POC Type 2 GuardShield Safe 2
|
Description
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.
|
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.” |
