Intended Use - Becker R8/17PFR+ Notice D'utilisation

All Rxx/17PRF+ tubular drives are intended solely for the operation of roller shutters. The tubular drive is fitted with springs which support both
the shutter suspension and mechanical anti-lifting devices (e.g. Zurfluh-Feller, Simu, GAH Alberts or Deprat). These are detected automatically.
Any other use or use outwith the intended use stipulated is considered improper.
If the controls and drives are used for any purpose other than that specified above or if modifications are made to the equipment which affect
the safety of the system, the manufacturer or supplier will not accept any liability for any injuries or damage caused to persons or property, nor
for consequential damage arising as a result thereof.
These operating instructions must be adhered to for system operation or repair. In the event of improper handing, the manufacturer or supplier
will not accept any liability for any injuries or damage caused to persons or property, nor for consequential damage arising as a result thereof.
Anti-lifting devices in the form of axle shaft locks which are mounted between the roller tube and shutters in place of springs are automatically
detected by the tubular drive during installation.
Warning
Anti-lifting devices may only be used if sufficiently rigid roller shutter laths made of aluminium, steel or wood are used.
When closed, the shutters must not extend over the guide rails, as this may put too great a load on the joint between the top
two slats, which could consequently be damaged.
Before reaching the lower end limit, the roller shutters must have made at least 1.5 revolutions. This is normally the case when the window
height is five times the effective tube diameter.

Mounting and installation instructions
Mounting the roller shutter drive
1. The lateral spatial requirements (M) for the box end, the counter bearing and the
G
motor bearing must be determined in order to calculate the required length of the
roller tube. The length (L) of the roller tube is equal to the clear dimensions of the
roller shutter box (X) minus the total length of the wall bracket, box end (M) and
counter bearing (G): L=X-(G+M).
Measure the distance from the wall bracket and connecting head as this may vary
depending on the drive and bearings used.
2. Secure the wall bracket and the counter bearing.
Note
Prior to mounting, the fitter must ensure that the masonry and the
shutter box are sufficiently robust (drive torque plus weight of the
shutters).
Caution!
These drives may not be operated with conventional switching elements
(switches, timers or similar).
If the roller shutters are to be operated in the opposite direction to the
upper stopper, the shutters must be stopped from being wound up into
the shutter box by stoppers or by a right-angled end slat. We recom-
mend fitting covered stoppers into the guide rails prior to mounting.
Warning
If anti-lifting devices are being used, closed bearings must be used.
When the shutters are closed, the tubular drive pushes the shutters
downwards to prevent them from being raised or forced open. Always
use suitably robust shutters, for example made of aluminium, steel or
wooden. To prevent the shutters from being damaged the entire shutter
must run in guide rails.
