What feature may override door protective devices and enable door closing despite an obstruction?

Nudging is a feature that allows the elevator doors to close even when an obstruction is detected, essentially overriding the protective devices that are intended to prevent the doors from closing onto an object or person. This function is typically utilized in situations where the elevator is expected to operate with minimal interference, such as during low-traffic periods when quick door closures are necessary for efficiency.

Nudging works by allowing a brief, controlled application of force to the doors, encouraging them to close while momentarily disregarding the typical safety features that prevent closing when something is in the way. This can be beneficial for operational purposes but needs to be used with caution to ensure safety is not compromised.

In contrast, manual push would still respect the protective devices, requiring the obstruction to be cleared for the doors to close. Assisted closing may refer to smoother door operations but does not necessarily bypass safety mechanisms. Override mode usually involves a different set of operational parameters or controls that might also respect safety features but isn't specifically designed to address obstructions like nudging is.
