2.1 Operating modes
The generator has a number of different operating modes:
 Local mode The high voltage or output current of the generator is set using the
keyboard.
 Remote mode The high voltage or output current of the generator is set and read
via external analogue control signals.
 Fieldbus mode (Optional) The high voltage or output current of the generator is set
and read via a serial communication interface.
 AdvOutC mode (Optional) Advanced Output Control mode. In this mode the high
voltage that is set depends on an analogue control signal, e.g. speed
control of the machine (see Appendix IX).
By using the generator's integrated menu structure, it is possible to switch between the various
operating modes.
Locked mode
If operating in local mode it is possible to (temporarily) lock the operation. This is called ‘locked’
mode. In this mode it is no longer possible to change the output voltage or output current using
the keyboard.
2.2 Control modes
The generator has different ways of controlling the output voltage and current. The generator
can be switched to VC/CV mode or CC mode.
 VC/CV mode Voltage Control or Constant Voltage. The generator will maintain the
set voltage value and the current to be supplied by the generator will
be adjusted to this.
 CC mode Current Control or Constant Current. The generator will maintain the
set current value and the output voltage to be supplied by the
generator will be adjusted to this.
 AdvCC mode (Optional) Advanced Current Control mode. The generator operates
in an intelligent CC mode, with the ability to switch back to the stand-
by state when no object is present below the connected electrodes
(see Appendix VIII).
Operation in Voltage Control mode
When the generator is operating in the VC mode, the desired output
voltage is set on the generator. The generator now maintains the
set output voltage and, depending on the load, adjusts this with a
larger or smaller current. The charging current decreases, however,
if the electrodes become dirty.
