Virtual Linear Pump Setup
Toshiba International Corporation’s
Virtual Linear Pump
algorithm allows for direct and precise
control of pressure, flow rate, or level. This is achieved without the concerns, instabilities, or
complexities that are traditionally associated with pumping system control. This section provides useful
setup and operational information for the
Virtual Linear Pump
system.
The system is initially configured using the (Program
Virtual Linear Pump
Setup Wizard
. Once
the Wizard
is started, it must be completed for normal
Virtual Linear Pump
operations to function.
However, the parameters addressed while using the Wizard or the
Virtual Linear Pump Settings
menu
selection are also accessible via their associated direct access numbers for specific adjustments when
required (see
pg. 148
).
If not using the Wizard to configure the settings of the
Virtual Linear Pump
algorithm, parameter
F390
must first be set to
255: Setup
to accept changes to the
Virtual Linear Pump
parameter settings.
Upon completion of the parameter changes, set parameter
F390
to
1: Direct Mode
or
2: Process Hold
to use the new settings for normal
Virtual Linear Pump
operations (Zero may be selected at
F390
to
save the changes to be used later).
The setup procedure and the Wizard setup screens are shown below.
