Product Overview
Manual Objectives This manual is intended for use by personnel familiar with Medium Voltage and
solid-state power equipment. The manual contains material which will allow the
user to operate, maintain and troubleshoot the MV Dialog Plus
TM
family of
controllers. The family consists of the following Bulletin numbers: 1503D,
1560D and 1562D.
Documentation The following Rockwell Automation publications provide pertinent
information for the MV Dialog Plus:
• MVB-5.0 General Handling Procedures for MV Controllers
• 1500-UM055B-EN-P Medium Voltage Controller – Two-High cabinet
• 1502-5.0 Maintenance Instruction Manual – Centerline
Medium Voltage Contactors (400 A size)
• 1502-UM051B-EN-P Maintenance Instruction Manual – Centerline
Medium Voltage Contactors (800 A size)

Specifications
Description The MV Dialog Plus is a solid-state, three-phase, AC line controller. It is
designed to provide microprocessor-controlled starting and stopping of
standard three-phase, squirrel-cage induction motors, using the same control
module (in most cases) as the Allen-Bradley Bulletin 150 SMC Dialog Plus.
1503D – Chassis Mount Retrofit Controller
A chassis-mount medium voltage solid-state controller designed to mount in
an OEM or customer supplied structure, and designed to work in conjunction
with an existing or OEM/customer supplied starter. It is comprised of
several modular components, including:
• Frame-mounted or loose power stacks including gate driver boards
• Loose interface and voltage divider/feedback boards
• Fiber optic cables for SCR firing
• Microprocessor based control module
• Vacuum bypass contactor
1560D – Retrofit Controller
A medium voltage solid-state controller designed to work in conjunction
with an existing customer-supplied starter. It includes:
• Tin-plated, copper, horizontal power bus (optional)
• A continuous, bare copper ground bus
• Power electronics
• A bypass vacuum contactor
• A low voltage control panel complete with microprocessor-based control module
• Top and bottom plates to accommodate power cables.
Note: See Interlocking, page 2-8.
