2. General Precautions

ENGLISH

English

•Verify that this device is operating normally in terms of functionality and performance before the start of work and before the start of device operation.

• KEYENCE is unable to warrant the function or performance of the SL-R12EX if it is used in a manner that differs from the SL-R12EX specifications contained in this instruction manual or if the SL-R12EX is modified.

• When using the SL-R12EX to protect machine operators from a hazardous zone or a hazard, or using it as safety equipment for any purpose, always follow the applicable requirements, regulations, and laws (collectively “regulations”) existing in the country or region where the SL-R12EX is being used. For such regulations, contact directly the regulatory agency responsible for occupational safety and health in your country or region.

• Depending on the type of machine to which the SL-R12EX is to be attached, there may be special safety regulations related to the use, installation, maintenance, and operation of the device, and such safety regulations must be followed. The responsible personnel must install the SL-R12EX in strict compliance with such safety regulations.

• The responsible personnel must train the assigned personnel for the correct use, installation, maintenance, and operation of the SL-R12EX. “Machine operators” refers to personnel who have received appropriate training from the responsible personnel and are qualified to operate the device correctly.

• Machine operators must receive specialized training for the SL-R12EX and must understand and follow the safety regulations for the country or region in which they are using the SL-R12EX.

• When the SL-R12EX fails to operate properly, machine operators must immediately stop the use of the device and report this fact to the responsible personnel.

• The SL-R12EX is designed with the assumption that it would be properly installed in accordance with the installation procedures described in this instruction manual and operated according to the instructions in this instruction manual. Perform an appropriate installation of the SL-R12EX after conducting a sufficient risk assessment for the target machine.

• This device should be processed as an industrial waste product when being disposed.

3. Warning

■ Operators

• In order for the SL-R12EX to operate properly, the responsible personnel and machine operators must

follow all procedures described in this instruction manual.

• No person other than the responsible personnel and machine operators should be allowed to install or

test the SL-R12EX.

• When performing electrical wiring, always follow electrical standards and regulations for the country or

region in which the SL-R12EX is being used.

■ Usage environment

• Do not use the device in an environment (temperature, humidity, interfering light, etc.) that does not

conform to the specifications contained in this instruction manual.

• Do not use wireless devices such as cellular phones or transceivers in the vicinity of the SL-R12EX.

• The SL-R12EX is not designed to be explosion-proof. Never use it in the presence of flammable or

explosive gases or elements.

• Do not use the SL-R12EX in the presence of substances, such as heavy smoke, particulate matter, or

corrosive chemical agents, that may induce deterioration in product quality.

■ Target machine

• The SL-R12EX has not undergone the model certification examination in accordance with Article 44-2

of the Japanese Industrial Safety and Health Law. The SL-R12EX, therefore, cannot be used in Japan as a “Safety Device for Press and Shearing machines” as established in Article 42 of that law.

• The machine on which the SL-R12EX is to be installed must be susceptible to an emergency stop at all

operating points during its operation cycle. Do not use the SL-R12EX for machines with irregular stop times.

• Do not use the SL-R12EX for power presses equipped with full-revolution clutches.

• Do not use the SL-R12EX to control (stop forward motion, etc.) trains, cars and other transportation

vehicles, aircraft, equipment for use in space, medical devices, or nuclear power generation systems.

• The SL-R11 is designed to protect people or objects from entering a machine’s hazardous zone or

hazard. It cannot provide protection against objects or materials that are displaced from the machine's hazardous zone or hazard, and so implement additional safety measures such as installing safeguards when there is the possibility of such displacements.

■ Installation

• Install the SL-R12EX inside an enclosure such as a control panel that offers a rating of at least IP54 in

accordance with the IEC 60529 standard.

• The SL-R12EX is a special controller unit for the Safety Light Curtain SL-C Series and the Intelligent

Safety Relay Unit SL-R11, so be sure to connect it to the SL-C Series and SL-R11 when using it.

• The SL-C**L Series with the detection capability of ø45 mm (1.77") cannot be used in combination with

the SL-R12EX.

■ Function

• When floating blanking function is carried out, the SL-C series cannot keep the original detection

capability. The detection capability of the SL-C**F Series varies among ø14 mm (0.55"), ø24 mm (0.94"), ø34 mm (1.33"), and ø44 mm (1.73") according to the exact settings used. The detection capability of the SL-C**H Series varies among ø25 mm (0.98"), ø45 mm (1.77"), ø65 mm (2.56"), and ø85 mm (3.35") according to the exact settings used. Therefore you must accurately calculate the new safety distance and install the SL-C Series at the minimum safety distance separately from the hazardous zone or hazards.

• When fixed blanking function is carried out, it may create a hazardous zone allowing human approach

between the obstacle and the SL-C Series against which the SL-C Series provides no protection. Be sure to install additional safety protective equipment.

