The PM2200 series meter supports many features, a few of the features are listed
below:
• Self guided LCD display and navigation
• Energy accounting and balancing
• Measurement of both True PF and Displacement PF
• Active, reactive, and apparent energy readings
• Min/Max values of instantaneous parameters with timestamp.
• Cybersecurity: The meter supports the disabling of RS-485 port through front
panel keys to prevent unauthorized access. Toggle the RTU devices in case
of limited availability of nodes in software system.
• SnapShot: The meter features include snapshot, which captures values of
average voltage, average current, total active power, and delivered energy
based on configured time in HH.MM format.
• Suppression current: This is the minimum current at which the meter starts
functioning. The meter can be configured to disregard the measurement of

Meter wiring considerations

Direct connect voltage limits
You can connect the meter’s voltage inputs directly to the phase voltage lines of
the power system if the power system’s line-to-line or line-to-neutral voltages do
not exceed the meter’s direct connect maximum voltage limits.
The meter's voltage measurement inputs are rated by the manufacturer for up to
277 V L-N / 480 V L-L. However, the maximum voltage allowed for direct
connection may be lower, depending on the local electrical codes and regulations.
As per installation category II / III the maximum voltage on the meter voltage

18 NHA2778902-11
Hardware references EasyLogic™ PM2200 series

measurement inputs should not exceed 277 V L-N / 480 V L-L for CAT III and 347
V L-N / 600 V L-L for CAT II.
If your system voltage is greater than the specified direct connect maximum
voltage, you must use VTs (voltage transformers) to step down the voltages.

Balanced system considerations

In situations where you are monitoring a balanced 3-phase load, you may choose
to connect only one or two CTs on the phase(s) you want to measure, and then
configure the meter so it calculates the current on the unconnected current
input(s).
NOTE: For a balanced 4-wire Wye system, the meter’s calculations assume
that there is no current flowing through the neutral conductor.

Balanced 3-phase Wye system with 2 CTs

The current for the unconnected current input is calculated so that the vector sum
for all three phases equal zero.

Balanced 3-phase Wye or Delta system with 1CT

The currents for the unconnected current inputs are calculated so that their
magnitude and phase angle are identical and equally distributed, and the vector
sum for all three phase currents equal zero.

20 NHA2778902-11
Hardware references EasyLogic™ PM2200 series

NOTE: You must always use 3 CTs for 3-phase 4-wire center-tapped Delta or
center-tapped open Delta systems.

RS-485 wiring
Connect the devices on the RS-485 bus in a point-to-point configuration, with the
(+) and (-) terminals from one device connected to the corresponding (+) and (-)
terminals on the next device.

RS-485 cable
Use a shielded 2 twisted pair or 1.5 twisted pair RS-485 cable to wire the devices.
Use one twisted pair to connect the (+) and (-) terminals, and use the other
insulated wire to connect the C terminals
The total distance for devices connected on an RS-485 bus should not exceed
1000 m (3280 ft).

RS-485 terminals
C Common. This provides the voltage reference (zero volts) for the data plus and data minus
signals

Shield. Connect the bare wire to this terminal to help suppress signal noise that may be
present. Ground the shield wiring at one end only (either at the master or the last slave
device, but not both.

- Data minus. This transmits/receives the inverting data signals.

+ Data plus. This transmits/receives the non-inverting data signals.

NOTE: If some devices in your RS-485 network do not have the C terminal,
use the bare wire in the RS-485 cable to connect the C terminal from the
meter to the shield terminal on the devices that do not have the C terminal.

Pulse output
NOTE: Applicable only for PM2210 meter model
The meter is equipped with one pulse output port (D1+, D1-).
You can configure the pulse outputs for use in the following application:
• energy pulsing applications, where a receiving device determines energy
usage by counting the k_h pulses coming from the meter’s pulse output port.
One pulse output can handle voltage less than or equal to 40 V DC (20 mA
maximum). For higher voltage applications, use an external relay in the switching
circuit.

Status input (DI) applications

Status inputs are typically used for monitoring the status of external contacts or
circuit breakers and multi-tariff applications.
The meter’s status inputs require either an external voltage source or whetting
voltage (provided in the meter) to detect the status input’s ON/OFF state. The
meter detects an ON state if the external voltage appearing at the status input is
within its operating range.

Alarms
Alarms overview
NOTE: Applicable only for PM2230 meter model
An alarm is the meter’s means of notifying you when an alarm condition is
detected, such as an error or an event that falls outside of normal operating
conditions. Alarms are typically setpoint-driven and can be programmed to
monitor certain behaviors, events or unwanted conditions in your electrical
system.
You can configure your meter to generate and display high, medium and low
priority alarms when predefined events are detected in the meter’s measured
values or operating states. Your meter also logs the alarm event information.
The meter ships with some alarms already enabled from the factory. Other alarms
need to be configured before the meter can generate alarms.
Customize meter alarms as required, such as changing the priority. You can also
create custom alarms using the advanced features of your meter.

than 4 times in one second or more than 10 times in ten seconds. In this case,
you must re-enable the alarm using the display or ION Setup.

