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.”

The Allen-Bradley Guardmaster GuardShield Safe 2 safety light
curtain is a new addition to the Allen-Bradley Guardmaster 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.
