Starting the Package
1.
Power on the VFDs, switching their disconnect switches to the ON position.
Refer to the VFD Owner's Manual.
Each VFD should be in Hand Mode and turned off. Refer to the VFD Owner's Manual for details on
Hand and Auto Mode.
2. Make sure the VFD Setpoint Pressure for the unit is correct. Refer to
page
15.
3. Verify the Standby Activation Speed is correct.
Refer to
"Standby Activation Speed" on page
Isolate out the pumps to find the dead head speed corresponding to the site pressure setpoint.
Add 1-3 HZ to that number to find the speed at which the pumps go into standby mode if they
operate at this frequency for the time period set in the Standby Mode Timer.
If the number calculated is different, update the Standby Activation Speed to the new value. Refer
to
"VFD Parameter Screens 1 & 2" on page 9

If rotation is incorrect, change the phasing in the parameter setting at the VFD.
Refer to the VFD Owner's Manual.

If needed, place each VFD in Hand mode and turn off to adjust the PID Proportional Gain, PID Integral
Time, and PID Differential Time parameters to optimize pump performance for system demand
changes.
