3: vacuum control with automatic
set vacuum OUT_SP_1 XXXX unit according to preselection
(0001 to 1060 mbar (hPa) or 0001 to 0795 Torr)
set vacuum OUT_SP_V XXXX unit according to preselection
with venting* (0001 to 1060 mbar (hPa) or 0001 to 0795 Torr)
selected frequency OUT_SP_2 XX.X motor frequency in Hz (01.0 to 60.0 in steps
of 0.5 Hz or 99.9 for “HI”)

time for automatic OUT_SP_6 XX:XX hh:mm (hours:minutes)
switching off (VACUU•LAN)
starting process control START
stopping process control STOP X 1: termination of process control

* 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.
