Meaning
1
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 20.000mA, 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. In this situation, message “UndEr” will
be displayed on the display and diagnostic alarm mode will be activated depending on the set-
tings I_AL < 3.650 mA or I_AL > 21.500 mA. Additionally, collective status PV_OUT_OF LIMITS
and status PV_LOW_LIMITED in the Transducer Block will be set, which can be read out in the
diagnostic tab via HART communication.
6
UPL
“Upper Processing Limit” – upper limit of digital processing of measured value. The transmitter
processes a digital 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 transmit-
ter freezes the refreshing of digital value of the measurement. In this situation, message "OvEr"
will be displayed on the display and diagnostic alarm mode will be activated depending on the
settings I_AL< 3.650 mA or I_AL > 21.500 mA. Additionally, collective status PV_OUT_OF LIM-
ITS and status PV_HIGH_LIMITED in the Transducer Block will be set, which can be read out in
the diagnostic tab via HART communication.
7
LSAL
“Lower Saturation Limit” – lower limit of the A/D transmitter processing range. 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 analogue-digital pressure measure-
ment transmitter reaches the lower limit of the processing capacity. The exact determination of
this pressure is not possible, however usually the pressure does not exceed the pressure corre-
sponding to 200 % of the base range width (URL-LRL) below the lower limit of the digital pro-
cessing of measured LPL value. After reaching LSAL and when below this value, error number
E0256 will be displayed and the diagnostic alarm mode will be activated depending on the set-
tings I_AL < 3.650 mA or I_AL > 21.500 mA. Additionally, collective status SENSOR_FAULT,
PV_OUT_OF LIMITS, status NOREF+ERR@AIN1_AD7794 in the Sensor Block and
PV_LOW_LIMITED in the Transducer Block will be set, which can be read out in the diagnostic
tab via HART communication.

PL.IO.APREGN
6 Revision.02.A.002
8
USAL
“Upper Saturation Limit” – upper limit of the A/D transmitter processing range. The upper 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 processing capacity. The exact determi-
nation of this pressure is not possible, however usually the pressure does not exceed the pres-
sure corresponding to 200% of the base range width (URL-LRL) above the upper limit of the
digital processing of measured UPL value. After reaching USAL and when above this value,
error number E0256 will be displayed and the diagnostic alarm mode will be activated depending
on the settings I_AL < 3.650 mA or I_AL > 21.500 mA. Additionally, collective status SEN-
SOR_FAULT, PV_OUT_OF LIMITS, status NOREF+ERR@AIN1_AD7794 in the Sensor Block
and PV_HIGH_LIMITED in the Transducer Block will be set, which can be read out in the diag-
nostic tab via HART communication.

1.4. Transmitter set range
The figure below shows the transmitter set range and limits related to allowable set range, digital pro-
cessing range and saturation limits of A/D pressure measurement transducer. As standard, values of
4 mA/20 mA currents 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.

The basic transmitter assemblies are: housing, processing unit (with pressure sensor and electronic
unit), in which the pressure signal is converted into an electric signal and transformed into a unified
output signal.
6.1. Transmitter housing and dimensions
The APRE-2000GN transmitter housing is made of polycarbonate –PC or ABS and consists of a
housing body and a transparent cover to ensure the readability of the LCD display.
The housing body is equipped with pressure connections for plastic tubes Ø6x1 and electrical con-
nection.
On the inner side surface of the housing body there is an anti-interference filter unit electrically con-
nected to the processing unit and to the base of the electrical connection of the transmitter.

Revision.02.A.002 11
7. INSTALLATION
7.1. 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
measured pressure is collected. The configuration of impulse tubes and valve connection
system should be selected taking into account the measurement conditions.
Differential pressure transmitters for gases APRE-2000GN should be obligatorily installed
vertically.
7.2. Installation and pressure connection
The APRE-2000GN transmitters can be mounted on a wall or on a control panel.
The installation method is shown in Fig. 4.
The transmitter is fitted with connectors which fit to a Ø6x1 elastic impulse tube.
In case of significant level differences between the transmitter location and the pulse point, a ‘’floating’’
effect of the measurement may occur when the temperature difference of the impulse tubes changes.
This effect can be reduced by leading the impulse tubes side by side.
When assembling transmitter mounting accessories, information about connecting pressure elements
such as: reductive, nests, valves, reducer clamps, signal tubes –offered by APLISENS –may be help-
ful. Data on this subject are contained in catalogue.

