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.

EUCHNER) on the rear side of every module. 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. FM4 also provides 8 outputs of type OUT_TEST.
Page 11 All this is achieved using a straightforward, intuitive graphic user interface. The configuration on the PC is sent via a USB connection to base unit MSC-CB or MSC-CB-S. The file is saved in MSC-CB/ MSC-CB-S 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 base unit quickly.

Important! The supplied MSCB plug connector and a further MSCB plug connector are required for the connection to the MSC-CB/MSC-CB-S to install an extension module. This can be ordered separately as an accessory. (Translation of the original operating instructions) 2121331-08-07/22...

3. Mount the row of expansion plugs on the DIN rail. Hook on from top to bottom. 4. Mount the MSC module on the DIN rail. Hook on from top to bottom. Push module into place until it noticeably engages.
Page 14: Calculation Of The Safety Distance For An Item Of Espe Connected To The Msc System
5.2. Calculation of the safety distance for an item of ESPE connected to the MSC system All electro-sensitive protective equipment that is connected to the MSC system must be arranged at a distance that is at least the minimum safety distance S such that the danger zone can be reached only after the machine’s hazardous move- ment has stopped.
Page 15: Electrical Connections
Modular Safety Control System MSC 5.3. Electrical connections The modules of the MSC system are equipped with terminal blocks for the electrical connections. Each module can have 8, 16 or 24 connections. Each module also has an MSCB plug connector on the rear (for the commu- nication with the base unit and the other extension modules).
Page 16: Notes On
1) Note on the scope of the UL approval: the devices have been tested as per the requirements of UL508 and CSA/ C22.2 no. 14 (protection against electric shock and fire). The connections for each module in the MSC system are listed in the tables below: 5.3.2.1.

NOTICE If the file on the memory card is not identical to the file in the MSC-CB/MSC-CB-S, the configuration data in the MSC-CB/MSC-CB-S will be overwritten and therefore permanently deleted.
Page 19: Restore Function
If the MSC-CB/MSC-CB-S module is faulty, it can be replaced with a new module. As the entire configuration is saved on the M-A1 memory card, all that is necessary is to insert this card in the new module and switch on the MSC system; the backed up configuration will then be loaded immediately.

7.1.4. RESTART_FBK Using the RESTART_FBK signal, MSC can monitor a feedback loop signal (External Device Monitoring – EDM) from external contactors; both manual and automatic forms of starting can be programmed (see list of the possible connections in Table 18).
Page 34: Outputs
In this test, each OSSD output is periodically (every 20 ms for MSC-CB, every 600 ms for MSC-CB-S) short-circuited to 0 V for a very short time (<120 μs). The control system can put the system into a safe state if the test results are inconsistent.
Page 35 Modular Safety Control System MSC Each OSSD output can be configured as shown in Table 19: The output is activated, as per the configuration defined by the EUCHNER Safety Designer software, only if 24 VDC is applied to the related Automatic input RESTART_FBK.

Page 90: Checking The System
The system must be checked for correct operation after the project has been validated and uploaded to the MSC-CB/MSC-CB-S module and all safety components have been connected. 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.
Page 91: Item-Specific Function Blocks
If the OUTPUT is at logic level “High” (TRUE), the FBK signal must be at the logic level “Low” (FALSE) within the time set and vice versa. Otherwise, the OUTPUT output changes to the Low level (FALSE) and the error is signaled on the base unit MSC-CB/MSC- CB-S by the flashing of the CLEAR LED for the OSSD in the error mode.
Page 92: Safety Output (Single-Double Ossd)
Each SINGLE_OSSD output has a corresponding RESTART_FBK input. The RESTART_FBK input appears for OSSD outputs ¨ of the MSC-CB-S and FI8FO4S modules only if manual reset or feedback loop monitoring is activated. The RESTART_FBK input is mandatory on the AH-FO4SO8 module and must be connected as described in the RESTART_FBK section.

Page 94 If the OUTPUT is at logic level “High” (TRUE), the FBK signal must be at the logic level “Low” (FALSE) within the time set and vice versa. Otherwise, the OUTPUT output changes to the Low level (FALSE) and the error is signaled on the base unit MSC-CB by the flashing of the CLEAR LED for the OSSD in the error mode.
