2-3 Protection Area

2-3-1 Sensing Area

Be sure to install protection structure around the machine so that the operator

●

must pass through the sensing area of this device to reach the dangerous parts
of the machine. Furthermore, ensure that some part of the operator’s body al­ways remains in the sensing area when operation is done with the dangerous
parts of the machine. Failure to do so can result in death or serious injury.

Do not use any reection type or recursive reection type arrangement.

●

Furthermore, facing several receivers towards one emitter, or vice versa, could

●

produce a non-sensing area or cause mutual interference, which may result in
death or serious injury.

The sensing area is the zone formed by the sensing height of the device and the sensing range
between the emitter and the receiver. The sensing height is determined by the number of beam
channels. Furthermore, the sensing range can be 0.3 to 9m for SF4B-H□G<V2> (12 to 64 beam
channels) and SF4B-A□G<V2> (6 to 32 beam channels), 0.3 to 7m for SF4B-F□G<V2> and
SF4B-H□G<V2> (72 to 96 beam channels) and SF4B-A□G<V2> (36 to 48 beam channels).

2-3-2 Safety Distance

Calculate the safety distance correctly, and always maintain the distance which
is equal to or greater than the safety distance, between the sensing area of this
device and the dangerous parts of the machine. If the safety distance is miscal-

culated or if sufcient distance is not maintained, the machine will not stop quickly

before reaching to the dangerous parts, which can result in death or serious injury.

The safety distance is the minimum distance that must be maintained between the device and
the dangerous parts of the machine so that the machine can be stopped before a human body
or an object can reach the dangerous parts.
The safety distance is calculated based on the equation described in the next page when a per­son moves perpendicular (normal intrusion) to the sensing area of the device.

Safety distance S

Sensing area

Dangerous
part

Intrusion direction

Before designing the system, refer to the relevant standards of the region where
this device is to be used, and then install this device.
Furthermore, the equation described in the next pages is to be used only in case
the intrusion direction is perpendicular to the sensing area. In case the intrusion
direction is not perpendicular to the sensing area, be sure to refer to the relevant

standard (regional standard, specication of the machine, etc.) for details of the

calculation.

The max. response time of the machine is from the point that the machine re­ceives the halt signal from this device to the point that the dangerous parts of the
machine stops. The max. response time of the machine should be timed with the
machine to be actually used.

The size of the minimum sensing object for this device varies depending on the

case whether the oating blanking function is applied or not. Calculate the safety

distance with the proper size of the minimum sensing object and appropriate
equation.

For calculating the safety distance S, there are the following ve cases.

●

First calculate by substituting the value K = 2,000 (mm/sec.) in the equation above. Then, classify the ob-

tained value of S into three cases, 1) S < 100, 2) 100 ≤ S ≤ 500, and 3) S > 500.

For Case 3) S > 500, recalculate by substituting the value K = 1,600 (mm/sec.). After that, classify the

calculation result into two cases, 4) S ≤ 500 and 5) S > 500. For details, refer to “Calculation Example 1

For use in Europe.”
When this device is used in the “PSDI Mode,” an appropriate safety distance S must be calculated. For

<Calculation Example>

●

Calculation Example 1: For use in Europe

First, calculate with K = 2,000.
S = K × T + C
= K × (Tm + T

SF4B

) + 8 × (d - 14)
= 2,000 × (Tm + 0.014) + 8 × (14 - 14)
= 2,000 × Tm + 2,000 × 0.014
= 2,000 × Tm + 28

If the result is:

1) In case S < 100 (mm)

Safety distance S is taken as 100 (mm)

2) In case 100 ≤ S ≤ 500 (mm)

Safety distance S is taken as 2,000 × Tm + 28 (mm)

3) In case S > 500 (mm)

SF4B

S = K’ × (Tm + T

) + 8 × (d - 14)
= 1,600 × (Tm + 0.014) + 8 × (14 - 14)
= 1,600 × Tm + 1,600 × 0.014
= 1,600 × Tm + 22.4

then, calculate again.

