Product Manual
Access guarding protects people who are required to occasionally access a danger zone. In the figure below, the vertical PF of the AG4 is used
to detect a person who walks into the cell. A side post and the floor serve as reference surfaces for monitoring the boundary of the PF. In
contrast to danger zone guarding, the AG4 no longer detects a person in the cell after they pass through the PF. This is why the start/restart
interlock function is vital for access guarding.
