When the curtain jumps out of a guide the shutter is no longer supported the way it was designed to be. Every further press of the button bends more slats and risks the whole curtain coming down.
Why It Happens
A curtain leaves the guides because something else has already failed — a worn end lock, a spread or impacted guide rail, a snapped spring letting the curtain drop unevenly, or a strike from a vehicle.
Simply pushing it back in without finding that cause means it will happen again, usually within weeks and usually with more damage the second time.
The commonest cause — end locks worn past the point of holding the slat in the guide.
Spread, dented or twisted guide rails straightened or replaced.
A failed counterbalance letting the curtain drop unevenly and skip out.
Vehicle and forklift strikes that knock the curtain and rail out of line.

The Repair
Re-track the curtain, replace what let it out, and check the barrel and springs before you use it again.
The opening secured and the curtain supported so nothing drops while a permanent repair is arranged.
Curtain fed back into the guides with worn end locks replaced, so it holds this time.
Damaged rails straightened or renewed, barrel run-out and spring tension checked at the same visit.
Don't try to run it back up. Ring the emergency line and keep people clear of the opening until an engineer has supported it.
