2. For your safety

2.1. Authorized personnel

All operations described in this operating instructions manual must be

carried out only by trained and authorized specialist personnel. For

safety and warranty reasons, any internal work on the instruments

must be carried out only by DATCON personnel.

2.2. Appropriate use

The DT4220 E 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 on

the control panel.

Detailed information on the application range of the instrument is

available in chapter "Product description".

2.3. Warning about misuse

Nem megfelelővagy helytelen használat — alkalmazástól függően —

zavart okozhat a készülékhez kapcsolódó egyéb készülékekben,

rendszerekben.

2.4. General safety instructions

The DT4220 E Process Indicator is a high-tech instrument requiring

the strict observance of standard regulations and guidelines. The user

must take note of the safety instructions in this operating instructions

manual, the country-specific installation standard as well as all

prevailing safety regulations and accident prevention rules.

2.5. CE conformity

A DT4220 E is in conformity with the provisions of the following

standards:

EN 61326-1:2012 (EMC)

2.6. Environmental instructions

Protection of the environment is one of our most important duties.

3.3. Operating principle

Area of application The DT4220 xx xx xx (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 digit, 14.2 mm height LED display make process value easily

visible at a distance.

Options:

RL2

Two normally open relay contacts (SPST) for limit switching or for

simple control tasks.

IA / IP

4-20 mA / 0-20 mA galvanic isolated scaleable analogue output. The

output can be active (A) or passive (P).

Galvanic isolated power supply output for 2, 3 or 4 wires transmitter.

RS2

RS232 galvanic isolated communication output with MODBUS RTU

slave protocol. Only one instrument can be connected to the one

RS232 connector of PLC or to the computer.

RS4

RS485 galvanic isolated communication output with MODBUS RTU

slave protocol. 32 instruments can be connected to one RS485

connector of the PLC or to the computer.

Note: only one in five (IA, IP, TS, RS2, RS4) option can be

implemented at the same time. The option RL2 always can be

implemented independently another option.

DT4220 E

820180619-V0

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, drives the limit relays, the analogue output

and the communication output.

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, signal filtering,

display scaling, decimal point position, display refresh rate, limit

modes, limit values, 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:

DT4220 E xx xx xx: 19-50 VDC / 19-35 VAC 3 W / 3.5 VA

DT4220 E xx xx xx PS: 90-250 V AC/DC 3.5 VA / 3 W

DT4220 E

20180619-V0 9

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, indicators

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. "Rel1" yellow indicator for indicating that limit output 1 is in "on-

state" (LIMIT1).

3. "Rel2" yellow indicator for indicating that limit output 2 is in "on-

state" (LIMIT2).

4. "Status" yellow indicator for indicating that a successful data

exchange has granted through the communication output.

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.
