LRV
"Lower Range Value" –the value of the set range expressed in physical units corresponding to the current
of 4,000 mA, i.e. 0% of the output setpoint. The set range cannot exceed the set range limits. The minimum
width of the set range |(URV-LRV)| is limited to 10% of the base range (URL-LRL).
2
URV
"Upper Range Value" –the value of the set range expressed in physical units corresponding to the current
of 20,000 mA, i.e. 100% of the output setpoint. The set range cannot exceed the set range limits. The
minimum width of the set range |(URV-LRV)| is limited to 10% of the base range (URL-LRL).
3
LRL
LSL
"Lower Range Limit" or "Lower Sensor Limit" - lower limit of set range expressed in physical units. Value
(URL-LRL) or (USL-LSL) is referred to as the base transmitter range.
4
URL
USL
"Upper Range Limit" or "Upper Sensor Limit" –upper limit of set range expressed in physical units. Value
(URL-LRL) or (USL-LSL) is referred to as the base transmitter range.
5
LPL
"Lower Processing Limit" –lower limit of digital processing of measured value. The transmitter processes a
digital measurement up to 50% of the base range width below the lower limit of set range LRL (LSL). After
reaching the LPL and when below this value up to LSAL, the transmitter freezes the refreshing of digital
value of the measurement.

6. INSTALLATION
6.1. General recommendations
It is recommended that in case of a gaseous medium, the transmitters should be installed
above the measuring point so that condensate may flow to the point from which the meas-
ured pressure is collected, while in case of liquid medium or steam, it should be installed
below the point of pressure intake.
For low measurement ranges, there may be an influence of transmitter's position and influence of im-
pulse lines position and liquid filling method on output signal. Any possible misalignment of the signal
should be corrected by resetting the transducer after mounting ➔8.3.
6.1.1. Installation instructions for transmitters with distance separators
The protection of the separator diaphragm can only be removed shortly before installation. Hydrostatic
pressure of the manometric liquid column in the transmitter-separator system may cause incorrect in-
dication of the measured value. After installation, the transmitter must be pressure-reset.
Do not clean or touch separator diaphragms using hard or pointy objects.
Separators with pressure transmitter form a closed, calibrated system filled with gauge
fluid. The opening for filling the device with gauge fluid is sealed and must not be opened.
When choosing a mounting location, it is necessary to ensure sufficient stress relief of the
capillaries tension in order to avoid excessive bending.
Incorrect installation of the sealing may result in incorrect measurement indications.
Special attention must be paid when selecting correct dimensions of the sealing.
As standard, the separators are not provided with the gaskets.

7. ELECTRICAL CONNECTION
7.1. Cable connection to transmitter internal terminals
All connection and installation operations shall be performed with disconnected supply volt-
age 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.
7.1.1. Connection of transmitters with PD type connector
Loosen the screw in the upper part of the connector and the nut that connects the connector to the
transmitter housing, the cable outlet can be set in any direction. It is advantageous to form the conduit
in the form of a drip loop to prevent condensation from running down towards the gland. Connect the
cables in accordance with the marking on the transducer and Table 3 (depending on the version).
A correctly assembled PD connection should have tightened: the gland nut, the connection nut to the
steel housing and the screw connecting both parts of the connector.
7.1.2. Connection of transmitters with PZ type connector
The electrical connection of the transmitters with the connector should be made by connecting the
signal wires to the transmitter terminals. Screw on the cover and the stuffing plug of the gland care-
fully, making sure that the gasket is tightly compressed on the conduit.
7.1.3. Connection of transmitters with PK, PKD, SG and PM12 type connector (cable
connection)
Electrical connections of transmitters equipped with PK, PKD, PM12 type connectors are made
through a terminal box with a gland in which the converter cable connects to the further part of the
signal line. The terminal box must not be completely airtight, as the transmitter must be able to
“breathe” through a capillary in the connector cable.

