Do you have a question about the Murr Elektronik MIRO SAFE+ Switch H L 24 and is the answer not in the manual?
The MIRO SAFE+ Switch HL 24 (Article No. 3000-33113-3020012) is a safety monitoring module designed for use in safety circuits, specifically for installation in control cabinets. It serves to safely evaluate signals from positively-driven position switches used in safety functions for laterally displaceable, rotatable, and removable protective devices, as well as from emergency stop command devices, safety magnetic switches, and AOPDs (Active Opto-electronic Protective Devices).
The safety function of the MIRO SAFE+ Switch HL 24 is defined by the opening of the enabling outputs 13-14, 23-24, and 33-34 when inputs S11-S12 and/or S21-S22 are opened. The safety-relevant current paths with output contacts 13-14, 23-24, and 33-34 meet the requirements for Category 4 - PL e according to DIN EN ISO 13849-1, SIL 3 according to DIN EN 61508-2, and SILCL 3 according to DIN EN 62061, considering a PFH-value analysis. To determine the Performance Level (PL) of the entire safety function (e.g., sensor, logic, actuator), an analysis of all relevant components is required.
The device features an internal electronic fuse with a trip current of >500 mA for the operating voltage and >50 mA for the S11, S21 inputs, with reset after interruption of the supply voltage. It supports both automatic start and monitored start via a start button. The module includes cross-circuit detection, wire-break detection, and earth-fault detection for its monitored inputs.
The MIRO SAFE+ Switch HL 24 is designed for easy installation on a DIN rail. The front cover can be opened and removed using a screwdriver, allowing access to the terminals. The device must only be operated with the front cover mounted. The module supports various wiring configurations for safety switches, including single-channel and dual-channel setups, with or without feedback loops, and for different types of emergency stop devices and safety magnetic switches. It is crucial to adhere to the specified minimum requirements for switching capacity, voltage, and current when connecting sensors, especially in series. The device is designed for use in industrial environments, as indicated by its EMC compliance.
Regular visual inspection and functional tests are required for the safety monitoring module. This includes checking for correct wiring, proper fastening, and checking for damage. A functional check of the device is also necessary. The manufacturer recommends periodic checks according to the BGHW (German Social Accident Insurance Institution for the Wood and Metalworking Industries) guidelines, at least once a year. Damaged or defective components must be replaced. The device is designed for disassembly and disposal at the end of its service life by pushing up the bottom of the enclosure and hanging it slightly forward. Any repairs, modifications, or alterations not authorized by the manufacturer are strictly prohibited for safety reasons and will void the manufacturer's liability.
