Ex. No. Protective door monitoring with automatic start Category 4 2.12 acc. to EN 954-1 with/without operational switching with a safety fuseless load feeder 3RA7 Function Description of the functionality This Safety Functional Example describes a mechanically isolating protective mechanism in the form of a protective door. The most frequently used solution for plants and machines to secure hazardous areas is mechanically isolating protective equipment or access hatches. In this case, the function is to monitor unauthorized entry into plant and system areas as well as to prevent potentially hazardous machine functions if the protective equipment - in this case protective door - is not closed. Position switch with separated actuator Actuator Protective door opened Protective door closed The protective door is monitored by two SIRIUS position switches with positively-opening contacts using a safety fuseless load feeder according to Category 4 in compliance with EN 954-1. If this protective door is opened, the load feeder safety shuts down (de-activates) the contactors, connected in series, with its positively-driven contacts according to stop Required components Hardware components Note The functionality was tested using the specified hardware components. Products that are similar but deviate from the list above can be used (e.g. a different safety load feeder). However, in this case, please carefully note that it may be necessary to make modifications as to how the hardware components are connected-up (e.g. another connection assignment). 50 Functional Example No. CD-FE-I-016-V10-EN G_FB_XX_038 Category 0 in compliance with EN 60204. In this particular example, a drive is stopped. If the protective door is closed and after the position switch and downstream contactors have been checked, then the drive automatically starts. It is possible to operationally switch (in/out) the contactors. Either a floating (electrically isolated) contact is connected between terminal 3 and terminal 4 (refer to „Wiring of the hardware components“ page 51) or a non-floating (non-electrically isolated) output (24 V DC) - e.g. from a standard PLC - is connected at terminal 4. The operational switching has a lower priority than the safety function. If the operational switching is no longer required, a wire link (jumper) should be connected between terminal 3 and terminal 4. Note The position switches must be arranged so that they are not damaged when they are approached and passed. This is the reason that they may not be used as mechanical endstop. Advantages/customer benefits ■ Pure hardware engineering without having to configure/program software ■ A low scope of simple wiring ■ Space-saving design using our compact safety relay ■ Can be simply expanded using expansion devices Component Type MRPD / Ordering data Qty Manufacturer SIRIUS position switch Position switch with separate actuator 3SE2 243-0XX40 2 Siemens AG Actuator for position switch Radius actuator 3SX3 228 2 Safety load feeder 3RA7 3RA7112-4CA26-0AB4 1
