5.3. Measurements of operating temperature of transmitter
5.3.1.After installing the DPT-2000ALW transmitter for the medium maximum expected temperature and
expected the maximum ambient temperature measure out Tp temperature of the most hot place on the
surface of transmitter and determine the temperature transmitter class or a maximum surface
temperature according to p. 5.4.
When measuring the warmed media, above ambient, is recommended to determine the temperature of the
stub while is screwed into the transmitter or at the wall of the pipe or tank as shown below.
5.3.2. When medium is heated above ambient temperature it is allowed to determine the temperature class
of the transmitter or the maximum surface temperature Tp through the adoption of a maximum
temperature of the medium which provides the technological process. Measurement of Tp isn’t then
necessary.
If during the measurement of Tp for maximum temperature expected for the medium is not possible to
ensure the maximum expected ambient temperature after the measurement of Tp
one can estimate the potential growth in temperature Tp due to the increase of ambient temperature.
5.3.3. If the other elements of the plant have or may have a temperature higher than the highest temperature Tp
on the transmitter, security conditions must be ensured in accordance with accepted principles in such cases
5.4. Determination of the transmitter temperature class T * for gas and the maximum surface temperature
1. Determine the temperature class of the transmitter for the gas or the maximum temperature for
combustible dust depending on the temperature Tp from the formula:
T*Tp+0,1Tp+5K for class T3..T6
T*Tp+0,1Tp+10K for class T1, T2
2. Determine the maximum surface temperature transmitter for combustible dust from the formula:
T*Tp+0,1Tp
3. The following table contains the values of permissible ambient temperature depending on the
temperature Tp and temperature class of the transmitter.

5.5. With regard on kind of casing material (light alloy with large aluminium content), the user is obliged to
assure, that possibility of hitting casing does not step out in place of transmitter installation.
5.6. In transmitter casing are two holes to assembly of cable intakes from thread M20x1,5 or 1/2 NPT.
5.7. Normally transmitters are delivered without installed glands but with blank plugs (corks) in the second
hole. They are at table 1 and table 2 at list of packing glands and plugs agreeable with production
documentation and accepted by certificate station. Customer should install packing glands according to
tables 1 and plugs according to tables 2 (if plugs aren’t installed) or other accordance with flame-proof
standards.
5.8. It is necessary apply a shield cable or without shield cable with round cross-section in protection from
elastomer, not moisture absorbing, for example: YKSLY 2 * 1, YnTKSYekw 1 * 2 * 1, LIYCY 2 * In case
of need of use cable about different building customer should co-ordinate this with transmitters
manufacturer to choose intakes with cable diameter.
5.9. The general principles of connecting and the exploitation of transmitter in Exd realization should be
compatible with principles and relating standards for Exd casing devices how in p.2.1, in this including
also : EN600079-14, EN60079-17.
5.10. During service must be made a check of the tight fastening of covers and the packing glands and the
fastening of the cable in the glands. The casing and supply line must be inspected for mechanical
damage, and the transmitter rating plate for legibility. Periodic checks should also be made of the
diaphragm, which should not carry signs of damage. During maintenance it is recommended that the
threads of the covers be lubricated with non-acid vaseline.
Because of the transmitter damage possibility, the ambient temperature should not be allowed to
become higher than 80C, even when there is no explosion risk.

5. Permitted input parameters (based on data from the FTZÚ 14 ATEX
certificate, and certification documentation).
The transmitters should be powered via the associated power feeding and measurement devices
provided with the relevant intrinsic-safe certificates. The parameters of their outputs to the danger zone
should not exceed the limit power supply parameters for the below specified transmitters.
Temperature classes T4, T5, or T6 depend on the input power and maximum ambient temperature – see p.
5.1, 5.2, 5.3.The ambient temperature range is reduced to Ta = -20ºC to +60ºC if the devices is installed as
group I M1 equipment.
External connections are made via integral terminals and cable glands which must be of certified type if they
are mounted on the version f or combustible dust hazard application.

