Function-Testing Checklist for Light Curtains (LLL055)
Light curtains should be function-tested often using the function-testing checklist at every setup, operator change, and shift change, as well as every time after maintenance is performed. This light curtain function-testing checklist can be used for this. It is laminated and has a grommet in the corner so it can be kept at the machine.
The function-testing checklist has procedures on the front; the back of the function-testing checklist contains the ANSI B11.19-2003 safety-distance equation and other information needed to calculate the safety distance for light curtains.
