1-3 Protection Area

1-3-1 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.

The sensing area is the zone formed by the sensing height of the sensor 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□ (12 to 64 beam channels) and SF4B-A□ (6 to 32 beam channels), 0.3 to 7m for SF4B-F□ and SF4B-H□ (72 to 96 beam channels) and SF4B-A□ (36 to 48 beam channels). Take care that the sensing range becomes short after mounting either protection cover (FC-SFBH-□) (optional) or slit (OS-SFBH-□) (optional). Take care that if the sensing range is less than

0.3m, malfunction may occur due to the optical structure.

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 serious injury or death.

Do not use any reflection type or recursive reflection type arrangement.

・

When connecting the sensor, use the correct combination of emitter and receiver (same

・

beam pitch and number of beam channels) and match their top-bottom orientation. Combining different types of emitter and receiver could produce a non-sensing area, which may result in serious injury or death.

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

・

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

1-3-2 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 sufficient distance is not maintained, the machine will not stop quickly before reaching to the dangerous parts, which can result in serious injury or death.

The safety distance is the minimum distance that must be maintained between the light

curtain 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 area sensor.

Dangerous part

Safety distance S

Sensing area

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 perpendicula to the sensing area, be sure to refer to the relevant standard (regional standard, specification 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 part of the machine stops. The max. response time of the machine should be timed with the machine to be actually used.

The applicable pitch of the beam channel for this device varies depending on the case whether the floating blanking function is applied or not, and the size of the minimum sensing object is also changed. The equation differs depending on the case whether the minimum sensing object is larger than φ40mm or not. Calculate the safety distance with the proper size of the minimum sensing object and appropriate equation. <Size of minimum sensing object when applying floating blanking function>

Since the receiver performs the self-diagnosis of the output circuit when the sensor is in light receiving status (ON status), the output transistor becomes OFF status periodically. (Refer to the figure 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, OSSD 2) maintains OFF status.

Since the OFF signal of this device might cause malfunction, perform the connecting paying attention to the input response time of the machine to be connected to this device.

1-5-3 Wiring･Connecting Procedure

Notes: 1) The beam channel is not turned OFF during muting even if it is blocked.

2) In case the blanking function is valid, the operation mode is changed.

3) Since the color of the operation indicator changes according to the ON / OFF state of the control output (OSSD 1, OSSD 2), the operation indicator is marked as [OSSD] on the sensor.

4) The threshold where the control output (OSSD 1, OSSD 2) changes from OFF to ON is applied as ‘100% incident beam intensity’.

Besides, ‘when beam is blocked’ refers to the status that there exists any object blocking beam in the sensing

area.

5) In case of using optional function, the handy controller (SFB-HC) (optional) is required.

6) The manual reset and auto reset are possible to be switched depending on the wiring status.

7) The cable can be extended within 30m (for emitter / receiver) when two sensors are connected with series

connection, within 20m when three sensors are connected with series connection. Furthermore, when the muting lamp is used, the cable can be extended within 40m (for emitter / receiver).

8) The intermediate supporting bracket (MS-SFB-2) is enclosed with the following sensors. The quantity of the

enclosed bracket differs depending on the sensor as follows:

1 set : SF4B-F□･･･Sensor with 79 to 111 beam channels

SF4B-H□･･･Sensor with 40 to 56 beam channels SF4B-A□･･･Sensor with 20 to 28 beam channels

2 sets : SF4B-F127, SF4B-H□･･･Sensor with 64 to 80 beam channels

SF4B-A□･･･Sensor with 32 to 40 beam channels

3 sets : SF4B-H□･･･Sensor with 88 to 96 beam channels

SF4B-A□･･･Sensor with 44 to 48 beam channels

This device enables to set each function by using the handy controller (SFB-HC) (optional). The contents related to the safety distance such as the size of the minimum sensing object, response speed, etc. for some functions might be differed. For setting each function, re-calculate the safety distance and keep proper space larger than safety distance. Not keeping enough space around this device might not stop the machine quickly, resulting in serious bod in

or death.

Refer to ‘2-9 Functions Using Handy Controller (SFB-HC) (Available soon)’ for details related to the function setting, or to the instruction manual attached to handy controller.

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. (The last 5 digits under the model represents the serial No.)
