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.

3. Mounting
3a. Mounting the cylinder 1

 Select the desired position of the cylinder 1. It is mountable on the semi-

rotary drive from the left or from the right.

18312d_4

Mounting variant A:
 Mount the cylinder 1 di-

rectly to the semi-rotary
drive aD with the screws 2
and centring sleeves 3.

 Comply with the permissible

tightening torque
(

 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:

Pressurize the semi-rotary drive aD in the direction of the end position.

Pressurize the clamping unit at the connection (F).

 Observe the process during operation as follows:
1.

Clamping unit unlocked.

The semi-rotary drive aD runs to an end position.

Clamping unit locked. Now the semi-rotary drive can become pressureless

and the end position stays locked.

Clamping unit unlocked.

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.
