6.5 Installation Behind Blanks for Half Cylinders With 2 Setscrews
(Old Flange Mounting)
6.5.1 Removal of the Knob and Flange of the Half Cylinder
1. Firmly hold the knob and remove the locknut on the back of the knob from the
knob with the special tool for half cylinders.
2. Use an authorised transponder to couple the cylinder and then unscrew the
knob. While doing this, you must firmly hold the catch with your hand if the half
cylinder is not installed. If the half cylinder is installed, the catch is held by the
stop within the lock.
3. Carefully pull the cable out of the socket-contact in the electronics but do not
remove the insulation sleeving. The electronic covering is thermally welded on
and also remains on the unit.
4. Remove the two Allen screws that are parallel to the battery from the flange
with an Allen key (1.5 mm). Remove the electronics module.
5. Remove the setscrew on the outer circumference of the flange (same Allen
key). Note: If you can see 3 setscrews here, this cylinder has a new flange
mounting (in this case, refer to Point 6.4)
6. The fore-part of the pipe, which sticks out of the profile, contains two slots on
which you can position the special tool (offset 90° to the lengthwise slot which
guides the cable). The narrow end of the installation tool can move into this
slot. This ensures that the pipe cannot twist.
7. Now you can unscrew the flange without the pipe also turning.
8. Remove the locknut.
9. Now you can install the blank.
6.5.2 Installing the Knob and Flange of the Half Cylinder
1. Put on the locknut. The flat surface with the bore holes faces away from the
door.
Note: If you cannot see any screw thread on the end of the pipe, this cylinder
has a new flange mounting (refer to Point 6.4).
2. Please note the two lateral impressions on opposite sides of the pipe. The
lateral setscrews of the flange must fit into this later in order to guarantee that
