5 Commissioning
All electrical supply, operating and measuring lines,
and the pressure connections must have been correctly installed before commissioning. All supply
lines are arranged so that there are no mechanical
forces acting on the device.
5.1 Configuration
During commissioning there are a number of setting
options that allow the device to be adapted to the
measuring point and measuring task. To facilitate
the input, the individual parameters are placed into
groups in so-called menu levels.
Depending on the device model1 some menu items
are not available. For instance, no switch points can
be set on a device without contacts.
All the device settings can be made
easily on the PC using the transmitter
PC interface. Here, the parameters are
directly visible and accessible. Also, it is
possible to load and save the entire configuration; it
can also be printed out for checking (see accessories).
presentation (see Parameter MB decimal place in
section 5.3.5).).
The unit is shown on the right of the display. If the
device is equipped with contacts, a closed contact
is always symbolised by an inverted text "SP1" or
"SP2".
Various colours can be selected for the back lighting. Depending on the measured value, the colour
of the back lighting can be automatically changed.
This can be used e.g. to depict good/poor differences. The back lighting can also be deactivated.
The measured value can also be shown in a bar
chart. The measured value is also shown in smaller
pictures as a number.
During the programming, the menu items and the
associated parameters are shown on the display.
The device continues to function whilst the parameters are being set; apart from one exception, the
changes come into effect instantly. The exception
here is a change of switching times - here the previously valid time must have run down.

5.3.1 Menu Level Switch points
The two switching outputs are configured by four
parameters respectively.
For the switch point 1 these are
Accordingly for switch point 2:
SP1 On defines the activation point, SP1 Off the
deactivation point of switch output 1. The values are
shown in the valid unit and set accordingly. The
values are shown in the valid unit and set accordingly.
Together, the two parameters determine the switch
function of switch output 1:
If SP1 Off < SP1 ON, the output switches on, if the
measured value exceeds SP1 ON. It is only
switched off again if the measured value SP1 Off is
undercut (hysteresis function).
If SP1 On = SP1 Off, the output switches on if the
measured value exceeds SP1 On and off if the
measured value undercuts SP1 Off.
If SP1 Off > SP1 ON, the output switches on, if SP1
On < Measured value < SP1 Off applies (window

Both parameters can be set independently over the

SP1 Delay allows the reaction of the switch output
1 to be delayed by between 0 and 1800 s. This value applies equally for switching on and off.
SP1 Function changes the function of the switch
output. It is possible here to define whether the contact should work as an open contact (NO) or a
break contact (NC).
5.3.2 Menu Level Input
If there are unsteady pressure readings during operation, you can use the parameters Damping and
Zero-point window to stabilise the reading (and
the output signal).
The effect of parameter Damping (on the reading,
output signal and switching points, if available, but
not on the measuring cell!) corresponds to that of a
capillary throttle. You can set the response time to
pressure jumps in the range 0.0 to 100 s. But with
maximum damping, it will take more than 2 minutes
for the reading to also reach zero after a pressure
jump from nominal pressure (100 %) to zero!
In many cases, unsteady readings are not a problem during normal operating mode, but this is not
true for the idle state, i.e. if a measured value of zero pressure is expected.
The parameter Zero-point window is designed to
solve this. Its value defines a range around zero at
which the measured value is set to zero (see fig.).
The display only stops showing zero when the
pressure leaves the set window. When twice the
window value is reached, the measuring pressure
and the display correspond again. This avoids
jumps in the display.
fore the offset correction, the zero-point window
should be set to zero.
Select the Offset correction parameter and correct
the reading using the buttons þ and ÿ until zero is
shown.
When setting the offset, the current measured value
is displayed. The zero-point window is not active
during the offset setting.
5.3.3 Menu Level Measuring
The transmitter output signal primarily depends on
the sensed pressure. However, you have the option
of adjusting the output signal to a large extent to
suit your requirements.
Note: However the basic measuring
range (indicated on the type label) and
the type of output signal (voltage / current) are not variable.
The parameters Start of measuring range and
End of measuring range initially define the two
pressures between which the output signal will
change at all. Both values are adjustable across the
entire basic measuring range. The set values also
refer to the pressure (in the respective unit). However, the signal values (current / voltage) for Start
of measuring range and End of measuring range
are fixed.
If Start of measuring range is smaller than End of
measuring range, this is called an increasing
characteristic curve; the output signal increases due
to the increasing pressure.
If End of measuring range is smaller than Start of
measuring range, this is a decreasing characteristic curve and the output signal decreases due to
decreasing pressure.
It makes sense to set the Offset (zero-point displacement) if, without pressure (remove measuring
line), the display shows a value that is not zero. Be-
6 | 16 Page
The difference between the values Start of meas-
uring range and End of measuring range must be
at least 25 % of the basic measuring range.
You can select a unit other than the unit of the basic
measuring range with the parameter Unit. The user
should remember however that not every unit is
suitable. The conversion is automatic.
The parameter Limit allows the display to be limited
to the range between Start of measuring range
and End of measuring range.
This makes sense when content is measured to
avoid "negative contents". If Limit is set to "no",
those measured values that are greater or smaller
than the end values are shown.

