Page 6: Introduction
1.1. Purpose of the document The subject of manual are rail-mounted smart temperature transmitters LI-24L and head-mounted smart temperature transmitters LI-24G, hereinafter referred jointly to as LI-24L(G). The manual ap- plies to the following versions: standard and intrinsically safe Exi. -
Page 7: Definitions And Abbreviations
EN.IO.LI.24.L.G 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, resistance 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.L.G 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. -

Page 14: Figure 7. Fastening Screw Lock Protection In The Li-24G Transmitter
EN.IO.LI.24.L.G The head-mounted transmitter LI-24G is equipped with fastening screw lock protection in the form of locks in the mounting holes. The lock is suitable for use with screw threads, and therefore the screws must be screwed into the transmitter housing. Pushing the fastening screws into the mounting holes instead of screwing them in may damage the screw lock protection. -

Page 23: Configuration Of The Operating Mode
The design of the transmitter allows detection of many dangerous failures. In addition to the diagnos- tics signalled with alarm current and the diagnostics being readable by via digital HART communica- tion, the LI-24L transmitter is equipped with a two-colour LED indicator which signals the operating status of the device. - Page 24 EN.IO.LI.24.L.G − measurement average: 0,5 ∙ (Ch1+Ch2); − measurement average with redundancy: 0,5 ∙ (Ch1+Ch2) or Ch2 or Ch1, when one of the sensors is damaged. Redundancy corresponds to the following variants of the sen- sors connection: 2 x RTD 2-wire connection, 2 x RTD 3-wire connection, 2 x thermo- couple, 2 x thermocouple with external CJC (alarm deactivation is required);...