If the result is:

4) In case S ≤ 500 (mm)

Safety distance S is taken as 500 (mm)

5) In case S > 500 (mm)
Safety distance S is taken as 1,600 × Tm + 22.4 (mm)

In case this device is installed in a system with a maximum halting time of 0.1 (sec.)
S = 2,000 × Tm + 28

= 2,000 × 0.1 + 28
= 228

Since this value matches with Case 2) above, S is 228 (mm).

In case this device is installed in a system with a maximum halting time of 0.4 (sec.)
S = 2,000 × Tm + 28

= 2,000 × 0.4 + 28
= 828

Since this value matches with Case 3) above,
S = 1,600 × Tm + 22.4

= 1,600 × 0.4 + 22.4
= 662.4

Since this value matches with Case 5) above, S is 662.4 (mm).

<Output waveform [control output (OSSD 1 / 2) ON]>

Since the receiver performs the self-diagnosis of the output circuit when the device is in light receiving

status (ON status), the output transistor becomes OFF status periodically. (Refer to the gure below.)

When the OFF signal is fed back, the receiver judges the output circuit as normal. When the
OFF signal is not fed back, the receiver judges either the output circuit or wiring as error, and
the control output (OSSD 1 / 2) maintains OFF status.

Perform the wiring with paying attention to the input response time of the machine to be
connected to this device, since the OFF signal of this device might cause malfunction.

2-5-3 Wiring · Connecting Procedure and Connector Pin Arrangement

Connect the mating cable (with connector on one end or connector on both ends) to the con­nector of the bottom cap cable which is mounted on this device (emitter and receiver).
Wire the other side of the mating cable according to the customer’s application referring to the
connector pin arrangement given below.

When extending the cable, use the exclusive cable up to the total length of 50m (for

●

each emitter / receiver). Extending the cable longer than 50m may cause malfunc­tion, which can result in death or serious injury. Besides, if two sets of the devices are
connected in series, up to total length of 30m (for each emitter / receiver) is allowed
for use, and if three sets of the devices are connected, up to total length of 20m (for
each emitter / receiver) is allowed for use. Extending the cable longer than the length

specied may cause malfunction, which can result in death or serious injury.

In case the muting lamp is used, a total length should be 40m or less (for each

●

emitter / receiver).
When the synchronization + wire (orange) and synchronization - wire (orange

●

/ black) is extended with a cable other than exclusive cable, use a 0.2mm2 or
more shielded twisted pair cable.

2-5-4 Basic Wiring

This is the general conguration using one set of the emitter and receiver facing each other.

The control output (OSSD 1 / 2) turns OFF if the light is blocked, while it automatically turns ON
if receives the light.
The auxiliary output is used to invalid the external device monitor function. At this time, set the
auxiliary output with “negative logic of the control output” (factory setting). The auxiliary output
cannot be connected to external devices.

2-5-6 Series Connection

(Wiring Example of the Control Category 4)

[Connectable up to 3 sets of the devices (however, 192 beam channels max.)]

This is the conguration for connecting multiple sets of emitters and receivers facing each other

in series. It is used when the dangerous part can be entered from two or more directions. If any
of the sets is in light blocked status, the control output (OSSD 1 / 2) turns OFF.

For series connection, connect the emitter and emitter, receiver and receiver re­spectively using the exclusive cable (SFB-CSL□) for series connection. Wrong
connection could generate the non-sensing area, resulting in death or serious in­jury.

2-5-8 Series and Parallel Mixed Connection

(Wiring Example of the Control Category 4)

This is the conguration for connecting multiple sets of emitter and receiver facing each other in

mixed series and parallel combination. It is used when there are two or more dangerous parts
that can be entered from two or more directions. Up to three sets of the devices in total of the
series connection and parallel connection can be connected in combination. However, the total
number of beam channels available is 192. In case of series connection, if any of the sets is in
light blocked status, the control output (OSSD 1 / 2) turns OFF. In case of parallel connection,
for the control output (OSSD 1 / 2), only the set of which light is blocked turns OFF.

