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).
