Intended use
The type of tubular drive described in these instructions is intended solely for the operation of sun protection systems with locking
systems . To function properly, these tubular drives need a fixed stop in the upper limit position (retracted blind).
It may only be used in networked systems if all the individual drives are exactly synchronised and reach the upper limit position at
the same time.
For roller shutter applications, please use only the types of tubular drive designed for this purpose.
This type of tubular drive is designed for use in single systems (one drive per barrel).
The tubular drive must not be used in potentially explosive areas.
The connecting cable is not suitable for transporting the drive. Always carry the drive by the housing tube.
Other applications, uses and modifications are not permitted in order to protect the safety of the users and others, since these ac-
tions can impair the system’s safety and carry the risk of personal injury and property damage. The drive manufacturer does not
accept liability for damages or injury arising from such actions.
Always observe the information in these instructions when operating or repairing the system. The drive manufacturer does not ac-
cept liability for damage or injury resulting from improper usage.
Assembling and disassembling the plug-in connecting cable
Assembling the plug-in connecting cable
Insert the dead connecting cable into the drive head until the locating lug clicks into place in the drive. If necessary, use a suitable
flathead screwdriver to assist with insertion. Set the screwdriver into one of the two plug grooves provided for this purpose.
Check that the cable is properly engaged.

Installation
Assembling the drive
Attention
To connect the drive to the driven part, solely mechanical accessory components made by
the drive manufacturer from the current product catalogue may be used.
Prior to mounting, the fitter must ensure that the masonry and the system being motorised are sufficiently robust (drive torque plus
weight of the shading solution).
Caution
Electrical connections may only be carried out by a qualified electrician. Prior to assembly,
the power supply must be disconnected and secured. Please give the enclosed connection
information to the responsible electrical contractor.
Calculate the space required at the side (M) by measuring the drive head (1) and wall
bracket (2). The clear dimension of the box (X) minus the space required at the side
(M) and idler (G) gives the length (L) of the barrel: L=X-M-G.
The space required at the side (M) varies depending on the combination of drive and
wall bracket.
Then mount the wall bracket and idler. Ensure that the barrel is aligned at right angles to the wall and that sufficient axial play is al-
lowed for the mounted system.
Undoing the mounting pin
When pushed in, the mounting pin (2) locks automatically. To undo the mounting pin
(2), push the tab washer (1) upwards and pull out the mounting pin (2).

Mounting the drive in the tube
For profile tubes:
In the case of some drive adapters, tolerances of the groove widths in different bar-
rels can be offset by rotating the drive adapter into a different groove recess. These
groove recesses have different sizes and allow the drive to fit exactly.

For round shafts:
Measure the lug of the thrust ring (X, Y). Then notch the tube on the motor side, so
the lug of the thrust ring can also be pushed into the shaft. There must be no play
between the lug of the thrust ring and the shaft.
-10 mm
To ensure secure torque transmission for round shafts, we recommend screwing the
drive adapter to the shaft (see the table below).

lar drive. During commissioning (long drop distance or long running time), the ther-
moswitch may trigger. The drive will switch off. After a short cooling-down period, the sys-
tem is ready for operation again.
The drive does not achieve its full duty cycle until it has cooled to ambient temperature.
Avoid a situation where the thermal protection switch cuts in repeatedly.
The limit positions can only be set with the master transmitter. The shutter direction must
be correct. When setting the limit positions, the tubular drives runs in dead-man mode. If
the tubular drive switches off prematurely while opening, due to an obstruction, the ob-
struction can be cleared by closing the screen and removing the obstruction. The upper
limit position can be set by opening again.