Standard alarms
Standard alarms are setpoint-driven alarms which monitor certain behaviors,
events or unwanted conditions in your electrical system.
Standard alarms have a detection rate equal to the 50/60 meter cycle, which is
nominally 1 second if the meter’s frequency setting is configured to match the
system frequency (50 or 60 Hz).
Many of the standard alarms are three-phase alarms. Alarm setpoints are
evaluated for each of the three phases individually, but the alarm is reported as a
single alarm. The alarm pickup occurs when the first phase exceeds the alarm
pickup magnitude for the pickup time delay. The alarm is active as long as any
phase remains in an alarm state. The alarm dropout occurs when the last phase
drops below the dropout magnitude for the dropout time delay.

NHA2778902-11 45
EasyLogic™ PM2200 series Alarms

Example of over and under setpoint (standard) alarm operation

The meter supports over and under setpoint conditions on standard alarms.
A setpoint condition occurs when the magnitude of the signal being monitored
crosses the limit specified by the pickup setpoint setting and stays within that limit
for a minimum time period specified by the pickup time delay setting.
The setpoint condition ends when the magnitude of the signal being monitored
crosses the limit specified by dropout setpoint setting and stays within that limit for
a minimum time period specified by dropout time delay setting.

Over setpoint
When the value rises above the pickup setpoint setting and remains there long
enough to satisfy the pickup time delay period (ΔT1), the alarm condition is set to
ON. When the value falls below the dropout setpoint setting and remains there
long enough to satisfy the dropout time delay period (ΔT2), the alarm condition is
set to OFF.

before, during or after the alarm period.

Under setpoint
When the value falls below the pickup setpoint setting and remains there long
enough to satisfy the pickup time delay period (ΔT1), the alarm condition is set to
ON. When the value rises above the dropout setpoint setting and remains there
long enough to satisfy the dropout time delay period (ΔT2), the alarm condition is
set to OFF.

before, during or after the alarm period.

Maximum allowable setpoint

The meter is programmed to prevent user data entry errors, with set limits for the
standard alarms.
The maximum setpoint value you can enter for some of the standard alarms
depends on the voltage transformer ratio (VT ratio), current transformer ratio (CT
ratio), system type (i.e., number of phases) and/or the maximum voltage and
maximum current limits programmed at the factory.
NOTE: VT ratio is the VT primary divided by the VT secondary and CT ratio is

Meter resets
Meter resets
Resets allow you to clear various accumulated parameters stored on your meter
or reinitialize the meter or meter accessories.
Meter resets clear your meter’s onboard data logs and other related information.
Resets are typically performed after you make changes to the meter’s basic setup
parameters (such as frequency, VT/PT or CT settings) to clear invalid or obsolete
data in preparation for putting the meter into active service.

Meter initialization
Meter Initialization is a special command that clears the meter’s energy, power,
demand values, and meter operation timer.
It is common practice to initialize the meter after its configuration is completed,
before adding it to an energy management system.
After configuring all the meter setup parameters, navigate through the different
meter display screens and make sure the displayed data is valid then perform
meter initialization.
NOTE: You can perform meter initialization using ION setup and secured

Real-time readings
The meter measures currents and voltages, and reports in real time the RMS
(Root Mean Squared) values for all three phases and neutral.
The voltage and current inputs are continuously monitored at a sampling rate of
64 samples per cycle. This amount of resolution helps enable the meter to provide
reliable measurements and calculated electrical values for various commercial,
buildings and industrial applications.

Energy measurements
The meter provides fully bi-directional, 4-quadrant energy metering.
The meter stores all accumulated active, reactive and apparent energy
measurements in nonvolatile memory:
The meter provides both per phase and total values of energy.
Total energy:
• kWh, kVARh, kVAh (delivered)
• kWh, kVARh, kVAh (received)
• kWh, kVARh, kVAh (delivered + received)
• kWh, kVARh, kVAh (delivered - received)

(3PH4W Opn Dlt Ctr Tp, 3PH4W Dlt Ctr Tp, 3PH4W Wye Ungnd,
3PH4W Wye Gnd, and 3PH4W Wye Res Gnd) only. For other configurations, the
energy per phase is not displayed on HMI and obtains as "0" through
communication.

Quadrant based VARh

NOTE: Applicable only for PM2220/PM2230 meter models
Quadrant based reactive energy values are available only on communication.
These are not available on meter display. These reactive energies are for Q1, Q2,
Q3, and Q4 quadrants.
On communication quadrant based reactive energies will be recorded as follows:
• Q1 (00 to 90 Degree) = Q1 VARh , Del
• Q2 (90 to 180 Degree) = Q2 VARh , Del
• Q3 (180 to 270 degree) = Q3 VARh, Rec
• Q4 (270 to 360 degree) = Q4 VARh , Rec
If energy is cleared, all quadrant based VARhs will be cleared.

Min/max values
When the readings reach their lowest or highest value, the meter updates and
saves these min/max (minimum and maximum) quantities in non-volatile memory.
The meter’s real-time readings are updated once every 50 cycles for 50 Hz
systems, or once every 60 cycles for 60 Hz systems.

