D) Adjusting the Closing Force and Speed
Open the door completely (max. opening 1.5 m) - there must re-main
min. 1.5 loops of rope on the spring rope pulley. The spring is tensioned
with the tensioning screw SW17 that is accessible from both sides. The
correct sense for the tensioning is indicated by the red arrows "Spannen"
(see ill. 5). Maximum pretension: depending on the type of the spring
rope pulley (see table below)!
Reducing the pretension: if the spring rope pulley has been tensioned
too much, the pretension can be reduced by turning the tensioning screw
against the direction of the arrows.
Force needed for tensioning/detensioning the spring:
25 N: about 12 Nm, 50 N: about 15 Nm, 80 N: about 17 Nm
