there from.
Fig. 1 Manufacturing labels
NOTE
-
The manufacturing labels must not be removed!
3. Mounting
3.1 Mounting and safety instructions
WARNING
-
Mount the device (pressure transmitter
module) always in the state without
pressure and apart from the display!
WARNING
-
This device may only be installed by
qualified technical personnel who has
read and understood the operating
manual!
WARNING
-
Do not use the display to tighten or
solve to the mechanical connection of
the pressure transmitter module!
NOTE
-
Handle this electronic precision measuring device
carefully in packed as well as in unpacked condition!
NOTE
-
Handle the unprotected diaphragm very carefully - it is
very sensitive and may be easily damaged.
NOTE
-
The device may not be thrown!
NOTE
-
To avoid damaging the diaphragm, remove packaging
and protective cap only directly before starting up the device. A
delivered protective cap must be stored!
NOTE
-
Place the protective cap on the pressure port again
immediately after disassembling.
NOTE
-
Do not use any force when installing the device to
prevent damage of the device and the plant!
NOTE
-
Take note that no inadmissibly high mechanical
stresses occur at the pressure port as a result of the installation,
since this may cause a shifting of the characteristic curve or to the
demage.
NOTE
-
In hydraulic systems, position the device in such a way
that the pressure port points upward (venting).
NOTE
-
Provide a cooling line when using the device in steam
lines.
NOTE
-
If the device is installed with the pressure port pointing
upwards, ensure that no liquid drains off on the device. This
could result in humidity and dirt blocking the gauge reference in
the housing, and could lead to malfunctions. If necessary, dust
and dirt must be removed from the edge of the screwed joint of
the electrical connection
NOTE
-
The specified tightening torques must not be
exceeded!
NOTES -
for mounting outdoors or in a moist
environment:
- Make sure the ambient temperature will not fall below the dew
point. These conditions may caused the water condensation
inside the display unit and damage the electronics
components. If condensate occurs inside the unit, remove the
battery cover and allow the device to dry at normal min
temperature 24 hours.
- Connect the device electrically straightaway after mounting or
prevent moisture penetration, e.g. by a suitable protective
cap. (The protection rating specified on the data sheet applies
to the connected device.)
- Select the mounting position such that splashed and
condensed water can drain off. Stationary liquid on sealing
surfaces must be excluded!
- Mount the device such that it is protected from direct solar
radiation. In the most unfavourable case, direct solar radiation
leads to the exceeding of the permissible operating
temperature. This must be excluded if the device is used in
any explosion-hazardous area!
- A device with gauge reference in the housing (small hole next
to the electrical connection) must be mounted such that the
gauge reference is protected against dirt and humidity. If the
transducer is exposed to liquid admission, the gauge
reference will be blocked, and the equalization of air pressure
will be prevented. In this condition, a precise measurement is
impossible and damage to the transducer may occur.
3.2 Conditions for oxygen applications
Make sure that your device was ordered for oxygen applications
and delivered accordingly. (see manufacturing label – ordering
code ends with the numbers “007”)
Unpack the device directly prior to the installation.
Skin contact during unpacking and installation must be avoided
to prevent fatty residues remaining on the device. Wear safety
gloves!
The entire system must meet the requirements of the German
Federal Agency for Material Testing [BAM] (DIN19247)!
For oxygen applications > 25 bar, transducer types without seals
are recommended.
Transmitters with o-rings of FKM Vi 567: permissible maximum
values: 25 bar / 150° C (BAM approval)
3.3 Mounting steps for connections according
to DIN 3852
NOTE
- Do not use any additional sealing material such as
yarn, hemp or Teflon tape!
The O-ring is undamaged and seated in the designated
groove.
The sealing face of the mating component has a flawless
surface. (R

Screw the device into the mating thread by hand
2
Then tighten it using an open-end wrench:
1/4" NPT: approx. 30 Nm; 1/2" NPT: approx. 70 Nm
3.6 Installation steps for internal threads M20x1.5 and
9/16" UNF (for DM01-500 HD)
WARNING
Danger of injury
-
Due to wrong installation
-
Do not use any seal!
NOTE
- The high-pressure tube will seal metal-to-metal in the
chamfer of the pressure port. (sealing cone 60°)
1
Screw the high-pressure fitting into the internal thread of
the pressure transmitter.
2
Then tighten it using an open-end wrench. The required
tightening torque depends on the manufacturer's
specifications for the high-pressure pipe you are using.
(permissible tightening torque for pressure transmitter:
max 120 Nm)

7.1 Operating- and display elements (display)
Fig.4 Display and operating foil
The display of the measuring value as well as configuring the
single parameters occurs menu-steered about a LC display
capable of graphic arts. The single functions are regulated on the
basis of three-front-sided arranged push buttons.
The menu system is closed, thereby one can "browse" forward as
well as backward by the single setting menus to reach to the
desired setting point.
