Protection Area
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, never use this device facing several receivers towards one emitter or vice versa.
The sensing area is the zone formed by the sensing height (protective height) of the device and the valid
range between the emitter and the receiver. The sensing height (protective height) is determined by the number of beam channels. Furthermore, the valid range can be 0.1 to 3m.
Take care that if the valid range is under 0.1m, malfunction may occur due to the optical structure.

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 miscalculated 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 this 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.

<Reference>
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 obtained 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 details, be sure to refer to the standards or regulations applicable in each region or country.

<Calculation example>
Calculation example 1: For use in Europe
(OFF response time: 7ms or less, minimum sensing object diameter: 25mm)
First, calculate with K = 2,000.
S= K × T + C
= K × (Tm + TSF4C) + 8 × (d - 14)
= 2,000 × (Tm + 0.007) + 8 × (25 - 14)
= 2,000 × Tm + 2,000 × 0.007 + 8 × 11
= 2,000 × Tm + 14 + 88
= 2,000 × Tm + 102
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 + 102 (mm)
3) In case S > 500 (mm)
S = K’× (Tm + TSF4C) + 8 × (d - 14)
= 1,600 × (Tm + 0.007) + 8 × (25 - 14)
= 1,600 × Tm + 1,600 × 0.007 + 8 × 11
= 1,600 × Tm + 11.2 + 88
= 1,600 × Tm + 99.2
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 + 99.2 (mm)
In case this device is installed in a system with a maximum halting time 0.1 (sec.)
S = 2,000 × Tm + 102
= 2,000 × 0.1 + 102
= 302
Since this value matches with the case 2) above, S is 302 (mm).
In case this device is installed in a system with a maximum halting time 0.4 (sec.)
S = 2,000 × Tm + 102
= 2,000 × 0.4 + 102
= 902
Since this value matches with the case 3) above,
S = 1,600 × Tm + 99.2
= 1,600 × 0.4 + 99.2
= 739.2
Since this value matches with the case 5) above, S is 739.2 (mm).

Equation 2
DS = K × (TS + TC + TSF4C + Tbm) + Dpf
DS : Safety distance (mm)
Minimum required distance between the sensing area surface and the dangerous parts of the
machine
K
: Intrusion speed {Recommended value in OSHA is 63 (inch/sec.) [ 1,600 (mm/sec.)]}
ANSI/RIA 15.06 does not de ne the intrusion speed “K”. When determining K, consider possible factors including physical ability of operators.
TS : Halting time calculated from the operation time of the control element (air valve, etc.) (sec.)
TC : Maximum response time of the control circuit required for functioning the brake (sec.)
TSF4C: Response time of this device (sec.)
Tbm : Additional halting time tolerance for the brake monitor (sec.)
The following equation holds when the machine is equipped with a brake monitor.
Tbm = Ta - (TS + TC)
Ta: Setting time of brake monitor (sec.)
When the machine is not equipped with a brake monitor, it is recommended that 20% or more
of (TS + TC) is taken as additional halting time.
Dpf : Additional distance calculated from the size of the minimum sensing object of the device (mm)
Dpf = 61.2mm
Dpf = 3.4 × (d - 0.276) (inch)
3.4 × (d - 7) (mm)
d: Minimum sensing object diameter 0.985 (inch) 25 (mm)

[OFF response time: 7ms or less, minimum sensing object diameter: 0.985 (inch)
S = K × (TS + TC + TSF4C + Tbm) + Dpf
= 63 × (Ta + 0.007) + 3.4 × (d - 0.276) (inch)
= 63 × (Ta + 0.007) + 3.4 × (0.985 - 0.276)
= 63 × Ta + 63 × 0.007 + 3.4 × 0.709
= 63 × Ta + 0.441 + 2.4106
= 63 × Ta + 2.8516

20 (mm)]
In case this device is installed in a system with a maximum halting time 0.1 (sec.)
S = 63 × Ta + 2.85
= 63 × 0.1 + 2.85
= 9.15 (inch)
232.41 (mm)
Hence, as per the calculations S is 232.4 (mm).

<Output waveform [when control output (OSSD 1 / 2) is 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.

2-6-1 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 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. Loosen the hexagon-socket head bolts [M5 (please arrange separately)] which holds the standard mounting bracket MS-SFC-1.
4. Move the emitter in the left and right directions in order to determine the range of the light received condition with the help of the beam-axis alignment indicator (red). Then, set the emitter at the center of this
range.
5. Similar to the step 4, perform the beam-axis alignment for the receiver.
6. Tighten the standard mounting bracket MS-SFC-1 by the hexagon-socket head bolt [M5 (please arrange
separately)].
7. Check, once again, that the beam-axis alignment indicators (red), operation indicator (green) and OSSD
indicator (green) in the display of the emitter and receiver do light up.

<Reference>
The beam-axis alignment indicator indicates the reception status for each section of the device which is divided into 4
sections.
Furthermore, 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 16-beam channel device, there are 4 beam channels per section (i.e., 16/4=4).
When the top end (bottom end) beam channel is received, the A (D) of the beam-axis alignment indicator blinks in red.
(Example) 16 beam channels

“for Industrial Robots and Robot Systems - Safety Requirements, 10.4.5 Muting”
Use the muting control while the machine cycle is not in danger mode. Maintain safety with the other
measure while the muting control is activating.
For the application that the muting control is activated when a sensing object passes through the
sensor, place the muting sensor so that the conditions for the muting control cannot be satis ed by
intrusion of personnel when the sensing object is passing through the sensor or the sensing object is
not passing through it.
The muting lamp should be installed in a position where it can always be seen by operators who set
or adjust the machine.
Be sure to check the operation of the muting function before its use. Furthermore, check the state of
the muting lamp (cleanliness or brightness etc.)
This function turns the safety function into invalid temporarily. When the control output (OSSD 1 / 2) is ON, this function is available for passing the sensing object through the sensing area of the device without stopping the device.
The muting function becomes valid when all the conditions listed below are satis ed:
The control output (OSSD 1 / 2) shall be ON.
The safety output 1 / 2 shall be ON.
Time difference between the time during muting input 1 / 2 becomes ON from OFF (open) and the time
during muting input 1 / 2 becomes OFF (open) from ON should be between 0.03 to 3 sec.
The following devices, photoelectric sensor with semiconductor output, inductive proximity sensor, position
switch on NO (Normally Open) contacting point, etc. are available for applying to the muting sensor.
