1.1 General Description

The TE Series is a digitally programmable solid-state reduced voltage
soft starter. Its six SCR design features a voltage/current ramp with an
anti-oscillation circuit for smooth load acceleration. The SCRs are sized
to withstand starting currents of 350% for 30 seconds and up to 600%
for 10 seconds. The TE Series features smooth, stepless ramp control,
which reduces motor inrush current and excessive wear on the
mechanical drive train components. The TE Series includes a
programmable keypad for setting operating parameters for the ideal
starting cycle and protection features, plus easy to understand
diagnostic LEDs. Starting torque, ramp time, current limit, dual ramp,
and Decel control are standard features on the TE Series, as well as
the integrated Batch Process Timer and Time Clock Controller used for
automated applications. By simply adjusting the unit's starting torque,
ramp time and current limit functions, the starting electrical
characteristics of the motor can be matched to the mechanical
characteristics of the drive train for controlled acceleration of the load.
The TE Series includes solid-state electronic overload protection in
addition to numerous other protective features. It requires 120VAC
(240VAC optional) control power and uses dry contact inputs for Start /
Stop control. Programmable auxiliary contacts and provisions for
interlocking are also included.
