Introduction

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).

Digital Interface

The TE2 Series Soft Starter includes a digital keypad with eight LEDs,
seven command keys, and an LED display with four alphanumeric
digits.

Clears the Trip indication and releases the Trip Relay.
Enters or exits the Program Mode.
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.
Each keypress 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.
Control power is available at A1 and A2
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.
Power is flowing to the motor in the Off mode. See
section 5.6.8.a for additional information.
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 information.
Overcurrent LED lights for three sets of fault conditions:
1) During start, the unit saw current exceeded 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.
One or more of the phase currents dropped below the
threshold during starting or running.
Starter has tripped due to excess heat sink
temperature. This will automatically reset.
Starter has tripped due to the Thermal Register
reaching 0000. The Overload must reset before this
fault can be cleared.
4 digit 7 segment display with a decimal point on the
right side indicating Phase A.
