Light curtains should be function-tested at every setup, operator, 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 checklist has the light curtain function-testing procedures on the front; the back contains the ANSI B11.19-2003 safety-distance equation and other information needed to calculate the safety distance for light curtains.
