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 hazard (see Figure 6-23). The
“pinch point” is the area of the press where moving parts can cause injury.
If you have not installed light curtains and are using a Two-hand Control as a safety device,
you must mount the Two-hand Control at least the safety distance from the pinch point.
PRESS MAY NOT STOP BEFORE OPERATOR REACHES PINCH POINT
• Calculate the safety distance according to the applicable safety regulations, the instructions in
this chapter and in your light curtain user manual.
• Mount the Shadow light curtain heads at least the safety distance from the nearest pinch point
or hazardous area of your press (see Figure 6-23).
• Mount your Two-hand Control at least the safety distance from the nearest pinch point or
hazardous area of your press if you are using the Two-hand Control as a safety device.
• Mount your light curtain heads at least 7.5 in. (191 mm) from the nearest pinch point hazard,
even if that is greater than the safety distance you calculate.
Failure to comply with these instructions will result in death or serious injury.