Power demand
Power demand is a measure of average power consumption over a fixed time
interval.
NOTE: If not specified, references to demand are assumed to mean power
demand.
The meter measures instantaneous consumption and can calculate demand using
various methods.

Power demand calculation methods

Power demand is calculated by dividing the energy accumulated during a
specified period by the length of that period.
How the meter performs this calculation depends on the method and time
parameters you select (for example, timed rolling block demand with a 15-minute
interval and 5-minute subinterval).
To be compatible with electric utility billing practices, the meter provides the
following types of power demand calculations:
• Block interval demand
• Synchronized demand
• Thermal demand
You can configure the power demand calculation method from the display or
software.

NHA2778902-11 61
EasyLogic™ PM2200 series Measurements and calculations

Block interval demand

For block interval demand method types, you specify a period of time interval (or
block) that the meter uses for the demand calculation.
Select/configure how the meter handles that interval from one of these different
methods:

Type Description

Timed Sliding Block Select an interval from 1 to 60 minutes (in 1-minute increments). If
the interval is between 1 and 15 minutes, the demand calculation
updates every 15 seconds. If the interval is between 16 and 60
minutes, the demand calculation updates every 60 seconds. The
meter displays the demand value for the last completed interval.

Timed Block Select an interval from 1 to 60 minutes (in 1-minute increments). The
meter calculates and updates the demand at the end of each
interval.
Timed Rolling Block Select an interval and a subinterval. The subinterval must divide
evenly into the interval (for example, three 5-minute subintervals for
a 15-minute interval). Demand is updated at the end of each
subinterval. The meter displays the demand value for the last
completed interval.

Block interval demand example

The following illustration shows the different ways power demand is calculated
using the block interval method. In this example, the interval is set to 15 minutes.

Measurements and calculations EasyLogic™ PM2200 series

Synchronized demand
You can configure the demand calculations to be synchronized using an external
pulse input, a command sent over communications, or the device’s internal real-
time clock.

Type Description

Command This method allows you to synchronize the demand intervals of multiple
synchronized demand meters on a communications network. For example, if a programmable
logic controller (PLC) input is monitoring a pulse at the end of a demand
interval on a utility revenue meter, you can program the PLC to issue a
command to multiple meters whenever the utility meter starts a new
demand interval. Each time the command is issued, the demand readings
of each meter are calculated for the same interval.
Clock synchronized This method allows you to synchronize the demand interval to the meter’s
demand internal real-time clock. This helps you synchronize the demand to a
particular time, typically on the hour (for example, at 12:00 am). If you
select another time of day when the demand intervals are to be
synchronized, the time must be specified in minutes from midnight. For
example, to synchronize at 8:00 am, select 480 minutes.

NOTE: For these demand types, you can choose block or rolling block
options. If you select a rolling block demand option, you need to specify a
subinterval.

Thermal demand
Thermal demand calculates the demand based on a thermal response, which
imitates the function of thermal demand meters.
The demand calculation updates at the end of each interval. You can set the
demand interval from 1 to 60 minutes (in 1-minute increments).

Thermal demand example

The following illustration shows the thermal demand calculation. In this example,
the interval is set to 15 minutes. The interval is a window of time that moves
across the timeline. The calculation updates at the end of each interval.

Current demand
The meter calculates current demand using the block interval, synchronized or
thermal demand methods.
You can set the demand interval from 1 to 60 minutes in 1 minute increments (for
example, 15 minutes).

NHA2778902-11 63
EasyLogic™ PM2200 series Measurements and calculations

Predicted demand
The meter calculates predicted demand for the end of the present interval for kW,
kVAR, and kVA demand, taking into account the energy consumption so far within
the present (partial) interval and the present rate of consumption.
Predicated demand is updated according to the update rate of your meter.
The following illustration shows how a change in load can affect predicted demand
for the interval. In this example, the interval is set to 15 minutes.

A Beginning of interval E Change in load

B Demand for last completed interval F Predicted demand if load is added

during interval; predicted demand
increases to reflect increased demand
C 15-minute interval G Predicted demand if no load is added
D Partial interval H Time

Peak demand
The meter records the peak (or maximum) values for kWD, kVARD, and kVAD
power (or peak demand).
The peak for each value is the highest average reading since the meter was last
reset. These values are maintained in the meter’s non-volatile memory.
The meter also stores the date and time when the peak demand occurred.

Timer
The meter supports an active load timer, meter operation timer, and run time.

Active load timer

Active load timer shows how much time a load has been running, based on the
specified minimum current for the load timer setpoint setting.

Meter operation timer

Meter operating timer shows how long the meter has been powered up.

EasyLogic™ PM2200 series Multi-tariff

Multi-tariff
NOTE: Applicable only for PM2230 meter model
The multi-tariff feature allows you to set up different tariffs for storing energy
values.
The energy values for different tariffs are stored in registers that correspond to
each of those tariffs.

Multi-tariff example
The multi-tariff feature can be used when a utility has set up tariff schedules with
different rates based on what day or time of day energy is consumed.

