Calculating the Safety Distance according to ISO 13855
基本计算示例

安装时安全灯幕or other electrical detection protective device, refer to the在到达危险区域之前停止机器之前停止机器的最低距离when the body enters the detection zone. These distances are defined in standards such as ISO 13855. When installing a light curtain, be sure to provide the safety distance (minimum distance) determined by sources such as the standards, regulations, and laws of the country or area in which the light curtain will be used.

Calculating the Safety Distance according to ISO 13855

Safety distance (S) = Approach speed of the body × response time + additional distance (which varies depending on the detection capability of the sensor)

Perpendicular direction of approach

Detection of the body: S= k×t + c 40 1.57“; k = 1600 mm 62.99“/s(approach speed [assuming the walking speed of a person])
T = Maximum time required by the machine to stop + response time of the light curtain
C = 850毫米33.46英寸（渗透距离[与人臂的标准长度匹配的值））
Detection of fingers and hands: S=K × T + 8(d - 14) d ≤ 40
S = K×T + 8（D -0.55“）D≤1.57”; k = 2000毫米78.74“/s（接近速度[假设手的穿透速度]）
T = Maximum time required by the machine to stop + response time of the light curtain
d =灯罩的检测能力

注意：如果S大于或等于500 mm 19.69“，请再次以K等于1600 62.99的k进行计算。如果新计算的结果给出了S少于或等于500 mm 19.69“，则设置为500毫米19.69”。

机器停止所需的最长时间与安全距离之间的关系

公式中显示的值t是通过添加以下两个参数来形成的。　T = Maximum time required by the machine to stop + response time of the light curtain (ON → OFF)

例如，当K（穿透速度）= 2000 mm 78.74“/s时，使用GL-R08H灯窗帘（其响应时间为0.0069 s）时
S = 2000毫米78.74“/s×）（机器需要停止 + 0.0069 s） + C

As shown above, the maximum time required by the machine to stop is multiplied by the penetration speed (2000 mm 78.74"/s), so if the maximum time required by the machine to stop is increased by just 1 second, the safety distance is increased by (2000 mm 78.74"/s × 1 s = 2000 mm 78.74"). If the light curtain’s response time is increased by 1 ms, the safety distance is increased by 2 mm 0.08".

基本计算示例

垂直方向的方法：GL-R系列

Formula：S = K × T + C

S：最小距离（mm英寸；请参见下图），S≥100mm 3.94”
K: Parameter extracted from the data based on the approach speed of the body (mm inch/s)
T: Overall system stop performance (s)
T = t1 (GL-R Series maximum response time) + t2 (maximum time required by the machine to stop)
C:Penetration distance (mm inch)
当D≤40：8×（D -14）带有C≥0
当40 When d ≤ 1.57":8 × (d - 0.55") with C ≥ 0"
When 1.57" < d ≤ 2.76": 33.46"
d: Detection capability of the GL-R Series (mm inch)

计算示例（1）-1 使用GL-R60H时 (detection capability d = 25 mm 0.98" and 60 beam axes): Condition: Industrial application
K = 2000 mm 78.74"/s
T1（GL-R60H响应时间）= 0.0157S
t2(所需的最长时间机器停止)= 0.1s
C = 8 × (25 - 14) = 88 mm 8 × (0.98" - 0.55") = 3.46"

S = K × T + C = 2000 ×（0.1157）+ 88 = 319.4mm
S = K × T + C = 78.74" × (0.1157) + 3.46" = 12.57"

If S is greater than 500 mm 19.69", perform the calculation again with K equal to 1600 mm 62.99"/s. If the newly calculated result gives S less than or equal to 500 19.69", set S to 500 19.69".
计算示例（1）-2 When using the GL-R08L （检测能力d = 45 mm 1.77英寸和8梁轴）: Condition: Industrial application
k = 1600 mm 62.99“/s
T1（GL-R08L响应时间）= 0.0069 S
t2(所需的最长时间机器停止)= 0.1 s
C = 850毫米33.46“

S = K × T + C = 1600 × (0.1069) + 850 = 1021.04 mm
S = K×T + C = 62.99“×（0.1069） + 33.46” = 40.20”

