Phase 1

The emergency-close mode is activated after 0.5 s when the position "one-touch closed" is held. The window is closed at maximum speed and with modified anti-trapping protection. Releasing the button terminates emergency closing, (i.e. the window proceeds to be closed with full anti-trapping protection as with automatic operation).

Anti-trapping protection remains activated in modified form even during emergency closing. If trapping is detected, the window travels back only the short distance of 20 mm. This relieves strain on the mechanical system or gives the attacker the option of backing away.
