6 Operation and menu navigation
6.1 Key functions
The menu is controlled by the three keys ’Up’, ’Down’ and ’Set’, see chapter 3.2. The
following abbreviations apply to the key functions:
up Key ’Up’ press briefly
UP Key ’Up’ press for longer than approx. 2s
down Key ’Down’ press briefly
DOWN Key ’Down’ press for longer than approx. 2s
set Key ’Set’ press briefly
SET Key ’Set’ press for longer than approx. 2s
NO key combinations are used in the entire menu navigation
(one-finger menu).
6.2 Normal operation
After power on the unit, it is in the display state with the display of the last window
shown. Press SET to enter the configuration menu. From the configuration menu,
press SET to return to normal operation.
In normal operation, the pre-configured windows can be scrolled through with up or
down or automatically.
In normal mode, among other things:
•Further display windows (windows 1...10) can be selected. The respective win-
dow number precedes the heading in square brackets.
•Settings are made on the AD-VL 500 .
Since the AD-VL 500 may access external Modbus slaves for data communication, a
higher-level error monitoring of the master-slave data traffic takes place at the RS485
connection. If an error is detected, the green status information MB immediately
changes to red. Possible errors are e.g.
•Timeout: The slave does not respond. Reasons can be an incorrect slave address,
the slave is not connected or does not respond for another reason.
•Slave Exception: Reasons can be e.g. an incorrect number of data words or an
incorrect or non-existent register.
14

This visual error message is not blocking. However, due to the time monitoring of the
Modbus slaves, there may be time delays in measurement recording in the event of
failures.
For diagnostic purposes, a short keystroke (set) can be used to display a log channel
table showing all 32 log channels with the currently set up Modbus slave address and
register ([channel] address/register).
Detected communication errors are marked with a Eafter this indication. This view is
automatically updated once per second. This table can only be activated in the event
of an error.
6.3 Window navigation
The AD-VL 500 can display up to 10 display windows. Up to twelve display elements
can be shown in one window. The current window number is shown in the display
header, before the heading, in square brackets. ([1] Headline).
Figure 6.1: Scroll window
The windows can be opened, as shown in Fig. 6.1 can be scrolled up and down
either manually with the ’Up’ and ’Down’ keys or automatically with a timer. A
longer keystroke (’UP’ or ’DOWN’) in any direction initiates automatic, time-controlled
switching to the next window. This state is shown in the footer with a yellow text
Autoscroll. Switching back to manual mode is done in the same way.
The time interval for the automatic scrolling function is set with
the parameter ⇒Options ⇒Autoscroll.
The default time is 5 seconds.

7 Configuration
The unit can be configured either directly on the unit, with the Configuration software
AD-Studio (for Windows operating systems) or via the web interface. The Adam-
czewski elektronische Messtechnik GmbH provides prefabricated
unit configurations, as XML files, are available.
The USB interface converter AD-VARIO-PASS is required for the PC/device connec-
tion with the Configuration software AD-Studio .
7.1 Analogue channel setup
Each of the eight analogue channels must be assigned the physical input signal (current
or voltage). See chapter 7.2.2 on page 17.
The signal is connected to the corresponding terminals.
See chapter 9 on page 35.
Each analogue input can be scaled in its own range to display and log scaled quantities.
The scaling does not yet contain a unit here. A scaling unit is set up directly on the
log channel (1...32).
Each analogue input signal can be linearised with a linearisation function or a global
linearisation table, by a function assignment characteristic. The linearisation table,
with 24 interpolation points, contains the physical input variable (mA/V) as the input
value and a numerical value as the output value.
See example in the web interface, chapter 10.10 on page 44.
The linearisation is done by interpolation between the interpolation points.
The linearisation of the different tank shapes, round tank (idealised) or spherical tank,
is done according to a calculation formula.
The signal normalisation is realised by a multiplication of linearisation and scaling.
7.2 Configuration menu
In the configuration menu, various configuration items can be selected on the
AD-VL 500 . If a configuration item requires a numerical index, the index selection
is activated and queried. The index setting is made by means of a rolling number,
which is set with the navigation keys. The numerical index is then shown in the menu
heading in square brackets.
Example: Configuration item [1].
7.2.1 Device information
Under device-information, various information on the status
of the AD-VL 500 is displayed. Available memory sizes of the mounted data carriers
are displayed here. A clear representation can also be found on the HTML status page
(see chapter 10.7.1 on page 42).
16

