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)
- 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 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
266 000 values may be stored in the instrument memory. Data transmis sion into PC via serial interface RS232/485 and OM Link.
INSTRUCTIONS FOR USE OM 502 | 5
3. 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.

The lowest recording rate possible is once a day, the highest is every second. Under
exceptional circumstances it is possible to set the rate to 8 times per second by entering
the recording period as 00:00:00. However, this mode is not recommended due to the
memory overload. Recordings are realised in a timeframe of one day and are repeated
periodically every following day. Recordings can take place either inside or outside of
selected time intervals. The duration of re-writing can be determined by the number of
channels recorded as well as by the recording rate.

Setting logging data into

data logging prior to initiation of trigger imputse
- initialization is on ext. input or button
- setting in range 1…100 %
- when setting 100 %, datalogging works in the

1. Memory initialization
- clear memory (ext.input, button)
FAST
The memory operates on the basis of memory oscilloscope. Select an area of 0…100%
of the memory capacity (100% represents 8 192 individual recordings for a single
channel measurement). This area is filled cyclically up to the point when the recording
starts (activated by the front panel button or by an external input). When the remaining
memory capacity fills up the recording stops. A new recording is possible after the
deletion of the latest recording. It is possible to abort a recording before its completion
by reading out the data.
- LED “M” flashes, after reading TRIGGER (%)
memory is permanently shining. In ROLL flashes
constantly.
2. Triggering
- external input, button
- after the memory LED is full “M” turns off
- in the ROLL mode the trigger ends datalogging
and LED turns off
3 . Termination
- ext. input, button or reading data via RS

8. 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:
DIN MessBus:
8 bit, no parity, one stop bit
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 www.orbit.merret.cz or SW OM Link.

TABLE OF SIGNS 10.
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
