Table 2.1-1: Safety-related characteristic parameters of the SOLID-2 Safety Light

• The safety sensor protects persons at access points or at points of operation of
machines and plants.

• The safety sensor with vertical mounting detects the penetration by fingers and hands
at points of operation or by the body at access points.

• The safety sensor only detects persons upon entry to the danger zone; it does not
detect persons who are located within the danger zone. For this reason, a start/restart
interlock is mandatory.

• The safety sensor with horizontal mounting detects persons who are located within the
danger zone (presence detection).

• 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 tested regularly by competent personnel.

• The safety sensor must be exchanged after a maximum of 20 years. Repairs or the
exchange of parts subject to wear and tear do not extend the service life.

3.1 The opto-electronic protective device

Working principle

SOLID-2 consists of a transmitter and a receiver. Beginning with the first beam (the
synchronizing beam) directly after the display panel, the transmitter pulses beam for
beam in rapid sequence. The synchronization between transmitter and receiver is
performed optically.

Fig. 3.1-1: Working principle of the opto-electronic protective device

The receiver recognizes the specially coded pulse packages of the transmitter beams
and opens the corresponding receiver elements in sequence in the same rhythm. A
protective field is consequently formed in the area between transmitter and receiver.

Its height depends on the geometrical dimensions of the protective device and its width is
determined by the distance selected between the transmitter and receiver within the
permissible detection range.

Functions such as start/restart interlock or contactor monitoring can optionally be
performed by the Receiver Extended version.

3.2 Functions of the Transmitter

3.2.1 Transmission channel

The infrared beams are modulated with specially coded pulse packages so that the are
distinct from ambient light, thus ensuring undisturbed operation.

Welding sparks or warning flash lights from passing forklifts do not having any effect on
the protective field.

If two protective fields are located directly next to each other for two adjacent machines,
however, measures must be taken to ensure the optical protective devices do not affect
each other.

Both transmitters should first be assembled “back to back“ so that the beams radiate in
opposite directions. This prevents one system from affecting the other.

Fig. 3.2-1: Transmission channel selection

Both the transmitter and the receiver of the optical protective system in question must be
switched from transmission channel 1 to 2. For additional information, see Chapter 6.

If external testing is desired, the test input of the transmitter must be wired in accordance
with the connection and operating instructions of the selected testing safety interface. The
testing safety interface will turn the transmitter off and back on, verifying that the selected
single OSSD of the receiver is turned off and on in accordance. For more details, see
Chapter

In most cases, however, internal cyclical testing is sufficient. For this purpose, the
transmitter‘s test input must be connected with +24V DC. Both OSSDs must be integrated
into the safety circuit as a two-channel system.

or is restored after a power outage. The receiver only switches to the ON state by pressing
and releasing the start/resart button within a time window.

5 Installation

This section contains important information on installing the SOLID-2. The effects of its
effective protection are only guaranteed if the following installation requirements are
observed. These installation specifications are based on the respective applicable
versions of European standards such as EN 999 and EN
countries outside of the EU, the valid requirements in those countries must also be
observed. The installation depends greatly on the type of protection being provided.

Because of this, the situations of:

• Safeguarding danger points

• Safeguarding danger areas

• Access guarding

are considered separately below. The applicable distance from the protective device to
reflective surfaces in the surrounding area are presented for all types of protection based
on these situations.

5.1 Calculating minimum distances

Light curtains can only perform their protective function if they are mounted with a
sufficient safety distance. The calculation formulas for the safety distance depend on the
type of protection. In the harmonized European standard EN 999, “Positioning of
protective devices with regard to approach speed of parts of the human body“, the
installation situations and calculation formulas for safety distance are described for the
types of protection named above.

The formulas for the required distances to reflective surfaces are based on the European
standard for “Active opto-electronic protective devices“ prEN IEC 61496-2.

In the close range of 500 mm, 2000 mm/s is used for the calculation. If the dis­tance greater than 500 mm is calculated, K = 1600 mm/s may be used.
However, in this case a minimum safety distance of 500 mm is applied.