Power

Time

Cost

Tariff energy containers

T1 T2 T3 T4

T1 T2 T3 T4

In the above illustration, the area under the power curve equals the energy
consumed.
Typically, the utility sets tariff schedules so the cost of energy is higher during high
demand or high energy consumption times. How these “tariff energy containers”
are configured determines how fast these containers fill, which correlates to
increasing energy costs. The price per kWh is lowest at tariff T1 and highest at
tariff T2.

Multi-tariff implementation
The meter supports configuration of up to 4 different tariffs to measure and
monitor energy usage that can be used in billing or cost applications.
There are three different tariff modes you can use to activate the multi-tariff
registers:
• Command mode
• Time of Day mode
• Input mode

66 NHA2778902-11
Multi-tariff EasyLogic™ PM2200 series

Command mode overview

You can use command mode to send a Modbus command to the device which
sets the active tariff.
The active tariff is applied to the measured energy until you send another Modbus
command that sets a different tariff.
Search for your meter’s Modbus register list at www.se.com to download the
Modbus map.

Time of day mode overview

You can use time of day mode to create a tariff schedule that specifies where the
meter stores energy or input metered data, based on the time of year (month,
day), the type of day (every day, weekend, weekday or a specific day of the week),
or time of day.
The data collected from the different tariffs can then be used in energy audits or
similar costing and budget planning purposes.

Time of day mode tariff validity

A valid time of day tariff has certain conditions and limitations:
• Each tariff must cover a unique time period (tariffs cannot overlap), but there
can be periods with no tariff.
• Any number of tariffs, from none to the maximum number of tariffs, can be
applied.
• Time of day tariffs do not adjust for daylight savings time.
• Time of day tariffs include February 29th in leap years (however, it is not
recommended to have February 29th as a start or end date, as that tariff
would be invalid for non-leap years.
• Except for leap years, tariff dates are not year-specific; if you wanted to
create a tariff that starts on the first Monday in August, you need to enter the
date for that year, then manually update the tariff information for the
subsequent years.
Your device performs validation checks as you enter tariff information; it prompts
you to change the information that you have entered or set the tariff to disabled if
the tariff configuration is invalid. These checks can include:
• Start and end times must be different (for example, you cannot create a tariff
that starts at 02:00 and also ends at 02:00).
• Start time can only be earlier than end time for tariffs that are applied every
day. You can create a daily tariff that starts at 06:00 and ends at 02:00, but
these times are only valid for the Everyday tariff and invalid for the other tariff
types.
• Start day must be earlier than end day if the days are in the same month. You
cannot create a tariff that starts June 15 and ends June 12.

Time of day tariff creation methods

You can create time of day tariffs using one of the two methods, or a combination
of these methods:
• Time of year tariffs divide the year into multiple sections (usually seasons),
where each section has one or more day types. For example, a four tariff
configuration using this method could have Summer and Winter seasons that
also use different weekend and weekday tariffs.

NHA2778902-11 67
EasyLogic™ PM2200 series Multi-tariff

• Daily tariffs can divide days by day of the week, a weekday, a weekend, or
every day, and can specify the time of day. For example, a four tariff
configuration could have every day in the year divided into six-hour tariff
periods or could have two tariffs for weekends and two tariffs for weekdays.
You can combine these methods if, for example you wanted to create a tariff that
applies on Mondays from January 1 to June 30, from 09:00 to 17:00. However,
since only one tariff can be applied at any time, you cannot use an everyday or
weekday tariff type because you already specified a tariff for the time periods
09:00 to 17:00.
Depending on how you configure the tariffs and the maximum number of tariffs
supported by your meter, you may not be able to assign tariffs for the entire year,
potentially leaving time gaps that do not have any tariff assigned to them.

Example tariff configurations for a four-tariff system

In these examples, four tariffs are used to cover the entire year (there are no time
periods that do not have an associated tariff).
Configuration 1: four tariffs with weekdays and weekends

Tariff Type Start date End date Start time End time

1 Weekend June 21 December 20 00:00 23:59

2 Weekend December 21 June 20 00:00 23:59
3 Weekday June 21 December 20 00:00 23:59

4 Weekday December 21 June 20 00:00 23:59

NOTE: The end time of 23:59 is actually 23:59:59, or just before midnight.
All weekend days fall into one of two different tariffs, depending on the date. All
weekdays fall into one of two different tariffs, depending on the date. This
configuration does not use tariffs based on the time of day, or any day types other
than weekend or weekday.
Example dates and corresponding tariffs:
• Friday, June 29 = tariff 3
• Sunday, November 28th = tariff 1
Configuration 2: one season for weekends, with off-peak and shoulder hours, two
seasons for weekdays, with shoulder hours

Tariff Type Start date End date Start time End time

1 Every day January 1 December 31 23:00 04:59

2 Weekdays May 1 September 20 00:00 22:59

3 Weekdays October 1 April 30 05:00 22:59

4 Weekends January 1 December 31 05:00 22:59

All days have a tariff applied between 23:00 and 04:59, corresponding to off-peak
hours. All weekend days have a tariff applied from 05:00 to 22:59, corresponding
to shoulder hours. All weekdays fall into one of two seasons (summer or winter),
and have two tariffs applied throughout the day.
Example dates and corresponding tariffs:
• Wednesday, March 21, 08:00 = tariff 3
• Tuesday, January 10, 21:00 = tariff 3
• Sunday, June 24, 14:00 = tariff 4
• Friday, August 17, 00:00 = tariff 1

Input mode overview

You can use input mode to have the digital inputs of the device set to know which
tariff is applied to the energy that is presently being consumed.
The number of different tariffs that can be applied is determined by the number of
available digital inputs and the total number of tariffs supported by your device.

