1. Short description
2. Assembly
The panel instrument UDA 50 is a 4-digit display for direct voltage / direct current signals and a visual limit
value monitoring via the display. The configuration happens via three front keys or via the optional PC-
software PM-TOOL. An integrated programming lock prevents unrequested changes of the parameter and
can be unlocked again via an individual code.
The electrical connection happens on the rear side via plug-in terminals.
Selectable functions like e.g. the query of the min/max value, a zero point calming, a direct limit value
adjustment in the operating mode and additional measuring support points for linearization complete the
modern device concept.

4. Function description and operation
Operation
The operation is divided into different levels.
Menu level
Here it is possible to navigate between the individual menu items.
Parameterisation level:
The parameters stored in the menu item can be parameterised here.
Functions that can be adjusted or changed are always indicated with a flashing of the display. Adjustments
made at the parameterisation level should be always confirmed by pressing the [P] key to save them.
However, the display automatically saves all adjustments and then switches to operation mode if no further
keys are pressed within 10 seconds.
Menu level Parameter level
Example:
4.1. Programming via configuration software:
Included with the software on CD, is a USB cable with device adapter. The connection is made via a12-pin
micromatch connector on the back of the device and to the PC side with a USB connector.
System requiremets: PC with USB-interface
Software: Windows XP, Windows VISTA
With this tool the device configuration can be generated, omitted and saved on the PC. The easy-to-use
program interface allows the parameters to be changed, with the mode of operation and the possible selection
options being specified by the program.
ATTENTION!
During parameterisation with connected measuring signal, make sure that the measuring signal has no mass
supply to the programming plug.
The programming adapter is galvanic not isolated and directly connected with the PC. Reversing the polarity
of the input signal can cause a current to flow through the adapter and destroy the device and connected
components!

5.1. Switching on
After completing the installation, you can put the device into operation by applying the supply voltage. Check
all electrical connections once again beforehand to ensure that they are connected correctly.
Starting sequence
During the switch-on process, the segment test (8 8 8 8), the message of the software type and subsequently the
software version are displayed for 1 second for the same time. The start sequence is followed by the change
to the operating or display mode.
5.2. Standard parameterisation:
To be able to parameterise the display, press the [P] key in operating mode for 1 second. The display then
changes to the menu level with the first menu item TYPE.
5. Setting the display
Menu level Parameterisation level
Selection of the input signal TYPE:
Default: sens
As measuring input variants 0/4-20 mA or 0-10 VDC signals are available as factory calibration
(without application of the sensor signal) and Sens as sensor calibration (with applied measuring
signal). With [P] the selection is confirmed and the display changes back to the menu level.
Setting the measuring range end value END:
Default: 1000
The final value is adjusted from the smallest to the largest digit with [▲] [▼]and confirmed
digit-selectively with [P]. A minus sign can only be parameterised on the highest value digit.
After the last digit the display changes back to the menu level. If Sens was selected as the input
variant, you can now choose between noca and cal.. With noca the previously set display value is
taken over, with cal the adjustment is made via the measuring section and the analog input value
is taken over.
Setting the measuring range start value offs:
Default: 0000
The initial value is adjusted from the smallest to the largest digit with [▲] [▼]and confirmed
digit-selectively with [P]. After the last digit the display switches back to the menu level. If Sens
was selected as the input variant, you can now choose between noca and cal.With noca the
previously set display value is taken over, with cal the adjustment is made via the measuring
section and the analog input value is taken over.
Setting the decimal point dot:
Default: 0
The decimal point of the display can be adjusted with [▲] [▼]. With [P] the selection is
confirmed and the display changes back to the menu level.

5. Setting the display
Menu-level Parameterization level
Setting the display time SEC:
Default: 01.0
The display time is set with [▲] [▼]. The jumps are in steps of 0.1 up to 1 second and in steps
of 1.0 up to 10.0. With [P] the selection is confirmed and the display changes to the menu level.
5.3. Programming interlock RUN
Activation/deactivation of the programming lock and completion of standard
parameterization run:
Default: uloc
Here, [▲] [▼] can be used to select between deactivated key lock Uloc (factory setting) and
activated key lock Loc. The selection is made with [P]. After this, the display confirms the
settings with "- - - -" and automatically switches to the operating mode. If Loc was selected, the
keyboard is locked. To enter the menu level again, [P] must be pressed for 3 seconds in the
operating mode. The now appearing CODE (factory setting 1 2 3 4)is entered with [▲] [▼]and [P]
and unlocks the keyboard. An incorrect entry is displayed with FAIL.
dann
Menu level Parameterization level
Rescaling the measurement input values, EndA:
With the help of this function the final value can be rescaled to e.g. 19.5 mA input signal without
applying the measuring signal. These parameters are not available when sensor calibration is
selected.
Rescaling the measurement input values, OFFA:
With the help of this function the initial value can be rescaled to e.g. 3.5 mA input signal without
applying the measuring signal. These parameters are not available when sensor calibration is
selected.
5.4. Extended parameterization
If the [▲] & [▼] keys are pressed for one second during standard parameterization, the display changes to the
extended parameterization mode. Operation is the same as in the standard parameterization.

