1. Short description
1. Short description
The switch panel meter UDA 50...-U... is a 4-digit digital display for measuring various measuring
signals such as voltage/current, temperature and frequency. The configuration is done via 3 front
keys or by means of an optional PC software PM-TOOL. An integrated programming lock
prevents unwanted changes to parameters and can be unlocked again via an individual code.
With the 2 integrated semiconductor switching points, limit values can be monitored and reported
to a higher-level control room. The electrical connection is made at the rear via plug-in clamps.
Selectable functions such as min/max value query, tare function, averaging, direct limit value
adjustment in operating mode and additional measuring support points for linearization of the
measuring input meet the requirements of measurement and control technology.

4. Functional description and operation
Key symbol Function in operating mode Function during parameterization
Program key [P] The program key [P] is used to
switch to parameterization. Change to a lower parameter level or to the stored value.
Minus key [▼]
The minus key [▼] can be used
to call up the min value or change
a lower limit value, depending on
the key function set.
Switching between parameters and
changing parameters in the value
level.
Plus key [▲]
The plus key [▲] can be used to
call up the max value or change a
lower limit value, depending on
the key function set.
Switching between parameters and
changing parameters in the value
level.
4. Functional description and operation
4.1. Operating and display elements
The display has 3 keys with which you can parameterize the device and call up stored functions
during operation. Functions that can be adjusted or changed are always signaled with a flashing
of the display. The settings made in the parameter level are always confirmed with [P] and thus
saved. However, the display also automatically saves all adjustments and switches to operating
mode if there are no further key operations within 10 seconds.
A switched on relay or an activated switching point is visually signaled by a lighting of the
respective switching point LED next to the 7-segment display.
A display overflow/underflow is indicated by 4 bars "- - - -".
Numerical values are adjusted from the smallest to the largest digit with [▲] [▼]and confirmed
digit-selectively with [P]. A minus sign can only be parameterized on the most significant digit.
After the last digit, the display switches back to the menu level.
Example: Setting of device parameters, e.g. selection of input signal
Parameter Selection option
Example: Setting numerical values, e.g. measuring range end value

4. Functional description and operation / 5. Setting the display
4.2. Programming via configuration software PM-TOOL:
Part including the software on CD, is a USB cable with device adapter. The connection is
established via a 4-pin micromatch connector on the back of the device and to the PC side with a
USB connector.
System requirements: PC with USB interface
Software: Windows XP, Windows VISTA
With this tool the device configuration can be generated, omitted and saved on the PC. Through
the easy-to-use program interface, the parameters can be changed, whereby the mode of
operation and the possible selection options are specified by the program.
ATTENTION!
When setting parameters with a measuring signal connected, make sure that the measuring
signal does not have a ground reference to the programming plug.
The programming adapter is not galvanically isolated and is directly connected to 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. Switch on
After completing the installation, you can put the device into operation by applying the supply
voltage. Before doing so, check all electrical connections once again to ensure that they are
correctly connected.
Start sequence
During the switch-on procedure, the segment test (8 8 8 8), the message of the software type and
afterwards for the same time the software version are displayed for 1 second. The start sequence
is followed by the change to the operating or display mode.
