Measuring Transducer AD-MW 200 ST
Descrtption:
All standard signals (0-20mA / 4-20mA / 1-10V) can be highly linear
converted and amplified from each other with the measuring
transducers of the AD-MW 200 ST family. The measuring signal
can be adapted to the current measuring situation by means of
trimming potentiometers positioned on the front side. The supply
voltage is separated galvanically from the measuring signal and is
possible within a wide range from 20-30V AC or DC. Because of
this internal galvanic separation, it is also possible to operate
several measuring transducers from only one supply voltage. An
economical alternative to isolation amplification when a galvanic
separation of the output is not technically relevant.
Application:
Technical data:
Acquisition, linear conversion and a high degree of amplification of
industrial standard signals in small plug module technology with the
possibility of measuring value corrections with a large voltage supply
range. Economical possibility for the conversion of already
galvanically separated signal sizes.

Descrtption
The measuring value amplifier AD-MV 50 GL (for 2/3 lead technology)
or AD-MV 54 GL (for 4-lead technology only) converts the measuring
signal issued from a resistance generator Pt-100 (according
to DIN IEC 751) to an impressed output signal (i.e. 0-20 mA or similar).
The output characteristic curve is issued temperature linear.
When using the 3-lead switching lead, resistance up to 100 Ohms
are compensated. In 2-lead switching a subsequent zero alignment
and full alignment via trim potentiometers at the front is possible.
The analogue output signal is galvanically separated from the
supply voltage.
A highly efficient, integrated electronic wide-range power pack
(ALLPOWER) enables operation with 20-253 V AC or DC. There is
no possibility of cross polarity of the connection voltage. A high
packing density is achieved due to its narrow build.
Application
Specification
Due to the use of a high quality electronic power pack, no strong temperature
increase occurs. The housings do not have to be fitted at a
distance from each other.

Special functions of the multi-measuring transducer
?
VarioCheck VC3
For instance: ...the simulation mode
In simulation mode, the VC 3 GVF offers the possibility to specify the scaled value manually. This possibility
is, for instance, an important aid during commissioning, if no measuring values, or not the required measuring
values, from the process exist yet. All other device functions, such as limiting value editing and analogue output,
continue to function without limitation, as if the scaled value is derived from the measuring value. This
characteristic can also be utilised, for instance, to specify the nominal value on the analogue output.
For instance: ...the linearizing of characteristics
A free table with 24 x/y value pairs is available for characteristics linearizing. During this, it is very helpful that
the Y-values are entered already in scaled values. The characteristics data for a horizontal cylinder and a ball
container are already completely entered and have only to be activated.
For instance: ...the diversity of the limiting value functions
The limiting value functions can be set separately for each individual relay. Whether hysteresis function or
window function, time delays can also be defined singly for each operating mode. Also, the mode of
action of the relays can be adapted to the application.
For instance: ...the user-friendly operation
The device is equipped with three short-stroke keys at the front for operating, for display of the measuring
value and the parameter in a graphic display with clout background lighting and a communication interface
for configuration via a PC. The menu language can be defined directly in the device, the colour of the display
immediately indicates the operating mode or errors and with the PC-interface, the documentation of the complete
configuration is ensured.
For instance: ...the functional housing
With a width of only 33 mm and the proven clip foot, the device can be easily mounted. And with the standard
clamps, which can be pulled off, it can be clamped on without problems. The clear hood protects the device
against contamination and uncontrolled reconfigurations of the operating indicator.

Function and applications
The digital multi-function measuring transformer of series VarioCheck VC 3 GVF are
freely programmable digital measuring transformer with two analogue outputs and up
to 4 limiting value relays. Alternatively, a bipolar voltage of up to 10 V, a bipolar
current of up to 20 mA or a potentiometer in three-wire method is possible as input
signal. Additionally, a a supply for 2 or 3 wire transmitter is integral. The inputs are
galvanic separated from the auxiliary voltage and from the outputs. The two analogue
outputs can be utilised simultaneously.

