SAFETY INSTRUCTIONS
Please read carefully the enclosed safety instructions and observe them!
Installation, all operational interventions, maintenance and service must be performed by a qualified personnel
and in accordance with the attached information and safety regulations. The manufacturer is not liable for
damage caused by improper installation, configuration, maintenance, and service.
The recorder must be installed according to the respective application. Incorrect installation can cause a
malfunction, which can result in damage or accident.
The recorder uses dangerous voltages that can cause a fatal accident. Before you start solving problems
(e.g. in TIMEe of failure or disassembly), the device must be disconnected from the power supply. For safety
information the EN - + A standard must be observed.
When removing or inserting a card, observe the safety instructions and follow the recommended procedure.
During any intervention the recorder must be disconnected from the power supply.
Do not attempt to repair or modify the device. A defective recorder must be sent for repair to the manufacturer.
These devices should be safeguarded by isolated or common fuses (breakers)!
The recorder is not designed for installation in potentially explosive surroundings (Ex). Use it only outside
potentially explosive surroundings

. INSTRUMENT DESCRIPTION
2.1 DESCRIPTION
The OMD  model series are / digit large panel programmable displays designed for maximum efficiency and user comfort
while maintaining their favourable price. It comes either with a -colour LED display (red/green/orange) or with High Brightness
LEDs (red or green with brightness of   mcd).
Type OMD UNI is a multifunction instrument with the option of configuration for  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  (applies for PM).
The instrument is based on an -bit microcontroller with a multichannel -bit sigma-delta converter, which secures high accuracy,
stability and easy operation of the instrument.
THE OMD  IS A MULTIFUNCTION INSTRUMENT AVAILABLE IN FOLLOWING TYPES AND RANGES

2.2 OPERATION
The instrument is set and controlled by IR Remote control. 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)
- acces 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.eu) and the only requirement is the purchase of OML cable to connect
the instrument to PC. It is manufactured in version RS  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 in the range of ..., s. 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 RS and RS 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.

. INSTRUMENT CONECTION
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. 8) , 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.
