* Pressure setting with venting is only possible in ”Vacuum control” mode
if a venting valve is connected and configured, and vacuum control is
started. The venting valve opens automatically if the actual pressure is
at least 7.5 Torr (10 mbar) below the preset pressure. Automatic vent-
ing becomes inactive if vacuum control is stopped (by pressing ”Esc”),
a pressure value is set using the command OUT_SP_1, or if the basic
mode is changed. Activate the command OUT_SP_V again if neces-
sary.
** If remote operation is selected or deselected, the user has to ensure
that no dangerous status of the system can occur due to the change of
the mode of operation, and must also take appropriate safety precau-
tions, especially if selecting remote operation interferes with a locally
operated active process.
*** After being switched on, the controller is in ”CVC 2” mode by default.
Send ”CVC 3” and ”STORE” to permanently set the controller RS 232C
commands to the extended set ”CVC 3000”.
