Abstract

All the high voltage supply circuits (E1,..E4) for the atomisers (Z) are connected to a common earthing switch (ES). It contains individual contacts (b1,..b4) for each circuit, an earth contact (c), and a moving contact section (SG). All are contained in a common housing. The earthing switch is closed automatically by remote control (D,67) if one of the safety switches or sensors (M) is operated, for example, if one of the doors (T) to the spraying enclosure is opened when work is in progress. The earthing switch is typically sealed and filled with an inert or insulating gas. The switch mechanism is operated hydraulically or pneumatically via a piston (67). The safety circuits are typically electrical. The control unit (D) can also give an indication (A) at the atomisers to show that the HV circuit is earthed.
