Art.-Nr.: KXC-50-AA; KXC-50-AA-SRR; KXC-50-AA-SRL • Datasheet: n. a.

These instructions show the installation of semi-lock cylinder KXC-50-XX/-SRR/-SRL for Rittal comfort handles of type TS, TS IT, SE, PC, IW (TS 8611.070).

The following explains the installation of semi-locking cylinders with and without spring return.

The required direction of rotation for opening the lock and the cylinder length must be determined in advance. Instructions for measuring can be found here: Measuring the locking cylinder

Half-cylinder with spring return (KXC-50-AA-SRR/-SRL)

With the principle of spring return, the knob can only be turned by 90° and returns to its initial position after the opening mechanism has been actuated. The initial position of the locking cam (1) is explained in the following steps.

To enable the half cylinder to be mounted in the comfort grip, the bracket (2) must first be attached to the half cylinder using the fixing screw (3).

Please note that the locking cam (1) must face upwards to reach the actuating plate of the Rittal handle. The position of the locking bit (1) can be adjusted by loosening the screw (5). After loosening the screw, the locking cam can be moved into the desired position.
To avoid permanent opening of the handle and problems when installing the cylinder in the handle housing, the locking cam should not be positioned directly on or under the actuating plate. (See Figure 1 in the section "Inserting the half cylinder into the handle housing" in this document)

The position of the locking cam (1) should be selected 90° before the actual position of the opening mechanism (see picture 1: inserting the half cylinder into the handle housing)

The positions for the locking cam are defined by threaded holes. If the screw (5) cannot be screwed in, the locking cam must be moved further until the screw is positioned over a hole provided for this purpose.
The screw can then be screwed in without difficulty. Please note the direction of rotation of the locking cam when opening the Kentix DoorLock. When opening, the locking cam must be able to reach the actuating plate of the Rittal handle.

Half-cylinder without spring return (KXC-50-AA)

To enable the half cylinder to be mounted in the comfort grip, the bracket (2) must first be fixed to the half cylinder using the fixing screw (3).

In contrast to the locking cylinder with spring return described above, no positioning of the locking cam is required for this variant. In the case of the half cylinder without spring return, the locking cam can be turned through 360° in both directions.

The half cylinder without spring return can be used for locks with closing direction right or left. 

Inserting the Half Cylinder into the Handle Housing

Now the half cylinder is inserted into the housing of the handle and fixed with the enclosed screw. The opening for the lock must be visible from the front and the cylinder must not protrude over the edge of the housing.

For better visibility, the protective plate was not mounted for the example. It is mounted with the same screw as the cylinder, as shown in the second picture. This also serves to protect the actuating plate and locking cylinder.

Finally the Kentix DoorLock-DC is pushed into the cylinder from the front until the DoorLock engages.
