Meaning
1
LRV
"Lower Range Value" –the value of the set range expressed in physical units corre-
sponding 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 corre-
sponding 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 digitally processes a measurement up to 50% of the base range width be-
low 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 meas-
urement.
6
UPL
"Upper Processing Limit" –upper limit of digital processing of measured value. The
transmitter digitally processes a measurement up to 50% of the base range width
above the upper limit of set range URL (USL). After reaching the UPL and when above
this value up to USAL, the transmitter freezes the refreshing of digital value of the
measurement.
7
LSAL
"Lower SaturationLimit" - lower limit of the A/D transmitter processingrange. The lower
limit of the A/D transmitter saturation is on the pressure / differential pressure scale
below the LPL point and is associated with the minimum pressure, at which the ana-
logue-digital pressure measurement transmitter reaches the lower limit of the pro-
cessing capacity. The exact determination of this pressure is not possible, however
usually the pressure does not exceed the pressure corresponding to 200% of the base
range width (URL-LRL) below the lower limit of the digital processing of measured LPL
value.
8
USAL
"Upper Saturation Limit" - upper limit of the A/D transmitter processing range. The up-
per limit saturation point of A/D transmitter is on the pressure / differential pressure
scale above the UPL point and is associated with the maximum pressure at which the
analogue-digital pressure measurement transmitter reaches the upper limit of the pro-
cessing capacity. The exact determination of this pressure is not possible, however
usually the pressure does not exceed the pressure corresponding to 200% of the base
range width (URL-LRL) above the upper limit of the digital processing of measured
UPL value.

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. The configuration of impulse tubes and valve connec-
tion system should be selected taking into account the measurement conditions.
For low measurement ranges, there may be an influence of transmitter's position and influence of
impulse lines position and liquid filling method onoutput signal. Any possible misalignment of the signal
should be corrected by resetting the transducer after mounting (➔8.3. Correction of impact of trans-
mitter mounting position on site –pressure reset).
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 indication 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
voltage 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
In order to properly connect the wires, unscrew and remove the terminal block with its cover from the
contact pins. Remove the block from the cover, undermining it with the end of the screwdriver inserted
into the slot provided for this purpose. Connect the wires to the cube as shown in the picture below.
Rotation of the electrical connector by 90º realize by appropriately mounting the terminal block in the
cover of connector. It is advantageous to form the conduit in the form of a drip loop to prevent conden-
sation from running down towards the gland.
Figure 2. Electrical connection of transmitter with PD connection
7.1.2. Connection of transmitters with PZ-type connector
The electrical connection of the transmitters should be made by connecting the signal wires to the
transmitter terminals. Screw on the cover and the stuffing plug of the gland carefully, making sure that
the gasket is tightly compressed on the conduit. There is a terminal block installed inside equipped with
additional control terminals connected to terminals 1, 2, 3.

7.1.3. Connection of transmitter with the option of using 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. For more information on communication, see ➔9. OP-
ERATION.
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.

7.2.2. 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 or Exi transmitters under normal operation conditions is 20,500 mA, but during high alarm the value
of current I_max is 22,000 mA.
The maximum resistance value in the power circuit (along with the power cables resistance) is defined
by the formula:
𝑅𝑂𝑚𝑎𝑥[Ω]=(𝑈𝑧𝑎𝑠 − 𝑈𝑃𝑚𝑖𝑛)[𝑉]
0,0225[𝐴]
where:
Uzas –voltage at the supply terminals of the 4 … 20 mA current loop [V].
UPmin –minimum supply voltage of the transmitter ➔7.2.1. Transmitter supply voltage.
7.2.3. Uninterruptible current measurement in 4 … 20 mA current loop
The transmitter with PZ connector 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 re-
sistance of the ammeter shall be less than 10 Ω.
7.2.4. Specifications of electrical switching terminals
Internal electrical switching terminals are suitable for conductors with the cross-section from
0,5 to 2,5 mm2.
7.2.5. Cabling specification
Aplisens S.A. recommends using two-wire screened twisted pair cable (connect the screen on one side
at the point where the transmitter is powered).

