible alignment between transmitter
and receiver. The indication shows the signal strength of the different
receivers while the safety outputs are switched off. For the optical
indication of the signal strength two areas area available, the signal
strength of the second (with SLG first) and the last beam in the protec-
tion zone (default setting) as well as the best possible orientation of all
beams (find adjustment).
Activating setting mode
After the system start, a signal impulse (H signal 24 VDC) must be
present at the input restart interlock (pin 1) of the receiver for at least
2.0 seconds (pushbutton/enabling).
The 7 segment display starts with the default setting (vertical bar). The
sensors are aligned in parallel and at the same height until both seg-
ments have reached a signal strength of 50% to 100%.
With a signal impulse on the input release (pin 1) you can change be-
tween default setting and fine adjustment as long as the signal strength
is at 50% of the default setting (vertical bar).
After the setting of the sensors, the setting mode can be terminated
by the presence of a HI-signal at pin 1 for at least 2.5 seconds (max. 6
seconds) and the actuation of the enabling button or by a voltage reset
at the receiver (+UB).
Status display
The signal strength is also shown on the display in the diagnostic win-
dow by yellow light pulses to the status light. The better the alignment,
the higher the frequency of the light pulses. The alignment is correct
when the light pulses switch over to continuous light.
If there is no optical synchronisation between the transmitter and the
receiver, a light pulse is emitted every three seconds. The setting mode
is ended by a system start ( +UB OFF/ON).

or operation at nominal range the best possible signal
strength (3 segments)is not reached.
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 dis-
tance 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:

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

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 = 10 ms
Resolution of the safety light curtain = 14 mm
Stopping time of the machine = 330 ms
S = 2000 mm/s * (330 ms + 10 ms) + 8(14 mm - 14 mm)
S = 680 mm
S = > 500 mm, therefore new calculation with V = 1600 mm/s
S = 544 mm

The safety distance for resolution > 40 mm is calculated by means
of the following formula:

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.

5. Set-up and maintenance
5.1 Check before start-up
Prior to start-up, the following items must be checked by the responsi-
ble person.
Wiring check prior to start-up
1. The voltage supply is a 24V direct current power supply (see tech-
nical specifications), which meets the CE Directives, Low Voltage
Directives. A power downtime of 20 ms must be bridged.
2. Presence of a voltage supply with correct polarity at the SLC.
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. The double insulation between the light curtain output and an exter-
nal potential is guaranteed.
5. The outputs OSSD1 and OSSD2 are not connected to +24 VDC.
6. The connected switching elements (load) are not connected to +24
VDC.
7. If two or more SLC are used within close range compared to each
other, an alternating arrangement must be observed. Any mutual
interference of the systems must be prevented.
Switch the SLC 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-seg-
ment 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.
5.2 Maintenance
Do not use the SLC 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 oper-
ating principle of the SLC and the machine must be known in order to
be able to conduct 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 conduct the
maintenance.

3. Hazardous machinery parts can only be accessed by passing
through the protection field of the SLC.
4. The staff remains within the detection area, when works are conduct-
ed 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 is switched off.
5.4 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 are correctly connected to the machine.
4. The total response time of the machine does not exceed the re-
sponse time calculated during the first putting into operation.
5. The cables, the connectors, the caps and the mounting angles are in
perfect condition.
5.5 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.

6.2 Fault diagnostic
The light curtain performs an internal self-test after the operating voltage is switched on and the protection field is enabled. When a fault is detected,
an error number e.g. E1 is displayed at the receiver. Each fault display is followed by a one-second delay.
Status display Fault feature Action
Wiring error, operating mode not defined
(automatic or restart mode)
Check all connections at the receiver,
Jumper connection 1 or jumper connection 2 present?
Supply voltage UB = 24V/DC ± 10%, check voltage source and primary voltage, note: after
the fault message E2 has been displayed three times, a reset is executed.
Error output (e), OSSD1 or OSSD2 Check the connections of both outputs, short-circuit of both OSSD,
connection to level 0V or 24V, deactivate external (relay) cross-wire short
monitoring
Contactor control (EDM) EDM active: check connections of both NC contacts,
EDM not active: check level at Pin 8, open input
Beam blanking Check the blanking area(s) of fixed or floating objects with the selected
parameter setting, fault elimination - repeat configuration in the parameter
setting, possibly adjust P 1, P 2, P 3
Configuration error in parameter setting Check parameter setting and save/accept with "S." or delete/reset with
"C."
