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:
ACT
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:
S 1
"PSI" – Pounds per square inch (psi)
"PSH" – PSI/10
"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.

- Page 2 Selecting the Units of measure for the above displayed value: This menu option allows the user to turn on/off the display of the unit of measure. Selecting “on” will set the unit to display the unit of measure every 30 s. Selecting “off” will turn off the display. ▲...
- Page 3 enter the menu for setting the switch-on delay. Set the desired delay between 0.0 seconds and 9.9 seconds using the arrows to change digits, and the “M” to move from one digit to the next. Once done, the “M” will take the user back to the menu with the “dS1”.
- Page 4 Window mode programming: The above was a detailed explanation of the standard mode setting. The UDS7-BX unit is also capable of window mode programming. Window mode allows the user to monitor either within a range or outside of a range of pressure. For example, the user can have the switch ON between any two pressures, or outside of any two pressures.
- Page 5 Using the instructions above, set the following parameters: “SP1” = uln “on1” = 500 “OF1” = 400 “lu1” = HFS Note that reversing the on1 and OF1 will reverse the state of the switch to OFF between the set points and ON outside of them. For simplicity of understanding, it is suggested that the high limit be used for “on1”...
