* Pressure setting with venting is only possible in ”Vacuum control”
mode if a venting valve is connected to the VNC 2 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 pre-
set pressure. Automatic venting becomes inactive if vacuum control
is stopped (by pressing ”Esc”), a pressure value is set using the com-
mand OUT_SP_1, or if the basic mode is changed. Activate the com-
mand OUT_SP_V again if necessary.
** 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 take appropriate safety precautions,
especially if selecting remote operation interferes with a locally oper-
ated active process.
