Chapter 6 Installation and Wiring
Do not over-torque the mounting hardware:
•
The required screwdriver type for installation of the plug-ins is a Phillips
tip screwdriver for M2 x 8 Phillips screw. Maximum torque is 0.38 N•m
(3.36 lb•in).
•
The required screwdriver type for installation of the standard top/
bottom mounting kit is a Phillips tip screwdriver for M3 x 10 Phillips DIN
965 A screw. Maximum torque is 0.7 N•m (6.19 lb•in).
Only use the designated mounting holes of the mounting bracket.
Use only fixed, stable, and sturdy mounting posts or frames to mount a 450L-B
GuardShield safety light curtain system.
For the installation of the plug-ins, see
Electrical Installation on page 81
.
Determine the Safety
Distance
The light curtain must be mounted with proper safety distance:
•
From the point of danger
•
From reflective surfaces
To help prevent a person from reaching through the protective field to a
dangerous area (while the machine is still moving), both points must be
considered in an installation.
The calculation of point one varies depending on the region (country) where it
is operated.
U.S. Safety Distance Formula
This distance, referred to as the safety distance, must be properly calculated
before determining the safety light-curtain protective height and mounting
the light curtains on the machine. Failure to calculate this safety distance
properly can result in operator injury.
Regardless of the calculated safety distance, the protective field of a
GuardShield safety light curtain is never mounted closer than 152.4 mm (6 in.)
from the point of operation to the pinch point hazard.
In the United States, two formulas are commonly used to calculate the safety
distance.
•
The OSHA formula is the minimum requirement for the calculation of
the safety distance.
•
The ANSI formula, the formula we recommend, incorporates additional
factors for consideration when calculating the safety distance.
ATTENTION:
The GuardShield safety light curtains must be mounted at a
sufficient distance from the pinch point or point of operation hazard. This
distance helps confirm that the machine stops before a finger, hand, arms, or
body reach the hazard.