Adamczewski GmbH Operating Instructions VC 3 GVF
Operation
The device is operated with the three keys, ?up“, ?down“ and ?set“. There are no
combinations of keys, which have to be pressed simultaneously. The keys are pressed
one at the time. The key function depends on the current operating mode. It is
differentiated between a short and a long key pressure. A long key pressure is
recognised after approx. 2s. Therefore, in the following, pressing the key means
pressing the key briefly, key pressure > 2 seconds means a long pressure.
Key Function
?up“ In normal operation, pressing this key returns you to the previous
display. In parametrising you navigate with this to the previous menu
element. When editing a parameter, the previous list element, or when
incrementing a digit, the selection is made with this key. The current
display is scrolled or the current parameter is incremented with a long
key pressure.
?down“ In normal operation, pressing this key takes you to the next display. In
parametrising you navigate to the next menu element. When editing a
parameter, the next list element, or decrementing a digit, the selection
is carried out with this key. The current display is scrolled or the
current parameter is incremented with a long key pressure.
?set“ In normal operation, pressing the key switches on the lighting. A long
key pressure changes to parametrising. In parametrising, the selected
element is selected with pressing the key. A long key pressure returns
you to the normal operation. During editing, pressing the key confirms
the selected list element or the edited digit. A long key pressure
returns you to parametrising.
The operating modes
The device is always in one of these operating modes, which are explained in more
detail in the following.
● Normal operation
● Menu
● Edit
● Error indicator
● Simulation
Operating mode normal operation
After switch on, the device is in normal operation and carries out all functions set in its
parameter. The indicator lighting is blue and goes off after approx. 2 minutes in
standard setting, if no other key has been pressed. The first line contains the heading,
the last line contains status information about relays and input signal. With a long key
depression, the device changes to operating mode parametrising. With the keys ?up“
and ?down“ you can switch between the following display views.

The status line
The last line in the display contains status information for the relays and the signal
condition. The max. four relays are marked with the capital letters 'A'..'D'.
Mark Meaning
1-4 ● 'N' Relay N is activated (also Relays 'A', 'B', 'C' or 'D')
● 'n' Relay N has been activated (indication only when the parameter
?save“ has been set to ?yes“ for this relay). Through pressing the
key ?set“, the flag can be deleted again.
● '-' Relays N is not activated.
● ' ' Space. No relay exists for this type of device.
5 ● In normal operation, the status of the measuring signal is shown
here. Arrow up/down ' ', ' ' shows that the measuring signal has ▲ ▼
exceeded/fallen below the set input measuring range. This indicator
is empty in the valid range.
● 'S' is shown in simulation modus. Exceeding of the measuring range
is not possible here.
Operating mode menu
A long depression of the key ?set“ takes you from normal operating mode to operating
mode menu. The indicator lighting is yellow. In the menu tree you can navigate up
and down with the keys ?up“ and ?down“. With pressing the key ?set“ the elements
are selected. This can be a parameter, a further sub-menu or also a device function,
such as contrast setting. Each menu offers as last entry the possibility to return to the
previous menu. The last entry is marked with an arrow to the left ?<“ (see also section
?The menu tree“). A long depression of the key ?set“ returns you to normal operating
mode. If no entry is made for approx. three minutes, you are also branched to the
normal operating mode.
Operating mode edit
Selecting a parameter with a short depression of the key ?set“ takes you from the
menu to the edit modus. The indicator lighting is white. Altered parameter become
effective immediately. If no entry is made for approx. three minutes, you are branched
to the menu again.
Parameter Indicator image Comment
Numeric
parameter
The current digit, which can be edited, is shown
inverse and can be incremented or
decremented with the keys ?up“ and ?down“.
When the last edited digit is confirmed with
?set“ and the digit has passed the data check,
the parameter is taken over. A long depression
on the key ?set“ cancels the entry and returns
to the menu.
Lists The current list element is shown inverse and
can be altered with the keys ?up“ and ?down“.
If the current list element is confirmed with the
key ?set“, the selected entry is taken over. A
long depression on the key ?set“ cancels the
entry and returns to the menu.

Device functions
Filtering the input signal
The input signal is transformed to a digital value via an analogue digital transducer
and is filtered digital prior to any further processing. The raw value of the A/Dtransducer
is filtered during each programme through-run with the following function:
Xt=
XtX t?1?F?1
F
whereby X is the A/D-transducer value, t is the time of the current measuring, t-1 is
the time of the last measuring and F is the filter value. For the VC 3 GVF, the following

Scaling and characteristic line
The analogue input can be scaled on a user-defined capacity for indication and for
entering defined parameter. The switch points of the limiting values, the simulation
range, the simulation increment and the Y-values of the user characteristic line are
shown scaled and entered. With linear scaling, the scaling range form the scaling
parameter is used. With non-linear scaling, either the user-defined characteristic line
or one of the fixed characteristic lines is used. The following parameter must be
observed (Yes) or they are not important with this (No).

