Virtual Linear Pump Start/Stop Mode
Program Virtual Linear Pump Start and Stop Points
During a properly configured Virtual Linear Pump operation, this parameter
Enables/Disables the ability of the system to receive transducer input to
manage system starts and stops as it pertains to the process variable.
This parameter is also used to select the ASD response (Stop or Start) upon
meeting the criteria of
F388
On Forward = Run ASD while measured signal is
ASD upon reaching
F389
setting.
On Reverse = Run ASD while measured signal is
upon reaching
F388
setting.
Settings:
0 — Off
1 — On (Forward Acting)
2 — On (Reverse Acting)
WARNING
The Auto Start-Stop operating mode may result in the
unexpected Start or Stop of the motor. Signs to this effect are
to be posted at the location of the motor/pump.
Virtual Linear Pump Start-Stop Delay Timer
Program Virtual Linear Pump Start and Stop Points
During a properly configured Virtual Linear Pump operation, this parameter
establishes the time that the Start-Stop criteria of
maintained to activate the Auto Start-Stop function.
This feature is used to minimize system responses to rapid fluctuations in the
feedback signal.
See
F385
for additional information on this parameter.
Virtual Linear Pump Low Start/Stop Point
Program Virtual Linear Pump Start and Stop Points
During a properly configured Virtual Linear Pump operation while in the On
Forward or On Reverse modes (F385), this parameter establishes the lower
level of the Auto Start-Stop threshold.
See
F385
for additional information on this parameter.
The unit of measure for this parameter may be one of the following types — the
type is selected while running the Virtual Linear Pump Setup Wizard.
• PSI
• GPM
• Inches of Water Column
• Feet of Water Column
• CFM
• °C
• °F
• Custom
(Custom selection allows for three character spaces to be populated from the 26
alphabet and 13 special characters)
