It is best to operate the motor at its full load starting conditions to 
achieve the proper time, torque and ramp settings. Initial factory settings 
are set to accommodate general motor applications and provide basic 
motor protection. Advanced features must be enabled via programming. 
The only parameter that MUST be set by the user is motor FLA (F001). 

 

The TE Series Soft Starter includes an intuitive, digital keypad with 
eight LEDs, seven command keys, and an LED display with four 
alphanumeric digits.

Reset 

Clears the Trip indication and releases the Trip Relay. 

Fn 

Enters or exits the Program Mode.  

Up and 

Down 

Arrows 

Navigates through the Status Display Mode, scrolls up 
and down through the Function List, increases or 
decreases the value of the active (flashing) digit and 
scrolls through the fault history. When entering values, 
holding the key down for more than 2 seconds will 
activate Auto-step, which increases its rate the longer 
the key is held down. 

Right 

and Left

Arrows 

Each key press shifts the active (flashing) digit to the 
right or left by one position, allowing you to change 
higher values of functions without waiting to Auto-step 
though large numbers. 

Power 

On 

Control power is available at A1 and A2 

At 

Speed 

The motor is at full power and the Bypass Contactor 
has been commanded to pull in. 
The SCRs are at full conduction and current has 
dropped. 

Shunt 

Trip 

Two or more SCRs in opposing phases have shorted, 
and power is flowing to the motor in the Off mode. See 
section 8 for additional concerns. 

Shorted

SCR 

There is no voltage drop across at least one SCR 
phase assembly, indicating that at least one SCR is 
shorted. See section 8 for additional concerns 

Over 

Current 

Overcurrent LED lights for three sets of fault conditions: 

1) During start, the unit saw current exceed the 

normal rate of increase in the first 250ms. 

2) During Run, current exceeded either the OC setting 

in F042 for the delay set in F043. This LED will be 
accompanied by oCA, oCC or oCd on the display. 

3) The unit has seen a Short Circuit exceeding 10x 

FLA for 12.5ms. This LED will be accompanied by 
SCA, SCC or SCD display. 

Phase 

Loss 

One or more of the phase currents dropped below the 
threshold during starting or running. 

Over 

Temp 

Starter has tripped due to excess heat sink 
temperature. This will automatically reset. 

Over 
Load 

Starter has tripped due to the Thermal Register 
reaching 0000. The Overload must reset before this 
fault can be cleared.
