Stationary access guarding
Stationary access guarding protects people that step into a danger zone. The vertically aligned protective
field of the safety sensor detects the passage of a person. A side post and the floor serve as reference
contour for monitoring the position of the protective field. In contrast to danger zone guarding, the safety
sensor no longer registers a person in the danger zone after the passage. This is why the

function is vital for access guarding.

Mobile danger zone guarding
Mobile danger zone guarding protects people that are located in the transportation path of a driverless
transportation system (DTS). The distance between the protective field front edge and the vehicle front
must be greater than the stopping distance of the vehicle with selected speed and maximum load. A safe
control system selects speed-dependent protective fields and can activate side horizontal protective fields
for curved stretches.