5.2. – for power supply with a “trapezial” characteristic
Ui = 24V Ii = 50mA Pi = 0,6W Ta 80°C and T5 and Pi = 0,45W Ta 40°C and T6
Example of power supply from a source with “trapezial” characteristic (see Fig. 2).
Fig. 2. Power supply from a source with “trapezial” characteristic
If Uo < then parameters Uq, Io, Po are interrelated as follows:
UQ = , Rw = , P0 = for U0 ≤ 1/2U
5.3. - for power supply with “rectangular” characteristic
Ui = 24V Ii = 25mA Pi = 0,6W Ta 80C and T5
The supply of power from a source with a “rectangular” characteristic means that the voltage of the Ex power
supply remains constant until current limitation activates.
The protection level of power supplies with a “rectangular” characteristic is normally “ib”.
The transmitter powered from such a supply is also a Ex device with protection level “ib”.
Example of practical provision of power supply.
– use a stabilized power supply with Uo=24V with protection level „ib” and current limited to Io=25mA.

6. CONSTRUCTION.
6.1. Measurement Principles.
A signal from measuring sensor, i.e. from thermometer resistor Pt100 or thermocouple, corresponding to
measured medium temperature, is delivered to the input of analogue-digital converter and converted to digital
form. In digital form it is sent, through an optoelectronic galvanic barrier, to the microcontroller. The
microcontroller reads measured values and, using built-in algorithms, calculates an exact value of temperature
on the basis of these algorithms. Calculated value is shown on integrated LCD display, which can be configured
depending on the needs (see p. 9.2.5). Digital value of measured temperature is converted to analogue signal
4...20[mA]. Built-in modem BELL202 and implemented communication stack HART Rev.5.1 allow for the
communication with the converter, using PC computer and appropriate software or communicator.
The transmitter’s output is fitted with a radio-noise filter and other elements protecting against ESD.
A block diagram of the transmitter is presented in Figure 1.
DPT ... converters monitors the operation of their measuring systems and the correctness of calculations and in
case when discrepancies occur they inform about an error displaying a message on LCD display and
generating an alarm current in the current loop (depending on configuration).
The measuring signal of sensor has a galvanic separation from measuring line.Thanks of that construction the
measurement susceptibility at interferences is reduced as well as the enlarged safety of work in the Ex and
flameproof applications.
6.2. Construction
The basic units of transmitter are: casing, shield with process connection, measuring sensor andelectronic
units, transforming signal from measuring sensor into unified output signal.
16 IOM-DPT-A: FEB 2014

