Upper Anti-Freeze Mechanism; Activating/Deactivating Upper Anti-Freeze Mechanism; Obstacle Detection - Becker C01a Assembly And Operating Instructions Manual

Roller shutter drive with integrated radio receiver 915.3 mhz

Table of Contents

The upper anti-freeze mechanism helps to prevent the roller shutter from freezing in the upper limit position, as the roller shutter

stops just before the upper stop. The distance from the upper stop is automatically cyclically checked and, if necessary, correc-

ted.

The upper anti-freeze mechanism is deactivated on delivery.

Both limit positions must be set before the anti-freeze mechanism can be activated.

The anti-freeze mechanism only works if a permanent stop is set at the upper limit position

of the roller shutter. The anti-freeze mechanism is not visible until the shading solution has

reached the upper stop from the lower limit position 3 times in succession.

Activating/Deactivating upper anti-freeze mechanism

Caution

Obstacle detection is only active in conjunction with the "drive adapter for obstacle detec-

tion".

In addition, please note that the drive must be pushed in to the shaft as far as the band of

the thrust ring.

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 and reverses a short way in the oppos-

ite direction and thus away from the obstacle.

If reversing is interrupted, a further drive command is only possible in the direction of reversing. Travel the shading solution without

interruption until the tubular drive stops automatically. It is now possible to travel in both directions again.

The following are detected:

Moving DOWN

• A curtain jam when closing due to objects on the window sill or sticking of the lateral guide tracks.

If the tubular drive switches off in the area of the upper limit position, it checks once more

whether an obstacle is present.

To ensure complete closing of the roller shutter curtain at the lower limit position, the curtain does not reverse once it gets to ap-

prox. 360° from the lower limit position.

Moving UP

• Extremely large increase in the load (e.g., ice on the end strip)

To ensure that the roller shutter curtain safely enters the guide tracks, obstacle detection is inactive for approx. 1.5 revolutions of

the barrel from the upper limit position.
