Orbit Merret OMX 333UNI Quick Start Manual

OMX 333UNI
SETTING
Selection of measuring type/mode
1. by switching dipswitch no. 2 to position „ON"
type of input by flashing (table 1)
2. change of input type, LED „Lo" is green
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
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
types of connection are accessed and LED „Hi"
(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"
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
2. set dipswitch no. 2 (for Limit L2 it is switch no. 1) to „ON"
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"
1 2
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"
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"
(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"
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"
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"
5. by switching dipswitches no. 1 and 2 to „OFF"
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"
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"
1 2 programming mode is accessed - LED „Lo"
- by repeated pressing of button „Lo" input types are accessed step by step and LED „Hi"
- by repeated pressing of button „Lo" measuring ranges are accessed step by step