Digital input assignment for input control mode

You need to assign one or more digital inputs with non-exclusive associations to
define the active tariff.
If a digital input is used for multi-tariff, it cannot be used for an exclusive
association (such as Demand Sync), but digital inputs can be shared with a non-
exclusive association (such as Alarms). To make a digital input available for
setting tariffs, any conflicting associations must be manually removed at the
source of the original association.
The digital inputs are used as binary counters to identify the appropriate tariff,
where off = 0 and on = 1, and most significant bit (MSB) is digital input 2 and least
significant bit (LSB) is digital input 1. By this definition, digital input 1 must be
associated with the multi-tariff feature in order to set the tariff to Input mode.

Active tariff control mode

The active tariff is controlled based on the tariff mode.
• When the meter is set to command mode, the active tariff is controlled by the
Modbus commands from your energy management system or other Modbus
master.
• When the meter is set to input mode, the active tariff is controlled by the
status of the digital inputs.
• When the meter is set to time of day mode, the active tariff is controlled by the
day type, the start and end times, and the start and end dates.

Configuring time of day mode tariffs using the display

When the meter is set to time of day for tariffs, the active tariff is determined by the
day type, the start and end times, and the start and end dates.
The time of day tariff is not a calendar; the meter does not calculate the
corresponding day of the week to a specific date, but February 29th is considered
a valid date if you are programming the meter during a leap year.
When you enter tariff times using the front panel, be aware that the displayed
minute value includes the entire minute. For example, an end time of 01:15
includes the time from 01:15:00 through 01:15:59. To create a tariff period that
starts right after this, you must set the next tariff start time to 01:16. Although it
may appear that there is a gap between these tariffs, there is not.

Power quality EasyLogic™ PM2200 series

Power quality
Harmonics overview
This section describes the meter’s power quality features and how to access
power quality data. The meter measures voltage and current harmonics up to the
15th harmonic and 31st harmonic, and calculates Total Harmonic Distortion (THD
%).
Harmonics are integer multiples of the fundamental frequency of the power
system. Harmonics information is required for compliance to system power quality
standards such as EN50160 and meter power quality standards such as IEC
61000-4-30.
The meter measures fundamental and higher harmonics relative to the
fundamental frequency. The meter’s power system setting defines which phases
are present and determines how line-to-line or line-to-neutral voltage harmonics
and current harmonics are calculated.
Harmonics are used to identify whether the supplied system power meets required
power quality standards, or if non-linear loads are affecting your power system.
Power system harmonics can cause current flow on the neutral conductor, and
damage to equipment such as increased heating in electric motors. Power
conditioners or harmonic filters can be used to minimize unwanted harmonics.

Total harmonic distortion %

Total harmonic distortion (THD%) is a measure of the total per-phase voltage or
current harmonic distortion present in the power system.
THD% provides a general indication of the quality of a waveform. THD% is
calculated for each phase of both voltage and current.

Harmonic content calculations

Harmonic content (HC) is equal to the RMS value of all the non-fundamental
harmonic components in one phase of the power system.
The meter uses the following equation to calculate HC:

HC = (H2)2 + (H3)2 + (H4)2 ...

THD% calculations
THD% is a quick measure of the total distortion present in a waveform and is the
ratio of harmonic content (HC) to the fundamental harmonic (H1).
By default, the meter uses the following equation to calculate THD%:
HC
THD = -------
- x 100%
H1

thd calculations
thd is an alternate method for calculating total harmonic distortion that uses the
RMS value for the total harmonic content rather than the fundamental content.

Verifying accuracy EasyLogic™ PM2200 series

Verifying accuracy
Overview of meter accuracy
All meters are tested and verified at the factory in accordance with International
Electrotechnical Commission (IEC) and Institute of Electrical and Electronics
Engineers (IEEE) standards.
Your meter typically does not require re-calibration. However, in some installations
a final accuracy verification of the meters is required, especially if the meters will
be used for revenue or billing applications.

Accuracy test requirements

The most common method for testing meter accuracy is to apply test voltages and
currents from a stable power source and compare the meter’s readings with
readings from a reference device or energy standard.

