INTRODUCTION 1.1. Purpose of the document The subject of manual are rail-mounted smart temperature transmitters LI-24ALW Safety. The manual applies to the following versions: standard, intrinsically safe Exi and flameproof Exd. The manual contains data, tips and general recommendations for safe installation and operation of the transmitters, as well as troubleshooting in case of possible failure. -
Page 7: Definitions And Abbreviations
EN.IO.LI.24.ALW.SFT 1.3. Definitions and abbreviations Table 1. Definitions and abbreviations. Item Abbr. Meaning “Lower Range Value” – the value of the set range expressed in the units of temperature, re- sistance or voltage corresponding to the current of 4,000 mA, i.e. 0% of the output setpoint. The set range must not exceed limits which depend on the selected measurement type. -
Page 8: Transmitter Set Range
EN.IO.LI.24.ALW.SFT 1.4. Transmitter set range The figure below shows the transmitter LRV/URV set range, limits related to the LRL/URL permissible set range, LPL/UPL digital processing range of the A/D measuring transmitter. As standard, current values of 4 mA/20 mA are assigned to LRV/URV points. In order to obtain reverse characteristics, it is possible to reverse the assignment so that the LRV/URV points are assigned to 20 mA/4 mA currents. -

HART communication. 8.1. Alarm configuration The LI-24ALW Safety transmitter features an advanced internal diagnostics resulting from the requirements of PN-EN 61508 standard. The internal diagnostics of the transmitter monitors the oper- ation of its electronic circuits, process parameters and environmental parameters, thus ensuring an increased level of functional safety. -
Page 17: Configuration Of The Operating Mode
EN.IO.LI.24.ALW.SFT The transmitter diagnostics continually tests the process parameters of temperature if the measured process variable value increases above the upper value of the base range relative to URL, when UPL is reached, the diagnostics will trigger alarm I_AL<3,600 mA. Temperature return below UPL point will result in deactivation of the alarm and restoration of the transmitter to its normal operation;... -
