If hydraulic actuators are equipped with position transmitters meeting the requirements outlined in section
6.6, there is no need for calibration. In cases where the 4-20 mA signals do not cover the whole area, the
transmitters need to be recalibrated. Otherwise the position indication and valve control from the HMI will
not work appropriately.

6.7. Configuration

6.7.1 Safety valve

The purpose of the safety valve is to protect the internal components from too high pressure. The valve is
pre-set at the factory to 150 bar and secured so that the pressure limit cannot be accidentally changed
during installation or use. The safety valve can be adjusted between 0-250 bar. Safety valve adjustment
should not be made without consulting the valve, actuator, and control cabinet suppliers.
