E) Adjustment of the Closing Force and Speed
Open the door completely (max. opening 1.5 m). There have to be
left at least 1.5 windings of rope on the spring rope pulley.
The spring is pretensioned by the tensioning screw SW 17 that is ac-
cessible from both sides in the direction of the arrows "spannen" =
tensioning (ill. 14a - 14c). Maximum pretension: 2, 4 respectively 5
revolutions depending on the used spring rope pulley (see table below)!
Releasing: in case the spring had been tensioned too much, the preten-
sion can again be reduced by turning the tensioning screw against the
direction of the arrow.
