Setting the lower end position
1. Before the shutter curtain is joined to the barrel, press the DOWN switch to move the drive downwards until it shuts off
automatically.
2. Adjust the lower end position (Fig. 9) to position the barrel such that the shutter curtain can be easily secured to the barrel
or fi t the anti-lift devices in accordance with the manufacturer's specifi cations.
Setting the upper end position
Press the UP switch. The drive will retract the shutter. To increase or reduce shutter travel, adjust the corresponding setting
screw.
Note for roller shutter applications
When using anti-lift devices, closed bearings must be used. Use shutters which are suffi ciently stable,
for example made of aluminium, steel or wood. The shutter must run entirely along guide rails to prevent
it from being damaged.
Do not install any back squares or stoppers at the bottom rail to allow for changes to the length of the
roller shutter. The individual slats should be secured to prevent lateral shifting.
Ensure that the shutter runs smoothly and unhindered in both directions (UP and DOWN). This applies to
both initial and subsequent operation.
Function check
As a fi nal function check, let the shutter run in both directions to the end position. If an anti-lift device has been fi tted, check
that it is properly working in accordance with manufacturer's specifi cations. The anti-lift device must engage securely and
press the shutter down onto the window ledge, as well as pressing the top shutter slat fl ush against the roller shutter box.
Note
Becker tubular drives are designed for shorttime operation (S2/KB 4 min). A fi tted thermo protection
switch prevents overheating of the tubular drive. During commissioning (long roller shutter, or long
running time), triggering of the thermoswitch may occur. The drive is then switched off. After a short
coolingdown period, the system is ready for operation again.
The drive will only reach the full duty cycle when it has cooled down to ambient temperature. Avoid repea-
ted actuation of the thermo protection switch.
