The device complies with the applicable standards and regulations listed in EU and UK Declaration of Conformity. The CE or UKCA nameplate marking is dependent on delivery region of the transmitter.

INSTALLATION

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 gas-eous medium, this may mean installing the transmitters above the pressure measuring point, and for liquids below this point.

Examples of transmitter installation

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 the 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.

Closing of housing covers, sealing

The front and rear cover threads have a factory coating, therefore no additional coating is required. Before tightening the covers, make sure that the thread surfaces are free of contamination, e.g. sand. It should be possible to screw the covers smoothly. If resistance is felt when tightening, on the thread there is probably dirt which must be removed before tightening.

• The transmitter housing does not provide tightness if the housing or covers thread is damaged.

Some transmitter applications require an interlock and sealing of covers to prevent unauthorized access to settings and adjustments. The method of sealing transmitters is shown in the following figure:

ELECTRICAL CONNECTION

Cable connection to transmitter internal terminals

• All connection and installation operations must 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.

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.

In hazardous zone, do not unscrew the housing covers after connecting the Exd (XP) flameproof transmitter to the power source.

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 computer or 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 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.

Table 3. Permissible transmitter supply voltages

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 6. Electrical connection to transmitter.

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.

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.

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 cur-rent 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 resistance value in the power circuit (along with the power cables resistance) is defined by the formula:
• where:
• RL_MAX – maximum power supply line resistance [Ω],
• U – voltage at the supply terminals of 4…20 mA current loop [V],
• Umin – minimum supply voltage of transmitter [V] (➔ Table 3. Permissible transmitter supply voltages).  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.

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.

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 Exi SA (IS SA) versions:
  • discharge threshold voltage: 230 V DC;
  • discharge threshold impulse voltage: 450 V (pulse 100 V/µs);
  • discharge threshold impulse voltage: 600 V (pulse 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.

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).
• Use the transmitter within the allowable pressure limits. Risk of injury due to component breakage after exceeding the maximum permitted operating pressure.

Alarm configuration

• Transmitters has a developed internal diagnostics resulting from the requirements of PN-EN 61508 standard. The transmitter’s internal diagnostics monitors the operation of its electronic circuits, process and environmental parameters, ensuring the required level of functional safety. Diagnosis of dangerous statuses or malfunctioning of the internal transmitter systems results in setting alarm current I_AL < 3,600 mA.
• The user cannot disable diagnostics or change the value of alarm current. The figure below shows the normal operation ranges of the transmitter process output and the ranges of saturation and alarm currents.

Figure 10. 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 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.

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).
• If the transmitter 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.

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 will trigger an alarm I_AL < 3,600 mA;
• if the pressure / differential pressure value decreases below 50% of the base range width from LRL point reaching the LPL point, the diagnostics will trigger an alarm I_AL < 3,600 mA.
• The return of the pressure / differential pressure into area between point LPL and point UPL 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 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 dis-played on LCD3. The image will blink to attract the operator’s attention;
• If the inner 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 dis-play will be switched off. HART communication with the transmitter will not be possible. 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.

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,
  • transmitter tag (TAG),
  • LCD display configuration parameters,
  • setting of the settings change lock password.

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 resetting 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.

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 sepa-rator 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 pass-word 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 (XP) type transmitters, opening the housing cover in the hazardous zone in order to use the local setpoint change MENU is forbidden.

Flow measurements

• Differential pressure transmitter APR-2000ALW Safety can be used for venture flow measurement. Flow measurements often require setting of pressure processing characteristics for output current setpoints other than linear. In APR-2000ALW Safety the following characteristics are available for the user:
  • linear characteristics;
  • second-stage root characteristics with relay characteristics and 0,2% hysteresis in the dead-band;
  • 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.

Level measurements

• Transmitters APC(R)-2000ALW Safety 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.

Pressure and differential pressure measurements

• [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 will set the current output to alarm status I_AL < 3,600 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, undEr (under) message will appear on LCD2. 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;
  • ouEr if the limit above URV of the set range (only in MID mode) is exceeded by the process, ouEr (over) message will appear on LCD2. The image will blink to draw the operator’s attention. The transmitter will set the current output to alarm status I_AL < 3,600 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.

Abbreviations of physical units of pressures and levels and their description:

Abbreviations of temperature measurement point name:

• SENS °C
  • temperature of pressure / differential pressure sensor measurement structure in degrees
• CPU °C
  • temperature of the main CPU structure in degrees Celsius.

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[\]^_`

Local buttons

• Local buttons are used to enable the configuration mode of some transmitter parameters and to navigate 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.

Local configuration of setpoints

• Transmitter enables local configuration of some of the most common setpoints via local buttons and local LCD display.

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 in MENU.

Acceptance of local setpoints

• The button 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.

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.