EN.IO.APCE.APRE.2000
14 Revision 01.A.001/2023.09
7.3. 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 with PZ connection are equipped with internal (in Ex version also external) ground-
ing terminals, to which functional or equipotential grounding conductors can be connected.
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
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.
7.4. Equipotential bonding
When using an intrinsically safe transmitter with an additional overvoltage protection, having the desig-
nation “SA version” on the plate, the transmitter 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
regulations must be observed.
7.5. Overvoltage protection
Transmitters in standard version are fitted with overvoltage protection. In addition, an external protec-
tive device such as the APLISENS UZ-2 system or other.
In intrinsically safe transmitters, in order to increase the resistance to excessive surge, it is possible to
use the overvoltage protection SA version. Transmitters with integrated overvoltage protection SA
should be connected in accordance with ➔7.4. Equipotential bonding.
7.6. 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 accordingto the information given in section ➔7.1. Cable connection
to transmitter internal terminals?
−Are all the screws tightened?
−Are the transmitter covers tightened?
−Are the cable gland and the gland plug tightened?

EN.IO.APCE.APRE.2000
Revision 01.A.001/2023.09 15
8. START-UP
As standard, the transmitter is adjusted to a set range equal to the base range, unless a specific set
range is provided in the order. The base range and the basic unit of the transmitter can be read out
from its nameplate (➔5.2. Transmitter identification).
The transmitter should be use within the allowable pressure limits. Risk of injury due to
component breakage after exceeding the maximum permitted operating pressure.
The working position of APCE(RE)-2000 transmitters (except APRE-2000G) can be any. For lowmeas-
uring ranges, the position of the transmitter and the method of laying and filling the impulse lines with
liquid affect the indications. This error can be corrected by performing a reset after installation.
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 currentdepend-
ing on the configuration I_AL < 3,600 mA or I_AL > 22,000 mA. The user has an option of enabling/dis-
abling of the current alarms. Current alarms are disabled by default.
The figure below shows the normal operation ranges of the transmitter process output and the ranges
of saturation and alarm currents.
Figure 5. 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.

EN.IO.APCE.APRE.2000
16 Revision 01.A.001/2023.09
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;
−analogue output operation mode in alarm status AL_L/AL_H;
−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.

Revision 01.A.001/2023.09 17
9. OPERATION
9.1. Remote configuration of setpoints (HART)
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.
9.2. 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 interoperating with a computer or a smartphone. In order to establish communi-
cation, it is necessary to connect the communicator or modem to terminals.
9.3. Compatible configuration software
−Raport 2 Aplisens under control of Windows 7 or Windows 10.
−Aplisens Mobile Configurator under control of the Android system.
−Every software from other companies accepting DDL and DTM libraries.
9.4. Compatible devices
The following devices may be used to communicate with the transmitter:
−Aplisens S.A. KAP-03, KAP-03Ex communicator.
−Communicators from other companies, including those using DDL and DTM libraries.
−PC computers equipped with HART modem (e.g. HART/USB converter by Aplisens S.A.) with
Windows7 or Windows10 operating system with installed Raport 2.
−PC computers equipped with HART modem using software from other companies, accepting
DDL and DTM libraries.
−Smartphones with Android system, using a converter providing wireless communication (e.g.
HART/USB converter by Aplisens S.A.) using Aplisens Mobile Configurator. The software is
available on Google Play under the link:
https://play.google.com/store/apps/details?id=com.aplisens.mobile.amc.
9.5. Method of connecting communication devices
The method of connecting communication devices locally to the transmitter is described in section
➔7.1.3. Connection of transmitter with the option of using HART communication. For remote commu-
nication, the HART modem should be connected in parallel to the 4 … 20 mA line. The resistance
between the power supply and the modem connection point must be greater than 240 Ω. It is also
required to observe the guidelines on the minimum load resistance RL_MAX described in section
➔7.2.2. Resistance load in power supply line.When using measuring cards with a built-in HART mas-
ter, it is necessary to observe the instructions provided by the card manufacturer.

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 and glands) connectors, condition of separating diaphragms
(tarnish, corrosion) and stability of fixing of the housing and mounting bracket (if used) shall be checked.
Check the processing characteristics by performing the operations specific for the CALIBRATION and
possibly 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 thetransmitter diaphragms, which are formed
during operation, mechanically using tools, since the diaphragms and the transmitter can
be damaged.
10.4. Spare parts
Parts of the transmitter that may be worn or damaged and thus replaced:
−Transmitter with PD connector: terminal block with angular cover and gasket, connector base with
gasket;
−Transmitter with PZ connector: cover gasket and gland, electrical connection plate with a cover.
Other parts in the case of ATEX, PED type of transmitter may be replaced only by the
manufacturer or an authorized representative.
10.5. Repair
Faulty or non-operational transmitter shall be provided to the manufacturer.
10.6. Returns
In the following cases, the transmitter should be returned directly to the manufacturer:
−need for repair;
−need for factory calibration;
−replacement of improperly selected/shipped transmitter.
