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. In this situation, for Exd (XP) or Exi/Exd version of transmitter, error number E0128 will be displayed on the display and diagnostic alarm mode I_AL < 3,600 mA will be set. For standard or Exi transmitters, a message ‘’UndEr’’ will be displayed, 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_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 transmitter freezes the refreshing of digital value of the measurement. In this situation, for Exd or Exi/Exd (also IS, XP, IS/XP) version of trans- mitter, error number E0128 will be displayed on the display and diagnostic alarm mode I_AL < 3,600 mA will be set. For standard or Exi transmitters, a message ‘’OvEr’’ will be displayed 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_LIMITS 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 measurement 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 corresponding to 200% of the base range width (URL- LRL) below the lower limit of the digital processing of measured LPL value. After reaching LSAL and when below this value, error number E0136 will be displayed on the display and the diagnostic alarm mode I_AL < 3,600 mA will be activated (applies to Exd or Exi/Exd (also IS, XP, IS/XP) version of transmitter). For standard or Exi transmitters, error number E0256 will be displayed 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 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.
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 associ- ated with the maximum pressure at which the analogue-digital pressure measurement transmitter reaches the upper limit of the processing capacity. The exact determination of this pressure is not possible, how- ever 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. After reaching USAL and when above this value, error number E0136 will be displayed on the display and the diagnostic alarm mode I_AL < 3,600 mA will be activated (applies to Exd or Exi/Exd (also IS, XP, IS/XP) version of trans- mitter). For standard or Exi transmitters, error number E0256 will be displayed 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 SENSOR_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 diagnostic tab via HART communication.
9| AL_L| Low current alarm.
10| AL_H| High current alarm.
11| I_AL| The alarm current set by the transmitter controller in the current loop.

1.4. Transmitter set range
The figure below shows the transmitter set range and limits related to allowable set range, digital processing 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.

INSTALLATION

6.1. General recommendations
In order to avoid measurement errors caused by the accumulation of condensate (in gas installations) or gas bubbles (in liquid installations) in impulse lines, assembly solutions using constructions based on available engineering knowledge should be used. For a gaseous medium, this may mean installing the transmitters above the pressure measuring point, and for liquids below this point. Differential pressure transmitters for gases APR2000ALW/G should be obligatorily installed vertically.

Figure 3. Examples of differential pressure transmitter installation

Figure 4. Examples of transmitter installation on tanks
6.1.2. 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.

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. Cable connection
In order to perform correct connection of the cables, the following steps shall be performed:

• disconnect power supply;
• unscrew the rear cover of the transmitter body to access the power connector;
•  pull the cable through the cable gland;
• connect the transmitter according to the figure below, paying attention to the correct tightening of the bolts fixing the conductor core to the terminal;
• check the correct fixing of the HART local communication jumper;
• tighten the rear cover of the transmitter body;
• leaving a small clearance of the cable inside the body, tighten the gland nut so that the gland seal is clamped on the power cable.

7.1.2. 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 communicator unit or modem connected to a  computeror a smartphone. In order to establish the local communication, it is necessary to:

•  remove HART communication jumper (item 2);
•  connect the communicator or modem to electrical terminals (item 7).

Opening of the HART jumper results in applying resistance of 240 Ω in series in line 4…20 mA. This resistance reduces voltage on transmitter supply terminals by approximately 5 V DC for Exd or Exi/Exd transmitters (5,28 V DC for standard or Exi transmitters) for maximum current that can be set by the transmitter. To avoid the supply voltage deficit on the transmitter terminals, the HART jumper must be dismantled only for the time of performing the HART local communication.
Connection diagram of the communicator or modem to transmitter power supply and measurement system is presented below:

  ** Minimum supply voltage with backlight on. Possibility of turning off the backlight only by manufacturer at the transmitter production stage (then Umin=10,5 V DC).

