. DEVICE DESCRIPTION
2.1 Description
The OMX series are DIN rail mountable programmable transducers designed for maximum convenience
and user convenience. Available versions are UNI (universal), DC (DC current andvoltage), PWR (power), UQC
universal quadrature counter and T (load cell).
Type OMX UNI is a multifunctional dual-input device with the possibility of configuration for different
input variants easily configurable in the device menu.
The OMX is based on a single-chip microcontrollerwith -bit A / D converter, which provides very good
accuracy, stability and easy operation.
VERSIONS AND MEASURING RANGES
UNI or individual isolated inputs
DC ±/±/ mV; ±/±/± V; ±/± mA
PM ±/± mA/… mA; ±/±/± V
OHM …/// /…,/// k

Cu Cu /
Ni Ni /
T/C J/K/T/E/B/S/R/N/L
DU Linear potentiometer (min. )
CONFIGURABLE PROJECTION
To be selected: input type and measuring range
Configuration: standard - projection setting for both endpoints of input range
teach-in - projected endpoints of input range can be assigned to any two values of
(unknown) input signal.
manual - projection setting for both set endpoints of input range
Projection: -…
ANALOGUE OUTPUT
Type: isolated, user configurable, bit resolution, rate < ms
Quantity: …
Ranges: …// V, ± V, … mA, /… mA
COMPENSATION
Leads (RTD, OHM): -wire compensation can be realised in the device menu
Probe (RTD): internal connection (resistance of leads inside the temperature probe)
Cold junction (T/C): manual or automatic. Selection of thermocouples as well as the cold junction
compensation can be made in the menu. This could be set by user, or be automatic
(temperature of screw terminals)
LINEARIZATION
Linearization:* linear interpolation in points (possible only with Link SW)
DIGITAL FILTERS
Floating average: from … measurements
Exponent. average: from … measurements
Arithmetic average: from … measurements
Rounding: setting the rounding step for the display
* only for input types DC, PM, DU
USER MANUAL OMX 103UNI | 5
.DEVICE DESCRIPTION
MATHEMATIC FUNCTIONS
Min/Max. vale: preserves min./max. values reached during a measurement
Tare: is used to reset the displayto zero even when the input signal does not correspond to zero
Peak value: display projects only max. or min. value
Math operations: polynomial, /x, logarithmic, exponential, power, root, sin x
and mathematic operations between inputs - sum, multiple and ratio
EXTERNAL CONTROLS
Lock: front panel keys are blocked
Hold: freezing the display/instrument
Tare: applying tare/resetting tare
Resetting Min/Max: resetting of Min/Max value
■Controls
Device is controlled by two keys located on the front panel or by OM Link SW. Settings can be realised in three
levels.
LIGHT Simplified menu
- contains only the most essential menu items that are necessary for setting up the device.
It can be password protected.
PROFI Complete menu
- contains all menu items and it can be password protected
USER User define menu
-somemenuitem(LIGHT/PROFI) canbe includedintothismenu.Accessrightstoeachmenu
may be assigned (to view only, or to edit)
- no password access
All configuralbe parameters are stored in EEPROM memory (remain stored even after power off).
All settings may be realised via PC' USB interface using our free to download SW called
OM Link.
OM Link „Basic“ provides for connection of ORBIT MERRET device to PC. OM Link also makes it possible
for the measured values to be visualised and archived in the PC. „OM Link Standard“ does exactly the sam
without the number of OM devices being limited.
■Options
Comparators (in the form of relays oropen collectors), are designed for monitoring one to six limitvalues. The
user can select the limit mode: LIMIT / DOSE / FROM-TO. Limits have adjustable hysteresis in the full range
of the displayed value and an optional switch-on delay in the range of … . s. Reaching the set limits is
signalled by LEDs and at the same time by actuating the relevant relay.
Data outputs Due to their speed and accuracy, data outputs are suitable for transferring measured data to
other displays, or directly to control systems. We offer isolated RS and RS data outputs with ASCII,
DIN MessBus and MODBUS RTU protocol, Profibus DP communication card or Ethernet.

. DEVICE CONNECTION
3.1 Connection
Power supply leads should not be in the vicinity of the low voltage input signals.
Contactors, high power motors and other power elements should not be in the vicinity of this device.
Input signal leads (measured value) should be sufficiently far away from all power lines and appliances. If this
cannot be ensured, a grounded shielded cable (terminal E) must be used.
This device has successfully passed tests according to the industry standards, however we still recommend
that you observe the above guidelines.

■Setting via USB interface
Use of OM Link software is recommended for more convenient setting of the converter. Use a USB to micro
USB cable to connect to your computer.
The OM Link SW can be downloaded free of charge at www.merret.cz/produkty/software/om-link
There is a microUSB connector located under the front cover. To access the connector, the cover needs to
be removed.
USB cable connection
Gently pry open the front cover in the areas indicated in the picture and
remove it.
Connect to PC using a USB to microUSB cable and
launch OM Link SW. Make sure input signal is not
connected!
