What feature allows a system to run in an emergency without stopping?

The feature that enables a system to operate in an emergency without stopping is known as emergency run. This capability is crucial in various applications where maintaining operational continuity is essential, especially in critical systems like industrial machinery or automated processes. An emergency run allows the system to continue functioning, often at a reduced capacity or with some restrictions, to prevent catastrophic failures or to ensure safety until normal conditions can be restored.

This feature is particularly relevant in scenarios where an immediate shutdown could lead to hazards, such as equipment damage, safety risks, or production line disruptions. By having the ability to activate an emergency run, operators can take necessary actions to either stabilize the system or safely shut it down while mitigating potential dangers.
