OMX 333UNI
SETTING
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
- by repeated pressing of button „Lo“ measuring ranges are accessed step by step
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
static position, then by pressing button „Lo“)

5. by pressing button „Hi“ our selection is confirmed and a next menu item can be accessed (if it exists for the given type), otherwise
there is return to type
6. setting of connection (only for type DU, OHM, Pt, Ni, Cu, T/C) - LED „Lo“ does not light up - by repeated pressing of button „Lo“
types of connection are accessed and LED „Hi“ signals the type of connection (table 3) or for type „DU“ setting the maximum
(if the slider is in a static position, then by pressing button „Hi“)
7. by pressing „Hi“ selected setting is confirmed and dipswitch no. 2 can be switched to „OFF“
12
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“
12
, 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“
12
Setting of Analogue/Data output
1. by switching the dipswitch no. 1 to „ON“
12
programming mode is accessed - LED „Hi“ lights up and LED „Lo“ signals the type
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“
12
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“
12
programming mode is accessed - LED „Lo“ and „Hi“ fl ash alternatively
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 twice the normal rate
5. by switching dipswitches no. 1 and 2 to „OFF“
12
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“
start flashing alternatively
3. by switching dipswitches no. 1 and 2 to „ON“
12
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 „OFF“
12
this mode is exitted
