Technical Information
Operating Mode
The controller 4UHV for Ion pumps can be operated in three different modes:
Local
Serial
Remote.
The commands sent to the controller (for example, HVON/OFF, Target voltage etc.)
can only be given in the mode chosen, while the data (for example, current,
pressure, voltage etc.) can be read in all the modes.
E.g.: If you select Local mode, the HV channels can only be switched on via the keys
on the Front Panel, but the current supplied can be read via the Front Panel, Serial
and Remote.
Change from one mode to the next can be done either via the Front Panel or a serial
command.
Change from one mode to another can be done with the high voltage switched on.
NOTE
However, the channels switch off if Remote mode is selected but no commands for
switching on are present on the remote connector.
