2. General Precautions

•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-C if it is used in a manner that
differs from the SL-C specifications contained in this instruction manual or if the SL-C is modified.

• When using the SL-C 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-C 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-C 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-C 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-C. “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-C and must understand and follow the
safety regulations for the country or region in which they are using the SL-C.

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

• The SL-C 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-C after conducting a sufficient risk
assessment for the target machine.

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

iii

3. Warning

■ Operators

• In order for the SL-C 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-C.

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

region in which the SL-C 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-C.

• The SL-C 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-C in the presence of substances, such as heavy smoke, particulate matter, or corro-

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

• Install the SL-C in such a way so that no direct or indirect light from inverter-type fluorescent lights

(rapid-start type lights, high-frequency operation type lights, etc.) shine on the device.

■ Target machine

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

Japanese Industrial Safety and Health Law. The SL-C, 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-C is to be installed must be susceptible to an emergency stop at all

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

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

• Do not use the SL-C 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-C 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.

iv

ENGLISH

■ Installation

• The SL-C must be installed only after securing the minimum safety distance between the SL-C and the

hazardous zone or hazard as established by the applicable regulations of the country or region in which
the SL-C is being used.

• Choose locations for the installation of SL-C transmitters and receivers so that they are not subject to

the effects of light reflected from glossy surfaces in the area.

• Use the same models (same beam axis) for transmitter/receiver pairs.

• The SL-C must be installed in such a way that machine operators cannot reach the hazardous zones or

hazards of the machine without passing through the SL-C's detection zone. Strictly avoid installations
which allow machine operators to access the area between the SL-C and the machine, or where ma­chine operators can approach the machine's hazardous zones, without passing through the SL-C's
detection zone.

• Always perform tests after installing the SL-C in accordance with the test procedures established in this

instruction manual, verifying that the test pieces are detected in all of the detection zones.

• When the Intelligent Extension Unit (SL-R12EX) is used to enable the fixed blanking function, additional

safety measures must be implemented for the zone in which that function is enabled so that it is impos­sible to reach the hazardous zone or hazards of the machine by passing through that zone. This func­tion cannot be used with SL-C**L having the detection capability of 45 mm diameter.

• When the Intelligent Extension Unit (SL-R12EX) is used to enable the floating blanking function, the

minimum safety distance will be affected due to the fact that the function has a negative effect on the
detection capability. Therefore, in such cases, calculate the minimum safety distance using the new
value for detection capability with the floating blanking function enabled and apply the result for the SL­C installation. This function cannot be used with SL-C**L having the detection capability of 45 mm
diameter.

• When the Intelligent Extension Unit (SL-R12EX) is used to enable the floating blanking function, confirm

that the actual number of beam axes with which the floating blanking function is active matches the
number of beam axes specified in the floating blanking function setting. This function cannot be used
with SL-C**L having the detection capability of 45 mm diameter.

• When the Blanking Blind Protection Unit (SL-C08SB/SL-C16SB) is used to install the SL-C, a test must

be carried out according to the procedures described in this instruction manual to confirm that the test
piece can be detected in all detection zones including the detection zone that can be detected by the
Blanking Blind Protection Unit. This function cannot be used with SL-C**L having the detection capabil­ity of 45 mm diameter.

• Securely tighten mounting brackets and cord (cable) connectors used in the installation of the SL-C in

accordance with the torque values established in this instruction manual.

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-C 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-C in the same duct as high-voltage
electrical or power lines or in parallel with such lines.

• Do not extend transmitter and receiver cables over a maximum distance of 30 meters (98.43 ft.).

• Install the mechanism used to reset the interlock (switches, etc.) in a position from which the condition of
the entire hazardous zone can be checked. Do not install the reset mechanism in a position where it can
be operated within the hazardous zone.

