INSTRUCTIONS FOR USE OMX 100

2. INSTRUMENT DESCRIPTION

DESCRIPTION

The OMX 100 model series are programmable transmitters to DIN rail manufactured in the following types:

OMX 100DC DC voltmeter/ammeter OMX 100PWR AC voltmeter/ammeter, wattmetr OMX 100PM Process monitor OMX 100RTD Thermometer for Pt 100/500/1 000, Ni 1 000 OMX 100T/C Thermometer for thermocouples OMX 100DU Display instrument for linear potentiometers OMX 100OHM Ohmmeter OMX 100F Frequency meter

The instruments are based on an 8-bit microcontroller with A/D converter, that secures high accuracy, stability and easy operation of the instrument.

* only for type DC, PM, DU

2. INSTRUMENT DESCRIPTION

OPERATION

The transmitter is set by two control keys on the front panel or via data line RS 232/485. A standard equipment is the OM Link interface, through which it is possible to modify and store all settings. The

OM Link program is freely procurable, to be downloaded from the web site. For the connection an OM Link cable is necessary. All programmable parameters are stored in the EEPROM memory (they hold even after the instrument is switched off).

EXTENSION

Excitation is suitable for feeding sensors and converters. It has a galvanic isolation of 12…24 VDC. Comparators are assigned to control two limit values with relay output. The limits have adjustbale hysteresis 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 RS 232 and RS 485 with the ASCII protocol.

Real time is an internal time control of data collection. It is suitable everywhere where it is neccessary to register measured values in a given time segment. Up to 65 000 values may be stored in the instrument‘s memory. Data transmission into PC via serial interface RS232/485

FIRMWARE www.orbit.merret.cz/update

With respect to the continuous development and innovation of our products it is now possible to download the most recent program version for every instrument directly from the web pages.

After connecting the instrument to PC and running the program the upgrade is performed automatically . Number of the current program version in your instrument can be found in „Configuration menu - service - identifi-

cation“

INSTRUCTIONS FOR USE OMX 100

3. CONNECTION

The lead for feeding the instrument should not be in the proximity of the incoming low-potential signals. Contactors, motors with larger input power and other efficient elements should not be in the proximity of the instru-

ment. The lead into the input of the instrument (the 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. The instruments are tested in compliance with standards for use in industrial area, yet we recommend to abide by

the above mentioned principles.

Grounding on terminal „E“ has to be connected at all times.

Feeding of an open collector (OC) for frequency output max. 40 V, (internal

resistance 5k6)

Relay parameters listed in Technical data apply for resistance

load. Upon connection of induction load we recommend ﬁtting the leads to relay 1 A with a fuse for protection of maximum load.

In RTD and OHM inputs it is necessar y in 2 or 3-wire connec-

tion to link the unconnected inputs to terminal board.