Special notes on mounting a SOLID-2 Safety Light Curtain for safeguarding danger
points (

✟ Calculate the safety distance according to the formula in Chapter 5.1.1.
✟ Ensure that it is impossible to reach under, over, around or walk behind the protective

field.

✟ Observe the maximum distance between machine table and protective field of 75 mm,

with reference to a table height of 750 mm. If this is not possible because the safety
distance is too big, e.g. a mechanical barrier must be provided.

✟ Observe the minimum required distance to reflective surfaces.
Special notes on mounting a SOLID-2 Safety Light Curtain for safeguarding danger areas

(

see Fig. 5.1-2):

✟ Calculate the safety distance according to the formula in Chapter 5.1.2.
✟ The resolution determines the minimum height of the protective field above the floor.

The calculation formula can also be found in Chapter

✟ Ensure that the maximum height of the protective field above the reference plane of

1000 mm is not exceeded and only heights equal to or less than 300 mm are
considered impossible for an adult to crawl under (also see EN 999).

✟ It must not be possible to step into the danger area from the sides. Suitable hard guards

must be provided.

✟ Consider the position of the last light beam before the machine. It must not be possible

to stand undetected between this light beam and the machine.

5.3 Mechanical mounting

What should generally be taken into consideration during installation?

✟ Make certain that the transmitter and receiver are mounted on even surfaces.
✟ The transmitter and receiver must be positioned at the same height and their

connection plugs must be pointing in the same direction.

✟ Use screws for mounting that can only be loosened with a tool.
✟ Fasten and secure the transmitter and receiver so that they cannot be swiveled or

moved. Securing transmitter and receiver so they cannot be moved or swiveled is
especially important in the close area with a narrow protective field.

✟ The safety distance between the protective field and the danger zone must be

observed.

✟ Make certain that access to the danger point/danger area is only possible through the

protective field. Additional access routes must be secured separately (for example by
hard guards, additional safety light curtains or doors with locking devices).

Warning!

Before placing the SOLID-2 in operation for the first time on a power-driven production
machine, an experienced and commissioned person with suitable training must check the
entire setup and the integration of the opto-electronic protective device into the machine
control system.

Before connecting the supply voltage for the first time and while the transmitter and
receiver are being aligned, it must be ensured that the outputs of the protective device do
not have any effect on the machine. The switching elements that finally set the dangerous
machine in motion must be safely switched off and secured form restarting.

The same precautionary measures apply after every change in operating mode made to
the protective device, after repairs or during maintenace work.

Only after it has been determined that the optical protective device functions are correct it
can be integrated into the machine’s control circuit!

7.1 Startup

Warning!

Without internal start/restart interlock function and the protective field is free the OSSDs
immediately switch to the ON state!

Make certain that the transmitter and receiver are protected against overcurrent (for fuse
size see Chapter
power supply must have a load current reserve of at least 1 A and the ability to bridge a
power outage for at least 20 ms, and it must guarantee secure mains supply isolation.

7.1.2 Receiver display

After the receiver is turned on or restarted, the number of the selected transmission
channel appears.

Warning!

In the event of an error or fault, the receiver’s 7-segment display reports it with ”E xx“ or ”F
xx“. The error code in Chapter 9 provides information on whether it is an error (E xx) in
external wiring or an internal device fault (F xx). For internal faults, immediately interrupt
the installation and send in the malfunctioning receiver to be checked.

7.2 Aligning transmitter and receiver

Transmitter and receiver must be mounted in place at the same height or, if they are used
horizontally, at the same distance from the reference level.

7.2.1 Optimized aligning with the aid of the Receiver’s 7-segment display

The distinction between protecting field is free (channel number is shown continuously)
and the weak signal mode (channel number is flashing) can be used as a convenient
alignment tool.

When the components are already almost aligned it is recommended to improve the
alignment e.g. by turning the receiver. Turn the receiver with slightly loosened brackets
until the 7-segment display starts to blink. Memorize this position. Now turn the receiver in
the opposite direction until the display lights constantly and further, until it is blinking
again. Now turn the receiver back in between the two positions determined. Screw the
receiver firmly into place to prevent turning. Proceed with the transmitter in the same
manner.

