3.1 The opto-electronic protective device

Mode of operation
SOLID-4 consists of an SD4T transmitter and an SD4R 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.
a = Transmitter b = Receiver
Fig. 3.1-1: Working principle of the opto-electronic protective device
The SD4R receiver recognizes the specially f and opens the corresponding receiver elements in sequence in the same rhythm. A protective field is consequently formed in the area between the transmitter and receiver, the height of which depends on the geometrical dimensions of the optical protective device, the width of which depends on the distance selected between the transmitter and receiver within the permissible range.
Basic functions, such as start/restart interlock be performed by the electronics of receiver model SD4R-E. As a result, no downstream Safety Interface Device is generally necessary if receiver model SD4R-E is chosen.

The infrared beams are modulated with specially shaped pulse bundles so that they are distinct from ambient light and undisturbed operation is consequently ensured. 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 measures must, however, be implemented so that the optical protective devices do not affect each other.
Both transmitters should first be set up "back to back" so that the beams run in opposite direct

Attention!
Without start/restart interlock, the outputs of the receiver switch to the ON state immedi­ately after the device is switched on or afte each release of the protective field!

4.4 Diagnostics function: Dirt and error signal output

For diagnostic purposes SOLID-4 has a short circuit-proof "Weak Beam/Error Indication" signal output for forwarding to the machine control unit. Information on connection of the signal output and a connection example can be found in Chapter 7.

4.5 Test input

As a type 4 AOPD, SOLID-4 has a constant self-monitoring function that independently detects errors in the system as well as cross and short circuits on the output cables of the machine interface. An external test signal is not required for this. To test the downstream contactors, an external control (e.g. protective combination) via a test signal (= pin4 of the transmitter to 0 V or free) can switch off the OSSD outputs of the receiver and test the drop­out
of
the switching elements. The test time signal time is a maximum 3 seconds. After the test the OSSDs also go to the ON-state with activated start/restart interlock, provided the protective field is not interrupted.

8.2 Aligning transmitter and receiver

Transmitter and receiver must be at the same height or, if installed in a horizontal position, be at the same distance from the reference surface and lightly fastened at first. The narrow specified angle of beam spread of ± 2° requires increased precision in aligning the two components with each other before the devices are screwed firmly into place.
Note!
If cascaded AOPDs are aligned with each other, it must then guest.

If the components are already aligned, it is recomm e.g. by turning the receiver. Turn the receiver with slightly loosened brackets until the 7­segment display starts to flash. Take note of the position. Now turn the receiver in the opposite direction until the display lights constantly and further, until it flashes again. Now turn the receiver back in between the two positions determined. Screw the receiver firmly into place to prevent turning. Now do the same with the transmitter.
For cascaded systems, the procedure can be performed for all transmitters and receivers one af

9 Testing

9.1 Testing before first startup

Testing by an experienced technician before first startup must ensure that the optical protective device and any other safety components that might be present have been selected in accordance with local regulations and applicable European Directives, espe­cially the European Machine and Work Equipment required protection when properly operated.
➢ Use the regulations listed above, where required,
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 (point of operation, danger zone or access guarding).
➢ T
he same testing requirements apply if the machine in question has not been operated
f
or 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 i
enced technicians before work is started. Instruct machine owner.
The results of this test are documented for the machine owner in accordance with ISO
9000 ff.

9.2 Regular tests

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

9.3 Daily testing with the test rod

SOLID-4 are self-monitoring Safety Light Curtains. Nevertheless it is very important to check the effectiveness of the protective field every day to be sure that the protection also remains effective at every point after a parameter or tool change.
Warning!
Never use your fingers, hand or arm for checking the system!

information as a guideline.
➢ If the internal start/restart interlock function is selected, but the AOPD is released, LED1

ights up green on the SD4R-E Receiver. When the test rod is inserted, LED1 switches to red, and the restart interlock locks. During the testing procedure, LED2 must not light up at any position of the protective field. Only after the test rod has been taken out of the protective field does LED2 light up yellow (restart interlock locked).

f the AOPD is being operated without the internal start/restart interlock, it is sufficient to wat
ch 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.
Warning!
If the test does not provide the desired result, the cause could be a protective field height t
is too low or reflections from reflective metals or tools brought into the area. In this
hat 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 may not be used!

9.4 Cleaning the front screens

The front screens on the transmitters and receivers must be cleaned regularly depending on how dirty they are. A flashing 7-segment display with the protective field free (LED1 is green) indicates a "weak signal reception"; cleaning the front screen is then required. If cleaning the screens does not improve this, the range and alignment must be checked. We recommend using a mild cleanser for cleaning the Plexiglas front screens. The screens are resistant to diluted acids or alkalis and resistant to organic solvents within limits.

12.4 Checklists

The inspection before first startup determines the safety-related flawless integration of the active opto-electronic protective device (AOPD) into the machine and its control system. The results of the inspection must be recorded in writing and kept with the machine documents. They can then be used as a reference during subsequent regular inspections.

12.4.1 Checklist for point of operation guarding

For a SOLID-4 Safety Light Curtain (resolution 14 mm to 40 mm), with normal approach to the protective field.
This checklist is intended as a help tool. It supports but does not replace the inspection before first startup or the respective regular inspections by an expert.
• Is the safety distance calculated in accordance with the valid formulas for poin
t of operation guarding, while taking the effective resolution and the response time of the AOPD, the response time of a possibly used safety interface and the stopping time of the machine into consideration, and has this minimum distance between the protective field and the point of operation been observed?
• Is access to the point of operation only possible through the protective field of
he AOPD and are other possible accesses protected by suitable safety

12.4.2 Checklist for danger zone guarding

For a SOLID-4 Safety Light Curtain with parallel approach to the protective field
This checklist is intended as a help tool. It supports but does not replace the inspection before first startup or the respective 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 when calculating the
minimum height and is this height ensured?
• Is the safety distance calculated in acc for danger zone guarding and is this minimum distance between the most distant effective beam and the point of operation observed?
• During risk assessment, has it been ensured that only protective field height
s
less than 300 mm above the floor are regarded as low enough not to
be crawled under (EN 999)?
• Is the access to the point of operation only possible through the protective f
i
eld 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 point of operation def
