3. Status Display should read [0000.] showing no current in Phase A (minor flickering of the first digit is
common).
4. Apply the Start (Run) command. The motor should begin to accelerate. Status display will read Phase A
Amps at an increasing rate.
5. When the motor reaches full speed, the "At-Speed" LED comes on and the Bypass Contactor will close.
Status display should show a sharp decrease in Phase A Amps.

button immediately and open the disconnect.

If Pump-Flex Decel is Disabled (factory default) in F024:
1. Remove the Run Command (or hit the Stop button).
2. At-Speed LED will go out and Bypass Contactor will open. Status display should read [0000.] indicating
no current on Phase A.