• The control outputs (OSSD for SL-C Series or FSD for SL-R11) of the two systems provided in the SL-C
must both be used to build a safety system. Building a safety system with just one of these systems
cannot stop the machine due to a control output malfunction and can result in a serious accident, includ­ing serious injury or death to the machine operator.

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-C, and before the machine start-up.

• If the SL-C 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 the SL-C.

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

1. Lockout indicator
If the SL-C control circuit detects an error, the SL-C goes to lockout condition and the status indicator
turns orange. At the same time, the OSSD output (or FSD output when the SL-R11 is connected to the
SL-C) is turned off and the machine stops.

2. Bar LEDs
Each transmitter and receiver has an 8-segment LED indicator that shows the SL-C operation status.
When the paths of all beam axes are clear of any obstruction in the normal state, all LEDs turn green.
When there is some blockage of the beam axes, some of the eight LEDs will turn red to indicate the
percentage of the total beam axes whose light beams are being received.
When receiver cannot get any light from transmitter in spite of no obstruction, the red LED at the bottom
flashes.

ENGLISH

English

3. Output status indicator
This indicates the OSSD output status (or the FSD output status if the SL-R11 is connected to the SL-C
Series). When the OSSD (or FSD) output is turned ON, the indicator lights green. When the OSSD (or
FSD) output is turned OFF, the indicator turns red.
Therefore, if the output status indicator is red, the OSSD (or FSD) output is turned OFF and the machine
has been stopped regardless of the functions being used.

4. Function indicator
The function indicator turns orange if each function supported by the SL-R12EX has been enabled. For
details, see the Instruction Manual for the SL-R12EX.

1-5-3 Test Input

The test input stops light beam transmission from the transmitter using an external input.
The test input is used to see if the machine connected to the SL-C can stop within the prescribed time when
the OSSD (FSD when the SL-R11 is connected to the SL-C) turns off.
For example, when test input is triggered when the SL-C is in the normal state (when OSSD or FSD output is
on when all beam axes are clear of any obstruction), the OSSD or FSD is turned off and only one bar LED of
the SL-C flashes red. (Exception is when the fixed blanking function is used.)
The test input cannot be used when the SL-R12EX is used and the Programmable Muting Bank function is
enabled. Therefore, the Programmable Muting Bank function must be canceled to enable the test input.

Chapter 1 Overview and Specifications

1-5-4 NPN and PNP Outputs

The SL-C has two types of OSSD outputs: PNP output and NPN output. KEYENCE has a PNP output cable
and a NPN output cable for use as dedicated OSSD output cables, The OSSD output type can be switched
by selecting one of these cables.
These cables are identified by the color of the connector connected to the SL-C and by the tag attached to
the cable as follows.

Cable Type Connector color

PNP output cable Black
NPN output cable Grey

1-5-5 Series Connection

2 or more sets of SL-C units can be connected by using a pair of dedicated series connection cables to form
a light curtain with a single set of output logic (see figure below).
In this instruction manual, the unit that is directly connected to the power supply unit and that supplies power
to the sensor units connected in series is called the “Unit 1,” and the next unit that is connected to the Unit 1
using a dedicated series connection cable are called “Unit 2.” Further, when used in serial connections the
device connected after “Unit 2” is “Unit 3”, and the next device is “Unit 4”.
For details regarding the connection method,

refer to “3-5 Series Connection” (➮ page 3-4).

1-5-6 Light Interference Prevention Connection

As shown in the figures below, using the light interference prevention function allows the parallel connection
of 2 or more sets of SL-C units and prevents light interference in the respective SL-C units. This connection
method is called a light interference prevention connection. (See the figure below.)
In this instruction manual, the unit that is connected parallel to the SL-C via a light interference prevention
cable and that transmits a signal for light interference prevention is called the “main unit”. The units that
receive the light interference prevention signal from the main unit and operate in accordance with this signal
are called “sub unit.”
When making a light interference prevention connection, one pair of SL-C Series units must be set as the
main unit, and the other as the sub unit.
For details regarding the connection method,

WARNING

Chapter 2 Installation and Assembly

Mounting position of transmitter and receiver:

Correct position

• The hazardous zone or hazards within the machine are accessible only through the SL-C detection

zone.