Testing

8 Testing

DEUTSCH ENGLISH FRANÇAIS ITALIANO ESPAÑOL NEDERLANDS

8.1 Testing before setting the protective device in service the first time

Testing by an experienced technician before initial startup must ensure that the optical
protective device and any other safety components that might be present have been
selected in accordance with the required specifications, especially the European Machine
and Machine Utilization Directive, and that they provide the necessary protection when
properly operated.

✟ Use the regulations listed above, where required, with the help of the checklists

provided in the Appendix of these instructions, to check that the protective devices are
properly installed, that they are properly wired into the controls and that they work in all
machine operating modes. When selecting the checklist, note the type of protection
(danger point, danger area or access guarding).

✟ The same testing requirements apply if the machine in question has not been operated

for a longer period of time and after major modifications or repairs if this could affect the
safety of the machine.

✟ Observe the specifications regarding the instructing of operation personnel by experi-

enced technicians before work is started. Instruction of personnel is the responsibility of
the machine owner.

Leuze electronic offers a specialist service, which undertakes the required testing and
monitoring tasks in accordance with the European regulations (www.leuze.de). The results
of these tests are documented for the machine owner consistent with ISO

8.2 Regular tests

Regular tests must also be carried out in accordance with local regulations. They are
designed to discover changes (e.g. in machine stopping times) or manipulations to the
machine controls or protective device.

✟ You must have the effectiveness of the protective device checked by an experienced

technician at suitable intervals, but at least once per year.
✟ The applicable checklist in the Appendix may also be used during regular testing.
Leuze electronic also provides a specialist service for regular tests.

9000.

8.3 Daily testing with the test rod

SOLID-2 Safety Light Curtains are subject to a cyclical testing. Nevertheless it is very
important to check the protective field for its effectiveness daily to ensure that the
protection stays effective at every point after an operation mode or tool change.

Warning!

Use the appropriate test rod (Accessory) but never your fingers, hand or arm for checking
the system!

✟ When selecting the test rod’s diameter, use the nameplate of the receiver indicating the

resolution as a guideline.
✟ If for Receiver Extended the internal start/restart interlock function is selected and the

AOPD is released, LED1 lights up green. When the test rod is inserted, LED1 switches

to red and LED2 stays in the OFF state. During the test procedure, the yellow LED2
must not light up at any point. Only after the test rod is removed out of the protective
field, the LED2 is allowed to turn to yellow.

a = Beginning of test

Fig. 8.3-1: Testing the protective field with the test rod

✟ If the AOPD is being operated without the internal start/restart interlock, it is sufficient to

watch LED1 on the receiver during the testing procedure. When the test rod is inserted
into the protective field, this LED1 must switch from “green” to “red” and must not switch
back to “green” at any point during the test procedure.

DEUTSCHENGLISHFRANÇAISITALIANOESPAÑOLNEDERLANDS

Warning!

If the test does not yield the desired result, the cause could be a protective field height that
is too low or reflections from reflective metals or tools brought into the area. In this case the
installation of the safety light curtain must be checked by a specialist. If the cause cannot
be clearly defined and remedied, the machine or system must not beoperated any more!

8.4 Cleaning the front screens

The front screens on the transmitters and receivers must be cleaned regularly depending
on how dirty they are. A blinking 7-segment display with the protective field is free (LED1
is green) indicates a “weak signal reception”, cleaning is then required.

If cleaning the screens does not improve this, the detection range and alignment must be
checked.

We recommend using a mild cleanser for cleaning the front screens. The screens are
resistant to thinned acids or alkalis and resistant to organic solvents within limits.

9.3 AutoReset

After an error or a fault has been detected and displayed, an automatic restart occurs
within

• about 2 seconds for the transmitter

• about 10 seconds for the receiver
for the device in question. If the error or fault is no longer present at that time, the machine

or system can be started again.
For EDM errors (E 30) no AutoReset occurs. The Receiver Extended turns to a locking

state. Recovering is possible by removing the supply voltage and checking out the
contactors and wiring of the feed back loop. After the error has been eliminated, connect
the supply voltage again.

