The magnetic contacts in the switch are switched by a permanent magnet. The door control
assesses the switching status of the contacts independently of each other.
The “F1.7” fault indication appears if there is a fault.
Crash switch as NC or NO contact
The crash switch is activated if the door is pushed out of the guides.
If the switching contact is activated, the door is stopped, fault F4.5 is displayed, and a
changeover to "hold-to-run" is carried out. The door can be moved only via the integrated
push-buttons of the door control. Hold-to-run mode is only possible at crawling speed with
frequency inverter operation.
The fault "4.5" can only be reset in OPEN final limit position by pressing the STOP push-
button of the door control for more than 3 seconds or by switching the mains voltage off and
on. Fault "F4.5" will recur, if the switching contact continues to be activated.
