3.3. Principle of operation
Area of application
Principle of operation
The DT1310 xx xx Intrinsically Safe Temperature /
Resistance Transmitter provide signal transmission and
conversion between Pt100 / Pt500 / Pt1000 sensor or
resistance / potentiometer and signal processing unit.
The transmitter feature complete 3-way isolation: the input
to output and both to the power supply circuits are isolated.
The output signal may be:
0-20 mA, 4-20 mA, 0-10 V, 2-10 V.
The Pt100 / Pt500 / Pt1000 / resistance / potentiometer can
be connected to the input either with 2 / 3 or 4 wire.
The module features complete configuration of sensor input
variables and process signal outputs.
Some of the configuration options are: sensor type,
resistance range, signal output scaling, 2 / 3 or 4 wire
measuring mode, signal filtering, calibrated sensor curve
fitting, etc. The configuration software is capable of storing
all the parameters for future re-configurations.
The configuration parameters are downloaded from
the PC to the DT1310 xx xx via DT10 infrared
communicator interface. This interface connects to PC via
normal USB 2.0 type “A” connector.
The measuring current flows through the sensor /
resistance / potentiometer connected to the input. The
voltage drop on the measuring sensor is compared with the
voltage drop on the internal reference resistor. The voltage
difference is led to a 21 bit A/D converter. The digital output
signal of the
A/D converter is processed by a microcontroller.
The microcontroller produces a pulse width modulated
output signal which is proportional to the processed, scaled
measuring value. The output pulse is galvanic isolated by
an opto coupler. After filtering the pulse is converted into
analogue current or voltage signal.
Using the wireless infrared USB interface to configuration:
connect this to the PC USB port and pushing the “conf
start” button thru the hole on front of instruments. Provide
the optical visibility between interface and instruments
sensors. Instrument’s communication circuitry come into
active state and it is ready for communication with the
configuration software.

Power supply The instrument works from a 19-35 VDC supply voltage.
The power consumption is 1.4 W.
3.4. Adjustment
After connecting the DT1310 xx xx is ready to work with the
factory default parameters are written in Chapter 6.1. For
working with the default parameters there is no need any
adjustment. The detailed description of the setup can be
found in Chapter 7.

4. Mounting
4.1. General instructions
The instrument should be installed in a cabinet with
sufficient IP protection, where the operating conditions are
in accordance with chapter 10.1. Technical specification,
as described under the title: Operating conditions.
Mounting position
The instruments are designed in a housing for mounting on
TS-35 rail.
The instruments should be mounted in vertical position
(horizontal rail position).
Horizontal mounting may cause overheating and damage
of the instrument.

Mounting on the rail
The mounting doesn’t need any tool.
1. Tilt the instrument according to the figure; put the
instrument’s mounting hole onto the upper edge of the rail
(figure step 1.).
2. Push the instrument’s bottom onto the bottom edge of
the rail (figure step 2.), you will hear the fixing assembly
closing.

5. Connecting
5.1. Preparing the connection
Select and prepare
connection cable
Always observe the following safety instructions:
• The connection must be carried out by trained and
authorized personnel only!
• Connect only in the complete absence of supply voltage
• Use only a screwdriver with appropriate head
Take note the suitability of the connecting cable
(wire cross-section, insulation, etc.).
The wire cross-section should be 0.25-1.5 mm2.
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
For the input connection we recommended to use screened
cable. It’s an important rule that the power cables and
signal cables should lead on a separate way.

6. The first start-up, indicators
6.1. The first start-up
After connecting the DT1310 xx xx is ready to work with the
factory default parameters.
When you are going to use other parameters you should
set-up the instrument according to Chapter 7.
Factory default settings:
•Pt connecting 4 wire.
•Measuring mode: temperature measurement wit Pt100
sensor.
•Current output: 4-20 mA.
•Current output error value: 3.2 mA.
•Averaging: 16 measurement.
•Output refresh time: 0.5 sec.
•Sensor characteristics fitting mode: off.
•Output scaling: -200.0 °C ÷ 4 mA-t; +800.0 °C ÷ 20 mA.
•Password:”1000”.
•Wire resistance in 2 wire connecting: 0 Ohm.
•Potentiometer measurement mode and scaling:
0% = 0.00, 100% = 100.00. (for potentiometer
measurement first you should calibrate the potentiometer
according: Chapter 7.)

DT1310 xx xx

6.2. Indicators
(1) power (green): mode an communication indicator
(2) st. (red): mode and error indicator
The two indicator gives information in conjunction as
follows:
•Measurement mode:
power: light, st.: dark.
•Error state:
power: light, st.: blinking.
The number of blinkings gives the error information while
the output current is forced into 3.2 mA or 20.8 mA
(depends on setting).
1 blink: fatal error. (repairing: in factory service only).
2 blinks: input break (repairing: check the sensor and
wiring).
3 blinks: potentiometer mode is selected but the
potentiometer is not calibrated (see Chapter 7.)
4 blinks: measuring value out of range.
5 blinks: analog output scaling error (the instrument is
unable to convert the measured value into the 3.9-20.1 mA
range, while the output current is forced to 3.2 mA or
20.8 mA, depends on setting). (see Chapter 7.)
•Configuration mode:
After connecting the infrared interface to the PC USB port
and pushing the “conf start” button and placing opposite the
interface optics and the instruments optics, starting the
configuration program and opening the proper virtual serial
port, the instrument is ready to communicate with the
program (for selecting the proper virtual port begin with the
last and than try the others).
st.: light, power: short flash in a case when a successful
communication has granted.

configuration software on the CD
•PC
Installing the USB driver Before you use the configuration software first time, you
must to install the USB driver. This driver provides the
virtual COM port for configuration software.
Run the \DT1310 (DT10)\USB Driver\USB driver
installer.exe program on CD.

PC USB port.
2. Put the instruments under supply voltage.
3. Start the DT1310.exe configuration program.
4. Select the appropriate serial port.
5. Click on the „Open Serial Port” button.
6. Push the "conf start" button and place opposite the
interface optics and the instruments optics.
7. st. (red) indicator gives light, signing that the instrument
is configuration mode.
8. power (green) indicator signs with a short flash the
successful communication between the program and the
instrument.
9. Use the configuration software as is written on the
following pages.

7.2. Connecting wire setting
Function The Pt / resistance / potentiometer can be connected to the
input either with 4 / 3 / 2 wire.
The 4 wire connection gives the best result: the instrument
is able to compensate the connecting cable resistances.
The 3 wire mode is a compromise it may give a good result
when all the 3 wire have same resistance.
The two wire mode is the cheapest mode, use only when
there is no other possibility.
[Factory default: 4 wire.]
1. Select the appropriate connecting wire mode by clicking
the button.
The figure shows the factory default setting.
Sequence of operations
Warning! Select always appropriate wiring mode.
Inappropriate selection may cause measuring error.