11.4 Checklists

The inspection before the initial operation determines the safety related integration of the
active opto-electronic protective device (AOPD) into the machine and its control. The
results of the inspection must be written down and kept with the machine documents.
They can then be used as a reference during the subsequent regular inspections.

11.4.1 Checklist for safeguarding danger points

SOLID-2 Safety Light Curtains (resolution 20 to 40 mm),
normal approach to the protective field

This checklist represents a help tool. It supports but does not serve for the inspection
before initial operation or the regular inspections by an expert.

• Is the safety distance calculated accordingly to the valid formula
for safeguarding danger points, considering the resolution and
the effective response time of the AOPD, the response time of a
possibly used safety interface and the stopping time of the
machine? Is this minimum distance between the protective field
and danger points considered?

• Is access to the danger point only possible through the protective
field of the AOPD and are other possible accesses protected by
suitable safety components?

• Is the protective field effective at each position and positively
checked according to Chapter

• Is reaching-over, reaching-under or reaching-around the protec­tive field effectively prevented, e.g. by mechanical measures
(welded or screwed)?

• Is unprotected presence between the protective field and danger
point safely excluded?

• Are transmitter and receiver fixed against displacement after the
alignment?

• Are the protective device and the control devices in good condi­tion?

• Are all connectors and connection cables in fault-free conditions? yes no

• Is the start/restart button for resetting the AOPD positioned outside
the danger zone and is it effective?

• Are the safety outputs (OSSDs), linked into the subsequent ma­chine control unit in accordance with the required safety category?

• Are the subsequent circuit elements controlled by the AOPD
monitored by the feedback circuit (EDM), e.g. contactors with
positive-guided contacts or safety valves?

• Does the actual integration of the AOPD into the machine control
unit match the circuit diagrams?

• Is the AOPD effective during the entire dangerous movement of the
machine?

• Is the dangerous movement stopped immediately if the supply
voltage of the AOPD is interrupted and is the start/restart button
required to start the machine again after the supply voltage
returns?

11.4.2 Checklist for safeguarding danger areas

DEUTSCH ENGLISH FRANÇAIS ITALIANO ESPAÑOL NEDERLANDS

For SOLID-2 Safety Light Curtain, parallel approach to the protective field
This checklist represents a help tool. It supports but does not serve for the inspection

before initial operation or the regular inspections by an expert.

• The minimum height of the protective field above the reference
plane relates to the resolution of the AOPD. Was the resolution
used during the calculation of the minimum height and is this result
considered?

• Has the safety distance been calculated according to the valid
formula for safeguarding danger areas and has this minimum
distance between the most distant beam and the danger point
been observed?

• During risk assessment, has it been ensured that only protective
field heights less than 300 mm above the floor are regarded as low
enough not to be crawled under (EN 999)?

• Is the access to the danger point only possible through the
protective field of the AOPD and are other access possibilities,
especially from the sides, protected by suitable hard guards or
other means?

• Is unprotected presence between the next beam and the danger
point definitively excluded?

• Are transmitter and receiver fixed against displacement/turning
after the alignment?

• Are the protective device and the control devices in good condi­tion?

• Are all connectors and connection cables in fault-free conditions? yes no

• Is the start/restart button for starting/restarting the AOPD positi­oned outside the danger zone and is it effective?

• Are the safety outputs (OSSDs), linked into the downstream
machine control in accordance with the required safety category?

• Are the downstream circuit elements controlled by the AOPD, e.g.
contactors with positive-guided contacts or safety valves, monito
red by the feedback circuit (EDM)?

• Does the actual integration of the AOPD into the machine control
unit match the circuit diagrams?

• Is the AOPD effective during the entire dangerous movement of the
machine?

• Is a possibly connected Section Emergency STOP button effective
and after its resetting, is pressing and releasing of the start/restart
button required to start the machine again?

*) For Safety Light Curtains with resolutions of 20, 30 or 40 mm, the appropriate test rod should be

moved up and down in the middle of the protective field. LED1 must stay “red” during the test and
must not switch to “green” at any point. For Receiver Extended with selected internal start/restart
interlock function the yellow LED2 must not switch to the ON state while the appropriate test rod is
present at any point of the protective field (see Chapter

8.3).