7
5. Setting up the device
Menu level Parameterization level
Setting the tara/offset value, TArA:
Default: 0
The specified value is added to the linearized value. This is how the characteristic curve can be
shifted by the selected amount.
Zero point slowdown, ZErO:
Default: 0
With zero point calming, a value range around the zero point can be preselected at which the
display shows a zero. If, for example, a 10 should be set, the display would show a zero in a
value range from -10 to +10 and continue with -11 below and +11 above.
Assignment (deposit) of key functions, Tast:
Default: no
Here, either a min/max value query or a limit value correction can be stored on the direction
keys for the operating mode.
If the min/max memory is activated with EHER the measured min/max values are stored during
operation and can be retrieved via the direction keys [▲] [▼]. The values are lost when the
device is restarted. The values are lost when the device is restarted.
If the limit value correction LI.1 is selected, the values of the limit values can be changed during
operation without interfering with the operating sequence. With tara the display is tared to zero
and permanently stored as offset. The display acknowledges the correct taring with 0000 in the
display. If No is parameterized, the direction keys [▼] [▲] have no function in the operating
mode.
Flashing on display, FLAS:
Default: no
Here a display flashing can be added as an additional alarm function either to the first limit
value (selection: LI-1), to the second limit value (selection: LI-2)or to both limit values (selection:
LI-12). With No (factory setting) no flashing is assigned.
Limit value, LI-1:
Default: 0200
The limit value specifies the threshold above which the alarm reacts or is activated /
deactivated.

8
5. Setting up the device
Menu level Parameterization level
Hysteresis for limit value, HY-1:
Default: 0000
The hysteresis defines a difference to the limit value by which an alarm reacts delayed.
Function for limit value undercut/ limit value exceeded, FU-1:
Default: hi9h
The limit value violation is selected with Louu (for LOW = lower limit value) and that with HiGH (for
HIGH = upper limit value). Derived from "lower limit" = lower limit value and higher limit = upper
limit value. If, for example, limit value 1 is set to a switching threshold of 100 and assigned the
function high,the alarm is activated when the switching threshold is reached. If the limit value is
assigned to Low an alarm is triggered when the value falls below the switching threshold,
provided that the hysteresis is zero.
Limit values, LI-2:
Default: 0300
The limit value specifies the threshold above which the alarm reacts or is activated/deactivated.
Hysteresis for limit values, HY-2:
Default: 0000
The hysteresis defines a difference to the limit value by which an alarm reacts delayed.
Function for limit value undercut/ limit value exceeded, FU-2:
Default: hi9h
The limit value violation is selected with Louu (for LOW = lower limit value) and that with HiGH (for
HIGH = upper limit value) Derived from "lower limit" = lower limit value and higher limit = upper
limit value. If, for example, limit value 1 is set to a switching threshold of 100 and assigned the
function high ,the alarm is activated when the switching threshold is reached. If the limit value is
assigned to Low an alarm is triggered when the value falls below the switching threshold, as long
as the hysteresis is zero.

6. Reset to default values
Menu level parameterization level
Setting the code, CODE:
Default: 1234
With this setting it is possible to select an individual code (factory setting 1 2 3 4) for the
programming lock. For programming lock/unlock please proceed according to menu item run.
Number of additional supporting points, SPCt:
Default: 0
8 support points can be defined in addition to the start and end values in order to linearize non-
linear sensor values. Only the activated support point parameters are displayed.
Display value for supporting points, dIS1…dIS5:
Under this parameter the interpolation points are defined in terms of values. With sensor
calibration, as with end value/offset, you are asked at the end whether a calibration is to be
triggered.
Analogue values for supporting points, INP1…INP8:
The supporting points are always specified according to the selected input signal mA/V. Here
the desired analog values can be freely parameterized in ascending order.
6. Reset to default values
To set the device to a defined basic state, it is possible to perform a reset to the default values.
For this purpose, the following procedure shall be applied:
•Switch off the voltage supply of the device
•Press [P] key
•Switch on the power supply and press the [P] key until the display shows "- - - -"..
Reset loads the default values and uses them for further operation. This returns the device to the state it was
in on delivery.
ATTENTION!
•All application specific data is lost.

Limit value exceeded „High“
With the operating current, the
switching point S1-S2 is switched off
below the switching threshold and is
activated when the switching
threshold is reached.
limit value undercut „low“
During quiescent current, the
switching point S1-S2 is switched
below the switching threshold and is
switched off when the switching
threshold is reached.

8. Technical data

Please read the following safety instructions and the assembly chapter 2before installation and
keep it for future reference.
Intended use
The device is intended for the evaluation and display of sensor signals.
In the event of improper use or operation personal injury and/or damage to
property may occur.
Control of the device
The devices are checked before shipment and shipped in perfect condition. If any damage is
visible on the device, we recommend a close inspection of the transport packaging. In case of
damage, please inform the supplier immediately.
Installation
The device may only be installed by a specialist with appropriate qualifications, such as an
industrial electronics technician or a specialist with comparable training.
9. Safety instructions
Installation instructions
There must be no magnetic or electric fields in the immediate vicinity of the device, e.g. due to
transformers, two-way radios or electrostatic discharges. The fuse protection of the supply should
not exceed a value of 6A inert.
•Do not install inductive loads (relays, solenoid valves, etc.) close to the device and suppress them
using RC spark quenching combinations or free-wheeling diodes.
•Lay input and output lines spatially separated from each other and not parallel to each other.
Route outgoing and return lines side by side. If possible, use twisted-pair cables. This will give
you the most accurate measurement results.
•If high accuracy is required and the measuring signal is small, the sensor leads must be shielded
and twisted. As a general rule, these must not be laid in the immediate vicinity of consumer
supply lines. In the case of shielding, this should only be connected on one side to a suitable
equipotential bonding (usually knife-edge ground).
•The device is not suitable for installation in explosive areas.
•An electrical connection deviating from the connection diagram can lead to danger to persons
and destruction of the device.
•The clamp area of the devices is part of the service area. Hier sind elektrostatische Entladungen
zu vermeiden. Dangerous body currents can occur in the clamp area due to high voltages, which
is why increased caution is required.
•Galvanically isolated potentials within a system must be connected to a suitable point (usually
earth or system ground). This results in lower interference sensitivity to radiated energy and
avoids dangerous potentials that can build up on long lines or be caused by faulty wiring.
