Ä Before working with the safety sensor, completely read and observe the documents appli-

cable to your task.

In particular, the following national and international legal regulations apply for the commissioning, technical inspections and work with safety sensors:

• Machinery directive 2006/42/EC

• Low voltage directive 2014/35/EU

• EMC directive 2014/30/EU

• Use of work equipment directive 89/655/EEC supplemented by directive 95/63EC

• OSHA 1910 Subpart O

• Safety regulations

• Accident-prevention regulations and safety rules

• Ordinance on Industrial Safety and Health and employment protection act

• Product Safety Law (ProdSG and 9. ProdSV)

Safety

NOTICE

For safety-related information you may also contact local authorities (e.g., industrial inspectorate, employer's liability insurance association, labor inspectorate, occupational safety and health authority).

2.1 Intended use and foreseeable misuse

A running machine may result in serious injury!

WARNING

2.1.1 Intended use

Ä Make certain that the safety sensor is correctly connected and that the protective func-

tion of the protective device is ensured.

Ä Make certain that, during all conversions, maintenance work and inspections, the system

is securely shut down and protected against being restarted.

• The safety sensor may only be used after it has been selected in accordance with the respectively applicable instructions and relevant standards, rules and regulations regarding labor protection and safety at work, and after it has been installed on the machine, connected, commissioned, and checked by a competent person (see chapter 2.2 "Necessary competencies"). The devices are designed for indoor use only.

• When selecting the safety sensor it must be ensured that its safety-related capability meets or exceeds the required performance level PLr ascertained in the risk assessment (see chapter 14.1 "General specifications").

• The safety sensor protects persons or body parts at points of operation, danger zones or access points of machines and systems.

• With the “access guarding” function, the safety sensor detects persons only when they enter the danger zone but cannot tell whether there are any persons inside the danger zone. For this reason, a start/restart interlock or a suitable stepping behind protection in the safety chain is essential in this case.

• 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 inspected regularly by a competent person to ensure proper integration and mounting (see chapter 2.2 "Necessary competencies").

• The safety sensor must be exchanged after a maximum of 20 years. Repairs or the exchange of wear parts do not extend the mission time.

Protective field properties

The beam distance and the number of beams are dependent on the resolution and protective field height.

NOTICE

Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A) 9

Depending on the resolution, the effective protective field height can be larger than the optically active area of the safety sensor housed in yellow (see chapter 3.1 "Device overview of the SLC family" and see chapter 14.1 "General specifications").

Device description

Device synchronization

The synchronization of receiver and transmitter for creating a functioning protective field is done optically, i.e. without cables, via two specially coded synchronization beams. A cycle (i.e. a pass from the first to the last beam) is called a scan. The length of a scan determines the length of the response time and affects the calculation of the safety distance (see chapter 6.1.1 "Calculation of safety distanceS").

NOTICE

For the correct synchronization and function of the safety sensor, at least one of the two synchronization beams must be free during synchronization and operation.

Device model Device type Device plug

SLC-4TR Transmitter 5-pin

SLC-4SL Select receiver 8-pin

Host devices are also equipped with an interconnection cable, 400mm long, with M12 connector for connecting MiddleGuest or Guest devices.

MiddleGuest devices are equipped with two interconnection cables, 400mm long, with M12 connector for connecting Host or Guest devices.

Guest devices are equipped with an interconnection cable, 400mm long, with M12 connector for connecting Host or MiddleGuest devices.

3.3 Cascading

To implement linked protective fields, up to three SLC safety light curtains can be cascaded one after the other.

Adjacent protective fields, e.g., for stepping behind protection, can thereby be implemented without any additional expense for control and connection. The host system performs all necessary processor tasks, provides indicators and the receiver-side interfaces to the machine and command devices.

Devices with different resolutions can be combined. With mounting brackets (see chapter 15 "Order guide and accessories"), an L or U-shaped

fixed connection can be created.

