2-1 Calculation of the minimum distance for installation
Section 2:
Precautions and criteria for installation
The area where the SLC is to be installed must be compatible with the SLC 's technical specifications. The
temperature of the environment, interference caused by electromagnetic disturbance and sources of light
and such like, should be assessed a competent person. Please contact the manufacturer for any information
not contained in this manual.
2-1
Calculation of the minimum distance for installation
The safety distance 'S' must guarantee that the operator cannot reach the danger zone before the machinery
with the moving parts has stopped. The formula to calculate the safety distance for multi-beam SLCs is as
follows:
S = (K * T) + C
S = safety distance.
T = T1 + T2
where T1 = machinery's response time in seconds.
T2 = SLC's response time in seconds.
K = 1600 mm/s (approach speed of the body to the danger zone).
C = 850 mm
S = safety distance.
H1 = the bottom optical beam must not have a height above 400 mm.
H2 = the top optical beam must not be below 900 mm.
!
Do not use F3S-TGR-SBx-KxC series in horizontal position.
