* Pressure setting with venting is only possible in function "Vacuum control" if an venting valve is
connected and configurated and vacuum control is started. The venting valve opens automatically
if the actual pressure is at least 10 mbar below the preset pressure. Automatic venting becomes
inactive if vacuum control is stopped (STOP or VENT), setting a pressure value using the command
OUT_SP_1 or if the function is changed. Activate the command 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 due to the change of the mode of operation can occur and to provide appropriate safety
measures, especially if selecting remote operation interferes with a locally operated active process.
