3.3. Operating principle
Area of application The DT4227 UI (PS) Process Indicator enable process variable
0-20 mA, 4-20 mA, 0-10 V, 0-5 V, 2-10 V to be displayed in
engineering units ont he control panel.
Any optional display range can be assigned to the input signal range.
Large 5 digits LED display make process value easily visible at a
distance.
Operating principle The input current or voltage to be measured is led to the 23 bit A/D
converter through a protection and signal condition circuit.
The digital output signal of the A/D converter is processed by a
microcontroller.
The microcontroller drives the 5 digit LED display, processes the front
panel membrane keypad.
Easy on-site configuration through the front panel membrane keypad
is a major advantage of the microcontroller-based technology. The
configuration parameters: input signal selection, display scaling,
decimal point position, display refresh rate, etc. are stored in FRAM.
The settings are protected by a two-level password against
unauthorized manipulation.
Power supply The instrument has two power supply version:
DT4227 UI 24 VDC power supply
DT4227 UI PS 230 V AC/DC power supply

DT4227 UI (PS)

3.4. Adjustment
The instrument can be adjusted through the
3 button front panel keypad. All configuration parameters are stored in
the instrument FRAM for unlimited time, even when the supply voltage
being switched off.
The instrument doesn't need any internal adjustment.
3.5. Display
The following figure shows the front panel of the instrument:
1. 5 digit 7 segment LED for displaying the measured value and the
mnemonic messages.
2. The "Status" indicator not used in this device.
3.6. Storage and transport
This instrument should be stored and transport in places whose
climatic conditions are in accordance with Chapter 10.1. Technical
specifications, as described under the title: Environmental
conditions.
The packaging of instrument consist of environment-friendly,
recyclable cardboard is used to protect the instrument against the
impacts of normal stresses occurring during transportation. The
corrugated cardboard box is made from environment-friendly,
recyclable paper. The inner protective material is nylon, which should
be disposed of via specialized recycling companies.

5. Connecting
5.1. Preparing the connection
Always observe the following safety instructions:
•Connect or disconnect only in the complete absence of line voltage
•Take note the data concerning on the
overcurrent protection in installation.
•Use only a screwdriver with appropriate head
Select connecting
cable
Take note the suitability of the connecting cable
(wire cross-section, insulation, etc.).
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
In case of mains connection the wire cross-section should be 1.0 mm2
(min.).
It's an important rule that the power cables and signal cables should
lead on a separate way.
Preparing cables
Prepare the cable for the connection.
Strip approx. 6 mm insulation.
In case of using flexible cable, use crimped wire end.

6. Display and manual controls
6.1. The first start-up
The factory default setting is:
Selected input signal: 4-20 mA
Scaling: 4 mA ÷ 0%
20 mA ÷ 100%
When the input current is 0 mA, you can see . on the display.
When the input current is 12 mA, you can see . on the display.
In the case of an error
message
If anything else appears on the display instead of the scaled input
signal (e.g. a message with blinking letters), then it is an error
message of the instrument.
The most frequented error messages are the following:
1. There is only a flashing  at the left side of display:
The input signal is more than the specified input range. The
instrument can not measure it.
Solution: check the input signal with a digital multimeter.
2. There is only a flashing  at the left side of display:
The input signal is less than the specified input range. The instrument
can not measure it.
Solution: check the input signal with a digital multimeter.
3. There is a flashing  or  on the display:
The input signal is less or more than the displayable value. The
instrument can not display it.
Solution: modify the low value of scale or the high value of scale,
change the decimal point position if necessary.
In order to define the error more accurately, please go to Chapter 6.2.
