Fig. 1 Manufacturing labels
NOTE
-
The manufacturing labels must not be removed!
3. Mounting
3.1 Mounting and safety instructions
DANGER
Danger of death from explosion,
airborne parts, leaking fluid, electric
shock
-
Always mount the device (pressure
transmitter module) in a depressurized
condition and apart from the display!
-
Do not install or open the device
(e.g. for changing batteries) while
there is a risk of explosion.
Furthermore, no communication and
connection of the cables is allowed.
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 of
the pressure transmitter module!
NOTE
- Operation of the display AX16-DL01 with the EC-Type
Examination certificate IBExU12ATEX1108 X is permitted only
in combination with the accompanying pressure transmitter
(pressure sensor module) with the EC-Type Examination
certificate IBExU10ATEX 1026 U!
NOTE
- If both equipments have not been used in the
scheduled combination (display AX16-DL01 / pressure
transmitter (pressure sensor module) with certificate IBExU10
ATEX 1026 U), then the complete system has to be put
immediately out of operation!
A potentially damage of one or both devices could have been
occurred! The device(s) consequently lose the IS-certification
when using not for intended purpose!
NOTE
-
Handle the unprotected diaphragm very carefully - it is
very sensitive and may be easily damaged.
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:
- Please note that your application does not show a dew point,
which causes condensation and can damage the pressure
transmitter. There are specially protected pressure
transmitters for these operating conditions. Please contact us
in such case.
- 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
device 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 device may occur.
3.2 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.

4. Connecting display / pressure sensor module
Fig. 2 Lock against protection
Connect display with pressure transmitter module as follows:
- bring together carefully the display with pressure transmitter
module
- press the display sturdy pressure transmitter module to this
engages
NOTE
-
Before disconnecting display and pressure sensor
module make sure that the device is switched off.
NOTE

sensor module must not be disconnected!
5. Supply / changing the batteries
DANGER
Danger of death from explosion
- Do not open the housing (e.g. for
changing batteries) while an
explosion hazard exists!
Before initial start-up the insulation foil has to be removed.
Carry out steps 1 - 3 and 5 in this regard.
As soon as in the display the announcement of "battery" is
shown, a battery change is required. Follow steps 1, 2, 4,
and 5 in this regard:
1
unscrew three fixing screws with a suitable screwdriver
2
take the battery case cap
3
remove the insulation foil before initial start-up
4
exchange the batteries (3 x 1.5 V AA
5
lock the device after that properly
NOTE
- An incorrect usage may cause a leak out of batteries
and so a damage the device!
NOTE
- Use only the following batteries that have Ex and UL
approvals: 1.5V / AA DURACELL Plus Power Battery
NOTE
- Never combine batteries of different types or old
with new ones!
NOTE
- Make sure that the batteries are connected
correctly with the corresponding contacts in the battery tray.
NOTE
- Never try to charge batteries, demount them, or
short-circuit them.
NOTE
-
Keep the batteries away from heat and unshielded
flame.

7. Operation
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.
