Commands for the Te-VacS
Set Pressure Difference
This command starts the vacuum pump. You must specify the required
vacuum (range: 30 – 700 mBar). This does not apply vacuum to either of the
SPE blocks. If you want to use the fast pumping procedure (see Operating
Manual, Te-VacS), you should use this command in advance of the Apply
Vacuum command. Due to the time needed to build up the vacuum, you
should follow this command with a Wait command.
Apply Vacuum
This command applies the vacuum to the SPE block specified on the General
tab. You must specify the required vacuum (range: 30 – 700 mBar). The
vacuum will be applied until a subsequent Vent Block command is executed.
The vacuum builds up slowly unless you precede this command with a Set
Pressure Difference command. This is equivalent to the soft pumping
procedure (see Operating Manual, Te-VacS - see 1.2.1 “Related
Documentation and Software”, 1-3).
Vent Block
This command vents the vacuum from the SPE block specified on the General
tab. It is used to stop the vacuum separation process.
Deactivate
This command is used to shut down the Te-VacS when you no longer want to
use it in your script or process. It switches off the vacuum pump and vents all
blocks and the internal vacuum container. If you do not specify a Deactivate
command, the Te-VacS will be deactivated automatically when you quit
Freedom EVOware.
Position plate
This command is only relevant if the Te-VacS is fitted with the Repositioner
option. It moves the collection plate for the rear vacuum block into one of four
positions before you apply the vacuum. For more information on this feature,
see 16.35.10 “Te-VacS - PositionPlateRear Command”, 16-118.
Desalting
This command opens the desalter valve to drain the residues. It is only
relevant for Te-VacS versions which are equipped with a desalter valve.
Specify how long you want to open the desalting valve (range: 1 - 60
seconds).
Wait
This causes the separation script to wait for the specified duration.
Command
Sends a firmware command to the Te-VacS. Refer to the firmware
documentation for the device for a complete list of firmware commands (see
also 1.2.1 “Related Documentation and Software”, 1-3).
WARNING
Risk of injury to operating personnel or damage to the equipment
• Take care when sending firmware commands. Sending the wrong commands
can damage the instrument or objects in its workspace, hurt yourself or other
people.
To view or edit the execution parameters again later, right-click on the process
step in the Process Editor and choose Edit Parameters in the context menu.
