Page 6: Safety Information
Functional Safety HiC283* 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. -
Page 7: Symbols Used
Functional Safety HiC283* 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. -
Page 8: Product Description
Functional Safety HiC283* Product Description Product Description Function General This isolated barrier is used for intrinsic safety applications. The device transfers digital signals from NAMUR sensors or dry contacts from the hazardous area to the non-hazardous area. Via switches the mode of operation can be reversed and the line fault detection can be switched off. -

Page 10: Planning
Functional Safety HiC283* 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. -
Page 11: Assumptions
Functional Safety HiC283* Planning Assumptions The following assumptions have been made during the FMEDA: • Failure rate based on the Siemens standard SN 29500. • Failure rates are constant, wear is not considered. • External power supply failure rates are not included. •... -
Page 12: Safety Function And Safe State
Functional Safety HiC283* Planning Safety Function and Safe State Safe State The safe state of output I and output II is the high impedance state or the fault state. Safety Function HiC2831* Switch Position Function Output I and output II Normal mode of If a low current is present at input I, operation... - Page 13 Functional Safety HiC283* Planning Line Fault Diagnostics If the line fault detection is enabled (mandatory, see datasheet), the input circuit is monitored in all device versions. If a line fault is detected, the outputs change in the fault state (safe state). Note The fault indication output is not safety relevant.

Page 15: Useful Lifetime
Functional Safety HiC283* Planning Useful Lifetime Although a constant failure rate is assumed by the probabilistic estimation this only applies provided that the useful lifetime of components is not exceeded. Beyond this useful lifetime, the result of the probabilistic estimation is meaningless as the probability of failure significantly increases with time. -
Page 16: Mounting And Installation
Functional Safety HiC283* 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. -
