3.3. Principle of operation
Area of application The DT1315 xx xx Intrinsically Safe Output Isolator provide
signal transmission between the control equipment and
signal sources located in the safe area and actuators,
current to pressure converters, field process indicators,
operate in zone 0, zone 1 potentially explosive area.
The instruments isolate the input, the output and the power
supply.
The input signal may be 0-20 mA, 4-20 mA, 0-10 V, the
intrinsically safe output signal also may be
0-20 mA, 4-20 mA, 0-10 V.
Operating principle
The instruments are powered from a 19-29 VDC supply
trough a dual output high frequency DC-DC converter. One
output supplies power for the input (safe) side, the other
supplies power for the output (Ex) side. The DC isolation
and intrinsically-safe segregation are provided by high
isolation optocoupler. The DC signal transmission based on
a high precision pulse modulation-demodulation principle.
Power supply The instrument works from a 19-29 VDC supply voltage.
The power consumption is 1.6W.

3.4. Adjustment
The DT1315 xx xx doesn’t need any adjustment.
After connected to the power supply it is ready to work.
3.5. Indicators
The following figure shows the indicator on the instruments
front:
1. “power” green indicator indicates the power on state of
the instrument.
2. “error” yellow indicator indicates that the output is in
overload state. (Uout > 16 V, i.e. Rl > 800 ohm @ 20 mA)
3.6. Storage and transport
This instrument should be stored and transport in places
whose climatic conditions are in accordance with chapter
8.1 Technical specifications, as described under the title:
Environmental conditions.
The packaging of DT1315 xx xx consist of environment-
friendly, recyclable cardboard is used to protect the
instrument against the impacts of normal stresses occurring
during transportation. The corragulated cardboard box is
made from environment-friendly, recyclable paper. The
inner protective material is polyfoam and nylon, which
should be disposed of via specialized recycling companies.

4. Mounting
4.1. General instructions
The instrument should be installing in the safe area in a
cabinet with sufficient IP protection, where the operating
conditions are in accordance with chapter 8.1 Technical
specifications, as described under the title: Operating
conditions.
Mounting position
The instruments are designed in housing for mounting on
TS35 rail.
The instruments should be mounted in vertical position
(horizontal rail position).
There are spacers both sides of the housing to keep 5 mm
distance between the instruments for the sufficient cooling.
Horizontal mounting may cause overheating and damage of
the instrument.

4.3. Mounting procedure
The following figure shows the mounting procedures (fixing
on the rail):
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.
3. Check the hold of the fixing by moving the instrument
firmly.

5. Connecting
5.1. Preparing the connection
Select and prepare
connection cable
Always observe the following safety instructions:
• When you are going to install instruments in hazardous
area or install instruments which are connecting to
instruments are working in hazardous area you should take
note of the appropriate regulations, conformity and type
approval certificates of the DT1315 xx xx and other
instrument. 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.
Take note of the corresponding installation regulations for
Ex applications. In particular, make sure that no potential
equalization currents flow over the cable screen. Ground
only one side the cable screen (it’s recommended the
transmitter side). If necessary of grounding on both sides
(for suppress the influence of high frequency interference
signals) this can be achieved by use of a capacitor (e.g.
ceramic capacitor 1 nF, 1500 V) or separate potential
equalization. The low frequency potential equalization
currents are thus suppressed, but the protective effect
against high frequency interference signals remains.

6. Fault rectification
6.1. Fault finding
The fault finding must be carried out by trained and
authorized personnel only!
Use only an Ex proofed meter when measuring on the input
(EX) side.
•The green indicator is dark →check the power supply.
If the supply voltage is OK, the instrument is defective.
•There is no output signal →check the input signal.
If the input signal is OK, the instrument is defective.
When the result of fault finding is that the DT1315 xx xx is
defective call the manufacturer service department.