• Enabling the blanking blind protection function does not necessarily remove all hazardous zones

allowing human approach. Depending on the target machine, installation of the blanking blind protection unit may result in the creation of one or more hazardous zones allowing human approach. Be sure to read “4-4 Blanking blind protection function” (➮4-4) in this manual before installing or using this unit. This function can only be used in the SL-C**H Series with the detection capability of ø25 mm (0.98").

• The muting function deactivates the light curtain's safety functions while the light curtain detects the

input signal from one or more muting devices (sensors, switches, etc.). The muting devices (sensors, switches, etc.) that are used to carry out the muting function as well as the method to install them must satisfy all the conditions described in this instruction manual as well as the applicable requirements imposed by all laws, regulations, standards, and ordinances in effect in the country and region where the SL-R12EX is to be used. Failure to follow this warning results in significant harm to machine operators, including serious injury or death.

ENGLISH

Page 6

• The following conditions must be considered before installing muting devices (sensors, switches, etc.) to

carry out the muting function.

1. The muting function of the light curtain is only permitted during the nonhazardous portion of the machine cycle.

2. Muting devices must not get active and the light curtain (SL-C Series) must not go to the muting state even if a person inadvertently approaches the light curtain's detection zone.

• Setting the muting function and muting device configuration must be restricted to an extremely limited number of the responsible personnel.

• Any personnel other than the responsible personnel must not easily change the position at which the muting devices are installed. When the muting devices are moved, the procedure must require the use of specialized tools and must be performed under the responsibility of the responsible personnel.

• Customers who carry out the muting function bear sole responsibility for complying with the requirements imposed on that function. KEYENCE makes no guarantee regarding damage arising from installation, orientation, usage, or maintenance not in accordance with what is described in this instruction manual, or from the failure to follow all applicable legal regulations in effect in the country and region in which the SL-R12EX is used.

• The muting lamp or the SL-R12D must be installed prior to carrying out the muting function on the SL-C Series. The muting lamp or the SL-R12D must be installed at the location where it can always be clearly and easily visible for the machine operators or the responsible personnel in case of normal machine operation, setting or alignment for muting or maintenance, etc.

• If it is necessary to install 2 or more muting lamps in order to satisfy the above requirements, the muting lamps must be installed so that they are connected in series to the LAMP terminal on the SL-R12EX terminal block. The SL-R12D cannot be used with the other muting lamps simultaneously. Therefore, the other muting lamps must be installed instead of using the SL-R12D.

ENGLISH

English

4. Circuit Design and Wiring

• Always turn off the device power when performing electrical wiring.

• Follow electrical standards and regulations for the country or region in which the SL-R12EX is being used when performing the electrical wiring. Only qualified persons should perform wiring.

• Do not place any cables or electrical lines used in wiring the SL-R12EX in the same duct as high-voltage electrical or power lines or in parallel with such lines.

• The length of the cables from the blanking blind protection unit (SL-C08SB/SL-C16SB) transmitter and receiver to the SL-R12EX must not exceed 30 m (98.43 ft.).

5. Testing and Maintenance

• Always perform testing in accordance with the test procedures after maintenance, adjustment, or calibration of the target machine or the SL-R12EX, and before the machine start-up.

• If the SL-C, SL-R11 or SL-R12EX does not operate properly when tested in accordance with the test procedures established in this instruction manual, do not operate the machine.

• Periodically examine the machine to verify that all brakes, other stop mechanisms, and control devices operate reliably and accurately in addition to checking for SL-C, SL-R11 and SL-R12EX.

• The responsible personnel must perform maintenance procedures as established in this instruction manual at least once every six months to ensure safe device operation.

2 Functions

2-1 Foreword

This section describes the functions that are provided by the SL-R12EX. These functions allow you to configure various settings related to the detection performance of the SL-R11 and SL-C Series devices that are connected to the SL-R12EX and can be set for individual SL-C Series beam axes. For this reason, references throughout this text to “detection capability” and “beam axes” should be understood to refer to the detection capability and beam axes of the SL-C Series.

2-2 Floating blanking function

When this function is carried out, the SL-C series cannot keep the original

WARNING

detection capability. The detection capability of the SL-C**F Series varies among ø14 mm (0.55"), ø24 mm (0.94"), ø34 mm (1.33"), and ø44 mm (1.73") according to the exact settings used. The detection capability of the SL-C**H Series varies among ø25 mm (0.98"), ø45 mm (1.77"), ø65 mm (2.56"), and ø85 mm (3.35") according to the exact settings used. Therefore you must accurately calculate the new safety distance and install the SLC Series at the minimum safety distance separately from the hazardous zone or hazards. When installing the SL-C Series onto/into a machine, always follow the instructions in the SL-C Series Instruction Manual. Failure to follow this warning may result in significant harm to machine operators, including serious injury or death.