• While the machine is running, the machine operator's body always stays on the opposite side of the

hazardous zone or hazard.

Incorrect installation

• The machine operator can access the hazardous zone or hazards without passing through the SL-C

detection zone.

• The machine operator’s body can enter between the SL-C detection zone and hazardous zone or

hazard while the machine is running.

ENGLISH

English

If the machine operators are not protected from hazards by the SL-C in the entire
hazardous zone, always add a safety protective equipment such as a safety guard
to the portion of the hazardous zone that is not covered by the SL-C. Also, install
the SL-C so that the machine operators cannot access the hazardous zone or
hazards without passing through the SL-C’s detection zone or protection zone. In
other words, do not install the SL-C in a layout that allows machine operators to
enter between the SL-C and the machine's hazardous zone or hazards without
being detected by SL-C or access the machine's hazardous zone or hazards by
bypassing the SL-C's detection zone. If these warnings are violated, it may result
in serious harm, such as an injury or death of the machine operator.

Install the SL-C after calculating and verifying the necessary safety distances.

• Minimum safety distance
The minimum safety distance refers to the minimum distance that the light curtain must be separated from
the hazardous zone or hazard in order to stop the machine before people or objects can reach the
hazardous zone or hazard. The centerline at the SL-C’s beam axis surface is used as the origin when
calculating the minimum safety distance.

Chapter 2 Installation and Assembly

2-2-1 ISO13855

<Example 1: Safety distance calculation according to ISO13855:2010 (in a case where the detection

zone is perpendicular to the direction of approach)>

Formula: S = K x T + C..... (A)

S: Safety distance (mm)
K: Approaching speed of the body or the parts of body into detection zone (mm/s)
T: Overall response time (s) (T= t1 + t2)
t1: SL-C Series maximum response time (15 ms)
t2: Maximum time required by the machine to stop after receiving the signal from protective

equipment (SL-C)

C: Additional distance (mm) calculated from the SL-C detection capability.

[Calculation example for a detection capability of 40 mm (1.57") or less]

The safety distance is calculated using Formula (A) and the parameters established in
ISO13855 with K = 2,000 mm/s and C = 8 (d - 14 mm (0.55")). C is a value determined from
the d: SL-C Series detection capability diameter (mm) and must be equal or greater than 0.
This is the example when the SL-C**H is used.

S= 2,000 mm/s x (t1 + t2) + 8 (d - 14 mm (0.55"))..... (B)

When t1 = 15 ms, t2 = 50 ms, d = 25 mm (0.98"):
S= 2,000 mm/s x (0.015 s + 0.05 s) + 8 (25 mm (0.98") - 14 mm (0.55"))

= 218 mm (8.58")

* The safety distance calculated using Formula (B) above must be 100 mm (3.94") or

more and 500 mm (19.69") or less. When the calculated safety distance is less than
100 mm (3.94"), use a safety distance of S = 100 mm (3.94"). Accordingly, the
safety distance acquired from Formula (B) above is S = 218 mm (8.58").
If on the other hand the safety distance calculated using Formula (B) above
exceeds 500 mm (19.69"), set K = 1,600 mm/s and calculate the safety distance

again using Formula (A).

S= 1,600 mm/s x (t1 + t2) + 8 (d - 14 mm (0.55"))..... (C)

When t1 = 15 ms, t2 = 300 ms, d = 25 mm (0.98"):
S= 1,600 mm/s x (0.015 s + 0.3 s) + 8 (25 mm (0.98") - 14 mm (0.55"))

= 592 mm (23.31")

* The safety distance calculated using Formula C above must be 500 mm (19.69") or

more. When the calculated safety distance is less than 500 mm (19.69"), use a

safety distance of S = 500 mm (19.69"). Accordingly, the safety distance acquired

from Formula (C) above is S = 592 mm (23.31").
* When the SL-C is being used in a non-industrial application, the minimum safety

distance is calculated by adding 75 mm (2.95") to the result from Formula (B).

