... the RolloTron Comfort indicates no functions? Check the power supply incl. connecting cable and plug.
... the RolloTron Comfort no longer reacts in the morning
at the congured switching time?
The electronic system switched o the drive after closing the roller
shutters because the deection roller stopped turning. This is the case if:
a) The [ Down ] button was pressed for an excessive period of time
during the conguration 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 deection roller.
b) The lower end point is displaced due to elongation of the belt.
The belt may never be slack.
Recongure the lower end point (see page 50) and ensure that
the belt remains tight to the deection roller. In doing so, the
deection roller must turn evenly.
... the roller shutters no longer stop at the congured
end points?
The end points may be displaced due to elongation of the belt. Re-
adjust the end points, see page 50.
... the roller shutters stop as soon as the control key is
released?
The end points are not congured. Congure the end points, see
page 50.
... the RolloTron rotates in the wrong direction? Possibly the belt is wrapped around the reel incorrectly, see page 18.
