Central controller RJ
For the central interlock control system
Characteristics
The central controller RJ is the core of the central interlock control system. All control boards are placed in the central controller RJ contrary to the peripheral system where they are located in the respective control terminals. The standard version provides 2 control boards for 2 doors. In case the interlock control system consists of more doors, the central controller RJ will contain the necessary number of control boards.
The main advantage of the central interlock control system is it requires even less connection cables to the doors and all relations can be adjusted in the central controller RJ.

Structure
The central interlock control system has been designed for systems with up to 5 doors. If necessary, it can be used for up to 8 doors. The central controller RJ consists of a basic circuit board on which are plugged the control boards of the different doors. Above each control board are 2 sockets:
- green socket for green connection cable to the operating terminal BTZ on the door.
- blue socket for the connection cable to the locking device of this door.
The power cable of the power pack is plugged in the 2-pin socket down in the right corner.
Options
Beside the basic functions several additional options can be achieved. The most important ones are listed below, with the necessary accessories.
- Global emergency-open GNA: In case all doors of the interlock system should open once the emergency-open switch on one of the operating terminals has been pressed (global emergency-open), this can easily be achieved – also later – by adding a relay (part no. 710953) to the central controller RJ. This relay is simply plugged in the provided socket.
- LAN module: It is possible to transmit status information and errors from the central controller RJ to a facility mangement system. For this purpose the central controller RJ can be upgraded in production with an additional circuit board (part no. 710954). This allows the facility management system e.g. to trigger an alarm, to pass an information to the ventilation system etc. The LAN module is not included in the standard version!
- Achieving special functions as e.g. the discretion circuit: For this purpose an 8-pin screw-type terminal is provided in the central controller RJ.
- Time-delayed opening: In case it should be possible to reopen some doors only with a time delay, this can be adjusted by a jumper on the respective control board.
- Integration of door operators: It is also possible to integrate door operators on (some) doors of the interlock system. In this case the terminals on the respective doors have to be without emergency-open and for the operator a separate emergency-open switch has to be mounted.
Dimensions
All dimensions in mm
The strain relief of the incoming and outgoing cables is achieved by fixing the cables with tie wraps to the two cable support brackets. The cable inlets are sealed dust proof by cellular material. For fixing 4 borings of Ø 5.4 mm are provided in the casing of the central controller RJ.
