6. CONSTRUCTION
6.1. Construction
The basic transducer assemblies are the housing and the electronic assembly converting the signal
from the measuring sensor into a unified output signal. The electronics main board with display is
placed in a polycarbonate cover. This assembly is located in a larger housing chamber, where it can
be rotated ±180° every 90°. This allows you to change the position of the display. In the second cham-
ber there is a connecting plate, also protectedby a polycarbonate-nu cover, with connection terminals.
6.2. Measurement principle
Signal from the measuring sensor, i.e. thermometric resistor or measuring junction of the thermocou-
ple, corresponding to the measured temperature of the medium, is sent to the input of the analogue-
digital transmitter and converted to digital signal. The digital signal is sent via the optoelectronic gal-
vanic barrier to the main board. Microcontroller of the main board reads the measured values and
uses the incorporated algorithms to calculate the precise temperature. Theresulting value isdisplayed
on the integrated LCD display which can be configured according to the user’s needs . Digital value
of the measured temperature is converted to analogue signal of 4...20 [mA]. The integrated modem
BELL 202 and the implemented communication stack, HART rev 5.1, enable communication with the
transmitter via converter connected to a PC computer and appropriate software or via communicator.
The transmitter is provided with an output interference filter and overvoltage protection components.
Fig. 1 shows the block diagram of the transmitter. LI-24ALW transmitter monitors its hardware re-
sources and calculation accuracy. In case of a failure the transmitter specifies an error code on the
LCD display and generates alarm current in the current loop. Measuring signal from the sensor is
isolated galvanically from the current line. As a result the transmitter is less susceptible to interference
and provides better safety of work in intrinsically safe applications.

7. INSTALLATION
7.1. General recommendations
Temperature transmitter LI-24ALW can be mounted in any position.
The housing of the transmitter should be protected against hot air streams by appropriate location
of the transducer or by installing thermal screens so that the transmitter does not heat up to a temper-
ature higher than the permissible one. The transmitter housing allows for wall and pipe mounting. For
this purpose, use the AL handle by Aplisens S.A.
8. ELECTRICAL CONNECTION
8.1. Cable connection to transmitter terminals
All connection and installation operations must beperformed with disconnected supplyvoltage
and other external voltages, if used.
Failure to provide proper connection of the transmitter may result in danger.
Risk of electric shock and/or ignition in potentially explosive atmospheres.
8.1.1. Cable connection
In order to perform correct connection of the cables, the following steps shall be performed:
−disconnect power supply of the supply cable line before connecting the transmitter cabling;
−unscrew the rear cover of the transducer body in order to gain access to the power supply,
measurement terminals and the internal ground terminal;
−4...20 mA current loop power supply and signal cables should be properly connected to the "+",
"-" terminals;
−connect the transmitter in accordance with figures below and section ➔8.1.2, paying attention
to the correct tightening of the screws fixing the conductor core to the terminal;
−depending on the type of installation grounding adopted, connect the shield of the cable to the
earth screw terminal of the body;
−leaving a slight slack in the cable inside the body, tighten the glands nut so that the gland seal
tightens on the power cable.

8.3.2. Specifications of electrical switching terminals
The internal electrical connection terminals accept wires with a cross section of 0.5 to 1.75 mm2.
Internal and external electrical terminal of the body ground accepts wires with a cross-section from 0.5
to 4 mm2 .
Possible cables to be used:
-unshielded when using the analogue signal only;
-shielded, approved for the HART communication;
-shielded on the sensor(s) side for a cable length greater than 30 m or over-normative radio
interference.
8.3.3. Resistance load in power supply line
The power line resistance, power source resistance and other additional resistances connected
in series increase the voltage drops between the power source and the transmitter terminals. The max-
imum transmitter current under normal operation conditions is defined as I_max = 21,600 mA (the max-
imum possible current value issued by the user is 23,00 mA).
The maximum resistance value in the power circuit (along with the power cables resistances)
is defined by the formula:
where:
Usup –voltage at the supply terminals of 4…20 mA current loop [V].
Umin –minimum supply voltage.
RLmax –maximum power line resistance [Ω].
8.3.4. Shielding, equipotential bonding
Optimal protection against interference is provided by the earthing of the screen on both sides.
In case of potential difference between earthing points of devices which may result in the flow of equi-
potential currents, the screen shall be earthed on one side.
8.4. Final inspection of cabling
After completing the electrical installation of the transmitter, it is necessary to check the following:
-does the supply voltage measured at the transmitter terminals at maximum set current match
the range of supply voltage specified on the transmitter nameplate;
-Is the transmitter connected according to the information given in section (➔Cable connection
to transmitter terminals);
-Are all the screws tightened;
-Are the cable terminals tightened;
-Is the cable gland tightened.

