ƒ Apply the Run (Start) command. The motor should begin to
accelerate. Status display will read Phase A Amps at an increasing
rate.
ƒ When the motor reaches full speed, the “At Speed” LED comes on.
Status display should show a sharp decrease in Phase-A amps.
ƒ If a Bypass Contactor is present (TE…-BP model), the Bypass
Contactor should pull in.
ƒ If the motor does not fully accelerate, decelerates, or stops during
the acceleration period, hit the Stop button immediately and open
the disconnect line.
If Pump-Flex Decel is programmed in F025:
ƒ Remove the Run Command (or hit the Stop button). At-Speed LED
will go out.
ƒ If a Bypass Contactor is present (TE…-BP model), the Bypass
Contactor should drop out.
ƒ Status display should read Phase-A amps increasing as motor
begins to decelerate.
ƒ Motor should begin to slow down. Status display should begin to
show decreasing motor amps.
ƒ When motor reaches Stop Level, starter should turn off. Status
display will again show [0000.]
