Example 2 with cegard/Lift LX: Bypassed light curtain in floor zone

This example shows another variant, illustrating how the cegard/Lift LX can be integrated in a system. The differ-
ence to example 1 is that the light curtain is bypassed somewhat earlier. The light curtain is thus overridden 10
cm prior to the flush position in the case of an elevator with a landing zone of ±10 cm. This variant is recom-
mended, as many elevator users try to open the door while travelling slowly. This connection does not trigger an
emergency stop under the conditions described, provided the elevator is already within the floor zone.
Important safety notice:
Mains power must also be available during a safety circuit interruption. Internal call signals (Innenrufe) must also
be supplied during a safety circuit interruption.