Normally, the FSD turns OFF-state when an obstacle blocks even a single SL-C Series beam axis. When this function is enabled, the FSD keeps ON-state in the event that only a preset number (between 1 and

3) of beam axes are blocked. Only when the number of beam axes blocked by the objects exceeds that preset number, the FSD turns OFF-state. In order to carry out this function, the SL-C Series need not be a single transmitter/receiver pair. This function can be set for all beam axes on all SL-C Series units connected in series. (See the right diagram.) See “4-2 Floating blanking function” (➮4-2) for more information about how to set or configure this function. This function can be configured in one of three ways, as indicated below.

: Zone where floating blanking function is active

2-2-1 Floating blanking for 1 beam axis

The FSD keeps ON-state when only 1 beam axis is blocked, and turns OFF-state when 2 or more beam axes are blocked. Note that for the SL-C**F Series the detection capability is ø24 mm (0.94"), and for the SLC**H Series the detection capability is ø45 mm (1.77").

2-2-2 Floating blanking for 2 beam axes

The FSD keeps ON-state when 1 or 2 beam axes are blocked, and turns OFF-state when 3 or more beam axes are blocked. Note that for the SL-C**F Series the detection capability is ø34 mm (1.33"), and for the SLC**H Series the detection capability is ø65 mm (2.56").

2-2-3 Floating blanking for 3 beam axes

The FSD keeps ON-state when 1, 2, or 3 beam axes are blocked, and turns OFF-state when 4 or more beam axes are blocked. Note that for the SL-C**F Series the detection capability is ø44 mm (1.73"), and for the SL-C**H Series the detection capability is ø85 mm (3.35").

2-3 Fixed blanking function

ENGLISH

English

WARNING

Normally, the FSD keeps the ON-state only when all beam axes are clear of any obstruction (that is, when there are no obstacles present in the detection zone). The Fixed blanking function is enabled only for the beam axes in the zone initially specified by the user and allows the FSD to keep ON-state when an obstacle blocks the beam axes in that zone. For example, if an obstacle blocks the beam axes of the SL-C Series, the FSD turns OFF-state (see the right diagram.) In contrast, if the light curtain is configured to enable fixed blanking, the FSD keeps ONstate when an obstacle blocks these pre-set beams. It allows the target machine to continue the normal operation. Conversely, if the obstacle is removed from the detection zone while this function is carried out, the FSD turns OFF-state and it causes the machine stop. Note that enabling this function may create hazardous zones, allowing human approach against which the SL-C Series provides no protection. It is required to install additional safety protective equipment like a cover designed to prevent human approach. In order to carry out this function, the SL-C Series need not be a single transmitter/receiver pair The function can be configured to be operational for all beam axes on all SL-C Series units connected in series. (See the right diagram.) See “4-3 Fixed blanking function” (➮4-3) for more information about how to set or configure this function.

When this function is carried out, it may create a hazardous zone allowing human approach between the obstacle and the SL-C Series against which the SL-C Series provides no protection. (See the right diagram.) Be sure to install additional safety protective equipment, such as a safe guard, for this zone. When installing the SL-C Series into/ onto a machine, always follow the instructions in the SL-C Series Instruction Manual. Failure to follow this warning may result in significant harm to machine operators, including serious injury or death.

2-4 Blanking blind protection function

Chapter 2 Functions

WARNING

This function is an advanced improvement of the fixed blanking function. It can be used to eliminate the hazardous zone allowing human approach that arises when the conventional fixed blanking function is enabled. (Subject to the above warning.) A blanking blind protection unit (SL-C08SB or SL-C16SB) is required in order to enable this function. As shown in the right diagram, the blanking blind protection unit is placed on either side of the obstacle so that the SL-C Series transmitter faces the blanking blind protection unit's receiver, and the blanking blind protection unit's transmitter faces the SL-C Series receiver, with all beam axes aligned. This configuration may eliminate the hazardous zones allowing human approach that are created by the obstacle. Be sure to read “4-4 Blanking blind protection function” (➮4-4) carefully for more information about how to set and install this unit before use.

Enabling the blanking blind protection function does not necessarily remove all hazardous zones allowing human approach. Depending on the target machine, installation of the blanking blind protection unit may result in the creation of one or more hazardous zones allowing human approach. Be sure to read “4-4 Blanking blind protection function” (➮4-4) in this manual before installing or using this unit. When installing the SL-C Series into/onto a machine, always follow the instructions in the SL-C Series Instruction Manual. Failure to follow this warning may result in significant harm to machine operators, including serious injury or death.

DANGER

curtain detects the input signal from two or more muting devices (sensors, switches, etc.). The muting devices (sensors, switches, etc.) that are used to carry out the muting function as well as the method to install them must satisfy all conditions described in this instruction manual as well as the applicable requirements imposed by all laws, regulations, standards, and ordinances in effect in the country and region where the SL-R12EX is to be used. Failure to follow this warning results in significant harm to machine operators, including serious injury or death.

