Run the test 5 more times. Record the highest reading from all your tests to use as the
Stop-time value in calculating the safety distance.
Calculating the Safety Distance
The “safety distance,” as shown in Figure 3-9, page 3-20, is the distance from the pinch point
(or hazardous area) of the press that Shadow light curtains must be mounted to allow enough
time for Shadow to react, and the press to stop, before the operator can penetrate the light
curtain and reach the hazard. 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.
The safety distance is calculated using a formula that incorporates the Stopping Time of your
press as determined by the 90° stop-time test (see Determining the 90° Stop Time, page 3-17).
You must mount your light curtains slightly beyond this calculated distance to ensure that they
are able to stop the press before an operator’s hand reaches the hazardous area.
The first time you run this test, the display shows a value of “0” (zero) until the test is
completed. In subsequent tests, the display shows the Stopping Time measured in the
last test.
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 3-9, page 3-20).
• 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 1/2 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.
