Selection of measuring type/mode

1. by switching dipswitch no. 2 to position „ON“ 12 programming mode is accessed - LED „Lo“ lights up and LED „Hi“ signals the type of input by flashing (table 1)

2. change of input type, LED „Lo“ is green - by repeated pressing of button „Lo“ input types are accessed step by step and LED „Hi“ signals the type of input by flashing (table 1)

3. by pressing button „Hi“ our selection is confirmed and a next menu item can be accessed

4. setting the measuring range - LED „Lo“ is red and LED „Hi“

signals the type of measuring range (table 2) or for input type „DU“ it is the setting of minimum (if the slider is in a

Setting of Limits 1 (2)

1. after pressing button „Hi“ (for Limit 2 it is button „Lo“) red LED „L 1“ („L 2“) starts flashing and both LED “Lo” and “Hi” flash in cycles

2. set dipswitch no. 2 (for Limit L2 it is switch no. 1) to „ON“

, LED “Lo” an “Hi” flash in cycles

3. on the OMX 333 input set the sinal to the level required for the Limit to be actuated

4. select your setting by pressing the „Hi“ button and switch the dipswitch no. 2 to „OFF“

Setting of Analogue/Data output

1. by switching the dipswitch no. 1 to „ON“ of output by flashing (table 4) or the rate of analogue output (table 5)

2. by repeated pressing of button „Lo“ the types of analogue output are accessed (rychlosti) and LED „Lo“ signals the the type of output (tab. 4) or the rate of data output (tab. 5)

3. by pressing „Hi“ the selected setting is confirmed and a next menu item can be accessed (only for further setting of data output)

4. by repeated pressing of „Lo“ button instrument‘s address can be set ang LED „Lo“ signals by flashing the address of OMX 333 (table 5) (this procedure only applies to setting of data output)

5. our setting is confirmed by pressing „Hi“ button and progarmming mode is exited by switching dipswitch no. to „OFF“

programming mode is accessed - LED „Hi“ lights up and LED „Lo“ signals the type

Changing analogue output (AO) range

1. OMX 333 AO is set by manufacturer. This procedure is for experienced users

2. by switching dipswitches no. 1 and no 2 to „ON“

3. to input terminals of OMX 333 connect signal of requested level which equals to minimum range of AO (for example 4 mA) and by pressing „Lo“ button this value is recorded, LED „Lo“ ﬂ ashes twice the normal rate

4. to input terminals of OMX 333 connect signal of requested level which equals to maximum range of AO (for example 20 mA) and by pressing „Hi“ button this value is recorded, LED „Hi“ ﬂ ashes t wice the normal rate

5. by switching dipswitches no. 1 and 2 to „OF F“

programming mode is accessed - LED „Lo“ and „Hi“ ﬂ ash alternatively

programming mode is exitted

Restoration of manufacturer‘s /user settings

1. this is a good way how to return to the original manufacturer’s setting especially when making a mistake during the set up process

2. by pressing buttons “Lo” and Hi” simultaneously for approx 2 s LEDs „Lo“ and „Hi“

3. by switching dipswitches no. 1 and 2 to „ON“

the rate of flashing increases

4. by pressing button „Hi“ restoration of manufacturer‘s setting is executed (linearisation table, if it had been entered, is deleted), by pressing button „Lo“ restoration of user settings including those which had been set via OM Link SW is executed, (linearisation table remains)

5. by switching dipswitches no. 1 and 2 to „OF F“

this mode is exitted

start flashing alternatively

Instrument‘s power supply leads should not be in vicinity of low level input signals. Contactors, medium and high power electrical motors must not be used in vicinity of the instrument. Input signal leads (measured value) need to be separated from all high power leads and devices. Instruments are tested in accordance with standards for industrial use, however we strongly advise you to adhere to the above mentioned precaution measures.
