The
Initi@tives are comprehensive multi-industry trade expositions
and this was only the second such event to take
place in the U.S. Over 1,400 attendees perused new technologies
that help businesses do more with less energy,
meet code and legislative requirements, and prepare for
future trends.
Space limitations prevent reviewing every device on
display, but several items stood out. Preventive maintenance
(PM) plays a critical role in lengthening motor life
and promoting energy efficiency. Good PM typically demands
good plant records.
The TeSys T Motor Management System
by Telemecanique combines
primary motorprotection
needs
with the ability
to record motor
history, statistics,
and timestamped
faults,
thus giving a
real-time view of
motor operation.
The system lets
plant personnel
analyze existing faults and anticipate
future performance to avoid nuisance trips,
reduce downtime, and do less maintenance
and repair.
The motor-management system monitors and controls
six motor functions while guarding against overload, peak
current, and excessive power consumption. It can report
using any of five fieldbus types: Ethernet, Modbus, CANopen,
DeviceNet, and Profibus, without auxiliary modules
or communication gateways. With a complete motor
operating history at their fingertips, PM specialists can adjust
maintenance schedules as needed,
paying more attention to motors seeing
frequent overloads while extending
schedules for those lightly loaded.
One popular display by the Juno
Lighting Group of Schneider Electric
used different types of lighting, including
halogen and LED, in simulated
homes and store fronts. The light
sources let visitors see how different
types of light affect the surroundings.
APC by Schneider Electric displayed
its line of critical power and cooling devices for home,
office, data center, and factory floor. Green is in, and the
Efficient Enterprise initiative is APC’s approach to help
companies use less power. Some data centers have
seen energy use drop 30% by initiating the Efficient Enterprise
program.
While Telemecanique is Schneider Electric’s wellknown
automation and motor-control brand in Europe,
here in the U.S. the firm is better known for its Square D
brand. For example, the Model 6 Motor Control Center
now carries the TeSys T Motor Management System with
internal data communication, linking the control directly
into five different industrial networks. In
addition, an RJ-45 jack mounted on the
controller lets plant personnel connect
a laptop or PC or HMI. The system supports
six discrete inputs and three relay
outputs for logic I/O control, though
additional modules can extend that
capacity.
Model 6 PowerPact main circuit
breakers have current ratings from 800
to 2,500 A. Available in M, P, and R-frame
styles, the PowerPact breakers feature
Micrologic electronic trip units. Micrologic control lets
two PowerPact breakers work in tandem to automatically
switch plant power from utility feed to backup generator
in a main-tie-main configuration.
