Pressure Control
Setting of the desired value (Set-Point)
The supplied pressure transmitter has a working range dened by the specications of each
generator. Normal ranges are 0 - 3, or 0 – 10 bar. It is important that the working range of the transmitter
matches that programmed in the control unit.
Set point values exceeding the maximum limit of the transmitter range are not accepted by the system.
The maximum acceptable values are stored in the area of conguration parameters. They can be modied
only by authorized personnel via a password.
The maximum limit of alarm (pressure switch) has to be in any case lower than the discharge pressure of
the safety valve supplied with the generator. This pressure value is indicated on the tag of the safety valve.
