UDS7-BX Supplemental Programming Instructions
The entire programming of the UDS7-BX Electronic Pressure Switch can be done using three buttons on the face of the unit.
The M is Menu. The Up and Down arrows are used to scroll through the possible menu selections. This manual guides the
user in programming this unit.
Connect the unit to power before beginning.
If the unit is locked, “LOH” will appear when trying to change any settings. Press and hold both arrow keys at the same time
for approximately 5 seconds. This will unlock unit and allow for settings to be changed. Repeat to toggle back into a locked
state.
Read Actual Measured Value:
The ACT menu is available to read the actual value regardless of what parameter has been selected above. From the Menu,
scroll down to ACT, and press M. The actual pressure will be displayed. To exit this mode, press M again.
Selecting the Units of measure for the above displayed value:
There are five choices of units:
“PSI” – Pounds per square inch (psi)
“PSH” – PSI/10
(Use for high pressures since the display has a max of 3 characters)
“bar” – BAR
“nbar” – Millibar
“hPo” – Hectopascal
“nPo” – Millipascal
To select the units, Press “M” to access menu. Using the down arrow, scroll to “S 1”. Press “M” to select programming units.
Using arrows, scroll thru selections above. When you see the selection you want, press “M”. For example, to display the
value in PSI, scroll to “PSI” and press “M”. To exit programming, use the arrows to scroll back up to “MENU” and press
“M”.
NOTE: Changing the units of measure does not change the set point values. Therefore, the user must convert each set
point and reprogram the UDS7-BX when units of measure are changed.
