3.2 Intended use
The instrument has been designed and built solely for the intended use described here, and may only be used
accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
Intended use
The PSD-4 pressure switch is used for the switching of circuits as a function of the measured pressure. In addition, the
pressure value can be output to appropriate read-out units as a standardised analogue signal. The switching conditions
can be programmed directly at the pressure switch (switch and reset points, ...). Via the different display elements,
switching statuses and pressure values can be read.
This is a class B instrument for emissions and is intended for use in industrial environments. In other environments,
e.g. residential or commercial installations, it can intefere with other equipment under certain conditions. In such
circumstances the operator is expected to take the appropriate measures.