6.2.1. Transmitter casing
A casing of DPT... transmitter is made of high-pressure casting of aluminium alloy or 316L steel. It consists of a
body, two bolted side covers (full and with pane), cable inlets and plug with M20x1,5 or ½ NPT thread.
Inside the casings is divided into two chambers, separated by a header. An additional header, with a ribbon
cable is intended for transmitting a signal from temperature sensor to the inside of a transmitter.
The casing is equipped with internal and external earth terminals.
6.2.2. Electronic board with display
The electronic board, along with a display, is installed in a housing made of polycarbonate, in the bigger of two
casing’s chambers, where it is possible to rotate it by 180every 90. A connecting board with terminal strip
(fig. 2a) and the elements of interference filter and protecting elements are installed in the second chamber.
6.2.3. Shields of the measuring insert
Within the framework of basic version there is a possibility to select one of five types of casings shown on fig.6.
The SW1 and SW2 shields are high-tension shields designed to welding.
The GB1, GN1 and G1 shields have threaded process connection and designed to screw in assembly sockets.
The T1 shield have flange process connection.
7. INSTALLATION OF TRANSMITTERS
The DPT–2000ALW transmitters can operate in any position.
During the installation of temperature transmitters the casing of electronic system should be protected against
exceeding of allowed temperatures. Suitable thermal covers should be used or the transmitters should be
mounted in such a position so the heat from medium does not heat up the casing.
When the transmitters are mounted, particularly in areas endangered by explosion, also the
heat conduction of sensor metal casing and ambient temperature for ensuring proper work
conditions and temperature classes should be taken into consideration.
Data specified in ”Annex Exi” are applicable for intrinsically safe versions.
Data specified in ”Annex Exd01” are applicable flameproof versions.
8. ELECTRICAL CONNECTION
8.1. General recommendations
8.1.1. It is recommended that twisted pair cabling be used for the signal lines. If the transmitter and signal line
are subject to a large amount of electromagnetic interference, then shield pair cable should be used. The signal
wires should not run alongside network power supply cables or near to large electrically-powered devices.
The devices used together with the transmitters should be resistant to electromagnetic interference from the
transmission line in accordance with compatibility requirements. It is also beneficial to use anti-interference
filters on the primary side of the transformers, the power supplies used for the transmitters and apparatus used
in conjunction with them.
8.1.2. Wet or rising damp inside transmitter can cause its damage.
When the isolation of the wires in the packing gland is ineffective (for example, when single
wires are used) the opening of the gland should be carefully sealed with an elastic sealing
compound to obtain IP66 protection. It is useful to form the segment of the signal wire leading
to the packing gland into a protective loop to prevent condensation from running down in the
direction of the gland..
8.2. Electrical connections
The DPT-... transmitters are to be connected as shown in fig. 2a – 2d.
In DPT-... transmitters, a 240Ω resistor is permanently fitted in series in the transmitter’s current circuit
and blocked up with jumper between <SIGNAL –> and <TEST –> as shown in fig.2a and 2b.
When the resistance in the current loop is lower than 240Ω it is necessary to jumper disassemble to
Hart communication.

