Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of + 20 ℃ + 68 ℉.
2) Due to revisions of safety light curtain standards (Electro-sensitive protective equipment), type 2 safety light curtains are limited to PLc and SIL1regarding PL and SIL standards.
3) Not compatible when using the bottom cap cable SF2B-CB05-A.
4) When using auxiliary output (AUX), the compatible cable SF2B-CB05-B (sold separately) cannot be used.
5) SF2B-H8-□ and SF2B-A4-□ cannot be connected in series.
6) When making series connection mixing SF2B-H□ and SF2B-A□, calculate by doubling the number of optical axes only for SF2B-A□, and make the total number of optical axes fall below 128 axes.
(e.g.) When making series connection with SF2B-H36 and SF2B-A44, the total number of optical axes will be 124 axes. The number of optical axes for
SF2B-H36 + (number of optical axes for SF2B-A44 x 2) = total number of optical axes. 36 optical axes + (44 optical axes x 2) = 124 optical axes.

SF-C11

SF2B series wiring diagram (Control category 2)

For NPN output (plus ground)

Set the safety light curtain input polarity selection switch to the NPN side and ground the + side.

Notes:

1) The above diagram is when using manual reset. If automatic reset is used, disconnect the lead from X2 and connect it to X3. In this case, a reset (RESET) button is not needed.

2) Use a momentary-type switch as the reset (RESET) button.

3) Emission halt occurs when the test (TEST) button is open, and emission occurs when the test (TEST) button is short-circuited. If not using the test (TEST) button, short-circuit T1 and T2. However, use a test rod or similar to interrupt the light in order to carry out self-diagnosis separately.

For PNP output (minus ground)

Set the safety light curtain input polarity selection switch to the PNP side and ground the 0 V line.

Notes:

1) The above diagram is when using manual reset. If automatic reset is used, disconnect the lead from X2 and connect it to X3. In this case, a reset (RESET) button is not needed.

2) Use a momentary-type switch as the reset (RESET) button.

Be sure to use the following mating cables when connecting SF-C11 to
SF2B series.

Self-diagnosis function

This safety light curtain incorporates the self-diagnosis function. In case an abnormality is detected during self-diagnosis, the safety light curtain is put in the lockout state at that instant, and the control output (OSSD 1, OSSD 2) is fixed at the OFF state. Refer to “Troubleshooting” and the instruction manual and remove the cause of the abnormality.

In order to maintain safe condition of safety light curtain, inspect the beam interrupted status of the device once a day or more. Failure to do so could delay the detection of unexpected abnormality and increase the degree of hazard, which may cause the malfunction of safety light curtain, resulting in serious body injury or death.
In order to check all abnormalities in the OSSD 1, OSSD 2 and auxiliary output, the beam interrupted status of device must be checked. Perform either of two below to inspect the device under beam interrupted status.
Emission halt by test input (Emission halt function)
Beam interrupting by test rod (Excluding the cable SF2B-CB05-A)
・Emission halt by test input (Emission halt function)
・Beam interrupting by test rod (Excluding the cable SF2B-CB05-A)

Emission halt function (Test input)

This function stops the emission process of the emitter. You can select whether emission is on or halted by means of the connection status for the test input (pink).

Test input	Emission status
Test input		When using the SF2B-CB05-B
Open	Emission halt	Emission
Connected to 0 V or +V	Emission	Emission halt

During emission halt, the control outputs (OSSD 1, OSSD 2) become OFF status.
By using this function, malfunction due to extraneous noise or abnormality in the control outputs (OSSD 1, OSSD 2) and the auxiliary output can be determined even from the machinery side.

Auxiliary output

Auxiliary output is incorporated into the emitter and its operation varies depending on the type of bottom cap cable (optional) to be used.

Bottom cap cable	Normal mode			Lockout
	Emission halt	Control outputs (OSSD 1, OSSD 2) status
	Emission halt	Beam received	Beam interrupted
When using the SF2B-CCB□ / SF2B-CB□	ON	OFF	ON	ON
When using the SF2B-CB05-A	OFF	ON	ON	OFF
SF2B-CB05-B	Cannot be used.

