which also conform to the applicable Canadian standards on
safety.
Observe the following points so that the device meets the
requirements of the UL approval:
- only indoor use
- maximum operating voltage: see technical data
- use only batteries with UL certification
2. Product identification
The device can be identified by its manufacturing label. It
provides the most important data. By the ordering code the
product can be clearly identified.
Fig. 1 Example of manufacturing label
NOTE
-
The manufacturing label must not be removed!
3. Mounting
3.1 Mounting and safety instructions
DANGER
Danger of death from airborne parts,
leaking fluid, electric shock
-
Always mount the device in a
depressurized condition!
WARNING
Danger of death from improper
installation
-
This device may only be installed by
qualified technical personnel who has
read and understood the operating
manual!
-
Do not use the display to tighten or
solve to the mechanical connection!
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
-
Never use the display as a mounting / dismounting
aid, otherwise the device or the plug-in connections will be
irreparably damaged. For mounting or dismounting the device,
only use the hexagon on the pressure port.
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
- The permissible tightening torque depends on the
conditions on site (material and geometry of the mounting point).
The specified tightening torques for the device must not be
exceeded!
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.
NOTES -
for mounting outdoors or in a moist
environment:
- Please note that your application does not show a dew point,
which causes condensation and can damage the device.
There are specially protected pressure measuring devices for
these operating conditions. Please contact us in such case.
- 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
DANGER
Danger of death from explosion
-
when used improperly
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 BAM
(DIN 19247)!
For oxygen applications > 25 bar, devices without seals are
recommended.

3.7 Positioning of the display module
The display module of the pressure gauge is rotatable so that
clear readability is guaranteed even on unusual installation
positions.
Fig. 2 Rotatability
4. Supply / changing the battery
The digital pressure gauge is supplied by a 3 V lithium-battery
(type CR 2450). Stored values / parameters are also kept after
changing the battery.
As soon as in the display the announcement of "battery" is shown,
a battery change is necessary This has only to be done in
switched-off condition.
The battery case is located in the removable display of the
digital pressure gauge DM 10 / DM 17.
To change the battery go ahead as follows:
1
Remove the cap and change the battery.
2
Make sure that the wires are not damaged when
changing the battery. Prevent twisting as well as tensile
stress.
3
Cap and the housing are sealed by an o-ring 55x1.5.
Check the sealing surfaces - these must be clean and
free of scratches. Make sure that the o-ring is seated in
the designated groove in the cap and is not squeezed.
4
Lock the device after that properly.
Fig. 3 battery case
NOTE -
An incorrect usage may cause a leak out of batteries
and so a damage the device!
NOTE -
Only use a battery of type CR 2450.
NOTE -
Make sure that the battery is connected correctly with
the corresponding contacts in the battery tray.
NOTE -
Never try to charge battery, demount or short-circuit it.
NOTE -
Use only batteries with UL certification.
NOTE -
Keep the battery away from heat and unshielded
flame.

Select / ON-button:
- switch-on of the device
- choosing of the pressure units
- calibration of starting point
- configuration of the switch-off automatic
Function / OFF-button
:
- switch-off of the device
- scrolling in the menu system
The indication of the measured value as well as the configuration
of the individual parameters occurs menu-driven via the LC
display. The individual functions can be set with the help of two
miniature push buttons located in the front.
The menu system is a closed system allowing you to scroll
forward through the individual set-up menus to navigate to the
desired setting item. All settings are permanently stored in an
Flash-EPROM and therefore available again even after a battery
change.

If you detect a shifting of the measured
value deviating from the offset, the display
can be re-calibrated via pushing the
Select/ON-button. The display shows
, the value has been recessed.
Differs the zero point from the ambient
pressure, it is a pressure reference
necessary.

5 minutes
The menu system will be leaved automatically after 10
seconds; the last sett value has been saved. If you scroll all
menu points you will leave the menu system after
SW OFF
.
After configuring the unit, the conversion of the pressure
range into the new unit will only occur after leaving the
menu system. Depending on the pressure range,
probably not all available units can be used.
