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.

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.

For NPN output (plus ground)

In the above diagram, set the safety light curtain input polarity selection switch to the NPN side and ground the + side.

When SF-C11 is connected to the safety light curtain, be sure to use the following mating cable.

Cautions For Use

Interlock function

The selection of manual reset / automatic reset is available by applying the interlock input wiring. The interlock becomes available by selecting manual reset.
(Refer to the SF4B / SF4B-G instruction manual for details.)

Emission halt function

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 emission halt input / reset input wire (pink).
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.
Normal operation is restored when the emission halt input / reset input wire (pink) is connected to 0 V or +V.
(Refer to the SF4B / SF4B-G instruction manual for details.)

Auxiliary output (Non-safety output)

This safety light curtain incorporates the auxiliary output (yellowgreen / black) for the non-safety output. The auxiliary output is incorporated with the emitter.
(Refer to the SF4B / SF4B-G instruction manual for details.)

External device monitoring function

This is the function for checking whether the external safety relay connected to the control outputs (OSSD 1, OSSD 2) perform normally in accordance with the control outputs (OSSD 1, OSSD 2) or not. Monitor the contacting point “b” 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). (Refer to the SF4B / SF4B-G instruction manual for details.)

Muting function

This function turns the safety function of this safety light curtain into disabled temporarily. When the control outputs (OSSD 1, OSSD 2) are ON, this function is available for passing the workpiece through the sensing area of the safety light curtain without stopping the machinery.
The muting function becomes valid when all the conditions listed below are satisfied.
However, this function connot be used with the SF4B-□-03.
①The control outputs (OSSD 1, OSSD 2) shall be ON.
②The incandescent lamp with 3 to 10 W shall be connected to the muting lamp output (red).
③The output of the muting sensors A and B shall be changed from OFF (open) to ON. At this time, the time difference occurred by changing the output of the muting sensors A and B into ON status shall be within 0.03 to 3 sec.
The following devices, photoelectric sensor with semiconductor output, inductive proximity sensor, position switch on N.O. (Normally open) contact, etc.
are available for applying to the muting sensor.
In case of using the muting function, please order 12-core cable.
(Refer to the SF4B / SF4B-G instruction manual for details.)

Override function

This function sets the safety function of this safety light curtain enabled forcibly.
When using the muting function, the override function can be used to start the machinery at times such as when the control outputs (OSSD 1 and OSSD 2) are OFF or when the muting sensors are ON when the line is to be started.
The override function becomes valid when all the conditions listed below are satisfied. However, this function cannot be used with the SF4B-□-03<V2>.
(Refer to the SF4B / SF4B-G instruction manual for details.)

Series connection

Connectable up to 3 sets of safety light curtains
(however, 192 beam channels max.)

(Refer to the SF4B / SF4B-G instruction manual for details.)

Parallel connection

Connectable up to 3 sets of safety light cartains

(Refer to the SF4B / SF4B-G instruction manual for details.)

Series and parallel mixed connection

Connectable up to 3 sets of safety light curtains
(however, 192 beam channels max.)

(Refer to the SF4B / SF4B-G instruction manual for details.)

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 sec.) after the power supply is switched on.
Avoid dust, dirt and steam.
Take care that the safety light curtain does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.
Take care that the safety light curtain is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing erformance.

This catalog is a guide to select a suitable product. Be sure to read instruction manual prior to its use.
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. (Indicated under model No.)

Make sure to carry out the test run before regular operation.
This safety system is for use only on machinery in which the dangerous parts can be stopped mmediately, either by an emergency stop unit or by disconnecting the power supply. Do not use this system with machinery which cannot be stopped at any point in its operation cycle.

Sensing area

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.

The sizes of the minimum sensing objects for this device vary depending on whether or not the floating blanking function is being used. Calculate the safety distance with the proper size of the minimum sensing object and appropriate equation.

Note: Refer to ORDER GUIDE for the floating blanking function. However, the floating blanking function cannot be used with the SF4B-□-01<V2>, the SF4B-□-03<V2> and the SF-C14EX-01.

The safety distance is calculated using the equations given on the following pages when a person moves perpendicularly (normal intrusion) into the sensing area of the device.
If the intrusion direction is not perpendicular, always check the related standards (regional, machine standards, etc.)

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

For intrusion direction perpendicular to the sensing area
<In case that the minimum sensing object is ø40 mm ø1.575 in or less>

• Equation① 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 velocity of operator’s body or object (mm/sec.)
Normally taken as 2,000 (mm/sec.) for calculation

T:
Response time of total equipment (sec.)
T=T_m+T_SF4B
T_m：Maximum halting time of machinery (sec.)
T_SF4B：Response time of the SF4B / SF4B-G series (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 less than 0.
C= 8 × (d – 14)
d: Minimum sensing object diameter (mm)

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 < = 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 calculating “Tm” (maximum halt time of the machinery), use a special device called a “brake monitor”.
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.