Linear scaling
The following example shows the connection between analogue input, scaled quantity
and the analogue output with linear scaling.
Application: filling level measuring in a 5000 litre tank with an immersion probe
4..20mA. At the measuring range start of 4mA, there is a remaining quantity of 100
litres in the tank. With 5000 litres, the probe current is 18mA. The output is to be l
4..20mA.
Settings: input current input 0..20mA or 4..20mA; measuring range 4..18mA; scaling
range 100..5000; scaling unit ?l“; scaling decimal point ?xxxx“ (no decimal point)
Measuring: first, convert the measuring signal of 7.4mA to the scaled quantity. This
results in a value of 1290l. This value is now converted onto the output, whereby this
results in an output current of 7.9mA.
Note: If the measuring signal falls below or exceeds the set measuring range of
4..18mA, the scaled value, and therefore also the output, is connected to the starting
value or end value.

Non-linear scaling via the user characteristic line
The following example shows the connection between analogue input, scaled quantity
and the analogue output with non-linear scaling via the user characteristic line.
Application: filling level measuring in a 4500 litre tank with an immersion probe
4..20mA. At measuring range start of 4mA, a remaining quantity of 150 litres is in the
tank. At 4500 litres, the probe current is 17mA. The output is to be 4..20mA. The
characteristic line has been ascertained through the following value pairs.
Input/mA Volume/l
4 150
10 1350
13 3850
17 4500
Settings: Input current input 0..20mA or 4..20mA; the setting of the measuring range
and the scaling range is not applicable, as values from the characteristic line are
interpolated; scaling unit ?l“; scaling decimal point ?xxxx“ (no decimal point); number
of characteristic line points 4; points according to table.
Measuring: First, the measuring signal of 7.4mA is interpolated from the characteristic
line. This results in a scaled value of 830l. This value is now converted linear to the
output, whereby this results in an output current of 6.5mA.
Note: if the measuring signal falls below or exceeds the first or the last value from the
table, the scaled value, and therefore also the output, is connected to the starting
value or end value.

Non-linear scaling via a fixed characteristic line
Apart from the user-defined characteristic line, fixed characteristic lines can be used
for predetermined applications. The characteristic of this characteristic line, in contrast
to the user-defined characteristic line, is connected in the selected input measuring
range. The following fixed characteristic lines can be set via the parameter
characteristic line modus.

Function
?Cylin“ Filling level calculation via the filling level h of a horizontal cylindrical
round tank with radius r. The filling level is specified typically
through a pressure transmitter. The characteristic of the
characteristic line is determined through the surface of the circular
segment and connected between the measuring range start and the
measuring range end. The length of the tank l results indirectly from
the tank volume, which is specified as scaling end.

Limiting value function
The limiting value function can be set for each single relay. The terms ?active“ and
?passive“ or ?not active“ refer to the logic of the limiting value function. Whether the
relay responds or releases during activated function depends on the setting of the type
of action for this relay. Here, full-load current means responded with activated function
and not responded with not activated function. With closed-circuit current the reverse
is true.
Hysteresis function
The hysteresis function becomes active when the measuring value has exceeded the
upper switch point and the switch-on delay tvon has expired. It becomes passive
again when the measuring value falls below the lower switch point and the switch-off
delay has expired.
Window function
The window function becomes active when the measuring value lies between the
upper and the lower switch point and the switch-on delay time tvon is expired. It
becomes passive again when the resuming value falls below the lower switch-point or
the upper switch point is exceeded and the switch-off delay is expired.