For error diagnostics, the error's respective letter is displayed first followed by the number code. The display is repeated cyclically. An AutoReset is carried out after 10s for errors that do not cause locking, with an unauthorized restart being impossible. In the case of blocking errors, the voltage supply must be separated and the cause of the error must be eliminated. Before switching on again, the steps taken before initial commissioning must be repeated (see chapter 9.1 "Before the initial start-up and following modifications").

The 7-segment display switches to alignment mode when the device has not yet been aligned or when the protective field has been interrupted (after 5s). In this case, a fixed beam area from the protective field is assigned to every segment.

Functions

4 Functions

An overview of features and functions of the safety sensor can be found in chapter “Device description” (see chapter 3.1 "Device overview of the SLC family").

Overview of functions

• Start/restart interlock (RES)

• EDM

• Range reduction

• Transmission channel changeover

4.1 Start/restart interlock RES

After accessing the protective field, the start/restart interlock ensures that the safety sensor remains in the OFF state after the protective field has been cleared. It prevents automatic release of the safety circuits and automatic start-up of the system, e.g. if the protective field is again clear or if an interruption in the voltage supply is restored.

NOTICE

WARNING

NOTICE

DANGER

For access guarding, the start/restart interlock function is mandatory. The protective device may only be operated without start/restart interlock in certain exceptional cases and under certain conditions acc. to ENISO12100.

Deactivation of the start/restart interlock may result in serious injury!

Ä Implement the start/restart interlock on the machine or in a downstream safety circuit.

Using start/restart interlock

Ä Wire the SLC-4SL receiver appropriately for the desired operating mode (see chapter 7

"Electrical connection"). The start/restart interlock function is automatically activated. Switching the safety sensor back on after shutting down (OFF state):

Ä Press the reset button (Press/Release between 0.1s and 4s)

The reset button must be located outside the danger zone in a safe place and give the operator a good view of the danger zone so that he/she can check whether anyone is located in it (according to EN62046) before pressing the reset button.

Risk of death if start/restart is operated unintentionally!

Ä Ensure that the reset button for unlocking the start/restart interlock cannot be reached

from the danger zone.

Ä Before unlocking the start/restart interlock, make certain that no people are in the danger

zone.

After the reset button has been actuated, the safety sensor switches to the ON state.

4.2 EDM contactor monitoring

NOTICE

Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A) 16

The contactor monitoring of theSLC-4SL safety sensors can be activated through appropriate wiring (see chapter 7.1.1 "SLC-4TR transmitter")!

The “contactor monitoring” function monitors the contactors, relays or valves connected downstream of the safety sensor. Prerequisite for this are switching elements with positiveguided feedback contacts (normal closed contacts).

Functions

Implement the contactor monitoring function:

• through appropriate wiring of the SLC-4SL safety sensors (see chapter 7.1.1 "SLC-4TR transmitter").

• through the external contactor monitoring of the downstream safety relay, (e.g. samosPRO from Wieland Electric)

• or through contactor monitoring of the downstream safety PLC (optional, integrated via a safety bus)

If contactor monitoring is activated (see chapter 7 "Electrical connection"), it operates dynamically, i.e., in addition to monitoring the closed feedback circuit every time before the OSSDs are switched on, it also checks whether the release of the feedback circuit opened within 500 ms and, after the OSSDs are switched off, whether it has closed again within 500 ms. If this is not the case, the OSSDs return to the OFF state after being switched on briefly. An error message appears on the 7-segment display (E30, E31) and the receiver switches to the fault interlock state from which it can only be returned to normal operation by switching the supply voltage off and back on again.

4.3 Transmission channel changeover

Transmission channels are used to prevent mutual interference of safety sensors which are located close to each other.

NOTICE

To guarantee reliable operation, the infrared beams are modulated so they can be discerned from the ambient light. Welding sparks or warning lights, e.g. from passing high-lift trucks, thereby do not influence the protective field.

With the factory setting, the safety sensor works in all operating modes with transmission channelC1.

The transmission channel of the transmitter can be switched by changing the supply voltage polarity (see chapter 7.1.1 "SLC-4TR transmitter").