8.3. Protection from excess voltage
8.3.1. The transmitters may be in danger from excess voltage caused by connection faults or atmospheric
electrical discharge.
Protection from excess voltage between the wires of the transmission line is provided by TVS diodes installed
in all types of transmitter (see the table, column 2).
8.3.2. In order to protect against excess voltage between the transmission line and the casing or earth (not
prevented by the diodes connected between the transmission wires), additional protection is provided in the
form of plasma surge arresters (see the table, column 3).
Also external protective devices may be used, e.g. the UZ-2 Delta Controls system, or others. When the
transmission lines are long, it is advantageous to use one protective device near the transmitter (or inside it), and
another near entry points to other devices used in conjunction with it.
Internal protection of transmitters:
8.3.3. The voltage in the protective elements must not exceed the maximum permitted values given in columns
2 and 3 of the table.
The insulation test voltages (500V AC or 750V DC) given in 5.1.1 refer to transmitters plasma surge
arresters - such protection is not used in Exi versions of transmitters.
8.4. Earthing
The transmitters are fitted with internal and external earth terminals.
9. SETTING AND REGULATION
9.1. Measurement ranges, Definitions
9.1.1. Nominal range
The maximum range of temperature, which the transmitter can measure is called the “nominal range” (for
specifications of nominal ranges see section 5.3).
The width of the nominal range is the difference between the upper and lower limits of the nominal range.
The internal characteristic conversion curve for the nominal range is coded in the transmitter’s memory.This is the reference curve used when making any adjustments which affect the transmitter’s output signal.
9.1.2. Set range
When the transmitter is in use the term “set (calibrated) range” is used. The set range is the range whose
lower end-point corresponds to an output current of 4mA and whose upper end-point corresponds to a current
of 20mA (or 20mA and 4mA respectively when the conversion curve is inverted).
The set range may cover the whole of the nominal range or only a part of it.
The width of the set range is the difference between its upper and lower end-points. T
he transmitter may be set to any range within the nominal range of temperature values, subject to the
restrictions set out in the table in section 5.3.
9.1.3. Factory range.
in case when lacks information about measuring range, transmitters are setting on " factory range".
/0 ... 100/ °C – factory range for transmitter with Pt100 sensor.
/0 ... 300/ °C – factory range for transmitter with "K"thermoelement.
18 IOM-DPT-A: FEB 2014
9.2. Configuration and Calibration
9.2.1.The transmitter has features which enable metrological and identification parameters to be set and
altered. The configurable metrological parameters affecting the transmitter’s output current include the
following:
a. lower end-point of the set range
b. upper end-point of the set range
c. unit
d. time constant
e. type of characteristic curve: linear or radical
f. decimal index
9.2.2. Other identification parameters, not affecting the output signal, include: device address, device type
code, factory identification code, factory device code, number of preambles (3÷20), UCS, TSD, program
version, electronics version, flags, serial number, label tag, description tag, date tag, message, record number,
sensing module number.
The process of setting the parameters listed in 9.2.1 and 9.2.2 is called “Configuration”.
9.2.3. Remote configuration of transmitters
Configuration and Calibration of the transmitter are carried out using an Delta Controls KAP communicator,
DPT2000 configuration software or using library EDDL software (software PC with Hart/RS232 converter).
A description of the functions of the KAP communicator is contained in the KAP Communicator Operating
Manual, and information on the Hart/RS232 converter can be found on the Hart/RS232/01 Converter
information sheet.
For purposes of remote calibration a system shown on the scheme on fig. 2a 2d should be prepared.
9.2.4. Local configuration of transmitters
If the option of local configuration is active, operator can change transmitter set using buttons being below
display. The access to buttons will get after unscrewing the side cover. Then we can also change the display
position turning it with 900 angle position. (see fig. 4).
If the option of local configuration is active, operator can change transmitter set using buttons being below
display. To enter at the local set change of the work mode, you should press one button and hold its about 4s.
If using buttons can't change the transmitter configuration , the local transmitter configuration is switched of
and to its switching on is necessary to use the KAP 3 Calibrator.
The buttons are signed with symbols: [↑] [↓] [◙]
After pressing by 4 seconds any of buttons there will appear on display “EXIT”.
If we will confirm this announcement across pressing and holding button [[◙] by 1 sec, we will go out from the
local change of the MENU set. If we will not confirm, we can move in MENU and change interesting us
parameters. The time of pressing [↑]] [↓] [◙] has to be longer than 1s.
Longer pressing and holding of [↑] [↓]buttons will cause an automatic scrolling through MENU structure, with step
of 0.33 s
Pressing button [↑] moves up in tree's structure MENU
Pressing button [↓] moves down in tree's structure MENU
Pressing [◙]confirms choice and leads change.
If no actions are taken in the area of MENU for a period longer than 2 min., then MENU mode will be quitted
and a process variable will be displayed.

9.2.5.1. Setting up a local LCD display
The LCD display configuration can do in dependence from needs. Changes of the display options in local
MENU are possible using buttons or remote way using communicator, or the PC software. If it is necessary the
display switching off is also possible. The display switching of function is possible with using communicator or
PC software only.
There 3 main displays are visible:
LCD1 – the current or guidance percent preset range display. In accordance with display configuration the
current value in 4 -20 mA current loop, or percent guidance preset range is possible to display.
LCD2 – the measured temperature digital value display; the calibrated temperature value according to
user’s units display; the process variable units or user’s units display; the MENUannouncement and other
information or warning announcement display. In the case the digital temperature value or the calibrated
temperature value display, the sign „–„ can be visible before displayed value. The decimal point position is
possible to set in local MENU or remotely. The temperature unit or user’s unit can be displayed.The
transmitter makes possible rescale on the user's individual the temperature value. To make this is
necessary with using communicator or PC software write the corresponding to beginning and to end
values of setting range as well as write the own unit name. After activating user's mode the rescale value
will be visible on display.
LCD3 – information display. During normal operation is designed for continuous display of the base unit or
the user units. In case of errors in the transmitter's work , it displays an error number. In manual mode, the
local change settings menu displays options of selecting the setting. It also displays errors related to the
implementation of commands in the local menu of the settings change.
Display backlighting - Local display is equipped in backlight, switching on and switching off with
jumper on electronic board. How to handle display backlight is shown in Figure 5. Figure 4 shows
how to change the display position by rotation.
After configuration it is important to protect the transducers using command HART [247].
During work transmitter should be safe prior to entries. This prevents accidental or intentional
changes configurational data. The protection function is accessible in KAP03 communicator, “
DPT2000 Configurator” software, as well as, in applying DD or DMT programs libraries.

