Compact electronic knob cylinder
10
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.

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.
