Features
3. Configure the Pipe Fill Speed
The fill speed is the RPM value that the PS220 will ramp up to and remain at while the function is executing. The default
value is 1000 RPM
NOTES
1. The ramp up speed is set with the Process Control Tune wizard when using any Process Control Mode.
2. When using Basic Speed Control, the ramp up speed is defaulted to 5 seconds. It can be configured manually by ac-
cessing Parameter 23.12 “Acceleration Time”
3. Changing the ramp up time may have an adverse effect on the control mode when the Pipe Fill function is non-func-
tional.
4. Configure the Pipe Fill Stop Value
When using any Process Control Mode this value will be continuously monitored during the execution of the Pipe Fill
function. When this value is achieved the Pipe Fill function will terminate and automatically begin to control the process as
configured.
Example:
The Process control mode is Pressure control, Discharge side. The Process Control Setpoint is 60 PSI. There is a pressure
transmitter a significant distance from where the pump is physically located. The piping is completely empty when the
system is started. The actual pressure measured and displayed is 0PSI. The Pipe Fill Stop Value is 70PSI, the Fill Time is 180
seconds, and the Fill Speed is 1750 RPM.
The PS220 is started, ramps up 1750 RPM. Internally a timer start to count down. After two minutes the pressure slowly
increase in the discharge line and measures 70PSI. The Fill function immediately stops and the PS220 begins to control the
system to the 60PSI setpoint. IN this example it terminated 1 minute before the fill time configured.
The table below lists all of the Parameters used in this function.

Parameter Name Value/Range Notes
83.24
PIPE FILL ENABLE
DISABLE (default)
ENABLE
DI6( Not Functional)
This parameter enables the pipe fill
function when the drive is started.
83.25
PIPE FILL TIME 0 – 65000 sec.
50 sec. (default0]
Maximum total time that the pipe
fill function will execute. It will stop
prior if a value is entered in 83.27
for Process PID control.
83.26
PIPE FILL SPEED 0-20000 Seconds
1000 [default]
Defines the speed the drive will run
at when the pipe fill function is being
executed.
83.27
Pipe Fill Stop Value Default is 0
Defines the actual value used in the
primary PID control mode to stop
the pipe fill function. When this value
is achieved the PS220 will resume
normal pump control. The units are
not shown but are the same as
defined in the PID control mode.
