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, wich 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.
