MODE
Soft run setting for drives with
S12
The drive has an electronic position detection. Just before
the CLOSED position the chain retracts with reduced speed
in the soft run mode, to protect the window and the drive.
• In soft run mode the zero-point - and thus the CLOSE-
postion of the window - is recognized.
• The drives with
S12
must turn off in the soft run range
(about 40 mm in front of the CLOSE-position).
• In closing direction in case of overload outside the
40 mm soft run range, the chain moves out by ap-
proximately 10 mm.

Operation of the power-operated window
When operating the power-operated window safety
instructions must be observed, specifi cally those pertaining
to commissioning, operation and maintenance.
Check the mounted system for its safety; perform test run
and commissioning.
Safety test:
• Connect operating voltage.
• Check fastening (frame brackets, casement brackets)
for fi rm fi t or tightening.
Test run:
• Visual inspection of casement movements.
• Stop immediately by malfunction!
• Pay attention to collision with facade construction and
correct installation, if required.
Risk evaluation:
Before operating a power-operated window to which
window drives were mounted, which were sold by the
manufacturer as incomplete machines according to instal-
lation declaration, the possible risk to ahazard of persons
must be determined, evaluated and minimized by taking
appropriate technical measures in accordance with the Ma-
chinery Directive. Separate documents for performing a risk
assessment can be downloaded from the homepage of

Formula to calculate
the required wire cross-section of a supply line
Calculation example
Available data:
• cut-off current per drive (i. e. 2 x 4.0A) from data sheet
• length to be bridged from the last window to the control unit
(i. e. 10 meters)

ECOMMENDATION
Observe current regulations and guidelines e.g. DIN 4102-
12 regarding the “Fire behavior of building materials-
circuit integrity maintenance of electric cable systems“
(E30, E60, E90) and the “Specimen Guideline on Conduits
German designation - MLAR“, and also prescribed construc-
tional regulations!
For safety reasons a cable of the next hig-
her wire cross section should be selected.

Laying and connecting the drive cable
• Avoid extreme temperature differences in the instal-
lation area (danger of condensation).
• Set clamping point close to window and ensure
accessibility.
• Ensure expansion possibilities of the drive and the drive
cable.
• Consider the cable length of drives.
