1. 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.
The manual does not cover explosion protection issues.
Reading the SIL EN.IB.LI.24.ALW.SFT safety manual is mandatory, as it contains
detailed data about the transmitter operation in the functional safety loop.
The use of the equipment in hazardous zones without appropriate approvals is forbidden.
It is mandatory to read EN.IX.LI.24.ALW Explosion-proof Device User Manual, containing
important information related to the installation of intrinsically safe version of the transmit-
ters.

Meaning
1
LRV
“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. The
minimum width of the set voltage range |(URV-LRV)| is limited by software to 10°C for resistive
sensors (10 Ω for resistance measurement) or 50°C for voltage type sensors (10 mV for voltage
measurement).
2
URV
“Upper Range Value” — the value of the set range expressed in the units of temperature,
resistance or voltages corresponding to the current of 20,000 mA, i.e. 100% of the output set-
point. The set range must not exceed the set range limits which depend on the selected meas-
urement type. The minimum width of the set voltage range |(URV-LRV)| is limited by software
to 10°C for resistive sensors (10 Ω for resistance measurement) or 50°C for voltage type sen-
sors (10 mV for voltage measurement).
3
LRL
LSL
“Lower Range Limit” or “Lower Sensor Limit” – the lower limit of the set range expressed in the
units of temperature, resistance or voltage. Value (URL-LRL) or (USL-LSL) is referred to as
the transmitter base range and depends on the selected measurement type.
4
URL
USL
“Upper Range Limit” or “Upper Sensor Limit” – the upper limit of the set range expressed in
the units of temperature, resistance or voltage. Value (URL-LRL) or (USL-LSL) is referred to
as the transmitter base range and depends on the selected measurement type.
5
LPL
“Lower Processing Limit” – the lower limit of digital processing of the measured value. The
transmitter digitally processes the measurement below the lower limit of the LRL/LSL set
range. When LPL is reached, the transmitter freezes digital value measurement refreshing and
the diagnostic alarm mode I_AL<3,600 mA is activated. In addition, collective statuses of the
transmitter will be set: “Sensor error”, “First Process Variable Calculation Error”, “First Process
Variable out of Range” and “Second or Subsequent Process Variables out of Range”. These
can be read out in the diagnostic tab via the HART communication.
6
UPL
“Upper Processing Limit” – the upper limit of digital processing of the measured value. The
transmitter digitally processes the measurement up to the upper limit of the URL/USL set
range. When UPL is reached, the transmitter freezes digital value measurement refreshing
and the diagnostic alarm mode I_AL<3,600 mA is activated. In addition, collective statuses of
the transmitter will be set: “Sensor error”, “First Process Variable Calculation Error”, “First Pro-
cess Variable out of Range” and “Second or Subsequent Process Variables out of Range”.
These can be read out in the diagnostic tab via the HART communication.

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.
