Presence Sensing Safety Devices Safety Light Curtains GuardShield Type 4 Specifications Description The Allen-Bradley Guardmaster GuardShield safety light curtain is an economical, fully featured, Type 4 safety light curtain in a uniquely styled housing. GuardShield safety light curtains are general purpose presence sensing devices designed for use on hazardous machinery providing point of operation, as well as perimeter and access guarding. This self-contained, two box, safety light curtain has DIP switch selectable operating modes and are available in both 14mm and 30mm resolutions. Modes of operation such as fixed and floating blanking, beam coding, start/restart interlock, external device monitoring (EDM), machine test signal, are selected by dip-switches settings. These dipswitches are located beneath a security door, which are conveniently located on both the transmitter and receiver end caps.