• The following conditions must be considered before installing muting devices (sensors, switches, etc.) to carry out the muting function.

1. The muting function of the light curtain is only permitted during the nonhazard-

ous portion of the machine cycle.

2. Muting devices must not get active and the light curtain (SL-C Series) must

not go to the muting state even if a person inadvertently approaches the light

curtain's detection zone. These are minimum requirements. Always follow the regulations in effect in the country and region where the SL-R12EX is used.

In addition, you must take note of the following information if you carry out the muting function.

• Muting of the light curtain shall be accomplished in such a manner that no

single component failure shall prevent the normal stop command and shall prevent subsequent machine cycles until the failure is corrected. (ANSI B11.19)

• Setting the muting function and muting device configuration must be restricted

to an extremely limited number of the responsible personnel.

• Any personnel other than the responsible personnel must not easily change

the position at which the muting devices are installed. When the muting devices are moved, the procedure must require the use of specialized tools and must be performed under the responsibility of the responsible personnel.

Chapter 2 Functions

The muting function supported by the SL-C Series can be classified into two types. I)A muting function where the safety functions of all beam axes, including those on SL-C Series units

connected in series, are disabled when the signals from the muting devices are ON (active).

II)A muting function (called as the programmable muting function) where the safety functions of pre-defined

beam axes are disabled when the signals from the muting devices are ON (active).

For all beam axes for which either of the functions described in I and II is enabled, the FSD keeps ON-state even when those beam axes are blocked by the detection capability. Both of the functions described in I and II above support either 2 or 4 input signals from the muting devices, comprising the 4 types of muting function described below.

Examples of 2-input muting

See “4-5 Muting function” (➮4-10) for information about how to set or configure these functions. In order to carry out this function, you must install muting devices (sensors, switches, etc.) and a muting lamp (SL-R12D is recommended). See “4-5-1 Muting devices” (➮4-10) for information about muting device requirements and “4-5-2 Muting lamps” (➮4-12) for information about muting lamp requirements.

The information presented up to this point is intended as an example of typical requirements. The satisfaction of these requirements must not be understood as being equivalent to the satisfaction of all regulations imposed on the muting function (including methods of installation and use) being used by the customer. Therefore, KEYENCE does not guarantee the validity and/or accuracy for use, installation and orientation methods of the muting devices that the customers made. Accordingly, customers intending to carry out the muting function must check the all applicable regulations in effect in the country and region where the SLR12EX is used.

Time chart explanation

(1) The muting function does not get active when both sensors A1 and A2 are OFF, or when only one of them

is ON. In other words, the light curtain (SL-C Series) keeps normal operation. (The muting function is OFF.)

(2) The muting function gets active once both sensors A1 and A2 turn ON, and then, the muting lamp turns

ON.

(3) Once either sensor A1 or A2 turns OFF, the muting function is to be inactive. Therefore, the light curtain’s

(SL-C Series) muting state is canceled. The muting lamp turns OFF, and the light curtain (SL-C Series) returns to normal operation.

Important: * The SL-C Series muting function is designed so that it cannot be active while FSD is OFF-

state. As a result, the SL-C Series does not go to the muting state when any beam axes are being blocked or when the restart interlock is enabled, even if the signals from the 2 muting devices turn ON.

* When the SL-R11 receives an E-STOP input signal, the FSD always turns to OFF-state and

the light curtain (SL-C Series) automatically goes to the restart interlock state, even if it has been in the muting state. When the E-STOP input signal is canceled and the restart input turns ON, the light curtain (SL-C Series) returns to normal operation, rather than resuming the set muting state. As a result, in order to return the light curtain (SL-C Series) to the muting state again, you must temporarily cancel the input signals from the muting devices that have been activated and resend the input signals from them to the SL-R12EX.

* The SL-C Series cannot go to the muting state after 1 muting device turns OFF, even if both

devices then turn back ON again. Both muting devices must turn OFF to get the muting function active again.

sensor A2 turns ON sequentially. At this time, the muting lamp turns ON. Further, the signal from sensor B1 turns ON, and finally, the signal from sensor B2 turns ON. As long as the light curtain (SL-C Series) receives the signals from the muting devices in this sequence, it keeps muting function.

(3) If the signal from sensor A1 turns OFF, A2 turns OFF and then B1 also turns OFF sequentially after the

signals from all the sensors turn ON, the muting function cannot keep active. Therefore, the light curtain's (SL-C Series) muting state is canceled. The muting lamp turns OFF, and the light curtain (SL-C Series) returns to normal operation.

Important: * In the event that the signals from the muting devices turn ON or OFF in a different sequence

from what is indicated in the above 2 time charts (for either the forward and reverse directions) – for example, signal input from sensor A1 is followed by signal input from sensor B1, etc. – the light curtain (SL-C Series) goes to the lockout condition, and the FSD turns OFFstate.

