3.1 Mounting and safety instructions
WARNING! Install the device only when depressurized
and currentless!
WARNING! This device may only be install ed by
qualified technical personnel who has read and understood the operating manual!
DANGER! Explosion hazard, with devices for oxygen
applications, when used improperly. To ensure a usage
without danger, the following points must be adhered to:
- Make sure, your device has been ordered and delivered as a special version for oxygen applications. You can check the manufacturing label (see
figure 1). If the ordering code ends with "007", then
the device is suitable for oxygen applications.
- At time of delivery the device is packed into a plastic bag in order to prevent it from impurity. Please
observe the indication label "Device for oxygen,
unpack only directly before assembling". Also,
avoid any skin contacts during unpacking and assembly, in order to prevent greasy residues on the
device.
- During installation, the respective explosion protection regulations have to be met. Check, if ATEXapproval is necessary for this type (oxygen) device.
(the delivered device has no ATEX-approval)
- Note the entire design requirements meet the
standard demand of BAM (DIN 19247).
- For devices with oxygen capability up to 50 bar, orings V747-75 with BAM-approval are being used.
The max. capabilities allowed, are 40 bar/130° C
and 50 bar/100° C.
- For devices with oxygen capability over 50 bar, orings FKM 90 are being used. These have been
tested up to 95° C and 215 bar in the scientific coal
research institute in Ostrava – CZ.
!
Handle this high-sensitive electronic precision
measuring device with care, both in packed and
unpacked condition!
!
There are no modifications/changes to be made on the
device.
!
Do not throw the package/device!
!
To avoid damaging the diaphragm, remove packaging
and protective cap only directly before starting up the
device. A delivered protective cap must be stored!
!
Place the protective cap on the pressure port again
immediately after disassembling.
!
Handle the unprotected diaphragm very carefully - it is
very sensitive and may be easily damaged.
!
Do not use any force when installing the device to prevent damage of the device and the plant!
!
For installations outdoor and in damp areas following
these instructions:
- To prevent moisture admission in the plug the device should be installed electrically after mounting,
at once. Otherwise a moisture admission has to be
blocked e.g. by using a suitable protection cap.
(The ingress protection in the data sheet is valid for
the connected device.)
- Choose an assembly position, which allows the
flow-off of splashed water and condensation. Avoid
permanent fluid at sealing surfaces!
- When using a cable gland device, turn the outgoing
cable downwards. If the cable has to be turned
upwards, then point it downward so the moisture
can drain.
- Install the device in such a way that it is protected
from direct solar irradiation. Direct solar irradiation
can lead to the permissible operating temperature
being overstepped in the worst case. By this the
operability of the device can be affected or damaged. If the internal pressure i ncreases due to solar irradiation, measurement errors may be caused.
!
For devices with gauge reference in the housing (small
hole next to the electrical connection), install the device
in such a way, that the gauge reference is protected
from dirt and moisture. Should the device be exposed to
fluid admission, the functionality will be blocked by the
gauge reference. An exact measurement in this condition is not possible. Furthermore this can lead to damages on the device.
Take note that no assembly stress occurs at the
pressure port, since this may cause a shifting of the
characteristic curve. This is especially important for very
small pressure ranges as well as for devices with a
pressure port made of plastic.
In hydraulic systems, position the device in such a way
that the pressure port points upward (ventilation).
Provide a cooling line when using the device in steam
piping.
If installing the device outdoor and there is any danger
of lightning or overpressure we suggest putting a
overpressure protection unit between the supply/switch
cabinet and the device to prevent damage.
3.2 General installation steps

6. Operation
6.1 Operating and display elements
LED
contact 1
▼-button ▲-button
Fig. 2 touchpad for device with two contacts
The device has, according to the order max. two LEDs which
are allocated to the resp. contacts. The LEDs will light up
when the respective set point has been reached and the
contact is active. The display of the measured value as well
as the configuration of the individual parameters occurs
menu-driven via the seven-segment display.
6.2 Configuration
The menu system is a closed system allowing you to scroll
both forward and backward through the individual set-up
menus to navigate to the desired setting item. All settings are
permanently stored in an EEPROM and therefore available
again even after disconnecting from the supply voltage. The
structure of the menu system is the same for all types of
devices, regardless of the number of contacts. However,
they only differ by the number of menus. Following figure and
the menu list shows all possible menus. On devices with
3-wire output 4 ... 20 mA and 0 ... 20 mA, the menus ZP and
EP have special functions. The menu DP is not applied, as
the decimal point is already factory set during production.

