1.1 Function description
The flowscreen analysis system is designed and produced for the monitoring of dosing
processes. Up to two pressure sensors can be attached. The pressure values determined
from the measurement signals are shown on a graphic display.
The start of a measurement can be set either at pressure build-up or after creating a start
signal. The raw data from the attached sensors are defined using the calibration function.
The display can be adapted for the current application in the view for the axes of pressure
and time.
A fault message is indicated via a LED if the determined limits for pressure increase,
pressure gradient during dosing and pressure reduction are exceeded. An error tolerance
number can be set for each attached sensor.
1.2 General information on the menu guide / operation
The flowscreen analysis system is operated via a touch screen using the stylus provided.
The operating menu is largely self-explanatory. System states are depicted via symbols
and plain text.
1.3 Description of software operation
In order to ease legibility, details on using the software interface that are considered too
basic are not described.
If for example, a certain button must be pressed, the generally understandable
information is not mentioned, with the necessary action and logical result described in
brief.

3.5.5 Setting Range operating mode
General
The settings are possible if the Range operating mode is switched on (see 3.5.4). The
pressure gradient of a dosing (1) can be monitored and displayed for each connected
sensor with three different measurement ranges (see Fig. 4).
The dosing is judged to be error-free if the pressure gradient (1) of the dosing (as shown)
is within the tolerances determined by ranges A, B and C.
In the event of an error, the error LED (9) illuminates if the set error threshold has been
reached.
The measurement starts (adjustable for each sensor) either when a pressure threshold
is reached or via a signal applied to the system plug (4) (see 3.5.2).
Monitoring of the three measurement ranges can activated and deactivated individually
for each sensor.

The measuring range of the pressure build-up range (A) is
determined via Box1. The values are defined as follows:
- 1 = Left
- 2 = Right
- 3 = Top
- 4 = Bottom
Note
Unrealistic values are corrected. If no box appears in the
display, it may be outside of the display window (diagram area),
to adjust this, see 3.5.3.

• In the same display (Limits, perform three dosings. The measurement range B will be
automatically calculated from the entered data and shown on the display when the the
third measurement is completed. The measurement range for the pressure gradient
(envelope curve) is saved.
Note
The Envelope Curve must be recalculated if one of the parameters for the Envelope
Curve is changed.
The envelope curve is deleted in the event of an interruption of the power supply.

3.5.6 Setting Overpressure operating mode
General
The settings are possible if the Overpressure operating mode is switched on (see 3.5.4).
A overpressure value (2) can be monitored and displayed for the pressure gradient (1) of
the dosing for each connected sensor.
• <Settings> <Limits>
• Set or activate Limit Overpressure for the respective sensor. The overpressure
value (2) is displayed during a measurement.

3.6 Performing measurements
Measurement operation requires the settings from the following sections:
- 3.4, Starting up
- 3.5, Base settings
The flowscreen analysis system is then ready for operation (to switch on, see 3.3). If
envelope curves have been saved (see 3.5.5), these must be reset every time after
switching on.
Notice: The following description applies to both sensor inputs, which can each be
configured differently from each other.
Measurement display
The pressure / time gradient of each measurement (pressure curve) is shown on the
display.
Error display
If one or more of the set values / tolerances is exceeded in a measurement, this is shown
optically (red)
Error counter
The error counter increases by a value of 1 each time an error occurs. The error LED
illuminates as soon as the set threshold value is reached.
Error-free dosings increase the respective counter in the same way.
Error reset
<Reset Counter> (diagram view) ►Error counter is reset to 0. At the same time, the
counter for error-free measurements is also reset to 0. All counters can be shown via
<Settings><Results>.
3.7 Switching off
Move the on/off switch to the OFF position to switch off the flowscreen analysis system.
