3Replacing the electronic knob
3.1 Relates to the following variants
CX6162/66
CX2162/66
3.2 Necessity of the measure
The electronic knob is faulty and has to be replaced.
3.3 Procedure
If the electronic knob is faulty, it can be replaced. This should only be done by trained personnel.
Remove the snap ring between the electronic knob and locking cam and pull the electronic knob gently
out of the cylinder.
CAUTION
Parts falling out of the cylinder
When pulling out the mechanical knob make sure that the
parts do not fall out of the cylinder.

Then insert the new electronic knob into the cylinder as far as it goes and turn it slowly vis-a-vis the lock-
ing cam until all the parts mutually engage and the electronic knob is completely inside the cylinder. Only
then can the electronic knob be fixed using the snap ring.
This procedure become easy if the product is engaged when interlocking and turning.
3.4 Check
Check the function of the electronic locking system before installing in the door. In the unauthorised state,
the locking cam has to be disengaged from the electronic knob. Once an authorised transponder is held
up, the locking cam has to engaged with the electronic knob. The locking cylinder should be installed in
the door only if it is working properly.

4Rotation of the cylinder
4.1 Relates to the following variants
CX6162
CX2162
4.2 Necessity of the measure
When ordering, the external and internal dimensions of the fixing screw were mixed up, the cylinder has
to be rotated.
The cylinder dimensions have to be changed. Other parts are required here which will be included when
the cylinder is re-ordered.
4.3 Procedure
If the cylinder needs to be rotated, both the electronic knob and the mechanical knob have to be separated
from the cylinder. This should only be done by trained personnel.
Remove the snap ring between the locking cam and the mechanical knob.
CAUTION
Parts falling out of the cylinder
When pulling out the mechanical knob make sure that the
parts do not fall out of the cylinder.

Remove the parts out of the cylinder carefully. Do not change the position and sequence. Different parts
are used depending on the cylinder dimensions.
Remove the snap ring from the electronic knob, pull it carefully out of the cylinder and remove the lock-
ing cam.
Rotate the cylinder and hold the locking cam in the cylinder opening, such that the four inner tappets
point towards the mechanical knob. Then insert the electronic knob into the appropriate side of the lock-
ing cylinder and secure it with the snap ring.
From a cylinder dimension of 45/xx onwards, the locking cam can be inserted in the cylinder
opening even after mounting the electronic knob.

Insert the parts into the cylinder in the same position and sequence in which they were removed.
Then insert the mechanical knob into the cylinder as far as it goes and turn it slowly vis-a-vis the locking
cam until all the parts mutually engage and the mechanical knob is completely inside the cylinder. Hold
the locking cam centrally in the cylinder opening so that the parts can slide through to the electronic
knob. The grub screw of the mechanical knob should now point downwards. If it is pointing upwards,
then the mechanical knob has to be pulled slightly out of the locking cylinder, rotated by 180° and rein-
serted. Only then can the mechanical knob be fixed using the snap ring.
4.4 Check
Check the function of the electronic locking system before installing in the door. In the unauthorised state,
the locking cam has to be disengaged from the electronic knob. Once an authorised transponder is held
up, the locking cam has to engage with the electronic knob. When turning the mechanical knob, it
should always take the locking cam with it. The locking cylinder should be installed in the door only if it is
working properly.

When cylinders are ordered separately, the internal components of the cylinder may fall out when remov-
ing the transport protection, as these are held securely in the cylinder only after the electronic knob is in-
serted. Note the following when inserting the internal components:
1. The knob shaft (2) need not be removed for the assembly.
2. The locking cam (8) is positioned in the cylinder opening when assembling the internal parts.
The carrier knobs inside the locking cam have to point in the direction of the knob shaft (2).
3. The number and length of the filler parts (5) depends on the cylinder length. They are inserted in-
to the cylinder such that the two carrier lugs point towards the electronic knob (7).
4. The coupling carrier (6) has two slots for the two carrier lugs of the filler parts (5) or the knob
shaft (2). It has to point towards the knob shaft (2).
The side of the coupling carrier (6), which points in the direction of the electronic knob (7) has
four smaller slots.

Description
Knob shaft

chanical side via the internal components of the locking
cylinder to the locking cam.
Locking cam
Part of locking cylinder which rotates inside the lock during
the locking operation and actuates the lock.
Filler parts
Transmits the rotational movement to the locking cam. They
compensate for the different lengths of the locking cylinder.
Coupling carrier
During coupling of the electronic knob, it engages with the
coupling carrier and thus transmits the rotational movement
to the locking cam.