9.3. Calibration.
The transmitter can be calibrated with reference values of the standard operating temperature sensor
transmitter to its scale (calibration input) or to current output 4 ... 20 (20 ... 4) mA - (current calibration).
The values set calibration points need not be equal to the upper and lower limit of the basic range. But they can
not exceed out up and down. The width of the calibration range shall not be less than the minimum width of the
setting range. In order to achieve the best accuracy it is recommended that the calibration points were close to
the beginning and end of the setting range. Calibration can be made using the KAP-03 or KAP-03Ex
communicator according to the procedure described in the "User's Guide" IO.KAP-03 p 11.3. or other tools
provided in clause 9.2.3.
10. INSPECTIONS AND SPARE PARTS
10.1. Periodic inspections
Periodic inspections should be made in accordance with the regulations to which the user is subject.
During inspection, the shield of the measuring insert should be checked for loose connections and leaks, the
electrical connectors should be checked with regard to tightness and the state of the gaskets, packing glands.
Check the characteristic conversion curve by following the procedures for “Calibration” and, where appropriate,
“Configuration”.
10.2. Unscheduled inspections
If the transmitters are installed in a location where they may be exposed to mechanical damage,
hydraulic impulses or excess voltage, or transmitter operate abnormal – inspections should be carried
out as required, check the characteristic of processing.
Where it is found that the signal in the transmission line is absent or its value is incorrect, a check
should be made on the line and its terminal connections.
Check whether the values of the supply voltage and load resistance are correct.
If a communicator is connected to the power supply line of the transmitter, a fault in the line may be
indicated by the message “No response” or “Check connection”.
If the line is in order, check the operation of the transmitter.
10.3. Spare parts.
Parts of the transmitter which may be subject to wear or damage and require replacement: cover and packing
gland gaskets .
Other listed parts, due to the specific features and requirements of explosion-protected
devices, may be replaced only by the manufacturer or by a firm authorized by the manufacturer.
11. PACKING, STORAGE AND TRANSPORT.
The transmitters should be packed singly or in sets, in such a way as to protect them from damage during
transportation.
The transmitters should be stored in multiple packs under cover, in a place free of vapours and reactive
substances, with an air temperature between +5°C and +40°C, and relative humidity of not more than 85%.
During transportation, the transmitters should be packed and secured so as to prevent them from shifting.
Any means of transport may be used, provided direct atmospheric effects are eliminated.
12. GUARANTEE

Fig.1. DPT... transmitters – block diagram.
For successful communication with transmitter the resistance in measuring loop, behind connected
device to communication, should be higher than 250Ω. If necessary install the additional resistor in the
line. The communicator or modem connecting ways to the measuring loop are presented at diagrams.
During increasing of resistance in the measure loop at making the good transmission, is necessary to
make sure that the tension falls at sum resistances in the loop don't lower minimum tension at
transmitter terminals. (see p.5.1.).

resistance in current loop is higher than 250Ω).

case of the resistance in current loop is smaller than 250Ω.
If Ro in current loop is lower than 250Ω is necessary to connect 240Ω resistor to current loop by
remove jumper from <SIGNAL-> and <TEST-> terminals.
After communication jumper should cam back at its place.
