6.4.2  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 
cylinder. 
Note: If you cannot see any screw thread on the end of the pipe, this cylinder 
has a new flange mounting (in this case, refer to Point 6.4). 
2.  Put the flange onto the end of the pipe; the side of the flange with the screw 
thread faces away from the cylinder. The flange contains a crosspin that sticks 
out of the interior diameter. This crosspin must catch in the longitudinal slot of 
the pipe. Push the flange up against the stop on the pipe. 
3.  Holding it in this position, fix the three setscrews very tightly with the Allen key 
(1.5 mm). Check whether the setscrews are really tightly screwed, because 
this is important for correct functioning. 
4.  Fix the electronics module to the flange with the Allen screws that are parallel 
to the battery (same Allen key as above). Guide the cable through the recess 
next to the connector. Make sure that the cable is not pinched. 
5.  Connect the cable to the electronics socket and lay it so that it is flat on the 
electronics covering and not in the way when screwing on the knob (danger of 
pinching). 
6.  Use an authorised transponder to couple the half cylinder and tightly screw 
the knob in until the stop
. Make sure that the knob is screwed on up to the 
stop (important for the function). 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. 
7.  Firmly hold the knob and use the special tool for half cylinders to firmly screw 
the locknut onto the knob.