7.1.4. Connection of transmitter with the option of using local HART communication
The transmitter allows to use the local HART communication. To do this you can use a HART commu-
nicator unit or modem connected to a computer or a smartphone.
In order to communicate with the intelligent transducer (via the HART protocol), before
connecting the local communicator or modem, check if the Ro resistance, seen from the
transducer terminals towards the power source, is Ro ≥240 Ω.
Figure 2. Electrical connection 4…20 mA of HART to transmitter in standard version.
The converter may also be operated using Aplisens Mobile Configurator installed on smartphones
with Android system and connected using wireless communication.
The software is available on Google Play®
https://play.google.com/store/apps/details?id=com.aplisens.mobile.amc
7.1.5. Cabling specification
Aplisens S.A. recommends using two-wire screened twisted pair cable. The outer diameter of the cable
shell from 6to 9 mm(forcable gland PG-9) or from8 to 10 mm(for cable gland PG-11) is recommended.
7.2. Earthing
Transmitters with PD connections have a ground terminal in the connector, which should not be used
for protective groundingor for connecting the equalizing conductor; it is only used for functional ground-
ing. The transmitters withPZ connection are equipped with internal (inEx version also external) ground-
ing terminals, to which functional or equipotential grounding conductors can be connected. In transmit-
ters with PK, PKD, SG, PM12 cable connections, the cable screens are brought out and remain at the
user's disposal. The screen of the cable should be connected on one side with the earthing point of the
measuring system.
If the transmitter has a galvanic connection via the process connection to a well-grounded metal pipe
or vessel, additional functional grounding is not necessary. The grounding terminals in electrical
connections are as functional grounding. They should be used when the transmitter is not grounded
through the head connection stub. If it is impossible to ground the cable shield at the power supply point
and the converter grounded through the head connector, the grounding clamps can be used to connect

EN.IO.PCE.PRE.28.SMART
Revision 01.A.001/2021.10 13
the cable shield. Functional grounding is to ensure the correct operation of the anti-interference sup-
pression unit of the transmitter. In standard installations, i.e. when the transmitter is grounded through
the pipeline, and the possible cable shield is connected to the transmitter's power supply and measure-
ment system, the functional grounding terminal should not be used.
7.3. Overvoltage protection
Transducers may be exposed to oversea or lightning. Surge protection between transmission line ca-
bles is provided by transil diodes installed in all types of transducers.
In order to protect against surges between the transmission line and the ground or housing (which are
not protected by diodes connected between the line lines), additional protection in the form of surge
gas stops shall be applied. In addition, an external protective device such as the APLISENS UZ-2
system or other.
7.4. Shielding
In the case of using a cable in the screen, connect the screen on one side at the point where the
transmitter is powered.
7.4.1. Uninterruptible current measurement in 4…20 mA current loop
The transmitter is capable of continuous current measurement in the current loop using an ammeter. In
order to maintain the current measurement error below 0,05%, the internal resistance of the ammeter
shall be less than 10 Ω.
7.4.2. Specifications of electrical switching terminals
Internal electrical switching terminals are suitable for conductors with the cross-section from
0,5 to 2,5 mm2.
7.5. Equipotential bonding
In the case of using a cable in the screen, connect the screen on one side at the transmitter’s power
supply point.
The transmitter in intrinsically version should be powered from a galvanically separated power source
or, if this is not possible, equipotential bonding of the transmitter and the power supply device should
be ensured by means of equipotential bonding conductors. In this respect the locally applicable regu-
lations must be observed.
7.6. Transmitter power supply
Power cables may be live.
There is a risk of electric shock and/or explosion.
Installation of the transmitter in explosion-risk atmospheres must comply with national
standards and regulations.
All explosion protection data is given in appendix.

7.6.1. Resistance load in power supply line
The power line resistance, power source resistance and other additional serial resistances increase the
voltage drops between the power source and the transmitter terminals. The maximum current of stand-
ard transmitters under normal operation conditions is defined as I_max = 20,500 mA , but during high
alarm the value of current is defined as I max = 22,000 mA.
The maximum resistance value in the power circuit (along with the power cables resistance) is defined
by the formula:
where:
Usup –voltage at the supply terminals of the 4…20 mA current loop [V].
Umin –minimum supply voltage of transmitter.
7.7. 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 internal terminals)?;
−Are all the screws tightened? (depending of version);
−Are the transmitter covers tightened? (depending of version);
−Are the cable gland and the gland plug tightened? (depending of version).

