8 Mounting the device
ATTENTION
Risk of inappropriate assembly
The device must be assembled by trained and qualified persons only.



After mounting the hardware, make sure it is working correctly.



Carefully follow the enclosed installation drawings.
DANGER
Risk of crushing
During the automatic opening and closing of the window, push and pull
forces of up to 300 N occur. These forces are capable of crushing limbs
should you reach into the area between the sash and the frame. In
particular because in the event of a jam the motor will attempt repeatedly
to complete travel.



Keep children, disabled persons, and animals away from the window.



Do not reach between sash and frame when the motor is running.



In the case of a window sash installed below 2.50 m, secure
all crushing and shearing points to ensure that persons do not
accidentally reach into them. Observe VFF code of practise KB.01:
Power-Operated Windows.
DANGER
Risk of injury
Motor-driven Tilt-Only windows must always be equipped with a safety
catch to prevent injury caused by falling sashes.
Furthermore, there is a risk of injury when assembling the motor on a
window that has already been installed if the sash opens suddenly.



Always use appropriate safety devices such as security stays to catch
the window.



The safety stay must be adapted to the opening width of the drive. To
avoid jamming, the opening width of the safety stay must exceed that
of the drive.



Install the motor in a way that it is always accessible.



Follow the installation drawing. This is enclosed in the fixing set or can be obtained
from your nearest subsidiary and contains the dimensions for the various installation
methods and profile systems.



All dimensions of the particular installation are the responsibility of the installer;
adjustments may be necessary.



Before working on the profiles, take note of the following:
 Minimum sash width
 Minimum sash height
 Maximum sash weight
 Possible wind and snow loads
 Space required on the profile according to the assembly method.



Check the required minimum distances.



Perform a function check. For this purpose, use the proper GU testing and setting
apparatus (see section "11 Components and accessories" on page 14).

Switching off in the closed position
The drive switches off via the integrated load cut-off in the closed position. The limit switches
therefore do not need to be adjusted. When the end position is reached, the drive reverses
approx. 1 mm. This relieves the load on the gaskets as well as the fastening brackets.
Setting the travel
The travel of the chain drive is set at the factory to 400 mm.
The travel can be changed at any time via the DIP switches. These are under the cover. Only
the settings of DIP switches 1 and 2 have to be changed as indicated in the table below. To
apply the change, the chain must be extended slightly then retracted.
After this a test run should be completed.

Handheld radio transmitter
The ELTRAL KS 30/40 RADIO CONTROL chain drive is operated exclusively using the
KS 30/40 handheld radio transmitter (Order No. K-19046-00-0-0). It cannot be operated using
handheld transmitters by other manufacturers.
For more details on the characteristics and functional principle, please refer to the operating
instructions enclosed with the handheld radio transmitter. Read the operating instructions for
the handheld radio transmitter first, and observe the directions given. The transmitter is not
programmed at the factory.
The radio transmission frequency is 433.92 mHz and has a variable code ("Rollcode") with 16
billion possible combinations. The code changes with every transmission operation according to
an algorithm that conceals the code used thus ensuring an optimum degree of security.
Several drives can be controlled via the handheld radio transmitter, in which case every channel
must be assigned to an ELTRAL KS30/40 RADIO CONTROL drive and therefore a window.
The handheld radio transmitter has 30 channels which means that up to 30 windows can be
controlled individually. A maximum of 15 handheld radio transmitters can be stored on every drive.
Several channels can be combined into a group so that several drives can be activated
simultaneously at the push of a button. A maximum of 2 groups each containing 10 channels
can be programmed.
Special applications, such as an automatic ventilation function, can be programmed at the
factory via function buttons. These function buttons cannot be programmed individually by the
user.