Signal and power source

The meter maintains its accuracy during voltage and current signal source
variations but its energy pulsing output needs a stable test signal to help produce
accurate test pulses. The meter’s energy pulsing mechanism needs
approximately 10 seconds to stabilize after every source adjustment.
The meter must be connected to control power in order to conduct accuracy
verification testing. Refer to your meter’s installation documentation for power
supply specifications.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Verify the device’s power source meets the specifications for your device’s
power supply.
Failure to follow these instructions will result in death or serious injury.

Control equipment
Control equipment is required for counting and timing the pulse outputs from an
energy pulsing LED.
• Most standard test benches have an arm equipped with optical sensors to
detect LED pulses (the photodiode circuitry converts detected light into a
voltage signal).
• The reference device or energy standard typically has digital inputs that can
detect and count pulses coming from an external source (i.e., the meter’s
pulse output).
NOTE: The optical sensors on the test bench can be disrupted by strong
sources of ambient light (such as camera flashes, florescent tubes, sunlight
reflections, floodlights, etc.). This can cause test errors. Use a hood, if
necessary, to block out ambient light.

NHA2778902-11 77
EasyLogic™ PM2200 series Verifying accuracy

Environment
The meter should be tested at the same temperature as the testing equipment.
The ideal temperature is about 23 ºC (73 ºF). Make sure the meter is warmed up
sufficiently before testing.
A warm-up time of 30 minutes is recommended before beginning energy accuracy
verification testing. At the factory, the meters are warmed up to their typical
operating temperature before calibration to help ensure that the meters will reach
their optimal accuracy at operating temperature.
Most high precision electronic equipment requires a warm up time before it
reaches its specified performance levels. Energy meter standards allow the
manufacturers to specify meter accuracy derating due to ambient temperature
changes and self-heating.
Your meter complies with and meets the requirements of these energy metering
standards.
For a list of accuracy standards that your meter complies to, contact your local
Schneider Electric representative or download the meter brochure from
www.se.com.

Reference device or energy standard

To help ensure the accuracy of the test, it is recommended that you use a
reference device or reference energy standard with a specified accuracy that is 6
to 10 times more accurate than the meter under test. Before you start testing, the
reference device or energy standard should be warmed up as recommended by
its manufacturer.
NOTE: Verify the accuracy and precision of all measurement equipment used
in accuracy testing (for example, voltmeters, ammeters, power factor meters).

Verifying accuracy test

The following tests are guidelines for accuracy testing your meter; your meter
shop may have specific testing methods.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate Personal Protective Equipment (PPE) and follow safe
electrical work practices. See NFPA 70E, CSA Z462 or other local
standards.
• Turn off all power supplying this device and the equipment in which it is
installed before working on or in the equipment.
• Always use a properly rated voltage sensing device to confirm that all power
is off.
• Do not exceed the maximum ratings of this device.
• Verify the device’s power source meets the specifications for your device’s
power supply.
Failure to follow these instructions will result in death or serious injury.

1. Turn off all power supplying this device and the equipment in which it is
installed before working on the device or equipment.
2. Use a properly rated voltage sensing device to confirm that all power is off.

4. Connect the control equipment used for counting the standard output pulses
using one of these methods:

Option Description

Energy pulsing LED Align the red light sensor on the standard test bench armature over
the energy pulsing LED.

Pulse output Connect the meter’s pulse output to the standard test bench pulse
counting connections.

NOTE: When selecting which method to use, be aware that energy

pulsing LEDs and pulse outputs have different pulse rate limits.
5. Before performing the verification test, let the test equipment power up the
meter and apply voltage for at least 30 seconds. This helps stabilize the
internal circuitry of the meter.
6. Configure the meter’s parameters for verifying accuracy testing.
7. Depending on the method selected for counting the energy pulses, configure
the meter’s energy pulsing LED or one of the pulse outputs to perform energy
pulsing. Set the meter’s energy pulse constant so it is in sync with the
reference test equipment.
8. Perform accuracy verification on the test points. Run each test point for at
least 30 seconds to allow the test bench equipment to read an adequate
number of pulses. Allow 10 seconds of dwell time between test points.

Required pulses calculation for accuracy verification

testing
Accuracy verification test equipment typically requires you to specify the number
of pulses for a specific test duration.
The reference test equipment typically requires you to specify the number of
pulses required for a test duration of “t” seconds. Normally, the number of pulses
required is at least 25 pulses, and the test duration is greater than 30 seconds.
Use the following formula to calculate the required number of pulses:

NHA2778902-11 79
EasyLogic™ PM2200 series Verifying accuracy

Number of pulses = Ptot x K x t/3600

Where:
• Ptot = total instantaneous power in kilowatts (kW)
• K = the meter’s pulse constant setting, in pulses per kWh
• t = test duration, in seconds (typically greater than 30 seconds)

Total power calculation for accuracy verification testing

Accuracy verification testing supplies the same test signal (total power) to both the
energy reference/standard and the meter under test.
Total power is calculated as follows, where:
• Ptot = total instantaneous power in kilowatts (kW)
• VLN = test point line-to-neutral voltage in volts (V)
• I = test point current in amps (A)
• PF = power factor
The result of the calculation is rounded up to the nearest integer.
For a balanced 3–phase Wye system:
Ptot = 3 x VLN x I x PF x 1 kW/1000 W
NOTE: A balanced 3–phase system assumes that the voltage, current and
power factor values are the same for all phases.
For a single-phase system:
Ptot = VLN x I x PF x 1 kW/1000W

