Safety

This section is intended to support your safety and the safety of the system users.
Ä Please read this section carefully before you work with a MSI 400 system.
2.1

Qualified persons

The modular MSI 400 safety control may only be installed, commissioned, and maintained by qualified per-
sons.
Qualified persons are those who
• have suitable technical training and
• have been trained by the machine operator in the operation and applicable safety guidelines and
• have access to the MSI 400 operating instructions and have read said instructions and have duly noted
these and
• have access to the operating instructions for the safety devices connected to the safety control (e.g.
safety light curtain) and have read them and duly noted them.
2.2

Areas of application of the device

The modular MSI 400 safety control is an adjustable control for safety applications. It is usable
• as per EN 61508 up to SIL 3
• as per EN 61131-6 up to SIL 3
• as per EN 62061 up to SIL CL 3
• as per EN ISO 13849-1:2015 to performance level e / category 4
• as per EN 81-1
• as per EN 50156-1
• The safety function must be tested at least once annually
• A consistent redundant structure must be implemented
• If relay expansion modules are used, the correct switching of the relays must be monitored using
feedback contacts (EDM)
• The requirements of EN 50156-1, Section 10.5.6, must be considered
The level of safety actually achieved depends on the external wiring, the implementation of the wiring, the
parameterization, the selection of the command encoder, and their arrangement on the machine.
Opto-electronic and tactile safety sensors (e.g. light curtains, laser scanners, safety switches, sensors,
emergency stop switches) are connected and logically linked at the modular safety control. The corres-
ponding actuators on the machine or systems can be securely switched off via the switch outputs of the
safety control.