8. START-UP
The base range and the basic unit of the transmitter can be read out from its nameplate (➔Transmitter
identification).
Use the transmitter within the allowable pressure limits. Risk of injury due to component break-
age after exceeding the maximum permitted operating pressure.
8.1. Alarm configuration
Transmitters has a developed internal diagnostics, which monitors the work of their electronic circuits,
process and environmental parameters. For transmitters in standard or Exi version, diagnosed danger-
ous states or malfunctions of the internaltransmitter systems result in setting the alarm current depend-
ing on the configuration I_AL<3,600 mA or I_AL>22,000 mA. The user has an option of enabling/disa-
bling of the current alarms. Current alarms are disabled by default. The figures below shows the normal
operation ranges of the transmitter process output and the ranges of saturation and alarm currents.
Figure 3. Set range current, saturation currents, alarm currents of transmitters in standard or Exi version.
1 - Set 4…20 mA current area is corresponding to setpoint 0...100% of the process output.
2 - Lower saturation current of 3,800 mA for NAMUR mode.
3 - Lower saturation current of 3,900 mA for NORMAL mode.
4 - Upper saturation current of 20,500 mA for NAMUR and NORMAL mode.
5 - Alarm current area AL_L<3,600 mA for internal diagnostic alarms.
6 - Alarm current area AL_H>22,000 mA for internal diagnostic alarms.
8.2. Configuration of operating mode
Before starting the work with the transmitter, the following parameters must be configured:
−basic unit of transmitter;
−processing characteristics;
−the beginning of the set LRV range;
−the end of the set URV range;
−damping time constant;
−NORMAL/NAMUR analogue output operation mode;

EN.IO.PCE.PRE.28.SMART
16 Revision 01.A.001/2021.10
−analog output operation mode in alarm status AL_L/AL_H (applies to transmitters in standard or
Exi version);
−alarm mode for indicating environmental events and defects;
−transmitter tag (TAG/LONG_TAG);
−setting of the settings change lock password.
8.3. Correction of impact of transmitter mounting position on site –pressure reset
Once the transmitter is mounted in a target location, it must be reset. This operation will eliminate the
possible influence of the mounting position on the indication of pressure/differential pressure. In order
to do so:
−in case of relative pressure transmitter without pressure supplied (vented), perform the pressure
reset operation using the local MENU or HART communication;
−in the case of a differential pressure transmitter, at compensated pressures on the L and
H supply, perform the pressure reset operation by means of local MENU or HART communica-
tion;
−in case of absolute pressure transmitter the resetting is only possible with an absolute pressure
calibration device. Otherwise an attempt to reset the transmitter will display an error.
9. OPERATION
9.1. Remote configuration of setpoints (HART 5/HART 7)
The transmitter allows to read out and configure the parameters via HART communication using 4...20
mA loop as a physical layer for FSK BELL 202 modulation.

10. MAINTENANCE
10.1.Periodic inspections
Periodic inspections shall be carried out in accordance with applicable standards. During the inspection,
the condition of the pressure (absence of loosened elements and leaks) and electrical (check of con-
nections reliability and condition of gaskets andglands) connectors, condition of separating diaphragms
(tarnish, corrosion) and stability of fixing of the housing andmounting bracket (if used) shall be checked.
Check the processing characteristics by performing the operations specific for the CONFIGURATION
procedure.
10.2.Non-periodic inspections
If the transmitter at the installation site has been exposed to mechanical damage, pressure overload,
hydraulic pulses, overvoltage, deposits, medium crystallization, undercutting of the diaphragm, or in-
correct operation of the transmitter is detected, the device should be inspected. Check the condition of
the diaphragm, clean it, check the electrical functionality of the transmitter and the processing charac-
teristics.
If there is no signal in the transmission line or its value is improper, check the supply line,
connection status on terminal blocks, connectors, etc. Check if the supply voltage and load
resistance are correct.
10.3.Cleaning/washing
To remove impurities from the external surfaces of the transmitter wipe it with a cloth dampened in
water.
10.3.1. Diaphragm cleaning
The only possible method of cleaning the transmitter diaphragms is to dissolve the sludge produced.
Do not remove deposits and impurities from the transmitter diaphragms, which are
formed during operation, mechanically using tools, since the diaphragms and the trans-
mitter can be damaged.
10.4.Spare parts
Parts of the transmitter that may be worn or damaged and thus replaced:
−Transmitters with PD connector: terminal block with angular cover and gasket, and connect or
base with gasket;
−In the transmitter with PK, PKD connection - all connections;
−In the transmitter with PZ connector - cover gasket and gland, electrical connection plate with
a cover;
−In the transmitter with PM12 connection - PM12 connector;
