Fabric Stretching Function (Awning)
Fabric material can be used with some awning mechanisms. This type of mechanisms may be damaged
when reached the lower end position because of over stretch. The fabric-stretching function permits
stretching the fabric of an awning tight after lowering. The fab-ric-stretching function can also be used
with shutters to re-open the slits of the shutter curtain after a downward movement into the lower end
position. If activated in the ETS parameters, fabric stretching is executed during each downward travel
after stopping. The curtain is then 'stretched' by moving it briefly in the opposite travel direction.
Fabric-stretching is never effected in upward travel movements.

Central Up/Down Control Function
The blind or shutter updown controlling can be realized with central up/down function. The important
point here is every blind or shutter channel must be participated in central up/down function by
“Participation in central up/down object” parameter. Central up/down object is used for up/down
control of blind/shutter. The basic mission is the same as the up/down object. If “0” is sent to this
object the participated blinds travel for upward direction and if “1” is sent to this object, the
participated blinds travel for downward direction.
4.2.3.9
Scene Function
There are 8 scene parameters for one blind/shutter channel. Each of 8-scenes are called by the
selected scene number from 1 to 64. The Blind position parameter specifies the height level of blind
when the related scene is called. ( After installed from ETS, the behaviour for scene number can be
changed if the Permit teach in parameter is “YES”). The Permit teach in parameter specifies whether
the related scene can be saved or not when the save scene command is called.
