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>
