Light curtain safety distance

This post explains how to calculate . This distance , referred to as the safety distance , must be properly calculated prior to determining the safety light curtain protective height and mounting the light curtains on the machine. Failure to properly calculate this safety distance may result in operator injury. The following formula is used to compute the minimum safety distance (Ds) on mechanical power presses to meet the ANSI (American National Standards Institute) B11.

At Sick, we have observed this on countless occasions during initial safety inspections.

There was some concern raised about the gap, and whether or not additional guarding might be needed to close .

Ts = Stop Time (in milliseconds). Solution: Use the OSHA or ANSI formula to calculate the correct safe - ty distance (see sidebar). Re-install the light curtains at the correct safety distance , or farther, from the nearest pinch point.

Formula for calculating safety distance of light curtains from hazardous point of operation. The protection zone must be configured so as to ensure the safety distance , which has been calculated according to the laws, regulations, and standards of the country or region in which the laser scanner (SZ) is installed as well as according to the specifications given in this document. These values differ depending on the Switch.

Refer to the “Precautions for Correct Use” for the Switch you are using. It might be necessary to resort to additional safety devices (i.e.: photoelectric light curtains arranged horizontally). ISO (International Organization for Standardization). A Leuze electronic USA webinar series focused on the technical aspects of machine safety that allows the participant to better understand the recognition of.

The following is Wintriss Controls and Production Resources recommendations for establishing safety distance with the use of blanking functions: Three types of blanking systems exist and vary depending on the Shadow light curtain . The factory did not have that much space, nor was it realistic. Instea the solution became vertical sliding safety barriers. When installing safety light curtains , a minimum safe distance that the light curtain can be mounted from the point of hazard must be calculated. Use of the laser pointer allows simple alignment of the beams especially across long distances. This saves approximately of installation time.

Safety Laser Scanner SZ Series. They also minimize operator resistance to these types of safety devices due to their nonrestrictive design. Presence sensing devices are commonly referred to as light curtains.

There are many requirements that must be met before light curtains can be installed as point-of-operation safeguards. Also, safety devices such as light curtains are often installed too close to the hazard point where residual danger still .
