4. Operation
4.1 Startup
Before starting up the power supply the user must make sure that the
power supply and the bars have been installed and assembled
correctly. The supply voltage can then be switched on.
Use the toggle switch (4, Fig. 1) to switch on the power supply. In the ON
position the switch lights up green. High voltage is now supplied to the
discharging bars.
The output voltage is now a constant 5 kV AC.
If the fuse is defective, the switch will not light up.
4.2 Function and pollution monitoring (optional)
In general, proper operation is indicated by the illuminated switch in all
units.
The optional function and pollution monitoring analyses the high voltage
signal at the output.
• High voltage is indicated by a green LED in the front panel (active). A
floating change over contact is available for transmitting this signal.
• If a defect or fault is detected (e.g. sparking, dirt or arcing at defective
cable), the fault signal will be activated and displayed via a red LED in
the front panel (fault). The signal is available at a
second floating change over contact.
Note!
The fault will not be stored. Once the cause of the fault has been reme-
died, the fault signal goes off.
Dirt beginning to settle on a discharging bar is initially indicated by an
irregular response of the fault signal. This must be kept in mind when
processing the fault signal further.