7.2.2. 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.
Ammeter connection diagram – see: ➔ Figure 5. Electrical connection to transmitter.
7.2.3. Specifications of electrical switching terminals
Internal electrical switching terminals are suitable for conductors with the cross-section from 0,5 to 2,5 mm² . The internal and external electrical ground terminal of the body is suitable for conductors with cross-section from 0,5 to 5 mm² .
7.2.4. Cabling specification
Aplisens S.A. recommends using two-wire screened twisted pair cable. The outer diameter of the cable shell from 5 to 9 mm is recommended.
7.2.5. 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 IS, Exd, XP, Exi/Exd or IS/XP transmitters under normal operation conditions is defined as I_max = 20,500 mA

• E, where E is the acceptable safety error, which is ± 0,160 mA. The maximum current of standard 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:

where:
U – voltage at the supply terminals of the 4…20 mA current loop [V].
Umin – minimum supply voltage of transmitter ➔ Table 3. Permissible transmitter supply voltages.
RL_MAX – maximum power supply line resistance [Ω].
7.2.6. Shielding, equipotential bonding
When using a cable in the screen, connect the screen on one side to ground, preferably in place where transmitter is powered.
7.3. Equipotential bonding
When using an intrinsically safe transmitter with an additional overvoltage protection, having the designation “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.
7.4. Overvoltage protection
Transmitters comply with EMC standards for safety-related products used in general industrial environment. Transmitters in standard and flameproof versions are fitted with overvoltage protection. 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 grounded. Overvoltage protection parameters in transmitters in standard, Exd, XP or SA versions:

• discharge threshold voltage: 230 V DC;
•  discharge threshold impulse voltage: 450 V (impulse 100 V/µs);
• discharge threshold impulse voltage: 600 V (impulse 1000 V/µs);
• discharge current for 1 surge: 20 kA, 8/20 µs;
• discharge current for 10 surges: 10 kA, 8/20 µs;
• discharge current for 300 surges: 200 A, 10/1000 µs.

7.5. 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?
•  Are the transmitter covers tightened?
•  Are the cable gland and the gland plug tightened?

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.
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 Exd or Exi/Exd (also IS, XP, IS/XP) version, diagnosed dangerous states or malfunctions of the internal transmitter systems result in setting the alarm current I_AL < 3,600 mA. For transmitters in standard or Exi version, 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 figures below shows the normal operation ranges of the transmitter process output and the ranges of saturation and alarm currents.

Figure 9. Set range current, saturation currents, alarm currents of transmitters in Exd or Exi/Exd (also IS, XP, IS/XP) 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 I_AL < 3,600 mA for internal diagnostic alarms.
6.  Alarm current area I_AL > 20,660 mA for alarms related to safe failures with external diagnostics.

Figure 10. 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 < 3,650 mA for internal diagnostic alarms.
6.  Alarm current area AL_H > 21,500 mA for internal diagnostic alarms.

The transmitter diagnostics continually tests the environmental parameters:

•  Temperature of the pressure measurement structure sensor.
•  Temperature of the ADC transducer converting the electric signal from the pressure sensor to the digital value of measurement.
• Temperature of the CPU structure (transmitter’s main microcontroller). For transmitters in Exd or Exi/Exd (also IS, XP, IS/XP) version, if the operating temperature limits are exceeded, the diagnostics will trigger an alarm I_AL < 3,600 mA. Temperature  return to permissible range of the transmitter operation will result in deactivation of the diagnostic alarm mode and return to normal operation. For transmitters in standard or Exi version, if alarms from 2, 3 and 4 process variable (temperatures) are enabled, when the transmitter operating temperature limits are exceeded, the diagnostics will trigger an alarm depending on the settings AL_L < 3,650 mA or AL_H > 21,500 mA. Temperature return to permissible range of the transmitter operation will result in deactivation of the diagnostic alarm mode and return  tonormal operation.

