Page 6: Safety Information
Functional Safety M-LB-(Ex-)4000-System 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 M-LB-(Ex-)4000-System 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 M-LB-(Ex-)4000-System Product Description Product Description Function This manual describes solely the safety function and safe state of the surge protection barrier as part of the surge protection system. Danger! Danger to life from wrong usage of the device The protection of the safety loop against overvoltage is not the safety function of the surge protection barrier. -

Page 10: Planning
Functional Safety M-LB-(Ex-)4000-System 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 M-LB-(Ex-)4000-System Planning Assumptions The following assumptions have been made during the FMEDA: • The device will be used under average industrial ambient conditions comparable to the classification stationary mounted according to MIL-HDBK-217F. Alternatively, operating stress conditions typical of an industrial field environment similar to IEC/EN 60654-1 Class C with an average temperature over a long period of time of 40 ºC may be assumed. -
Page 12: Safety Function And Safe State
Functional Safety M-LB-(Ex-)4000-System Planning Safety Function and Safe State The safety function of the surge protection barriers depends on the signal loop to which it is attached. The interference on safety relevant signals (e. g. 4 mA to 20 mA analog signal) that pass through the devices was evaluated. - Page 13 Functional Safety M-LB-(Ex-)4000-System Planning Safety Function The safety function of the surge protection barrier is to behave like a piece of copper wire, passing through the process signal without being altered. Reaction Time The reaction time is < 1 ms. Note The fault indication output is not safety relevant.

Page 21: Useful Lifetime
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. -