Trend function
The trend function shows the trend of the input signal over time. For this, the present
measuring value is frozen at certain intervals, the trend time, and at the end of the
trend time, the frozen value is compared to the current measuring value, plus or
minus a parametrisable trend difference. This comparison results in a rising, falling or
invariable trend.
rising trend=datatdatat?trend timetrend rising
falling trend=datat datat?trend time?trend falling
otherwise
constant trend
In normal mode, the trend can be read off in the display for the input signal and the
scaled input signal in the unit line left, underneath the numerical value of the signal.
The arrow up ?▲“ means rising signal trend, the arrow down ?▼“ means a falling signal
trend and the equal sign ?=“ means an invariable signal trend. For parametrising the
trend function, three parameter are available, ?Trend time“, ?Trend rising“ and ?Trend
falling“. The trend information rising, falling or invariable signal can also be displayed
through the relay outputs. For this, the relay function of the corresponding entry must
be selected from the list. Each relay can take on a different relay function, for
instance, relay A can show the rising trend, relay B can show the invariable trend. The
function invariable trend in connection with a long trend time can be utilised for
monitoring a sensor, to monitor signal standstills, i.e. with stuck mechanical
transmitters. In the illustration, relay A is configured for display of rising trends and
relay B is configured for display of an invariable trend. Note: The trend information is
only determined at the end of the trend time. With long trend times, this can possibly
lead to confusion, if the trend of the monitored signal reverses several times during
the trend time, when the trend of the last interval is still displayed.

Simulation
In simulation mode, the VC 3 GVF offers the possibility to specify the scaled value
manually. This possibility is an important aid, for instance, during commissioning,
when there are still no, or not the required, measuring values available from the
process.
Note: All other device functions such as limiting value, editing and analogue output
remain functioning without limitation, as if the scaled value had been derived from the
measuring value. This characteristic can be utilised very well, for instance, for the
nominal value specification at the analogue output.
Setting the simulations parameter
To set the simulation parameter, the parameter from the simulation menu must be
checked or altered. Set the simulation modus to ?Temp“, when the simulation mode is
to be cancelled automatically after approx. 3 minutes and the device returns to normal
mode. Set the simulation modus to ?Const“ when the simulation mode should remain
permanently switched on.
The limits for the simulation value are set with the simulation range. The increment
determines the increment, around which the manual or automatic
incrementing/decrementing is carried out. The time slot pattern specifies in seconds
the interval during automatic incrementing/decrementing.
Note: The simulation modus is saved non-volatile. After switching the device off and
then on again, it is still in simulation modus!
Starting Simulation
After the simulation modus has been set to ?Temp“ or ?Const“, long depression of the
?set“ in the menu. Instead of changing to the normal mode, the device now goes into
simulation mode and displays the scaled value.
Note: the last value from the normal mode is taken over as starting value in
simulation mode.
Specifying the simulation values manually.
Starting with the start value, the simulation value is increment or decrement by the
increment through pressing the key ?up“ or “down“.
Shutting the simulation values down automatically as ramp
With a long pressure on the key ?up“ or “down“, the simulation value in the specified
time slot pattern is automatically incremented or decremented. If the simulation value
has reached the end or the beginning of the simulation range, the direction reverses
automatically. The automatic mode can be ended again with pressing the key ?up“ or
?down“.
Stopping the simulation
The simulation can be stopped through setting the simulation modus in the simulation
menu again to ?off“. If the simulation mode is set to ?Temp“, the function stops
automatically after approx. 3 minutes.

Special functions of the multi-measuring transducer
?
VarioCheck VC5
For instance: ...the simulation mode
In simulation mode, the VC 3 GVF offers the possibility to specify the scaled value manually. This possibility
is, for instance, an important aid during commissioning, if no measuring values, or not the required measuring
values, from the process exist yet. All other device functions, such as limiting value editing and analogue output,
continue to function without limitation, as if the scaled value is derived from the measuring value. This
characteristic can also be utilised, for instance, to specify the nominal value on the analogue output.
For instance: ...the linearizing of characteristics
A free table with 24 x/y value pairs is available for characteristics linearizing. During this, it is very helpful that
the Y-values are entered already in scaled values. The characteristics data for a horizontal cylinder and a ball
container are already completely entered and have only to be activated.
For instance: ...the diversity of the limiting value functions
The limiting value functions can be set separately for each individual relay. Whether hysteresis function or
window function, time delays can also be defined singly for each operating mode. Also, the mode of
action of the relays can be adapted to the application.
For instance: ...the user-friendly operation
The device is equipped with three short-stroke keys at the front for operating, for display of the measuring
value and the parameter in a graphic display with clout background lighting and a communication interface
for configuration via a PC. The menu language can be defined directly in the device, the colour of the display
immediately indicates the operating mode or errors and with the PC-interface, the documentation of the complete
configuration is ensured.
For instance: ...the functional housing
With a width of only 33 mm and the proven clip foot, the device can be easily mounted. And with the standard
clamps, which can be pulled off, it can be clamped on without problems. The clear hood protects the device
against contamination and uncontrolled reconfigurations of the operating indicator.
