Operating Mode
The controller 4UHV for ion pumps can be operated in three different
modes:
ƒ
Local
ƒ Serial
ƒ
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.
NOTE
Change from one mode to another can be done with the high voltage switched
on. However, the channels switch off if Remote mode is selected but no
commands for switching on are present on the remote connector.
Selecting “Operating Mode” from Front Panel
To display the current mode, press the Mode key briefly (less than 2
seconds).
To change mode, press the Mode key again. The three modes will be
displayed in a cyclic fashion: Local, Serial, Remote.
After selecting the required mode, wait approximately 5 seconds to
return to the previous screen.