Percentage error calculation for accuracy verification

testing
Accuracy verification testing requires you to calculate the percentage error
between the meter being tested and the reference/standard.
Calculate the percentage error for every test point using the following formula:
Energy error = (EM - ES) / ES x 100%
Where:
• EM = energy measured by the meter under test
• ES = energy measured by the reference device or energy standard.
NOTE: If accuracy verification reveals inaccuracies in your meter, they may be
caused by typical sources of test errors. If there are no sources of test errors
present, please contact your local Schneider Electric representative.

Accuracy verification test points

The meter should be tested at full and light loads and at lagging (inductive) power
factors to help ensure testing over the entire range of the meter.
The test amperage and voltage input rating are labeled on the meter. Refer to the
installation sheet or data sheet for your meter’s nominal current, voltage and
frequency specifications.

Inductive load (lagging 100% of the nominal current, 100% of the nominal voltage and nominal
power factor) frequency at 0.87 lagging power factor (current lagging voltage by 30°
phase angle).

Energy pulsing considerations

The meter’s energy pulsing LED and pulse outputs are capable of energy pulsing
within specific limits.

Description Energy pulsing LED Pulse output

Maximum pulse frequency 35 Hz 20 Hz

Minimum pulse constant 1 pulse per k_h

Maximum pulse constant 9,999,000 pulses per k_h

The pulse rate depends on the voltage, current and PF of the input signal source,
the number of phases, and the VT and CT ratios.
If Ptot is the instantaneous power (in kW) and K is the pulse constant (in pulses
per kWh), then the pulse period is:
3600 1
Pulse period (in seconds) = =
K x Ptot Pulse frequency (Hz)

VT and CT considerations
Total power (Ptot) is derived from the values of the voltage and current inputs at
the secondary side, and takes into account the VT and CT ratios.
The test points are always taken at the secondary side, regardless of whether VTs
or CTs are used.
If VTs and CTs are used, you must include their primary and secondary ratings in
the equation. For example, in a balanced 3-phase Wye system with VTs and CTs:
VTp CTp 1 kW
Ptot = 3 x VLN x xIx x PF x
VTs CTs 1000 W
where Ptot = total power, VTp = VT primary, VTs = VT secondary, CTp = CT
primary, CTs = CT secondary and PF = power factor.

NHA2778902-11 81
EasyLogic™ PM2200 series Verifying accuracy

Example calculations
This example calculation shows how to calculate power, pulse constants and
maximum pulse frequency, and how to determine a pulse constant that reduces
the maximum pulse frequency.
A balanced 3-phase Wye system uses 480:120 volt VTs and 120:5 amp CTs. The
signals at the secondary side are 119 volts line-to-neutral and 5.31 amps, with a
power factor of 0.85. The desired pulse output frequency is 20 Hz (20 pulses per
second).
1. Calculate the typical total output power (Ptot):

Ptot = 3 x 119 x 480 x 5.31 x 120 x 0.85 x 1 kW = 154.71 kW

120 5 1000 W

2. Calculate the pulse constant (K):

3600 x (pulse frequency) = 3600 seconds/hour x 20 pulses/second
K=
Ptot 154.71 kW

K = 465.5 pulses / kWh

3. At full load (120% of nominal current = 6 A) and power factor (PF = 1),
calculate the maximum total output power (Pmax):

Pmax = 3 x 119 x 480 x 6 x 100 x 1 x 1 kW = 205.6 kW

120 5 1000 W
4. Calculate the maximum output pulse frequency at Pmax:

Maximum pulse frequency = K x Pmax = 465.5 pulses / kWh x 205.6 kW

3600 3600 seconds/hour
Maximum pulse frequency = 26.6 pulses/second = 26.6 Hz
5. Check the maximum pulse frequency against the limits for the LED and pulse
outputs:
• 26.6 Hz ≤ LED maximum pulse frequency (35 Hz)
• 26.6 Hz > pulse output maximum pulse frequency (20 Hz)
NOTE: The maximum pulse frequency is within the limits for LED energy
pulsing. However, the maximum pulse frequency is greater than the limits
for pulse output energy pulsing. Pulse output frequencies greater than 20
Hz will saturate the pulse output and cause it to stop pulsing. Therefore in
this example, you can only use the LED for energy pulsing.