The transmitter diagnostics continually tests the pressure process parameters:

• If the pressure/differential pressure value increases above 50% of the base range width from URL point reaching the UPL point, the diagnostics of transmitter in Exd or Exi/Exd (also IS, XP, IS/XP) version will trigger an alarm I_AL < 3,600 mA. The return of the pressure / differential pressure below the UPL point will result in deactivating the alarm and returning the transmitter to its normal operation. In case of transmitters in standard or Exi version, if the pressure / differential pressure value increases to the upper limit of ADC measurement converting transducer, reaching the USAL point, the diagnostics will trigger an alarm depending on the configuration AL_L < 3,650 mA or AL_H > 21,500 mA. The return of the pressure / differential pressure below the USAL point will result in deactivating the alarm and returning the transmitter to its normal operation.
• If the pressure / differential pressure value decreases below 50% of the base range width from LRL point reaching the LPL point, the diagnostics of transmitter in Exd or Exi/Exd (also IS, XP, IS/XP) version will trigger an alarm I_AL < 3,600 mA. The return of the pressure / differential pressure above the LPL point will result in deactivating the alarm and returning the transmitter to its normal operation. In case of transmitters in standard or Exi version, if the pressure / differential pressure value decreases to the lower limit of ADC measurement converting transducer, reaching the LSAL point, the diagnostics will trigger an alarm depending on the configuration AL_L < 3,650 mA or AL_H > 21,500 mA. The return of the pressure / differential pressure above the LSAL point will result in deactivating the alarm and returning the transmitter to its normal operation.

The transmitter diagnostics continually tests electric parameters and software resources of transmitter:

•  If the inner diagnostics detects the malfunctioning or failure of the transmitter which are not critical with regard of integrity of hardware and software – software of the transmitter in Exd or Exi/Exd (also IS, XP, IS/XP) version will activate alarm I_AL < 3,600 mA. The diagnostic alarm condition will continue until the failure or damage is resolved. Error/failure number Exxxx will appear on LCD2; the ERROR message will be displayed on LCD3. The image will blink to attract the operator’s attention. The transmitter will set the current output to alarm status I_AL < 3,600 mA. In case of transmitter in standard or Exi version, software will activate alarm depending on the configuration AL_L < 3,650 mA or AL_H > 21,500 mA. The diagnostic alarm condition will continue until the failure or damage is resolved. Error/failure number Exxxx will appear on LCD2; the ERROR message will be displayed on LCD3. The image will blink to attract the operator’s attention.
• If the internal diagnostics detects malfunctioning or failure of the transmitter which are critical from the point of view of integrity of hardware and software, such as the hardware error of RAM, FLASH, SVS, CPU logs, mathematical computation error, or if there is a difference exceeding 1% between the set process current and the current measured in the line, the transmitter will immediately stop operation and activate the critical diagnostic alarm mode. The transmitter display will be switched off. HART communication with the transmitter will not be possible. In case of transmitter in Exd or Exi/Exd (also IS, XP, IS/XP) version, in the critical diagnostic alarm mode the additional protection of the transmitter disconnects its power supply from loop 4…20 mA. In such a case, alarm current I_AL is much lower than 3,600 mA and is less than 0,500 mA. The transmitter will remain in OFF state until the power is disconnected and the transmitter is switched on again. In case of transmitter in standard or Exi version, in the critical diagnostic alarm mode the additional protection of the transmitter will lower the current in the loop 4…20 mA. In such a case, alarm current I_AL is much lower than 3,650 mA, amounting about 0,150 mA. The transmitter will remain in the critical alarm status for approx. 10 seconds, then it will attempt to restart. When the internal diagnostics detects no hardware errors after restart, the transmitter will return to normal operation.

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;
•  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);
• LCD display configuration parameters;
• 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 communication;
• 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.

8.4. Correction of impact of spacing of distance separators on site

In pressure / differential pressure transmitters with distance separator(s), it is required to make an adjustment depending on the impact of the separator position. The adjustment is made after the transmitter has been installed on site, before filling the plant. To do this, select “SETLRV” and “BYPRES” in the transmitter menu. Upon acknowledgement (“DONE”), a 4 mA signal, including the impact of the separator positions, is set in the transmitter. The 20 mA signal is set by selecting “SETURV”. For level measurements, fill the tank to a level corresponding to 20 mA, select “BYPRES” and confirm. If it is not possible to fill the tank/plant to the value corresponding to the 20 mA signal, the URV value may be set by selecting “BYVALU” function and entering the value. The value (in pressure units) is calculated by adding the planned measurement span value to the pressure value (PV) obtained after setting the LRV signal (4 mA).