Formula (C) cannot be used in this situation. Accordingly, when the SL-C is used in

a non-industrial application, a safety distance of S = 218 mm (8.58") + 75 mm

(2.95") = 293 mm (11.54") is required.

ENGLISH

English

[Calculation example for a detection capability of 40 mm (1.57") or more and 70 mm (2.76") or
less]

When the SL-C**L is used or when the SL-C series other than SL-C**L is used with the
Intelligent Extension Unit (SL-R12EX) to activate the floating blanking function, the detection
capability will exceed 40 mm (1.57"). This section provides an example of the calculation
when using SL-C**L.

The safety distance is calculated using Formula (A) and the parameters established in
ISO13855 with K = 1,600 mm/s and C = 850 mm (33.46").

S= 1,600 mm/s x (t1 + t2) + 850 mm (33.46")
When t1 = 15 ms, t2 = 50 ms,
S= 1,600 mm/s x (0.015 s + 0.05 s) + 850 mm (33.46")

= 954 mm (37.56")

Accordingly, the safety distance for this application is S = 954 mm (37.56").

<Example 2: Safety distance calculation according to ANSI B11.19-2010 (in a case where the

detection zone is perpendicular to the direction of approach)>

Equation: Ds=K x T + Dpf

Ds: Safety Distance (inch)
K: The maximum speed that an individual can approach the hazard
T: The total time that it takes for the hazardous motion to stop, or for the hazardous portion

of the machine cycle to be completed. This value includes portions of time that vary by
machine type and by the safeguarding device applied.

Dpf: The distance (depth) penetration factor. This value varies depending on the SL-C detec-

tion capability. Dpf=3.4(S-0.275)inch. See the below figure.

Penetration factor, Dpf, for presence-sensing devices used in a vertical

application with object sensitivity less than 64 mm (2.5 inches)

2

* One of the accepted values for K is the hand speed constant (It is usually considered as

the horizontal motion of the hand and arm while seated). Its common value is 1.6m/s
(63inch/s) although other values (typically greater) are also used. The hand speed con­stant does not include other body movements, which can affect the actual approach
speed. Consideration of the above factors should be included when determining the
speed constant for a given application. OSHA 1910.217(c) provides K = 63 inch/s (= 1,600

mm/s) as a recommended value.
For more detail information, especially calculation for the value of “T”, see ANSI B11.19-2010

2-3 Mounting Procedure

2-3-1 Connecting Cable Installation

This section explains how to install the connecting cables to the SL-C.

• Connect the transmitter cable (having the grey shield) to the transmitter cable connecter as shown below.
Similarly, connect the receiver cable (having the Black cable shield) to the receiver cable connector.
(Recommended tightening torque is 0.5N•m) Use two screws to secure the cable connector.
When bending the cable, the radius of the bend must be 5mm (0.2") or more.

2-3-2 Fixing the Mounting Brackets

The installation holes for screws on mounting brackets for the SL-C are slot­shaped so that they are larger than the actual screw size with which they are
intended to be used. This additional space can be used to adjust the position in
which the device is installed. For this reason, the proper installation of the device
should be verified according to the procedure outlined in “4-1 Maintenance (➮ page
4-3)” in the event that maintenance requires the removal of the device from its
target equipment or the adjustment of its installation position after its initial installa­tion onto that target equipment. Failure to follow these installation procedures may
result in significant harm to machine operators, including serious injury or death.

This section explains how to attach the SL-C mounting brackets.

2-3-4 Installation Distance from Glossy Surfaces

• Installation Distance Not Affected by Glossy Surface

If the ambient light is reflected by glossy surfaces around the SL-C, the SL-C Series may not operate
correctly and it may not detect an object approaching the SL-C detection zone.

