Possible cause / solution
... the RolloTron Swivel Winder Standard DuoFern

Check the power supply incl. connecting cable and plug.
... the RolloTron Swivel Winder Standard DuoFern no
longer reacts at the configured switching time?
The end points may not be configured. Configure the end points,
see page 76.
... the roller shutters no longer stop at the configured
end points?
The end points may be displaced due to elongation of the belt. Re-
adjust the end points, see page 76.
... the roller shutters stop as soon as the operating
button is released?
The end points are not configured. Configure the end points, see
page 76.
... an automated function does not work?
The automatic function may not be configured or automatic func-
tions are not activated yet, see page 85.
... the RolloTron Swivel Winder Standard DuoFern
rotates in the wrong direction?
Possibly the belt is wrapped around the reel incorrectly, see
page 73.
... the roller shutters stop suddenly during upward
travel?
a) The drive may be jammed, for example, due to the roller shutters
freezing up or other obstacles.
b) The roller shutters may not be running sufficiently smoothly.
Check the roller shutters and roller shutter guides.
c) The roller shutters may be too heavy. The maximum tractive force
of the belt winder has been exceeded, see page 94.
