Abstract
An industrial robot safety device and method for use in wet stations. A shutdown circuit is operative to deactivate the robot in response to operation of any one of two switches. Each switch responds to variations in tension that are beyond acceptable limits of an associated tensionable element, such as ropes or cables. The tensionable elements are respectively mounted on the left and right side of the robot in the paths of its travel.
