According to its intended use, the clamping unit DADL-EL-Q11-... provides
end-position locking of the semi-rotary drive aD.
Additional clamping components aJ can be ordered as supplementary lock-
ing cams for the semi-rotary drives with intermediate position DRRD-...-PS1.
2. General instructions
Warning
Danger of injury due to uncontrolled movement of components!
Mount or dismantle only in a pressureless status.
Observe the safety instructions in the operating instructions of the semi-
rotary drive.
Note that this product is inappropriate for use in safety-related sections of
control systems without additional measures conforming to statutory min-
imum requirements.
Information
For its own end-position sensing, the cylinder 1 has two T-slots for proximity
switches.

(
section 6).
18312d_5
Mounting variant B:
Mount the adapter plate 4
directly to the semi-rotary
drive aD with the screws 5
and centring sleeves 6.
Comply with the permissible
tightening torque
(
section 6).
18312d_6
Mount the cylinder 1 di-
rectly to the adapter
plate 4 with the screws 2
and centring sleeves 3.
Comply with the permissible
tightening torque
(
section 6).
3b. Mounting the flange 8
Position the semi-rotary drive aD in neutral position.
18312d_7
Orient the flange 8 so the
cut-out (A) for inserting the
clamping component aJ is
on the opposite side of the
cylinder 1.
Fasten the flange 8 with
the screws 7 and centring
sleeves 9.
Comply with the permissible
tightening torque
(
section 6).
3c. Mounting clamping component aJ
18312d_9
Fit a slot nut aC to each
cam aB with the screws aA.
18312d_10
Push the pre-assembled
clamping component aJ
through the cut-out (A) in
the circumferential groove
of the flange 8.
Use the same procedure for
the second clamping com-
ponent aJ.
4. Setting clamping component aJ
Position the semi-rotary drive aD into a desired end position.
18312d_11
Pull in the piston rod (B) of
the cylinder 1 by hand
(
section 5).
Alternative:
Connect the port (F) at the
cylinder 1 to the com-
pressed air and retract the
piston rod (
Warning in
section 2).
18312d_12
Place the clamping compo-
nent aJ in front of the piston
rod (B).
18312d_13
Let the piston rod (B) of the
cylinder 1 retract slowly in-
to the clamping compo-
nent aJ.
18312d_14
Position the clamping com-
ponent aJ so the piston
rod (B) is located in the
middle of cam aB.
18312d_15
Tighten the screws aA only
lightly at first.
Pull in the piston rod (B) of
the cylinder 1 by hand.
Twist the semi-rotary
drive aD until the screws aA
are freely accessible.
Tighten screws aA.
Comply with the permissible
tightening torque
(
section 6).
Make tubing connection to
the clamping unit at the
port (F).

5. Emergency release or manual retraction of the piston rod
In case of pressure failure or to adjust the clamping component aJ, the piston
rod (B) of the cylinder 1 can be manually retracted as follows:
18312d_17
Unscrew filter nipple (C).
Turn the screw (E) into the female thread (D).

7. In operation
Note
Avoid operative malfunctions and material damage!
Make sure that in the locked status the clamping unit is not impinged with
lateral forces from the semi-rotary drive aD:
–
Unlock DADL before the swivel motion is initiated into the other end posi-
tion
–
Do not use DADL as a holding device in the end positions. The occurrence
of lateral forces must be absorbed by pneumatic actuation on the end po-
sition of the semi-rotary drive aD that is travelled to.
Carry out the following steps after a pressureless, locked end position sta-
tus has been reached:
1.
Pressurize the semi-rotary drive aD in the direction of the end position.
2.
Pressurize the clamping unit at the connection (F).
Observe the process during operation as follows:
1.
Clamping unit unlocked.
2.
The semi-rotary drive aD runs to an end position.
3.
Clamping unit locked. Now the semi-rotary drive can become pressureless
and the end position stays locked.
4.
Clamping unit unlocked.
5.
The semi-rotary drive aD runs to the other end position.
8. Technical data
Information
Use of the clamping unit DADL-EL-Q11 and locking of both end positions
changes the minimum swivel angle of the semi-rotary drive aD as limited by
the width of cam aB.