5.3.4 Menu Level Output
The parameters min. output, max. output and error signal define the limits of the output signal that
may not be undercut or exceeded regardless of the
pressure. The limit values take priority over the
range defined by the Start of measuring range
and End of measuring range!
These parameters primarily serve to prevent error
messages in downstream systems caused by brief
overstepping of measuring ranges.
The parameter Min. output is usually only used for
devices with an output signal 4…20 mA because
frequently values of below 3.8 mA are evaluated as
error signals. The Max. output value can be used
for the voltage and current to limit the maximum
value.
The value defined via the parameter Error signal is
issued if the device detects an internal error and
can no longer work correctly. It should be noted
here that not all potential errors and faults can be
detected by the device itself.
5.3.5 Menu Level Function
TABLE: This function allows the input in the display
and output to be freely adjusted via a table which
has up to 30 support points. Pairs of values comprising the measured value and display value are
issued for the support points.
Caution: When switching from TABLE
to another function, the table is initialised again and the existing values are
lost.
The display range is defined with the parameters
Measuring range decimal points, Start of measuring range and End of measuring range. The
user can select the configuration freely.
Using the parameter decimal place MB, it is possi-
ble to select between a 5 or 6-digit presentation.
The resolution is not increased. Only an extra zero
(in the case of 6 digits, two zeros) are added.
This serves the correct display of larger values. The
measuring range must be positive for the 6 digit
presentation.
The Unit MB gives the user the option of using a
completely independent unit. Letters, numbers or
special characters can be used. The unit can be
max. 4 characters long.
If the function TABLE is selected, then it is also
necessary to state the Number of pairs. It is defined here how many pairs of values (support points)
are used in the table. At least 3, maximum 30 support points are allowed.
The reading and the output signal can be modified
in the Function menu to meet the special requirements.
There are the following functions:
LINEAR: Linear implementation of the input on the
display and the output. The range defined in the
menu "Measuring" serves as the measuring range.
If the function LINEAR is active, the other menu
items are cancelled.
SQUARE ROOTED: Here, the input signal is
square rooted before being sent to the display and
the output. This is necessary e.g. for flow measurements with differential pressure. A free unit can
be defined for the display. To do this, the start and
end of the display range and the number of decimal
points are defined. It is also possible to define the
unit with 4 characters.
Caution: If the number of value pairs is
changed, the table is initialised again
and the existing values are deleted.
The individual value pairs can be seen and
changed with Value pair 1 to (maximum) Value
pair 30.
+0.0 mbar +0.0 %
A value pair comprises a measured value (left side)
and a display value (right side). The measured value must lie within the measuring range and the display value must lie within the defined "free unit".
The respective limits are shown during input. The
table must contain increasing values.

