These settings are only possible if the plug-in sensor for
the safety edges is fitted.
Pneumatic safety edges are tested for safety-related
reasons during every downward movement. This proc‐
ess is called testing.

Safety edge with 1k2 Ohm terminating resistor with testing
The safety edge is tested during every closing movement: Once the
pre-limit switch is activated, the safety edge must be activated within 2
seconds (positive testing)
