4 Operation
Before operating the pump, it is worthwhile configuring the various Podule settings so that they are suitable for the
application.
If the system is designed to operate in pure Parallel Interface Mode, there is no facility to change any of the Podule
settings once the DX pump is installed on the system. The pump is supplied with all settings at factory default values,
as shown in
Table 14 . If any of the Podule settings are to be changed, change them before installing the DX pump on
the system.
The DX pump can be configured using the customer serial system. Section 4.1 details the commands that will be
needed to configure the Podule. Alternatively, use the Edwards TIC Turbo and Instrument Controller or TIC Turbo
Controller. Further information regarding this is detailed in
Section 4.2 .
If the DX pump is operated in pure Parallel Interface Mode and the Podule settings will not be reconfigured, go
straight to
Section 4.3 .
4.1 Configuring the DX pump using serial commands
Refer to Table 14 for a summary of the full set of serial commands. Table 12 details the parameter range and factory
default for each setting. The following sections describe the settings in more detail.
4.1.1 Power limit setting
Table 19 shows the power limit setting options for the DX pumps. The pump is supplied with a default power limit as
shown. If this limit is not suitable for the application, change it to any value between the maximum and minimum
shown.
Send the command as follows (where the 'd' characters represent the value in Watts that is being set. For example,
to set the limit to 90 W, type 90).
The reply will be in the following format:
The Power Limit Setting is now stored in memory within the DX pump.
To check what power limit is set, send a query as follows:
WARNING
Do not operate the DX pump unless it is connected to the vacuum system. The pump rotor rotates
at very high speeds and the rotating blades might not be visible. If the pump is run unconnected,
the pump rotor can cause injury.
