Introduction
1.1 Overview
1.1.1 Description The MM3 Motor Manager 3 combines control functions normally found in a low voltage
motor control center (MCC) with motor protection. This compact, microprocessor based
device, provides sophisticated control and protective relaying at significant cost savings
over an MCC design using discrete devices.
Standard features simplify maintenance and plant expansion. One MM3 Motor Manager 3
is required for every starter unit in the MCC. The contactor can be energized and de-
energized using the MM3 Motor Manager 3's direct-wired inputs or via the serial port. Full
voltage non-reversing, full voltage Reversing, two-speed, autotransformer, inverter, wye-
delta, slip ring, and part winding type starters may be completely controlled by the MM3
Motor Manager 3 using the two contactor outputs.
Motor protection is included for the most common causes of failure to prevent costly
shutdowns and rewinds. These include three-phase overload, stalled rotor, ground fault
and loss of phase.
A two-wire RS485 Modbus communications port is provided for high speed
communications with a complete line-up of MCCs. Any MM3 Motor Manager 3 may be
interrogated on demand to determine both actual and setpoint operating parameters.
Fast response time to a request for alarm or trip status makes real time control of a
complete process possible. Statistical recording of running hours and number of starts and
trips assists with predictive maintenance scheduling.
1.1.2 Features The MM3 Motor Manager 3 has been developed with economy in mind. The customer is
able to choose from different options to achieve maximum benefit from the relay when
integrated into the process environment. The standard MM3 Motor Manager 3 comes with

OVERVIEW CHAPTER 1: INTRODUCTION
three-phase overload protection (49/51), single-phase, four (4) control inputs (start, stop,
local isolator, contactor A status) plus 4 programmable inputs. The full version adds the
following additional features:
• Second contactor control (wye/delta, two speed, reversing, etc.) including all
timers, relays and control inputs
• Undercurrent/underpower protection (ANSI 37)
• Thermistor (ANSI 49) input which accepts PTC and NTC thermistor types
• Analog input/output
• Six (6) additional programmable inputs plus two (2) control inputs