Menu change for colour = Auto1:
Menu change for colour = Auto2:
The parameters for influencing the display are
summarised in this menu.
The most important parameter is Colour. A fixed
background colour (red, green, yellow, blue, pink,
and turquoise, white) can be selected here. There
are also two auto-functions with colour switching
available.
Auto-function red-yellow-green (Auto2)
Note: If a range cannot be used, the as-
sociated switch thresholds can be set to
the same value.
Example:
The parameter Colour is set to Auto2. Only the
green, yellow and red ranges are required here. To
fade out the lower ranges red and yellow, the switch
thresholds "red-yellow switching" and "yellow-green
switching" are set to the start of the measuring
range.
Auto1: red-green,
Auto2: red-yellow-green.
Alternatively, the background illumination can be
permanently deactivated.
In the mode with the automatic colour switchover, it
is possible to enter the required switch thresholds
"red-yellow switchover", "yellow-green switchover",
green-yellow switchover, "yellow-red switchover" or
"red-green switchover" and "green-red switchover".
The switching thresholds can be moved within the
measuring range. The series of switch points cannot be altered.
Auto-function red-green (Auto1)

The parameter Hysteresis can be used to prevent
fast and unwanted colour changes. The hysteresis
is set in the range 0.1... 10%.
Note: In the case of large hysteresis
values, steps must be taken to ensure
that the ranges of the individual colours
do not overlap. Otherwise it is possible
that the colour change may not function in the desired way.
The parameter Delay offers a further option to prevent unwanted colour changes.

The colour change here can be delayed between
0…1800 s.
If permanent lighting is not required, the parameter
Lighting can be used to define when the lighting
should be switched off after the last time a button is
pressed. In addition to permanent lighting, automatic shut-down after 10…600 s is also possible. The
set time is only valid if the parameter Background
colour is not set to "off".
Amongst other things, the legibility of the display
depends on the temperature and the reading angle.
To ensure optimised legibility, this can be adjusted
using the parameter Contrast. When the contrast is
changed, it is possible that the display appears
empty or almost completely black. In this case, the
contrast must be turned up or down.
The parameter Bar chart is used to switch the display as follows. Either the measured value is displayed with large digits or the display uses small
digits and an additional bar chart to show the
measured value more quickly.
5.3.7 Menu Level System
Caution: The user is not able to delete
a forgotten password!
The user can load a saved configuration
via the menu item Load config. This means that a
functional set of parameters can be loaded after trying out various settings.
Note: If the user has not yet saved a
configuration, the default values (status
on delivery) are loaded. In this case, any
measuring range spreads or switch
points are reset and the device needs to be newly
configured.
The menu item Save config. serves to save the existing parameters in a protected memory area. This
is helpful if the settings of a functional device needs
to be optimised. Save config. and Load config.
can be used to quickly restore the initial status
again.
6 Maintenance
The instrument is maintenance-free.
The user menu can be switched to German, English,
French, Spanish or Italian using the parameter
Language.
The menu items Software - Info and Config - Info
provide information about the device. This information helps to answer questions about the device
quickly.
The device type, controller ID and the firmware version is shown in the software info.
The basic measuring range, the defined output signal and existing contacts are stated in the Config Info.
The Statistics provide information about the operating time and the relay switching cycles from the
time of delivery. The operating time is shown in
days (d) and hours (h)
In the menu item Password the menu can be protected with a password to prevent unauthorised
changes. The password is a figure from 1 to 999.
The input 0 means that no password is active.
The password needs to be set if the user presses
the button in normal mode to enter the menu. If a
wrong password is entered, the system automatically jumps back to normal mode again. If no password is active, the display immediately jumps to the
menu.
We recommend the following regular inspection to
guarantee reliable operation and a long service life:
• Check the reading.
• Check the function in combination with down-
stream components.
• Check the leak-tightness of the pressure con-
nection lines.
• Check the electrical connections.
The exact test cycles need to be adapted to the op-
erating and environmental conditions. If various instrument components interact, the operating instructions of all the other instruments also need to
be observed.
7 Transportation
The measuring device must be protected against
impacts. It may only be transported in packaging
specifically intended for transport.
8 Service
All defective or faulty devices should be
sent directly to our repair department.
Please coordinate all shipments with
our sales department.

Comments:
(1) Measuring values (around zero) were set to zero. (e.g. to suppress seepage).
(2): Maximum effective spread 4:1. Only the output signal is influenced.
This in turn enables a decreasing characteristic curve, if the start of the measuring range > end of the measuring range.
(3): Zero point correction for compensation of various installation positions.