To avoid such a problem, check the following during an SL-C installation.

2

* Although the SL-C has an effective aperture angle of ±2.5 degrees, use the value of ±3.0 degrees

taking into account any beam axis deviations and other errors that may occur during an installation.
The minimum distance (Y) from the detection zone to the reflection surface can be read from the above
graph or determined using the following formula below. The value Y of this formula is determined as­suming the worst case scenario that beam axis misalignments occur both on the transmitter and the
receiver.

Calculating the minimum distance Y

If X (operating distance (mm)) > 3000 (118.11"):

Y=X (tan3 °) =0.052X

If X (operating distance (mm)) ≤ 3000 (118.11"):

Y=157 (6.18")

The SL-C must be installed in a position not affected by reflections from glossy
surfaces (Light Interference). If there is any glossy surface near the SL-C, cover
such surfaces with a black sheet or apply a black matle finish. Make sure that no
reflected light reaches the SL-C. Otherwise, the SL-C may malfunction due to the
light reflected by the glossy surface and serious harm, such as an injury or death of
a machine operator, may result.

3-1 Wiring Methods

This section explains how to wire the SL-C Series components.

Chapter 3 Wiring

WARNING

• When using the PNP output, do not short-circuit the control output cable (OSSD)

to +24V. Otherwise, the output will always remain ON, which is dangerous.

• When using the NPN output, do not short-circuit the control output cable (OSSD)

to 0V. Otherwise, the output will always remain ON, which is dangerous.

• When using the PNP output, connect the load between the control output

(OSSD) and 0V. If it is erroneously connected between the control output
(OSSD) and +24V, the OSSD does not operate normally and is turned ON when
the beams are blocked. This is very dangerous.

• When using the NPN output, connect the load between the control ouput (OSSD)

and +24V. If it is erroneously connected between the control output (OSSD) and
0V, the OSSD does not operate normally and turns ON when the beams are
blocked. This is very dangerous.

• Always build a safety system using both of the control output systems provided in

the SL-C (OSSDs for SL-C Series and for SL-R11E, or FSDs for SL-R11). If a
safety system is built using a single control system only, it is not possible to stop
the machine when the control output system fails. This may result in serious
harm, such as serious injury or death of the machine operator.

• Regardless of whether the cables are PNP or NPN type, you must fulfill the

requirements of Clause 9.4.3 in IEC60204-1: 2005 for protection against
maloperation due to earth fault.

3-2 Power Requirements

1. Power Supply Units that can be used for the SL-C

length exceeds the limit, the SL-C may not operate normally and a serious accident, such as
an injury or death of a machine operator, may result. In addition, when bent or flexed, these
cables should be allowed a minimum bend radius of 5 mm (0.2").

3-5 Series Connection

2 or more sets of the SL-C can be connected by using a pair of dedicated series connection cables to form a light
curtain with a single set of output logic.
If any beam axis of any series-connected SL-C unit is blocked, the OSSD output (or FSD output) is turned OFF and
the machine can be stopped.
This function is valid only when the number of SL-C connected in series is 4 pairs or less and the total number of SL­C beam axes is 192 or less. The response time of the SL-C Series is not affected by the series connection.

Use the series connection cables.

• SL-S0: Cable length 0.08 m (3.15")

• SL-S1: Cable length 0.15 m (5.91")

• SL-S2: Cable length 0.5 m (1.64 ft.)

• SL-S3: Cable length 3 m (9.84 ft.)

• SL-S4: Cable length 1 m (3.28 ft.)

• SL-S10: Cable length 10 m (32.79 ft.)

When installing a series connecStion cable, remove the top edge connector cover, and then install the cable.

