• Minimum Run Time: Set the minimum time the motor must have been running
before entering sleep mode.
• Minimum Sleep Time: Set the minimum time the motor must stay in sleep
mode.
• Flow Check Window: Flow check window is the amount of pressure increase
used in the flow check function.
• Flow Check Low Time: Flow check low time defines how long the controller will
run at the setpoint during the flow check function.
• Flow Check High Time: Flow check high time defines how long the controller
will run at Flow Check setpoint during the flow check function.
• Run the No Flow Power Calibration Setup: Start of auto setup of power data for No-Flow Power tuning.
NO FLOW POWER CALIBRATION
A no flow condition can be detected
by monitoring the power consumption
of the pump. Typically a pump’s power
consumption will drop when the pump is run
at no flow. The graph shown below illustrates
a typical pump power curve at the pump
design flow and at no flow.
When the pump is operated at no flow,
the power consumption will follow the
no flow power curve for that specific
pump. The controller monitors the power
consumption of the pump. If the pump’s
power consumption falls to the no flow
power curve, a no flow condition can be
detected by the controller. In order to detect
a no flow condition for various pumps, the no
flow power curve needs to be programmed
into the drive. The No Flow Power Calibration
Setup provides the method to program the
no flow power curve into the controller.
