5.1 Adjustment of the intermediate position
Note
Without counter pressure, the connection between the sleeve and the screw-in
connector inside the intermediate-position module can loosen. This can result in
failure to function.
• Turn the lock nut or dampener only with simultaneous counter pressure on the
spanner flat of the sleeve
9
.
• Check the setting dimension of the two dampeners
1
:
– setting dimension X1 and X2 are the same size
(dimension Y = 0
Fig. 5, delivery status)
– setting dimension lies between X
min
and X
max
(
Fig. 6).
• If necessary, adjust the intermediate position as follows:
1. Loosen the lock nuts on both dampeners
1
.
2. Turn the dampener
1
until the desired intermediate position is reached. When
doing this, hold the sleeve
9
. The setting dimension must lie between X
min
and
X
max
(
Fig. 6).

3. Press the dampeners into the travelled-in end position until they meet resist-
ance. The shaft of the semi-rotary drive thereby rotates into the intermediate
position.
Through the off-set mounting of the shock absorber (dimension Y), the mid-pos-
ition (W=90°) can be adjusted by ±10°.
The following settings are possible (
Fig. 5 and Fig. 6).
Fig. 5
If the setting dimension Xmax is exceeded, the shock absorber does not cushion
correctly at the intermediate position.
If the setting dimension Xmin is fallen below, the shock absorber not only cush-
ions the intermediate position, but also the end position of the semi-rotary
drive. The cushioning time of the end position might rise as a result. The cush-
ioning time of the intermediate position is not affected by this.

Note
Without counter pressure, the connection between the sleeve and the screw-in
connector inside the intermediate-position module can loosen. This can result in
failure to function.
• Tighten the locking nuts again. Tightening torque (

To lock the hex nuts, the spanner flat of the sleeve or the internal hexagon
socket of the dampener must be counter held.

5.2 Setting of the swivel speed
Note
• Observe the following relationship when setting the swivel speed:
– The flow control valves at the connections for rotation of the semi-rotary
drive affect the speed with which the intermediate position is travelled to.
Both directions can be adjusted separately from each other.
– The flow control valve at the connection for the intermediate position regu-
lates the speed with which the end position (from out of the intermediate
position) is travelled to. Both directions are hereby regulated simultan-
eously.
