    Modular Safety Control System MSC 1. About this document 1.1. Scope These operating instructions are valid for the Modular Safety Control System MSC. These operating instructions and any brief instructions enclosed form the complete user information for your device. 1.2. Target group Design engineers and installation planners for safety devices on machines, as well as setup and servicing staff possessing special expertise in handling safety components.

  • Page 8: Introduction

    WARNING Ì MSC achieves the following safety levels: SIL 3, SILCL 3, PL e, cat. 4, type 4 as per the applicable standards. However the final SIL and PL safety categories for the application are dependent on the number of safety components, their parameters and the connections made, as per the risk analysis.

    In addition, 8 inputs and 16 outputs are available and can be controlled using sensors (via the fieldbus). The number of inputs in the system can be increased using the MSC extension modules FI8, FI16 and FM4 such that more external devices can be connected.
  • Page 11 All this is achieved using a straightforward, intuitive graphic user interface. The configuration undertaken on the PC is transferred to the MSC-CB via a USB connection. The file is saved in the MSC-CB and can also be saved on the proprietary M-A1 memory card (accessory). In this way it is possible to copy the configuration to a different MSC-CB module quickly.

    5. Installation 5.1. Mechanical fastening Fasten the modules of the MSC system to a 35-mm DIN rail as follows: 1. Connect together a number of rear 5-pin MSCB plug connectors to suit the number of modules to be installed. 2. Fasten the row of plug connectors assembled in this manner to the DIN rail (first hook on at the top).

    5.3.3.2. RESTORE function If the module MSC-CB is faulty, it can be replaced with a new module. As the entire configuration is saved on the M-A1 memory card, it is only necessary to insert this card in the new module and switch on the MSC system, the backed up configuration will then be loaded immediately.

  • Page 80: Checking The System

    After the project has been validated, uploaded to the module MSC-CB and all safety components have been connected, the system must be checked for correct operation. This check is made by forcing a status change for each safety component connected to MSC to check whether the status of the outputs also actually changes.
