The circuit monitor’s
shift energy log,
viewed in System
Manager software
tracks energy cost per
production unit for up
to three shifts.

● Incorporate Utility curtailment signals
directly to your meter
● Determine the status of loads (on/off)
on your system with respect to the
peak demand periods
● Shed non-essential loads while
maintaining critical processes and
lighting requirements
14
Optimize Equipment Utilization
● The CM4250 and CM4000T circuit monitors provide the information
needed to effectively monitor your equipment to get the most out of your
assets
● Utilize trend information to analyze and balance loading
The circuit monitor’s onboard data logs, uploaded to
System Manager software, can help determine if
proper equipment and lighting shutdown practices
are being followed. This can help reduce
consumption and avoid excessive wear on
equipment, especially on unloaded motors.

15
Optimize Equipment Utilization
● Identify spare capacity within the power system so you can add new
loads and avoid unnecessary capital expenditures
The circuit monitor’s cumulative min/max/avg logs with
forecasting can help determine if new loads can be served
with existing equipment. The trends can be viewed on an
ECC web page (left)
or in System Manager software.

16
Optimize Equipment Utilization
● Extend equipment life by determining whether sensitive equipment is
being exposed to damaging sags/swells
Voltage disturbances, plotted on the ITIC or SEMI
curves can be viewed on an ECC web page.

17
Optimize Equipment Utilization
● Extend motor life by properly
derating motors to account
for the heating effects of
voltage imbalance.
The NEMA MG-1 motor curve, viewable via a circuit
monitor’s ECC web page, shows the derating factors
needed to compensate for voltage imbalance.

Improve System Reliability
● Detect and capture damaging
transients (CM4000T)
● The CM4000T helps minimize
downtime, by generating alarms
to notify you of transients.
● The CM4000T can detect and record
transients (as short as 1 microsecond)
that can cause problems for sensitive,
microprocessor-based devices
● Determine the severity and source of
transients caused by capacitor
switching, DC drive operation,
contactor bouncing, arcing faults,
current interruption
Schneider Electric - Marketing – PowerLogic® CM 4000 Series Circuit Monitors – December 2008
At 512 points/cycle, peak
appears to be 850V
CM4000T shows actual
peak is 2,800V
At 83,333 samples per cycle (at 60 Hz), The
CM4000T captures the true extremes of a
transient.
21
Improve System Reliability
● Quantify the severity of transient activity — The CM4000T provides a
range of information to help quantify the frequency and severity of
transient activity including magnitude, duration, phase, and stress factor
● Transient summary information can be viewed via web pages
Stress calculation lets you see at a
glance the circuits that have
received the greatest stress from
transient overvoltage.
Schneider Electric - Marketing – PowerLogic® CM 4000 Series Circuit Monitors – December 2008
The circuit monitor
categorizes
transients by
magnitude and
duration to help
determine the true
severity of transients
in the system.
22
Improve System Reliability
● Detect and capture sub-cycle events—The circuit monitor’s waveshape
alarm feature detects sub-cycle events that do not exceed the
thresholds of sag/swell alarms including:
● Capacitor switching transients and sub-cycle transfer switch operations
● Non-periodic notching of the waveform
● Loads turning on or off
Schneider Electric - Marketing – PowerLogic® CM 4000 Series Circuit Monitors – December 2008
23
Improve System Reliability
● Identify the source of power quality
disturbances
● Disturbance direction detection, a
patent pending feature, helps locate
the source of a disturbance by
indicating whether it occurred
upstream or downstream of the meter
● Direction information and a statistical
confidence level are added to the
circuit monitor’s event log and
displayed as an alarm in
System Manager
Circuit monitor alarms,
viewed in System
Manager, show a high
level of confidence that
the disturbance
occurred downstream
of the device.

Improve System Reliability
● Detect and measure troublesome
voltage flicker — CM4000T measures
voltage flicker caused by arc furnaces
and welders, and rapidly cycling loads
such as motors, copiers, and printers
● Flicker can:
● Cause headaches and/or stress and
irritability.
● Result in the malfunction of sensitive
equipment.
