Safety Manual SIL HiD202*(SK), HiD2030(SK) With regard to the supply of products, the current issue of the following document is applicable: The General Terms of Delivery for Products and Services of the Electrical Industry, published by the Central Association of the Electrical Industry (Zentralverband Elektrotechnik und Elektroindustrie (ZVEI) e.V.) in its most recent version as well as the supplementary clause: "Expanded reservation of proprietorship"...
(supplied internally). The versions ending with SK are designed to provide a sink mode current output on the safe area terminals (supplied externally). While HiD2025(SK) and HiD2029(SK) are one channel versions, the HiD2026(SK) and the HiD2030(SK) provide two channels.
Safety Manual SIL HiD202*(SK), HiD2030(SK) Introduction HiD2025(SK), HiD2026(SK) The output is isolated from the input and referenced to the power supply common. HiD2029(SK), HiD2030(SK) These devices can also be used with 2-wire current sources. A separate fault indication output on the bus indicates that the input signal is outside the range 0.2 mA ...
Safety Manual SIL HiD202*(SK), HiD2030(SK) Planning Planning System Structure 2.1.1 Low Demand Mode of Operation If there are two loops, one for the standard operation and another one for the functional safety, then usually the demand rate for the safety loop is assumed to be less than once per year.
Safety Manual SIL HiD202*(SK), HiD2030(SK) Planning Assumptions The following assumptions have been made during the FMEDA analysis: Only one input and one output are part of the considered safety function (only 2-channel version). Failure rate based on the Siemens SN29500 data base. ...
Safety Manual SIL HiD202*(SK), HiD2030(SK) Planning Safety Function and Safe State Safety Function The safety function of the devices is the transfer of the analog signals from the input to the output with a tolerance of 2 %. Input signals Output signals 0/4 mA …...

Safety Manual SIL HiD202*(SK), HiD2030(SK) Safety Recommendation Our experience has shown that the useful life time of a Pepperl+Fuchs product can be higher if there are no components with reduced life time in the safety path (like electrolytic capacitors, relays, flash memory, opto coupler) which can produce dangerous undetected failures and if the ambient temperature is significantly below 60 °C.
Safety Manual SIL HiD202*(SK), HiD2030(SK) Proof Test Proof Test Proof Test Procedure According to IEC 61508-2 a recurring proof test shall be undertaken to reveal potentially dangerous failures that are otherwise not detected by diagnostic tests. The functionality of the subsystem must be verified at periodic intervals depending on the applied PFD in accordance with the data provided in this manual.
