Obstruction detection / Blockage detection
Caution
Use of the drive’s obstacle detection system as personal protection is not permitted. It has
been designed exclusively to protect the roller shutters or sun protection system from be-
ing damaged.
If the drive is correctly installed, it switches off when it detects obstructions or shutter faults.
The following are detected both when using attachment springs and when using anti-lifting devices:
In the DOWN direction (Obstruction detection)
A curtain jam when closing due to objects on the window sill or sticking of the lateral guide tracks.
In the UP direction (Blockage detection)
Extremely large increase in the load (e.g., frozen end strip on the window sill)
To avoid overly sudden deactivation during closing, the drive only responds to an obstruction one or two revolutions after the im-
pact.