The transmission channel of the receiver can be switched by changing the supply voltage polarity (see chapter 7.1.2 "SLC-4SL receiver").

Faulty function due to incorrect transmission channel!

Select the same transmission channel on the transmitter and corresponding receiver.

4.4 Range reduction

In addition to selecting the suitable transmission channels (see chapter 4.3 "Transmission channel changeover"), the range reduction also serves to prevent mutual interference of adjacent safety sensors. Activating the function reduces the light power of the transmitter so that around half of the nominal range is reached.

Reducing range:

Ä Wire pin4 (see chapter 7.1 "Pin assignment transmitter and receiver"). ð The wiring of pin4 determines the transmitting power and thereby the range.

Impairment of the protective function due to incorrect transmitting power!

The light power emitted from the transmitter is reduced through a single channel and without safety-relevant monitoring.

WARNING

Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A) 17

Ä Do not use this configuration option for safety purposes. Ä Note that the distance to reflective surfaces must always be selected so that no reflection

bypass can occur even at maximum transmitting power (see chapter 6.1.4 "Minimum distance to reflective surfaces").

Applications

5 Applications

The safety sensor only creates square protective fields.

5.1 Point of operation guarding

Point of operation guarding for hand and finger protection is typically the most common application for this safety sensor. In accordance with ENISO13855, resolutions from 14to40mm make sense here. This yields the necessary safety distance, among others (see chapter 6.1.1 "Calculation of safety distanceS").

Fig.5.1: Point of operation guarding protects reaching into the danger zone, e.g. for car-

toners or filling systems

Fig.5.2: Point of operation guarding protects reaching into the danger zone, e.g. for a

pick&place robot application

Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A) 18

Applications

5.2 Access guarding

Safety sensors with up to 90mm resolution are used for access guarding into danger zones. They detect people only upon entry into the danger zone, i.e., they do not detect parts of a person or whether a person is present in the danger zone.

Fig.5.3: Access guarding on a transfer path

5.3 Danger zone guarding

Safety light curtains can be used in horizontal arrangement for danger zone guarding - either as stand-alone device for presence monitoring or as stepping behind protection for presence monitoring e.g. in combination with a vertically-arranged safety sensor.

WARNING

Mounting

6 Mounting

Improper mounting may result in serious injury!

The protective function of the safety sensor is only ensured if appropriately and professionally mounted for the respective, intended area of application.

Ä Only allow the safety sensor to be installed by qualified persons (see chapter 2.2 "Neces-

sary competencies").

Ä Maintain the necessary safety distances (see chapter 6.1.1 "Calculation of safety dis-

tanceS").

Ä Make sure that stepping behind, crawling under or stepping over the protective device is

reliably ruled out and reaching under, over or around is taken into account in the safety distance, if applicable with additional distanceCRO corresponding to ENISO13855.

Ä Take measures to prevent that the safety sensor can be used to gain access to the danger

zone, e.g. by stepping or climbing into it.

Ä Observe the relevant standards, regulations and these instructions. Ä Clean the transmitter and receiver at regular intervals: environmental conditions (see

chapter 14 "Technical data"), care (see chapter 10 "Maintenance").

Ä After mounting, check the safety sensor for proper function.

6.1 Arrangement of transmitter and receiver

Optical protective devices can only perform their protective function if they are mounted with adequate safety distance. When mounting, all delay times must be taken into account, such as the response times of the safety sensor and control elements as well as the stopping time of the machine, among others.

The following standards specify calculation formulas:

• IEC61496-2, "Active optoelectronic protective devices": distance of the reflecting surfaces/deflecting mirrors

• EN13855, "Safety of machines - The positioning of protective equipment in respect of approach speeds of parts of the human body": mounting situation and safety distances

NOTICE

6.1.1 Calculation of safety distanceS

In accordance with ISO13855, with a vertical protective field, it is possible to pass under beams over 300mm or pass over beams under 900mm. If the protective field is horizontal, climbing on the safety sensor must be prevented through suitable installation or with covers and the like.

