In the event of a power failure at the weather station, the controller can no longer control
the connected drives! If the full scope of functions is to be maintained even without the
mains power supply, an emergency power generator with corresponding changeover
from mains to emergency operation has to be installed on site.
Settings saved in the program of the controller are retained even in the event of a power
failure. When the mains power is restored, the controller is in automatic mode.
If the radio connection between the operating unit and weather station fails (e.g. due
to radio interference or empty batteries in the operating unit), manual intervention is no
longer possible. The controller remains in its present mode (manual or automatic).
Automatic mode continues to function as set until the radio connection is established
again, but cannot take account of the indoor temperature. The wind and rain alarm
functions are maintained even if the controller is in manual mode.
If cleaning or maintenance work has to be carried out in the vicinity of the awning(s)
or Venetian blind(s), the controller (weather station) must be isolated by switching off
the fuse installed on site and securing it to prevent restarting. This ensures that the
connected drives cannot start unintentionally.
If it starts to rain, it can take some time before the weather station detects rain, depending
on the intensity of the rain and the outdoor temperature.
Please also note, for example, that if it starts to rain during a power failure, an outdoor
awning is no longer retracted automatically if no emergency power generator is installed.
Please remember that the rails of sun shading systems installed on the outside of the
building can freeze. If the awning of Venetian blind is then moved, the sun shading
and drive may be damaged.
Please ensure that no-one is allowed to remain in the travel range of system parts
driven by the motor (risk of crushing!). The corresponding building regulations
must be observed.