When bottom cap cable SF2B-CCB□ or SF2B-CB□ (optional) is used

The auxiliary output is incorporated in the emitter. It is OFF when the control outputs (OSSD 1,OSSD 2) are ON and vice versa.
The auxiliary output can be used as an operation monitor of the device.
When the external device monitor function is not used, connect the external device monitor input line to the auxiliary output line to disable the function.
In this case, do not connect the load to the auxiliary output. For details, refer to “External device monitoring function” and “I/O CIRCUIT AND WIRING DIAGRAMS”.
When the external device monitoring function is used to disable, do not directly use the auxiliary output as the operation monitor of this safety light curtain. When the external device monitor is used to disable and the auxiliary output is used to monitor the operation of safety light curtain, connect the auxiliary output and the external device monitoring input to the external relay (purchase separately) to use the external relay contacting point as an operation monitor of this safety light curtain.

When bottom cap cable SF2B-CB05-A (optional) is used

The auxiliary output is incorporated in the emitter. It outputs ON at the normal operation of device. It outputs OFF in the following cases:
・When an abnormality which needs emission halt status occurs [for example, the control output (OSSD 1) short-circuit and an error occurs.]
・While test input has been input
The error cannot be transmitted to the control machine. The alarm signal is output from the auxiliary output.

When bottom cap cable SF2B-CB05-B (optional) is used

The auxiliary output cannot be utilized by using the bottom cap cable SF2B-CB05-B (optional).

External device monitoring function

This function is available when the bottom cap cable SF2B-CCB□ or SF2B-CB□ (optional) is used. This is the function for checking whether the external safety relay connected to the control outputs (OSSD 1, OSSD 2) performs normally in accordance with the control outputs (OSSD 1, OSSD 2) or not. Monitor the b contact of the external safety relay, and if any abnormality such as deposit of the contacting point, etc. is detected, change the status of the safety light curtain into lockout one, and turn OFF the control outputs (OSSD 1, OSSD 2).

In case of setting the external device monitoring function to enabled

Connect the external device monitoring input (yellow-green) to the b contact of the external safety relay that is connected to the control outputs (OSSD 1, OSSD 2).

In case of not using the external device monitoring function

Connect the external device monitoring input (yellow-green) to the auxiliary output (yellow-green / black).

The time set for external device monitoring is 300 ms or less. Exceeding 300 ms turns the safety light curtain into lockout condition.

Series connection

Connectable up to 3 sets of safety light curtains (however, 128 beam channels max.) (Note 1, 2)

This is the configuration 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. The control outputs (OSSD 1, OSSD 2) turns OFF if any of the safety light curtain is interrupted. For details, refer to the instruction manual.

Notes:

1): Series connection connectors cannot be used with the SF2B-H8-□ and SF2B-A4-□, and so series connection is not possible. The SF2B-H8SL and SF2B-A4SL are not equipped with series connection connectors, so when connecting three sets in series, they cannot be used in the middle position.

2): The total number of beam axes for the SF2B-A□ is a maximum of 96 when two sets are connected, and 64 when three sets are connected. When SF2B-H□ and SF2B-A□ are combined in series connection, double the number of the beam channels of SF2B-A□ to calculate the total number of beam channels, which should be 128 or less.
Example:
The total no. of beam channels for SF2B-H36 and SF2B-A44 is 124. The no. of beam channels of SF2B-H36 + (the No. of beam channels of SF2B-A44 × 2) = Total no. of beam channels 36 beam channels + (44 beam channels × 2) = 124 beam channels

Parallel connection

Up to a maximum of two sets can be connected in parallel only when using the SF2B-CB05-B adapter cable (optional). For details, refer to the instruction manual.

*Set the frequency selection switches (for both emitter and receiver) to “1” at the master units, and set them to “2” at the slave units.

