Calculating the Safety Distance
Once you know your press’s stopping time, you can calculate the safety distance at which to
mount your Shadow light curtains (see the applicable Shadow user manual for more
information). The safety distance is the minimum distance from the pinch point (or hazardous
area) of the press at which light curtains can be installed and still be able to stop the press
before the operator can penetrate the light beam and reach the pinch point (see Figure 6-21).
Before you can switch to Run mode, a tool must be programmed and loaded in Program
mode (see TOOL MANAGER, page 5-2).
OBSERVE THE CORRECT SAFETY DISTANCE
• Calculate the safety distance carefully according to the instructions below, and mount your light
curtain heads at least the calculated distance from the hazardous area.
• Mount your light curtain heads at least 7.5 in. (191 mm) from the hazardous area, regardless of
the calculated safety distance.
Failure to comply with these instructions will result in death or serious injury.
