The discharging power pack EN 9 Sine supplies energy to HAUG ionizing units. A functional monitoring facility reports impermissible operating states in the ionizing system such as short circuit and spark formation or thermal overload. The EN 9 Sine can be pulsed and supplies a monitoring signal of the output high voltage. FUNCTIONAL PRINCIPLE The EN 9 Sine provides a high voltage of 7–8 kV AC and supplies HAUG ionizing units with a connected length of 18 m max. (incl. HV cable). The signalling socket K1 supplies a linear monitoring signal of the output high voltage for reporting and control purposes. At an output high voltage of 7 kV AC, for example, the monitoring signal has a voltage level of 7 VDC. In addition, the output high voltage of the EN 9 Sine can be pulsed via signalling socket K1. This means that the ionization process of the connected ionizing units can be switched on and off from a control desk or machine control unit. This allows the ionizing system to be operated very efficiently with regard to the energy input. The function monitoring facility of the EN 9 Sine permanently monitors the output high voltage in the components of the ionization system – from the discharging power pack via the high voltage lines through to the connected ionizing units. In the event of a short circuit or spark formation in the ionizing system, e.g. due to faulty insulation, the EN 9 Sine will switch off the output high voltage and report the fault via a signalling lamp. The monitoring signal of the output high voltage drops to 0 V.
