Supply voltage matches the rated supply voltage of the unit. 

 

Horsepower and current ratings of the motor and unit match or the 
unit is higher rating. 

 

Initial ramp time and torque adjustments have been checked. 

 

Power lines are attached to the unit input terminals L1, L2 and L3. 

 

Motor leads are connected to the lower terminals T1, T2, and T3. 

 

Appropriate control power is applied and/or control connections 
have been made. 

 

“Power On” light located on the front of the unit turns on when 
control power is applied. 

 

Four 7-segment LED readouts are visible. 

 

The motor’s FLA has been programmed in function F001. 

 

The thermal overload is properly set. (Use F003 and F004 to set OL 
Class.) 

 

The motor area and equipment are clear of people and parts before 
start-up. 

 

ƒ  Apply three-phase power to the unit. The motor should not run until 

the start command is applied. 

ƒ  Apply control power and check that the “Power On” LED comes on. 
ƒ  Status Display should read [0000.] showing no current in Phase A 

(minor flickering of the first digit is common). 

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.]
