2-16 Installation and Checkout
The mounting location you choose for your Shadow 8 heads must meet the following
requirements:
•
It must be impossible for anyone to reach over, under, or around the light curtains and into
the hazardous area of the press without being detected.
•
Light curtains should not be mounted near pathways used by forklifts, die carts, and other
material-handling equipment.
•
The mounting location must allow unobstructed access to the point-of-operation.
•
Light curtains must be mounted an adequate safety distance from the pinch point to allow
time for the press to stop once the light curtain has been interrupted (see Calculating the
Safety Distance, page 2-2).
•
The mounting location must be chosen so that every route to the press’s pinch point or
hazardous area is guarded.
The Shadow 8 Main Transmitter and Receiver by themselves provide guarding on one side
of the press. Mirrors used with Shadow 8 can provide 3-sided protection by “bending” the
light curtain around the hazardous point-of-operation. Extension heads can also be used
for multi-sided guarding. When Shadow 8 mirrors or Extensions are not used in
conjunction with the Main light curtains, however, other guarding means, such as
mechanical side-guards, must be substituted for them, in accordance with OSHA/ANSI
guidelines.
Designing and Installing Mounting Brackets and Floor Stands
Shadow 8 light curtains can be mounted on floor stands or to brackets on your machinery,
using the Shadow 8 universal mounting brackets on the top and bottom of each unit.
Stands in various heights are available from Wintriss (see Figure 2-4 and Table 2-1,
page 2-17). Wintriss does not supply brackets, so you must provide your own.
Information about designing and mounting your own brackets as well as where you can buy
brackets is available from Wintriss Tech. Support.
Brackets and stands must meet the following conditions:
•
They must provide a rigid mounting surface for the Shadow 8 heads. Brackets must be
made of strong, thick steel. Stands must be rigidly attached to the floor.
•
They must bring the heads out far enough from the point of operation so that they are at or
beyond the calculated safety distance.
•
They must allow the heads to be easily aligned.
•
They must allow shock mounts to be used to install the optic heads. Four shock mounts are
shipped with each head.
