Operation
The pressure switch should be installed and operated only by authorized persons. After being switched on,
the PSW2000 runs through a self-text. 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 menus (see below “List of functions“).
If the dialog is not continued within two minutes the device automatically returns to the measuring mode.
When the software 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
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 holding the “M“ -key pressed for five seconds.
If the key lock has been activated, the values can be shown, but no changes made. ( ““appears in the
display when an attempt is made to change values). The key lock is activated by pressing the ““and ““
keys simultaneously for at least five seconds. Press again to deactivate the key lock again.
DESINA conformity:
When the switch operates in systems according to DESINA standard, switching point SP2 has to be
programmed as monitoring function: Enter the value (error output) in programming step and the
value (normally closed function) in programming step .
In case of error identification (see menu) a diagnosis signal is automatically actuated on the alarm dis-
play on the front panel and on switching point SP2 (pin 2).
