Omega Engineering PSW1000 - Manual (Page 6)

Operation:
The pressure switch should be installed and operated only by authorized persons.
After being switched on the PSW1000 runs through a self-test. The device is menu operated and
configured with three keys on the front.
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 menues (see below: “List of functions“).
If the dialog is not continued within two minutes the device automatically returns to the measuring
mode. When the programming lock is entered, “LOCK“ appears in the display when an attempt is made
to change values.
Programming:
The setting menu is activated with the mode key. 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 auto-matically 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 holding the M-key pressed for five seconds.
If the programming lock has been activated, the values can be shown, but no changes made, i.e. when
Level 0 is active (“LOCK“ appears in the display when an attempt is made to change values).
