The Banner AG4 Safety Laser Scanner is placed at the base of the hazardous area and “looks out” at the open area. It is programmed via a PC with interface software to guard the area between the physical barriers (the protective zone) and outside the barriers (the warning zone). If the operator or other personnel approach the hazardous area during robot operation, a signal is sent to alert the person that the warning zone has been entered; the robot continues operation during this time.
Safety laser scanners work well for safeguarding applications where user access and protection are equally important. Banner’s AG4 Safety Laser Scanner with a 190º scanning angle fits nearly any shape and can evaluate an operator’s position by range and rotational angle. Its flexibility allows for new safeguarding shapes when work cell dimensions and parameters change.
