GEZE E740 Syncro System- Und Montageanleitung Seite 33

IMPOR- Connection of the control lines (RED and WHITE) has to be carried out completely before the
TANT: first movement of the drives with a completely retracted chain. Otherwise communication
problems may occur between the two drives.
If the power connection cable of this device is damaged, it has to be replaced by a special connection
cable that can be obtained from the manufacturer or the customer service.
The drives function in Syncro operation mode only with 2 to 4 drives.
The drive can also be operated individually for adjustment during assembly. For this purpose the power
supply has to be connected (consider open/close direction!) and the control lines (RED and WHITE) have
to be disconnected.
The single mode is only defined for the individual drive being activated. Before activation, make sure
that the window or the other drives will not be damaged by the motion of the drive.
To activate the single mode first set the stroke adjusting knob to "1", then immediately to the position "4",
back to "1" and then set the desired stroke. This procedure must be completed within 5 sec time. The drive
can now be operated once in the desired direction. Repeat the procedure for a further stroke movement.