方法的平行方向：GL-R系列

Formula：S = K × T + C

S：最小距离（请参阅下图）
K: Parameter extracted from the data based on the approach speed of the body (mm inch/s)

15（D -50）≤H≤1000，H≥0
(d - 1.97") ≤ H ≤ 39.37" with H ≥ 0"

Calculation Example (2)-1 When using the GL-R30L (detection capability d = 45 mm 1.77" and 30 beam axes): Condition: Industrial application
k = 1600 mm 62.99“/s
T1（GL-R30L响应时间）= 0.0105 s
t2(所需的最长时间机器停止)= 0.1 s
H = 200 mm 7.87“
C = 1200 - 0.4 × 200 = 1120 mm
C = 47.24“ -0.4×7.87” = 44.09“
S = K × T + C = 1600 × (0.0105 + 0.1) + 1120 mm = 1296.8 mm
S = K×T + C = 62.99“×（0.0105 + 0.1） + 44.09” = 51.06”

通过规避检测区的顶部来接近危险：GL-R系列

When it is not possible to prevent people from passing over the top of the detection zone in order to approach the hazardous zone, it is necessary to determine the height of the light curtain and the minimum distance S while keeping this issue in mind. You have to compare the S value calculated as shown below and the S value calculated under “Perpendicular Direction of Approach: GL-R Series” and set the larger value as the minimum distance S.

Formula：S = K × T + C_RO

S：最小距离（毫米英寸；请参见右侧的图），S≥100mm 3.94”
K: Parameter extracted from the data based on the approach speed of the body (mm inch/s)
K is determined according to the following table on the basis of S.

S（mm英寸）	K（mm英寸/s）
100 ≤ S ≤ 500 3.94" ≤ S ≤ 19.69"	2000 78.74“
500 < S 19.69" < S	1600 62.99”

如下表所示，根据值A（危险区的高度）和B（灯幕的检测区的高度）确定CRO。

*1 Situations in which the height of the top of the detection zone is less than 900 mm 35.43" are not included because they cannot provide sufficient protection against circumvention and straddling.
*2 If the bottom of the detection zone is at a height of more than 300 mm 11.81" from the reference plane, sufficient protection cannot be provided against passing under the detection area to approach the hazard.

计算示例（3）-1 使用GL-R60H时 （检测能力d = 25 mm 0.98英寸，60梁轴，检测高度为1180 mm 46.46”）

Condition: Industrial application
A（危险区的高度）= 1400 mm 55.12“
b（灯罩检测区的顶部高度）= 1180 + 300 = 1480 mm 46.46“ + 11.81” = 58.27“

根据上表，CRO为850毫米33.46”。
（因为B是1480毫米58.27英寸，所以它在1400 55.12“和1600 62.99”之间。在这种情况下，使用B值1400 55.12”。）。

k = 1600 mm 62.99“/s
t1 (GL-R60H response time) = 0.0157 s
t2(所需的最长时间机器停止)= 0.1 s

S = K × T + CRO = 1600 × (0.1157) + 850 = 1035.12 mm 62.99" × (0.1157) + 33.46" = 40.75"
(This is larger than the S value calculated under “Perpendicular Direction of Approach: GL-R Series.”)

计算示例（3）-2 When using the GL-R80H (detection capability d = 25 mm 0.98", 80 beam axes, and detection height of 1580 mm 62.20")

Condition: Industrial application
A（危险区的高度）= 1400 mm 55.12“
b (height of the top of the detection zone of the light curtain) = 1580 + 300 = 1880 mm 62.20" + 11.81" = 74.02"

According to the above table, CRO is 0 mm 0".
（因为B是1880毫米74.02“，所以它在1800 70.87“和2000 78.74”之间。在这种情况下，使用B值1800 70.87”。）。

K = 2000 mm 78.74"/s
t1 (GL-R80H response time) = 0.0192 s
t2(所需的最长时间机器停止)= 0.1 s

S = K × T + CRO = 2000 × (0.1192) + 0 = 238.4 mm 78.74" × (0.1192) + 0" = 9.39"
（这小于在“方法的垂直方向：GL-R系列”下计算的S值。）
