D) Adjusting the Closing Force and Speed
Open the door completely (max. opening 1.5 m) - there must remain
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. 6a - 6c). Maximum pretension: depending
on the type of the spring rope pulley 2, 4 or 5 turns (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/releasing the spring:
25 N spring: ca. 12 Nm, 50 N: ca. 15 Nm, 80 N: ca. 17 Nm
25 N
