Which of the following is not a benefit of remote monitoring via data transmission devices?
Fill in the blank with the correct option: VFD provides soft start and soft stop that helps ________.
Can a VFD be used as an over-frequency drive when pump performance needs to be increased?
When a VFD is installed with a pump, what happens if the valve for one irrigation zone is closed and another is open?
Fill in the blank with the correct option: Installing a VFD with a pivot ensures that the _______ at the sprinklers remain constant, thereby maintaining high irrigation uniformity.

Q: Can a VFD be used as an over-frequency drive when pump performance needs to be increased?
A: Yes
Q: Can a VFD be used as an over-frequency drive when pump performance needs to be increased?
A: No
Q: Can a VFD be used as an over-frequency drive when pump performance needs to be increased?
A: Yes, but only if the motor has enough reserve power
Q: When a VFD is installed with a pump, what happens if the valve for one irrigation zone is closed and another is open?
A: A pressure sensor notifies the VFD to reduce the pressure, and thereby the speed of the pump.
Q: When a VFD is installed with a pump, what happens if the valve for one irrigation zone is closed and another is open?
A: The pressure decreases in the zone that is open.
Q: When a VFD is installed with a pump, what happens if the valve for one irrigation zone is closed and another is open?
A: The power consumption increases by almost 50% compared with both zones open.