* The SL-C Series muting function is designed so that it cannot be active while FSD is in the

OFF-state. As a result, the SL-C Series does not go to the muting state when any beam axes are being blocked or when the restart interlock is enabled, even if the signals from the 4 muting devices turn ON in the correct sequence indicated above.

* When the SL-R11 receives an E-STOP input signal, the FSD always turns OFF-state and

the light curtain (SL-C Series) automatically goes to the restart interlock state, even if it has been in the muting state. When the E-STOP input signals are canceled and the restart input turns ON, the light curtain (SL-C Series) returns to normal operation, rather than resuming the set muting state. As a result, in order to return the light curtain (SL-C Series) to the muting state again, you must temporarily cancel the input signals from the muting devices that have been activated and resend the input signals from them to the SL-R12EX.

* In the event that a change of the signal from one of the muting devices (ON or OFF) is not

followed by a change of the signal from the next muting device in less than 5 minutes, the light curtain (SL-C Series) goes to the lockout condition, and the FSD turns OFF-state. (See the below time chart for reference.)

2-5-4 Two-input programmable muting function

Only the preset beam axes are muted if the memory bank switching input turns ON while the signals from muting devices are ON. The FSD keeps ON-state even if the muted beam axes are blocked. On the other hand, the FSD turns to the OFF-state if beam axes other than the muted ones are blocked, since those beam axes keep normal operation. The information about the preset beam axes for muting is stored in 3 memory banks, and you can switch among those banks using inputs from an external source. Although the following time chart shows only 1 bank switching input signal in order for the customer’s easy understanding of this function, actually 2 (double) signals are required for 1 bank switching input (Duplication). See “4-5-5 Bank switching input devices” (➮4-17) for more information. The following time chart shows programmable muting bank function performance when 2 sensors are used as muting devices.

(2) The muting lamp turns ON when both sensors A1 and A2 turn ON. At this time, if any one of the 3 bank

switching inputs has already been ON, the preset beam axes in the bank go to the muting state. Even if muted beam axes are blocked, the FSD keeps ON-state. If 2 or more bank switching inputs have already been ON prior to the inputs from 2 muting devices, then all preset beam axes in these banks go to the muting state.

(3) If all of the bank switching inputs turn OFF when both sensors A1 and A2 keep ON, the muting function is

canceled, and the light curtain (SL-C Series) returns to normal operation. At this time, the muting lamp does not turn OFF. (The muting lamp turns OFF when at least either sensors A1 or A2 turns OFF.)

Important:*The SL-C Series muting function is designed so that it cannot be active while FSD is in the

OFF-state. As a result, the SL-C Series does not go to the muting state when any beam axes are being blocked or when the restart interlock is enabled, even if the signals from the 2 muting devices turn ON.

* Bank switching input requires 2 (double) channels of signal input. As a result, if one of the

channels is ON while the other is OFF for 200 ms or more, the light curtain (SL-C Series) goes to the lockout condition.

* At least 1 of the bank switching inputs must be ON prior to the signal input from the second

muting device (in the example above, the input signal from sensor A2). Therefore, in order to switch among the 3 banks, you must turn the bank switching input ON when the SL-R12EX detects no signals from the muting devices, or when it only detects the signal from the first muting device (in the example above, the input signal from sensor A1).

* If additional bank switching input is made while a muted beam axis is blocked, the FSD turns

to OFF- state.

* When the SL-R11 receives an E-STOP input signal, the FSD always turns OFF-state and

* If there is no bank switching input to the SL-R12EX while the signals from the muting devices

are ON, the programmable muting bank function does not get active and the light curtain (SL-C Series) keeps normal operation. However, the muting lamp turns ON if there is signal input from the muting devices.

* The SL-C Series cannot go to the muting state after 1 muting device turns OFF, even if both

devices then turn back ON again. Both muting devices must turn OFF to get muting function active again.

2-5-5 Four-input programmable muting function

Only preset beam axes can be in a muting state if the memory bank switching input turns ON while the signals from the muting devices are ON. The FSD keeps ON-state even if the muted beam axes are blocked. On the other hand, the FSD turns OFF-state if beam axes other than the muted ones are blocked, since those beam axes keep normal operation. The information about the preset beam axes for muting is stored in 3 memory banks, and you can switch among these banks using inputs from the external sources. Although the following time chart shows only 1 bank switching input signal in order for customer’s easy understanding for this function, actually 2 (double) signals are required for 1 bank switching input (Duplication). See “4-5-5 Bank switching input devices” (➮4-

17) for more information. The following time chart shows programmable muting bank function performance when 4 sensors are used as muting devices.

Time chart explanation

(1) The muting function does not get active when both sensors A1 and A2 are OFF, or when only one of them

is ON. In other words, the light curtain (SL-C Series) keeps normal operation. (The muting function is OFF.)

