Function and features
The pressure monitor detects the system pressure and switches the two comple-
mentary outputs OUT1 (pin 4) / OUT2 (pin 2):
• In case of increasing pressure OUT1 closes / OUT2 opens when the set Set
value is reached.
• In case of decreasing pressure OUT1 opens / OUT2 closes when the set Reset
value is reached.

Avoid static and dynamic overpressure exceeding the given over-load
pressure.
Even if the bursting pressure is exceeded only for a short time the unit can
be destroyed (danger of injuries)!

Installation
Before mounting and removing the sensor, make sure that no pressure is
applied to the system.
Mount the pressure sensor on a suitable process connection (see type label “Port
Size”). Tightening torque 25 Nm.
Electrical connection
The unit must only be connected by an electrician.
The national and international regulations for the installation of electrical
equipment must be observed.
Voltage supply to EN50178, SELV, PELV.
The device shall be supplied from an isolating source and protected by
an overcurrent device in accordance with UL 248 such that the limited
voltage/current circuit requirements in accordance with UL 508 are met.
