Safety instructions
Electrical equipment must only be installed and assembled by qualified electricians. Failure to observe these instructions may lead to damage to the device, fire, or other hazards.These instructions are an integral component of the product, and must be retained by the end user.
Function
Key switches/key push-buttons are used to prevent unauthorised operation of the connected loads. These devices are intended for the installation of profile half cylinders according to DIN with a length of 40 mm. Recommendation: use a profile half cylinder with an adjustable lock bit to allow adaptation of the locking characteristics to various requirements.
Installation
Adjusting the lock bit on the profile half cylinder
The lock bit position of some profile half cylinders (Berker: order no. 1818..) can be changed in 45° increments when the key is removed (Figure 1). To change the switching position, the lock bit can be guided in the fork (1) of the switch/push-button insert, or can contact the fork laterally (2) (Figure 2). The switching positions in which the key can be removed depend on the lock bit position of the profile half cylinder being used. If the lock bit is guided in the fork, it can only be removed in one switching position (overview in the appendix). Furthermore, the lock bit position determines whether the cover can be removed with the lock cylinder without the key, or whether it is protected against removal by the cover plate (antidismantling protection). The cover is secured in the lock bit settings 90°, 135°, 22,5°, and 270° (Figure 3). Put the locking pin into the lock bit from the side and move the lock bit to the desired position. (Figure 4)
Installing the profile half cylinder in the centre plate
The lock bit on the profile half cylinder is adjusted.
- Using key, move lock bit on profile half cylinder (4) to 180° position and guide it through the centre plate (5) from the front (picture 5).
- Connect lock cylinder and centre plate using the locking screw (6).
Connecting and mounting the key switch
DANGER!
Electrical shock when live parts are touched. An electric shock can lead to death: Isolate from mains voltage before connecting.
The key switch/key push-button is intended for installation in a connection box according to DIN 49073, Part 1 with screw fastening.
- Connect the switch insert/push-button insert on the rear according to the labelling.
- Position switch insert/push-button insert (8) in the connection box (7) and screw in place. Note marking TOP/OBEN. (Bild 6)
- Fit frame (9) on the switch insert/push-button insert.
- Using the key, move lock bit into position, fit centre plate and profile half cylinder (10) and screw in place. Depending on requirements, guide the position of
the lock bit in or next to the fork of the switch insert (see “Adjusting the lock bit on the profile half cylinder) - Remove the key.
- Snap-on cover (11) for the profile half cylinder