Adjustments to allow energy pulsing at the pulse outputs

If you want to use the pulse output, you must reduce the output pulse frequency
so it is within the limits.
Using the values from the above example, the maximum pulse constant for the
pulse output is:

3600 x (pulse output maximum pulse frequency)

Kmax = = 3600 x 20
Pmax 205.6
Kmax = 350.14 pulses per kWh

82 NHA2778902-11
Verifying accuracy EasyLogic™ PM2200 series

1. Set the pulse constant (K) to a value below Kmax, for example, 300 pulses/
kWh. Calculate the new maximum output pulse frequency at Pmax:

New maximum pulse frequency = K x Pmax = 300 pulses/kWh x 205.6 kW

3600 3600 seconds/hour
New maximum pulse frequency = 17.1 pulses/second = 17.1 Hz
2. Check the new maximum pulse frequency against the limits for the LED and
pulse outputs:
• 17.1 Hz ≤ LED maximum pulse frequency (35 Hz)
• 17.1 Hz ≤ pulse output maximum frequency (20 Hz)
As expected, changing K to a value below Kmax allows you to use the pulse
output for energy pulsing.
3. Set the new pulse constant (K) on your meter.

Typical sources of test errors

If you see excessive errors during accuracy testing, examine your test setup and
test procedures to eliminate typical sources of measurement errors.
Typical sources of accuracy verification testing errors include:
• Loose connections of voltage or current circuits, often caused by worn-out
contacts or terminals. Inspect terminals of test equipment, cables, test
harness and the meter under test.
• Meter ambient temperature is significantly different than 23 °C (73 °F).
• Floating (ungrounded) neutral voltage terminal in any configuration with
unbalanced phase voltages.
• Inadequate meter control power, resulting in the meter resetting during the
test procedure.
• Ambient light interference or sensitivity issues with the optical sensor.
• Unstable power source causing energy pulsing fluctuations.
• Incorrect test setup: not all phases connected to the reference device or the
energy standard. All phases connected to the meter under test should also be
connected to the reference meter/standard.
• Moisture (condensing humidity), debris or pollution present in the meter under
test.

Power and power factor

Power and power factor
The sampled measurements taken at the meter’s voltage and current inputs
provide data for calculating power and power factor.
In a balanced 3-phase alternating current (AC) power system source, the AC
voltage waveforms on the current-carrying conductors are equal but offset by one-
third of a period (a phase angle shift of 120 degrees between the three voltage
waveforms).

Current phase shift from voltage

Electrical current can lag, lead, or be in phase with the AC voltage waveform, and
is typically associated with the type of load — inductive, capacitive or resistive.
For purely resistive loads, the current waveform is in phase with the voltage
waveform. For capacitive loads, current leads voltage. For inductive loads, current
lags voltage.
The following diagrams show how voltage and current waveforms shift based on
load type under ideal (laboratory) conditions.

Current and voltage in phase (resistive) Current leads voltage (capacitive) Current lags voltage (inductive)

Real, reactive and apparent power (PQS)

A typical AC electrical system load has both resistive and reactive (inductive or
capacitive) components.
Real power, also known as active power (P) is consumed by resistive loads.
Reactive power (Q) is either consumed by inductive loads or generated by
capacitive loads.
Apparent power (S) is the capacity of your measured power system to provide real
and reactive power.
The units for power are watts (W or kW) for real power P, vars (VAR or kVAR) for
reactive power Q, and volt-amps (VA or kVA) for apparent power S.

Power flow
Positive real power P(+) flows from the power source to the load. Negative real
power P(-) flows from the load to the power source.

Power factor (PF)

Power factor (PF) is the ratio of real power (P) to apparent power (S).
PF is provided as a number between -1 and 1 or as a percentage from -100% to
100%, where the sign is determined by the convention.
P
PF = —
S

A purely resistive load has no reactive components, so its power factor is 1 (PF =
1, or unity power factor). Inductive or capacitive loads introduce a reactive power
(Q) component to the circuit which causes the PF to become closer to zero.

True PF and displacement PF

The meter supports true power factor and displacement power factor values:
• True power factor includes harmonic content.
• Displacement power factor only considers the fundamental frequency.
NOTE: Unless specified, the power factor displayed by the meter is true power
factor.

EasyLogic™ PM2200 series Power and power factor

Power factor sign convention

Power factor sign (PF sign) can be positive or negative, and is defined by the
conventions used by the IEEE or IEC standards.
You can set the power factor sign (PF sign) convention that is used on the display
to either IEC or IEEE.

PF sign convention: IEC

PF sign correlates with the direction of real power (kW) flow.
• Quadrant 1 and 4: Positive real power (+kW), the PF sign is positive (+).
• Quadrant 2 and 3: Negative real power (-kW), the PF sign is negative (-).

PF sign convention: IEEE

PF sign is correlates with the PF lead/lag convention, in other words, the effective
load type (inductive or capacitive):
• For a capacitive load (PF leading, quadrant 2 and 4), the PF sign is positive
(+).
• For an inductive load (PF lagging, quadrant 1 and 3), the PF sign is negative
(-).

Power factor min/max convention

The meter uses a specific convention for determining the power factor minimum
and maximum values.
• For negative PF readings, the minimum PF value is the measurement closest
to -0 for PF readings between -0 to -1. For positive PF readings, the minimum
PF value is the measurement closest to +1 for PF readings between +1 to +0.
• For negative PF readings, the maximum PF value is the measurement
closest to -1 for PF readings between -0 to -1. For positive PF readings, the
maximum PF value is the measurement closest to +0 for PF readings
between +1 to +0.
