Use
If an emergency situation should arise during the
filling of the cylinders, press the “OFF” button
located on the control board (Fig. 79).
The machine is provided with an emergency system that automatically blocks it when:
1) the pressure set on the pressure switch is reached;
2) there is a temporary cut in the power supply;
3) the heat release of the electric motor trips due to an overload.
After an emergency stop and before proceeding with a subsequent operation, it is necessary to check
that the cause of the emergency has been eliminated.
