Introduction
This manual provides and overview of the installation, set-up, and typical
operation of the Allen-Bradley® hydraulic elevator and escalator starter. This
solid- state starter solution is designed to operate 3-phase standard squirrel
cage induction motors and can be connected to a 6- or 12-lead Wye-Delta or
standard 3- or 9-lead motors. Through the use of line or inside-the-delta
control, the solid-state solution can provide ultimate control of the motor. The
advantages of a solid-state solution include the following:
•
Provides smooth motor starting.
•
Reduces current surges on weak electrical systems.
•
Reduces starting torque of the motor, which helps to reduce mechanical
stress on system components.
•
Helps meet both local and regional electrical codes when reduced voltage
starting is a requirement.
•
Eliminates voltage and current spikes associated with traditional Wye-
Delta starters.
•
Maximizes the life of the motor with reduced electrical strain.
•
Reduces general system maintenance requirements for improved
uptime.
Component Overview
The starter is made up of two components, the base controller and a fault
contactor.
