Apply control power and check that the "Power On" LED comes on.

Status Display should read [0000.] showing no current in Phase A
(minor flickering of the first digit is common).

Apply the Run (Start) command. The motor should begin to
accelerate. Status display will read Phase A Amps at an increasing
rate.

When the motor reaches full speed, the "At Speed" LED comes on.
Status display should show a sharp decrease in Phase-A amps.

The Bypass Contactor should pull in.

If the motor does not fully accelerate, decelerates, or stops during
the acceleration period, push the Stop button immediately and open
the disconnect line.
If Pump-Flex Decel is programmed in F025:

Remove the Run Command (or push the Stop button). At-Speed
LED will go out.

The Bypass Contactor should drop out.

Status display should read Phase-A amps increasing as motor
begins to decelerate.

Motor should begin to slow down. Status display should begin to
show decreasing motor amps.

When motor reaches Stop Level, starter should turn off. Status
display will again show [0000.]