9. START-UP
Upon request, the customer receives a transmitter configured according to the setpoints specified
in the order.
The current base range and the basic unit of the transmitter can be read out from the device via the
HART communication.
9.1. Alarms
The alarms signal hardware faults, calculation errors or exceeding the permissible operating ranges of
the transmitter. Internal hardware faults include e.g. RAM and FLASH memory failures, damage to the
internal oscillator, opto-isolation interface, ADC measurement converter, internal HART modem. Exter-
nal malfunctions are related to damage or improper connection of measurement sensors to the trans-
mitter. Transmitter operating temperature ranges are exceeded.
The errors are manifested by the transmitter issuing an alarm current in the line and signalling an error
code on the display. The alarm current values can be set using the program Raport 2 or by ordering an
appropriate alarm configuration in the transmitter from the supplier.
Temperature transmitters LI-24ALW manufactured by Aplisens meet the alarm require-
ments Namur NE 89 and Namur NE 43.

9.2. Configuration of the operating mode
Before starting the work with the transmitter, the following parameters must be configured:
-basic unit of the transmitter process variable;
-measurement input type (voltage/resistance);
-measurement sensor processing characteristics (selection of sensor linearization characteris-
tics);
-measurement sensitivity range (100 mV/1000 mV or 400 Ω/2000 Ω);
-type of sensor connections, number of terminals, CJC configuration (internal, external
or none);
-type of the mathematical function processing the signal from two sensors (2 x RTD 2-wire con-
nection, 2 x RTD 3-wire connection, 2 x thermocouple, 2 x thermocouple with external CJC (see
➔Figure 2. Methods of connecting sensors, potentiometers and voltage sources.)):
-difference of measurements from channels: Ch1-Ch2 or Ch2-Ch1;
-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 thermocou-
ple, 2 x thermocouple with external CJC (alarm deactivation is required);
-minimum value of the two measurements: min (Ch1, Ch2);
-maximum value of the two measurements: max (Ch1, Ch2).
In case of using the configuration with linearization, shorting one of the sensors
results in triggering an alarm. This is due to the measurement going beyond the linear-
ization table. In non-linearization configurations with resistance sensors, short
circuits are undetectable;

EN.IO.LI.24.ALW

10. OPERATION
The programmable display is designed to shows the values measured during the
measurement process. These can be process variables of the measured temperature, current in the
current loop or other values converted from the process current variable to the user's units.
10.1. Display configuration
The user can change some transmitter settings, including the display using the buttons below the
display. The buttons can be accessed by unscrewing the display cover. The buttons are marked with
symbols: [↓], [↑] and [●].
The buttons [↓], [↑] are used to move up and down the MENU structure, and the button [●] confirms and
executes the selected option. Pressing and holding any button for about 4 seconds will cause enter to
the local setting mode, and the following message “EXIT” appears on the display in the field LCD3. No
activity in the MENU area for longer than 2 minutes automatically exits the local setting mode and goes
to display process variable. After confirming the selected parameter, the display will confirm the ac-
ceptance of the command with a "DONE" message. The "← BACK" button allows to move up a level
higher in the MENU structure.
The way of navigating in the MENU structure of the local display is shown in the diagram below.
