Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Introduction Safety Information Target Group, Personnel Responsibility for planning, assembly, commissioning, operation, maintenance, and dismounting lies with the plant operator. Only appropriately trained and qualified personnel may carry out mounting, installation, commissioning, operation, maintenance, and dismounting of the product. The personnel must have read and understood the instruction manual and the further documentation.
Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Introduction Symbols Used This document contains symbols for the identification of warning messages and of informative messages. Warning Messages You will find warning messages, whenever dangers may arise from your actions. It is mandatory that you observe these warning messages for your personal safety and in order to avoid property damage.
Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Product Description Product Description Function General This signal conditioner provides galvanic isolation between field circuits and control circuits. The de-energized to safe (DTS) function is permitted for SIL 3 and PL e applications. For testing of the relays, test terminals can be used. The test mode will be indicated by a LED. KFD0-RSH-1.1D.F1 The device is supplied with a replaceable fuse of 2.5 AF.
The test input may not be used during normal operation. The test input may be used for test only. Note For corresponding connections see datasheet.

Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Planning Planning System Structure 3.1.1 Low Demand Mode of Operation If there are two control 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.
Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Planning Assumptions The following assumptions have been made during the FMEDA: • Failure rates are constant, wear is not considered. • Failure rate based on the Siemens standard SN 29500. • The safety-related device is considered to be of type A device with a hardware fault tolerance of 0.
Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Planning Safety Function and Safe State Safety Function The safety function of the device is defined: Whenever the input of the device is de-energized, the DTS output is not conducting. Safe State In the safe state of the safety function the DTS output is open (non-conducting). Reaction Time The reaction time is <...
As noted in DIN EN 61508-2:2011 note N3, appropriate measures taken by the manufacturer and plant operator can extend the useful lifetime. Our experience has shown that the useful lifetime of a Pepperl+Fuchs product can be higher if the ambient conditions support a long life time, for example if the ambient temperature is significantly below the maximum ambient temperature.
Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Mounting and Installation Mounting and Installation Mounting and Installing the Device Observe the safety instructions in the instruction manual. Observe the information in the manual. Observe the requirements for the safety loop. Connect the device only to devices that are suitable for this safety application. Check the safety function to ensure the expected output behavior.
Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Operation Operation Danger! Danger to life from missing safety function If the safety loop is put out of service, the safety function is no longer guaranteed. • Do not deactivate the device. • Do not bypass the safety function. •...
Functional Safety K*D0-RSH-1.1D.(F)*, HiC5861(Y1) Operation Proof Test This section describes a possible proof test procedure. The user is not obliged to use this proposal. The user may consider different concepts with an individual determination of the respective effectiveness, e. g. concepts according to NA106:2018. According to IEC/EN 61508-2 a recurring proof test shall be undertaken to reveal potential dangerous failures that are not detected otherwise.