(2) The muting function is enabled once the signal from sensor A1 turns ON at first and the signal from

sensor A2 turns ON sequentially. At this time, the muting lamp turns ON. If any one of the 3 bank switching inputs has already been ON, the preset beam axes in the bank go to the muting state. Even if muted beam axes are blocked, the FSD keeps ON-state. If 2 or more bank switching inputs have already been ON prior to the inputs from 2 muting devices, the all preset beam axes in these banks go to the muting state.

(3) The signal from sensor B1 turns ON, and then, the signal from sensor B2 should turn ON. As long as the

SL-R12EX detects the signals from the muting devices in this sequence, it keeps the muting function as in (2) above.

(4) Even if the signal from sensor A1 turns OFF and then A2 also turns OFF sequentially after the signals

from all the sensors turn ON, it keeps the muting function as in (2) above as long as the SL-R12EX detects the signals from the muting devices in this sequence and the signals from sensors B1 and B2 still keep ON. Even if muted beam axes are blocked, the FSD keeps ON-state.

(5) When the signal from sensor B1 turns OFF, the muting function is canceled, and the light curtain (SL-C

Series) returns to normal operation. At this time, the muting lamp turns OFF. Alternatively, if all bank switching inputs turn OFF, even as the signal from sensor B1 keeps ON, the muting function is canceled, and the light curtain (SL-C Series) returns to normal operation. At this time, the muting lamp does not turn OFF. (The muting lamp turns OFF when sensor B1 turns OFF in correct sequence.)

(2) The muting function is enabled once the signal from sensor B2 turns ON at first and the signal from

Chapter 2 Functions

Important: * In the event that the signals from the muting devices turn ON or OFF in a different sequence

from what is indicated in the previous 2 time charts (for either the forward and reverse directions) – the light curtain (SL-C Series) goes to the lockout condition, and the FSD turns OFF-state. For example, a signal input from sensor A1 is followed by a signal input from sensor B1, etc.

* One of the bank switching inputs must be ON prior to the signal input from the second

muting device. (For the forward direction sequence, input from sensor A2; for the reverse direction sequence, input from sensor B1). Therefore, in order to switch among the 3 banks, you must switch the bank switching input when the SL-R12EX receives no signals from the muting devices, or when it only receives the signal from the first muting device. (For the forward direction sequence, input from sensor A1; for the reverse direction sequence, input from sensor B2).

* The SL-C Series muting function is designed so that it cannot be active while FSD is OFF-

state. As a result, the SL-C Series does not go to the muting state when any beam axes are being blocked or when the restart interlock is enabled, even if the signals from the 4 muting devices turn ON in the correct sequence indicated above.

* If there is no bank switching input to the SL-R12EX while the signals from the muting devices

* If additional bank switching input is made while a muted beam axis is blocked, the FSD turns

OFF-state.

* Bank switching input requires 2 (double) channels of signal input. As a result, if 1 of the

channels is ON while the other is OFF, the light curtain (SL-C Series) goes to the lockout condition.

* When the SL-R11 receives an E-STOP input signal, the FSD always turns OFF-state and

the light curtain (SL-C Series) automatically goes to the restart interlock state, even if it has been in muting state. When the E-STOP input signal is canceled and the restart input turns ON, the light curtain (SL-C Series) returns to normal operation, rather than resuming the set muting state. As a result, in order to return the light curtain (SL-C Series) to the muting state again, you must temporarily cancel the signal input from the muting devices that have been activated and resend the input signals from them to SL-R12EX.

tion connections, and the total number of beam axes on the BBP units used with the Main and Sub 1 units is 24 or higher;

2. When there are 4 sets (Main, Sub 1, Sub 2, and Sub 3) of light interference

prevention connections, and the total number of beam axes on the BBP units

used with the Main, Sub 1, and Sub 2 units is 16 or higher. If your system meets the conditions described in either (1) or (2) above, you should power on devices in the following order: Main, Sub 1, Sub 2, Sub 3. Wait at least 1 second after turning each device on.

Installing the blanking blind protection (BBP) unit and the SL-C Series

Install the BBP unit and SL-C Series properly, aligning them with the obstacle on the target machine. The following table and diagram provide the information required to properly install the BBP unit. This information is also provided to help you determine whether your particular BBP unit installation will result in a new hazardous zone allowing human approach. Be sure to properly install, if necessary, any additional safety protective equipment as well as the BBP unit according to the following table and diagram.

4-5 Muting function

4-5-1 Muting devices

(1) Requirements for muting devices

The sensors, switches, and other equipment used as muting devices are subject to the requirements such as the following. Muting devices must satisfy these requirements at least when enabling the muting function.

• Muting device must have NO (normal open) contact output, PNP or NPN output.

• No single device with two or more outputs shall be used instead of two or more muting device.

