4|INSTRUCTIONS FOR USE OMB 450UNI
2.1 DESCRIPTION
The OMB 451/452 model series are programmable, three-color panel bargraphs with auxiliary display and adjustable
LCD scale. The instruments are designed as dimensional replacement of the ZEPAKOMP instruments. Available are types
UNI, PWR and UQC.
Type OM 402UNI is a multifunction instrument with the option of configuration for 8 various input options, easily configurable
in the instrumentmenu. By further options of input modules it is feasible to measure larger ranges of DC voltage and current
or increase the number of inputs up to 4 (applies for PM).
The instrument is based on an 8-bit microcontroller with a multichannel 24-bit sigma-delta converter, which secures high
accuracy, stability and easy operation of the instrument.
The OMB 451/452 is a multifunction instrument available in following types and ranges

INSTRUMENT DESCRIPTION2

INSTRUCTIONS FOR USE OMB 450UNI |5
Peak value: the display shows only max. or min. value
Mat. operations: polynome, 1/x, logarithm, exponential, power, root, sin x
EXTERNAL CONTROL
Lock: control keys blocking
Hold: display/instrument blocking
Tare: tare activation/resetting tare to zero
Resetting MM: resetting min/max value
Memory: data storage into instrument memory
2.2 OPERATION
The instrument is set and controlled by five control keys located on the front panel. All programmable settings of the instrument
are performed in three adjusting modes:
LIGHT Simple programming menu
- contains solely items necessary for instrument setting and is protected by optional number code
PROFI Complete programming menu
- contains complete instrument menu and is protected by optional number code
USER User programming menu
- may contain arbitrary items selected from the programming menu (LIGHT/PROFI), which determine
the right (see or change)
- access without password
All programmable parameters are stored in the EEPROM memory (they hold even after the instrument is switched off).
Complete instrument operation and setting may be performed via OM Link communication interface,
which is a standard equipment of all instruments.
The operation program is freely accessible (www.orbit.merret.cz) and the only requirement is the
purchase of OML cable to connect the instrument to PC. It is manufactured in version RS 232 andUSB and is compatible
with all ORBIT MERRET instruments. Another option for connection is with the aid of data output RS 232 or RS 485 (without
the need of the OML cable).
The program OM LINK in „Basic“ version will enable you to connect one instrument with the option of visualization and
archiving in PC. The OM Link „Standard“ version has no limitation of the number of instruments connected.
2.3 OPTIONS
Excitation is suitable for supplying power to sensors and transmitters. It has a galvanic separation.
Comparators are assigned to monitor one, two, three or four limit values with relay output. The user may select limits regime:
LIMIT/DOSING/FROM-TO. The limits have adjustable hysteresis within the full range of the display as well as selectable
delay of the switch-on. Reaching the preset limits is signalled by LED and simultaneously by the switch-on of the relevant relay.
Data outputs are for their rate and accuracy suitable for transmission of the measured data for further projection or directly
into the control systems. We offer an isolated RS232 and RS485 with the ASCII or DIN MessBus protocol.
Analog outputs will find their place in applications where further evaluating or processing of measured data is required in
external devices. We offer universal analog output with the option of selection of the type of output - voltage/current. The
value of analog output corresponds with the displayed data and its type and range are selectable in Menu.
Measured data record is an internal time control of data collection. It is suitable where it is necessary to register measured
values. Two modes may be used. FAST is designed for fast storage (40 records/s) of all measured values up to 8000
records. Second mode is RTC, where data record is governed by Real Time with data storage in a selected time segment
and cycle. Up to 250 000 values may be stored in the instrument memory. Data transmission into PC via serial interface
RS232/485 andOM Link.
2INSTRUMENT DESCRIPTION

6|INSTRUCTIONS FOR USE OMB 450UNI
The instrument supply leads should not be in proximity of the incoming low-potential signals. Contactors, motors with larger
input power should not be in proximity of the instrument. The leads into the instrument input (measured quantity) should be
in sufficient distance from all power leads andappliances. Provided this cannot be secured it is necessary to use shielded
leads with connection to ground (bracket E).
The instruments are tested in compliance with standards for use in industrial area, yet we recommend to abide by the above
mentioned principles.

Maximum of 250 mA may be connected to “INPUT - I” (bracket no. 23) , i.e. 10-times range overload.
Mind the correct connection/mistaking of current - voltage input.
Destruction of measuring resistance in current input (15R) may occur.
!
!
Excitation has the minus pole common with the
input - the bracket no. 22 - GND and you may set its
value by trimmer above the bracket no. 16

to connect the instrument to PC. It is manufactured in version RS 232 and USB and is compatible with all ORBIT MERRET
instruments.
Another option for connection is with the aid of data output RS 232 or RS 485 (without the need of the OML cable).
