Operationn
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)
- 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.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 in the range of 0...99,9 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 RS232 and RS485 with the ASCII, MESSBUS, MODBUS - RTU or PROFIBUS
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 (100 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 transmis sion into PC via serial interface
RS232/485 and OM Link.

INSTRUMENT CONNECTION
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.

INSTRUMENT SETTING

Setting
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)
- 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.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).

DATA PROTOCOL
The instruments communicate via serial line RS232 or RS485. For communication they use the ASCII protocol. Communication runs in the following format:
ASCII:
8 bit, no parity, one stop bit
DIN MessBus: 7 bit, even parity, one stop bit
The transfer rate is adjustable in the instrument menu. The instrument address is set in the instrument menu in the range of
0 ÷ 31. The manufacture setting always presets the ASCII protocol, rate of 9600 Baud, address 00. The type of line used
- RS232 / RS485 - is determined by an output board automatically identified by the instrument.
The commands are described in specifications you can find at na www.orbit.merret.cz/rs or in the OM Link program.

The instrument allows to add two descriptive characters to the classic numeric formats (at the expense of the number of displayed places). The setting is performed by means of a shifted ASCII code. Upon modification the first two places display the
entered characters and the last two places the code of the relevant symbol from 0 to 95. Numeric value of given character
equals the sum of the numbers on both axes of the table.
Description is cancelled by entering characters with code 00
