1. Product Description

2. Starting operations

Electrical connections plug 1 (standard) and power supply

Intended Applications

- The dual pressure switch is a device to monitor system pressure
and has up to two switching outputs and one analog output.

- The instruments must only be installed in systems where the
maximum pressure Pmax or the maximum temperature Tmax is
not exceeded (according to the values on the type label).

- Attention: This device is not designed to be used as the only
safety relevant element in pressurized systems according PED
97/23/EC.

Only assemble or disassemble the device when depressurized!

Connecting the switch

- Mount the pressure switch from bottom to the fitting with a wrench hex 19 (1/4“) resp. hex 22
with 45 Nm torque.

- Electrical connection depends on the type of pressure switch (see type label) according to the
chart below (connection chart plug 2 for interface see page 4).

- When display is adjusted (rotable version only) the unit has to be fixed at the front side with
an allen screw and and allen key 1,5 mm (torque = 3 Nm).

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).
