Assembly and Operating Instructions
All.P5/16PRF+A1,.P9/16PRF+A1,.R8/17PRF+A1.to.R40/17PRF+A1.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.
Other.applications,.utilisation.and.modifications.are.not.permitted.in.order.to.protect.the.safety.of.the.users.and.others,.since.
these. actions. can. impair. the. system’s. safety,. resulting. in. personal. injuries. and. property. damage.. Becker-Antriebe. shall. not.
accept.liability.for.damages.arising.from.such.actions..Always.observe.the.information.in.these.instructions.when.operating.or.
repairing.the.system..Becker-Antriebe.shall.not.accept.liability.for.damages.resulting.from.incorrect.usage.
Attention
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.
Example:
60-series.octagonal.tube.with.anti-lifting.device.from.Zurfluh-Feller:
Effective.tube.diameter:.9.cm.->.min..window.height.>.45.cm
Mounting the roller shutter drive
Attention
Drives from Becker Antriebe are to be mounted and operated
solely with mechanical accessory components shown in the
current Becker product catalogue.
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 direc-
tion 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 recommend fitting covered stoppers into
the guide rails prior to mounting.
1.. The.lateral.spatial.requirements.(M).for.the.box.end,.the.counter.bearing.
and.the.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.
Attention
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.
