23. What to do if... ?
Fault
... the roller shutter belt winder no longer reacts in the
morning at the configured switching time?
... the roller shutter belt winder does not precisely com-
ply with the switching times?
... the roller shutter belt winder fails to react properly
either manually or automatically?
Possible cause / solution
The electronic system switched off the drive after closing the roller
shutters because the deflection roller stopped turning. This is the case
if:
a) the [ Down ] key was pressed for an excessive period of time
during the configuration process for the lower end point. The
roller shutter slats are closed, but the belt continued to wind and
is no longer tight on the deflection roller.
b) The lower end point is displaced due to elongation of the belt.
The belt may never be slack.
Reconfigure the lower end point (see page 97) and ensure that
the belt remains tight to the deflection roller. In doing so, the
deflection roller must turn evenly.
It is possible that the random function is activated. Switch to automatic
mode [ AUTO ], see pages (17/18.)
a) The roller shutter belt winder is no longer ready for operation.
Carry out a software reset in accordance with the instructions on
page 103 and test the roller shutter belt winder using the default
factory settings.