General formula for calculating the safety distanceS of an Optoelectronic Protective Device acc. to ENISO13855

S [mm] = Safety distance K [mm/s] = Approach speed T [s] = Total time of the delay, sum from (ta+ti+tm) t

[s] = Response time of the protective device

[s] = Response time of the safety relay

[s] = Stopping time of the machine

C [mm] = Additional distance to the safety distance

NOTICE

Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A) 20

If longer stopping times are determined during regular inspections, an appropriate additional time must be added to tm.

Mounting

6.1.2 Calculation of safety distance if protective fields act orthogonally to the approach direction

With vertical protective fields, ENISO13855 differentiates between

• SRT: safety distance concerning access through the protective field

• SRO: safety distance concerning access over the protective field

The two values are distinguished by the way additional distanceC is determined:

• CRT: from a calculation formula or as a constant (see chapter 6.1.1 "Calculation of safety distanceS")

• CRO: from the following table “Reaching over the vertical protective field of electro-sensitive protective equipment (excerpt from ENISO13855)”

The larger of the two values SRT and SRO is to be used.

Calculation of safety distanceSRT acc. to ENISO13855 when access occurs through the protective field:

Calculation of safety distanceSRT for point of operation guarding

SRT[mm] = Safety distance K [mm/s] = Approach speed for point of operation guarding with approach reaction and

normal approach direction to the protective field (resolution 14to40mm):

2000mm/s or 1600mm/s, when SRT>500mm T [s] = Total time of the delay, sum from (ta+ti+tm) t

[s] = Response time of the protective device

[s] = Response time of the safety relay

[s] = Stopping time of the machine

CRT[mm] = Additional distance for point of operation guarding with approach reaction

with resolutions of 14to40mm, d=resolution of protective device

CRT=8×(d-14)mm

Calculation example

The feeding-in area in a press with a stopping time (including press Safety PLC) of 190ms is to be safeguarded with a safety light curtain with 20mm of resolution and 1200mm of protective field height. The safety light curtain has a response time of 22ms.

Ä Calculate safety distanceSRT using the formula acc. to ENISO13855.

K [mm/s] = 2000 T [s] = (0.022+0.190) CRT[mm] = 8×(20-14) SRT[mm] = 2000mm/s×0.212s+48mm S RT[mm] = 472

SRT is smaller than 500mm; this is why the calculation may not be repeated with 1600mm/s.

NOTICE

[s] = Response time of the protective device

[s] = Response time of the safety relay

14)mm. Additional distance for access guarding for resolutions>40mm:

CRT=850mm (standard value for arm length)

Calculation example

Access to a robot with a stopping time of 250ms is to be safeguarded with a safety light curtain with 90mm of resolution and 1500mm of protective field height whose response time is 6ms. The safety light curtain directly switches the contactors whose response time is contained in the 250ms. An additional interface therefore does not have to be taken into consideration.

Ä Calculate safety distanceSRT using the formula acc. to ENISO13855.

NOTICE

K [mm/s] = 1600 T [s] = (0.006+0.250) CRT[mm] = 850 SRT[mm] = 1600mm/s×0.256s+850mm S RT[mm] = 1260

This safety distance is not available in the application. This is why a new calculation is done with a safety light curtain with 40mm of resolution (response time=14ms):

Ä Re-calculate safety distanceSRT using the formula acc. to ENISO13855.

K [mm/s] = 1600 T [s] = (0.014+0.250) CRT[mm] = 8×~(40-14) SRT[mm] = 1600mm/s×0.264s+208mm S RT[mm] = 631

The safety light curtain with a 40mm resolution is thus suitable for this application.

For the calculation with K=2000mm/s, safety distanceSRT equals 736mm. The adoption of approach speed K=1600mm/s is therefore permitted.