Once the transmitter parameters have been entered and it has been reset at the workstation, it is required to:

• Secure the device against the possibility of making changes in the local setpoint change MENU.

•  Set your own password different from default password of “00000000”. The new password may consist of any combination of 8 hexadecimal characters 0…9, A…F. Store the password in a safe place.
  If the password is lost, its restoration or resetting to factory settings may only be performed by the manufacturer.

• Activate the setpoint change lock to secure the transmitter against accidental, unintentional change of parameters.

Pressure reset can be done via local setpoint change MENU or HART communication. The remaining operations described in this section may only be performed using HART communication.
For Exd or Exi/Exd (also IS, XP, IS/XP) type transmitters, opening the housing cover in the hazardous zone in order to use the local setpoint change MENU is forbidden.

8.5. Flow measurements
Differential pressure transmitter APR-2000ALW can be used for venturi flow measurements. Flow measurements often require setting of pressure-processing characteristics for output current setpoints other than linear. In APR-2000ALW transmitter the following characteristics are available for the user:

•  linear characteristics;
• second-stage root characteristics with relay characteristics and 0,2% hysteresis in the deadband
• manufacturer’s dual linear characteristics No.1+ second-stage root characteristics for constant deadband = 0,6% of setpoints;
•  manufacturer’s single linear characteristics No.2+second-stage root characteristics and 0,2% hysteresis in the deadband;
•  square characteristics;
•  special characteristics based on user-modified table.

8.6. Level measurements
Transmitters APC-2000ALW, APR-2000ALW, APR-2000ALW with diaphragm seals can be used for liquid level measurement in open or closed tanks. Examples of transmitter installation are shown in ➔ Figure 4. Examples of transmitter installation on tanks. The transmitter can be configured in physical units of liquid column such as water and mercury at several temperatures of the liquid. It is also possible to enter the user’s unit and perform any scaling of the setpoint indication. In case of tanks with irregular shapes, it is possible to use the user’s characteristics to compensate the effect of the shape on the converted volume of liquid in the tank.
8.7. Pressure and differential pressure measurements
The APC-2000ALW transmitter is intended for measuring the relative (overpressure and underpressure) and absolute gas, vapour and liquid pressure. Examples of transmitter installation are shown in ➔.Figure 2. Examples of pressure transmitter installation. The transmitters APR-2000ALW and APR- 2000ALW with diaphragm seals measure differential pressure on orifices, impact pressure tubes, filters, level in pressure tanks, etc. Examples of transmitter installation are shown in ➔.Figure 3. Examples of differential pressure transmitter installation. The transmitter may be configured for one of many physical units of pressure. It is also possible to enter the user’s unit and perform any scaling of the setpoint indication. For more issues regarding pressure, vacuum, differential pressure, level, flow measurements, refer to the Technical Information.

9.1. Local LCD display
The LCD has three primary information fields identified in the figure below as LCD1, LCD2, LCD3.

Figure 12. Display information fields
LCD1 field:
[mA] – value (milliamperes) of process current in line 4…20 mA, proportional to the measured pressure.
[%] – value (percentage) of the setpoint U(t) of current controller in current loop 4…20 mA. This value is the ratio of the process current Ip(t) to the current range width according to the following formula:

LCD2 field:
The LCD2 field is used mainly to display floating point decimal values in a unit displayed on LCD3. In some cases, other messages may be displayed:
− ERROR in case of some operating errors or failure diagnosed in the transmitter, error/failure number Exxxx will appear on LCD2, the ERROR message will be displayed on LCD3. The image will blink to attract the operator’s attention. The transmitter in Exd or Exi/Exd (also IS, XP, IS/XP) version will set the current output to alarm status I_AL < 3,600 mA. The transmitter in standard or Exi version will set the current output to alarm status depending on the configuration I_AL < 3,650 mA or I_AL > 21,500 mA. In order to identify the cause, please refer to the chapter “Troubleshooting” placed in Technical Information;
− undEr if the limit below LRV of the set range (only in MID mode) is exceeded by the process, the LCD1 display of transmitter in Exd or Exi/Exd (also IS, XP, IS/XP) version will show the message undEr (under). The image will blink to attract the operator’s attention. The transmitter will set the current output to alarm status I_AL < 3,600 mA. For transmitters in standard or Exi version, the message will appear when 50% of the base range below the lower limit range of the set LRL (LSL) is exceeded. 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. The image will blink to attract the operator’s attention. The diagnostic alarm mode will be enabled depending on the settings I_AL < 3,650 mA or I_AL > 21,500 mA. Additionally, common status PV_OUT_OF_LIMITS and status PV_LOW_LIMITED in the Sensor Block will be set, which can be read out in the diagnostic tab via HART communication. If the limit below LRV of the set range (only in MID mode) is exceeded by the process, undEr (under) message will appear on LCD1. The image will blink to attract the operator’s attention. The transmitter will set the current output to alarm status depending on the configuration I_AL < 3,650 mA or I_AL > 21,500 mA;
− ouEr if the limit above URV of the set range (only in MID mode) is exceeded by the process, the LCD1 display of transmitter in Exd or Exi/Exd (also IS, XP, IS/XP) version will show the message ouEr (over). The image will blink to draw the operator’s attention. For transmitters in standard or Exi version, the message will appear when 50% of the base range above the upper limit range of the set URL (USL) is exceeded. After reaching the UPL and when above this value up to USAL, the transmitter freezes the refreshing of digital value of the measurement. In this situation, the message ‘’ovEr” will be displayed. The image will blink to attract the operator’s attention. The diagnostic alarm mode will be enabled depending on the settings I_AL < 3,650 mA or I_AL > 21,500 mA. Additionally, common status PV_OUT_OF_LIMITS and status PV_HIGH_LIMITED in the Sensor Block will be set, which can be read out via HART communication. If the limit above URV of the set range (only in MID mode) is exceeded by the
process, ouEr (over) message will appear on LCD1. The image will blink to draw the operator’s attention. The transmitter will set the current output to alarm status depending on the configuration I_AL < 3,650 mA or I_AL > 21,500 mA; − ● ● ● ● when the set position of comma (point) on LCD2 does not allow for the correct display of the process variable, four dots ● ● ● ● will appear on LCD. The image will blink to attract the operator’s attention. In this situation, change the decimal point position in the local setpoint change MENU or via HART communication.

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) or in active MID mode.
---|---

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 pressure reset 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 pressure reset 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 because 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 pressure reset in the absolute pressure measurement transmitter.

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 value and a new LRV value. 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.:

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 positions every 1 second. If the local MENU remains inactive for more than 2 minutes, after this time the transmitter will automatically leave the MENU mode and will display the process variable.

9.7. 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.
9.7.1. Compatible devices
The following devices may be used to communicate with the transmitter:
− Aplisens S.A. KAP-03, KAP-03Ex communicator (HART 5 only);
− 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.
9.7.2. 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.
9.7.3. Local HART communication jumper
The transmitter allows to use the local HART communication. To do this you can use a HART communicator unit or modem interoperating with a computer or a smartphone. In order to establish communication, it is necessary to:
− remove the HART communication jumper (➔Figure 6. Electrical connection 4…20 mA of HART to transmitter in standard version);
− connect the communicator or modem to terminals (➔ Connection of transmitter with the option of using local HART communication).

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 connections 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 incorrect 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 characteristics.
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.
10.4. 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 transmitter can be damaged.
10.5. Spare parts
Parts of the transmitter that may be worn or damaged and thus replaced: cover seal.
Other parts in the case of ATEX, PED type of transmitter may be replaced only by  the manufacturer or an authorized representative.
10.6. Repair
Faulty or non-operational transmitter shall be provided to the manufacturer.
10.7. 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.

SCRAPPING, DISPOSAL

Worn or damaged devices shall be scrapped in accordance with WEEE Directive (2012/19/EU) on waste electrical and electronic equipment or returned to the manufacturer.