For series connection, connect the emitter and emitter, receiver and receiver

●

respectively using the exclusive cable (SFB-CSL□) for series connection as
shown in the figure on the next page. Wrong connection could generate the
non-sensing area, resulting in death or serious injury.
For parallel connection, connect the one receiver to the other connection using

●
the interference prevention line as shown in the gure on the next page. Wrong

connection could generate the non-sensing area, resulting in death or serious

2-6 Adjustment

2-6-1 Beam-axis Alignment

1. Turn ON the power supply unit of this device.

2. Check that the digital error indicator (red) and the fault indicator (yellow) of the emitter and
receiver are OFF respectively.

If the digital error indicator (red) or the fault indicator (yellow) lights up or blinks, refer to

“Chapter 5 Troubleshooting,” and report the symptoms to the maintenance in charge.

3. Loosen the hexagon-socket head bolt for beam axis alignment of the mounting bracket, and
adjust the emitter / receiver so that the beam-axis alignment indicators in the display of the
emitter and receiver light up.

The emitter and the receiver can be ne-adjusted by ±15 degrees.

51 © Panasonic Electric Works SUNX Co., Ltd. 2010 MJE-SF4BGV2 No.0018-69V

<Reference>

The beam-axis alignment indicator indicates the reception status for each section of the device which is
divided into 4 sections.
Also, the A (D) of the beam-axis alignment indicates the light-receiving status of the device top end (bottom
end).
For example, when using a 24-beam channel device, there are 6 beam channels per section (i.e., 24/4=6).
When the top end (bottom end) beam channel is received, the A (D) of the beam-axis alignment indicator
blinks in red.

The indicators corresponding to the different sections light up in red, one by one, when the beam channels
of the respective sections are received. When all the beam channels are received and the control output
(OSSD 1 / 2) turns ON, all the four indicators of the beam-axis alignment indicator turn into green.
Refer to “2-6-2 Operation Test” for details.

5. After the adjustment, tighten the hexagon-socket head bolt for beam-axis alignment of the

mounting bracket. The tightening torque should be 2N·m or less.

6. Tighten the two intermediate supporting brackets [M5 (purchase separately)].
Check, once again, that the beam-axis alignment indicators in the display of the emitter and

receiver do light up.

After the beam-axis alignment is nished, make sure to conrm that all the bolts
are tightened by the specied torque. For the tightening torque of each bolt, refer

to “2-4 Mounting.”

2-6-2 Operation Test

1. Turn ON the power supply unit of this device.

2. Check that the digital error indicator (red) and the fault indicator (yellow) of the emitter and
the receiver are OFF respectively.

If the digital error indicator (red) or the fault indicator (yellow) lights up or blinks, refer to

“Chapter 5 Troubleshooting,” and report the symptoms to the maintenance in charge.

3. Move the test rod (ø14mm for SF4B-F□G<V2>, ø25mm for SF4B-H□G<V2>, ø45mm for
SF4B-A□G<V2>) up and down less than 1,600mm/sec. at three positions, just in front of the
emitter (A), between the emitter and receiver (B), and just in front of the receiver (C).

4. During Step 3 above, check that the control output (OSSD 1 / 2) is in OFF state, and both
the OSSD indicator (red) of the receiver and the operation indicator (red) of the emitter light
up as long as the test rod is present within the sensing area.

● If the behavior of the control output (OSSD 1 / 2) and the turning ON / OFF of the emitter /

receiver indicators do not correspond to the movement of the test rod, refer to “Chapter 5
Troubleshooting,” and report the symptoms to the maintenance in charge.

<Reference>

If the indicators show reception of the light even though the test rod blocks the light, check whether there

3-9 Functions Using Handy Controller (SFB-HC) (Optional)

This device enables to set each function using the handy controller (SFB-HC) (optional). The
settable functions and the factory setting of each function are as follows.
For details, refer to the instruction manual enclosed with the handy controller.

Among the functions, the contents related to the safety distance such as the size of
the minimum sensing object are varied depending on the setting condition. When
setting each function, re-calculate the safety distance, and make enough space larg­er than the calculated safety distance. Failure to do so might cause the accident that
the device cannot stop quickly before reaching the dangerous area of the device,
resulting in the death or serious injury.

