2. For our safet

2.1. Authorised personnel

A operations described in this operating instructions

manua must be carried out on y by trained and authorised

specia ist personne . For safety and warranty reasons, any

interna work on the instruments must be carried out on y by

DATCON personne .

2.2. Appropriate use

The DT9000 N is a 4-20 mA oop-powered process

indicator. Detai ed information on the app ication range of

the DT9000 N is avai ab e in chapter „Product description”.

2.3. Warning about misuse

Inappropriate or incorrect use of the instrument can give

rise to app ication-specific hazards, or demage to system

components through incorrect mounting or adjustment.

2.4. General safet instructions

The DT9000 N is a high-tech instrument requiring the strict

observance of standard regu ations and guide ines. The

user must take note of the safety instructions in this

operating instructions manua , the country-specific

insta ation standard as we as a prevai ing safety

regu ations and accident prevention ru es.

3.2. Principle of operation

Area of application DT9000 N is an process indicator enab e inear process

variab es to be disp ayed.Two iso ated outputs are avai ab e

with different operating modes for imit signa ing or for

simp e contro purposes.

DT9000 N is housed in a mou ded po ycarbonate case

hauseproof to IP65 for insta ation in the fie d or on the

contro pane .

Operating principle The 4-20 mA current f ows through a measuring resistor

and is converted by a 16 bit A/D converter into digita va ue.

The digita va ue is processed by a microcontro er. The

user may set up the the configuration parameters: sca ing,

decima point position, disp ay refresh rate, signa fi tering,

imit modes, imit va ues, etc. through the front pane

membrane keypad and the parameters stored in EEPROM.

A two eve password protects the settings from

unauthorised changes.

Large 4 ½-digit, 20.5 mm height iquid crysta disp ay make

process variab es easi y visib e at a distance. A abe

defining the appropriate engineering unit may be attached

to the right of the disp ay.

DT9000 N has two optica y iso ated transistor outputs for

imit signa ing or for simp e contro purposes.

Power suppl DT9000 N is oop-powered from 4-20 mA signa , dropping

ess than 2 V at 20 mA.

DT9000 N

3.3. Adjustment

DT9000 N can be adjusted through the 3 button front pane

keypad. A configuration parameters are stored in the

instrument EEPROM for un imited period of time, even

when the oop current beeng switched off.

In factory setting the DT9000 N disp ays the 4-20 mA oop

current with a reso ution of three decima s.

The instrument doesn’t need any interna adjustment.

3.4. Storage and transport

This instrument shou d be stored and transport in p aces

whose c imatic conditions are in accordance with Chapter

10.1. Technical specifications, as described under the

tit e: Environmenta conditions.

The packaging of DT9000 N consist of enviroment-friend y,

recyc ab e cardboard is used to protect the instrument

against the impacts of norma stresses occurring during

transportation. The corrugated cardboard box is made from

environment-friend y, recyc ab e paper. The inner protective

materia is po yfoam and ny on, which shou d be disposed of

via specia ised recyc ing companies.

4. Mounting

4.1. General instructions

Use the enc osed sea when mounting DT9000 N on pane

to assure IP 65 protection between the instrument and the

pane from the front side (on y pane mounting version).

Mounting positions Se ect a mounting position you can easi y read the disp ay

reach for mounting and connecting the instrument and that

minimises the hazard of water, dust or dump getting into the

instrument.

Mounting cable entries The insrument is equipped with one PG11 cab e entry and

two additiona ho e equipped with sea ing p ugs. Two PG11

cab e entry is accessory. If required more than one cab e

entry (see chapter 5.) put out the sea ing p ug turning it in

antic ockwise direction. To put in the cab e entry use the

sea ing turn it in c ockwise direction. Tighten the screws so

much that ensures the desired sea ing. Use on y appropriet

too s.

4.3. Mounting as a wall-instrument

Removing the front

cover

In order to remove the front cover, first remove the four

fixing screws as shown in the drawing. A screwdriver of

appropriate head-size on y shou d be used. Using

screwdrivers with inappropriate head-size may cause a

damage in the screws’ heads or in the instrument front

pane .

Remove the screws by turning them in antic ockwise

direction as shown in the drawing Step (1). The screws are

secured against fa ing out. After this you can simp y take

away the front cover from the housing (2) and you can open

it by turning it downwards (3). P astic ties are used to fasten

the front cover to the housing, preventing it from fa ing.
