If an engine is shutdown by the over-speed protection system, the other engines' over-speed protection system will be what?

Explanation:
When one engine is shut down by its overspeed protection, the system for the remaining engines is designed to deactivate their overspeed protection. This prevents a cascade of trips from a single abnormal condition and allows the other engines to continue running while the fault is addressed. The protection isn’t kept active in this moment because that could cause unnecessary shutdowns of the other engines due to the same transient or disturbance. After the situation is resolved, protections can be restored as needed.
