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.

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.

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.
