Barksdale UDS7-BX - Manual (Page 3)

5. Operation:
The pressure switch should be installed and operated only by authorized persons.
After connecting and energizing, the UDS7-BX runs through a self-test. The device is menu operated
and configured with three keys on the front. See sections 3 and 4 of these instructions.
With the “M“ key (= mode) you change between the dialog values and the adjusted/actual values.
With the keys “▲“ = up and “▼ “= down you change between the dialog values in the menu or
change the values/functions in the menus
If the dialog is not continued within two minutes the device automatically returns to the measuring
mode. When the programming lock is entered, “LOH“ appears in the display when an attempt
is made to change values.
Programming:
The programming menu is activated as described in section 3 of these instructions. The dialog
items are selected with the “▲“ and “▼“ keys. If the mode key is pressed again the corresponding
value for the dialog item is
shown and can be altered with the “▲“ and “▼“ keys. If the dialog with
the unit is not continued within two minutes the device automatically returns to the measuring mode
without accepting the new values.
To terminate programming more quickly, you can switch back to the measuring mode (primary
menu) from any item in the menu by pressing and holding the M-key for five seconds.
If the programming lock has been activated, the values can be shown, but no changes made,

** Note: When changing units from psi to bar or bar to psi, the switching point values must be changed
accordingly. For pressure ranges greater than 1000 psi, only the selections of
“PSH” and “bar” are
available. If other units are selected the measurement will default to „bar‟ and switch point settings will
require re-setting.
