Possible cause / solution
a) The roller shutters may have hit an obstacle.
Move the roller shutters back up and remove the obstacle.
b) Slats have shifted out of alignment.
If possible, move the roller shutters back up and realign the slats.
c) The roller shutters scrape against the window frame inside the roller
shutter box due to the lack of a pinch roller or insulation material
may have come free and is jamming the roller shutters.
Open the roller shutter box and rectify the fault. Lubricate any stiff
areas with gliding wax if necessary.
d) The roller shutters are too light.
Increase the weight of the roller shutters by, for example, adding
a piece of flat steel to the bottom slat.
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.