6.2.2 Definition of directions of movement

The following terms for alignment movements of the safety sensor around one of its axes are used:

a Sliding: movement along the longitudinal axis b Turning: movement around the longitudinal axis c Tilting: lateral turning movement diagonal to the front screen d Pitching: lateral turning movement in the direction of the front screen

6.2.3 Fastening via SLX-MO-TNUTM6 sliding blocks

By default, transmitter and receiver are delivered with 2SLX-MO-TNUTM6 sliding blocks each in the side slot. This makes fastening the safety sensor to the machine or system to be safeguarded easy via four M6 screws. Sliding in the direction of slot to set the height is possible, but turning, tilting and pitching is not.

Mounting

6.2.4 Fastening via swivel mount SLX-MO-RO2

With the swivel mount (see chapter 15 "Order guide and accessories"), sold separately, the safety sensor can be aligned as follows:

• Sliding through the vertical threaded holes in the wall plate of the swivel mount

• Turning by 360° around the longitudinal axis by fixing on the screw-on cone

• Pitching in the direction of the protective field with horizontal threaded holes in the wall mounting

• Tilting around main axis

The wall mounting through threaded holes makes it possible to lift the mounting bracket after the screws have been loosened over the connection cap. Therefore, the mounting brackets do not need to be removed from the wall when exchanging the device. Loosening the screws is sufficient.

For increased mechanical loads, mounting brackets are also available in a vibration-damped version (SLX-MO-RO2S) (see chapter 15 "Order guide and accessories").

brackets is recommended (see chapter 15 "Order guide and accessories"). For increased mechanical requirements, these are also available as vibration-damped version (SLX-MO-2RO3S). Depending on the installation situation, environmental conditions and protective field length (> 1200 mm), other mounting brackets may also be necessary.

Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A) 32

6.2.6 One-sided mounting on the machine table

The safety sensor can be mounted directly on the machine table via an M5 screw on the blind hole in the end cap. On the other end, a SLX-MO-RO2 swivel mount can be used, for example, so that turning movements for alignment are possible despite the fact that the sensor is mounted on one side. The full resolution of the safety sensor is thus preserved on all points of the protective field down to the machine table.

6.3.1 SLC-PRO protective screen

If there is a risk that the protective plastic screens of the safety sensors could get damaged, e.g. by welding sparks, placing the additional, easy-to-replace SLC-PRO protective screen in front of the safety sensors can protect the device protective screen and considerably increase the availability of the safety sensor. Mounting is performed using special clamp brackets, which are fastened on the lateral slot, via an Allen screw accessible from the front on each. The range of the safety sensor is reduced by approx.5%; when protective screens are used on the transmitter and the receiver it is reduced by 10%. Mounting bracket sets with 2and 3clamp brackets are available.

Mounting

NOTICE

If the length equals 1200mm or higher, 3clamp brackets are recommended.

Starting up the device

8 Starting up the device

Improper use of the safety sensor may result in serious injury!

Ä Make certain that the entire device and the integration of the optoelectronic protective

device were inspected by qualified and instructed persons (see chapter 2.2 "Necessary competencies").

Ä Make certain that a dangerous process can only be started while the safety sensor is

switched on.

Prerequisites:

• Safety sensor mounted (see chapter 6 "Mounting") and connected (see chapter 7 "Electrical connection") correctly

• Operating personnel were instructed in proper use

• Dangerous process is switched off, outputs of the safety sensor are disconnected, and the system is protected against being switched back on

Ä After start-up, check the function of the safety sensor (see chapter 9.1 "Before the initial

start-up and following modifications").

Requirements for the supply voltage (power supply unit):

• Reliable mains separation is ensured.

• Current reserve of at least 2A is available.

• The RES function is activated - either in the safety sensor or in the downstream control.

Ä Switch on the safety sensor. ð The safety sensor performs a self test and then displays the response time of the receiver

(see chapter 3.4.2 "Operation indicators on the SLC-4SL receiver").

Check operational readiness of sensor

Ä Check whether LED1 is permanently lit green or red (see chapter 3.4.2 "Operation indica-

tors on the SLC-4SL receiver").

ð The safety sensor is ready for use.

8.2 Aligning the sensor

NOTICE

Faulty or incorrect alignment may result in an operating fault!

Ä The alignment performed during start-up should only be performed by qualified persons

(see chapter 2.2 "Necessary competencies").