Series and parallel mixed connection

Up to a maximum of three sets can be connected in a mixture of series and parallel (for a total maximum number of 128 beam channels. However, the total number of beam channels for the SF2B-A□ is a maximum of 96 when two sets are connected, and 64 when three sets are connected.) only when using the SF2B-CB05-B adapter cable (optional). For details, refer to the instruction manual.

*Set the frequency selection switches (for both emitter and receiver) to “1” at the master units, and set them to “2” at the slave units.

Wiring

Make sure to carry out the wiring in the power supply off condition.
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this sensor, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

Others

This device has been developed / produced for industrial use only.
Do not use during the initial transient time (2 s) after the power supply is switched on.
Avoid dust, dirt and steam.
Take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.
Take care that the sensor is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance.

Sensing area

Make sure to install this product such that any part of the human body must pass through its sensing area in order to reach the dangerous parts of the machinery. If the human body is not detected, there is a danger of serious injury or death.
Do not use any reflective type or retroreflective type arrangement.
Emitter and receiver that face each other should be from the same model No. (with same beam axis pitch and number of beam channels) and aligned in the vertical direction. If units from different sets are connected together, it may cause blind spots in the sensing area, and death or serious injury may result.
Do not connect facing several receivers towards one emitter.

Calculate the safety distance correctly, and always maintain a distance which is equal to or greater than the safety distance, between the sensing area of this safety light curtain and the dangerous parts of the machinery. (Please check the latest standards for the equation.) If the safety distance is miscalculated or if sufficient distance is not maintained, there is a danger of serious injury or death.
Before designing the system, refer to the relevant standards of the region where this device is to be used and then install this device.

Safety distance is calculated based on the following equation when a person moves perpendicular (normal intrusion) to the sensing area of the safety light curtain. In case the intrusion direction is not perpendicular to the sensing area, be sure to refer to the relevant standard (regional standard, specification of the machine, etc.) for details of the calculation. (Please check the latest standards for the equation.)

For use based on EN ISO 13855 / ISO 13855 / JIS B 9715

For intrusion direction perpendicular to the sensing area
Equation 1 S = K × T + C
S: Safety distance (mm)
Minimum required distance between the sensing area surface and the dangerous parts of the machine
K: Intrusion speed of operator’s body or objects (mm/sec.)
Normally, taken as SF2B-H□ 2,000 (mm/sec.),
SF2B-A□ 1,600 (mm/sec.) for calculation.
T: Response time of total equipment (sec.)
T = Tm + TSF2B
Tm: Maximum halting time of machinery (sec.)
TSF2B: Response time of the SF2B series 0.015 (sec.)
C: Additional distance calculated from the size of the minimum sensing object of the safety light curtain (mm)
However, the value of “C” cannot be 0 or less.
C = 8 × (d – 14)
d: Minimum sensing object diameter
SF2B-H□: d= 27 (mm) 1.063 (in), C = 104 (mm) 4.094 (in)
For SF2B-A□, C = 850 (mm) 33.465 (in) (constant)

・For calculating the safety distance “S”, there are the following five 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 the instruction manual enclosed with this product.

For use based on ANSI B11.19

Equation 2 S = K × (Ts + Tc + TSF2B + Tbm) + Dpf
S: Safety distance (mm)
Minimum required distance between the sensing area surface and the dangerous parts of the machine
K: Intrusion velocity {Recommended value in OSHA is 63 (inch/sec.)
≈ 1,600 (mm/sec.)}
ANSI B11.19 does not define the intrusion velocity “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.)
TSF2B: Response time of safety light curtain 0.015 (sec.)
Tbm: Additional halting time tolerance for the brake monitor (sec.)
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 safety light curtain
SF2B-H□ Dpf = 2.676 (inch) ≈ 68 (mm)
SF2B-A□ Dpf = 5.355 (inch) ≈ 136 (mm)
　 Dpf = 3.4 × (d – 0.276) (inch)
　 Dpf ≈ 3.4 × (d – 7) (mm)
　 d: Minimum sensing object diameter 1.063 (inch) ≈ 27 (mm) SF2B-H□
　 Minimum sensing object diameter 1.851 (inch) ≈ 47 (mm) SF2B-A□