Fixed blanking function

●

This function enables to protect the control output (OSSD 1 / 2) from turning into OFF even

though the specic beam channel is blocked.
The factory setting is set to be invalid for the xed blanking function.

Floating blanking function

●

This function enables to protect the control output (OSSD 1 / 2) from turning into OFF even
though the number of the blocked beam channels are lower than that of the setting beam
channels. 1, 2 or 3 beam channels are settable as the blocking beam channels.

The factory setting is set to be invalid for the oating blanking function.

Both xed blanking function and oating blanking function are settable simultaneously.

Emission amount control function

●

The two modes, normal mode and short mode, can be set / changed by controlling the emis­sion amount. The factory setting is set to the normal mode for the emission amount control
function.

5) The intermediate supporting bracket (MS-SF4BG-2) is enclosed with the following devices. The quantity

1 set: SF4B-F□G<V2> … 79 to 127 beam channels
SF4B-H□G<V2> … 40 to 64 beam channels
SF4B-A□G<V2> … 20 to 32 beam channels
2 sets: SF4B-H□G<V2> … 72 to 96 beam channels
SF4B-A□G<V2> … 36 to 48 beam channels

of the enclosed bracket differs depending on the device as follows:

This device enables to set each function by using the handy controller (SFB-HC)
(optional). Among the functions, the contents related to the safety distance such
as the size of the minimum sensing object are varied depending on the setting
condition. When setting each function, re-calculate the safety distance, and make
enough space larger than the calculated safety distance. Failure to do so might
cause the accident that the device cannot stop quickly before reaching the dan­gerous area of the device, resulting in the death or serious injury.

<Reference>

Refer to “3-9 Functions Using Handy Controller (SFB-HC) (Optional)” for details related to the function
setting, or to the instruction manual attached to handy.

Both emitter and receiver are adjusted before shipment, please apply both emitter
and receiver with the same serial No. The serial No. is indicated on the plates of
both emitter and receiver. (Under the model represents the serial No.)

This directive is for an assembly of linked parts or components, en­ergized by an electricity, compressed air or oil pressure, etc. and at

least one of which moves, and a component which fullls a safety

function and is released into the market by itself.

The directives is to any electric or electronic devices which will create more
than a limited amount of RF interference, or will withstand a certain amount

of Electro Magnetic elds while operating as intended within specications

The standards that pertain to machine safety, especially electro­sensitive protective equipment (ESPE).

The standard that specifies the safety-related matters of ma­chine safety / control system. They give roles for level (category)
of structure and fault detection reliability, and for level of safety

future performance capability (PL: Performance Level).

UL standard for safety-related software in programmable components.

The abbreviation for Electro-Sensitive Protective Equipment.

The abbreviation for Output Signal Switching Device.
A component of the light curtain that turns OFF when light of the light
curtain is blocked.

The abbreviation for Final Switching Device.
The component of the machine’s safety related control system that
open-circuits the MPCE circuit when the OSSD operates due to the
light from the light curtain being blocked.

This is a rod for checking the detection capability of this device. It has di­mensions corresponding to the minimum sensing object for this device.

For series connection, the sensor to which the power supply or the output
is connected is called main sensor, and the others are called sub sensor.

For parallel connection, the side where the emission / reception process tim­ings are controlled is called master side, and the others are called slave side.

It is one of the safe status of this device. Operation is stopped if the
self-diagnosis function determines that an irrecoverable failure (OS­SDs do not operate normally, etc.) has occurred. If an emitter is in
lockout condition, it will stop emitting light. If a receiver is in lockout
condition, OSSDs are turned OFF.

It is the minimum distance that must be maintained between the light cur­tain and the dangerous parts of a machine so that the machine can be
stopped before a human body or an object can reach the dangerous parts.

The length of the beam-axis direction that the min. sensing object can be de-

tected. The length from the center of the rst beam channel to the center of the

last beam channel in addition to +10mm (+5mm upward, +5mm downward).
