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 difference
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 recommended, 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.
SAFETY ADVICE
Mains power must also be available during a safety circuit interruption. Internal call signals (Innenrufe) must
also be possible during a safety circuit interruption.
