Features

ATTENTION: Safety light curtains of a Type 2 level of

safety typically do not meet OSHA or ANSI requirements

of “Control Reliability,” therefore it is not allowable to use

a safety device of a Type 2 level on or around equipment

or machinery that requires “Control Reliability.”

y Conveyors

y Textile machinery

y Automatic storage and retrieval machinery

y Automated assembly lines

The Allen-Bradley Guardmaster GuardShield Safe 2 safety light

curtain is a new addition to the ABGM portfolio of opto-electronic

safety devices. The “Type 2” designation means that this particular

safety light curtain meets a lesser requirement for performance

under fault conditions than the GuardShield Type 4 safety light

curtains. As a result, the GuardShield Type 2 safety light curtain can

only be applied in applications where a formal risk assessment has

determined that a Type 2 device is sufficient to meet the level of risk

posed by the hazard.

The GuardShield Safe 2 safety light curtain is a self-contained two-

box, safety light curtain in a robust housing with an integrated laser

alignment system. The integrated laser alignment system generates

two visible beams of light which simplifies alignment of the light

curtain pair.

This economical opto-electronic Type 2 safety light curtain is offered

in a guard only mode of operation and is designed for use on or

around machinery or equipment where a formal risk assessment has

determined that a Type 2 safety device is of a sufficient level of

safety to meet the guarding application.