WARNING

Use only the series connection cables provided by KEYENCE (

page 1-3) for special cable types and relevant information

not operate normally and serious harm, such as an injury or death of the machine
operator, may result. Synchronization cables must be shielded cables. Failure to use
shielded cable may result in significant harm the machine operator, including serious
injury or death. When connecting the SL-C units in a series configuration by using the
SL-S10, limit the number of the SL-S10 units to two or less, and the total length of the
cables including the series-connection cables to 43 m (141.08 ft.) or less.

Connection for Light Interference Prevention (Parallel Connection)

As shown in the figure below, using the light interference prevention function allows the parallel con­nection of 2 or more sets of SL-C units and prevents light interference in the respective SL-C units.
This connection method is called a light interference prevention connection. (See the figure below.)
In this case, each of the parallel-connected SL-C units operates independently. Thus, when the beam
axis of one SL-C unit is blocked, its OSSD output (or FSD output) is turned OFF while the OSSD
outputs (or FSD output) of other SL-C units connected in parallel remain ON.

To use the light interference prevention connection, first set a pair of SL-C units as the main units.
Also, connect the other SL-C units with the main units via light interference prevention wires and set
them as sub units.
Connect the main unit to the sub units using light interference prevention wires as shown below. The
connection sequence is as follows.

• Connect the main unit receiver's interference prevention cable (output/+) (gray) to the interference

prevention cable (input/+) (gray) sub unit transmitter that will be connected in parallel.

•Next, connect the interference prevention cable (output/-) (gray/black) of the main unit receiver to the

interference prevention cable (input/-) (gray/black) of the sub unit transmitter.

• Leave disconnected the interference prevention cable (input/+) (gray) and the interference preven-

tion cable (input/) (gray/black) for the unused main unit transmitters as well as the interference
prevention cable (output/+) (gray) and the interference prevention cable (output/-) (gray/black) for

the sub unit receiver after properly insulating them.
To enable the light interference prevention function, the power to the main units and sub units must be
turned ON. (If the power supply of a sub unit is turned OFF during the operation, said unit and its non­priority sub unit will go into a lockout condition and their operations will be stopped.)

Chapter 3 Wiring

•Waveforms of control outputs

The SL-C performs a self-diagnosis test for the output circuit when all beam axes are clear of any
obstruction and the OSSD is in an ON-state. This self-diagnosis function periodically turns OFF the
OSSD output.
The OSSD output is monitored by the SL-C and, if the OFF state signal is fed back, the SL-C deter­mines that the output circuit operates normally.
On the other hand, if the OFF state signal is not fed back, the SL-C determines that an error has oc­curred in the output circuit or wiring and goes into a lockout condition.
For this reason, all the other devices used to receive the SL-C OSSD output must be of the type that
does not respond to this periodic off state.

3-9 Beam Axis Adjustment

This section explains how to adjust the beam axes after power-on.

Adjustment procedures:

To assure accurate beam axis adjustment, make sure that all obstacles in the SL-C detection zone are
cleared and the transmitter and receiver surfaces are clean.

1. Adjust the beam axis of both the transmitter and the receiver.
(a) Place the transmitter and receiver facing each other, and adjust their angles so that all bar LEDs

turn green.

(b) If a bar LED flashes green, the amount of receiving light is insufficient. Re-adjust the angle of

the transmitter and/or receiver until the bar LED turns green.

2. Find the range in which the bar LED remains green and fix the angle to the center of the range.

3. After completing the beam axis adjustment, re-tighten the angle holding screws on the SL-C mount­ing brackets.

- The recommended tightening torque for standard mounting brackets is 0.7 N•m.

- The recommended tightening torque for E-to-E mounting brackets is 1.2 N•m. (When the protect

bar is in use, 0.9 N•m)

ENGLISH

English

If all bar LEDs do not turn on green after completing the receiver angle adjustment, check if the
transmitter and receiver are mounted parallel to each other, the transmitter and receiver are
mounted at same level to each other, or the transmitter and receiver are mounted on the same
plane.
