In combination with highly coded, transponder-based keys, the key adapter CKS2 forms a safe system that meets the highest safety requirements for machine and installation lockout and starting. Thanks to the integrated evaluation electronics, the compact CKS2 system can solve many tasks for you. The CKS2 system can be integrated into installations with the highest safety requirements, such as category 4 / PL e according to EN ISO 13849-1. CKS2 can be used in an installation either individually as a compact system with integrated evaluation electronics or separately as a submodule in the MGB2 Modular door locking system.
CKS2 key adapter – How it works?
Keys are taught-in directly on the key adapter, without complex programming. When the key is inserted into the key adapter, the data on the key are read and checked for validity. If the key is recognized as valid, the safety outputs switch.
The CKS2 system can be flexibly adapted to application specific requirements. As a lockout system, key transfer system or authorization system, the CKS2 system is the right choice wherever dangerous machine movements must be safely started or stopped independently of the existing safeguards.
CKS2 MSM can be linked to PROFINET / PROFIsafe or EtherCAT / EtherCAT FSoE using the bus module MBM.
Application example: Maintenance operation of automatic warehouse
The safety door of each transport aisle is secured by a guard locking device MGB2 Modular with MSM-CKS2. No key is inserted during automatic operation.
- To stop the installation in the respective aisle, the assigned key is inserted, and a pushbutton is pressed.
- They key is withdrawn, and the door can be opened to access the aisle.
- After the aisle is accessed, the door is closed from the inside. The same key is inserted into a second key adapter in the interior. Pressing a pushbutton on an extension module MCM controls the guard locking of the safety switch.
- The automatic storage and retrieval equipment can now be controlled manually using additional pushbuttons or a hand-held pendant station.
- The key is withdrawn when the automatic storage and retrieval equipment reaches the correct position. The automatic storage and retrieval equipment is safely stopped. Work can be performed inside.
- To leave the aisle, the key is inserted into the inner key adapter on the door. The door is opened using a pushbutton.
- The key is withdrawn, and the aisle is left.
- The safety door is closed from the outside. The key is inserted. Guard locking is controlled via a pushbutton. The safety door is locked, and the installation can be started. The key is withdrawn again to continue automatic operation.
The CKS2 system can be flexibly adapted to application-specific needs. It can be used as a Lockout–tagout system, for identifying user permissions, selecting the device’s operating mode, or as a key transfer system.
The design of the safety system begins with reviewing the maintenance sequence and the area’s layout to be protected. Carefully defined and the correct placement of the system components are important to achieve the most cost-effective and easy-to-use maintenance process.
