TE2 Series Digital Solid State Soft Starter User Manual 1 | Page
Chapter 1 - Introduction
1.1 General Description
The TE2 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 500% for 20 seconds (Standard Duty)
and up to 500% for 60 seconds (Heavy Duty). The TE2 Series features
smooth, stepless ramp control, which reduces motor inrush current and
excessive wear on the mechanical drive train components. The TE2
Series includes a programming 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 TE2 Series.
By simply adjusting the units’ 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 TE2 Series includes solid-state
electronic overload protection in addition to numerous other protective
features. It requires 120VAC (220VAC optional) control power and uses
dry contact inputs for Start / Stop control. Programmable auxiliary
contacts and provisions for interlocking are also included.
1.1.1 Control Features
Acceleration Adjustments
Programmable Ramp Types:
Voltage Ramp (VR) or closed loop Current Ramp (CR)