8.2.2. 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 transmitter
current 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 de-
fined by the formula:
RL_MAX [Ω] ≤=
where:
U –voltage of 4…20 mA current loop power supply unit in [V];
RL_MAX –maximum power supply line resistance in [Ω].

ER_L07
message displayed on LCD3. It is displayed if a user tries to change the setpoint in the transmitter pro-
tected against entry (change of setpoints).
ER_L09
message displayed on LCD3. It is displayed if:
a user tries to change the set range by set pressure which is not within the allowable upper
URL pressure.
A user tries to reset pressure when the pressure exceeds the allowable upper limit.
ER_L10
message displayed on LCD3. It is displayed if:
a user tries to change the set range by set pressure which is not within the allowable lower LRL
pressure.
A user tries to reset pressure when the pressure exceeds the allowable lower limit.
ER_L14
message displayed on LCD3. It is displayed if:
the adopted URV value through the set pressure or entry of a value cannot be accepted be-
cause it causes a reduction of the set pressure range set below the allowable limit.
ER_L16
message displayed on LCD3. It is displayed if:
a user tried to perform an operation that is disabled or unavailable. It may be caused by:
attempting to access the local setpoint change MENU when
the access to the local MENU is disabled;
attempting to reset pressure in the absolute pressure measurement transducer.

EN.IO.APREGN
Revision.02.A.002 17
WG_L14
the message will appear if the assumed LRV value through the set pressure or entry of a value causes
a decrease of the current set range. Entry of LRV automatically results in the transmitter’s attempt to set
URV in such a way that the current width of the set range is maintained. If this is not possible due to
exceeded URL, the transmitter automatically adopts the URV = URL and a new LRV. Since the set
range width and URV deviate from previous values, a message is displayed.
ASCII characters displayed on LCD3 in user’s unit:
using HART communication, the user can configure its own 6-character unit displayed on
LCD3. It is possible to display ASCII characters from the range (32 ... 96 dec) or
(20 … 60 hex), i.e.:
!"#$%&'()*+,-./0123456789:;<>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`
9.2. Local buttons

gate through MENU and accept MENU options. The MENU can be accessed by pressing and holding
any of the buttons for at least 4 seconds. After this time, the LCD3 field of the local display will show
an EXIT message. This signals entering into the MENU navigation mode.
9.3. Local configuration of setpoint
APRE-2000GN transmitter enables local configuration of some of the most common setpoints via
local buttons and local LCD display.
9.4. Navigation in local setpoints MENU
The MENU can be accessed by pressing and holding any of the buttons for at least 4 seconds. After
this time, the LCD3 field of the local display will show an EXIT message. This signals entering into the
local configuration MENU. By pressing the buttons with arrows [↑] [↓] for at least 1 second you can
move up or down MENU.
9.5. Acceptance of local setpoints
The key marked with symbol [●] is used to accept the selection. The acceptance of setpoint change is
confirmed by a DONE message displayed on LCD3. After changing the setpoint, the transmitter
leaves the local configuration change MENU. If no selection is made in the MENU mode, after 2
minutes the transmitter automatically returns to display of standard messages. The MENU can also
be left by selecting and accepting the EXIT option.
9.6. Structure of local setpoints MENU
Press and hold any of 3 buttons for 4 seconds.
When navigating in the area of the active local MENU, holding the button required to trigger the action
is minimum 1 second. Continuous pressing of the ↑ or ↓ button results in scrolling of the MENU posi-
tions every 1 second. If the local MENU remains inactive for more than 2 minutes, after this time the
transmitter will automatically leave the local MENU and will display the process variable.

10. 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 (Transmitter identification).
Use the transmitter within the allowable pressure limits. Risk of injury due to component
breakage after exceeding the maximum permitted operating pressure.
10.1. Alarm configuration
Transmitter APRE-2000GN has a developed internal diagnostics, which monitors the work of elec-
tronic circuits, process and environmental parameters. Diagnosed dangerous states or malfunctions
of the internal transmitter systems result in setting the alarm current depending on the configuration
I_AL < 3.650 mA or I_AL > 21.500 mA. The user has an option of enabling/disabling 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 7. Set range current, saturation currents, alarm currents.
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 < 3.650 mA for internal diagnostic alarms.
6 –Alarm current area AL_H > 21,500 mA for internal diagnostic alarms.