Please follow the manual meticulously and remember
that changes of the adjustable parameters (switch-on
point, switch-off point, etc.) become only effective after
pushing both buttons simultaneously and leaving the
menu item.
!
Pay attention that no moisture can enter the device
during configuration. Moreover, the seals and the sealing surfaces should not get dirty, as this may cause a
reduction of the degree of protection depending on the
case of application or place of installation. This can lead
to a breakdown of the device or to irreparable damages
on the device. Right after configuration, the metal cap
has to be screwed on again.
6.3 Password system
To avoid a configuration by unauthorized persons, the
possibility is given to lock the device by an access protection.
More information is given in menu 1 of the menu list.
6.4 Configuration example of the analogue output for
3-wire devices
By the menus ZP and EP, the analogue output for 3-wire
devices (4...20 mA and 0...20 mA) can be configured. In the
following, the function of these menus shall be made clear by
an example: assuming you have a pressure switch with a
nominal pressure range 0 ... 400 bar with an analogue signal
of 4...20 mA / 3-wire. By factory the following performance is
set:
0 bar = 4.00 mA 200 bar = 12.00 mA 400 bar = 20 mA
If you change the value in the menu ZP from 0 to 20 and the
value in the menu EP from 400 to 300, the following performance will appear:
20 bar = 4.00 mA 160 bar = 12.00 mA 300 bar = 20 mA
The values of ZP and EP are adjustable up to 1:6 of the
nominal pressure range.
6.5. Description of hysteresis and compare mode
To invert the respective modes, you have to exchange the
values for the switch-on and switch-off points.

PAof password inactive to activate: set password
default setting for the password is "0005"; modification of the password is described in special menu 4
menu 2 – set decimal point position (only 2-wire-system)
for devices with 3-wire output 4 ... 20 mA and 0 ... 20 mA the decimal point was already set during production
menu 2a – indication of the starting point, which was defined with the order (only 3-wire-system)
no configuration is possible
menu 2b – indication of the end point, which was defined with the order (only 3-wire-system)
no configuration is possible
the device has been configured correctly before delivery, so a later setting of a 2-wire device is only necessary, if a
differing displayed value is desired (e. g. 0 ... 100 %)
For devices with 3-wire output 4 ... 20 mA and 0 ... 20 mA this menu has a different meaning: The configuration of the zero point causes a changing of the analogue output, whereas the display value remains unchanged. (zero and end point can be configured within the limits of the nominal pressure range, according to
the manufacturing label); for more information see "6.4 Configuration example of the analogue output for 3wire-devices"
this function allows getting a constant display value although the measuring values may vary considerably; the time
constant for a simulated low-pass filter can be set (0.3 up to 30 sec permissible)
set "on" or "off"

(0 up to 100 sec permissible)
view high pressure (HIPr) or low pressure (LoPr) during the measurement process
(the value will not remain stored if the power supply is interrupted)
to erase: push both buttons again within one second
set the length of the update cycles for the display (0.0 up to 10 sec permissible)
with the ▲- or ▼-button the contacts 1 (tES1) or 2 (tES2) can be activated or deactivated
select one of the following settings: "oi 4" (4 mA or 2 V), "oi12" (12 mA or 6 V) and "oi20" (20 mA or 10 V)
(to access a special menu, select the menu item "PAof" with the ▲- or ▼-button and confirm it; "1" appears in the display)
set the desired error signal (this is given out in case of a defect); permissible settings are "OFF" (no error signal
output), "C 0" (0 mA or 0 V), "C L0" (3.5 mA or 1.75 V) and "C HI" (23 mA or 11.5 V)
an output of the error signal is only given when menu 6 is set on "on"
confirm menu item "P0SI"; if offset ≠ ambient pressure it is necessary to place the device under pressure (pressure
reference has to corresponding to the zero point of the pressure measuring range); push both buttons to store the
signal being emitted from the pressure switch as offset; in the display the set zero point will appear although the
sensor signal in the offset is displaced
a position correction is necessary, if the installation position differs from the calibration position (otherwise this
can cause a little deviation of the signal, which gives a wrong value indication)
the analogue output signal (for devices with analogue output) is not affected by this change;
when displacing the offset, the full scale will also be displaced
to load the defaults, push both buttons simultaneously, after confirming the menu item
any changes carried out will be reset (password will be set on "0005")
to load a stored configuration (via menu 39), set the desired number 1 up to 5
to store a configuration, set the desired number 1 up to 5
for full scale compensation, which is necessary if the indicated value for full scale differs from the real full scale
value in the application (a compensation is only possible with a respective reference source, if the deviation of the
measured value is within defined limits); set "0238"; confirm with both buttons; "FS S" will appear in the display; now
it is necessary to place the device under pressure (the pressure must correspond to the end point of the pressure
measuring range); push both buttons, to store the signal being emitted from the pressure switch as full scale; in the
display the set end point will appear although the full scale sensor signal is displaced.
the analogue output signal (for devices with analogue output) is not affected by this change
set "0247"; the menu description is identical with menu "P0SI" (menu 24) for 3-wire-devices
set "0729"; the menu description is identical with menu "FAct" (menu 25) for 3- wire-devices
set "0835"; confirm with both buttons; "SEtP" appears in the display; set the password using the ▲- or ▼-button
(0 ... 9999 are permissible, the code numbers 0238, 0247, 0729, 0835 are exempt); confirm the password by
pushing both buttons simultaneously
7. Placing out of service
WARNING! When dismantling the device, it must
always be done in the depressurized and currentless