Ä Observe the data sheets and mounting instructions of the individual components.

Prealignment

Fasten the transmitter and receiver in a vertical or horizontal position and at the same height so that

• the front screens are directed at each other.

• the transmitter and receiver connections point in the same direction.

• the transmitter and receiver are arranged parallel to each other, i.e. they are the same distance from each other at the beginning and end of the device.

Alignment can be performed with a clear protective field by observing the LEDs and the 7-segment display (see chapter 3.4 "Display elements").

Ä Loosen the screws on the mounting brackets or device columns.

NOTICE

Wieland Electric GmbH | BA001133 | 04/2017 (Rev. A) 38

Loosen the screws only enough so that the devices can just be moved.

Starting up the device

Ä Turn the receiver to the left until LED1 still flashes green but does not yet illuminate red. If

necessary, you may have to turn the transmitter beforehand.

ð The receiver with activated alignment display shows flashing segments in the 7-seg-

ment display.

Ä Now align the transmitter according to the same method, paying attention to the display

elements of the receiver while doing so (see chapter 3.4.2 "Operation indicators on the SLC-4SL receiver").

NOTICE

Separate alignment aids are also available as accessories.

8.3 Aligning of deflecting mirrors with the laser alignment aid

When using deflecting mirrors for multiple-side point of operation guarding and access guarding, an external laser alignment aid is recommended (see chapter 15 "Order guide and accessories").

NOTICE

With its clearly visible red light spot, the external laser alignment aid facilitates the correct setting of the transmitter and receiver as well as the deflecting mirrors.

Ä Fasten the laser alignment aid on top on the side groove of the transmitter. Mounting in-

structions are included in the accessories.

Ä Switch on the laser. Take note of the operating instructions of the laser alignment aid con-

cerning the safety notices and the activation of the laser alignment aid.

Ä Loosen the mounting bracket of the transmitter and turn or tilt or pitch the device so that

the laser spot strikes the top of the first deflecting mirror (see chapter 6.2.2 "Definition of directions of movement").

Ä Now set the laser below on the transmitter and adjust it so that the laser spot strikes the

bottom of the deflecting mirror.

Ä Now set the laser back up top on the transmitter and check if the laser spot still strikes the

top of the deflecting mirror. If it does not, the mounting height of the transmitter must be changed, if applicable.

Ä Repeat the process until the laser strikes the respective point of the deflecting mirror, both

on top and on bottom.

Ä Turn, tilt or pitch the deflecting mirror so that the laser spot strikes either the next deflect-

ing mirror or the receiver in both positions.

Ä Repeat the process in reverse after setting the laser alignment aid above and below on the

receiver. The laser beam must strike the transmitter in both cases if the receiver has been correctly aligned.

Ä Remove the laser alignment aid from the safety sensor. ð The protective field is free. LED1 on the receiver is permanently lit green. The OSSDs

switch on.

8.4 Unlocking start/restart interlock

The reset button can be used to unlock the start/restart interlock. In this way, the responsible person can restore the ON state of the safety sensor following process interruptions (due to triggering of protective function, failure of the voltage supply).

Premature unlocking of the start/restart interlock may result in serious injury!

If the start/restart interlock is unlocked, the system can start up automatically.

Ä Before unlocking the start/restart interlock, make certain that no people are in the danger

Safety-related PNP transistor out-

Minimum Typical Maximum puts (short-circuit monitored, cross-circuit monitored)

OSSD restart delay time after beam interruption

a) In the event of a failure (if the 0V cable is interrupted), each of the outputs behaves as a 120kΩ resistor to Uv. A downstream safety PLC must not detect this as a logical "1".

b) Note the additional restrictions due to cable length and load current.

NOTICE

The safety-related transistor outputs perform the spark extinction. With transistor outputs, it is therefore neither necessary nor permitted to use the spark extinction circuits recommended by contactor or valve manufacturers (RC elements, varistors or recovery diodes), since these considerably extend the decay times of inductive switching elements.