Muting device must not be set to make use of multiple output functions. (Only 1 output can be used per device; output sources must be separated.)

• Muting devices must not be set to make use of ON/OFF delay functions, or any other functions that

modify output timing or pattern.

• Must satisfy SL-R12EX input specifications. See “1-2 Specifications” (➮1-3).

DANGER

(2) The muting device input indicator

The muting device input indicator lights when the SL-R12EX detects the input from the muting device.

(3) The wiring of 2 muting devices

Wiring for the muting devices can be made only while the power to the SL-R12EX is OFF. The following requirements must be met when making wiring connections to the SL-R12EX terminal block. Tightening torque: 0.4 N•m Wire rating: AWG # 28 to 14 (Stranded only, Copper only, min. 60° C) Cable stripping dimension:

• The above requirements of muting devices are a partial and representative example of applicable requirements, not completely all requirements. Therefore, be sure to confirm the special safety-related requirements such as national or regional laws, rules, regulations, standards, and ordinances prior to use, installation or orientation of muting devices. For more information, contact the organization that has jurisdiction over national or regional occupational health and safety. The proper selection, usage, installation and orientation of the muting devices are the responsibility of the employer and installer.

•A simple cam-operated limit switch wired in parallel with the device’s output is inadequate, as its failure can remain undetected. (ANSI B11.19)

4-5-2 Muting lamps

(1) Requirements for muting lamp

The muting lamp is the indicator showing that the SL-C Series is in a muting state. The following requirements must be met for the lamps used as muting lamps. The lamps that satisfy these requirements or SL-R12D must be always used when enabling the muting function.

• Illuminated area must be at least 1 cm2.

• Luminance must be at least 200 cd/m2.

• Rated voltage must be 24 V DC, and current consumption must be between 15 and 300 mA. (If 2 or more muting lamps are used, they must be connected in series to the LAMP terminal on the SL-R12EX. Since this LAMP terminal supplies 24 V DC, if you use N number of muting lamps, use lamps that have a rated voltage of 24/N.)

• It must be an incandescent lamp.

CAUTION

WARNING

• When the rating of the muting lamp in use is 24V 2W or 30V 2W, control the equipment so that the muting lamp off time (time when the muting function is off) is at least one second long. Failure to do so will cause the SL-C series to enter lockout condition.

• Be sure to use an incandescent lamp as the muting lamp. When using a lamp other than an incandescent lamp as the muting lamp, SL-R12EX cannot detect failure on the lamp. If failure occurs on the lamp, the SL-C series will not enter lockout condition. The lamp does not light up even if SL-C series is in mute state and the operator is placed at risk. Therefore make sure to not use a lamp other than incandescent lamp.

4-12

Page 51

Chapter 4 Wiring and setting

< Cautions and Warnings when Verifying Operations >

When installing a lamp other than an incandescent lamp (for instance, an LED lamp) or a resistance load to verify whether the functions of the SL-C series are functioning correctly, be sure to take the following precautions.

• When actual consumption current is 20 mA or less, check that the muting lamp off time (time when the muting function is off) is at least one second long. Failure to do so will cause the SL-C series to enter lockout condition.

•A resistance load or the lamp except for incandescent lamp can be used for a short period of time to verify the correct operations of the muting function, but it should not be used as the muting lamp. After verifying operations, make sure to remove the lamp other than incandescent bulb or the resistance load and use a lamp recognized in this instruction manual as a muting lamp. Failure to do so may result in significant harm to machine operators, including serious injury or death.

WARNING

CAUTION

• The muting lamp or the SL-R12D must be installed prior to carrying out the muting function on the SL-C Series. The muting lamp or the SL-R12D must be installed at the location where they can always be clearly and easily visible for the machine operators or the responsible personnel in case of normal machine operation, setting or alignment for muting or maintenance, etc.

Failure to follow this warning may result in significant harm to machine operators, including serious injury or death.

• The LAMP terminal on the SL-R12EX is the dedicated terminal intended for muting lamps. Do not use it to supply power to other devices.

Important: The SL-R12EX is so designed that it always monitors the connection to the muting lamp. As a

result, if the SL-R12D or the other muting lamps are not connected to the SL-R12EX (including the case of breaks along lamp cables and disconnection of cables), the light curtain (SL-C Series) goes to the lockout condition, and the FSD turns OFF-state.

4-5-5 Bank switching input devices

(1) Bank switching input

The SL-R12EX is designed so that it requires 2 (double) signal inputs to serve as a single bank switching input. Therefore, 2 signals of input to the SL-R12EX are necessary for each bank switching input.

(2) Generating bank switching inputs

Up to three memory banks can be configured. Input the bank switching input signal corresponding to the memory bank you want to use on the SL-R12EX.

When input 1 turns ON, bank 1 is enabled and the input 1 indicator turns ON. When input 2 turns ON, bank 2 is enabled and the input 2 indicator turns ON. When input 3 turns ON, bank 3 is enabled and the input 3 indicator turns ON.

