4. Operation
Before switching on the unit, the operator must make sure that installation
and connections have been properly made. If yes, the supply voltage can
be switched on.
The high voltage generator is operated by means of five operating keys
located in the front panel and a two line display.
4.1 Start-up
Warning!
Depending on the parameter setting <Autom. Start>, high voltage may be
applied immediately after activating the supply voltage.
Use the rocker switch to switch on the high voltage generator. Operation of
the unit is indicated by the display message appearing. The generator
operates alternatively in the voltage constant or the current constant
operating mode.
If all necessary operating parameters have been correctly set, high
voltage may be released via the <
> button. The LED below the button
will light up. High voltage is now applied at the bars or at the high voltage
output.
Output voltage and output current are monitored via the display.
In the voltage constant operating mode, the top line shows the actual
voltage value and the bottom line shows the actual current value. In the
current constant operating mode, the top line shows the actual current
value and the bottom line shows the actual voltage value.
