°
Stop-time Test
The 90
°
stop-time test is required by OSHA regulation 1910.217 and ANSI standard
B11.1-2009 to set the proper safety distance for personnel-guarding devices including light
curtains, two-hand controls, and type-B movable barriers. This test is performed at the press’s
most critical stopping point–90
°
. Follow these steps to perform the 90
°
stop-time test:
1.
Install the heaviest upper die you use on your press. Adjust the counterbalance for ram
weight, if your press has a counterbalance.
2.
With the Program/Run key set to RUN, select BRAKE MONITOR on the Main Run
Menu. The Stop Time Status screen displays.

Run the press in Continuous mode. If the press has a variable speed drive, set press speed
to the highest value you will normally use.

Press the Up (
) cursor key to start the 90
°
stop-time test. The following message
displays at the bottom of the screen:
90 DEGREE BRAKE TEST ARMED

reaches 90
°
, record the STOP TIME value displayed on the Stop Time Status screen.

Repeat the test at least 5 more times.

Record the highest reading from all your tests. This is the value you should use in
calculating the safety distance.