(3) Wiring method

Wiring for the muting devices can be made only while the power to the SL-R12EX turns OFF. The following requirements must be met when making wiring connections to the SL-R12EX terminal block. Tightening torque: 0.4 N•m Wire rating: AWG # 28 to 14 (Stranded only, Copper only, min. 60° C) Cable stripping dimension

Method for switching the BEAM indicator The 8 “BEAM” indicators can light in the order from “Beam 1-16” to “Beam 113-128” by pressing the beam switching button. Therefore, you can monitor the information through the “CLEAR/BLOCKED” indicators, which is related to the beam axes range corresponding to the lighting indicator.

With small numbers of beam axes, only indicators up to that number will light.

Example With 40 beam axes, pressing the beam switching button will cause the indicators to cycle in the following order: 1 to 16 → 17 to 32 → 33 to 48 → 1 to 16.

5 Checklist

5-1 List of Pre-use check Items

After the SL-C series, the SL-R11 and the SL-R12EX are installed, the responsible personnel must use the following checklist to check the operation. The following checklist contains the minimum necessary items for using the SL-R12EX. The required check items will differ depending on the laws, ordinances, regulation and other requirements of the country and region where the SL-R12EX is being used, as well as with the machine onto which they are installed. Therefore, KEYENCE strongly recommends that the responsible personnel add any required check items to this checklist. This checklist is only to be used for the SL-R12EX, so refer to the SL-C Series and SL-R11 instruction manuals to create a checklist based on using the SL-R12EX in combination with the SL-C Series and the SLR11.

5-1-1 Checking the SL-R12EX installation conditions

The SL-R12EX is installed in an appropriate enclosure with at least IP54 rating (in a control box,

❏

etc.).

The muting lamp or the SL-R12D is installed at the location where they can always be clearly and

❏

easily visible for the machine operators or the responsible personnel in cased of normal machine operation, setting or alignment for muting or maintenance, etc.

If it is necessary to install 2 or more muting lamps, the muting lamps must be installed so that they

❏

are connected in series to the LAMP terminal on the SL-R12EX terminal block.

Muting devices are installed such that the muting function cannot be active when the hazard of the

❏

machine on which the light curtain is installed exists on the machine side of the light curtain (inside the hazardous zone)

Muting devices are installed such that they cannot get active and the light curtain (SL-C Series)

❏

cannot go to a muting state even if a person inadvertently approaches the light curtain's detection zone.

If the BBP unit creates a new hazardous zone allowing human approach, additional safety

❏

protective equipment such as a safe guard are installed for that zone.

5-1-2 Checking wiring

For the power supply to the SL-R12EX, only a dedicated power supply must be used to supply

❏

power to the SL-C Series light curtain system, including the SL-R11 and the SL-R12EX. No other device can be supplied from the same power supply.

The SL-U2 power supply recommended by Keyence or a 24 V DC power supply that satisfies the

❏

requirements defined in this instruction manual is used as the power supply for the SL-R12EX. (➮ See 1-4 Power supply requirements on page 1-6).

The BBP transmitter cable (gray) is correctly connected to the BBP transmitter cable connector,

❏

and the BBP receiver cable (black) is also correctly connected to the BBP receiver cable connector.

6 Troubleshooting

Chapter 6 Troubleshooting

When the SL-C Series, the SL-R11, or the SL-R12EX experiences an error, it is possible to determine the cause of the error by referring to the blinking MODE STATUS indicators on the SL-R12EX. The light curtain can be returned to the normal operation by turning the SL-R12EX OFF and then back ON after the cause of the error has been removed.

Blinking

indicator(s)

1 SL-C Series error

2 Communication error

Description Causes and solutions

The SL-C Series has some error. See “5 Troubleshooting” (➮ 5-1) in the SL-C Series instruction manual.

• Check for incorrect wiring, broken wiring, or loose connections for the light interference prevention cables.

• Use specified cables as described in “4-4 About the Light Interference Prevention Connection” (➮ 4-9) in the SL-R11 instruction manual when wiring the system or extending its wiring.

• If the system is wired so that the light interference prevention cables are protruding from their shielded cables, make the protruding lengths as short as possible.

• If the light interference prevention cables are connected using a terminal block, connect them directly without going through the terminal block.

• If light interference prevention connections have been made, the main/sub switch is set so that there are multiple main units configured. Always configure the system so that there is only 1 main unit, as described in section “4-3-4 Connecting to Main/Sub Select Input Te r minal” (➮ 4-7) in the SL-R11 instruction manual.

• If the SL-C unit has been configured as a sub unit with the light interference prevention connection, the power has been cut to the SL-C unit that is configured for either the main unit or the sub unit that is connected closer to the main unit. Be careful not to cut power to only some of the connected SL-C units.
