152 P9 ASD Installation and Operation Manual
(Virtual Linear Pump) Auto Start-Stop Delay Timer
Virtual Linear Pump Auto Start-Stop Delay Timer
During a properly configured Virtual Linear Pump operation, this parameter
establishes the time that the Start-Stop criteria of
F388 and F389 must be
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.
Direct Access Number — F387
Parameter Type — Numerical
Factory Default — 5.0
Changeable During Run — Yes
Minimum — 0.1
Maximum — 6553.5
Units — Seconds
(Virtual Linear Pump) Auto Start-Stop Lower Threshold
Virtual Linear Pump Auto Start-Stop Threshold Setting
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)
Direct Access Number — F388
Parameter Type — Numerical
Factory Default — Application-Specific
Changeable During Run — Yes
Minimum — F403 Setting
Maximum — F393 Setting
Units — Selectable at Wizard
(Virtual Linear Pump) Auto Start-Stop Upper Threshold
Virtual Linear Pump Auto Start-Stop Threshold Setting
During a properly configured Virtual Linear Pump operation while in the On
Forward or On Reverse modes (