7.2.2 Analogue inputs
Only the parameters of the analogue functions are set in this area.
The Analogue Inputs menu branch contains the following submenu branches:
•Signal type I / U
•Characteristic linear, round tank, spherical tank, table
•Measuring range Lower range value, upper range value
•Scaling Scaling start, scaling end
•Filter XXX s
•Counter Counter reading, switching threshold, pulse factor, pulse divider
The following parameters are available for configuring the analogue inputs.
Parametername Default value Range Unit
Signal type I I / U
Characteristic linear linear, round tank,
spherical tank, table
Measuring range 0...20 lower range value,
upper range value
mA
Filter 0 0 ... 999
Counter, counter

Counter,
Switching threshold
1,2 / 2,1 Messbereich mA
Counter, Pulse factor 0...10000 0
Counter, Pulse di-
vider
1...100000 1
The digital levels that control the counters are derived from the set-up counter switch-
ing thresholds. The corresponding values can be read on their own Modbus registers.
See chapter 8.2 on page 33.
For level detection, an analogue value must have safely reached the switching threshold
and assume a stable state for at least two seconds.
When using the voltage inputs as pulse inputs, voltage values up to 25 volts are per-
missible. However, they are only recorded analogue up to 10 volts.
An adjusted filter leads to an extension of this stabilisation phase.
With pulse factor and pulse divider the incoming pulses can be evaluated
(Count value = Input pulse x Pulse factor / Pulse divider).
The count values can only be saved automatically once per hour, in a non-volatile
memory (EEPROM). All values accumulated within one hour are lost in the event of
a supply voltage failure.
Direct editing of the linearisation table on the AD-VL 500 is NOT
provided. The table can be edited and transferred to the unit via
the web interface or the Configuration software AD-Studio .
Finished tables can be exchanged via the import and export func-
tions using a USB stick.
17

7.2.3 Windows
The Window menu branch contains the following submenu branches:
•Display elements
•Show
•Labelling
•Index display element
The following parameters are available for configuring the windows.
Parametername Default value Range Unit
Number of
display elements[N]
8 1 ... 12

Labelling[N] ’xyz...’ 1 ... 30
Index display element
[N.1]
1 ... 40
...
Index display element
[N.12]
1 ... 40
With [N] as window number (1 ... 10).
The parameter Number of display elements[N] determines the number of display
elements that are shown in this view. With the parameter Show determines whether
the display is shown or not, this can be used to show or hide a parameterised display,
e.g. temporarily or system-specifically. With Index display element[N.1] ... Index
display element[N.12] the indices of the display elements to be shown are determined.
Example: Index display element[2.5] = 3 means that the third display element is used
as the fifth element of the second window.
7.2.4 Display elements
Up to 40 different display elements can be configured to show measured values within
the display windows. A display element contains all the information for displaying a
value from a logical log channel (1...32). It can be used in different windows, even
multiple times.
The Display Elements menu branch contains the following submenu branches:
•Show
•Scaling
•Color change
•Switching threshold
•Labelling
•top
•left
•Height
•Width
•Font size
18

•Orientation
•Standard color
•Alternative color

[N] is the 1-based index of the display element [1...40].
With the parameter Show[N] the type of presentation can be selected.
The parameter color change function[N] determines whether and after which func-
tion the alternative color is used to represent the value from the channel.
The switching points define the limit values for the color change function.
They have the same unit as the value of the channel.
19

The parameter Label position[N] sets the position of the label relative to the display
element.
The parameter top[N], left[N], Height[N], Width[N] define the position and size
of the display element within the representation area of the display.
The parameter Standard color[N], Alternate color[N] the colors determine how
the value is displayed.
The parameter Index channel[N] determines the channel to be displayed.
The parameter Interval is only used as a time grid for a set-up time diagram.
The label and unit are automatically taken from the associated
log channel.
The switching points and the alternative color are only evaluated
if a color change function has been selected, i.e. ’Hysteresis’ or
’Window’. The color change function is evaluated cyclically. If
the return value is true, the display element uses the alternative
color to represent the value.
Numerical display
In the numerical display, the value of the channel is shown together with the label and
the unit.
The number of decimal places is set in the parameter Numeric[N] (0...4)
