Specifications
Example with Light Curtain LSP29-700, with 700 mm protective height and resolution of 29 mm.
K = 2,000 – value considered for Light Curtain.
Tm = 0.07 – value example of machine stop speed.
Tc = 0.030 – response time value of model selected.
d = 29 – detection capability.
Then, replace the formula, we have:
S = 2,000 x (0.07 + 0.030) + 8 x (29 - 14).
S = 320 mm.
Example with multiple Beam Device LSP300-900, with 4 beams and 300 mm of beam spacing.
K = 1,600 – value considered for multiple Beam Device.
Tm = 0.07 – value example of machine stop speed.
Tc = 0.013 – response time value of model selected.
C = 850 – standard arm reach.
Then, replace the formula, we have:
S = 1,600 x (0.07 + 0.013) + 850.
S = 983 mm.
ATTENTION!
When the value of S found is above than 500 mm, suitable mechanical protection
must be provided because at this distance above of 500 mm, a person can be
positioned between the light curtain and the danger point, without being detected.
